Boost the vq30 or boost the vq35? I'm not sure which route to go so i'm looking for experience (most of you) to assist me with knowledge of the car.

 

pretty much the only diffrence is the VQ35 will spool a bigger turbo sooner and make it easier to make more power. But the VQ30 is very durable and will make plenty of power as is.

What max do you have? Im assuming a VQ30 4th gen since your asking which is better for boost.

Boost the VQ30 and then if you blow it, then swap in a VQ35.

 

I have a 1997 Max not sure if its a gle/glx due to title saying both and i just got it. I am going to be replacing motor because it has 160k on it and i want boost. I like the idea of the 3.5 but is there a kit for it in a 4th gen?

 

You would be using a 4th gen timing cover so they Stillen Supercharger kit would still bolt up.

The only reason I'm against boosting a VQ3.5 is because its ALOT of power for front wheel drive, almost too much if you ask me. A boosted 3.0VQ is more than enough for street use, and great for the track. With a Boosted VQ3.5, you really wont even be able to lay into the throttle at all. If you wanna go 3.5, leave it N/A. Thats just my .02 cents.

Check out my Supercharger Starter Kits below.

I would boost the motor with 160k, you could just get a compression test and do a switch to full synthetic oil (if you haven't already) to check for leaks etc. I agree with Matty a boosted vq35 is alot of power, but after seeing what Mardi has done with the vq30 only real track enthusiast should go for the 35. A supercharged max will throw you back in the seat regardless, the 30 has plenty of power and potential, just check the dyno results.

 

boost the 3L

 

Realistically I wouldn't swap in a motor right now until you have all the bugs worked out. That way if you happen to blow the motor or all hell breaks loose you are only out the 160k mile engine and not a fresh VQ30 or VQ35.

 

Now lets say i do go w/ the vq35 could i still use the pfi turbo kit for it or would i have to go w/ a different kit?

 

answer this question...whats your budget cause there are so many different ways to go about this. also how much power are you looking for?

 

The VQ35 is the same external dimensions and the same exhaust ports. The PFI kit or any other kit will work perfectly except for the TB placement. You might have to mod a pipe or two and doing that on a turbo kit is not the hardest thing you will ever have to do.

A turbo setup that actually is reliable and produces good power will cost a significant amount. Don't add further things to complicate the install (leaving more possibilities of something going wrong)and multiply the amount of money to spend at a time.

Turbo the VQ30 and add the VQ35 later if you want.

 

Try your luck with the motor you have now, and if it dies, replace it with a 3.0L DE-K motor with the variable intake. Nissan motors are insane, they're built incredibly durable, so using the motor you have now isn't such a bad idea.

 

Well i've sprung a small oil leak i'm trying to trace it. BUt more than likely i will be doing a 35 swap and keeping it na i wanna put my 4th gen in the 11 and maybe power from 300-400 not 100%

 

A VQ35 NA wont do 11's, unless you really really lighten the maxima, to the point that its a drag only car or really uncomfortable.

close to 300 hp is possible, look on my350z.com. but for 300 wheel HP to 400 Wheel HP you need a turbo, and a VQ30 turbo can do that easily.

Boost the 3.0. If you want to stay NA then 3.5
The 3.0 make great power boosted and will impress you.
I am 3.0 boosted and making in the 350's and is very fun to drive.
With a small amount of work & money you can get 300 hp pretty easy.

 

boost the 3.0

 

Latinmax... I have a 2000 SE. I want to boost my car to at least 350hp. You said it was a small amout of work and money... What are we talking about here? What are you runnin to get your 350hp? Cost?... if you don't mind.

Any info would be appreciated

Thanks
Chris

 

OK here it goes.
You need the SC setup with a min 2.875" pulley, larger injectors 510cc, Walboro FP
You could get away with a S-AFC to manage the fuel.

Now, to be safe I think (and I have) you should run eManage, J&S and water/alchohol injection.
Do a little research and you will see that it can be done but it all depends on how safe you want to be.... blown motors are not cheap.

 

Thanks Latinmax, I appreciate the info. I do want to be safe... . I will continue to look into this.

Chris

 

check your PM

 

Thanks! Latinmax,

I didn't get the pm here, but I did get an emailed copy of it. Weird, I guess it's because I have less than 15 posts.

Anyway, as I get a little closer I will definately get in touch with you. Right now I am waiting for the rest of my suspension mods to come in.

Thannks again
Chris

 

with the dek is it direct drop in no changes from the 97 vq30. Now the dek has the 00vi. I like the option the vq35 and the vq30 boosted but i'm not sure which route to go yet. So please help.

 

i'll be one of the first to say BOOST THE 3.5. You WILL want to supercharge this car, and you can definitely lay into the throttle. Wheelspin is always an issue, but just get better tires. N/A a 3.5L can hang with/overtake an S/C'ed 3.0, so you'd definitely be looking at a low 12's timeslip with an s/c'ed 3.5L with a mild tune, possibly 11's.

 

Maybe if the 3.0 has a stock SC setup & maybe (but I dought it), but never with a little smaller pulley. Besides a SC 3.5 is almost impossible to SC. There have only been a few that have tried and it has very difficult to get done. With may not getting it done.

I say boost the 3.0 and don't try to be a pioneer on doing someting that has not been proven. Boosted 3.0 have been done time after time and you can learn from everyone else's mistakes and experience.

 

My 96 SE has 163k miles, and I am building a turbo kit for it. Hell, it is just getting broken in good at this point.

 

Well i'm pondering on not going through the trouble of doing the 3.5 i cant get a clean write up to understand most of peoples write ups dont give full details and part details to show what you exactly need. But the other factor is a 3.0 is a direct drop but i'm curious if i use a stand alone on the dek will it be able to control the variable intake system? I am gonna go w/ the pfi kit on it. I'm wanting to go 11s with it on slicks and weigth reductions and 12s with streets, and high 12s and low 13s on low boost settings. That is the goal.
