Hey All,

New to this forum, but not new to Hondas. I have a JDM F20B in my 97 Accord Coupe. Problem is, I want to build it, but I can't seem to find the internal specs anywhere. Trying to find this info without taking it apart and measuring myself - I don't have a garage right now and its my DD.

Anyone know where to get a shop manual to answer all these questions? For shop/service/repair manual - the stock vehicle is a JDM 98-99 CF4 Accord SiR-T/Torneo. Otherwise, this is the info I'm looking for - any help is greatly appreciated.

Specs for all head internals. Rocker arms, springs, camshaft, valves, retainers.
Specs for block internals. Rods, crank.
Max tolerances for boring.

For those curious - stock bore/stroke is 85mm/88mm with 11.0 compression.
See link below for full engine specs.

What I'm hoping to do is find a way to bore and stroke without losing my high revving ability. haven't decided if final product will be turbo or NA, but that is really just a question for the pistons. displacement is your friend either way. LOL.

Any feedback on bore and stroke possibilities would be great too. Since it is an iron F-block - would I need to sleeve... or only if I go big boost?

Also... I see a lot of silly arguments about the power of an F20B out there.
