I recently owned a 90 gsx. I keep on breaking awd trannys. brook 5 trannys in about 4 months time. just because of worn out clutch essembly.the short version tunning a friends dsm, he gave me the car for payment. and know I am swapping my engine it to the mirage. I'm about 90% done. gsx made 412 off of 23 psi between me and you I run between 27=28 lbs. heres my mod list.

turbo hx35
bulls eye housing
dsm link
gm mass translator
lc1 wide band
hks 272's
2 1/2" exhaust
680 injectors
performance fuel pressure regulator
2600 act
3 bar map
turbonetics old dealt gate
stock internal six bolt
stock head gasket
stock head studs
compression still coming up 140 across the board

I tune everything myself, I didn't have help from anybody.air fuel ratio between 10.5 and 11.I believe thats what make my engine last. just gives me rooms for mistake. I also use 110 octane.hoping for about 500hp when I am finished.

I have a 75 shoot nitous kit but have never used it. maybe just alittle later on to experiment with if I turn the boost down to 18. already at stock engine breaking point with out nitrous.

Getting a 3" exhaust system installed for the Colt swap? You made that much power on a 2.5" system?

With that HX35 you're still going to be building tranny's !!


Best of luck with the swap!

yes I made that much on busher manderal bent 6 yr old 2.5 exhaust. only reason I did the 2.5 is because my 98 eagle talon had a lot of bust creep on t25 with three inch turbo back exhaust. but on 14b don't think I would have had the same problem. oh well to late now.



mainly had tranny issues because of worn out clutch assembely. it is like shifting gears with your foot half way on the clutch every time you shift.=broken second gear fork. hope I don't have that problem with the colt.

On the csm's, the clutch pedal is durectly coupled to the master cylinder, unlike dsms, so you should not have to worry about that. Good luck with the project.

what's up everybody I don't think I have ever put pics of my cars up. so I wanted to post some now.oh yah and I found an original turbo mirage. paid 1,200 for it interior is in good conditin and out side is pretty good to.engine in turbo mirage runs but not like it should. got it home through a 14b on it and side mount, 450cc injector in about three days of having it. oh yah had to put my dsm link ecu in it. because the ecu was missing.problem could be valve guides. thinking about swapping my motor from the colt to the mirage. if I could sell the colt (ready for swap), intercooler,original turbo mirage wire harness and turbo mirage tranny included. all you would need is a complete engine, dsm ecu, exhaust system from turbo back, and first gen mass. if anybody is interested let me know. I want to sell it for $600.00. if you want me to do the work I can for a total of $700.00. you bring everything you need. come on guys it even comes with new tach. hahaha. anybody who is interested let me know. rim show in pics not going with car. rims on turbo mirage will go with the colt.

You could pick up quite a bit of power if you leaned it out some. Those air/fuels are way too rich for 110 octane. I'd be tuning for 11.5:1, and that's still pretty conservative.

11.0 to 11.5 is fine depending on what you are tunning with. you might see a hp increase from stock ecu and from 650 injectors and above. because when you lean it out with an afc, you might be changing your air flow signal there fore changing you timing maps. but from 11.0 to 11.5 I saw maybe an 8-11 hp increase. but the real power came in with, changing the timing with dsm link. not trying to come off as to tell everyone how to tune this is just how it works for me. 11.0 just seems to keep knock down in the next gear. there for getting more advance and making more power.



as for the rims I am not sure what they are everybody seems to like them...... but I hate them...

What timing numbers do you tune for?

yeah really. 12.:1 to 12.5:1 afr, 23-24 degrees of timing and 30psi falling to 23ish on the 16g and there was little to no knock. Seems like you could really push some more out of 110.

LOL I just noticed the ricer piece of shit on the road in the picture with the red colt.

right now I am running, 24 degress up top. and about 11.5 afr with c-16. holding ethier 27 psi or 32psi. where ever I set it it stays tell redline. I don't know. it could be my small intercooler, that gives me knock. as mentioned up top on that setting I do not see knock. by the way what are you guys using to look at your timming?


yah I noticed the honda in the back round to.....

It could be knocking because it's running so bloddy rich. If you're on C-16 you have to run the car leeeeeannn, we're talking like 12.5:1 on that gas, otherwise the car won't run at its full potential. 11.5:1 is a good a/f ratio for 110 octane gas though, or like C-12 or something.

I wouldn't tune cam2 (sunoco 110) to anything below 11.3:1 except for maybe peak torque, but I still wouldn't dip into the 10s there. Getting c16 to knock means you are doing something wrong, seriously wrong. I might lean c16 out a little more topend compared to cam2, but probably not. I'd just turn the boost up more with the c16 and run more timing during spool up and in the midrange.

Where does the car knock at on the c16? Also, I need a timing log to help you out.
