Hi.. I am researching a turbo kit for my car and have read about people using the L26/l36 Intake manifold compared to the blocked off M90 case. What are the benefits to this setup compared to the M90 casing?

Mot of the GTers use the stock L36 UIM....but..the L26 UIM wont shatter under HIGH boost.......

the L26 is a better option....and with a little modification will fit onto the LIM of a L36.

the blocked off SC housing is what most SC cars do...as it is little to no modification.

if you were to add the LIM from a L36/L26....onto your L67/L32....you would have extra injector ports...as the L67 fuel injectors spray through the heads.....

you would either have to block these ports off....or it would be a good time to add a direct port nitrous kit ontop of it..lol depending on how big you want to go.

Tap the LIM and use threaded pipe fittings, its' cheap and easy (If you don't want to use the spray !)
