hi would luv to build a turbo engine for lego but am not sure what i need. ive got a spare 998 at the engine shop now getting acid dipped and crack tested and have a set of 60 thou standard pistons will these be ok to use in a turbo motor. and r the bearings special as well?
cheers matt
im using hypatec 60+ pistons in mine so far with 6psi boost and no troubles, bearings are just your normal bearings. the only thing that is really different is the compression and cam (dont want a massive cam).
anyway a bit of an update hadnt done much this week as i was waiting for my carbide burrs to arrive so i could grind the inside of the pipe as i went along. They finally came today so managed to get a little more done.
also had a little play with my tig tday and managed to weld some alluminium without it melting into a ball
oh and about a kit maybe one day but deffinatly not for a while , wait till this is all sorted and no bugs in it. wouldnt want any problems. Also they would be alot of parts to change or source for it as the manifold is just one of many items needed, you would need a sutable high pressure pump + regulator ,new exhaust , Metro turbo carbie + manifold + plenium and the turbo air filters things like that.
