would i be able to do a fmic with the stock ecu (i know silly question).

what is this fuel cut defender?

A Megasquirt isn't that expensive, even pre-assembled.

the ECU cuts fuel to the motor when boost gets too high. THis little electronic box tricks the ECU into tthinking boost hasn't increased as much and allows you to dump more fuel and turn the boost up (either manualy or with an electronic boost controller).

I've never done or looked into the swap into the first gen but the body electrical harness won't mate up to the ECU so you may have to rewire some things (this is based on an S4 car with S5 motor and ECU and i assume it's the same issue for the first gen).


FMIC on Stock ECU is fine.

the wiring wount be a big deal. my buddy iam building the capri with went to uti for wiring.

can i use the fornt cover from my 12a or would i need to find one from GSL-SE. i belive i was told in the past the 12a will work.

with the wiring i dont mind having to run after market gauges iam all ready am for water and oil temp any ways. i was told my cluster speed cable can be hooked right in to the TII trans with no problem.

what is the deal with the wiring. would i just need to run wires to the ecu so it gets power and thats it?

You should just use it like that, then. There is no sense in changing it to carbed, you're only adding expense.

AFAIK, you would need a GSL-SE front cover, and it needs to be tapped for an oil return line for the turbo.

thats no big deal for me taping holes, iam a machinist after all / welder lol.

well its time for me to start putting money aside.

if i deiced to rebuild my 12a and turbo it would you all agree that a TII trans would be the best band for my buck, since i know theres a chance of blowing the stock 12a trans up.

you mite all be asking you self i thought he deiced on a 13bTII swap. well i found out family member can get me a rebuilt TII trans dirt cheap and a few of my TII friends are upgrading there turbos and offered me there old ones for all most free. which made me start doing alot of math. i could rebuild my 12a , get a new TII trans, and all the turbo parts need for less then the cost of the TII motor packages i have found that would need a rebuild any way.

What year is your car? The S2 trannies are pretty beefy. If you've got one of those, I wouldn't bother upgrading unless you're planning on making over 300 HP and have real sticky tires and a grabby clutch, and at that point you should be looking at upgrading the rear end as well. To me, a bigger benefit of the TII tranny is that it allows you to use 240mm clutch components.

my car is a 1980 sa. at a cost stand point a turbo 12a would be my best bang for the buck. i probably wouldn't go more then 10 psi max. i was told 8 to 10 psi is safe to run on a 12a(motor) thats not a 12at.but people have run higher boost. also id be useing a o.e.r setup with the rotary shack intake. any ideas how much power that would make. would my stock trans take it if i rebuild it or should i look for another. what would you recommend.

i am not trying to build drag car or any thing like that so i dont care about big hp number. i am not going to be doing burn outs or hard launches. i daily drive this car during the summer so i dont beat on it as is any ways. i am mainly looking for a bit more power.

The amount of power you'll be making depends on a number of factors, most particularly what turbo you use and whether it will be intercooled. But I personally wouldn't bother swapping trannies. As long as you're not abusing it, it should be fine.

(On the other hand, blowing a tranny isn't particularly scary to me, so if it is to you, take what I say with a grain of salt. :))

i've all ways been confused when it comes to turbo sizes. i was thinking of runing a stock second gen turbo.
