X90 Turbo Upgrade Options
Posted 04 August 2011 - 08:01 AM
Stock twins rebuilt with steel wheels and increased airflow by Driftmotion?
Used HKS GT2835 (aka GT3071) or GT3037 (aka GT3076) kit off of Yahoo Auctions Japan?
Buy cheap turbo manifold and have wastegate piping modified to fit?
Buy cheap turbo manifold, block off external wastegate pipe and run an internally wastegated turbo?
I plan to run 440cc injectors and a PowerFC. My end goal is just under 400 HP since that's what my Exedy Hyper Single is rated at.

I have a friend who owns a shop and he is a skilled welder/fabricator. I have no doubt he could modify the wastegate piping and reinforce an aftermarket turbo manifold for a reasonable price.
I updated the OP. I'd like to get just under 400 HP. 380 sounds like a nice round number.

this thread is evidence that some people at jzxp still do it right.
1. if you dont have progress, dont post about your car.
2. if you're not posting about your car, shit all over everyone else.

It's not on the website. You'd have to call them about it.

The key is the dump pipe. If you want to run high boost through the twins, then this needs to be upgraded. The standard one holds too much heat, and is usually the cause of most turbo failures for the twins. Dude here in Perth had custom dump on standard twins (ceramic), pushing 18psi for 3 years, making 340rwhp on his drift car. Recently took the the motor out and the turbos only had minimal shaft play.
I don't know about the Driftmotion ones, being Australian, but steel wheels generally flow around 20psi happily. I'll probably only run 18psi, but i wouldn't of expected anything near 384rwhp. That's a lovely figure.

I didn't really think about the dump, Skitzo. Thanks for bringing it up.
It looks like either way I'm gonna need some fab work done to the exhaust, so I might as well go single turbo. Not to mention, having DM rebuild/high flow my twins would probably cost as much or more than their single kit. I'm sure the DM kit is awesome, but kinda pricey for me considering it's not a complete kit and will need fab work (no BOV, intercooler piping, etc...)
I know a lot of folks don't like when drivers use eBay/knockoff parts, especially on a "JDM tyte, yo!" car LOL, but it's the most cost effective and if the cheap turbo blows I can just buy a new one for well... cheap. It'll also give me the opportunity to try out different turbos.
Used kits do go for cheap on Yahoo auctions, but availability and condition can be an issue. I'd hate to get a used HKS kit and there be parts missing or the turbo be blown.

get your manifold and shit like that there, and then find a proper holset or hunt for a cheap GT.
Thats cool you feel like you can make a 7m proper. Just do it somewhere else. Around here we call that shit gay.

My budget for the setup is ~$1500, which should be plenty considering I already have the PFC, injectors, and fuel pump. BTW, I'm using the fuel pump from an R33 GT-R because I've seen a lot of JZX chassis in Japan running them.

The kit isn't bad and has pretty much most of the stuff you need
You can always send a message to the XS Power dude and tell him what you need, he's open to making custom kits.

I have an awesome tow rig now, so I'm no longer worried about getting stranded at an event.

FYI, i just purchased these dumps to run with steel wheel turbos. Much better flow which will help with heat dissipation.
