EVO III mani ported 8cm, will it fit?

[Race94]

I am being sold an EVO III manifold ported to 8cm for $100.
Will this fit my 14b turbo?
Will it bolt up without any trouble?

It most likely fit, But you'll need a 8cm turbo gasket, and a ported turbo housing in order for everything to work properly, but if you only want to slap the Manifold right in regardless of performance, it should fit.

You're not going to be able to port that 14b any larger than 7.2 cm without running into severe structural problems. I would just get a 7cm metal gasket and then grind it out a little extra if you can. Make sure you spend some time and really port out the hole for the wastegate and also around the other side of the flapper so it can open completely.

It's great getting something that is ported that much, but however much bigger it is than the entrance to the turbo leaves room for gas to bounce back off it and slow down flow (very small amount, but some none the less). Try to get it close, but be careful how thin you make the walls of the turbo housing or it will crack to pieces.

If you haven't already, pull your O2 housing and port the snot out of it and get an EVO gasket to go between the turbo housing and the O2 housing and port everything to match it.
