What you guys think about that? Its much easier build turbo setup on exhaust than under the hood. Even turbo kit sellers sells those kits.

But Squires doesn't sell a pre-made kit for a 3rd gen. You might as well piece that style kit yourself & not pay the extra for the Squires name by buying the Universal kit.

Considering the lack of ground clearance under a 3rd gen? A rear mounted turbo system is difficult just like running a true dual exhaust because you hafta run an exhaust pipe to the back & then a charge pipe back up to the front. Been talked about & some tried, but I have to see one successfully finished.

 

Yeah i just showed link i dont wanna buy there. Its pretty simple and cheaper do build own kit.

 

A remote turbo would be easy to build on a thirdgen. The only problem is you would need a scavenger oil pump. These cost a good amount of cash for a good one. Getting oil to and from the turbo wouldnt be too too hard just costly for the pump and if you didnt get it set up right the turbo would fry in no time.

RMT is a good idea though and if you search arround a bit im sure youll find some more threads on it. I know Ive ran accross a few threads as at one point I was looking at doing that insted of the set up I ended up making.

Haisud you have a V6 correct?? If you do endtertain a front mount Turbo, it is very easy to fit in the engine bay. We as V6 owners have the perfect amount of Area to add a turbo.

 

First, I'll admit that a front-mount turbo system would be better in numerous ways.

About the only way the remote-mount turbo system would make sense is it has the least amount of fabrication work and it gives you the sleeper look.

If you wanted to do the remote-mount turbo set-up, I'd recommend...

Ceramic coat, heat-wrap, and do the over heat-wrap paint on these:

Cut this where you intend to place the turbo, weld on the turbo flange, ceramic coat, heat-wrap, and do the heat-wrap paint on this:

And, I'd pick your turbo from this page:

You'll probably want to go with this one:
http://www.turbochargers.com/estore/...-a-r-2-8l-3-2l

Those are the actual STS turbo's that they offer in their kits. I recommend their turbo's because the have the T04B compressor, which is best designed for high volume of air-flow at low pressures. That's the kind of system you'll be running. It's very hard to find an eBay turbo that has a T04B compressor on such a small A/R turbine housing.

You may ask why I suggest all the ceramic coat, heat-wrap, and over heat-wrap paint. Well, your spool-up is now dictated by exhaust gas heat and velocity. Heat and velocity are mutual in this application. Front-mount turbo set-ups don't send their exhaust gas through all the length of exhaust pipe that a remote-mount set-up does. The exhaust gas needs to be kept as hot as possible to help with spool-up times.

You'll still need the oil-scavenge pump that fasteddi mentioned, oil-line, waste-gate, and blow-off valve. And, I'd be shocked if you hit 300WHP with this set-up on a 2.8L V6.

 

I was considering remote mounting my twins but simply no room to adequately fit all the exhaust piping. The cold side i debated about running thru the interior but passed on that idea. A single rear kit would be alot easier a you can run dual pipes down the stock exhaust route location. Depending on motor you can run 2.5-3" exhaust feed and have a 2.5"-3" return cold side. That would work well and have great ground clearance. It would get alittle tight up in front of the car where the ypipe would be but that depends on where you place the merge and crossover.

I have front mounted turbos but use the scavenge pump for oil return. It works great. Wired into fuel pump relay so when car runs the pump runs

 

theres actually a 66mm ebay turbo with a very small t3 turbine with .48 housing on it

 

Now that rear mounts have grown in popularity and all kinds of pumps have been tried on this and that. What is the best bang for the buck? Is the cheap questionable Shur-Flo still a good option or is there a cheap pump that withstands heat better?

 

For a RMT.....Wouldn't an independent oil reservoir & pump be a good thing? Oil reservoir in the back & an electric pump circulating the oil to the turbos & back to the reservoir.....It's own oil supply.

 

That would be a good idea as long as you keep oil cool and pressurized. May need a supply pump and return pump as well since i doubt the reservoir will be lower than turbo back there. That could get pricey.

As far as pumps i do not know whats cheap and works. I took no chances and went with turbowerx exa pump for 400. Its suppose to be the pump of choice for remote apps or low mount turbos where gravity drain is not possible. They have a smaller version thats 200-300 but not sure if its built as tough and not sure its capacity is enough for twins.

 

If you ignore the thermal dissipation problems then yes.

 

It looks like the Mocal is still a popular choice. With the engine you built I would have also gone for the best pump I could find. As for the capacity, you can calculate it.
Holset likes to see about 3 liter/min above peak torque. This is about .8 gal/min. The Mocal fits well. What is the GPM of the two turbowerx pumps?

