im just lookin for some help on what parts im gonna need, i wanna build a f22 boosted to make around 300 whp, i planned on arp headstuds copper headgasket, bisi turbo cam bigger injectors but what size turbo does anyone recomend? and what should i boost it too to reach my goal? the car is gonna be a track car only and will be raced only on weekends so im not lookin for a daily driver reliable car, thank you for any help guys.

There is another thread on here of a f22 with 4g63 stroker pistons and h22 rods.. https://honda-tech.com/forums/honda-accord-1990-2002-2/turbo-f22-build-h22-rods-4g63-pistons-low-compression-2546957/

I would go with a Precision turbo or talk to shodan hes the man that knows everything about turbos, but I would look for a t4 exhaust side as f22/h22's will flow alot of air.

You will need pistons before a cam. All depends where you want to make your power and how high you want to build your motor to rev. The smaller the turbo the faster it will spool and the lower it will make boost.

ok, im lookin to make max power around 7500, thanks for the input im gonna check out the 4g63 pistons and rod setup now too

Dam you really want to rev that f22! Get a big turbo then.

Depends on what he is doing. A cam is cheaper, and will result in more hp per $ IMO.
The exhaust ports are a limiting factor as well as the intake manifold. Redzcstdhatch was revving these things over 8k last time I was in his thread....

He will need pistons for this thing to last. A cam not so much.
The f22a head flows the best. I would say get one with a port job, dont use the f22b head it sucks. You can also use a h23 intake manifold with the f22a head.

Any varient of f22 is pretty decent base really for that power level, f22b1 or f22a would be my first choices though. (Some people dislike the f22b1 but I would disagree with them... it has plenty of potential)

ARP headstuds are a must in my opinion for a boosted f22 application, at the least they are cheap insurance vs stock headbolts. For the headgasket just run a OEM multilayer, copper headgaskets are not for this application.

Cam, a simple webb/ bisimoto regrind is decent place to start. If you go f22a, I believe delta is also doing some decent cams.

Turbo would depend on what your budget is and if you plan to make more down the road at some point, for only 300 you do not need anything very large. Not knowing your budget and assuming you might want a little more down the road, a GT30R varient sounds like a good fit.

You need to look into quality management as well... definately plan it in the budget, not as an afterthought.

I don't agree with the piston statement. A set of new pistons/rings is more then picking up another running bottom end from a junkyard. Over on CB7tunner there are plenty of people running around @ 300hp that don't need new pistons.

Thepowderblue

You are wrong, Everyone over there brakes there ring lands on stock pistons, new or old. I should know because I am on there all the time.

Thepowderblue

This is a good one http://www.cb7tuner.com/vbb/showthread.php?t=189224
92smokeaccord had busted the ringlands with as little as 5 psi on 5 low mileage block. They didnt stop braking untill he put turbo pistons in.

You understand that, internally, an H23 is different from an F22 correct? That post holds no merit. I'd even go so far as to say a shitty tune may have been the culprit. While I'll agree that the ringlands are the weakest point on a F22, there have been well documented stock bottom end setups that have seen 300+ for a very long time. Personally I've run between 6psi up to 14psi nowadays on stock 178k mile pistons. F22s are a very stout powerplant and an excellent choice for boost. Anything under 10psi is typically ridiculously reliable with good numbers to match with a GOOD CONSERVATIVE TUNE. The higher you go over 10psi, the bigger your ***** ought to be and you'd better have a spare motor handy. It's been discussed and beaten to death. Just search and you'll find. See this:




While I'll agree that the F22A6 head is the best choice for an OEM setup. F22Bx heads are not junk. An F23 intake manifold, H23 throttle body and some porting will go a loooooooong way.

Thepowderblue

If you port any head it will flow, the f22ax flows the best. I say f22a because you can also put a h23 intake manifold on it. The h23 intake in the best intake we can put on f22's.

Blaze45

I simply stated that I don't agree with your statement that the OP WILL need new pistons. IMO, he doesn't for weekend only 300whp track car. You are entitled to your opinions and I mine.

H23 not an F22. There was no mention that I saw as to how or who tuned the car for 10psi, but I didn't read the entire thread critically.

QFT.

this is great thanks guys, what size injectors would 550cc provide me to 300whp or should i go bigger, what about a 16g turbo? would that provide enough boost? i have a low mileage f22a1 now and a extra h23 manifold and a bunch of h22 parts, currently im running a h23avtec bluetop in a 92 civic hatch at the track and it screams weighs in at 1255 pounds.... power to weight is incredible.
