Got my new hatch. 91 si. came with an a6 with new valves and the head is trimmed a little so its a little higher compresion.

i was going to sawp my jdm zc (sohc vtecc) in. but i didnt want to have to go thru all that emission shit and get kicked out.
chipped ecu came with the swap

this was my plan. i was just goin to leave the a6 block in and put the zc head on, run my vtec wire, and be gone


goal: reliable boosted dd. 8-10 lbs.

(either way the a6 block has to be in the car)

QUESTIONS.

1. would i be better off swapin the pistons and rods from the zc into the a6 block too?

2. which internals would be better for boosting? (crank/rods/pistons)

3. will either of these internals hold 8-10 daily.

4. if i do leave the a6 block as is and just throw the zc head on wont that retard the timing? 4.5 degrees i believe?


cant think of anything i left out right now... probally did soon as i think of it ill let you guys know.

Kind of a what route would you take thing. /best route.
Feedback please.

appriciate you guys help.

Everything revolves around how much power your looking to hit, then you base what your engine can handle and what your going to need to upgrade in order to meet that reliably. Stock rods are good for 200hp so if your looking to go over that upgrade your rods.
