how well would an sts turbo work in a single front mount
i was woundering how much the turbo for the base kit from sts cost and how well it would work in a single front mount on a stock LQ4 engine.
TO4E 60-1 Trim .81 A/R Garrett Turbo
i ask because i might be able to get a great deal on one right now.

I have never done it, nor have I seen it done. I do know that turbos are matched to their surroundings. I believe there is a FAQ on the STS website that covers this. Basically saying the turbo they use as rear mount will not work well as a front mount and vice versa. I would imagine it would boost, but I think it will choke the exhaust flow at higher RPMs. Then again.....it might be the best thing since sliced bread, I never tried it.

You can put this turbo in front but you won't be very happy with it.They are on the small side and the ar ratio is small to aid spool time mounted in the rear.If you are going to the trouble and expense to do a good front mount you will be much happier with a turbo designed to work in the front.The results will be worth much more than the small amount of money you will save.

Well I think it all depends on what Size turbo you go with.. a Base kit STS turbo used in a front mount application will be very unfriendly.. Because its a t-60 turbo.. Most guys I see going front mount are using gt-76 +....
You can However get the gt-76 from STS... Or maybe a gt-67 w/ a .96 a/r housing..
I really dont know how you would make up for spool difference and exhaust flow...

STS mentions them constructing "custom" turbos for their kits but they are really more of just a standard 60-1 with specific housings. For the most part, they would work in a front mount situation given they could flow properly for the given cubes and not cause back pressure issues. In the end, there are better options out there regardless.
In your case, a 60-1 is a bit small for a 364. Go with at least a T67. Personally I would look at a TC72 or 76. Give forced inductions a call. Theyre a sponsor and can help you make a purchase.

yes i thought it was small myself so thats why i ask, i can get a brand new one never used for 400 bucks and only would shoot for 500rwhp at most because of a bone stock engine and i have a 125 dry shot i planned on adding on top of the turbo once it went forged then mybe going with a bigger turbo after all that. so are you guys saying it would spool great or not so great, im looking at not spinning the motor past 6000rpm and want fast spool and around 500rwhp with it. I had to ask as i dont want to miss out on a brand new $400 turbo, though i dont know how much it cost new.

Yes it would spool very fast,but it would be done on your stock engine by about 42-4500 rpm.It probably wont make five hundred hp either.This would be a little better idea if you were looking at one of the sts upgrade turbos like a gt 67 or 76 but the 60-1 you are talking about simply isn't big enough to meet your goals,you can do much better for a little more money.

i was thinking of picking up a secound turbo to go with it but i like how simple a single turbo would be and how cheaply it could be done, i guess i will just get a monster sized turbo later.

There is no need for a monster turbo, it's just that the flow chart for a 60-1 is incompatible with a 6.0 liter engine. You could do a heads/cam 6.0 and make around the same peak HP as with that turbo on the same motor. I will admit that the torque curve would, however, be DRASTICALLY different. The bottom line is you have two good choices. Either learn everything about turbos, or consult an expert in designing a system. There are other choices that "might work" including, but not limited to, reading product advertisements or just randomly putting parts on your car.(drunken rant mode off)

I did this with my truck and the 4.8. The turbo is the standard t-60 and I had put the .68 exhaust housing on it to help it spool when it was out back. Then about a month ago, I built a custom front mount setup and moved the turbo from the back to the front just the way it was. It made a HELL of a difference! It spools very quick and makes great power. The .68 housing is a bit small, a .81 would be just about right for my motor. I run 7 psi in low boost and 12 in high on the 4.8. The motor is stock with only a Vince ultra torque cam, and meth injection.
I live at high altitude (4800) and had been having trouble building boost brake stalling it on the line at the track. With the stock STS with pipes wrapped, I could only get about 1-2 psi on the line and ran a 14.59 at 99 in my 5500# truck. After I built my custom front mount and moved the turbo, I when back to the track and ran a could build a full 10 psi on the line and the truck ran a 13.2 at 103.5. When from a 2.39 60' to a 1.95 60'. A hell of an improvement .
Based on my weight and trap speeds, I should be very close to 500 rwhp with the little 293ci motor
Here is a link to the thread where I did this.

Now thats what I call valueable info from someone whose actually done it!Sounds like it worked great for Kbracing96.On your ta though you are working with less weight,more cubic inches,and you dont have a turbo already.If you already were invested in this turbo it might be worth experimenting with.But starting from scratch,get a bigger more suiteble turbo for your application. The BEST thing to do is talk to the turbo experts to get their suggestions for your goals on your car and don't do any guessing or you might spend lots of money and then hate your results!

A T60 will flow enough air to make around 500 hp. On your LQ4, with a .96 a/r housing, at about 5 psi of boost, it would be VERY responsive and virtually no lag and be a lot of fun to drive . You can alway sell it later and go bigger, but personally I like to have something that is fun to drive even if I have to give up a few hp up top. I'm not looking to win any dyno competitions, I want some thing that boost fast and kicks *** on the street, which is where I drive my truck. Dyno numbers and drag strip times are for people who like to internet race

The .96 housing is key there. A .70 or possibly even a .81 could cause pressure issues and lead to high ECTs, blown head gaskets, ect. I noticed a drop in KR and better temps all around with the addition of the .96 housing but it spooled over 500+rpms slower than the .70 which hit full boost at 2500. This is all in a rear mount.

I would not run anything less then a 72-74mm on a front mount LS1. A TC76 will spool around 3000rpms...lol. Unless your looking to pull up stumps and no more then that is fine. But if you want power to the redline, your way under shooting what you need.

I am wondering about the 60-1 as well. I am planning on building a TT set up using 2 60-1s. If I was building a single T setup I would probably go bigger, but I'm thinking that twin 60-1s will work nicely.
I thought I read a thread somewhere about someone making 900+whp on twin 60-1s on a 370...?
