Question about exhaust manifolds

[S2central.net]

In my quest for a cost effective supplier of a modular 3" stainless exhaust system - for Coupe initially - I need to know if the S2 and RS2 manifolds position the turbo in exactly the same position. I've never had two side by side on the bench to compare.

Also - does the Wagner RS2 Evo manifold line up as per RS2 locations ?

Reason I ask is to ensure that the downpipe is suitable for those three applications as a minimum. I guess one way to know is if the 70mm downpipe from RS2 can be bolted directly onto S2 manifold and stock turbo. Anybody BTDT ?

I will have a flexi section incorporated at bottom of downpipe so there will of course be some room to adjust for dimensional variance.

I'll post more info when I get it... I may have a road trip to get this sorted properly.

all i can say for sure is that the RS2 EVO manifold is made to be an excact change from the RS2 manifold

[s2_bo]

Yeah, oem rs2 and evo line up exsactly the same.

Cant say i have swaped all 3 including the s2 one around in a row though but i would imagine that they are all the same.

OK - cool - I figured as much... Just needing the independent evidence you know !

I'd hate to go to lengths for a generic downpipe then find its all wrong when upgrading from S2 manifold...

Had them side by side and didnt notice any difference. Turbo housing might have an effect on position too.

Just remembered... I have an old K24 and S2 EM in the secret spare stash... And an RS2 turbo (perfect except for cracked hotside housing)... I'll do some investigation.

The RS2 downpipe bolts straight up to the S2 manifold as well did it last week. Hope this helps.

@Lee - was that with S2 or RS2 turbo fitted ?

[Big Lee M]

Just the standard S2 turbo.

Thanks - we are getting warmer

You have an rs2 turbo in the secret stash? Thats like saying you have £500 under the floorboards in your kitchen...
What a waste

[S2central.net]

I most certainly have a stash - in different places - worlds slowest project you know... Almost getting to critical mass with the major bits and the motivation to really make a start. If only I could fix the damn water leak then I'd feel good about doing the go faster thing.

PS - How much for a Wagner RS2 Evo EM by the way ? That is one big lump missing right now... I already have the Wagner IM in another stash. Sneaky aren't I ?

You'll be on one of those generic antiques shows like cash in the attic with them before they get on the coupe

Secret stash doesn't suprise me... you've been at this a while. I've just got bits for the track, if you want to go faster, take some brave pills beforehand!

Your probably right Andy... was planning it more for a 'fun' engine build project that could be roadtested and tracked awhile before selling it onwards for someone else to get better use out of - seeing as my car is somewhat dual purpose... BUT if I can work things that the Coupe becomes a proper low mileage weekend toy then the bias of sensible compromise can be swung out the door.
