Set up is 85x89mm 12.5:1 b20v
Itr head with full sk2 valvetrain and Pro2s.
Revving to 9k.
Current numbers are 238hp 172tq on a Dynojet.
Current manifold is a slightly ported 1st gen Edelbrock before they called it the victor x.

Which would be more beneficial? Some guys on the sfwd community page on facebook were suggesting a 4piston ultra street, any feedback?

Based off what I have seen you will lose top end compared to the edelbrock manifold. You need that plenum volume. NOW if you wanna get an ultra street and some spacers you are barking up the right tree IMO. Look up the test that was done and hit up Furyof4 for more info. Again this is my .02 based off what I have seen...

I'd need way too many spacers to justify switching to the street. Bump for more results maybe?

I'm looking for a dynojet , I'm sure it's going to read 252 ,
I think it did OK on my engine for a 84x89 , but just leave Victor X then and go 86x98 for more power

sucks that the firewall clearance is already close on the ef/da chasis.
