Alright well I am just doing some searching around, trying to see if anyone has really done any extensive work to thier engines, so far it doesn't look like it

The only "extensive" work I have seen done is in the FI area, and even there it looks like they are rather "tame" setups, decently fast nonetheless, but nothing too indepth as far as SEM, and internal buildups, etc.

What I am looking for is to see what kind of NA buildups people have done on the 95-99 3L engine's. Has anyone even gone up in displacement (bored, stroked, etc)?

I know people have done this MIdEast manifold swap, but has anyone done anything else then just swapped it? Headwork, port match, gasket match, raise compression, new internals, etc....

The search doesn't work so I was recomended to post.

TIA

nope..

There are a few ppl in the dallas area that have done unbelevable thing to there max's but like every where else no one want to talk about it sorry

Go to VQpower
I'm sure you'll find something there

I30krab has done some engine work, I believe.

No, to my knowledge no one has cracked open an N/A motor to do anything besides bolt ons. Care to be a guinea pig?

Why would anyone want to crack open a VQ when it can take 12psi of boost and boosting 429hp? j/k!I think that's pretty good for the street already don't you think.

because in the end, it's not a V8, it's a 3L engine that was made for a family sedan, and for 90% of us it's a daily driver. Honestly, tho, if i had the money, time, and another car, i'd definitely invest in more engine work.


"AssayrianRacer" or "TC2Teamshift" or whatever the hell he's calling himself now claimed to have work done on his engine: port & polish, and more.....but then again he claimed that his NA car would beat anything with 4 wheels......

Thanks
Haha well since I dont have a Maxima, I would not make a good candidate for testing.

Yea the 3L was designed for a Maxima... not to be 12psi turbo'd either. Nothing is really used for its specified intent, thats the bueaty of engineering.

Anyways back on topic. I dont know if you guys have ever driven in well built NA cars, but its an entirely different feel then FI... obviously. And in most cases the NA feels better, easeir to drive/race/track.

If people try to argue that the cost to do NA stuff is too much..go and try to do a similar Turbo setup and it'll cost the same... in almost any scenraio (meaning any car).

I would like to know what that one guy has done though, specifically, because he 95-99 engine is pretty decent in design, basic in that, but still has good NA potential.

Its pretty surprising with all thesepeople sinking thousands and thousands into thier car they dont try to do an NA buildup, because it would surely be worth it.

I am sure you guys cna tell by my membername I own a VR6 (MK3 GTI). Anyways the buildups on Vr6's has been extensively done from 1000hp turbo setup in RWD tube frames to 3.1L (2.8 stock) TAME 230whp race engines.

Anyways Thanks for the replies as I was just curious what was out there since I have never seen a "fast" NA maxima engine, only ones with bolt ons... which are pretty basic stuff.

Headwork, Intake Manny, some port matching, gasket matching, raise the CR a bit, rebuild the valvetrain, and right there is a pretty powerful beast. The ONLY problem I see is software, which is another issue I have with the engine. It seems like NOONE has done anything with stand alone systems on maximas, or even mid range piggyback setups.

Obviously we know the maxima is a "sedan family car" but you guys are sinking thousands in anyways, might as well get good power out of it. I am sure guys over the pond have done up maxima's, but noone seems to know anything from experience here in the US..

Eitherway I gotta go back to studying, thanks for the info guys.
peace

Sorry about the other thread, "Thanks" I am not used to this sketchy forum, it needs some updating


ALSO whats on vqpower, I couldn't find anything good

Also V8's are not the only nA engines, actually a lot of other engines are better then v8's in some cases, in fact for size they are MUCH better. So dont think Displacement is key.


And you said someone did P&P, but thats not as in depth as I was talking about. ALL the intake manifold swaps should be port and gasket matched regardless, its a place where you can gain major power and smoother power band.

