boosted98gst Posted January 3, 2010 Report Share Posted January 3, 2010 Hmmm thats weird, the issue I had with mine was it held good and felt decent, but would lock me out of gear in high rpm. Spec ended up sending me a new pressure plate and the new one did the same thing, then I just went with a twin disk and never had the issue. Once I go biggger turbo I will go back to a twin disk set up. Quote Link to comment Share on other sites More sharing options...

Flybye Posted January 3, 2010 Report Share Posted January 3, 2010 Get one of the Spec plus series clutches....They have a little stiffer pedal feel and can hold the power ALOT better. Quote Link to comment Share on other sites More sharing options...
Diamonds Posted January 3, 2010 Report Share Posted January 3, 2010 Get one of the Spec plus series clutches x2, they are worth the extra coin too! Quote Link to comment Share on other sites More sharing options...
Farkas Posted January 3, 2010 Report Share Posted January 3, 2010 (edited) well the engine was shifting at 9500 rpm they told me I would run into this issue with the weak tranny. An RB spinning to 9500? http://forums.nasioc.com/forums/images/smilies/blankface.gif I don't know about the tranny, but if the clutch was simply too soft, of course it's not going to withstand 9500 revs. I had an identicle problem with my AE86 when I was revving it out past 9- There wasn't enough clamping force of my pressure plate shifting between gears so it acted just like a slipping clutch. Speaking of Spec Plus series, IIRC I think that's what's going on my 20v... I bought 3+ Edited January 3, 2010 by Farkas Quote Link to comment Share on other sites More sharing options...

Speaking of Spec Plus series, IIRC I think that's what's going on my 20v... I bought 3+ No not my RB this was years ago, I was running a solid lifter/ solid cam fully build machined head,sleved, alum rod,sr20 I could of rev'ed higher then 9500 that was my peak power for the turbo. The head /rotating mass was good for 10k+. You can buy off shelf heads for 11k rpm for drag racing now in the states for decent prices. And yes you could easly build a Rb that rev's 9500, its very common for guys who run soilid lifter/cam/ and high vol oil pump and collar's to rev 10k, my car will not be able to this spring but maybe later I have a baby turbo.

boosted98gst Posted January 17, 2010 Report Share Posted January 17, 2010 Looks great! You going to delete that lame water cooled oil cooler? I figured you would of deleted all the plumbing for fluid routing since the car see's the track a lot. You would be surprized how hot that oilcooler raised the water temp. After deleting mine I seen a big improvment on my last engine. Quote Link to comment Share on other sites More sharing options...

BIGGU Posted February 28, 2010 Author Report Share Posted February 28, 2010 tax return came in and im ready to order parts. so ive been trying to figure this out for the last few days ive been trying to figure this out with no luck plan is a 1jz head on a 2jz bottom end. head will receive 272 BC cams, BC springs and retainers, Bc +1 MM valves, all the normal built head necessity, 1.6mm metal head gasket. question is will a +1 mm valve cause an issue with the oem 2jz pistons? motor stock is non interference and with the thick head gasket I think it should be fine but I cant find anything for sure. so i could just say fuck valves and screw the port and polish and use that money to get the turbo and other goodies OR i could just get it done and delay the motor more if i need new pistons and rods. oh also i have a r154 on its way some time to hold the extra power im going to put down.

boosted98gst Posted March 6, 2010 Report Share Posted March 6, 2010 so today i ordered my BC cams, BC springs, BC retainers, AEM cam gears and a few other random things. Just to ask a question why the head work when the car is on stock turbos? Wouldnt a turbo upgrade net much more power then head work? Or I could be wrong and the turbo is already done? usually 2.5 liter inline 6 engines/ with stock valve train and stock cams are good for over 500whp easy all day long.
