Just wondering if anyone has looked at remote turbo style system for a twincharge seyup??

they are not as laggy as people think if you select the trubo corectly. also if you wrap the whole exhaust system spool is pretty similar to front mount systems. it would also be easier to install than a normal turbo system.

anyway here is a company called STS that sell rearmount systems. http://www.ststurbo.com/home

what you guys think??

Chris.

 

Where would the pipes run on the MINI? Not much space in our cars. The cars featured on that site are all corvettes, mustangs and big trucks. If it could fit, I don't see why it wouldn't work any less than a normal mounting spot. They don't seem to complain about boost drop, but the system must add some weight.

 

I do not think that this would be worth the time and money involved...

 

nabeshin, you are right on the piping, it would be tight, but there is allways a way. also you wouldn't want large bore exhaust pipe work as this causes some additional lag. so maybe 2.5inch exhaust and intake piping going back to a turbo at the back.

i dont see how this kind of system would add any more weight than a conventional turbo system. infact *** you are loosing a back box then there the weight would be about the same. the only additional weight would be from the oil pump.

ChrisMCS04, could you exspand on this some more?? what problems do you forsee with such a kit?

anyone else got any coments??

Cheers, Chris.

 

this is how it has been done on an old school mini.

The peripheral parts and etc...needed other than regular turbo systems would be a PITA. Too much fully custom parts = $$$$$$$$ out the ___!

 

I put the STS setup on our 2002 Yukon Denali. GT-67 Turbo with a 5psi setting and a 9psi setting. The 9psi setting was set to run Methanol Injection. It put down around 260awhp stock and 472awhp on 9psi. That's with 523lb/ft at the wheels!

They now sell "universal" setups. Could be a fun project!

 

thats what i mean. lots of guys are running these style system and making good power!

i will have to see what turbo they supply on the universal kits. a kit could be built using a dencent oil pump (these are not just used for remote turbo kits but also low mounted turbos and they do work!), turbo, waestgate, back section piping (retain stock exhaust), boost pipe form turbo to intake, air cleaner, etc.

should be easier to fit than a normal turbo and basically a 'bolt-on' mod.

Cheers Chris.

 

the mechanics of forced induction are easy. it's the tuning that always gets you.

 

ok how about this....

remove the back box that is normally ditched in a one ball mod. then run the piping around and into the turbo (turbo facing backwards and mounted towards the centre of the car). the air cleaner for the turbo would be on a 90 degree bend running along the rear bumper with a sheild to stop road crap getting to it. the exhaust form the turbo could then run long the normal route either into the remaining back box, or into a race can, or even just dump depending how loud you wanted it. the cold piping would have to be mounted near the exhaust route, but i dont think anything more than 2 inch would be needed. the wastegate is a little tricky. could poss run an internal gate. or maybe have an external gate mounted on the other side to the trubo.

the intake pipe would then have to come up to the throttle body.

thanks Chris.

 

When do you want to book it in Chris?

 

I really don't understand the point of considering this. We already have available several twincharge kits.

Why is there any attempt to re-engineer already available designs? Is this company providing something we don't have available already? Maybe I missed something.

when i can get the about 20K needed to get it mate! girlfriend just had a baby so money is a bit tight at the mo. just knocking things out in my head.

Chris.

 

Matt you have a god point, but there is NO 'bolt on' twincharged kits out there! the Alta isn't a true bolt on and has not proven to be reliable (cracked manifolds). just trying to think outside the box and throw some ideas out there.

the main advantages to remote turbos are:

no increase in under hood temps thanks red hot turbos and manifolds
simple bolt on system using stock exhaust mounting points etc
simple instalation
ratian stock look under hood
reduced temps entering SC (try getting that on a front mount)

the diosadvantages to a remote mount over a front mount are:

No under hood bling that a trubo gives
reduced spool up time/lag (this can be worked out with proper turbo selection and wrapping the exhaust)
a reduced ground clearance (no a problem if you can get everything mounted high enough)

i know there are going to be people that say 'thats a stupid idea there is already stuff that can do it' and i understand that statment. however there is never one way to do something and often the alternative ways have their advantages to!

thanks for the points though.

