Hey guys,

I know this topic has been beaten with a stick over and over, but I cant find proper information on which manifold I should purchase.

I am currently using the stock one with a break in tune of ~300hp with a GT35. Ill be looking to push this turbo as much as I can for the time being.

In the future Ill be looking at a GT45 so ill need a manifold that will suit this as well.

Should I stick with the stock manifold and just get a EGT sensor for my #6 cylinder and tune around that temp? Or should I get a new manifold and EGT sensor?

Which Manifold should I be looking at?

Nismo, Greddy, RIPS, Others?


Thanks for the help guys

i would convert to a single throttle body, no need for ITBS with a GT45... good tuning and watching plugs is key to a reliable setup

Signle TB had crossed my mind, not a bad idea either.

Would converting the stock manifold to work with a single TB be just fine? or should I buy an aftermarket one and then modify that for the single TB?

Im mostly concerned about the rear cylinder air flow.
