thinking of turbocharging

[SHOCarGo]

i was thinking for turbocharging my SHO but i was wondering about putting the turbo in the back under the car so at first look under the hood no one will think about it..

but whats the pro's and cons of doing this

the the reason i would post this question, is my wife told me to get a list of pros and cons. for the project because a lot of our money would be used for this project.

the only thing i can come out with is "Pro" makes it faster

search the forum for remote turbo. I guarantee you'll learn some stuff.

In my opinion putting the turbo in the rear is much more efficient and better in most ways. No custom header or Y pipe necessary which is usually the biggest hurdle in turbocharging these cars.

As far as Pros and Cons do some research on STS Turbos, especially their website.

Make sure your fuel system is upgraded adequately for the boost: higher flowing fuel pump ($100), bigger fuel injectors ($250-$350ish), and an aftermarket fuel pressure regulator is HIGHLY recommended (shonutperformance.com, $230)

You will need a way to tune the car (TwEECer tuner highly recommended $350-$500ish)...this will help the computer account for the needed larger MAF sensor and larger injectors, PLUS much more...

Choose your turbo wisely, do some research on this...search the forum for turbo builds and get a feel for what kind of turbos others have used....T3/T4 hybrid sized...appropriate flanges and plan a proper oil system (search or a Tilton pump)...

Make sure everything else on the car is up to par (clutch...upgrade recommended)...transmission (limited slip differential HIGHLY recommended $1500~.....be prepared to shorten the life of the trans/gears when you get above the 300-330TQ range)....good suspension and BRAKES should also be planned if not already in place!

Very well put. Since this is specifically related remote turbo setups, think about this:

All you need is a well sealed exhaust to get the turbo spinning. That's a whole heck of a lot easier when you don't need to build custom exhaust from the manifold back (as stated above, but worth repeating). You can route the return piping as simply (Don't diesel rigs use 3"+ flexible stainless?), or as stealthily as you want.

I've seen this setup in a recent thread, Yep, here it is.. A lot of the benefits are discussed.

the benefits of a turbo kit(especially remote-turbo-goodness) are this:
fuel economy can increase(when not on it all the time)
merging is easier
onramps are more fun
highways are more fun
the looks you will get are priceless
and its actually fairly cheap to do a low boost setup with a remote style.

Now on to that last comment... Cheap is a relative term when you talk about turbocharging a vehicle. The thing is, that I could complertely copy my entire setup with pretty much everything you would need to do it, minus the tranny or motor being built(fuel system, tuner, exhaust work, piping, hoses, turbo, bov, intercooler and maf) for less than $2,000. With enough extensive searching, I could probably do it for less than 1,500. with enough searching, things can be found used for fairly cheap.

here is my parts/price list

tweecer R/T 400 (used)

turbo 150(used)

fuel pump and injectors 175(used)

intercooler 120 (new)

miscellaneous piping(intake and exhaust), 175(ebay, junkyards, wherever i could find it)

silicone couplers and clamps 100 (all over)

HKS SSQV BOV 325 (used) for low boost setups use a audi, saab, vw or dsm stock BOV, they hold low boost fine and can be had for around 5-10 at a junkyard

lincoln 80mm Maf 20 (junkyard) I have a lightning maf , just not installed yet 45

for what is on my car currently, that's around 1500 with a cheaper BOV, no intercooler(which means less piping, couplers and such), looking harder, and doing the work myself, I could remote turbo another sho for less than a grand. the problem is, I have no need to do it again. lol

I wish you lived closer to me. lol

I wish you lived closer to me. lol

lol I can understand that.

I rarely post on here and the reason being is because 90% of the forum has it stuck in their heads that boosting a sho is gonna cost 4-6 grand, and my setup was way less than that. But no one wants to listen to that, so I just stopped telling it.
The funniest part about it is, I have redone my piping at least 4 times now, I've had 3 different turbos already and I might be buying another one soon because I have a line on a new one in the same size I have basically,(a ball bearing turbonetics and it's only 350, current one is journal bearing). I've had numerous different setups and I still only have right at 2,000 in it and that's including all the parts I've bought for it. The quiafe was the most expensive thing I have bought for it, followed by the pistons, then followed by the tweecer. now that doesn't mean I haven't spent a pretty penny on the car but still.

now that I have stated my part, I will say this, It can be done with better parts, or lower quality parts. It just depends on what you want. for instance, I have a mountain dew livewire bottle as my oil catchcan coming from my PCV and CCV. most people find it tacky, but I find it to be lightweight, easy to drain, and cheap to replace every few years(it was originally a dr pepper bottle )


The other funny part is that before my car was finished, there was this huge debate over whether a remote turbo would even work. Everybody flamed everything. So I got it done, and posted video before anyone knew it was even being started. It was more of a haha it works kind of thing. None of the naysayers responded at that point...

