my single turbo project

[DceptvS4]

just some teaser pics. the project should be done this year funds permitting. still im excited about it and wanted to share.

[Blue_S4]

looks nice, doesnt it sit a little far foward??...what snail are you sporting?

[Go_S4]

post pics of the R33....

[AK1RA07]

Looks neat, but why did you choose to mount the turbo in that direction?

[your daddy]

your downpipe is nearly touching your fuelrail...
flip the snail around.

[laxman851]

^^^Isn't that a heat shield around the downpipe?

Why would it be benificial to turn the turbo around?... Is it to keep the heat away from the intake manifold or fuel rails?...

Also OP, if there is a reason for the hotside being towards to front care to explain?

[obviouspro]

Looks just like a fat downpipe haha. Will that downpipe be restrictive or turbulent with that immediate bend or is it big enough where that wouldn't matter? I like the location for the inlet, nice cool air in there. Will a MAF fit in there or are you goin MAFless? Also the dp does look close to the fuel line and intake manifold. Any heat issues there with the manifold Last question haha what turbo?

[Oceanside]

clever

[SlowGolf]

Please wire wheel the sch 40 bends

[mholme]

Also OP, if there is a reason for the hotside being towards to front care to explain?

Looks like because of where the turbo is located, there's no room for an exhaust channel if he had the turbo the other direction. He'd melt everything around it and he still might

[ThirdStrike]

how is this going to be safe? ?

[Trigger Happy]

Love the Pitcrew Sticker in the background. Great shop I buy all my snowboard stuff there.

This is an interesting build, the turbo seems kinda close to the fuel rails, might want to do alittle heat wraping

[Siena]

Nice job there.

Guys, as for fuel rail proximity to downpipe, it's not completed yet, I'm sure the OP knows the relationship between a red hot exhaust, and a thin-walled PTFE / steel braided fuel line.

[rstyleuk]

why is nobody attempting this kind of thing in the uk , i mean road stuff not satans ?

Siena think you should do this with the 8 that would be interesting if it would fit that is

I know exactly what you mean.

My choices for Outlaw are a single snail, or an Eaton off a Jaguar XK8/R.

They're also 4,2L V8, so will be more than man enough for the S8 motor.

[Dr.Duct]

ahhhhhh....

[DceptvS4]

The engine is still in the factory location..

Obviouspro and mholme are correct as to why I chose to have the turbo face in the opposite direction, cause theres cooler air there vice under the hood right around the block.. and something would probably melt

Yes, the DP is rediculosly close to the fuel rails because the project isnt completed yet.. I still have a few tricks up my sleeve before this project is complete.

Edit: Oh yeah.. im running a GT4094

[Dr.Duct]

ever thought about how the paint on your hood would like the hot side of the turbo and dp?

[noclutch]

Coating and heat reflective material under the hood go a long way, I've run with a exhaust Mani almost touching the hood with no ill effects.

I personally would have turned the turbo 90* and ran a 90* intake pipe back to the battery tray if you wanted that cold air. That would be much less restriction then the DP angle you have on there now with a more gentle bend for the DP.

Ya, i was gonna say that. That 90 degree bend for the DP isnt gonna help much

[XSilverJ]

For some reason I feel if the turbo was mounted sideways as in the exhaust housing was facing the drivers side that it would be way easier to route everything and for some reason just be better, no?

[GURUMAN]

Great build so far...

1-Dont be scare to push the limits.

2-Dont look at comments like to much 90 bends here and there, affect the flow and all that shit... On Az people think whe are doing rocket scinece... A 90 degree bend in a down pipe or an exhaust will affect shit in your case, YOUR TURBOED, not a F1 engine N/A that needs equal lenght everything...

3-As for fuel rail, I guess you are intelligent enough if you build this yourself to change to steel braided high temperature hose... And it wioul look a lot better at the same time...

4- Keep it up, I love it

[GURUMAN]

Look at ringlord's setup, he spool's faster than a few k04 cars...

Far from beeing equal lenght, centered and perfect balance between the banks.

