Lightened flywheel and porting advice needed please.

[Cooch]

Right brought an Engine from ebay a little while ago to rebuild and think it must be an auto as it has a rear counterweight (correct me if im wrong) so this means i can run a lightened flywheel. Correct? Also i know i cant got mad but how much can i fettle the ports on a standard ECU and twins? Can i just give them a slight polish i.e get rid of the casting marks or can i go a little further? Thanks in Advance.

I wouldn\'t touch the ports on a stock management system, you are asking for issues. You could replace the rear plate with a manual rear plate while the engine is apart.

get yourself an Apexi Power FC

What difference will the rear plate make? Am i on the right lines with the rear counterweight though? Wont touch the ports then. Lol

[BlitzBoy]

yes you can add an ACT lightweight flywheel if you have the counterweight already

[Cooch]

I dont know what make the flywheel is. Does that make any difference?

[BlitzBoy]

no if its a proper lightweight flywheel for the FD

[Cooch]

What do you mean by proper? Its a lightweight flywheel for an FD.

[BlitzBoy]

I meant if its designed for the FD

Timtook me out for a spirited drive (not that he knows how to drive any other way) in an heavily ported single turbo white rx7 on stock ecu. It went like absolute stink, must of done about 20+miles in it running 1bar boost.
Would necessarily say it\'s recommend but boy did we have fun.

We got back to his workshop. How we got back in one piece is beyond me.
I did eventually come to my senses and fit an apexi.