 

[Jh8990]

thats pretty cool man. kudos

 

[Northwestvoodoo]

Well,,, I was gonna say talk to strings1732 but I see he piped up. Even thought I run a Vortech, I always liked the remote setup idea. Maybe I will give it a go in distant future.
If your wife wants a hard number for this project...... it may cause you problems. As I understand it, strings1732 fabbed up his system. If you have some skills, you may pull it off on a low budget as well. Regardless, once you have driven a boosted SHO you wont go back. I hope you can pull it off.

By the way strings1732, good job on being the first to remote. It's hard to pull off a "first" in the SHO world.

Like I said I don't post much. lol

Thanks for the compliments. It is never easy to be the first to try something new in this community because there are so many people who think it won't work or that they need dyno numbers before putting money into it. The fact of the matter is, research needs to be done to make the part, and numbers will come later. But in the current state of the world, (most)people won't just throw money at something unless they have hard evidence that it will create a substantial gain. Currently there are only a few people that are willing to throw a large sum of money into the R&D to figure it out. And to all those people throwing money around, I say kudos to them.

I realized after long and hard thought(and a lot of money spent on nitrous refills), screw the naysayers. I'll make it work. and now look at how many remote turbo sho's are popping up. I know of at least 2 currently, another one is almost complete and possibly 3-5 more in the works....:woo-hoo:

 

[SHOCarGo]

thanks people i will check out the links about it. and if i did all that (what strings1732 said to do on the parts list ) what kinda hp would i be looking at? and i going to start on this project as soon as i get the right info.. and i might post a Thread about my progress if there isn't one all ready

 

[strings1732]

i also forgot you need to use an oil return pump to drain the turbo after the car is off. i have a tilton differential pump to drain mine. sure flo makes a really good one though. also with 6 to 10 psi, you should expect, with a proper tune of course, anywhere from 280 to 350 hp. my original setup at 10 psi with tons of problems did 367 iirc.

 

[SHOCarGo]

so i need an electric oil pump, to get the oil back there and one to drain it? and what about the coolant? because my other car(turbo too) uses water and oil

 

[HotRodKid]

electric oil pump to pump the oil BACK to the engine

go w/ a turbo that doesnt have water cooling, otherwise youll need an electric pump for that also. the stock water pump wont move the water that far because its not a positive displacement pump

 

[SHOCarGo]

so i don't need an oil pump to get the oil there, just back. so is the turbo going to use the cars oil or should i make an self contained oil system for the turbo. like have its own oil reservoir, oil cooler then the electrical pump, then tap the pump into the cars hot leads so that when the car is on the pumps on(i know not to run the car with out the pump on by by turbo)

and i was looking at some forums and was thinking because my turbo in the back, it s got a lot of room to fill before spooling up the turbo, should i go with a stock diameter exhaust or little bigger or smaller


**** what about I/M and state inspection

 

[strings1732]

The pump merely helps scavenge the oil. The reason for the necessity of this crucial component is that a turbo oil return line typically works with gravity. When the turbo is lower than your oil pan, or your return line goes uphill, you need to scavenge the oil out so that it does not leak past any seals(this will ruin the turbo seals). invest in a turbo timer to install on the pump(not on the motor) so that once the car is off, it will drain the oil out of it. Or you can do like me and just turn the key back on without starting the car.

I am running 2.5 inch exhaust to the turbo and then 3 inch after. It starts spooling at about 2,000 rpms. However, stock exhaust would work fine for a low boost setup.

I would get the car inspected and pass emissions in it. Then throw a catless y-pipe on and no worries. Come emissions time, swap in a stock y pipe, go pass the emissions test and then put the catless y back on asap. You do not want the catalyst blowing out and into the turbo. That is how you destroy your motor and your turbo.

 

[SHOCarGo]

k well i looking up parts i need for this project...


where can i get the upgrades fuel injectors

 

[LOUDSHO92]

Here: SHO Source

You will need a FPR, fuel pump and injectors. Tuning is needed for the injectors.

you could jsut wait for the Turbo kit...

 

[christiansho]

lol I can understand that.

thats the old motor. Now an exhaust after the turbo has been installed and it has a new turbo on it. also that run had exhaust leaks and(as you could tell from the blowing smoke) something wrong with the motor. I'm now running more boost and a way better tune. Today, while tuning, I got my wot fuel multiplier to 1's across the board. And I'm still running a little richer than I want to. only hitting 68% duty cycle on my 44# injectors at full boost too. I'm going to bandimere tomorrow so I'm hoping for some quicker times. I've still got an exhaust leak pre turbo that needs to be fixed so I'm not spooling quick enough in 1st. I should have that fixed in the next week or so though
