Does anyone know a shop that could perform the wrench report on the Tri-Z (head and cylinder) ?? I live in Michigan, and I'm willing to send the parts to someone who knows what they are doing.

Thanks

i did mine myself. raising the exhaust port roof was easy, however it was a little tricky adding the extra boost port in. you need to drill a pilot hole first, then open it up with a die grinder. the head can be milled at any automotive machine shop. plan on getting the cylinder bored and a new piston after the mods are done. the compression should be around 160-175psi. also put in new reeds if you haven't changed them recently. boysens carbon fiber reeds work good. instead of cutting the stock pipe, i bought a dg pipe and silencer. the main jet was increased two sizes to a 500. these mods make the z hit alot harder and later.
i also just recently bought an LRD pipe and silencer. haven't tried it yet and just found out that they stopped making them. good thing i bought it when i did.
