i have a 90 civic sedan with a d15b block with a d16z6 head on it... my motor got hydrolocked and now i wanna rebuild it for boost.... what pistons/rings/rods.bearings should i use to rebuild the motor.. also will it be worth rebuilding it?? does the z6 head on the d15 block have too high compression to boost?? also in rebuilding the head what cams valves retainers springs and everything should i use to be able to boost!! i am ttrying to do this to make my car a lil faster i dont want to go b series cause i already spent alot modding the single cam .. with clutch flywheel new tranny d16 head with headers and everything.. so i dont want to have to do it all again with bseries... so what can i do as apposed to intake manifold injectors fuel rail and everything in order to make the d15b/d16z6 head work for boost.... also how much horses will i be around after all this!!

Yeah you can rebuild the stock block. You can run the Vitara pistons with fjt rods for running boost in a D series, I believe you have to overbore the motor to 75.5

The stock motor wil be fine to boost if you just do a stock rebuild on the d15.

Go to the website, fjtdistributors.com they have ALOT of packages for built bottom ends and top ends.

You can use the stock intake manifold fuel rail and fuel pressure regulator. They all have proven 3-400+

thanks very helpful... but when i rebuild the fact that it has been hydrolocked will not effect the rebuild will it?

well obviously if there is any serious engine damage then a lot of your current stuff is going to be junk. If you take everything apart and everything is still within spec or you're able to get it within spec there shouldn't be a problem.

Sorry if you wanted a more detailed answer, that was the best I have.
