Type S head onto my H22a

mills · Post by **mills** » Thu Jun 13, 2013 1:02 pm

I've got a full Type S engine from the Lude I broke, and the plan is to strip the head and transplant it into my SiR. If all goes to plan, I will pretty much have myself an SiR S-Spec

Can I expect to see any gains from just swapping the head

or will I have to look into getting a re-map

Also looking forward to opening up the Type S lump, as theres a chance there are some forged parts in there. the guy I bought the Lude off didn't know too many details, but he was told the engine was forged

Ideally you want a remap. It'd be worth considering an ATR inlet manifold before a tune as well.

for the gains vs cost i would consider just moving the cams across!

Dibs on the forged bits

why swap the head?

Also what comp does your car have? the only reason i can see to swap the heads over is for a piston swap

He has a Black top H22A - 10.6:1

Type-S/S-Spec - 11.0:1

Actually, you are right. It's the pistons you want.

well ive got the full engine, including the Type S IM, which has the larger throttle body etc

would I have to look at a different ECU for a remap

but the Type S head had a mild port and polish

is it not worth putting it on

Dibs granted

do you still want the rear ARB

do you need to do any work to the bottom end if you change the pistons

Ideally you'd probably want to go my route - P28 and Hondata S300 to get the best out of it I'd have thought.
