Gsr Rs lag/no power and response issues.

[Wira3047]

Hi Sifus,

I am using a GSR RS and recently my conrod bearings gave away.

I have changed all rods and bearings,the foreman also polished the crankshaft as the bearing mounts were kinda giving away.

I had also installed exedy 3 puck clutch plate and adjustable cam pulleys(Not tuned yet).

I have a tial wastegate fitted with fuel regulator.

My car is not powerful at all as to no pick up and the response is slow.

I'm boosting at 0.5

It used to be powerful when i used a normal downpipe before however now there is no power at all.

There are no leaks as i have checked for any.

I need some advise as to where should i focus on fixing this issue.

Appreciate your help and inputs.

Thx,
Ruben

Bro not stock boost. ...m using 0.5 spring rate for the wastegate.

The issue is it lags terribly.

is the adjustable cam pulley set already? the timing correct?

how big is ur current downpipe compare to before? too big will cause u lag as well
