hi,
my wira just change engine gsr 4g93 turbo.
the engine is vibrating & shaking badly at idle. idling 900rpm steady. above idling no vibrate.
mounting looks good.
also the spark plug should i use heat range 6 or 7 ?
as i know , throttle body dirty might cause rpm to dance up and down
but my rpm is steady, just the whole engine vibrating badly
on the road, the power is normal for a stock gsr
does anybody know any pistons from any engine which has bore around 78-79 mm n stroke around 83-84 mm and can withstand a compression ratio of 11:1?
I know, some might say this might be a 'long shot' search n I'm better off with a custom pistons. However, im trying to reduce cost in rebuilding my engine. Sharing of any info regarding above is greatly appreciated..
thanks in advance..
