Hi all,

Thats my problem.

I put a turbo kit on my type R with rocket motorsport cams/springs/retainers

I rebuilded the base, (sleeves + news pistons/rings)

Everything is good when the Vtec is off (roading).

I changed oil after roading and before going on dyno, I found metal on magnetic oil pan nut (more than usual).

When I were on the dyno and put Vtec on, the power band of WHP/WTQ V.S. RPM engine dropped.

At 7000 rpm / Vtec off / 5 PSI, I did 202 whp, when I put the Vtec on, I dropped to 165 whp.

I heard the Vtec very well but whp dropped.

Can you help me ?


Thanks all !

 

either swap in some GSR cams or free up the exhaust restriction in the turbo setup. You either have a restrictive log manifold and/or small exhaust. A smaller cam will be a quick fix for you

 

I had a similar issue and it was because my rocker assembly was installed incorrectly

 

i would think the cams are too big for your setup

what is your turbo setup, and what cams did you put in?

 

had the same problem, switch to smaller cams - b16 for example

 

what would be the reason behind the excess metal shaving in his oil pan?

 

What turbo? What pistons / bore? What size exhaust / dp?
