VQ35 swaps are starting to happen in the All-Motor forum, so whose SC'd car is going to be first?

My bet is StephenMax in the next 9-12 months.

IMO, using the 10:1 Pathy heads on the Altima/Maxima VQ35 block would be the easiest, since each gen could use their own LIM/injectors/rail/intake manifold. Toss in some cam sprocket spacers and aftermarket cams and 400-450whp with a lot more torque then the VQ30.

Anybody considering this route?

 

Isn't Mardi building a 3.5? I would think that he would be ahead of Stephen.

 

SC...not turbo....

 

Hmmmm, i may look into it this summer, but right now i am done with the max and starting to save for my 240sx w/ a RB25DET!!!!!!!

 

Why waste your money on a RB25DET, when you can put a VQ30 or even VQ35 in it?

I'm buying a 240SX soon and someday I will put a VQ in it.

 

Thats because your a idiot. I am torn between the RB or the SR20DET. I just want a engine that has a good aftermarket support and products that are tried and true. The VQ35 would be nice, but the RB has awesome potential and it is sort of a common swap so there is alot of info on it.

 

i think if you keep a stock internals motor, the RB would be better.

 

VQ30DET would be so much better.
The RB is kind of old technology. I really wouldn't waste time with a SR. There really isn't a whole lot of need for aftermarket support for an RB or a VQ30DET. A big turbo and you are done.

 

I agree. VQ30DET or a VQ35DE + turbo would be teh win in a 240. Lighter engine than the RB, possibly lighter than the iron block SR even. But you can do what you want. I'm kindof wishing I had just built a VQ 240 instead of doing a turbo maxima. My loyalty is to the engine, not the body style and certainly not the drivetrain configuration.

Anyways I think stephenmax is probably the most likely candidate for the topic of this thread.

 

I'm with you neal. I just sat down today and was pricing parts for my 240 project and i wanted to kick myself in the nutts. I could have made a bad A$$ S14 for the amount of money i dumped in my max. But then i took my car for a drive and i couldn't help but love it again. I look at it this way, when i get done with the 240, then i will have 2 bad a$$ cars

 

Old or not, that RB is strong as all get out and is can make some mad monkey stomping power. Face it Spig, i will not get the VQ30DET, it isn't going to happen

 

Chris'smax,

What are your plans for the 240? if you want to drag it I would go with the RB, but if you want to drift it I would go with something lighter like the SR or the VQ. Either way your going to have a sweeet car.

 

Mostly drag racing. I would probably just play with it on auto cross courses every once in awhile. I am going to paint the car car and do it all up so i don't want to take it out to drift it and tear it all up. I'm to much of a wuss

Btw are you going to turbo your 3.0 or are you going to hold off and do the 3.5 swap and turbo it?

 

Well since you are going to drag it i would go RB.


My car is in Houston at SGP Racing getting my turbo put in. I have all the goodies to get me to 450hp . I also have my spare VQ in my back yard so I plan on driving around for a while, and collect parts for my build 3.5 and then swap it out. once I get the car back I'll let you'll know.

 

woooo, SGP. Man you must have some dough saved up . Once you get it on you need to come to BR and we can take that **** to the track. I'll have to get a nitrous kit though to keep up

 

when you guys refer to the VQ30DET, is that just the vq30 + turbo or the actual jdm gloria/cedric engine. I'd imagine it would be a pain trying to get the wiring down on such a rare jdm engine with absolutely no english info published.

as for the vq35 + pathy heads + SC, would it be more feasible to do vq35 with vq30 timing chain cover + SC?

 

Budgeting is the key. only popcorn to eat and water to drink but the out come is well worth it. how far is BR form SA?, and you'll be at Maxus right? will see what we can work out. I'm always up for a good road trip.

 

Well i was going until i found out my trip to keywest is that weekend. Owell i am going scuba diving and going to sit on the beach and proceed to drink until my face is numb

 

chris'smax,

to bad i would love to see your car in person, it should be a good meet. Well have fun in keywest and drink a couple for me.

 

You could use the maxima ECU and wiring harness. It is the same engine with most of the same sensors. The MAF might be different, but that is it. I am sure the tuning is different.

Ok an RB25DET will cost you what? at least $2500 for engine, tranny, ecu, etc.
A VQ30DET is like $1100 or so and you can use the 350Z 6 speed (more expensive) or the Pathfinder 5 speed (rarer). Both the RB and the VQ have a ton of potential. Both can fit within the engine bay. I personally think the VQ actally has more potential. I know the VQ will have more torque although the RB probably has a higher redline. And the VQ is lighter than the iron block RB yet has a stronger block and is better designed.

