Your best bet if you have the cash to throw around is to go to Horsepowerfreaks.com
Spend $3,400 on a brian crower stroker kit, you will be turning your engine into a sick 2.5L
then go on ebay and buy a brian crower top end kit for $1,100.


That + basic bolt ons on regular pump gas will sit you close to your 300hp

i really dont think it will above
but go for it lol

the octane rating of 93 pump isnt that good
a few people have made it but not many....280-300whp is in the race car level
it requires too much compression and too much timing...93 octane is asking for
issues..............you could build the beast of motor and use a meth injection kit...have the car tunned on the meth sprayer kinda like n2o......this way while ur driving around town on 93 octane on low throttle the meth isnt being used,,,but if you floor it then a wot switch activate's the meth and then you should be goo too go...the car will still be n/a too...............turbo guys have used meth kits for ever,,,they cruise around daily on 93 octane then floor it and hit 30psi of boost and meth sprays too keep her cool and safe.....high compression n/a builds can do the same........

make sure the car is tunned on both the meth and on regular gas....use a switch to switch the fuel/timming maps.....also keep the meth tank full cause if your on the dyno tunned meth map and it runs out then kiss the motor good by lol

i know im basing most of my ideas off of the JUN prelude. made 275 whp with JUN 11.3.1 cr pistons and only had a euro r intake, JUN exhaust and only the intake cam was modified the other was just timeed differently.


al so i thought you couldnt stroke the h because of the FRM factor?

Mike95lude

The JUN Prelude ~275hp number was crank HP, not at the wheels btw. Realistically, that car probably made no more than 230-235whp.

ok, well with the right tune and parts could i make at least 275 on pump gas?

goldluderay

you can still stroke the h w the frm sleaves.....you just have too use a frm compatible piston....and make sure you check every clearence

jspinn13

hmm... ok ill start looking i mean if im going into the higher horsepower range shouldnt i just get better sleeves? then i could stroke it with any piston right?

dude, after reading this, you should stop modding the car and research a lot more before you even consider this.
The guy up there saying drop 3400 on a stroker kit is nowhere near the total cost of that build. You still need to resleeve the block. Just run the h23 crank and go 89mm.
That will get you 2.4L.
Those frm compatible pistons don't have anything higher then 11.5:1 I believe unless they make them custom to order.
I'll be shocked if you reach 250whp.

jspinn13

no i havent modded anything yet, i have really bad compression in the engine and i was just going to rebuild to stock... but why do just that? i may as well build it for boost or build it all motor. i was leaning for boost and then i thought it would be fun to just beat all these little civics running turbos and that (thinking they are fast) and be like yeah im just all motor dude, so i wanted to do all motor. either way i need to do something to my engine in the form of rebuilding it soon cause i dont think its going to hold much longer the way it is

JUN is way over priced. Im building an All motor h22 for my 95 w/this years income tax. Fully built block (mahle 11.5.1 pistons w/eagle rods, bearings etc) and a fully built head w/Skunk2 internals/port n polish ported euro IM and my total build should run me about 5300. W/a good tune 250 is easily doable on pump gas. If its a DD u dont want to go over 12.1 n even thats pushin it. Do more research n dnt go spenidin so much money bc its jun. Research shows skunk2 to be an almost identical profile for their cams. Euro R IM has been proven time and again that its the best for h22 (minus sk2 for boost). Im also gonna be sprayin a 75-100 shot on top. but ur numbers are insane man. 14:1 is ****inc crazy. Sit down infront of ur computer and dnt talk to anyone and just research. Ive got hrs n hrs nhrs of research into my build and i havent started yet. 250 is doable but difficult. Not cheap. But ya gotta pay to play

FS/FT:JUN H22a1 220+whp longblock, SSR header - Honda-Tech

and go from there if you want more. This here is basically a full JUN build

Honestly, it'll cost way too much to make the H22 pump out anything over 250 whp. If you planned to track your car, more power to you. But it seems like u just want a little extra power for the street. If you want a fast car to beat those little turbo civic, get some suspension mods and take them to the canyons and you'll see why you picked the prelude over the civic. Also take into consideration that a lot of those high powered h22 runs itbs.

jspinn13

yeah i think what im going to do is rebuild it (blew a piston) make it a lower compression and sleeve is and boost it, i have a friend with an accord and hes pushing 600 hp with his new turbo manifold, i dont want that much but i do want to make about 300. and it seems like that is the easiest way to get there.

keep in mind one of the most important things about forced induction is the tuning. do not skimp out on your engine management system or your tune! also, do not drive around without a tune.
