Hey guys I figured since threads like "How can I turbo my NA" pop up so much I might aswell give you the specs on the manifold adapter.
OK first you need 2 racing beat exhaust flanges $30 each, and then take them to a muffler shop or someplace that welds.
Next tell them you need the 2 flanges spaced out with 2 pipes to exactly 2.5 inches "very important any more or any less it wont fit and hit the body or lower intake manifold.
And well thats about it, all you need after that is a stock T2 turbo and manifold and bolt it all on and have yourself a turbo car
BTW you guys will also need oil feed and drain lines but you can figure that out easily.
See ya
Hope this helps a few people

 

Yep, well, Thanks a lot, saved me trial and error!!
I am getting the parts together for the turbo kit now, I already have the fuel pump, injectors, and I am getting an A/F meter, and S-AFC immediately.
Should be a screamer considering I am already running low 14's N/A.


Just a question- Does anyone notice more turbo lag with a FMIC compared to the stock mounted one considering the massive increase in
volume in piping and I.C. compared to the stock unit????

 

May I ask your MPH down the 1320's? I just want to compare them to the Honda Si.

 

well you can't fit a stock one on anyways so it isn't going to make much difference... if you get a normal size core and use smaller piping the lag will be fine. you can't run much boost anyways so you don't need a big one.

 

YA like Scott 89T2 said, you cannot run a T2 intercooler on top
of your NA motor.
But you can get a starion intercooler and mount it up front and just make your own intercooler pipimg, not very hard to do.
Also when I used to have the kit on my NA motor there was really no lag time at all, full 10psi came on at around 2,500 and dropped of to about 8psi at 8,000rpm's.
Also I suggest that you not waste your money on a A/F gauge and instead get a EGT gauge wich will tell you how lean your car is really running

 

What sisze piping would be recommended for a FMIC running no more than 10PSI MAX? (I have high comp motors)
I guess I could run the compression down a bit by trickling sand down the intake while it's running though.... (dauugh... OK!.. hauyuck...)

 

what do u think the estimated price would be for this convertion???

 

now is that 2.5in of space between the flanges? Or is that 2.5in measured from the outer edges of the flanges??

 

Outer edge.

Mazdatrix also has the same flanges, for half the price.

 

hey thanks!

 

You could probably get away with doing it for about $600 not counting intercooler or maybe even less if you find some deals.

 

Hey VtekEater, I am in the middle of the conversion right now, sort of my own style, all the info will be up in the next few omnths when it's done.
But I have to say to everyone, that price seems nice, but that's bare bones!!! You get what you pay for, and as EVERYONE on this forum who has tried to cut corners (EG EXHAUST?!) knows; *You get what you pay for*- Do it once and do it right. I hate to hear people all bummed out because their $500 engine rebuild puked in a year, when for an extra few hundred it could last you for many more years. I know budgets can be tight, (I am a university student living on his own, and should even own a car!) But in the long run, a few extra buck now can pay off in spades later.

The odds and ends to do the conversion cleanly and properly do add up a bit, but it still shouldn't cost very much at all considering the HP increase you will get!

 

This needs to be Archived when it's done!

 

Hey Bambam are you going to use the stock T2 turbo and manifold right??

 

VtekEater-
Ya, I am using the stock 89-91 turbo and manifold. I don't even have the turbo yet, but I am getting a manifold and turbo from a place in texas that I seem to have lost the name for... They had a 88 turbo on Ebay about a month back, and they have several 90 turbos and manifolds in stock that they sell for 300 bucks combined, not too bad.
I have the TII fuel pump, TII injectors, there are always intercoolers for cheap on ebay- I will be getting one soon, I'm bidding on an S-AFC right now, and have a dual gauge pod with boost and A/F ratio, so all I actually have to get is the turbo/manifold, and IC. (plus hardware for oil lines, etc)
I see you use the hitachi turbo when you made your kit, I am assuming thats different from the stock unit- what made you go that route?

 

So..after you have the turbo on, and all the plumbing done.. what do you do about fuel? Does the t2 computer work on such a setup?

-Tesla

 

No the hitachi one is a stock unit.
And as for the fuel I was using an FMU, T2 secondaries and a SAFC to bump it up a bit when boost kicked in, and never had a problem at 10psi for over a year.
But now recently I got a T2 motor with a T04 and haltech, and I blew it up like 2 weeks ago

 

Only T2 secondaries?
You didn't have a problem before 3800 rpm's with leanout?
I'm suprised, considering the turbo'd engine is basically the same output (at least!) as a TII engine, using 550 cc primaries...
I would use 550 cc all around just so I wouldn't be worried about maxing out the duty cycle in the injectors.

 

is there any chance (if this is really stupid question, sorry ;o) to use TII ECU, harness, injectors, turbo and intake (with IC) on NA motor ?

I have NA motor, ECU and harness in my TII, but i have complete running TII motor sitting in garage....i`m asking this question just to avoid engine swap (if its possible just change stuff on NA block...)

thanks

 

No you wouldnt be able to because the N/A block has six ports on it and the T2 motor has only 4.
BTW how come everyone thinks to turbo their N/A they need the T2 ECU?? It wont do anything at all if you swap em, hell I'm pretty sure it wont even work.
Oh and as for my injectors they where running at 78% duty cycle, when the boost started coming on.

 

The way I'm handling fuel is to use TII injectors all the way around, and then tuning them in with an S-AFC. It's the expensive way to go, but the most versitile...

If anyone cares, here's what I'm doing:
-88 TII turbo and manifold from 10AE w/ported wastegate (VERY important on 86-88 turbos)
-VtekEater style adapter w/smog fittings
-Stock TII intercooler converted to front mount
-Some type of BOV (Greddy TYPE-S or the like)
-Custom downpipe to Bonez Cat w/O2 Sensor fittings
-TII injectors
-TII fuel pump?
-S-AFC
-Coolent tapped from upper and lower heater hose
-Oil from nipple added to oil cooler, draining to nipple installed on oil pan
-AutoMeter boost gauge

Currently, I am waiting for next week to order some parts from Mazdatrix, and in the meantime, removing my oil cooler to have it repaired and a nipple added, and soaking down teh stock manifold bolts with penetrating lube for about a week...

 

You would want to do the swap anyway, the TII engine can handle more boost since it has lower compression rotors.

 

false statement, i have seen 28psi on a factory 12a with high compression rotors, factory apex seals and t04 60-1 turbo. as long as it ain't too lean or too rich it won't blow!

 

i would like to go EASY way and engine swap seems to be more difficult than just intake/and other **** swap......

 

Hey Aaron it looks like youve planned ahead wich is good, but
maybe you should tap the oil feed line from the oil pressure sending unit wich might be easier.
Also get an EGT gauge with all that stuff as well, so youll be able to tell if your running lean or not.
And now with all the stuff you have even more than I did your looking at easy 13's man
Good luck, and dont get boost fever
BTW what type of smog fittings are there??? Don't really remember any on the stock N/A manifold.
