Build questions
What's up scionlife, I've got a few questions that I haven't been able to find the answers to in my searching so figured I'd ask you guys. I'm in the process of a major powertrain overhaul that includes a ptuning longblock, 5 speed swap and new turbo kit for me. My main goal is to hit anywhere from 400-500hp The questions I have though are as follows, and any input is appreciated!
1. At what power level do the Oem axles fail? I'd rather not have to buy a $1300 pair of axles if I don't need to considering I blow thru cv boots atleast once a year from how low I am.
2. Based on my goal power levels, I'm assuming my torque will be at or near the 400ish area, and I haven't been able to decide on a clutch. The car is my daily so I'd prefer something relatively driveable (I don't see much traffic in my travels btw) so if anyone could point me in the direction of a reliable clutch or has experience with clutches for that power level would be of great help.
3. I would really prefer not to run the stock intake mani (and I think I read in the past they fail near the 400 mark) so since it appears that descendant no longer makes their IM, is my only option the weapon r? And if so what kinda power can they hold?
4. Lastly, gt30 or gt35? Dual or single wastegates? I'll be running the ptuning kit but haven't been able to decide which turbo I would want and wether or not a dual wg setup is needed.
Again any input is appreciated, and thanks in advance!

1. Those axels can easily fail at 400hp. DSS should make some for your car for much less than 1300 a pair, and those are good to almost a 1000hp
2. Twin Disc. Any other stage will not hold those torque numbers for sure. Driveability will go down dramatically, but you gotta do what you gotta do.
3. Intake manifolds aren't about power, they are about boost. And yes, you will have a lot of boost at the numbers you want, and the stock one will not hold. The weapon-r one is the way to go, and again, it's not about how much power it holds, it's how many pounds, and it holds 50lbs.
4. I've seen plenty of 500hp cars with gt30's because of the right turbo kit and fuel system. Otherwise, a gt30 is normally seen in the lower 400hp range. I'd go with gt35. You're getting a PTuning kit which is a nice kit and should be able to spool that bad boy with no issue, so I wouldn't say that the gt35 is too big. I think it would be a perfect match. Otherwise the gt30 will be a quicker spool but might not have the up-top that you want. And you'll just need a single wastegate, a dual is certainly not needed for this set up.

1. Unfortunately I haven't seen any other dss axles for sale that are under that price. Ptuning has dss stage 3.9 axles that they say will hold 600 and they're 1300 and dss website only has the 3.9 axles as well so if they're out there for cheaper I haven't seen them.
2. Would I really need to go all the way with a twin disk? I've seen act has clutches that supposedly hold 500-650tq, along with comp clutch with some that hold mid 400 but I've heard terrible things about them.

1. That sucks then. I have stage 5.9's and I didn't think they were even that much... hm...
2. Listen, 500hp is nothing to play around with, and with the torque that follows, that's nothing to play around with either. At those numbers, you're just looking to break sh.t left and right. To be safe, I'd go twin disc, to have that piece of mind that you'll never ever think you might have felt a slip. With some of those others, you just never know... That's all. ACT is the way go to with the tC though, if you got that route. They have their sh.t figured out, however you might need to adjust your push rod to get it in gear, that is the only problems I've heard with ACT.

Have a few thousand miles on my Competition Clutch Stage 4 and it is still holding up. Im going to beat the living hell out of it as soon as the track opens and Ill keep you posted as to how well the new Comp clutches are in the Tc in regards to racing.

If anyone happens to have a line on some not rediculously expensive dss axles I'd appreciate the lead!

stock manifold is fine. as far as clutch act makes great one'd to hold any power levels. i have a twin disk and its annoying. also 35r but going to need a built head to get anywhere near 500 whp pump gas. if your using race fuel u should hit your goal with stock cams. also a nice fuel pump and most important goos a** tuner

Gates, IF you want to run REALLY low boost like say 4-6 PSI on that GT35R, then get two gates. If not, you'll be fine with one IF the gate priority is good on the manifold.

last year i made 430whp at 23psi with pump gas with STOCK Intake Manifiold, Throttle Body, Cams, and NO PnP on the head. with 6262 .63ar and the billet wheel was slightly damaged. Oh and i found out my valve lash was super tight on my exhaust cam which damaged my cam and a couple buckets..... Now my head is fixed and redone, and i also have a 6266 .82 ar. So lets see what difference ill have. Just to give u an idea.
