300rwhp with the stock automatic transmission is somewhere between 350 -380hp at the flywheel. While you can reach that goal NA it will not happen in a "reasonable cost"... Depending on how talented you and your FRIENDS are... the least expensive way to get 300rwhp is nitrous, supercharging...

Absolutely. Rock-a-lex over at CL has a 2000 GS400, 4.0 with K&N Fipk intake, NEO fuel tuning and S&S headers reports a best dyno of 282rwhp 306rwtq. This through the stock automatic transmission. Converting to a 5 or 6 speed manual would likely get it very close to 300rwhp. Doing some...

Merry Christmas everyone! Blessings to all!

Steve, simply replace the center muffler with a piece of 2.5" tube. Cheap, simple, effective. You stated that the shop that installed your system didn't use your Y section you purchased. There is NO TELLING what they did and I have the suspicion that they used crush bent 2.0" pipes into a...

Steve, did you ever look at the pipes your shop installed? Have pictures? Not sure of the design of the Genie muffler but it may be like the standard glasspacks like Cherry Bomb's that have louvers punched into the flowpath creating huge restrictions. You NEED... Good merges, Y...

JBA has been building shorty style headers for a long time and (as far as I know) has a good reputation for quality. Keep in mind that while the headers will bolt to any of the xUZFE engines they are chassis specific... the 2UZ engine are truck engines and those headers do not fit the sedans...

VERY impressive video there! 8 second street car on full exhaust! Wow!

The tundra outlets are too far up and back and do not come close to the SC engine compartment. Dramatic reworking would be required.

It has been extensively discussed here on Lextreme and elsewhere. Search Tundra headers. Also, Chinese stainless products can have issues. See here. http://www.theturboforums.com/smf/newbie-tech-forum/why-not-to-use-cheap-304-stainless/

Remote/rear mount turbos must use smaller turbine housings or even turbines and housings since the gasses cool. Even in a front mount very close to the exhaust ports your relatively large turbo will have relatively slow boost response. Mounted as is in a rear/remote installation the boost...

Were the alt parts OEM? If not how much would the parts have cost through Sewell or other OEM source? Reason for asking is I find the OEM to be outstanding from oil and air filters on up... BUT... non OEM to be questionable and not worth/hardly worth the savings. I have the Arnott upper...

Notice anything unusual here??? http://www.compturbo.com/projects/theshop_viper

So... the alternator does not work? Mine is good with 185k miles and 12 years+ on it.

Only on models utilizing an off the shelf compressor and housing. Their site details changing the ratio of blade to center on compressor wheels and that increases air flow area for a given inlet diameter. They also use essentiallly axial turbine wheels giving a larger exhaust outlet and...

If these really do have acceptible reliability they will be outstanding for many uses especially low mount and remote mount where a pump is normally used. Does anyone have pricing?

Rob, welcome to Lextreme. Your SC is very nice, very clean. Your 90 cid supercharger is really not designed to make much over 300rwhp. At that level dual 2.25" pipes have the advantage of less weight, better ground and chassis clearance than the larger and heavier 2.50" pipe. Performance...

Nice! I had Norm Drazy, then owner of PSI, send one of their earlier units to C&G Marine in Miami FL back in 1992. We bolted it on to one of Randy Garciga's 572 BB Chevy offshore racing engines . I was WAY overconfident that it would make easy work of the roots blower it replaced...

Obviously your combo is making GREAT power. That said is the numbers shown on your dyno sheet comparable to say JustenGT8s ? Since Justen has/had the best results posted for a stock assembly until you posted this. Both of you have an excellent grasp of the variables so this discussion is...

Metal, welcome to Lextreme! Please post some pics of your car. Always liked the 240z. I bet it is lighter now with the 1uzfe than that cast iron 2.4 straight six it came with. 12.6 in the quarter is very respectable as NOT one of the "muscle cars" of the 60s and 70s ran in the 12s...

Thanks MBE !!!
