Single Turbo?

[andymac40330]

I have had a 1990 Nissan 300ZX N/A (non turbo) for about a year now and i was wondering if i could do a single larger turbo conversion for less than the twins or if it would be about the same or what? I am on a limited budget so price is a big factor. If it is possible could anybody tell me what parts i would need and where to find them? Also would any turbo kits for other vehicles fit my car with little to no modification? Thanks

Ther is no point to do a single turbo. Also, basically, since you have an NA, you must do a full on Twin Turbo conversion if you want boost. People have boosted NA motors, but I find it silly b/c the gains are little since you can't run high boost and the price is not that much better.

My apologies on my sig I will fix it tonight.

Here you go, I shrunk it down alittle, that things huge.

I'd just stick with Twin turbos, but if thats not in your budget you could make a decent amount of power with the car being NA.

Id really like arond 300-350 HP. What exactly would you recommend doing to it while its a NA, or what parts are actually NECESSARY to do the NA to twin turbo conversion? Thanks

Use the search button, there are more than a few topics on this matter

[evildky]

you can meet your gioal with the basic TT conversion, intake,m exhaust, boostjets or other boost controller and remapped ECU, you shouls be a bit north of 350whp

If money is an object, a custom setup single turbo isn't the way to go. Getting a TT front clip and going with the VG30DETT is your answer.

Hello new to the forum. I have a 1990 300zx N/A and have been able to modify my car in order to have a rear mounted turbo installed underneath where the spare tire wheel well used to be. I've used a T3 RB20 turbo at 5psi with an internal waste gate and BOV. I have less then $800 into it and every part is new including the turbo purchased off of ebay for $239, oil pump for $99, y pipe for $20, T3 flange adapter for $30, 8 feet of 2 inch exhaust tubing $45 Bov used ebay $25 and $140 paid to the exhaust to be welded and bent properly. $50 worth of brake lines, adapters, clamps, vacume lines and fittings. $10 for radiator hose, and $35 boost gauge. $100 for high volume fuel pump. Bascically I removed the two mufflers from the cat placed 2 s bend pipe in their places that led into a y pipe. The single outlet side has a t3 flange welded at a 45 degree angle to which I bolted the turbo. The pressurised side is fed to the front of the car using 2 inch exhaust tubing with to l bends that eventually get tied into the air mass sensore. the exhaust side as a 3 in l exhaust pipe that acts as the exhaust tip. No need for muffler because the turbo quiets it down. I'm currently running 5-6 psi and it makes a huge difference. Sounds like a jet plane when launching and hard accelerating. Under normal driving it kicks in around 3200 rpm . believe it can be done. I'll forward pictures if you want to see.

^ Welcome to NICO, sounds like quite the project you've got there. Post up some pictures and if yo9u can, dyno results

[gpelite]

dyno slips would be awesome! very curious

I could not disagree more, my single rear mount turbo has made a huge difference in my cars temperment. What's even better that the set up is so very stealth under normal driving , then just breaks all out when you throttle up aggressively, sounds like a jet taking off I have pics under the thread rear mount turbo on the z32 forum

Hi, I am thinking of doing the same modification to my 300ZX NA 2 + 2. If possible can you please forward me some pictures of your setup. I hope you can also answer some question for me if I come across a few bumps in the road along the way.

[DizzyDe32Z]

Ive been thinking almost the same layout. Now did you have to have your ECU remaped or replaced?

I feel like I've seen this car before on the Book of Face....

Really? So how does the motor know if its a twin or single setup? The stocker will be fine to 6-7psi. Call Reed at Work Turbos and discuss it with him.
Twins are much more expensive.

Personally I dont like rear mounted setups. Turbos need heat. I was able to fit a 4788 in my 300 with a small block chevy, so room for a smaller turbo and the stock motor should not be an issue. Plan things out well and you will be ok. You will need injectors and a GOOD tune though.

Building a forged rotating assembly and running 20-30 psi will just destroy the driveline and twist the car up.

I just went to the thread that discusses the Vilmenay's build and on page 3 or 4, there is another guy who just bought the car off of him because he blew his motor. Not sure this setup is what you want.

[addicted4life]

Mitch @ EPRacing can make custom manifolds for your single, or any type for that matter. Man is a genius. Better have deep pockets though, for his quality you pay.

Single turbo? Might as well get a turbo Z31. Should be less of a headache... lol

Only single turbo that I have seen online that was successful for the Z32. Awesome car. Extremely Modified as well.

[z32loverboy]

Yeah that car is sick. But I guarantee those horse power goals could've been reached for cheaper going twin turbo. It's possible to do, that hasn't been in question. It's the practicality of that whole shebang.
