I've seen these adapter plates somewhere online that you can bolt to a SOHC head and your able to install a DOHC intake and exuast manifold. The only reason I ask is that I am going to be getting a settlement from work (smaller then what my laywer said originally) and I'm getting a stage 2 Hahn Turbo kit. I have a DOHC motor that is shot and untill I get it rebuilt I would like to run it on my SOHC motor. Then when the DOHC does get rebuilt I wont have to buy the DOHC turbo manifold.
Thanks guys...

 

need a head? i have one. ive never seen an adapter, that would about killairflow honestly.
put your DOHC head on the SOHC motor then youll have lower compression to run more boost.

 

The only adapter I have seen is for the SRT-4 turbo to mount to the SOHC head.
