best head gasket ever

[Poodles]

sorry, didn't quite word that right, but the stock turbo will push that much with a turbo controller. Not saying the HG or the fuel cut won't kick in below that though

Basicly, turbo upgrade is only good in my opinion once you get your head gasket, fuel delivery, intake, and exhaust situation sorted, as the turbo isn't the weakest link. Once you get to the point where you need more than the stock turbo...go ahead and sink the money into an upgrade...

hello... I'm a new member but I know supras VERY well. Stock the supra runs 6.9 lbs of boost @ approximately 230hp . I'm not saying everyones car is the same, but that's how much toyota gave them. On my 88 supra turbo I bought the HKS metal head gasket from Suprasport. http://www.suprasport.com/product.as...id=96&catid=63 . I also figured that buying ARP head studs from suprasport would be a good investment considering how much the stock head bolts "twist". http://www.suprasport.com/product.as...id=91&catid=63
My ARP head studs are torqued down to 72lbs. I decided after 1000 miles after my head gasket job to see how well the head studs were holding up, every single one was still at 72lbs!

I have a shimmed wastegate, approximately 4 millimeters of shim, which brought me right around 13lbs of boost, along with a k&n intake and exhaust. For every 1mm of shim you can expect approximately 11-14 hp depending on supporting mods. My Supra has never been on a dyno, but I know it has somewhere around 300 hp and we are no where near finnished! Next mods to come are a manual transmission and a hard pipe kit for the InterCooler which will drop the turbo about 3lbs on the stock IC. Anyhow I wish you all the best of luck! See you on the streets!