Who will be the first NA max in the 12's?

i dont think thats possible.......if so prove me wrong. and no cheatrous either "nitrous"

NeAlOc iZ In tHa 13.7 aReA n/a yO

Think about it , someone like nealoc 187 has just scrached the surface on what can be done.And with a 2500lbs max i could do this and still make my max look normal.And what about cams with 7500 REV LIMIT.

he has more then scratched the surface....i think hes got 13.8? i mean another .9 NA to 12.9 is alot of time. He has his car basically maxed out with mods.....im not saying it CANT be done im simply saying without ripping apart your motor spending all the time and money into it to just try to get into the 12's. I love my maxima, but its a maxima.. i can see 5th and 6th gens breaking into 12's especially 03's with setups like nealoc. peace.

Yes and sombody once said the same things about civics they run 10's na. Na power is better than boosted power look at 2003 april SCC p 142 there are 4 civics 3 na 1 boosted . The three na run 12's the turbo one 13's. The one that is na runs 12.6 with 151 @ fwh this was done cheaper than turbo car, HP to weight ratio is your frind. You need to focus on weight just as much as power. And it does cost money but that is what work is for.

And are they streetable? Nope. No way a 1.8 liter engine will hit 10's without major weight reduction on the cars part.

Just to correct your info. Neal ran a 13.9 with intake, Y-pipe, Mevi, slicks, and a littel weight reduction.

I would not call that maxed with mods.

What you are really doing here is trying to compare N/A to All Motor. There is a big difference, All Motor cars are running 10's because they are built engines with major weight reduction not stock engines with a few bolt-ons and minor weight reduction.

Its like comparing a marathon to a 10k.

An N/A car is a "naturally aspirated" car, which would also make it an "All Motor" car. I don't get what you were trying to say Jime...Boosted and All Motor maybe?

Yeah true, there is still some stuff that he could do such as underdrive pulley, test pipe, catback exhaust, lightned flywheel, clutch (to help launches), and a little more weight reduction. But nothing that is really going to make that much of a difference (the .6 or.9 diff that he would need), he already has all the good N/A power gaining mods. But he has not even ran with the JWT ECU yet, so he should be able to do better than a 13.9 with that, maybe a 13.7 or 13.6? It sounds like it made a big difference in power for him. Has anyone experimented with a larger throttle body yet? Doesent MardiGrasMax have a 3.5 liter pathfinder TB? I think that N/A 12's may be possable but it would take a nearly gutted car to do so.

An All Motor car is a built engine. It is a RACE CLASSIFICATION and the term is misused by most people.

N/A and All Motor are not the same. N/A is a stock engine, even with bolt-ons. All Motor is not a stock engine, it is built from the ground up. Its a race engine.

I would love to hear you tell Aguilar, Padilla or Paryoonto that they are N/A running low 10's All Motor cars.

You may not think there is any difference but its MAJOR.

I have the pathy TB on my max also, i have not started the car yet because of other projects. You do not have to strip the car to make it light, for instance the stillin intake bracket is steel i made one out of aluminum. My bracket is 70% lighter, it also looks alot better ,little things add up. The goal for my max is 2500lbs and 250 flywheel HP. Ive got the weight reduction all mapped out,12.9 here i come.

The last I heard Mardigrasmax was gonna stroke out to a 3.8L. The cylinder walls are too thin I heard, though. If he does do the 3.0VQ --> 3.8VQ he will be my personal hero and I will send him fan mail.

He still has a good 1/2 second he can get out of the rest of the bolt-ons. The ECU will be the majority that .5 seconds.

A 12 second maxima without forced induction is attainable if you crack the motor open, with every bolt on you can think of though I don't think they'll get any faster than 13.4ish on slicks and with significant weight reduction, more significant than anyone's done so far.

I'm kindof lost on the point of this thread though. I almost get the feeling it's a VR6 guy coming over here on a power trip because there are built all motor VR6s and no built all motor VQs... I sincerely hope that's not the case because that's really lame if someone just came on here to say "we've got more built motors than you :P"

The reason for that is there is about 10x the following, and 10x the parts for VR6s as compared to the VQ, not because of the capabilities of the motor.

I'm also confused as to what you're saying about "the guys sinking thousands and thousands of dollars into the car". Most of these people are doing it for the looks, or for bolt on forced induction. If I took all the money I've spent on suspension and tires and wheels and put it into my motor I could have an all motor max, and it would still be stock height and on stock wheels and stock rubber. That's not very cost effective in my mind. A car that makes tons of power and can't put it down to the ground, not cool.

