i still believe 150 is achievable with that before turboing it. lookin through threads on my mates honda tech account there was a guy put out 150 with skunk2 mani exhaust and filter and thats basically what he is aiming for. original plan was to get cams inlet mani and valve springs but the cam was discontinued. sure it was skunk2 one he was going for. dunno if he was gonna raise the limit or not. guess he will see how it runs. so now the plan is to make it to the spec i said and get it in the car running properly the way he wants and then get it off the road again to turbo it. as for expenses im not fused because its his and i just help with everythin so dont cost me. to be honest i think he doin this in spite of folk who say just get a b16 or 18 lol. just like on here when someone asks how much power can be had with a 4efe most responses say get a 4efte
