    Re: 79 RWD 2.5 Colt

    50 trim turbonetics to start and get it all running and road worthy, I have a t67 garret I am going to try on it later, probably have to get it going with a little bottle im thinking?
    Probably... what exhaust wheel and housing is it? I have a t67 with a .96 a/r and p-trim wheel, i dont think it would EVER spool on any 2.5 i own. I know they make put much smaller housings on some of them.

    Dont push the red button.You hear me?

    Re: 79 RWD 2.5 Colt

    ok so yours is a t3 turbine side with a stg5 wheel and you have a .63 housing for it. That's going to be tough on that engine but the loose converter will help. What was the spool like on the 2.4L?

    The upside is it will make as much power as you'll probably ever want to.

    Re: 79 RWD 2.5 Colt

    With the .63 hot side on it it would start making boost at 2500, he ran 30 psi as max boost. I know it would suck as a street turbo on an 8 Valve but with the converter and tranny brake it would probably be ok(maybe?). He bought the .82 hotside for it, but hated how it lagged on the street. I probably will never use it for the steet, but my turbo is so easy to swap out that i am gonna try it at the strip once I get the car running and driving.

    I know the 50 trim turbo I have on the car is not the best one to have on it either....

    Re: 79 RWD 2.5 Colt

    If it spooled on the 2.4 that early, maybe it wont be too bad on yours. The 2.4 probably had a little higher compression and a little better flow, but probably not by much at that rpm. Id be interested to find out how it does on yours.

    As for the 50 trim, maybe its not the best, depends on your goals, but its definitely not bad! As long as its a stg2 or 3 turbine it ought to be a good all-arounder until you want to make 400+hp.

    Thats about what I figured, it is all the stuff from the cargo, that ran 13.17 in denver. With the better exhaust header and 4" plenum and full 3" exhaust, and 750+ less weight, 904 trans and converter and rwd it should be fun, I should be able to launch on a good amount of bottle also without crossing my fingers

    Re: 79 RWD 2.5 Colt

    I just realized i have an 87 dakota with a 3.9/auto in it that im thinking about 2.5 swapping, so let me know if you get some kind of adapter plates thing rolling. Id like to swap to 5spd but if the adapter plate is cheaper i'd definitely consider it.

    Re: 79 RWD 2.5 Colt

    My buddy has a bellhousing in his oval track car, small block mopar to t5 Mustang tranny, so really with my adapter you should be able to put that 5 speed behind a 2.2/2.5, just have to use a hemi/ 440+6 flywheel I think

    Re: 79 RWD 2.5 Colt

    the only 5spd swap id do would probably be the factory one, and even that is iffy.. i guess i just dont want the 5spd that bad unless i come across a parts truck for $200-300.. But if i could buy the 2.5 adapter for something reasonable id just go that way for simplicity, and that way my fiancee would not refuse to drive it too. hahah

    Re: 79 RWD 2.5 Colt

    lovin the colt! kinda wish ida turbo/4'd mine. i did a 360/727/8-3/4. had to stiffen up the suspension and fab subframe connectors (along with everything else) but it hooks awesome. didnt wanna cut it up,so i had the local spring shop make me an extra leaf for each side. that raised the rear enough to allow for 26x8.5-15's on draglights. no rub whatsoever. one of the front coils broke while i was trailering it to the muffler shop...so i pirated the struts off a later model z24 cavalier. filled the cartridges with fresh oil. i cut the lower spring mount off the cav strut,and welded it on top of the colt's. used the springs also. you'd have to see it leave to believe it. even with that heavy small block-it raises the front,plants the rear...and stays that way until i let off after it goes through the traps. i expect your traction to excellent with a lil effort.
    love the colts....just dont break that windshield! there aint one to be had anywhere!
    would love to show pics of mine...but they wont let me post pics for some reason.

    I think a burnout video would make us feel better.
