I read the posts of irev210 and bambam about the JDM B20 engines. The information is a little different to me, to make sure i recieve the right engine with 9.6:1 compression will it have a p75 or a p8r head and which intake long giraffe or the PHK with a grey plastic chamber on top. Bambam wrote the P8R head is 9.2:1. thanks for all your guys help

 

please learn how to use the search feature on this form.

 

Theres no proof of either..

My B20B was the 9.2 with P8R head. There are others at 8.8 wth P8R head. I have yet to see a P8R longblock at 9.6. The 2 layer HG theory maybe be on a P8R, but the P8R HG's if purchased are all 3 layer.

The 9.6 is the B20Z that has a knock sensor.

Manifold designs are all over the place with B20's from Japan since they are used in so many cars.

 

thanks EsotericImage for the help thats why i see differences in the posts.