For an application like that you wouldn't need crazy aftermarket support. The biggest things you would need would be a new turbo, intercooler, and some other turbo accessories. You really wouldn't need a huge aftermarket support. Most of the aftermarket support you will get will be from Japan and not horribly easy to access. Although I am sure with the growth of the RB25 swap in 240sxs will incease that.

The only thing that would limit you is the tuning capabilites. I would just get a standalone though unless some kind of crazy tuning products comes out for the A32 soon.

 

Point taken grass hopper, but the RB swap has been done time and time again. There are places online that sell custom motor mounts and other things that make the RB swap a direct fitt. If you look(cant remember the site)there is a guy putting in a vq35 and a 350z 6 speed in a 240, but he is having hella issues since the drivetrain is longer and is throwing the shifter position and other things out of whack.

Plus Loc said he could hook me up with the swap for $750

 

interesting....

 

SR is aluminum

 

Sweet stock engine, i might go buy and bug them and see what kind of work they are doing.

 

oh yeah the VQ30DET you could use a maxima ECU which can be easily found. The have the wiring setup at the JWT website.

 

That would be cool, they should have all my piping in by now. And i might be up there this weekend and i'm going to stop by.

 

But getting a harness, seperating what you need/don't need and making it all function will be a pain imho. Does anyone know if most of the VQ engine wiring harness is fairly seperated from the rest of the car's electrics? ie.. wipers/heater/abs/blah?

 

Its all seperate. It seems this idea is popping up all at once. This idea came to me about a month ago. Now all you are talking about it. I do agree that if you're building a drag car the RB is better. If your building a drifter the VQ is the choice but not for the weight. The torque is what makes it an ideal drifting engine. I've never understood how those guys deal with turbo lag when they have to be so precise.

 

Just because we are talking about it in a thread right now doesn't mean we all just thought of it. There have been quite a few threads in the last year or so about this. And that one guy Thaniel has had a VQ powered RX7 since last fall.

 

With a VQ swap there will be some issues like motor mounts and the drivetrain length, but I still think it would be a better swap than a RB.

Loc said he would do a swap for $750 labor? He charged JOn like $1000 or more for a VQ35/30heads swap and Tilley made it to where it was just drop in and plug everything up. And the RB25 swap is not drop in by any means either.
Everything has to be swapped out or modified:
radiator, tranny, steering rack, motor mounts, driveshaft, ecu, wiring harness

I know Travis does engine swaps in 240SXs. He might be able to do it.

Get your maxima done, buy a 240sx, and get the money to be able to do any swap and then we can talk about this Chris.

 

They all use the cutest little BB turbos, so there is none.

 

i was thinking of sc'ing my 3.5 powered 4th gen, it already ran a 13.32 @103 just imagine a sc on top of that.

i just picked up a b13 se-r possible vq swap into that.

 

Did you see that Altima that had a VQ swapped in it on e-bay a couple of months ago? The Vq was pretty tight in there, might be tighter in a b13.

 

Hey, that's me your talking about. It's a VQ30 actually and it's not been that much trouble so far really.

If only u were in my area...that would of been my route considering my upcoming motor swap..with my current S/C.
damn shame cuz of distance we would of made an awesome collaboration to make that happen.

 

Tilley, does the DET IM use a USDM sized TB or is more Pathfinder'ish?

Allen, have you solved the shifter issue yet? You know I've been thinking, its seems like a popular "mod" of the 240 people to move all the controls back a little. All the nice drift cars have floor mounted pedals, a dropped steering column and moved shifter. So if you leave the shifter to far back that would be one of the things solved. Having a center console wouldn't be very feasible but who cares. Also, how do you think the 250 gearing will match up with the 240 final drive? Also, is the 240 diff strong enough to handle the torque? You know the ratio in the 350 & 240 diffs? I'm thinking the 240 is in the mid 3's. They don't seem too high strung.

 

what did you use for motor mounts, driveshafts, tranny, etc?

 

The VQ30DET actually uses something more like the dual TB of the VG maxima. It kind of sucks unless it is much bigger than the 3rd gens but you could always just make an adapter plate for a pathfinder TB or Q45 or something.

 

Any update on this allen? I'm starting into this project full bore pronto. I currently have everything on my car for sale. I also found a Z33 6Spd in Greenbay w/ 9K miles for $900.
