S2 exhaust manifold

[z7999]

Hello there you lovely young people. I'm having some difficulty, was hoping someone could shed some light on the situation or point me in the right direction.

I've got a few parts coming soon, 630cc injectors, k26 hybrid, vems etc. Hoping for around the mid to late 300 mark.

The problem occurs where I have heard mixed opinions. I have standard exhaust manifold, some have said this will be ok, egts just may creep a little bit, just to keep an eye on them. However I have just recently read that standard manifold will only flow around 320hp.

Don't really fancy putting it all together, paying for mapping and not making the goal power, as I'm sure some of you have experienced, it's a massive pain!

Any help is greatly appreciated, apologies if it's a silly question, please go easy, still young and learning!

Thanks, Connor.

You want a better EM than the stock one if you want to go into the 300's. RS2 EM or Wagner RS2 EVO.

Agree-I would not use standard manifold.

Would 440cc injectors not do the job?

If you Google RS2 Exhaust Manifold you will get this:

Avoid the cheap eBay cast "RS2" (junk) cast clones and the welded tubular "RS2" manifolds. Poor quality and/or too many headaches (cracking etc). A real RS2 manifold will not go cheap and you can tell the difference between real and clone (or at least we can ).

L&S CARTEC were making the RS2 EVO exhaust manifold originally engineered and produced by Wagner Tuning. Good investment. http://www.ls-cartec.de/

"the cheap eBay cast "RS2" (junk) cast clones"
the STR lasting since 4 years on my friend cq, with 550+ whp

and if you would hear the guys at Wagner USA about the quality of the L&S CARTEC products you would have a totally different opinion.

Thanks for the replies guys. I will be investing in an exhaust manifold over the next couple of weeks. Unfortunately one of those things that was over looked.

As for regards to the injectors, in all honesty I've been speaking to biturbo alot, I'm just buying mostly what he suggests to make the power. I've seen his car in person and spoken to him on a few occasions. He seems very clued up to say the least. Hopefully I will make the target power, look out for a forum post from myself to see whether I do or don't haha. It's funny the amount of money we spend just to beat a friend in a race!
