STS Rear-mount Turbo

[zbouncer]

Did a couple of searches for a rear-mount turbo on a Yaris and so far it looks as if it has never been done before, nobody thought it was interesting or nobody thought of it :iono:

Here is the link http://www.ststurbo.com/universal_turbo_systems

Lets discuss some pros and cons :hitcomputer:

Looks like this application is for larger cars and trucks, looking at the website.

I think it's more piping (= more lag on our cars), custom set up (just as much or more work than a front mount), can't think of any pros except "cool factor".

[zbouncer]

Yeah they get great results on LSX cars/trucks...just thought I would throw it out there...it didnt really say the size of pipping it comes with. I know this system is made to bolt up to stock f-body pipping (which cant be more than 2" from the factory), and the exhaust gases and intake air wouldn't have to travel as far on a Yaris LB as opposed to those other boats?
And yeah they sound freakn sweet back there ;)

if you want to be unique you should buy the new microimage hood and do a top-mount intercooler

I have seen a rear-mount turbo on an integra before and Super Sport has a Lexus IS-F with dual rear turbos in it this month.

I think that its a cool idea that you see pop up every now and then (never seen the idea mentioned on YW before though). Do it.

buddy in jersey had one on his camaro. it wasnt too bad, and lag wasnt any more noticeable than a normal turbo setup. it's a good idea, removing heat and space taking stuff from the engine bay and moving it to the back of the car...bmw and mercedes have been doing this for years with batteries, why not turbos? the piping acts as an intercooler (although not a good one) and you can use any size turbo/piping you want (depending on spacing available). the real problem i see is that it's on the rear of the car, unprotected from all the thieves out there. it's so far back, and just under the bumper...very easy access specially if you back into parking spots.

other than that, go for it. you wont need a muffler, and all you'd rally need is a metal intake plenum or manifold.

[Cosmonaut]

lol. cool factor is about it. more tubing=more money. and im sure heat loss will degrade the maximum efficiency of the turbo...unless you will be using some kind of thermal barrier. plus the intake side would most likely become an interheater rather than an intercooler.

[justjesus]

STS has been doing it for years....with great success. They did their homework and made it work. Surely they might be able to make some suggestions for a smaller displacement engine. Just call and ask ;)

[cali yaris]

ok, pros and cons have been discussed.

zbouncer, you going to do it?

[severous01]

if i had the money i'd do it....

money and a metal intake manifold!

interesting... i've seen this company years ago. its geared more for american cars/drag cars but there are a few clips around youtube of some imports fitted with STS. It doesn't seem like it comes with any computer controlled ecu or piggyback unit nor did they offer bigger injectors and all the little things people tend to overlook with power adders. Im guessing they are banking on the customer knowing this and supplying parts themselves. Or using that electric boost controller and low boost to save the motor.

the universal kits dont come with anything but a turbo setup. which is good for someone who knows what they need and can get it...but bad for someone just wanting to throw it on n be done w it.

the specific kits come with injectors, programming options, setup options, turbo options, all sorts of options. even dual stage electronic wastegates. my friend's camaro has the dual stage w/g. he runs 13 on street and about 20 on the track with track gas.

where's the OP

Here you go rear mount turbo festiva

[cdydjded]

Rear mounted turbos dont work, see the vid below:

8.87 @ 155, that thing is sooo slow (Im being sarcastic)

Funny how new ideas get shot down by people with no experience using them. I wonder if Thomas Edison would have listen to the neigh sayers what we would be using to light up the night...

^ why did you design a front mount turbo for your car?

[severous01]

hey, any news on that metal intake manifold that was supposed to come out in december???

[cali yaris]

Yeah -- it didn't. However, I did get the finalized drawings, so it's off to a new fabricator.

1 Cost

2 I have not been able to find the oil pump system that STS uses

3 I live in Miami, when it rains is floods here

[severous01]

you just tap into the main feed line, or into the side of the block where the test spot is. the pressure will be enough to send it to turbo and back to sump/pan.

cost i can see, and i can't...a custom manifold could cost upwards of 1500 bux. the whole turbo setup for rear mount could cost 1500 bux. but, mounting, welding, rigging and setting up could be a pain if you dont know what you're doing. plus there's much more room in the exhaust/rear section of the car over the engine bay.

and i can completely understand the water...i live in SETX...when it rains it floods...and it rains often. i actually had to shield the top side of my intake where the hood stops and the bumper starts....water was poring in there.

any way, when i start getting funds together and whenever a program setup becomes available...i may end up with a rear mount setup. seems to work good on v8 cars, sold on me.

[cdydjded]

Sorry but the pressure is not enough to send the oil back. That is why STS has an electric oil pump. Oil is high pressure in and gravity fed out. Go ahead and get the STS kit for your car. They sell a universal kit that should work.

[Nexus1155]

my buddy from turbowerx makes a great electronic oil pump that would work great for a rear mount turbo, I can see the use for a rear mount turbo in a car that doesn't have turbo kits readily available or in an accesible location, but not really the yaris. But props to you if anyone tries it.

[sleey0]

I'd buy one right now if I knew how to install it :P

[zbouncer]

Yes it will require a electric oil pump/sending unit and it also has a low pressure alarm to let you know before you kill the bearing on your turbo. Cost is an issue, not really the money just the fact that it would cost me about half of what the car cost to do the mod and not really wanting to do that on my DD. Just thought it would be a cool topic since nobody has brought it up on here before. Another advantage would be weight distribution to the back as apposed to the front and might even be lighter than stock muffler?
Anyways it sure would be sweet to see someone put this on their Y :burnrubber:

[zachryboles]

if i get this new position at work im considering piloting the first rear turbo yaris......... lolz for pay bumps
