Looks like an MTM SQ manifold, the hole is for an EGT probe - Exhaust gas temperature

Jamo's right, how ever... Not the best place for a probe as if it melts and snaps off, its going to go through your turbine

[hoffer76]

thanks Jamo I'll see if I can get one of those egt probe kits any idea of good supplier in uk

[hoffer76]

maybe I will have it removed and welded back up them thanks

You can just blank it off, with a screw on cap. If you messure it, i may have one you can have. What turbo are you going to use wth this manifold and if you don mind where did you find it?

[hoffer76]

It seems to be approx 5mm with a course thread don't have my calipers to hand, I have a garret gt3071r and I found the manifold in Germany last year, thinking of using the 034 motorsport chip tuning package gt3071r stage 1 do you think its a good idea or not?

should of asked if manifold is suitable for desired 400hp

should of asked if manifold is suitable for desired 400hp

It will likely be fine.

[terrybullwon]

Yeah It will be fine for 400bhp, what flange is on your turbo?

[hoffer76]

I think its a t3 flange the bolts seem to line up I am a little concerned because the profile on the inside of manifold is round poss kkk27 and the turbo is rectangular as shown in pic

You need to buy a new turbo hotside with the K26 flange, Axis motorspot can get them or you can buy from ATP direct.

[terrybullwon]

Thats what i was getting at Jamo... Great minds and all...........

[Jamo]

I'm just wondering if hoffer76 could get away with using the T3 flange.........

As the manifold has a K27 flange on it and not a K26, it does not have a raised lip on it

I'd get a t3 gasket and see if the two will mate together. Lets face it the ATP K26 hotside is just a machined T3 hole to take the top and bottom lip of the K26 raised round hole.

[hoffer76]

Yes Jamo thinking the same

This is what it looks like with t3 flange there is very little interference think I may try it.
