Where can I get one of those manifolds from? I've been looking for a twinscroll t4 manifold for my RB25 but don't want to pay too much for a manifold just yet. I know you get what you pay for and I've purchased $1000+ manifolds in the past but I'm starting school back up this semester. lol

Thanks

i would have gladly gone 6boost if i could have afforded 1k for a manifold. buying a house takes priority right now though!

Stec motorsports. Not as nice as a 6boost, but it'll never crack. 3mm 321 stainless. It's basically a china made greddy copy made with really nice, thick steal.

I've had a stec manifold on my car for over 3 years now, had a motor mount break and used the turbo/manifold as the motor mount for a month before I figured it out, had it glowing bright orange more times than I can count, and make somewhere north of 600hp and have never had a problem with it. I know a bunch of people using them over here too that saw the same thing.

Ya know what? I just noticed the 6 boost isn't a split pulse manifold. While the build quality is second to none, I wouldn't put one on my car for free compared to my Stec mani. Just my $.02

i ordered that one non twin scroll...and no external gate cause i run a "ultimate internal" from atp...that mani is made to my specs exactly as i wanted so dont bang them for my personal choices...

i didnt want twin scroll cause my gt3076r isnt twin...the one i just asked ryan to make for my hx55 is going to be so it suits the turbos flange and will have dual gates...

yeah....pretty sad statement about our economy. it was't even a year ago when you could get them for that price.!

for the record even if you don't have a divided turbo the split manifold will STILL make a big difference. now if the turbo was split and the mani joined....not so much

I'm not knocking it, I'm just saying I wouldn't use that one for my application since I have a twin scroll HX40. Like I said, the build quality and I'm sure materials as well are second to none on those things. Now if he wanted to make me one split pulse with twin gates, I'd sure swap in a heart beat

kyle will make you anything your heart desires... im sure if you told him you wanted a quad scroll with 4 gates he would try and find a way to make it... the best thing is you can request a forward placement giving you more room to put O2 bungs in...and help with placement of the downpipe to make it around the steering linkage

the power from his design is in the collector some higher hp cars have seen as much as a 100hp gain just from the manifold...
