Been there seen done it, £750 of custom alloy welding to make an manifold adaptor. plus £250 for a set of throttle bodies and plenum.I'll be going S54 ITBs if I can get my hands on a set otherwise I'll use the S50 ones
Might swap the S50 tbs with my friends S54 E30 build some day when he's not looking
The throttle bodies are far to big, bike throttle bodies (I have a set for sale spaced to suit the m20) on a custom manifold (bogg brothers) cheaper and better sized.
Also my mate has a set of custom throttle bodies ofr an m20 for sale but you got to ship them from Oz
