Twin Scroll Turbo kits?
 
I have been trying to find a twin scroll turbo kit. So far the only ones I could find are the Crawford Performance, which is an expensive all inclusive kit and JDL which looks like a tuners kit. Are there any other twin scroll kits out there that are worth looking at?

I think that's about it, thought JDL was the only one. I know full race was working on something and they have twin scroll stuff not sure if they're going that route for us.

You have already mentioned the best one @JDLAutoDesign

Unless you are willing to go really big, twinscroll is mostly a waste of money.

spool isn't much of a problem with these cars to begin with. you'll end up limiting boost electronically down low for traction regardless. not much value in a twin-scroll setup over a normal exhaust housing, unless you're going really big.

I won't be. The throttle pedal isn't an on/off switch. :lol: I can't wait to see what Full-Race has to offer. Mostly the intercooler piping routing and whether they retain the OEM fans.

good luck with that :). without traction control on finding traction with 18psi coming on at <4krpm is futile, at least for me. everything is fine up to about 12-14psi, 300-350whp. above that, it becomes uncontrollable wheelspin without smart (racerom) traction control or slower boost ramping.

I wouldn't be running that much boost, but I want it to hit as soon as possible and hold as long as possible. I still think there is value in a proper twin scroll setup.

at lower boost you should be fine... but once you start making big power traction becomes the limiting factor. you'll find that max boost at 3.5k isn't as fun as it seems on paper.

I'm going to say that twin-scroll is definitely not needed. Just thinking about all the extra work involved and extra space needed to twist/roll/weld the header primaries and flanges.

Honestly man, I don't think there's any sort of "racing" that would require you to have more power below 4k than what a non-twin scroll could offer.

I would be more interested in a VGT kit...

We sell our kit "all inclusive" or just the turbo kit, we give you the choice. And for those who are saying that twin scroll has no benefits in this car... really?
245 pound feet of torque at 2100 RPM is just plane awesome.
