I have just built an engine with sti version 4 heads so I have to change my inlet manifold for a version 3/4 as the inlets are different shaped but the engine is go in to a impreza version 5,but the throttle bodies are different from v4 to v5 shaped to,but I need to keep my v5 throttle body and all my auxilliries off the version 5 inlet maifold because all the electrical connectors and coil is all different.Is there a way around using my v5 throttle body on a v4 inlet manifold,or do any1 do manifold coverters v1.5 to v2 inlets like carl davey but the opposite way?I thank you in advance for you replies!

 

either alloy fabrication req to fit the v5 body mount to the v4 inlet or get an adaptor plate made to do the job, an alloy machinest could do this eaisly
