ive been searching and trying to find out what is needed to be done to fit a fd mani on a TII block. i understand that it will work but i cant find out what exactly needs to be done. im looking to use a FD HKS cast iron mani. on my tII. im doing a full custom turbo install, so the downpipe and intercooler piping will be custom done anyways. if u guys have any info that would be greatly appreciated as i cant find it. thanks

 

you'll need a spacer or the turbine housing will bump the lower intake manifold.

or you can use an on-center turbine housing, but they suck.

 

alright thanks! thats all i needed to know
