Piglet's Rebuild Of His Busted Tomei 2.8


Recommended Posts

Lovely Doublely.

You will need to tell me when she is getting a tune so I can come and have a look.

What is the run in proceedure going to be ?

I ran mine in a bit on the dyno then finished it off at the drags, LOL

Trailer to dyno, throw it on.... let Yavuz do his thing, go and put some kms on it (400-500) then give the f**ker HEAPS!

Better crack 450 on those little baby -5's.... The the big sucker goes on!

Here is something interesting

Here I was stressing about valve to piston clearence with the 1.5mm OS valves. Now with a 0.9 mm head gasket (smallest I could find), squish of 29 thou and cams with over 10.8 mm of lift the clearence on the intake was 2.2 mm and OVER 3 mm on the exhaust. I could have not relieved them :( So much for Tomei's "Over 10.8 mm relieve the pistons" GRRRRRRRRRRRR

Hey paul

Great to see the build coming together and yes that squish is all good long as its not below 28 thou . Wait and see the difference this will make.

Question what will be reving the motor too ? And what gearbox you going to have behind it?

Speak soon

Bobby, the box is a OS 1-3 gearset with the big dick input shaft. It was behind the engine before. It got pulled down and put back together since. Nice box but really needs a stroker to work.... Orrrr have smaller turbos!

I can't see myself revving any harder than 8000 RPM. I found myself with the -5's changing at 6500 and just ride the torque. See where the power drops off but 8000 RPM will be the shift point with the hard cut set at 8600-8800 JUST so I don't hit it.

What harmonic balance is that and what is that gear set running behind it? Its almost a shame dropping that donk back in the engine bay...just look at it? Its a thing of beauty

It's a Ross balancer and the "tooth wheel" is a trigger wheel so the timing isn't taken from the CAS anymore.

Oh you never know what's gonna happen with cams ;).
