Top mount turbo setups

[essejkcamraw]

I WANT!!

[spnkr21]

Mark that setup is so sick. Love the fact that it's twin-scroll. Too bad it's not running

Dj you're def doing the right thing with the top mount option. If I could do it again I would do the same. The fact that mine is vband right after the collector makes it a lot easier to work with. I wonder if you could do the runners to the side like mine and then vband at the collector. That would allow you to run a single tube after the v-band and place the turbo wherever you wanted. Just some thoughts.

and how much will it cost?

We need a section where you have to be invited to be able to post so threads like this can only get help from people who the help is wanted from

May sound harsh but it gets tiring catering to people who ask questions about things they will never even ponder doing.

Anyway Dustin - Marks manifold is a great start. You'll have a little more flexibility as his turbo flange is larger as well as the space the turbo takes up. Running a smaller frame will make it slightly easier for you. Good news though - you're about to get A LOT of practice!!

A good idea could be to do it similar to the DCR you have. Build a manifold that sits lower for a top mount and then a modular pipe to the turbo so you can rotate and adjust it to fit best without having to do redesigns from the collector back instead of just hte collector forward!

@ the shop I was just at i saw a guy who had a gto w his turbos under the car in the back.....kinda where the mufflers would be sorta. i guess. he said theres no more or less leg bc its all st8 piping to and from. i asked why it was back there he said bc they didnt fit upfront w his new engine and it is much cooler there so they will work better and last longer.

Mark....... fycn. Srsly. I love your fucking setup.



I'm definitely liking the idea of top mount with v-band modular section from collector to turbo. I think this is gonna be pretty simple honestly.

SPD Exhaust has some pre-fabbed collectors that look pretty damn nice, and would save me the trouble of screwing up the most difficult part of the fabbing.
Merge Collectors

They have a v-band option and a turbo flange option, and you can specify everything down to the angles of the merge etc.


fuck i want my spare block already so i can start mocking this up... :-/

I'm gonna get the head flange made next week maybe.

how can you brace a top mount manifold or support the turbo so you won't have to reweld it all the time?

Look at the lower left hand corner of the turbo flange:





It's as simple as that. If i go v-band at the collector, i'll have to brace from that point, but i think it would be more than fine. I really like the modular approach, in case i ever end up going t-4 or something.. (i know it sounds stupid now, but i like planning for the future lol).

Bracing is gonna be important.

who me?

the guy with a 98rs wiseco stroker EJ22t DOHC hybrid setup or wait maybe my 95 S14 SR20det...
I may have only 5 post but dont make the mistake of assuming things your not sure of, its an honest mistake though dont worry its ok


and I know what you mean about the bubbly sound thats the whole reason I originaly went borla with my subie instead of the equal length setup TWE has, I'll sacrafice a few ponies to get a better "quality" sound

go v-band an never look back. it will make everything so much more simple.

[djuosnteisn]

This is quickly moving up on the list of things to do...

[xcoldricex]

yes v-band! get a tial .82 exhaust housing!!!

[djuosnteisn]

I've seen those, look decent, but i like the wider selection of the t3 for now. We'll see what i end up with lol.

[djuosnteisn]

Okay, on the topic of bracing, i think this is the best way to do it.





Looking at both SS's and Mark's manifolds, the turbine flange is pretty close to the head flange, so i'm thinking of just making it one piece. And as long as it's placed right (or close enough, cause it looks like there is a gob of room), it'll serve as the jig for my pipe routing.

I can also add a wedge like i colored in the side shot in red. That'll help tremendously for support.


Now i need to think on the ewg setup. I don't want it to be under neath the mani cause it'll be hard to swap springs. So i'm thinking since i want unequal length runner intentionally, i'll just route them such that i can tuck the ewg up between two of them.

More MS Paint to come lol.

[xcoldricex]

mspaint > solidworks.

[djuosnteisn]

Not sure how feasible it is, but from looking at mark's pic's i think i can squeeze the EWG runner up under the down pipe, and then just recirc it back to the down pipe.

That's a band-aid ninja, no matter what you say...

[gsrtype1]

As I was tellin Justin my buddy that came out for a tune last week has a top mount t3/t4 50trim setup I should have taken pics. Im sure pics and info on his setup will surface here soon.

[turd burglar]

hey dustin i know you're not the biggest fan of ptp but call john he'll sell you a head flange for 50 bucks. at least last time i asked john he said 50

[djuosnteisn]

LOL, i'm pretty sure john hates my guts. Understandably so, but still.

I'll just get one made locally. My buddy (mfquint) has a spare pg mani i can use for a template. Can't really use the factory mani cause it's a two piece.

[kore2000]

Stole these from my original thread.

Don't know how much help they might be but here you go

[xcoldricex]

lol flex not bandaid

I'm just saying

[xcoldricex]

don't get too excited kore2000

recirc to down pipe? dump that shit son!

[xcoldricex]

meh, i'm going to recirc too, not a fan of dumped ewg. rather hear the turbo and bov

[hnda etr]

Is it just me, or does that first runner on the right (#1 I believe) in pic 3, look smaller than the others...?

[turd burglar]

fymn (fuck yo manifold ninja)

[kore2000]

It does but it's just the pic. I've looked at the runner quite extensively and it is the exact same tubing and the exact same size. I think it is just how they did it.

[djuosnteisn]

i think the pics were taken with a wide angle lens.



some real sexy mani's in here... (full homo)

[spnkr21]

Fuck yea. ^^^^

[SneakyP86]

DJ if you want some help of what it might look like from the backside of the motor here is a link to my thread from when I mocked up my setup on a spare block I had.

http://www.mazdaspeedforum.org/forum/foru...rk-road-50510/

and a couple of it mounted in a MS6 in blow through.







anyone interested that whole setup may be for sale, as I think its gonna be MS6 DD and Miata Project car.

[xcoldricex]

that wiring is a hot mess.

[SneakyP86]

That wasn't on my car, thats on the car the manifold was made for. Also that was when they first got it running my understanding is they got it prettied up later on.

[xcoldricex]

does the blow through maf fry maf sensors faster?

[djuosnteisn]

I can't wait til the day comes when all these fucking cars are finished and up n running.


so much power in the near future.

[NJSPEED3]

now i dont even wana post up pics of my mani thanks!

looks like a neat idea, but good luck gettin all 10 nuts tight on the head ese!

[djuosnteisn]

I was thinking of making it with windows on the turbo flange section, so you can easily get in there. I think it would only need one "window" honestly.

Kinda like this.




We'll see how it looks when i get my motor to use as a jig. And even with a window, it'd provide a gob of bracing.

[kore2000]

DJ, don't forget about the brake reservoir. I know when they did my mani, they had to do a really hard turn on the intake because of it. Mark's was done much better in that aspect, but if I had to do over again, I'd probably ask them to crook it a little sideways so that the transition was much smoother. I still may ask them to reduce my intake to 3.5 and redo it cause I really hate the hard transition.