If this was a friendly thread then I apologize for being skeptical, but to me it seems very much like a "VR6s are better than VQs because more guys are spending more money on them" thread, and that just sucks.

Nealoc your thoughts on what my intent of this thread are entirely FALSE!

I used to do work on Arnaud (aka Maximarider) 95 and some stuff on his 97. I think there is a lot of potential in the maxima's, it just seems noone has really dove into as much as they could.

And I am not a vr6 on a powertrip, if anything I am an S52 on a powertrip saying vw's suck b/c they are fwd and handle like **** with the vr6. If you dontknow the S52 is the 3.2l in the E36 Bimmers. As we're finally getting an e36 racecar for me to race and design/engineeer/fabricate parts for this summer, I am more of a bimmer enthusiast then anything, Arnaud can back me up on that.

But my intent of the thread was to see the progress people have made with Na max's in the 4th generation (the engine anyways).

Also to that guy who was talking about NA and all motor. he was right in saying ALL motor is a "classification," however all "ALL motor" cars are NA, however not all NA engines are "all motor." Just to make everyone happy

Back to the topic I intended for this to be in the first place: I am trying to see what kind of stuff has been done to the engine. I understand the "org" is more involved with looks, i.e "styling" but just because you have show doesn't mean you can't have go. However "show" in my opinion means its a dedicated racecar. I am not a fan of drag racing nor show cars, however I respect them both, as theres a great deal of awesome technology and innovation in both those fields, moreso in dragracing.

I think the people running high 13's with bolt ons, weight reduction and slicks might just need mroe time/practice in the car. I dont drag, but NJ (around NJ anyways) is home to the fastest vr6 draggers in the country, so its spoken about a lot on the vortex... So i hear it all day long Basiucally, like any motorsports, the driver is the key component. The car's optimum time will be how well the driver can get out of the hole, and how little mistakes he makes, just like in road racing (my field). There is no such thing as a "perfect lap" nor a "Perfect 1/4" the fastest will just be the one with the leats mistakes, hence the car will not always be the issue. I am sure all have you have seen videos of 400whp cars only doing high 13's which is pathetic, b/c its all driver error.

Anyways we're all iced in on a friday night, so I gotta find something today before the power goes out.

Sorry again for the confusion, but this was not intended for any hate of "vr6 power" boasting, merely an engineer interested in the developments of the maxima engine. Hell the Vr6 has not even been that well developed either for na, people are only just doing ITB setups now in the US! However normally the dedicated road racing crowd I am normally around have the top of the line components and run in a class of thier own, not comparable to ANYTHING that can be run on the street, so its kind of a mind set I am into where the bst there is, is basically the best money can buy, which will always perform better if the driver can handle it. So if you can do it right the first time and buy the best of the best.


And to end this, I hope to see maxima'as in the 12's soon NA, sounds like $12K should get a car into 12's, which includes engine overhaul, tranny rebuild, tires, light wheels, all the normal bolt ons, piggy back ecu tuning (dyno tuned preferably and tuned at the track). The only VR6 thing I can boast about is that they are similar to the maxima in that its a 6cyl fwd front engine car, so to say a maxima cant keep up is ridiculous, some of these vw guys just crazy... I mean they are hitting 9's this coming season for sure! Also there has been a 1000hp+ vr6 rwd tube frame drag car built, so its been run through all its turbo stages, and dozens of high end race na blocks have been made, running 228whp on race compression, however with stand alone, itb, that number cna easily go past 250whp.

Goodnight and I hope my glacier, i mean car melts... its under about an inch of ice right only only hours after I broke it all apart, only took 2 hours

What does cylinder wall thickness have to do with stroking an engine? Im gonna assume he wanted to bore it out as well to get it to 3.8L but it's not absolutely necessary. What people should worry about with a stroked engine (assuming its a serious stroke and not just 0.1L) is piston acceleration and speed... as well as slap due to the extra sideways force applied to the piston through the rods.

Which crank was Mardigrasmax gonna use? Aftermarket or from another Nissan engine?

