how can the rb26 be a race bred engine .when if you want 600 + h.p the japs pull the guts out of them and do a full bottom end rebuild .yet they dont even look at a 1j under 750 H.p i think this quote from powerhouse says it all "In typical Toyota fashion, the Supra 3.0 liter in-line six is capable of withstanding large power increases without any aftermarket internal engine upgrades. One up-and-coming California tuner put it this way: "You open a Honda, you find a lightweight jewel of an engine where the components' strength is calculated to the last decimal place. The block's aluminum. Maybe you find an 11 mm stud some-where. You look in a Nissan, the corresponding stud's typically a little bigger-say 12 mm. But check out a Toyota: You'll probably find a 16. In a cast iron block, of course." You'd think these guys at Toyota were building earth-moving equipment, when it comes to creating strong engines. Manual transmissions break before Toyota engines, even at extreme power levels. HELL NISMO in Melbourne even told me they reckon a 1ggte bottom end is tougher than an Rb26 and the 1js are even tougher and the 2js bulletproof The 1j makes MORE torque ,more power is smoother and has a far flatter consistent torque curve .This is comparing the two engines with say 3 inch exhaust dump pipes and an intercooler (these are basically standard street mods) a 1j head on a flow bench flows better than a stock rb26 . The only reason GTR's are king of the Drag strips in Japan is they are a better car when it comes to traction .And probably better on the track .But his does not reflect the capabilities of the two engines .They are almost identical yet the 1j bottom is TWICE as tough now back to 2j vs RB26 this is a quote from autospeed 's Julian edgar (who owns a GTR) "With a gentle launch and two people aboard, we clocked a 100 km/h time of 5.5 seconds - and well believe the data showing others getting that down into the high fours. Yes, the GT-R has run quicker times than that, but as the owner and driver (for over 50,000km) of an R32 GT-R, I know that the Supra's flexibility and punch at all rpm simply walks all over the revered Nissan." ANd he owns an rb 26 ....It takes a big man to admit its better than own car and again "The 2JZ engine is the latest in ultra high performance engineering from Japan and shows a technological upgrade over the RB26DETT that propels Nissan's Skyline GT-Rs. There are strong similarities between the pair - both are straight sixes with a DOHC 24-valve head, two turbos, intercooling and of course EFI. However, Toyota's 2JZ-GTE has aced the RB26 by including VVT-i (variable valve timing) and a sophisticated sequential turbo system which improves the overall spread of boost (and therefore torque). The swept volume of the engine has also been pushed to 3 litres" HELL the experts CAN'T be wrong [Updated on: Wed, 20 November 2002 08:50] [Report message to a moderator]
