Well Im in the middle of deciding what to do. I really want to do a NA setup, get some custom pistons (probably 92 or 93mm, 12:1 cr or so), cams, a little porting and rev to about 7K or so, and make good power. It sound mean as hell, and still get good mpg, but then thats all the power Ill get out of it. Sure 230-260hp is fast, and NA would sound mean.

But then theres the Turbo option. If I went this route, Id make a setup that put the turbo over the tranny, and Id run low low boost at first, so Id run the turbo straight into the intake manifold, the intake piping wouldnt be more then 3 feet from air filter to cylinders. Im going for extra power, but very responsive. Oh and for cooling, Id run a water injection. with some cams on this option, It would be crazy reponsive and have top end power.

Either setup Id use a zemulator or similar on the stock ECU, and for both setups Id probably run 370cc inj's.

So for a daily driver would you go really reliable NA setup, or low boost? I think the turbo setup would prove cheaper as Id probably use something similar to a Z31 stock turbo and do all my own fab.

Im leaning turbo, but NA would truely be unique, but no more potential. And either way Id piece this together over the winter.

Any way give me some worth while input.

If you go turbo you will not stay on low boost.

 

OOOO So true

 

Turbo lag sucks...especially for daily driving.... an NA 3rd gen in the 230-260 range would be NICE...And i think you'd be the first one...

gl with whatever u decide to do

 

start with low boost.
a properly sized turbo won't lag.
and I thought you need the maf between turbo and intake.

 

You need to watch Best Motorings turbo vs na shootout.

EDIT: Its not on video google anymore wtf.

 

Dude... you're pushing that block going with 92mm. That's why I'm going with 91mm at 11:1

 

You can do either. Most stock cars have the maf before the turbo, but high boost applications often see the mafs on the charged side. I'm fairly ignorant on the matter, so please enlighten me boosted guys...

 

depends on the turbo.... if he puts a big **** turbo on it then it'd be a factor

 

its funny that the only people that say this are non turbo...

 

Whats NA?

10char.

 

Turbo lag sucks, and I've got a turbo.

 

Naturally Aspirated

 

Naturally Aspirated. The engine making power using nothing but itself, with no add ons to help force air in.

 

Yeah, get the right size turbo. When I'm off boost I feel like I'm driving my VG...

 

If I went turbo, Id get a stock z31 turbo or slightly bigger. Nothing like the size of maxmaxima91's, at least not at first.

And Id put the turbo over the transmission, like maxmaxima91's too, but since its low boost, Id run the outlet right into the intake with some water injection cooling, so my setup would be very responsive.

Kcidmil, what turbo do you have and on what?

89blackse, do you know what turbo your VE has?

~Alex

 

Thanks for the reply, now I have another question... How can this Natural Aspiration be done?

 

its what the VG and VE come as stock lol.

Natual asperation means, the engine doesnt have a turbo, super charger or has a nitrous oxide system on it. Forced induction means its turbo or supercharged, and to a small degree a N20 system is considered Forced induction.

NA means the engine is pumping air in and out by its self, no help.

Something similar to this,



In this.



The sole purpose for buying this truck was so I could haul my Maxima, and it's parts when I move. Now how's that for a mod? That currently puts the amount of money I spent on my Maxima up to $23500.00 or so.

 

Someone hasn't been playing or reading upgrades on Grand Turismo

 

t3/60-1 Garrett turbo (.63 exhaust / .70 compressor)

Personally I would go with NA mods. So much less to worry about.

 

cams... where? i search and search... wth i cant find any 3rd gens... people under estimate them, A LOT

and thats why there cool and you can make them all custom and crap

and... its kinda hard if you dont know what your doing like... me

BUT and you guys help me a lot!!!

i will soon anyways waiting for my card

 

Dude... you're not searching too hard. www.jimwolftechnology.com The same cams can also be found here. www.cattmanperformance.com

heck, you want bigger pistons, or just a higher CR out of your stock size? www.importperformance.net

I've got a nice list in my favorites, had so many I had to put them in their own folder. And I'm sure Matt and Craig have a list longer than mine.

 

well With the right size turbo lag will not be an factor. Its funny a na guy also ways says "turbo lag sucks" I race a 5th gen with the 3.5 in it and he could only pull a half a car before I built full boost and was right back around him. So how is that lag?

 

Look a few posts, I already commented on that.

 

Are people reading that Im going to use a Z31 or similar size turbo, with a super short routing? lag...well there wont be any.

~Alex

 

I had a ct26 with is a larger than the z31 turbo. I had it intercooled and long pipes. Turbo lag was not hardely noticeble and torque was insane. 341wtp at 10 psi

 

If you got thousands to spare, go turbo. Otherwise stay NA. I had originally thought the turbo would be cheap, but it was the small things that really added up! Even NA, things can add up quick. I suggest Schneider Cams and regrind your stock cams. They utilize JWT specs on their cams (or used to). Oversized pistons are going to cost, I was quoted $800. Nissan makes 20 over pistons, but they are being put on the "obsolete" list...took me 4 months and personally calling Nissan to get them. You simply need to consider your goals. You can make mad power NA, but there is a ceiling. FYI, I have over $3K just in the engine... does not include turbo, exhaust, piggyback system, boost control, or piping for turbo. Good luck!

 

Why does my 3 liter maxima engine only have 150 hp? Yada yada yada low hp per liter= ricer talk, but what is a starter mod to bring the hp per liter up to a resonable level?

 

$650 through Flatlander Racing, includes rings. and that was for 91mm pistons with 11:1 CR. or if you don't feel like custom pistons... www.importperformanceparts.net They have HP Engine kits for around $1500. Includes pistons, rings, new rod, and crankshaft bearings, and gaskets.

If youi also want to strenghten the internals, go with the VG30DE piston rods.

 

dude theres no CAMS for our VE's just for VG i dont like it!

and what do you mean by shaving the cams that sounds neat-o

 

you have 160 hp

what to you is a reasonable level?
your average ricer civic is running a 1.5 with 102hp
a regular b18b1 swap is 1.8 with 140hp
hp per liter is not a good comparison it's HP per lb that makes the difference.

 

Its not shaving, they add material to the cam, then re-grind it to what ever specs you want. The upgraded cams you get back are the exact same ones that came in the car, they just have more material that happens to make more power

~Alex

 

That's only if you go to the right place... most of them cut down ont he base circle of the cams and you wind up having to shim the cam towers to lower the cam into the right place. done properly, they will weld additional metal on, regrind them, and then nitride-harden the cams again.. but you're looking at a $1500 cam job there. not a $500 typical regrind done by Isky and the like.

 

And good luck finding someone to do the proper R&D on the limited production VE with varible cam timing.

 

yup.. which is why I didn't mess with it when I rebuilt minea few months ago..

even at $1200 for cams, that would be a drop in the bucket compared to what I spent on the rest of the engine.

 

You got the track **** back up and running!?!?

 

Maybe I got lost, I thougt that Alex you have a 1990 SE (VG)? Where did all this stuff start about VE's? Call me daft, but when people start talking about one engine versus another when a thread begins about a particular engine and mods, it begins to lose productivity due to shift in focus and attention away from the topic. We talking VG or VE here?

 

i want to talk baout.... VE's! lol because i like the WHOLE entire thing about my maxima plus i need INFO! i like to read about this stuff

 

i was planning to turbo my VG, but that got put on hold when i started driving my AE86. OMG THAT IS SUCH A FUN CAR
