I had a por man type r in my da and went 13.2's twice. ON azinas. It ran good and vtec hit harder than any other car I have ever felt. It blew up because i sold the car to a kid and he wanted to test what i said about it not having a rev limiter, well he never found it. The gsr block is a very strong block and can handle some revs. the b16 head is ok but you wont keep it together if you rev past 9. the type r head has much better valve train and can hand;e higher rpms.
