beefing up an H22A...

[96civic_buildup]

Like everyone already knows i'll be putting this in my civic hatch and i know everyone is probably tired of hearing about it, sorry i've just got about a million different questions. These questions are concerning an N/A H22A setup. What would be the highest compression i could run on 93 octane gas, or is there somewhere i could calculate this myself? Also are H22A internals (crank and rods) pretty decent? Also how well does the H22A head flow, basically wondering if i would notice a difference if i forked out the extra cash and went ahead and had it ported and polished? Last question if there is anyone who has any tips on building a H22A or honda engines those would be great too. Like are there any really specialized tools i'll be needing? (right now, i have all the tools necessary to build any kind of ford or chevy motor) Or are there any little certain things you would do while you had the motor apart, not meaning replacing rods and stuff, but more towards the little stuff. Thanks for the help once again.

i have this swap in a 90 accord and it runs real good but im trying to save and do the same thing u are doing. for compression my opinion would be to run Type pistons which puts you around 11:1 which is a safe as it gets. the internals are good but there not the strongest in the world. i heard of people swaping out the crank and rods for the f22s. also the h22 dont drop right in you would have to buy a mount kit. and your also going to be spending some bread on your suspension if you want to hook. my car is probly 400 lbs heavier and have hell getting to hook when im on stocks. one big difference i notice on mine is that stock pipe and my exhaust system makes the biggest difference than any other mod on the car. while you have the engine out and before you put it in. my opinion is to change timming belt, water pump, plugs n wires, and put in after market flywheel and clutch. i run with a 6 puck i got off ebay and fidanzza flywheel. sorry for the long response and as for tools the main thing you will need is 10, 12, 14, 17, 19, and 36

well the compression would depend on tuning, but theyre people running 12-ish compression on 93. i havent seen much internals for sale for the h22 but lots of people run them stock, atleast for all motor, and theyve held up pretty well. but if theres going to be a major increase in torque/hp, then i recommend upgrading the rods. port and polish is more noticeable in the upper rpms, usually.

if i were you i wouldnt rebuild my own block. have a professional do it.

Sorry i forgot to mention i'm an automotive major so my professor will be looking over me every step of the way.

ok so perfect you can rebuild it. you should konw the equipment needed since it is yoru major

[96civic_buildup]

it's not that i didn't know what equipment would be needed to rebuild it, i just know that some engines require special pullers or special tools. This i the first time i will be tearing into a honda engine, so i was just wondering if there were any special tools needed if any. I didn't mean to sound cocky. If i knew everything i wouldn't be on here asking more knowledgable sources for information. Sorry i just didn't really know how to take that last little statement, it might not have been meant to be intrepreted that way but i wasn't sure. So basically i'm still learning, and the only way to become more knowledgable about these things is by asking questions and experience. Thanks for the replies though.

yes there are alot of speciatly tools that are required when re-building a honda block. the one that i ran into when i rebuilt my b16a was the need of several different types of valve spring remover tools, all i got to tell ya is it took me almost 2 weeks to replace all of them, and i know what im doing. but your better off getting a helms manual (www.helminc.com) and looking in that, becuase it lists all the special tools required for each major step in the motor breakdown.

crxlvr, thanks that site was very helpful, i'm definitely going to order one of thier service/shop manuals. Just curious where did you get or find the specialty tools for the valve spring removal? thanks.

Also i forgot to ask, i've come to understand that the H22A has FRM (fiber reinforced metal) cylinder walls, correct me if i'm wrong. I read somewhere that because of a such a thin cylinder wall boring or honing weren't a good idea? first of all, is this true, and second how would you be able to get rid of a ring ridge in the cylinder wall. And last i've also heard these motors don't like boost for this very reason (FRM cylinder walls and obviously the high compression, lets just assume i lowered the comp to 9.5:1, and a good tune) does this still stand true? (basically will the FRM walls take it?) Sorry one more question with the H22A going into a 96 hatch would 13's be a reasonable goal with an N/A app with mods? (also i realize the question will be what mods? this is kind of what i'm wondering, so input will be great.) thanks.