 

I have only 1 of those pumps and its suppose to be 2-3 gpm rate of scavenge. I tee'd my drains together and single outlet to oil pan. Pump has 10,000 hr rating and 350 deg f limit. No idea what my oil drain temps are i have yet to measure. I gotta put the oil cooler in eventually.

 

Im still questioning if he has a V6 car or not. Because for some reason I thought he did. The front turbo would be easier and cheeper to toss on. Hell#, we have like 2 ft of room in the front of our motors since there so dinky. Twin turbos would probly be just as easy if thats what you wanted also, just sizing them up would be very important. But if he has a V8 car its a different story in how much room you have to play and fabricate with.

Look at all that room



Just saying.

 

Care to elaborate on that statement?

 

I think it would be a good idea. If the res. was made for heat and a good size, the pump made for heat, and you would need some sort of heat exchanger to keep the temps down so that it doesnt turn into sludge. I know the turbo has to get that oil cooking exspecially if its a sealed system outside of the engine where it would actually cool down. All that = $$ that could be spent else where in my opinion.

Thats just my idea on the comment, Im a newbee so don't take what I said as a good comment. Its just a thought and knowing my luck is wrong...lmao.

 

Thats correct. The oil will get very hot after a little while of driving. Track car it would be fine...actually would need to heat the oil to proper temp just like the motor oil to achieve best lubricating properties but most oils are ok at all temps so the turbos shouldnt care.

For street that sees alot of driving, you'd want an exchanger with fan. Thats alot of stuff to mount back there but can be done. The exhaust gets hot enough back there to melt plastic gas tanks so a turbo is only going to make it worse. So the oil running through all that is going to absorb the heat and could eventually break down.

 

i just swapped low mileage 3.4 v6 in it. I want build turbo, but i scare ecu programming and i dont wanna let someone program and take money for it, is there any video or something how program stand alone ecus like megasquart, vems or something?

 

Dont be scard of the ecm tuning. You options are to either stay with the stock ecm or go to a stand alone such as the MS. I have no advice for the MS or other ecms like that as I have reused the stock ecm in my case. I run $59 and use moates equiptment.

Front mount is my best opinion on a V6 car just becasue of the room up there to add compontets. The low cost is there also even if you dumb good high qualitly parts up there. Mainly because all the oiling system on a RMT can add up if you get the good stuff.

Tune it yourself in my opinion also as paying someone to tune it will cost a good amount of $$ if you can find a local place to do it.

 

What is $59 and will it work with 3.4 ? Will it work with original wiring harness or need mod?

 

Not sure if it would work with a 3.4L ecm. Im not even sure what ecm is in those models. Someone Im sure does know if it will or not. Orr89. Sixshooter are a few that use $59 they know alot more them me as for a application.

Megasquirt is a good option too. Somewhat inexspencive and can be installed by a begginer.

 

My 2.8 ecu works with 3.4. I must buy 7730 ecu and then i can use $59 ?

 

I use a 7730 ecm to run $59 and I believe that you would need that or a underhood verson, 747 IIRC. (once again its early in the morn and I may have the underhood ecm number wrong) Im sure you may be able to use others but I used the 7730 ecm and basically didnt have to change anything on the pin out(harness) to make it work. $59 is speed density apposed to the MAF that you have on a 2.8L and let alone the 7730 is a much better ecm then your 2.8L counterpart.

 

the 2.8 ecm can handle 7-12 psi without any ecm tunning needed ( it depends on the size turbo u use)

if u use the smaller 48mm ebay turbo u can run about 12 psi
if u use the larger 57mm unit like fasteddi is using the stock ecm can handle about 7 psi
u would have to swap in some 350 tpi injectors, the car will run slightly rich at idle and part throttle but be 12.0 afr under boost

member blc85 i think is his full user name has done some work with the 2.8 ecm and boost and has his own code to allow alot more boost, it also allows the 2.8 ecm much better control under boost.

u could pm him he may be willing to share his code and or burn u a new chip for the 2.8 ecm , i belive that was his intentions when he started the project


using the stock 2.8 ecm would be the easiest way to go about it until u get comfortable with an ecm swap to the 7730 and code 59

while the 2.8 ecm will work it took me 18 psi of boost on the stock ecm with an fmu to run high 12's, i later swaped to a megasquirt ecm and went low 12's with only 9 psi.
using the stock 2.8 ecm will leave alot fo power on the table unless u actually burn new tunes/chips for it

the 7730 is a much better ecm once u get ur feet wet, and even easier solution would be a megasquirt 1 system which is what i ran on my car, the ms1 system is 311$'s for everything u need, not sure how much it would cost u to swap in a 7730 and get all the tunning equip it may be more or les then the ms system. sixshoter and fasteddi can help u get that sorted out, as i belive u will have to replace the 2.8 harness with one out of a 3.1 for the 7730 to work, but im not 100% sure on that
