Hey David, sorry about the low numbers. My AFR was also low-mid 10's. Chris wanted to keep it safer, so I don't think your problem is fuel. It could be better, but your not loosing 200RWHP from it. Are you using a different head/piston combo, and have resulted in a very low compression? 12...

Yes they are the same. the SC300, 400, and supra use the same auto trans. they have different versions, so the gears ratios may be different, but basically they are the same trans

I've only had a leak in the rear cam seal. I did have a valve cover gasket leak, but it was due to not getting it seated correctly when installing it.

Basically they are the same. there is no difference in torque capasity. The early SC's use a cable to adjust the fluid pressure, and the supra's do not. but the supra guys claim trans failure at 350hp. Mine was living at 320 hp, and lasted a week at the 370hp mark. (All rear wheel) The clutch...

black smoke is usally fuel. Blueish smoke is usally oil, and it hangs around longer. White smoke is usally water, and disapates quickly.

I don't mind at all. I'm not on this site very often though. I'm making 510 at the rear wheels, and have not had a problem with the trans failing. When the trans was stock, it failed all at once though. no sign of slipping, and it went with 370RW about 2 weeks after the turbo install...

I'm pretty sure chris has it. I think he posted it in a thread. I'll look for it, and try to repost.

Chris, If Ross had relieved the piston, the bad injector would have caused a lean condition, and probably blown out the head gasket (which all happen) but do you think the piston would have survived, and be able to be reused rather then us needing to reorder a new piston? Listen to this guy! Get...

Hey Jibby. Chris and I have done alot of work the the stock trans. I don't think you will reaonable be able to get the stock trans in the SC to run 0-60 in 4.3 seconds. I do think with some work you can get it to run a 12.7 in the 1/4 I have an autometer D-pic, and when my car was running it's...

I agree. Chris & I thought about relieving it originally, but Ross had those things balanced to some crazy tolerance of one another. I wish they had balanced them with the edges removed. This did only happen on one piston, so an injector may have been flowing less then the others. Wish is...

The Supra, and the SC are the same car. it's like a Camaro, and a Firebird. If anythin the SC actually has a slightly longer nose due to the styling. the Supra nose is a little shorter. But both car can fit an I6 in length, and both cars can fit a V8 in width. The SC400 isn't any different...

I think the quality of the piston is just as good as any. I wish ross would have followed davids piston, mold a little better, and removed this material, as in the stock toyota piston.

I think david hit it on the head. I don't think your going to get enough interest to get the headers mass produces in china, or anywhere else. I think your going to be making them by hand and producing 2 a month. (If that) when the GB went out for the pistons there was only a hand full of...