[S4evr]

looks real good.

i love the idea of sticking the cold side where the battery is, it will definetly be cooler back there.

[JDM EJ1 95]

i like it... very very simple and straitfoward... dont need to go all out on it as long as it works well..


similar placement to my single setup. but a little rotated

[wdbdy2000s4]

Guru's right...don't listen to all the internet experts and e-racers...how many people on here have succesfully built a single turbo s4? yeah, exactly, not many. And how many of the people on here fully understand the physics behind building an efficient and productive turbo kit? even less. The build look sick and make sure to post a ton of pics for us.

[haus4]

Like Guru said, dont listen to everybody about having a 90 bend is the worst thing. Bends have a lot less effect on flow of air then they do for a liquid. I cant prove it, but I know that the theory is correct. Plus with such a big exhaust, your retarding factor (loss of flow) is going to be small. Once you figure out something with the fuel lines, you should be well on your way. Good work.

[noclutch]

Hey I just made a statement that I felt a 90* in the intake side is less restrictive then the crazy bends in the DP; Being that the cold air is the reason he gave for the turbos position. It just seems like turning the turbo 90* would make DP fabrication easier and less restrictive and charge piping a little more direct.

I think its a great looking project personally.

[AK1RA07]

Is there any room for a filter or inlet pipe of any kind the way you have it situated or are you just going to leave it open?

[rayveedub]

i wanted to clear up a few things and thank everyone for the enthusiasm. we are even more excited about the project!

1. the system is far from finished. we are making the entire fuel delivery system including the rail. that is only there for mock up. also we are making a entire new cooling system.

2. the turbo is a gt 4094

3. the location of the turbo is the only place we found the keep manifold travel to a minimum. the turbo is twin scroll and has a bank feeding each side of the scroll. the tight radius bend in the dp is not a problem for flow, also with this setup we can do a pipe that goes straight up and out through the hood of the car ;). the turbo itself is the biggest exhaust flow impeadment. also it was important to put the turbine section in front of the firewall. the plenem cover still fits onto the car covering the compressor housing. looks crazy with that on lol. the log portion of the manifold (3 piece manifold vband flanged) is sized 1.25 inch at the front 2 ports than upsizes to 1.5 inch at the 3rd port and continues to turbine this size.

4. we are going to be running standalone management. no maf. air filter fits.

5. no expense was spared when it comes to heat containment. everything will be ceramic coated minus the turbine housing. that will be in the bag. we will still thermal wrap everything as well.

all in all this is a amazing project. i cant wait to get it started up.

[Reich]

Exhaust is also close to coolant outlet pipes coming from heads, but you know what your doing.
I like that kind of project. That's amazing.
Please keep us updated.

There's no recession where you live right?

[ENDEE666]

I would love to see more about Ringlord's setup with the turbo where the airbox used to be... Any threads on that? Couldn't find by his name...

The thing is it's a Audi coupe 1991 with a swapped 2.7 single gt35R

The frame rails are a bit wider in the front compared to a B5.

Maf goes down between inner fender and front bumber.


I'll try to fin a picture of that tomorow in his computer...

[Siena]

^^^ I guessed it was a B3-based car, was looking at the top of the fenders, and the right-hand hood catch, with metal front panel.

Subframe was a clincher too.

Good work!

Looks like you know your euro cars

Ah, didn't look that close to catch those things. Was distracted by the 35R on the 2.7... But that in a 91 coupe sounds SICK! Why not just have built the 5 cyl or swap urS4 motor tho? Aren't those things insanely capable?

[lucajS4]

im gonna kill someone i cant wait to start mine !!!!!!!!!!!!

[DceptvS4]

Just an update for everyone whos been following my build.. Rods and valvetrain are on the way, FMIC is here, were still discussing which injectors we want to run.. once we get the motor built, we'll hopefully be starting on fab by the middle of next month

Just to answer this question... yes, they are VERY capable. I would've done exactly that (swap a Turbo I5 in) instead of the 2.7T. They are very very strong motors and cheaper to get high horsepower out of. Also sound better than our 2.7s, IMHO.

[I know I know, blasphemy! ]
