Here is a link to a guy that has done this convershion as i was going to do the same but as a street car i found a problem
with the SR20det and de unless you get the head off a gtir thay don't handle alot of power as thay have rockers and thay
can brake not offen but it will distroy the motor if thay do si i have desided to go with a CA18det as thay don't have the
problim and you can nealy have a full rebild for the price of a SR20 half cut
