Hi guys,

I'm building a Honda Civic RTSi as my daily bitch.

The car is a Civic EG real time 4wd sedan with a D16z5 engine in it.
It's the same engine wich was installed in the CRX ED9 here in europe.

It's a D16 DOHC with 124hp.
I think it's similar to the D16A9 here in the USA.



Now my questions.

I bought a D16 JRSC wich i will run with around 6psi I think.

I also bought some NipponRacing D16zc pistons and SCAT rods.
I'm not sure what CR i will reach with a 0.030in COMETIC head gasket and if I can run it with the JRSC.

Please let met know something about it.


Thanks

 

here is a calc that will help

just remmber what JRSC like

Optimum: 10.5:1

Suitable: 9.5 - 11:1

Compression ratios from 9.5 - 11 : 1 are suitable for a blown application (depending on fuel and tuning).
Lower compression will allow higher boost levels, but the JRSC is boost limited to under 1 bar (14.7psi).
As such build the motor as high as can be safely tuned. In my opinion this is ~10.5:1.

"quoted from FLTracing.com "

 

the calculator says around 10.5CR.

I think with a sligthly deck and block milling arround 10.5-11.0CR.

could this be true?

 

looks like your on the money

 

sounds good

thanks a lot
