Stroker Rebuild Questions

[Kash]

Currently rebuilding my 280zxt engine with a stroker crank. I'll be keeping my stock L28 rod and dish piston combination (read somewhere that a smaller crank to rod ratio is better for turbos). The problem is, this set-up leaves me with a 2mm positive deck height (piston above block deck by 2mm). Can I run this set-up with a 2.5mm head gasket without any issues or will I need a 2mm fly cut to keep the pistion at or below deck?

 

Last question, how do I know if I need to get the crank polished prior to install or should this alwasy be done when rebuilding? All crank surfaces look excellent except for one main surface that has a light circular like stain about 5mm in diameter that is not detectable to the touch. THANK!

I think you need to do some research on the subject. Have you?

There is a massive amount of info here that is simply a few keystrokes away. Search, read, absorb and apply. If you're still not sure you can ask a question but we're more inclined to take you and your question more seriously if its obvious that you've made an effort to help yourself first.

Cheers.

Trust me, I have been searching...

Simple answer is Yes you can run a positive deck height. A guy by the name of Bob Hanvey did a great right up a few years ago about strokers, I am fairly sure it is on Hybridz but if you can't find it here do a google search you should be able to find it. Oh yea it is several pages long and some very good reading.
