I'd go with the GSR ECU and put a knock sensor in there if you can. 9500RPMs is very high for a stock block LS/VTEC engine.LsVtecR said:i've got the ls/vtec swap done in my car. i still have the same computer because i didn't want to rev to high because the ls block won't be able to handle high revs. of course i didn't put new pistons in my car so i don't know how much of a difference that might be. i put on a blockguard too because i was told it would help my ls block out.
i'm just saying that 9500 sounds a little to high for me. i'd be scared as fuck to go that high.
