HybridHydra Posted January 21, 2015 Share Posted January 21, 2015 I have a stock drivetrain. For transmission I'm thinking a OS-Giken Super Single Clutch. Is there a difference between the NS081-AB8 and the NS081-AA8? For the engine, I want to bore the engine out to 3.0 or 3.1 L. But I don't know if the N42 block will be able to withstand the HP. Me questions is- Are the upgrades I want to do, to my N42 Block/Head which is only at 90K miles, going to be ok? Quote Link to comment Share on other sites More sharing options...
NewZed Posted January 21, 2015 Share Posted January 21, 2015 The clutch won't add any power. You'll need a different/modified crankshaft to get to 3.0 liters or more. Browse here - http://www.rebelloracing.com/enginebuild.htm After adding parts, the 90,000 current miles will be irrelevant. What happened to the RB26 swap?

HybridHydra Posted January 21, 2015 Author Share Posted January 21, 2015 RB26 is a swap I can only dream of. If I wanted to buy a new engine I would do the RB swap, but I currently just want to modify the existing engine. Quote Link to comment Share on other sites More sharing options...
johnc Posted January 22, 2015 Share Posted January 22, 2015 You're all over the map with your questions. Please take some time and do some reading here. There are over 10 years of discussions about 3.2 and 3.1L engine builds. All your N42 questions have been answered. You just have to search a bit and find them. Regarding the clutches, go to the OSG USA web site and read up, or call them. Quote Link to comment Share on other sites More sharing options...
