STR exhaust Manifold

[terrybullwon]

No idea, Jamo or TerryB usually know these things... there have been flow bench tests of lots of IMs and EMs but I can't remember if this one has been tested. Looks like a larger bore than OE but I suppose it's whether it's better than RS2, as asked above.

Yeah looks ok, You can always port it if worse comes to worse. No reason why it should not flow more than 350hp, iirc the RS2 OEM runs out at about 440?ish

At this price I'm very tempted to try it on the k24, is it a direct bolt-in job?

[k.alle]

Yes it should flow 380bhp no problem.

Since it's a RS2 "copy" it bolts up just as stock, no customization as far as I know.
I think I will be going down that route myself.

Andy, I would leave the standard on with the K24 as there will be a little more lag with this manifold

[Rusty]

A little more than none isn't very much

My EM was in good condition in November when I did the HG so I think you're right, just leave it.

I wouldnt really say it was an RS2 copy, its a log style manifold, the RS2 one looks completly different...

yes at that price it reaches the rs2 manifold when you change it every 20K,but you have to concider flanges,working hours of the mechanic,and piece of mind you wont have everytime you go WOT and it doesnt do what you want it to do(at about 20K kms...)

I'm sorry, you're right.
I meant to say that is "like" a RS2 mani, different design than the rs2 but bolts up to the oem position.
My bad choosing the words.

Well in all honesty theres not much that it indicates that it would crack at 20K IMHO.
For me that does all (almost) the work myself on the car I'm not concerned about a mechanics prices, luckily.
But I see your point, when you have to pay someone to do a job you hope you wont be there in a nearby future having him do the same job all over again which equals to $$$.

I think it's an interesting alternative however, and I think I will have a go at it when the time is right.

I'm a DIY boy too spend the money on parts rather than labour and spend ten times longer to make sure everything is clean and in good order.

i hope i had the time and knowledge to do most things on my car.I have learned many things though,i cant complain.Although i still want the important stuff done by someone with good experience on these cars,especially when lots of $$$ will have to be payed if something goes bad due to wrong fitment...

You get what you pay for with this manifold.

Lupo911 has some views on it posted on the forum, basically it's not made from the same material as the RS2 and Wagner RS2 EVO manifold and is not as heat resistant so will crack due to no nickel content.

I fitted this STR a year ago on a RS2 setup and had to problem flowing it to the max. I took it off after 10k kms, because I went the Wagner Evo way due to further upgrades of turbo (GT3071R). I saw no strange things (cracks, etc.) on the STR when I took it off the engine. You do need to modify the WG flange a fit with grinding away some material to get it fitted properly, but that's not too difficult. Cheap upgrade, with probably nice money for value if you go the RS2 route.

So what you are saying is that it's not flowing enough for the GT3071R but will do well with the RS2 spec turbo and power?
Nice to hear someone tested it on here aswell.

You always get what you pay for unless somethings on sale, then you get more than you payed for.

Yes as said before, if I'm not valuing my own time wrenching away on my car, then there is no real harm in testing it because they're so cheap.
