Very nice job! Perhaps we can put together a thread with information on ct-26 identification and differences? I wonder what the gain from the ct26A is over a normal ct26.
Do you still have the computer to that engine?

the engine i pulled out of the car was running on a regular 7mgte ecm i have come to the conclusion that is probably the reason it blew up. the ct26-A on the 7mgte-u only made an extra 12hp or so at the same boost level but from what i understand the turbo is capable of flowing alot more exhuast than the ct26 allowing around 17-18psi before i becomes completely useless unlike the ct26 which becomes basically useless at around 14-15psi
I havent been able to find any compressor maps but i'm gonna do some dyno pulls soon and ill do a baseline pull with just a fmic and 3 inch turbo back as far as engine mods. then i'll up the boost to around 10-12psi and get some realistic numbers.

off topic question though, if my fuel pump is wired straight to my ignition will the ecm still allow fuel cut through injector signal or will it just go lean?

I think it cuts off injector pulse but I'm not 100% sure. Were you able to check the timing or codes?

yeah i put in some spades so i can just plug in the fumper to check my timing but as far as codes go im not concerned with it i only have injectors, tps, cps, kvafm, oil psi, coolant, and 02 hooked up so i'll always have like 10 codes stored
