Having Trouble with Deciding on Which Turbo Kit to Get
Do you have any idea how much of a pain in the *** that would be? As long as the compressor inlet size was the same, and the flange was the same it wouldn't be hard to do as far as a day project, but it would be SUCH a pain in the ***.
I know that atleast for me, I have to remove my radiator to get my manifold out because of how my wastegate sits, having to remove your radiator and fans and such just to remove your turbokit sucks doing it once, I wouldnt want to be doing that **** on a friday morning for friday night drags.

which one of the kits talked about will work with my autobahn intercooler and hard pipe set:

^^^Hahaha, I know that would be the easiest haha. I decided to go with the ETS system, 58 trim, should be ordering shortly. Talked to Tom, very knowledgable and a great guy. I look forward to getting the ball rolling with the build, I'll keep everyone updated.
If your looking for a down and dirty simple setup with what appears to be the best manifold for intial spool then the BR is your choice. It should also be considered that if you never really plan to run race/meth on your potential setup that you may be hard pressed to need a tubular manifold. Also keep in mind that spoolup is greatly determined by the size of the exhaust housing. A .63 may spoolup great but will make less power up top versus a larger exhaust housing.
The FP housing is a nice setup...costs more than you think too.

If you never plan on running meth/race gas/E85, you shouldn't be considering a 35R either way- cast manifold or header.
Couple things. Our turbo kit DOES use a standard off the shelf Garrett turbo the turbine housing is the only part changed. We used the FP for spool up, ease of making the cast manifold and because it does have the port right on the turbine housing. The wastegate port on the turbine housing is one of the best places to locate it. The exception is if you have a well enough built collector with enough length to place it on the header.
AMS doesn't use a 44mm wastegate, they use a 38 mm, just to clear that up too.
I think making an issue out of needing a "custom turbine housing from FP" is silly as all you have to do is call and order it. The turbine housing is a part that shouldn't fail so there is no reason to "swap it out". You could only possibly need two anyway, a GT30 housing and a GT35r housing..........
The cast manifold does spool the turbo the fastest, part of that is also credited to the FP turbine housing.
The reason you would upgrade to the header for $800 more--->>>if you want more top end power then the header/turbine housing can provide that, the look with the header is also a reason many guys go with it.
Remember, our standard GT35R kit on my car did run 9.97 at 142.23 mph, so that cast manifold/FP turbine can certainly make the power.

i dident say that your kit did not make power. i just dont like the fact that you use mitsu flanges and not a standard t3 flange. if the wg was on the manifold and it was t3 flanges then ppl can just change and buy and standard t3/t3 turbo of their choosing and swap then out with ease. with the buschur kit you cant just go buy a standard t3 50 trim and slap it on because 1. you use miti flanges and 2 because of the custom wg location and custom turbo housing you use.
plus i dont like the fact that you cant use aftermarket thicker alumin radiators.
but the buschur is a great kit for the money and does make great power
i have the old school br500bb kit and the crappy internal wg craped out so i just welded a tial 44mm on the 2nd running and theres no boost creep at all. holds 22psi all the way to redline. full spool 22psi at 3900 rpm at 4th gear. makes 370whp at 22psi. how much boost and how much power do you think it will make on race gas? what turbo did come with the kit i have. is it a gt3076r? do you know the specs? the turbo housing says precision so is this a prescision turbo and not a garrett?

A true equal length tubular manifold with collector is superior to the cast design in question for several reasons. The inside diamater of each runner stays consistent in a tubular design because they are not subject to core shift as are the cast units. Wall thickness is also always the same so there is no variance. Tubular design separates the exhaust pulses until they meet the collector which both increases pulse velocity and creates a scavenging effect. Exhaust flowing through each individual runner creates a vacuum in the others that effectively sucks exhaust into the collector. This is obviously not possible in an unequal length cast design that doesn't capitalize on the benefits of a collector.
Spool is usually superior in a smaller turbine housing configuration on a given exducer/compressor combination. The same effect can be achieved by putting a smaller exhaust housing on any compressor/exducer package, but top end power is usually sacrificed. For driveability the goal is to select the combination that offers the largest amount of power under the curve and not necessarily which one spools fastest and tapers up top, or makes the most top end but spools slowly. By offering 15 different turbo size options in four different turbo platforms and your choice of exhaust A/R on each, we can cater the package to perform exactly as YOU prefer it for any power goal, powerband and budget. If those plans happen to change at any point later on, all of the turbos within each platform are 100% interchangeable.
