STR exhaust Manifold

[Acidburn]

The company is OJZ engineering of practical performance car fame.

Although they no longer do work for Quattronics allegedly

Cheers mate gives me another option for a system.

I already told you once on MSN!

It's about £900 from them for full 3" turbo back system.

[Azman]

MIJ in Walsall said 840 in vat for a full 3" turbo back system. Considering it but want to see their work first

[Jamo]

Another prominent forum member has warned me off MIJ and I have to trust his judgment.

Anyone got flow test results for this manifold? Be good to compare it to the other options...

[Bram]

For those looking after a cheapo EM, I just noticed on Ebay a T3 version of the STR manifold. And they even improved the WG flange

however the product does not appear on the STR website, so I do not now if this is a home-made version of the K26 unit, or a prototype.

[Rusty]

Have you got a link to the STR website? I can't find it... could be an idea to look into a GB on this as I can't see that the shipping for say 5 off will be much different to the shipping for just 1.

Also seems to have popped up on Eb@y_de for rather more money... linky.

$299 on their website or...

$179 on Eb@y_com linky.

Even if that's $ CDN, that's still $235 USD @ 1.28 CDN:USD


I've emailed them about shipping multiple items and also contacted that Eb@y seller to see what shipping costs are...

It

shure would be fun to see some flow figures from this manifold

[Rusty]

I emailed the seller off Ebay about postage prices for multiple purchases. Rough price for each manifold is about £250 delivered to your door (at the current exchange rate, including all import duties and fast delivery). This would be on 3 off.

Wow I can't believe people are going to buy this log manifold, it's design is worse than the OEM S2 one which made for high EGT's

[Rusty]

Noone has bought anything yet... looking into the options.

I guess it would be comparable with these figures off the 034 fabricated manifold.
However there are some other issues that are worth mentioning. Since the one Bram bought they have indeed modified the wastegate flange to what we could call a cloveleaf pattern. They have also increased the wastegate bore to 40mm+!
So what I hear you ask? Well it means that the wastegate is no longer concentric with the bore and there is more material at the front than the rear which is the other way round on the wastegate. I would guess the wastegate has more material at the rear to beef up the wastegate where the flexy pipe is attached.
If you look very closely you can see the difference on the flange towards the rear.
Another gripe is that there is a lot of internal casting flash that will need removing. Can't see anyone wanting that going through their turbo!

Why are the EGTs higher? Is it due to the combined runners actually being narrower than the individual ones on S2 / RS2 / Wagner / tubi etc.

Why did 034 make one if they're that bad, there must be some advantage?
