I've looked and I've read and I've read and I've looked. But couldn't find anything on it. I read in one of the stickies that by boosting our cars the power surpasses anything the nissan engineers would have dreamed of. My question to you guys is, what should be installed on the car before installing a turbo? Thus far I've figured new headers, y-pipe, exhaust, IM (00VI), TB and internals. Only thing is idk what kind of internals etc. Any help would be great guys. I just wanna make sure she can handle the power before I get a piston blown through the motor lol.

And I have a 4th gen with a SRI, budget ypipe which is 2.5 at the flex going into a custom 3in.

Thanks again guys

Compression and leak down test good way to start.

I could be wrong but I don't think there are any aftermarket internal options for the VQ30.

maxispeed

Well I know I've heard of people using rev up cams. And is it possible to use internals from a 300zxTT seeing as its a VQ or is that not possible cuz of it being RW?

I'm not sure if you can but you may not have to; from the info I've collected if you really wanna get new internals then the bottom-end should hold up. (then again, that's what I collected lol).

I've heard folks get the vq35 valves/rets/oil pump anf the cams you suggest if they were going to keep the vq30 and boost it. The 3.0's are pretty stout

Pistons and rods are availble for our cars, there not cheap though.

No, and its not a VQ.


Honestly, just boost it. Get a base setup going, once its done and your up and running then you can prepare to build it up based on the power levels your looking to achieve. You may find that your satisfied with the power being made by low boost and choose to just keep it that way.

Are they lower-compression types? I'm somewhat in the same boat as the OP, wanted to strengthen the bottom-end (and don't want to swap a 3.5 in)

no hijack lol

Flava_24/7

iTrader: (46)

Yes you can get lower compression pistons.
JE and CP make them.

I thought the 300zx had the same engine as ours just a RW set-up? or am i mistaking it for another car >.<

That doesnt sound like a bad idea. I just didnt wanna add boost and break a rod or blow something, you know? While were on the topic of breaking stuff, is it necessary to mess with the suspension other then your basic front and rear strut bar and sway bar, or would I need to do more to the suspention?

iTrader: (23)

You weren't joking, I just looked up the prices and no thanks lol. So just to reiterate the OP's point (and for my own reassurance) you'd say that a pretty decent running 3.0 could handle low boost for awhile?

Flava_24/7

iTrader: (46)

Yup, the majority of us boosted guys are running stock bottom ends.

you really dont need to have a bullit proof motor to go turbo. with the right tune you can put down 300+whp safely. VQ's are cheap so buy one as a spare and build it on the side then swap it over when you want crazy power.

people always think 300zx has the same motor as the 4th gen, they don't, its a VG30

maxispeed

^^^ is there another car with our engines? And how about the suspension? What should be upgraded there?

Flava_24/7

iTrader: (46)

Yeah, the 95-00 I30's.
Your suspesnion should be fine, you wont be making ungodly amounts of torque off the line so not much to worrk about there.

there are factory turbo VQ30DET's but they are overseas.

Okay that's very good to know, thanks gents.

I get twitchy about (I have a turbo dsm and the stock bottom-end was supposed to be good for 400hp and I still got it rebuilt w/ forged rods/pistons

I guess what makes me nervous is that, regardless of car, I get a little weary of boosting (or in my dsm's case bigger turbo) higher mileage engines, even on the stout 3.0.

QT you make a good point about building an engine on the side

OP, sorry for the full-blown (pun intended) hijack

maxispeed

^^^ no offence taken. It was still on topic so I dont mind. As long as you werent talking about the mole that just popped up on your back and your worried about it lol. So from what Im gathering, a stock motor and stock suspension should hold up, yes?

And i know this question has nothing to do with turbos, but i know ive heard of hondas doing it. They rotate the engine so the trans is on the opposite side, the reason they do it is cuz it creates a smooth curve for the manifold. would our cars benefit from this or is it just another 4 banger honda thing?

Allgood lol.

As far turning the engine it definitely sounds like a Honda thing lol (I wouldn't) Just my .02

There's a mole on my back???

I think the first question should be, how much power do you want. Like Flava said stock bottom end should be fine unless you want something ungodly. I really think its all in the tune. I have been running in the 400 whp range for about 4 years now with no problems.

maxispeed

Well I dont want anything crazy stupid, I heard anything over 400 horse for a FWD all your gunna be doing is burning tires and not really going anywhere (correct me if Im wrong, this is what I hear).

yeah thats where drag radials and suspension set ups come into play

1swtmax

Ummm, yea it smokes the tires pretty easy. All of first, second, third, then hooks up (highway). But at the track go with slicks and you should be fine.

maxispeed

What kind of suspension set ups?
