one of our guys has a crank from an engine that the HG blew on so hes gonna pull it out and have a look at the condition of it. Will keep ya posted.
i had a tubular top mount manifold, and again frees up breathing at higher boost (1bar+) but if not used with a cam as well it may be a bit disappointing. The tubulars make the turbo come on boost about 250+rpm later, so without the ability to exploit the benefits of the extra breathing of the tubular manifold (bigger turbo, better cam and inlet manifold imho), the worth of the manifold is compromised. Does make turbo access much better though!

Fair enough on the cam mate, and had some interest on the crank on sxoc! win! how much for the forward facing manifold? your right the standard inlet plenums are poo and make for hideous piping angles! it looks like the guy who wants the crank doesnt want the bearings, so maybe another for sale thread in a mo!! best to get bearings to suit the crank rather then grind the crank to suit the bearings! you mentioned a rebuild, dont need any race bearings?ha ha! is the cam Gripo has for sale similar profile to yours? only ask as i dont want an all or nothing engine, would rather have smooth delivery as you said have driven cammed turbos before and you spend half your time waiting then the other half holding on for your life! dont get me wrong i like a bit of a kick in the back but i want the car to be useable other then when im giving it beans!!

thread showing the manifold for sale
http://www.nissansilvia.co.uk/vbb/sh...?t=4757&page=4 Gripos cam sale thread http://www.nissansilvia.co.uk/vbb/showthread.php?t=4730 sorry, your bearings wont help me with this rebuild. from memory the stock cam is something like 248deg, 8.8 lift and the Piper is 268 and 10.5mm or similar. the std cams so soft that almost as soon as the engine starts to make good power from the turbo, the cam starts to restrict with little lift and low duration. Your call, but personally without a decent cam the numbers might be there but the power wont be able to be exploited imho. I run the Autosprint cam currently, in fact mine was the first one that Geoff created using my engine spec as the basis. In real terms the Piper or Autosprint will give the improved performance in the range of boosted rpm.

Guess this is still available, what cc are the injectors mate? i currently have 440cc not sure on the maximum hp they will handle with a 255 pump, just checking if the injectors are needed also. is the price delivered?

injectors are 444cc. So long as your pumps up to it and you have an adjustable fuel pressure reg, they should see 300-320hp.
