My s14 Kouki with a 3.2L RB

[wiring specialties]

Hey again everyone.

 

 

This is my personal project and my company demo car that we have been slowly building for some time. In the link is the 2010 setup when were were running a stroked RB30 to 3.1L. This past summer the block was sent out to a shop in Chicago where it has been stroked even further to 3.2L. We hope to have it back in the car early this coming year and get it out for some driving once again.

 

To our knowledge, there is only 1 other 3.2L RB in North America. It is an S13 out in Chicago that we wired up last year.

 

A few details:

 

3.2 L RB30

Twin HKS GTRS

740cc Nismo injectors

Aussie Rods and Wiseco Pistons

AEM

 

The head is an RB25 head for the RB26 manifolds. I really wanted to stick with cast iron reliability. I had a few manifolds crack on my SRs, till i went with a Fullrace custom unit. These came with the Turbo kit, so i am running stock manis and needed to re-drill the head. No problems and was done when the head was being worked on for the RB30 install.

 

Power comes on very linear and has been very reliable. On stock RB30 cams and a conservative tune I made the following:

Made 380WHP and 390 Tq at 9 lbs of boost

Made 545 WHP and 550 tq at 20 lbs on 94 octane

 

With aftermarket cams and a more aggressive tune for the track, should be able to make 600 whp at about 20-22 lbs psi.

Will post up more pics here as we get the new block back and get back to working on the car. If you have any questions about the build or just want to comment, don't hesitate to post up.

haha thanks

It was a bit of work but it was fun. Can`t wait to get the motor back from refresh.

 

This was from last year when the motor was still 3.1L
