I also love the turbonetics T-66 BB turbo, Thats what Im looking for. I hear they spool there Butts off and the Exhaust housings arent Big at all.

Well Since Stock Pistons are 83mm and 84mm Pistons are .040 over then you need to find .060 overbore Pistons. Not for sure where you are going to find those and if you would even want to run them anyways as it would make your Cylinder walls really thin. Go with the .040 (84MM) Pistons and call...

Im originally from N.C. and Im retiring in 3 Years. Im never getting out of the Supra Business and Ive only been into the 82-86 7MGTE conversion for about 2 Years now. Ive done alot of these cars and there arent too many of them on the road these days running High 11s to Low 12s in the Quarter...

I had a Mitsubishi Heavy Equipment turbo that I was running on my Supra for a little while. Only problem I found with it was it had a turbine Housing of 17 cm and no one could tell me what it converted it in actual AR Specs. I made right at 500hp with it but I hated the Spool time. Set at 8 PSI...

Well, Went out and started the car up. Rev it up to 3000 RPMs and I still got the Code. I thought about it for a minute and went into the Garage and Pulled from my Stash 2 Knock sensors that I know came out of a turbo Engine. Install both the sensors and made sure I had a good connection on each...

I wish you guys would just post up everything that you know about these cars. I would sit here and read all day and learn through every Post. Well, Its been confirmed that it was in the incorrect Spot. I would have never Imagined that there would be a Extra Hole in the Turbo Motors. I have a Non...

I dont Crazy Question for you. If you look at the block from the Side that the Knock Sensors screw in. you Definitely know where the rear Knock Sensor hole is. and you see where the Front Knock Sensor hole is also. Question is what is that other Hole a little farther Forward but a Little...

I just have a New Harness. I have Multiple Knock Sensors here here that Basically Im installing, Running the car and Pulling out once I get the Code 52. I was told that the Best way to ensure Knock Sensors were good is to tap on them the way you recommended not too... Im going to redo the...

Ah, Got ya

Thats a Posibility. Wastegates are funny like that sometimes, Either Sticking Shut or not closing correctly. I would check it. Stock turbo boost is only 5-7 psi and 7 is a little on the High Side. All of mine boosted at or around 6 PSI.

That is correct. Everything right now is geared around the Code 52. Again, I can reset the ECU and check for any Codes I get Blinking light as no codes are found. If I rev the motor up to 2400rpms and check to see if anything comes on or if I have any codes.... Nothing but as soon as It hits...

Could be a sticking wastegate also. Code 34.... Abnormal turbo Pressure, I did this once to my car also and as soon as I shimmed it, Code 34 Popped on. Im sure you Know this but make sure you reset your ECU to get rid of stored codes. I forgot to do that before also.

Code 34.... If you have Wastegate Shims, Remove them and that will clear that up. Code 31... Wipe off your AFM Sensor with a """DRY""" rag and make sure your Housing Screw hasnt been tampered with. If that doesnt sove the Problem, look at the connections and ensure its plugged in all the way...

Im sure that would have nothing what so ever to do with the code Popping up would it. Im just throwing stuff out there. Its only at 2800+rpms that it pops on. I can rev it up t0 2400rpms all day and not get the code.

I will recheck the Sensors tomorrow and Give ya a Update. I really really want this Solved. Its just funny that when the Idle drops to the point that the car is Sputtering really bad and I lightly tap the top of the AFM Sensor the Idle jumps back up or slowly moves back up to normal Idle and...

Thanks I appreciate the Help on this matter. Im just at a loss here and Ive never ran into a Situation with a motor that I havent been able to figure out. Robert

I did, He said do a Re-Wire on the Knock Sensors but this was before I got the New Harness. So Im still Stumped at this. I need this car gone and for $4,000 Dollar Its my Motivation to get it fixed. Just need someone Elses thinking cap on this with me. Also, If I dont tap on the AFM, It...

Im having a Problem with a Code 52, It only comes on when I either rev the engine above 2800 rpms or I Accelorate it to that Level at Normal Driving. Ive Replaced both Sensors even though Both of them checked out fine VIA TSRM New 87-88 Supra Manual tranny Wiring Harness Straight from...

I think that is the reason I didnt buy it. I was looking at a MAFT that had theconnector cut off it and the guy had no Idea where or why he cut it off. I told him that you indeed need that connector to Simplify things and ensure things were connected Properly. Hope you get it all figured out...

Does anyone Know the Part number for a Temp Sensor so It can be reserached. Its for a 88 Turbo Robert
