:confused: Hey its FKJACCORD!
Havent been here for a while! Hope everyone had a enjoyable and safe easter!
The title says it all..
i know for a fact that i will be turboing my accord soon..
but ive asked around and i have had different perceptions for either turbo the f22b or the h22a.

I want to run @least 8psi boost?

Ppl have said i cant run more than 6 - 8 psi on the h22a? is that true.. (stock block) and i could run about 10psi on the f22a (stock block)

I guess ill be asking the following?

How much would it be to turbo the block with a t3?

Thinking of getting the setup @ www.turbo-kit.com (http://www.turbo-kit.com/) are they good there?

How long does it usually take to get it installed?

What psi boost on what enigne is safe to run? f22b ??? h22a??

And

How much is it to get it engineered in VIC?


Hope you guys can help me out cause im pretty new to all this turboing... on hondas..

Thanks for your time!

if you run the H22 at 6psi (stock block) youll make more power and be able to utilise it more if your H has an m2b4 gearbox which comes with LSD, than if you were to run an F22 at 8psi.. the F has open diff so youll just be spinning the tyres. the H will be able to get more traction but is a more highly comp engine, so you will want to have it tuned very well. the F's internals are lower compression than the H22 so it can 'handle' higher psi in theory but with the right tuning the H can handle the same pressure, as has been proven in the states.
turboing the F22 is a cool idea and not widely done, but strapping on a turbo and running around 5-6psi will be making the same power as the H would NA stock. that power would also be harder to put to ground as it is an exponential increase in power on an engine with an open diff and FWD, both negatives when turboing.
if you want high psi numbers, go the F22. if you want useable power rather than the cool factor of high numbers than go the H22. both engines prob wont be able to put the power to the tarmac until end of 2nd or maybe even 3rd gear but the H will have more of an advantage getting traction thanks to its gb.

and i'll give a different opinion ;)


be able to utilise it more if your H has an m2b4 gearbox which comes with LSD, than if you were to run an F22 at 8psi

you can always use the same gearbox on the F22, or even better use a better LSD in the F22 box


the F's internals are lower compression than the H22 so it can 'handle' higher psi in theory

not quite...lower compression just means a higher margin for error. The reason the F22 tends to be able to handle higher boost is the strength of the internals (ie h22a has a ringland weakness for example)


but strapping on a turbo and running around 5-6psi will be making the same power as the H would NA stock.

you'd run 10-12psi...there is no point in just running that low boost. In which case, you will make considerably more power and more importantly a crapload more torque.


if you want high psi numbers, go the F22. if you want useable power rather than the cool factor of high numbers than go the H22. both engines prob wont be able to put the power to the tarmac until end of 2nd or maybe even 3rd gear but the H will have more of an advantage getting traction thanks to its gb.

As before, the gearbox can be used on the F22. A quaife LSD in the F gearbox will be even better. At the end of the day it will cost you 3-5k more to put the h22a in first. That money could be used for forged internals plus LSD on the F series which would see you making far more power than a stock H series turbo and putting it to the ground better.

So now you have arguments for both to consider :)

perfect argument.. H vs F lol

i was measuring turbo set-ups on stock engines only, with no mods other than those needed to run the turbo kit.
if you do the mentioned modifications to the F, yeah it will be able to get traction. the F can handle more boost as the sleeves are a fair bit stronger than the H's, that said if you spend the money to upgrade the internals of the H of course you will have to purchase sleeves to match the desired pistons + rods. the H will make more power as it is dohc and overall is a much better performance engine than the F.
not saying the F is a good engine, the F as a street setup would be cheaper than the overall costs of having to swap the H in then turboing it.
IMO if you want turbo, do the F as it will work out cheaper and you can make some good numbers from it.
if you want a hardcore drag motor and money is no option go the H.
the bottom line is always money, and at the end of the day if you do the same mods to the H as you do the F the H will make more as it is DOHC and is why the engine is used in most of the worlds top honda drag cars

couldnt agree more with that :)

J-specAccord and POid!.. thank you so much for your time and effort in debating on the questions i had... it has helped heaps..

i know what to do now so... thanks again!

poid i know we've spoken a couple of time over the net.. i guess this time has helped the most thanks mate...

a turbo manifold with td04 off a galant vr4 with will bolt straight up to the f22b engine.

the kit will cost about $3,500 before shipping

whether or not its good....no idea...looks ok from the picture hahaha

have you contacted them to ask about shipping and warranty and all that jazz

let us know if you go ahead....and who will do the install etc.

no it wont...it can bolt up to the f22a but not f22b (i think you need to redrill a bolt hole or two for the f22a, thats about it)
