Hey Guys, here is my Project
 

i have a 91 white b package with 107k on it.

it currently has sway bars, springs, fm rear a arm brace, strut tower bar, light weight fly wheel, and an rx7 afm.

what is on the way is a cast turbo manifold and intercooler off flea bay, i am going to use a 3000gt tdo4 rebuilt with a shaft upgrade.

what i still need to get is injectors from one of the various car injectors we can use, fpr, and an oil feed line.

once all is said and done and hooked up i will post pics and videos on youtube

hopefully all goes well and the stock rear end holds up until i can go rx7 lsd and the stock clutch holds up until i can get a stage 3.

i was wondering do you think the 3000gt tdo4 is a good choice? my friends car spools 2 turbos at 2300 rpms with 3.0 displacement so theoretically i will spool 1 around 2200rpms, i only want 5psi for now and this turbo seems optimal, has anyone else used one?

its a teeny lil turbo, so it will die off up top. if you're ok with that then go for it

Never ever build a turbo kit around a single piece.

Sell the turbo and start fresh.

Good luck bolting a td04 housing to a t3 flange. Let us know how that goes.

As Rider said, unless you are familiar enough with turbo setups and you get an awesome deal on a part that you just happen to have laying around: NEVER base a build around 1 specific part if it doesn't match exactly what you want.

The TD04 is a bit small. You really might want to re-think it.

its a free turbo thats the main selling point on it and i want low boost for now, later on when work picks up i am going to do a whole tear down and build the car as much as i can.

one question though that popped up in my noggin is if i tweak the waste gate open will it still spool? i know i cant hold 7psi which is factory pressure but if i could i would :/

You are making every single rookie mistake there is to make, and completely ignoring logical advice. On top of that you know so little about turbocharging that you don't even know how a iwg operates.

Good luck with your build. I'm sure it will be a great one lol

see all post history for user medic.4life on this forum.

If it's a 7psi wastegate you can't make it open any sooner. And for the love of everything good in this world, please rethink your turbo build. Get proper engine management, buy a different turbo (seriously, chinachargers are cheap and do the job), and get a wideband oxygen sensor. I see you are buying an FPR, but you have nothing to control those bigger injectors. Please don't tell me you plan on opening up the rx-7 afm and playing with it until it works...

I made the mistake of building a turbo setup around a single part twice (wasn't on this board at the time) and I regretted it so bad. Finally just said screw it and ordered all the proper stuff - AEM EMS, flyin miata DIY manifold and DP, godspeed turbo, wideband o2. It was the best thing I did.

you wont even need injector for 5 psi.

newbie insight
 

Yeah right... :bowrofl:

Lost count how many times I have read that same sentence on every newbie who plans to go turbo. :loser:

These guys are being pretty polite compared to usual.

so...
You wont get a manifold for it,
Its too small, rather than spend time and money rebuilding it just buy a china charger, one the right size,
You need management BEFORE a turbo, INCLUDING a wideband, EVERY time.

My build is lame but is working for now. If I could go back and do it the way that these guys are recommending I would. Do some more research before you buy any more parts.

Some people learn by reading, some learn by doing.

Let this guy fuck up and learn his lesson. It's his money, he can waste it if he wants.

I learned my lesson...twice LOL

If your going for low cost just pickup a sr20 t25 or t28

I have a TD04 on my WRX, I am boosing 18.5 PSI and it starts to spool before 2,800 RPM. I dont see whats not to like. It is inexpensive, and readily available off WRX motors.

Build the car the right way the first time. I stuck a motor in my car because I thought I could do it cheaply. I have kept it as cheap as it gets but I also just bought a new turbo, AEM FIC, and have to redo my inter cooler piping because I am changing everything. I was trying to be super cheap and easy but it never works. Buy some management doesn't need to be megasqurt but something adequate, get a wide band and get a t25,t28,t3 turbo of some sort it will save you tons of time and money down the road. You can do it how ever you like but if you half ass it you will be right here next year fixing all the shit and hating your car. If you happen to make it through all that and still keep the car once it is done right you will never look back.

I was just thinking of doing the same thing as this guy! Glad I checked here first! However what I dont understand is how these turbos feed a 2.0 wrx?

:inout:

+1 ;)

Everyone is different in the path they take but if I may add my :2cents: this is how I look at it for the OP.

1. Install an ems.

2. Build the bottom end first with forged pistons and rods, that may seem like overkill for ones initial hp goal but hp is just as addicting as crack and soon or later you will want more. Building a proper bottom end is like that commercial that says "Set it and forget it".

3. How do you know you only want 5psi and you should not be basing your decision upon a completely different vehicles dynamics. I feel that a person who wants to turbocharge any engine should base their path on the future and the hp they want.

The members here KNOW what they are talking about and you would be wise to listen to them! I always stress the importance of finding a shop you can trust, who does quality work and can coach you each step of the way and is a tuner of the ems you decide to go with.

If you build 'on a budget' like most of us do you would be smart to listen and learn, the only person you need to impress is yourself.
