I should have just gone with ITBs, it's less work. :P

Most of this comes from my F2D F20B build http://honda-tech.com/zerothread?id=1638988
but I figured that I'd help you prelude guys out :thumbup:


The first thing that I started on was the euro R single runner manifold. This thing by far is the biggest hassle. It requires lots of modification, lots of adapter plates, and lots of attention. I dunno what honda was thinking when they made this thing. Heres what has to be done:

Fuel rail modfication
Throttlebody modification
IACV adapter plate
EGR blockoff plate (or just bolt an unplugged egr switch on there)
Grinding away some material from the IM flange
Blocking off some ports for air injection things
Turning the brake booster hose nipple towards the LHD brake booster
modifying the injector ports

In fact, the only things that is about the same on this and the stock manifold are:
The runners actually line up with cylinder head.
Throttlebody bolt pattern is the same.
