Exhaust Manifold Query

[jeffers1987]

ive decided to change my exhaust manifold to a stainless jobby but not sure which way to go. can anyone give me the pros and cons of hi mount compared to a low mount and visa versa. ive done a search and couldnt find anything that helped me

cheers guys and oh yeah its for a rb20 running a r34 turbo hi flowed

hi mount means new dump pipe.

[jeffers1987]

hi mount means new dump pipe.

is this the only difference and hi mount purely for easier fitment of larger turbo and or wank factor??

[Wheezy]

The only reason you would use a high mount is if you couldnt fit the turbo on the factory low mounted setup.....Otherwise there is no advantage

[jeffers1987]

ok thanks for the quick replies. SAU is the shit (Y)

There will be no point in changing the manifold for just an RB25 hi-flow turbo

plenty of people (well, just about most people) get great results with the stock items.

Plus it looks factory.

IMO - spend the money elsewhere, there is far better bang for your buck

or maybe consider getting the stock manifold extrude honed...

I'd go with the extrusion hone

can you guys tell me how effective this extrustion hone is? If its any good, I'll get a second hand manifold, and get it honed - And put it back on when I change my turbo.

I post this morning in the unique autosports manifold thread which shows the b4 and after differances of flow honing a hks cast manifold

cheers Peter

lowmount = better centre of gravity

Edit/ for a race car where everything helps...etc etc...
