Sts remote rear mount turbo kit.
 

I just got back into a F-body after building and driving a 402ci Stroker in a G8 GT for the past couple years.

Bought a 01 Z28 Vert that I'm planing to use as a summer DD and I don't want the car to be down for more than a day or 2 at any given time.


So I have an opportunity to purchase the following a STS rear mount kit with upgraded Garrett 70mm plus alky injection meth kit with intercooler for around a grand or so.
It's a bigger turbo but can be ran at lower psi(5-7) with out the need for the cooler and meth kit.

I was debating about dropping cash on LTH, ORY, minor bolt on's and an Exhaust that would cost about the same.

I already purchased a racetronix fuel pump,with low PSI do I need injectors? I plan to tune the car either way. Is a "boost" cam needed for such a setup?

This is a stock LS1 and I'm not looking to do anything more than find a few ponies and I'm not planing to rip the motor out until next winter.

Just looking for some expertise as I've been out of the ls1 game for some time now and these where fairly fresh to the market back then.

This place really has died down"sarcasm", any one have any positive input?

Do bolt ons.

Auto? Do a nice converter too

General consensus is that they're not a crowd favorite. I know a user here, firebirdcrazy, had one on his car for a few years but has since upgraded.

I personally can't comment on any of the tech aspects of your question, but once everyone gets inside the house again today I'm sure this will get more eyes.

I know you said you are looking for "a few ponies," but can you expand on that a bit further?

Four hour window on a beautiful day....

I've always wanted to try the rear mount kit personally. Would this be your first force fed car?

Sarcasm lol, I've been outside most all day myself.


As for the car I'm just looking for bolt on power; either it be the sts kit or "bolt on's". I'm not looking for a certain HP number nore do I want a track beast. Traditional bolt ons and a tune can net what 25-30 rwhp? Would the turbo kit would nullify most of those and net 50-60 rwhp at low psi?(capable of much more)

In the end I just want a fun summer ride for the time being, maybe hit up the track a time or 2 and some shows.

First car that didn't come stock with a turbo
I figured the sts kit could be something fun to play with then possibly next winter do a real turbo build as I plan to pull the motor then anyways.

I haven't found any real negative input on this setup(many hours on the Google) but I haven't found a whole lot of positive either just a few build threads. The worst I've foubd so far is the oil return can be a pita but a separate reservoir seems to fix that.

Have you found anything positive regarding their performance?

Its definitely seems like a straight forward install. Any ideas on the future build and would include the bolt ons or the rear mount ?

Persoannly I would do the rear mount but if this winter you are going to ditch it I would say forget it and just save

Haven't really found much one way or the other besides the build threads I've come across, some people say they are gods gift while others say it's all bull. I did find an actual Dyno video that showed a decent pull near 380 rwhp with the kit.


If I did the rear mount I would keep it installed. The car has 130k miles on it now and is bone stock. Is the garret a decent turbo, does it have potential if I decided to add the intercooler/meth kit with a proper motor?
The only long term plan is a lq4/9 build over the winter.

I dynoed 425 rwhp with a big cam and stock 243 heads. I'd be mad if a $6k turbo setup only got me 380rwhp.

6k? Looking to spend a grand. I think that run was at 3-4PSI I'll see if I can find it again.

IMO, drop the idea of the rear mount. From what I have read they will nickel and dime you to death chasing boost leaks, hot side leaks, fixing lag issues, and making sure nothing hits etc.

But, if you do decide to go down that route, boost is boost. You cannot approach it with a cheap budget mindset and expect your motor to last. Sorry to be brunt but its a expensive and tough road to go down. Bolt ons are simple and prob much less of a headache than a butt mount.

well im just saying thats what they go for new. For a grand it may be a fun thing to play with, then dump it on someone else in a year for what you have into it. It would easily sell on ebay or ls1tech to someone for 1500+.

If you want a reliable platform, keep the internals stock and do bolt ons.

mtg6486 has/had a rear mount that made 480 at the wheels. Some lag, but booked on the top end. Was a bolton ls1 at the time. Ran low 12s at high mph on radials.

Ive heard they have alot of problems with oil feed lines, (supposed solution is routing through the interior if your looking into it) and also clearance issues (as far as if you wanna lower your car or have any hope of putting that power to the ground) not to mention if you ever wanna throw an intercooler on it that would be a real pain routing the piping. Mind you i have no experience with a rear mount, just speaking from speculation, and the little bit of research ive done.

If the plan is to build a traditional turbo set up later I would just say save the money and skip the rear mount. Put that thousand or so bucks into parts that will feed the end goal of having an engine built for the set up you seem to really want. The money you don't spend now will help you get to the your stated end goal that much sooner and with that much better componentry.

If you are going to yank the motor next winter and don't want the car to be down (or constantly needing attention) this summer I'd go for all of the basic stuff first and skip a budget turbo job.

Thanks for the input every one, I think I'm going to pass on the rear mount for now unless I can get it for under a grand.

If it's a steal it might be worth purchasing just to sit on for a little bit

Personally not a fan of Rear mount set ups. Laggier than traditional set ups, a lot more headaches as mentioned chasing leaks and keeping things cool/hot.

Especially running a bigger turbo outside of it's efficiency range (very low psi) you'll have a poor powerband, which when combined with a rear mount set up will compound the problem.

If you're only looking for 380-400whp, full bolt ons, small cam, and a tune will get you in that range and will be much faster than 380-400whp with the turbo set up you're considering. With a cam in that range as well the car will retain stock driveability, just with more power across the rpm range.

Thanks, bolt on's are what I'm looking at now.

I was debating about picking up a 228/228 .588/.588 114LSA cam but with a cam comes new pushrods and valves at the least. Then you might as well toss in a ported ls6 oil pump with ls2 timing chain since it's off. then you get into that mind set of "if I'm going to do this then might as well" next thing you know you're 3-4k deep with a monster lol.

I have a 01 so I'm assuming it still has the stock ls6 intake with 241 heads, might pick up a spare of each and get the intake/TB ported and do a valve job on the heads.

no need to do new valves with a cam
