Hey guys quick question..

My car is a bb4 and with a good service and full exhaust system and decat and induction kit it produced a healty 208bhp and 152 torques..

I will be fitting a h22a7 head from an 51 plate atr..

What sort of gains should i expect?

The head will be getting skimmed.. i don't know what else my mechanic was talking about but he also mentioned about doing something to the valves or something Embarassed

sorry if it doesn't make too much sense but i was trying to do something while my mechanic was telling me all this..

Anyways.. what do you think the gains will be then?

I had the excat same idea about getting H22A7 head on my H22A5.. But after the conversion you will need a ECU upgrade i think... Idea

AFAIK as its a BB4 with an OBD1 ECU, it can be re-mapped to take advantage of the ATR head.

Only the OBDII ECU (5th geb ludes) can't be remapped.

I'm sure someone with some knowledge will tell me I'm wrong though. Laughing

Oh yea i forgto the guys with OBD1 will only need a remap. My ECU (OBD2) will need a ECU upgrade...

i am not to much bothered about the ecu as i have other things planned for the engine before i remap it.. but just the way the ecu is at the moment will i notice any improvement at all?

I reckon you should defo feel the difference as in the A7 the valve setup is higher so u will feel it more.. If you get what i mean... im no mechanic btw Embarassed

thats what i was thinking off as well.. plus the fact that the atr engine revs up to 9k rpm.. and also vtec kicks in at 6000 rpm....

That'll be using an ATR ECU though.

Cheers mate... Wink

What does the £400 include.. I know its just Head transplant but what does it actually include. Embarassed

Sorry if this is a dumb question... Embarassed

none at all m8.. it includes taking the existing head off and putting the new one on, and a new head gasket for the h22a7 head.. also something the mechanic is doing with the valves or something.. and most importantly of all test driving the car and making sure everything is working fine..

i am hoping it will be producing a healthy 220 bhp when the new head is on..

yes..

it's defintely worth it in many ways as the h22a7 head is from a newer and slightly more powerful h22 series engine..so thats means that any mods that you do to your car you will see more potential as you have a better engine base..do you know what i mean?

Yes i get what you mean... Cool

Why dont you get Adjustable Cam Gear aswell coz seeing as his taking the head off and also the Tunner can tune the CAm gear and you can probably get more then 220BHP afterwards... Idea
