Hey guys, shortly im going to start rebuilding my motor for my HSC project, in automotive class. I have a 1996 Ek1; D16Y4.

I just wanted your help and opinions on what i had in mind.

To start i planned on boring & honing the block, and getting new pistons and rings. I was thinking of using the P29 pistons if i could find some to suit the bore.

Then i was planning a mini-me conversion, using a P2P ECU, but i've found out their fairly expensive to chip, and retune, but i was opting for the P2P for the knock sensor, seeing i was going for a high CR. I didn't want OBD1 ECU because i don't plan on tuning my self, and no knocksensor. But will it be better going for a OBD2 and getting it chipped, even though its alot more expensive to chip then OBD1, or should i just forget knocksensor and go OBD1?

Also will my Y4 head cover suit a Y8 head ?

Upgrading throttle body, any suggestions on size, or what type to get would be appreciated.

CAI, any feed back here appreciated too.

And if i can afford it towards the end, i planned on getting a new clutch + lightweight flywheel. ( advice and suggestions appreciated again )



Is it worth all this, and the money, or should i just look more towards and engine conversion ? I tryed avoiding this option because, if i rebore and rebuild my engine, its all like new again, and the sense of accomplishment, where as if i engine swap i get an old engine, + im not to sure about engineering certificate and all that.


Any advice or feedback would be great
