I have an 88 turbo with just a few basic mods including a large intercooler with 2.5 piping and 3 inch exhaust. Nothing else majorly different. But at WOT It builds 10psi then as rpms increase the boost decreases until it settles at ~7psi. Could it be possible that I've already maxed the turbo...

My 88 Turbo is jumping a little under light loads. Is 100% replicable with quick drive and is consistent. It happens at less than about 5-10 % throttle. Cars idles fine. Car runs fine at more than 5-10% throttle. Boosts fine and reliably at 10psi. Gets expected gas mileage. Has no codes. IAC is...

I have an 88 turbo and it just started running super lean the other day. I have the regular gauge, so obviously I can only say really lean instead of a certain a/f ratio. However everything on this engine is new, it holds perfect fuel pressure, the afm is new and good, and I have a knock code...

When I upped the boost on my 88 turbo I started hearing a solid ding very very similar to the "key in ignition, door open" alarm. It comes on when the boost gauge reads about 7 or higher and stops when I let out. Only does it when I pass 7 lbs of boost. Do the mk3's have a warning alarm?

Hey I'm slightly new to supras and slightly new to the forums and was wondering how to see peoples mods lists and or if someone could give me a mod list and a horsepower/ torque rating. I would really appreciate it. I have a supra that I want to build but am not sure what all to do. Money is not...

So I have code 52. Yes That one. And yes I have looked and search first. but let me explain. I had code 52 so I bought two brand new sensors. Then wound up having to replace the engine so I got the only engine I could (GE). So now I have one knock sensor hole. So I tried some things...

I just got my GTE running and it idles smooth (too high but smooth), and runs smooth. However, when ever I get into boost it starts leaning out bad. It pulls strong but then it start to gets weak when the turbo start spooling. I haven't been able to figure it out. Mods: Intercooler kit 3...

Hey Guys, I have an '88 Supra Turbo Targa with almost all of the options including the factory installed alarm (if that's not standard). Well the problem is that the alarm randomly goes off. I lock the car and it will be quiet for a while but then at some unsuspecting moment the alarm starts...

I was getting code 32 and replaced the AFM and did not have the code anymore. I went for a test drive and it was fine until I pushed the gas. It came back as soon as I got into enough for a shift and started acting like it wanted to choke again. I am not sure what to do.

I have rewired my knock sensors with 100 percent shielded cable and replace both knock sensors with brand new. I am still getting the code and do not know what to do to fix it.

I'm hitting fuel cut on my car. It is jumpy then cuts off whenever I put my foot down more than 1/4 way or go over 3000 rpm's. If I don't try to push though it takes off as if it is floored. It also has hesitation in the throttle. It likes to act like it wants to die first then take off. Mods...

I drive an MA70 Turbo and I had a quick question. Does anyone else have a problem with their fuel pump overheating and losing pressure constantly? My stick replacement pump does this. I understand it is having a hard time keeping up with the fuel demands of the engine (which has been modified)...
