as for the flywheel/clutch kits; we send them completely plug and play for about $550. it can be hard to come up with cores at times so very subject to availability.
I have just made a similar setup for my son, but we are having problems with the crank case breathing. The catch tank is filling up pretty fast when pushing hard on the track. Normal hard driving it works fine. How is this project handle the crank case breathing?Its got stock pistons and not much boost so its not a problem. you will likely need to add an extra breather port on the valve cover and make sure all breathers are vented to atmosphere and no boost pressure is being fed into crankcase.This is our project (in Norwegian, but the pics tels a lot).http://bimmers.no/forum/viewtopic.php?f=11&t=223632&hilit=robins
