I put this guide together because I'm tired of seeing the SAME threads over and over of simple questions that can be answered in one simple post like this one. This thread is designed to be an end-all, tell-all type thread. Please keep in mind though, that this is still just a general guide. Lsvtec/b20vtec engines are not honda manufactured engines. With that said, there are hundreds of combinations you can build.
Also, please be aware that this guide is assembled on an intermediate level, and anyone reading this guide can perform all of the steps outlined.
Let's begin. Now, there are a few NECESSARY things to do/parts to buy when building a "reliable" lsvtec/b20vtec:
-LS/B20 (same) ARP rod bolts
-GSR/ITR (same) ARP head studs (NON-B17)
-
New LS (90-01) B18a/b (for 81mm) or B20 (for 84mm) head gasket (MLS) or aftermarket for your non-OEM bore
-New ACL bearings - LS/B20 (same)
-New Hastings piston rings (or OEM)
-New OEM D/Bseries (same) valve seals
-New OEM Dohc Vtec Bseries (B16/GSR/ITR) 22T water pump
-New OEM P72 GSR/ITR timing belt (not B17)
-New OEM P72 oil pump (96+ GSR/LS/B20/ITR/B16 - all the same)
-Magnetic oil drain plug (important for break in)
-New NGK V-power BKR6E spark plugs (stock LS pistons) OR NGK V-power BKR7E spark plugs for 10.0-12.0:1 compression, or NGK V-power R5671A-8 plugs for 12.0:1+ compression
-Adjustable Fuel Pressure regulator (necessary for stock ECU/injectors)
-In addition, you should replace all remaining gaskets and filters
Note- "same" means that the listed parts use the same part #'s from HONDA/ACURA.
