How to turn a F22a6 to Vtec?

[CBWagon]

What head would i need to turn my engine to Vtec? will I need to rewire anything or even get a new ECU?

[NorcoAccord]

you will need an H22 head or F22b head, you will need to modify both head i.e. coolant passage and maybe oil passages, check in the swap section about doing the H22 swap and also do a search this issues has been covered a few times and pretty much everyone agrees its not worth it.

Like deev would say, "don't get fooled by vtec" and he'll also go on to mention that the F22B1 engine with vtec isn't worth it as it has horrible head flow.

if you truely want vtec and performance, look into doing a H22A swap. By that i mean swapping out your A6 engine for that prelude engine.

So doing a head swap is not benificial like as if I were to put a Vtec head on a LS block... for LS VTEC as a oppose to GSR (LS VTEC usually comes with a little more Torque

^^^^^^ way easier then trying to turn a non-vtec motor vtec

Turbo the A6. Fuck a H22

VTEC involves a camshaft with two profiles. It incorporates an entirely new head design. The F22A head can not be converted to VTEC.

To properly turn your engine to VTEC, you'll need to take it out, set it aside, and put in a different engine. A headswap is possible, but the gains aren't really worth the added risk and lack of reliability. SOHC VTEC is worthless, DOHC VTEC is not worth a damn on a stock F22A block...


Leung, you know me well It's nice to know that when you say something enough, soon, people start to say it for you!

I cant say SOHC Vtec is worthless but its true amongst the F-series

I dont get that either. J series = SOHC vtec.

[Zer0_92EX]

the F-22 is where its at man, save your money thou. if you really want VTEC go H22 like everyone else says. u cant deny the 200 hp

[CBWagon]

Well I was looking at the financial point of view... I'd figure that the head swap would be a hell of a lot cheaper than a full motor swap... what horse power gains would i be looking at if I just did the head swap?

[Zer0_92EX]

u cant put a h22 on f22
h22-DOHC
f22-SOHC

cheapest way to get your car faster is to buy everthing else like a FULL exhaust, intake, weight reduction, ECU programming, and other things.

and as for cheaper engine, just buy a JDM F22 and mod it. its cheaper and ull save ALOT.

i like my f22b1 engine, well i got it for free

[deevergote]

Oh, ALL SOHC VTEC isn't worthless... but SOHC VTEC I4 engines are worthless... at least as far as we're concerned (go ahead, put a D series in your Accord... I dare you)



As for putting an H22 head on an F22 block, you can do that. The number of cams has nothing to do with it. The reason why it's a bad idea is that the F22A has considerably lower compression, and isn't made to rev as high as the H22A head would require (it CAN do it... but it's not designed to... and it's old and tired... Generally just not a good idea!)

Minimal gains. Not worth it.