EDIT: Sorry I was at MAX2000JP's place and I accidentally posted my reply under HIS name not mine. I've cut and pasted it and posted it under my name to avoid futher confusion, sorry guys.

Good I'm glad I was wrong about your intent. Yes I know about the S52, I'm more a fan of the S50 though, it responds better to bolt-ons. Or an S52 with OBD-I conversion

Yep, S50 3.0L OBDI is nice, and the euro S50 is what most of the road rce guys use, putting out about 350hp on a reasonably life race engine for club racing. The 24 hour euro S50/s52's are about 450hp.

The S52 converted to obdI is a great setup, however for a club racer, the S50 is a bit better because of its potential with the 3.2 crank, etc...

No prob about posting under the wrong name, just glad we are on the same page now, literally

I'll have a bmw racecar this summer finally, if I am lucky it'll hav an S50 in it (meaning its an m3) however most likely it'll be a WC 325/328 with a 270-290hp setup. I cant wait to race it!

G"night and dont forgrt to turn your clocks ahead an hour damn dayl light savings time!

Just to let you guys know we drive a nissan maxima, not a skyline not a supra. why spend all this money to redo an engine, I have other mods like an intake, exhaust, and y-pipe, thats ok. But rehauling your engine thats crazy expensive, if your into speed and racing that much the maxima is not for you.

Because the Maxima has the VQ Engine - one of the most efficient V6's you can buy.....


It would be a shame for people not to build them up.

Some people are in it for the speed, some people are in it for the art....and the speed.

So,what are you into it for speed or art? Are you going to be the first to build them up?HEHE j/k.

If I had the money, I would tinker with these ideas in a heartbeat.

But life in general doesn't permit it right now.....

Haha, well if you are trying to say its not for speed, then who says its for looks?

So you are saying it would be more worth it to build a $7500 audio system that you cant even use 75% of the time...

You are saying the Maxima was biult yo have the body redone? What makes it able to have the body redone and not the engine?

I think you are stereoetyping maxima owners for being all show and now go. With ANY car there is always the "racers" who care about its function not its form. And for them the function makes the form the best, basic and to the point.

Either way, dont get the thread off topic.

I would garuntee most people would be happier with a strong engine then a nice sounding audio system, whether they think it or not, once they drove the car they would fall in love

The "art of it" isn't anything about looks - it's alot more than that....

I mean the art of learning, tinkering, playing, enjoying....not just looks or speed......

I personally am all about go, not show. My car is older, with a few battle scars because of where I work, But it still looks good. The potential for the VQ as a built motor is simply amazing. Nissan has designed them for racing upwards of 400+ hp NA. Hell the new VQs are putting 280 hp NA in the 350z. I was hoping to start building one up from the ground, especially since my old motor died, and I'm getting a new one dropped in next week. My mechanic told me if I wanted it, I could have the old engine, and I've been very tempted to take it, but since I live in an apartment, I have no shop, and no tools to do it with I really can't do it, which makes me more than a little unhappy.
I have had alot of ideas to build one up, both from using off the shelf parts, and custom built ones as well, but again, since I dont have the space, I'm going to have to let that dream die for now. I am taking the intake and exhust manifolds, as well as the camshafts to play with since the old engines gonna rust away in the rain behind his shop, but for now thats all I can do.

With a few exceptions, there are just not enough maxima owners who are interested in spending thousands of dollars to attempt to mod their engine in new ways without even knowing what kind of gains they could get. I love my car and will continue to mod it, but only within reason, this car is pretty much working to hold me over until I can afford a real sports car.

Try this, build up the motor and then get a ECU, Make your car more stable, Suspension, Raise it up a few inches in the back, and lower it in the front, (for better grip) get something that reduces Wheel Hop, The widest Z rated tires you can fit, with steel rims, (the ones that you put hub caps on) cause they are light, Weight reduce the Max, get 3" exhaust with 3" y-pipe and all the other pipes, this has to be an Auto with a Torque Converter, A Valve Body Mod and a Tranny Cooler, Or a Really Really good Stick Driver, Also increase the Rev Limiter to 7500, o also the VQ38 mod that one guy is doing to his car, If it doesnt run 12's or under, get a SC then you can be running REALLY REALLY low
