I have a JDM B18C i think its a GSR the top end is stamped p72. The head is built and i have a skunk 2 intake manifold with a type r ob2 computer and an lsd tranny. do i currently have more HP then a usdm type r ??????????

 

You can never have more HP than an aRRRRR

 

thanks for the help

 

Just have it dyno'd.

 

Why is this in the ITR forum? You're better off posting in the hybrid or all motor forum if you want any real answers.

 

Hmm dyno it and see. Saying it has a built bead tells us a lot.

 

What do you mean by built? What cams? If it's anything more than stock ITR cams by running the factory ITR ECU you probably aren't gaining anything. I've seen GSR dyno results where they installed skunk2 cams and made 2whp more (literally) than previously, which was still less than most stock ITR's, because there was no tuning.

 

i had my ITR motor throw a piston form a bad sleeve. I then put in a stock JDM B18C with a skunk 2 intake manifolod. I also had the head port polished and flowed. I still have my type r tranny and computer

 

As long as it's a healthy engine you are probably putting down comparable power to a stock ITR motor. As long as you had the head on a flow bench after the port and polish to verify that you didn't actually lose flow, which i have seen on honda heads alot. ITR heads are hand port and polished, and a skunk2 intake manifold is basically just a carbon copy of a stock ITR manifold. The only thing that might be holding you back from making the same power could be a lack of ITR cams, or comparable cams.

 

when I did the compression test it was making 225 accross the board and it was put on the flow bench after it was port and polished
