ok here's what I want to do. I want to take a stock sr manifold and either make a t2 ---> DSM flange adapter or take a megan or similar bottom mount stainless steel manifold and cut the t2 flange off and replace it with a dsm 4 bolt turbo inlet flange. Both of these mods seem like they work on a bottom mount sr to enable mounting of a Forced Performance turbo such as the fp 3052 (which is better than a 3076 but supposedly around the same size and comes with a roughly .68 exhaust housing). I'm guessing if this one fit the fp3065 would also. The reason why I want to incorporate this turbo into my setup is the use of vband for the 44mm wastegate which is actually on the turbo housing itself along with a vband exhaust outlet. I believe this setup on a sr would be great and save weight along with allowing easy modification of a aftermarket t25/28 turbo outlet to adapt to the vband. Imagine one bolt to unhook your exhaust and your wastegate...along with having the performance benefits of being externally gated kind of lmfao...but still remaining bottom mount without having to pay crazy amounts of money for a topmount to do the same thing. Granted I know most of the topmounts out there use longtube design...so I'm not talking about the exhaust flow performance aspect. Basically I'm wanting to put this on my fully built blacktop...and I'll be able to buy a badass fp3052 for the amount of money I would spend on a ATP3076wg. and have it's advantages of course. Anyway if anyone has any input on this please share. I'm looking for advice and opinions on whether or not clearance would be an issue in your thoughts...and also from anyone who would have the means of mocking an adapter up to share with the community. I really thing someone should make an "FP like housing" but with a t2 flange and a vband wg flange along with a vband dp flange....imagine the sales of that item!

OH HERE ARE SOME PICS OF THE SETUP OF THE TURBO

or here's an idea too...I found this on grenade's website....again...this sucks that I have to look for this stuff that much to find it. Shoot sr's are so prevalent now you think the r n d would be insane and the turbo outlet shown here would've already been in mass production.

2 things i'd like to put on the table for you:1) i believe i heard something about the DSM turbos spinning the wrong way, or maybe it was that the inlet for the turbine was on the "wrong side" if you get what i mean, so that it wouldn't fit almost at all for us RWD SR folk. i have no interest in this as i know exactly what i want, but i thought this was why we can't use the very nice EVO3 and EVO8 16G turbos.2) having the outlet to the WG on the turbine housing seems like a bad idea to me; it will cause turbulence, of course, and i would want my turbulence a bit farther away from the turbine itself. i do like how the neck for the WG is perpendicular to flow. i can see this helping keep the wastegate shut longer thanks to the Venturi effect accross it. but i'd want it farther from my turbine wheel, that's all.

where do you think an internal actuator is? it opens and closes just as this one would...turbulence would not be an issue. And as far as the turbo mounting up wrong...I have no clue where you're coming from on that one. Then technically dsm users wouldn't be able to use gt variants such as 2871r, 3071, 3076, 30r...when we can use those bottom mount too just in a t2 flange..or a custom such as full race. Mainly I posted this looking for people that might know of someone thinking along the same lines as me or might know someone making a manifold that would use this. I'm either getting a used hks 3037 in the future, going with screamer pipe external wg modification or trying out this idea. Basically I know it would work ...it's very simple. As soon as I sell some more stuff I'm going to work with a guy who does welding for Oak Ridge Labs in building a long tube bottom mount manifold...I won't run into clearance issues ...so I can go crazy with length....did you ever see the blue SPEC car that was at some of the Formula D events? I've kinda been wondering though when length outweighs performance on runner length (especially in the case of remote mount turbo systems) I'm guessing as long as the runners are long it's fine..but when the charge pipe becomes lengthy you lose that benefit...I dunno someone elaborate on this.

to some extent longer runners will slow transient response a bit, like larger/longer charge pipes do. so i guess it comes down to what you're trying to do. although if it's designed well this shouldn't be much of an issue as the efficiency of flow should come close to outweighing or even surpass this effect. for sure it's an issue, but you may gain so much from a good design that it's not noticeable.
