ST205 Exhaust manifold WRC vs Stock

[benj]

Can anyone tell me if their are any differences between the WRC version of the exhaust manifold and the stock one apart from the non-functional antilag piping?

For example is the casting of better materials? Lighter? ported/polished? bigger internally for better flow?

Cheers

Richard Doig, who is "Running Rich" on this site would definately be able to tell you. There are some pictures on his site:

I don't think there are any internal differences though, after all the WRC has the same power output as a standard car. I'd also be suprised if therw were any differences as the standard ST205 manifold is very good- Fensport in the UK say they have seen Japanese cars still using it at over 600bhp.

You might also want to read "Redmist's" project diary- called something like fat cat ST205- he had a play with the WRC manifold and ended up getting it operational by smashing a certain part with the hammer.

No difference as far as I'm aware (apart from the anti-lag of course).

theres a WRC exhaust manifold and a " WRC " one from TTE thats better again ..

they are also no longer made - and fennies managed to use most of them ! bastards * chuckles *

besides the plumbing for anti lag they look identical . They just make our cars more special for an extra gadget to play with if we want to !
