Well we've been tried many twin turbo set up, this time TOMEI M7655 twin turbo to try and check!
This turbo kit comes with all parts you need, and just under US$3000(NZ$3500).Good cost performance !! How about real performance???
We tried with this R32GTR 2.6 liter, camshaft, piston etc.
The power(purple line) is compared with Garrett 2860-5(red line), the top end power is almost the same, and boost response is..
Garrett turbo is almost 500rpm faster responce, Is this ball bearing advantage?, It could be.
We have another option!!
