Sorry for not answering sooner been really busy lately. My supra has a cometic metal head gasket an ARP studs toqued to 80 FT-pound thats all for the engine internals. The IC tubing and intercooler is stock the BOV is the cheapest that HKS makes. The turbo is a Garret t04 P trim 60-1 with machined CT26 compressor and turbine housings to fit the larger wheels done by Mike Turbo in Florida, stock log exhaust manifold, manual boost controller, HKS fuel cut defencer and the most important AEM digital UEGO Wideband O2 sensor. Recently added the walbro 255 fuel pump and an Aeromotive FPR. The fuel pressure is set to 49 on idle and I raised the boost to 19 PSI and feels much better probably getting close to the 400 RWHP mark. My next uprgrades will be bigger IC and pipes, HKS SSQV BOV, bigger injectors maybe 650cc or 720cc, and Lexus AFM. I have all of them ready to be installed exept the injectors.
