Default DOHC ZC 1.6L What parts do I need to upgrade.

Thanks to everyone that helped with my past questions but heres a new one. I want to beef up my Dohc ZC internaly. What are the best parts to run and where can i find them? The car will normaly be used for a DD but i want it fast enuff to beat my buddies that are all pushin alot of HP. I would also like to run a small turbo too, so keep that in mind before suggesting parts. The car its going in is a 89 CRX si. If the pm6 ecu can be used from my crx it would be nice since its already chipped.

Get rid of the chip first off. Its prolly doin more harm than good, and the chances of it really being a mugen are super slim. Get a PG7?? i belive thats the teg ecu.

Yes, get a PG7.

Internal upgrades are kinda pointless unless your making it stronger for boost. If so, Pistons and rods should work wonderfully. Click the image to open in full size.

ZC rods aren't so great, look into upgrading with B18A/B rods, they are much more stout, many racers use them in "d" seires engines.

BOTTOM END components

connecting rods
88-91 Civic/CRX Si 1.6L
But any D-series 1.6L rods will work for upgrading.

Pistons
88-89 Integra OEM
There are many companies that offer ZC specific Pistons now, so Aftermarket is there.

Main & Rod bearings and thrust washer bearings
88-91 Civic/CRX si 1.6L

Piston Rings
88-91 Civic/CRX // 86-89 Integra

here ya go......

Dont rev that **** to 8200 rpm for 2 reasons:

1. Your engine will blow up

2. Your peak power is at 6800


Get a good tune and run more boost. Rinse, repeat.
