ok i recently bought a T4 turbo and and all the flanges, manifold, bov, and front mount for my 90 rx7 gtu. the engine has 114K miles on it and i was just wandering if theres anything i should buy/do before hooking it up?

thanks, Kelly

 

what ecu is going to run it? what are you using for the engine wiring harness?

 

You're in big trouble.

You still need...
Turbo II transmission
Turbo II driveshaft
Turbo II rear end
Turbo II rear axles

Recommended...
Turbo II *ENGINE*

More recommended...
Stand-alone EMS

I hope you have several thousands dollars for this.

you'll need some tuning and a stronger clutch. and more fuel

 

still need ^^^^ .. alot... need to find another TII doner chassis... have you talked to anyone else here in oregon.... I live over in eugene.. can prolly help you out..

 

I already have a better clutch and kyb 4 adjusable struts. But why the T2 rear end and stuff you dont think it will last? And i just have the stock ECU and wiring harness right now. would the T2 ecu and wiring harness be a good idea? and what fuel injectors should i get?

 

Oh
My
God
...
Becky, look at her butt.
Oh wait, wrong place.

May I suggest you do a search for NA to turbo conversions?
Hell, I think it's covered in the FAQ in the stickies above at the top of the threads list?

one, please dont tell me it starts with ss and maby autocrome
two, no your na "stuff" wont hold up
your compression ratios are too high for forced induction
your stock ecu has no idea about the world of boost
your injectors are way way too small for the added stress
if your talking about a reman clutch or anything made to hold less then 200lb id look for a newer one
so, unless you ARE willing to do the work needed to convert it to a tII and then buy the extra stuff needed to run your turbo, i would say buy a running tII and make your way up from there, know that if you can find a tII in good running shape you'll still need: new clutch, 720 secondary injectors, turbo timer, boost controller, ether a piggy back or stand alone engine mannagement system (look at safc's or emanages) full exhaust, boost guage, fuel pump (look at walbro 255) think thats about it...you should probably ebay it and just spend the money else where, like i said, its alot harder with a na then with a turbo, but to use that your looking at spending several times what that turbo costed

 

hahahhaha, gotta love mr teds comments huh?

The NA tranny/diff will hold, but for how long, no one knows. One guy back in the summer running an na with turbo just broke his tranny after a year of normal non spirited driving.

Me, im keeping the na ****, just to see. I know its gonna slip and suck, but im just gonna try it out anyways. In the end tho, I will be using the TII tranny, clutch, pressure plate and flywheel, I'll buy the driveshaft from mazdatrix so I can keep my rear end. It'll be interesting to see how things unfold to say the least.

 

Since when?

True, but that can be worked around.

Yep.

Yep.

Yep...

 

I already have the walbro 255 fuel pump and and full exhaust and i have some kind of stage 3 clutch. But where can i find new injectors at? I was already planning on getting the T2 tranny but i wanted to wait till i got my street port and rebiuld my engine. And what should i do about my ECU then? could i swap one from a T2 or would it be easier to work around it?

thanks for the help guys

 

Kelly...you need to get a stand alone EMS...it replaces the ECU, runs off of a laptop, and tells your car how to handle the turbo. You will need at least 720 cc injectors. Your tranny is gonna go KABOOM before long. Theres ALOT of other little things you need too. Not to sound like a jerk, but did you actually think you could strap a turbo on an N/A engine and it would just work? You have to modify the cars mechanicals and electronics to allow it to know how to use the turbo. Unless you don't mind spending another $3k-$4k, then sell the turbo kit on ebay. If you want cheap power get a wet nitrous kit. And this time, read up on it before you jump into a project.

You NEED to read the FAQ on this. There is *lots* of NA-turbo info out there, most of which is from me.

 

sorry about that, i didnt think when i posted that. (it was 4:30 this morning) i ment to say the compression ratios are too high to run high levels of boost.

 

OK i wont need a stand alone EMS. Ill just get a SAFC witch is way cheeper and way easier to use. And i kinda figured i needed bigger injector i just dont know where to get some at? and i know i can do it all for under 3K

 

www.greddy.com
click on engine, to the left under cooling and then injectors at the bottom of the page, 720's
have at it hoss

 

If i swaped the T2 tranny would i have to fab the drive shaft or anything like that and should i get the T2 diff also?

 

You'll want the TII rear end to handle the torque increase if you start to boost alot more. If you want use a TII transmission you may need the starter also and then a custom driveshaft or purchase the one from mazdatrix (http://www.mazdatrix.com TII to NA).

 

How much torque are we talking here? I've seen NA guys running 250 (some guys higher on P-Port engines) still using the stock NA drive train. While I'll agree that the T2 stuff is obviously stronger. Does anyone KNOW what it takes to break the NA stuff?

 

Is it safe to run 5psi on my stock electronics untill i get my fuel manigement

 

Lets see....
You have 460 hi impedance injectors, a upgraded fuel pump, and a high compression motor...

Umm no until you get the larger injectors, SAFCII, and something to hold the power.

And it has been proven by kevin landers the NA drive train will not hold up to a turbo motors power. Just search for more info on the topic.

How exactly do you plan to turbo your NA motor? Do you have the turbo motor intakes? Or are you just going to try and make it fit?

Honestly, dont do it right now, research more, alot more, no offense but you obviously dont know what your getting yourself into. And we dont want you to blow your motor!

 

Are those torque numbers?
