all motor f22a6 build

[djscoonf22A6]

so i am planing to build my f22a6 all motor so fair i have a h23 M2s4 tranny
headers pt6 ecu intake my goal is to get 170hp any ides .......

You only need one header.


How much work do you plan on putting into this motor? Do you expect it to be reliable? Do you have a budget? 170whp is actually not very difficult... but to do it right, it's not terribly cheap, either.
A Bisimoto header, Stage 2 camshaft (with necessary valvetrain upgrades), a good intake with a quality filter (AEM, K&N, Apexi... no cheap shit.), a 2.5" mandrel-bent exhaust with a free-flowing muffler, and a carefully tuned P06 ECU should get you pretty close.

what kind of whp do stock hondas make compared to their rated bhp? is it even close?

[deevergote]

A 15%-18% drivetrain loss is usually assumed... so an F22A6 that makes 140hp at the crank is putting down roughly 115-120hp to the wheels. That is assuming the engine is healthy and running correctly... Seeing as they're all about 20 years old now, it's not unreasonable to expect 100-110whp, realistically.

With that in mind, we're potentially looking at adding 70whp... that's quite a feat, honestly! Easily done with a full rebuild and internal upgrades and modifications... but on a stock block with bolt-on bits (as I'm sure the OP is planning...), it may be difficult. It also may blow up under the strain of nearly doubling its output on 20 year old parts.

i think you can get close to 30 hp without changing to higher comp pistons but you will sacrafice a lot.

im talking bisi header, stage 2 cam, itb's and freshening up the motor. numbers are great foro bragging on cb7tuner or talking with your friends, but it's all about how you put it down.

[deevergote]

I don't think ITBs will be necessary. An H23 intake manifold will suffice.

[SOHC-FTW]

ITB's and a $700+ header are a bit over board with his goals.For a 170whp setup heres what i would do....
K20A2 piston's 86mm bore(so you will need a good bore performed).
Fresh rebuild top to bottom.
Bisi lvl 2 cam or something thereabouts.
Upgraded valve train.
Ported exhaust ports.
H23 intake mani/tb.
Decent bolt ons I/H/E.
And a good tune.
This set up might blow your goals out of the water aswell as fuel milage, but is decently cheap.Should cover you goals quite nicely, but could and will get costly if you can not do the work yourself other than the machine work.

[deevergote]

I'd go with the $700 header over replacing the internals, personally. Especially if he's a beginner, and will be paying someone to do the engine work.
Increasing the compression ratio and doing some work to the head is certainly beneficial, though.

You might, but i just wouldn't nothing against the product at all.For that money I would go internal and see much more beneficial gains for less.
On a serious setup (250whp+) that header would be worth it to me anything less i would have to pass.
Any build for a beginner is going to be rough no matter what, but i see what you're getting at though.

[deevergote]

The internal work would cost more in the end, though. Granted, rebuilding the engine WOULD be wise.

HondaFan81 had a worked head and a crap header, and 170whp was about all he was able to get out of it. Since the Bisimoto header adds nearly 30whp by itself, untuned, I'd think that would be one of the easiest options to bring the OP near his goal. The header alone would result in about 145whp, I'd imagine. Only 25 more to dig up with the intake, intake manifold, exhaust, camshaft, and ECU tune.

How much would all that machining work cost?

Let's say..
bore
exhaust ports
and possibly the intake ports and IM/TB

Here near me it can be $20-25 a cylinder so roughly $100bux.Pistons $100-300 ($100used/$300 including the pins and rings)getting wrist pins done is about $40 bux give or take.
Roughly $450-500 on the high end to do all of that if you can put the engine together by yourself.
As for porting i don't really know $200-500 is a guess on the IM and exhaust ports.

Now adressing the bisi header on such a mild setup like your talking about deev you probably won't see 30whp.Maybe on bisi's sheets,all dynos read different and are basically a tuning tool for the most part.Look at beast dyno comparison on his bolt on f22a set up he gain 10whp with the bisi header compared to the DC.
With a fully built F22 you would see great gains from his header.

[mtnbikaah]

The header alone would result in about 145whp, I'd imagine.

The Bisimoto header won't give you 26.9whp at peak horsepower. That 26.9whp (maximum gain) is at about 6000rpm (about 110hp).

At peak the bisi header is about 8.5whp. (118whp or so)

That's if I am reading the bisimoto stock f22a1 graph...

[deevergote]

That is true. Engine condition comes into play as well, and I'm sure Bisi chose an F22A that was in perfect running condition. Not all of us have perfectly running cars.

Headwork usually runs about $600-$700 from most reputable shops I've seen.

Honestly, if I were to open up the engine and have the head modified, I'd be going for a much more extreme build... and I wouldn't waste my time with OEM parts when I could use stronger aftermarket parts. More expensive, yes... but for all the work it takes to rebuild the engine, I'd rather use stronger parts, and have more control over my options.
The tables have turned! (now I'M the one saying "if you're going to do that, you should raise your target HP to justify the work!")

[SOHC-FTW]

Full head work yes, but not just the exhaust sides of things.RLZ will do a head that is good up to 500whp for around $800.
Now about the A2's they would last.They're Many strong stock block k series out there.Plus a 3 point bump of compression isn't to bad for around $500 im the kinda guy that likes doing stuff like that.But i can do my own engine work for others who can't of haven't learned yet even a rebuild can get expensive at a shop.
And yes lol it might be overboard for his goals haha, but still a great mild N/A set up for a street car for not so much money.I'd say it would be worthy of 200whp give or take.But it would make his goals easier to achieve with less.
