This S14 has been running with Garrett 2871-R turbo, the engine has piston and camshaft as well.
However this turbo, the boost is dropping with rpm increase.
Solution?!!try some other turbo?
So we got this TOMEI ARMS M7960 turbo from Tomei Japan as a testimony?
See What is the differences?
As you know this turbo comes with all you need, turbo, gasket, water and oil hose, piping etc.
And we tested with same car, same engine same dyno, just change turbo and compare.
Tomei turbo is slightly lager, however this is not ball bearing turbo.
And this is the result!
As we expected that response is slower than Garrett. Around 40hp at wheel more at peak, at almost same rpm.
Boost response is slower, however steady till top.
We have another option!!
