Well since there is no nitrous section so this is close to it. I am putting a H22a in my 93 cx and I want to get 12's without spening gobs of money and I never owned a H series and I heard they have weak bottom ends. I was wondering if anyone can help me hit a 12.999999, the motor is a h22a with a dc header and a skunk2 intake manifold. I was wondering how much nitrous will the h22 hold, someone told they will hold 125 shot but I only want a 75 shot with a fuel pump and regulator. So can anyone help? Mods move this if in the wrong section.

 

they go as good as gravy to potatoes

 

thanks but I some definite answers so I don't blown my motor. thanks

 

the blocks, actually, are very strong, its the pistons and rods that are weak. Since the "big bucks" come in to play when sleeving a motor, you wont have to do this. a set of the FRM compatable pistons and some eagle rods for less than 1000 and you'll definately have a 100% daily driver that'll be able to take a 75 like no other (just make sure its tuned, as always).

 

but what about stock with a tune

 

like peas and carrots

 

I've never owned an H-series, but I have read and seen many guys push 75-100 through a bolt-on H22.

 

what do you think I would run a 75 shot and slicks. I don't want to expletive this motor because I heard I can't hone the sleaves if I expletive the rings up.

 

compression and leakdown test that biznatch ,tune and spray away

 

Basically stock H22 in a Civic with a wet 75 shot will get you 12 second capability. I'd suggest slicks, but if you want to keep it full-street 225 50 15 BFG drag radials will do ok. We've tried many different set ups with Hs in Civics + nitrous. You'll love it...

 

What about changing the pistons. Do you have to lower the compression or do they have to be forged or can I run on stock pistons. I was wondering because I know that the h22 doesnt like forged pistons.

 

It all depends on how much nitrous you want to put through. It's usually best to stay around a 75 shot or so with stock internals. If you want to fully build the motor you can run over a 200 shot, easy. Usually mild compression is pretty good with nitrous (as long as you're tuned of course). When I say mild I mean 11:1 to around 12:1, give or take a bit of course.

H22s like forged pistons if you sleeve the block

 

Yeah, but I'm looking for a way so you don't have to re-sleeve the block. Do you know of any other pistons other than Mahle that are compatible with a FRM block? What about just getting new OEM pistons? I will be changing the camshafts, rods, retainers, valves, ring lands, but to re-sleeve it is another expensense that maybe I could avoid with some good pistons that would not damage the h22 sleeve. What about running 100 shot? Is that too much for what I'm looking to do?

 

highjacker jk, would I have to upgrade my fuel to handle 75 on STOCK motor

 

I had an h22 in a del sol spraying a 75 wet shot. I f**king loved it, stock motor ( except for fuel pump, cams. throtle body, pullys, header and exhaust. It was an easy 12 sec. car. I would highly recomend it.

 

So a 75 would be fine, what about dry shot I like wet but some honda people said dry is better 75 and below?

 

a local tuner here has an h22 (stock block) spraying a 100 wet shot.

car moves like no tommorow. he's been running his setup for a while without problems.

as for what is better (dry/wet/DP) there are alot of threads covering that.
have fun reading and spray away

 

What's his setup? So basically you guys are saying that it would be safe to run a 75 shot on stock internals? I will be upgrading my fuel system, what about injectors? Also I will be changing my cams

 

A couple of years back, there were a couple stock blocked b18c1's going low low 12's with 100-120 shots

With the direct port kit, you shouldn't need fuel injectors and teh likes, but I highly suggest a progressive nitrous controller

 

A nitrous controller, or would the hondata s100 be alright?

I'm not sure if the hondata can control it progressively...can it? SOmeone please chime in.

 

hondata with the possibility of progressive control is on the very near horizen. crome and a couple others on right behind...

stock h22 will happily take 175whp worth of n2o with c16. pistons and rods weren't the problem... traction was the problem and constantly fillng the bottle!

 

175 shot wow. If I ever go that high I would definetly be changing some of the internals. Where can I find a progressive nitrous controller....ebay?

 

I looked on Ebay for a progressive nitrous controller and it was around $400. Is this really necessary? The hondata s100 controls nitrous when certain things are met, like rpm, throttle and it retards the timing. I think this is the way to go. Plus if I go boost the s100 can control this too. What are the advantages of a progressive nitrous controller to the s100?

 

it allows a linear whp addition of n2o. a regular setup adds substantially more whp at lower rpm than at the high rpm.

personally, i hate external progressive controllers. but to be fair, it is mostly because i've had no luck with them one more big unknown to add to the mix.
