Im not going to use a blockguard I've read too many horror stories of it sinking and overheating I think if I can get it tuned properly it should be fine Im probably gonna end up sleeving it next year with some Darton sleeves

as for the injectors I think they should be good up to 350-400 HP

I don't wanna lose my A/C so Im gonna keep my 2.5 DP
