Exhaust Mani And Intake Mani Worth It?

[335]

Hello

I am putting on a rb25 turbo onto my rb 20 engine and was wondering is it worth it putting a after market exhaust mani on or a intake mani? Since I will be down there in the engine, I want to go and ahead and put on parts that will help support mods.

I will be using a E-Manage and a will have a tune later and cams and cam gears,pump, injectors with that after other stuff is done. Other mods with the turbo will be a R34 smic (fmic if cant find one), split dump pipe, adj cam gears before I do the tune and cam,pump, injectors. I already have a catback exhaust.

My car is auto and I live in Japan

Help

Thanks

IMO a waste with a turbo that small, and the RB20 overall hehe

Supposedly the Rb20 exhaust manifold is seriously shocking, perhaps you could wack an rb25 manifold on there? Im not sure if they fit??? anyone??

leave the standard items. much more power to be had with the same money in other places

2nd hand HKS cast manifold would be an upgrade if you can pick one up for cheap. it will probably spool things up a little quicker. $500 or less would be good buying and certainly an improvement over stock. however, you will need to allow for manifold studs and time to do it.

quick edit: just noticed your location, might be cheaper sourcing HKS manifold in japan than one here. that might make this worthwhile but dump and bigger cat seem the no-brainer mods if you are budgeting.

I'd leave it. Save your money for turbo back exhaust.

Just had a look at both manifolds and little difference.. visually.. no point in upgrading