 

read this old thread for a better understanding

https://www.northamericanmotoring.co...ght=rear+turbo

 

STS does the rear mount turbo's for vehicles that dont have space available in the engine bay. You can about a 3-4 psi decreace in boost pressure by relocating them all the way back there. We have room so why even do this?

 

They want $2995.00 for the universal kit I built a homemade kit for my civic and it cost me less than 1200.00, including the tune. I bet building one of these remote kits piece by piece would be easier and cheaper to do, if you know what you are doing. Turbo 250(ebay), steel braided line 100, piping(nothing fancy)300, flanges( wastegate,bbv,)300, Injectors and tune 900 but these two things you need with the universal kit anyway. total 1850.00

 

It'll sound really cool to have that turbo spool sound in the exhaust!

 

We spent a couple of days two years ago looking into this type of application. There were several pluses , low under hood temps , superior cooling of the exhaust entering the turbo do to the long path etc. The real sticking point is of course space . The turbo itself was not a problem as we were going to fit it in where the drivers side rear resonator USED to be The real tough part was the running of a return pipe back to the engine compartment. The tunnel which the exhaust pipe currently resides in is the logical choice but once you start with a dummy mockup you realize just how tight it really is. You would have to run two smaller than optimum pipes and even then the minimal space between the two would be hard to guarantee no vibration issues between the them. Another sticking point would be the running of the oil cooling lines to and from the turbo for cooling purposes. I'm not saying it can't be done I am just saying we spent some time looking into it seriously and realized it was something we did not want to pursue. Your results may vary

Oil lines would require some thought as of how to get the oil back to the engine. Gravity would not be your friend here, so you would need to engineer in a pusher pump of sorts. Coolant should u choose a turbo that uses coolant would probably be ok w/o a pump. Plumbing in the pressured airline would prove to be a challange like Randy said, there isnt that much room in that channel however you could route it back under the car if you used 2" or 1.5" piping.....Turbo selection would be crutial to get the most out of the setup...the SC will help spool the turbo so you could get away with a larger turbo....

 

you are very right mate!

oil return would need to be by (the tried and tested in applications other than remote mounts to!!) an pump and could either be plumbed into the sump (requier taking the sump off like in front mount turbo instals) or into the head!

the boost pipe from the turbo wouldn't need to be more than 2inch. not sure of the room but could even used a flattened 3inch pipe down to say 1.5inch if needed. should give the same flow but more clearance. dont know if a 2inch reucetion in clearance would be a big problem anyway.

turbo seclection would be very important but i think a GT25 hotside might spool fast enough. there are a million and 1 possiable turbos that could be fitted. also lto minimise lag you would need to wrap the exhaust to help keep the heat in. if you silicon coat the wrap it can be very tough!

cheers Chris.

 

got any more info on the turbo you used?? thinking a 2.0ltr civic would spool about the same as a 1.6 MCS.

thanks Chris.

 

I had t25 setup on my dx civic that put down 201hp and 186tq to the wheels on stock everything. At 3500rpm i reached full boost at 14psi. The charged pipes i bought off ebay for $80 and cut them as needed. The couplers provided with the kit held them together without ever popping off. I could have gone with a bigger turbo for more top end, but i like how a smaller turbo launches off the line. If you want top end T3/T4 would be better because it needs more exhaust gas to get the turbine spinning.

 

After reading about the remote turbo setup, i think i want to give it a shot, instead of installing head.

 

hmmmm maybe a Gt25/28 hybrid might work???

maxmini is ther eany other reasons why you chose not to take the kit any further?? it works great for the V8 buys so why wont it work on a smaller scale for the MCS???
