Is it possible for a modified 7M to go lean at WOT with 660cc injectors and Lexus AFM? Assuming the largest plate intercooler that will fit in the car, hard pipes, 3 " exhaust without cat, professionally ported head, ported exhaust manifold, and rebuilt stock turbo at 18 psi or so, fuel pressure...

My oil pump shaft is badly scored but the rest of the pump, specs/looks fine. In midst of major rebuild after spun bearing. Any point in trying to replace just the bushing ($45) and polish the pump shaft, or is it better just to replace the oil pump ($255)? THough money is tight, peace of mind...

I'm looking all over for replacements for the rear brake dust shields on my 89 supra. New ones are over $600 for the pair, not worth it. I finally found a solution that anyone can easily use. I picked up two air cleaner holders from older chevy pickups - the smaller ones, not the full size...

I spent the day researching new turbos, and ended up writing Aaron. I would like to get community response too, if possible. My goal is a responsive and powerful engine for driving below 90 mph, for daily driving. If I ever get time to go racing it would be drift racing. The first version...

This is for everyone's amusement at my stupidity, so don't waste your time reading further unless you have a sense of humor. My oil is disappearing, about as much oil per gallon of gas as a chainsaw uses, but it's not coming out the tail pipe, just take that as a given. It's not dripping...

I'm really amazed by the worksmanship by some of the people on this site, so I want to be clear I'm doing amateur work with poor tools. That said, I modified my stock exhaust manifold, as others have done, and perhaps went slightly farther than most. I had worries about structural integrity...

I have narrowed down a problem and not sure what would be most productive to do next. I had multiple problems originally, so I'm starting this thread now that some easy ones were weeded out. Problem: Car starts great, runs a variable amount of time - seconds to 1/2 hr. then suddenly...

I'm ready to start work on my MKIII suspension, and I would love help figuring out what to blow a little money one. I would like to spend less than $1000 in parts, not including the dampers. Background: I have an NA-T swap, mid to late '89 body, TEMS apparatus added from a parts car. This is...

I wonder if I have a problem due to "upgraded" spark plug wires and would appreciate some advice. here's the story: I have a few simple performance mods, new low resistance MSD wires. New copper plugs were selected and gaped per writeup on this site (but I can't find the specs at the...

I'm putting a rebuilt JDM 7m-gte, probably 1990 or later, into a 1989 supra with manual trans and 7m-ge engine. Got the car all built and then the last step: harness doesn't make it to the glove box location of the ECU. Is this because it was from a LHD car? I have an extra harness from...
