T-Rex vs Cheetah

[Ruko]

I am looking at getting into some power valve cyl's and of course T-Rex and Cheetah are the two contenders. I've seen a couple T-rex machines around but I've never seen a Cheetah. They both cost about the same but is there any advantages or disadvanteges to either??? I believe The Cheetah's are a nicosil bore compared to the cast sleeve in T-rex, but is there any other big differences??

There are many differences but you asked for big differences and pointed out a few of them already.Other big differences would be, it costs more $$$ in porting to bring the T-REX top end to match the power of the Cheetahs.The T-REX top end uses a billet "coolhead" type of head wich domes are interchangeable, while the Cheetah cylinders come with a cast "stock" type of head wich you will need to get machined or even changed if you want to change compression.The T-REX uses 4 transfer ports vs 6 for the Cheetahs and finally but most importantly, pretty much every shop can get the Cheetah cylinders to run well while very few can do a great job on a set of T-REX cylinders.

The Cheetahs are the way to go.I have seen T-rex and Cheetah top ends used and the Cheetahs are dominating.I'm not saying the T-rex is not worth it but The Cheetahs are capable of more.I can't wait to get mine.Of course any aftermarket cylinder will be an improvment over stock when going realy big.
