Hey guys i'm looking for a set of forge pistons and were looking at this brand.
ACL. http://www.aclperformance.com.au/NissanSR20DETForgedPistons.htm
Then there was this remark that made me slightly concerned.
What does it really mean?
"(Note : Piston does not have oil squirter reliefs for GTiR motors) "
Can i still run this pistons or it's just that i won't take full advantage of our oil squirters?
Another brand i was thinking off is JE and CP pistons which are available in Malaysia. Are they reasonable pistons to consider?
But then again would i have the same issues like the above quote in regards to the ACL pistons?
Or end of the day it doesn't really matter or stick to stock pistons.
End of the day i just want reliability.
Another question is regarding piston to bore clearance.
I heard we need to run much more clearance compared to normal cast pistons.
If i recall roughly, 0.01 - 0.03mm for OEM cast pistons vs 0.0889mm or 0.0035inch as recommended by CP.
What i'm wondering if this would not be too good for the engine in the long run in terms of reliability? I'm no engine builder but there must be a reason for OEM specs to prefer cast and for HKS to build their pistons to allow lesser expansion so that they don't require to run more piston to bore clearance.
Btw i did read the high and low silicon content in forge piston article in the sticky. Good read.
Just leave more questions....
So what' s your opinion guys?
Need a quick decision b4 i take the plunge.
