Yeah, we are going to offer a larger runner option, but it will not be for stock location turbos. We can weld on a T25 flange for the stock turbo but I think it will choke it off too much. The large runner option would be best suited for T3 flange turbo's and engines with headwork.

Alright, yeah I follow that - just would have never thought about it. Well just keep us updated!

 

[2.0t03speed]

hmm would you consider making me a manifold with bigger runners with the stock t2 flange and in stock location? im pretty sure the flange isnt going to choke anythign because mental addictions direct fit replacement manifold for the msp had 1 11/16" runners w/ the t2 flange in stock location. let me know if this would be a problem.

He says it's possible. I still might opt for that option because I plan on going with a bigger turbo and I think the larger diameter runners will look a little better (fill in the gaps some). It all depends on the collector is designed I suppose. Either way, I think I know where some, if not most of my tax return is going...

 

[2.0t03speed]

i know its possible thats not the question the question is can he do it bigger then the 1 1/2. Bigger piping isnt going to fill in the gaps that much...... Also jon your tax return has been going all over the place in the last couple months lol. 1st steed,then turbo life, now this lol. O and btw rpm you gots a pm. =)

If you cant read it, then heres a copy paste:

Thats also what I want to use for the larger tube header for aftermarket turbos....the collector where all four merge together straight down

I got measuring the 1.5" piping and it turns out they call it 1.5", but it actually measures 44mm I.D. which is 1.73 inches.

And the 1.25" pipe I'm using for the OEM replacement header measures 37mm I.D. which is 1.46 inches.

Dont ask me why they call it 1.5" when its actually bigger.....thats just the way I order it.

Weird

^^^ Good info. Exhaust piping is the same way and I agree it's a stupid way of measuring things. I mean, why call it 2.5" piping when it's only like 2.4"? But yeah, that was the other reason I'd like to go slightly larger. I also have extensive headwork planned for the future so bigger runners will help with the extra exhaust coming out of the head.

 

[2.0t03speed]

ok so now were talkin 1 3/4 runers basically good to know

 

[magnumP5]

I'm down! The bigger the better! It's gotta be good for 15 psi and higher for me.

 

[2.0t03speed]

depends on the the turbo size too your dont want somethin too big lol

True, but with a ported head and larger valvetrain, etc I'm going to need all the flow I can get. Is a GT2871 large enough?

 

[2.0t03speed]

do you plan on building your transmission?

 

[2.0t03speed]

because gtx gears arent cutting it any more. dana just broke his gtx 3rd mildly accelerating w/ only 300 hp. Boomer did the same thing

 

[Speed3.5]

You know what, I'll hold my purchase of Steed Speed many and check this for a bit longer to see what happens.

I'd go for the bigger runners even if i get the stock flange, later i could change and get T3/T4 you know.

OR :

Why don't you compare the diff. output you can get from the smaller size runner against the larger runners on "stock flange/turbo".
The result will justify anyones questions/judgment on to which one to get.

sorry guys you can count me out i found out im going to be getting my hands on a mam direct fit mani so im going to be good lol

If you don't mind , how much are you getting that for ??
