FP 18g 6SL2

[Luckybob2485]

I have a 96 talon TSI AWD with the following mods:
Team Rip Engineering Transmission
T-28 running about 20-21 psi
Greddy big FMIC
Turbo XS Blow off valve
Act 2600 clutch
Buschur racing 3 inch exhaust
Dsmlink
Precision 880cc injectors
Aeromotive Fuel Pressure Regulator
Walboro 255lph fuel pump
Manual Boost Controller
Dephi Boost, fuel pressure gauges

I am looking at replacing my t-28 with the FP 18g 6SL2. My questions are: Would this turbo, along with my current mods, be capable of putting down 350whp? Also, what all is needed to install this turbo? I will have it internally wastegated and bolted to the stock exhaust manifold. Thanks for all help.

i would say that is a really good turbo for what your looking for. its a little more powerful than the 16g, but still relatively the same. i would go external so you dont run into any possible boost creep issues. also i think you have everything you need from your old turbo to install this one except a j-pipe which are cheap, but dont quote me on that one!

Definitely, 16g's have put down 350 on pump, you should be able to with a decent tune. It's a mitsubishi style comp housing, so you'll probably need a j pipe and you might need to rethink your intercooler piping if its set up for a T-28. Ou of curiosity, how has the TurboXS BOV held up? Have you done a boost leak to see if its holding pressure?

Personally I would go with the 20g instead of the 18 because of that power gain at relativly little cost compared to a 18g. Either will make a very respectable street monster.

Ok first thing is Im assuming you have the Long pipe kit on that greddy???

If so buy the Install Kit from forced performance, and you will get everything you need.
Minus the Silicone coupler from the Jpipe to intercooler pipe. Just ask FP they will have you coverd like a jimmy hat!

Now if you have a Short route pipe kit,
you will need this J-pipe and some form of 90 degree pipe or silicone adapter. again ask FP if your unshure.

And forcertain you will make 350WHP with the 18G. There are a few guys on here making well over 400WHP with the 18G. Some claiming that its a possibility to squeeze out 500!
As you know Your power output is going to be directly related to the fuel type you use, and ofcourse your tune. O and get ready to Crank up the boost! the 18G is a monster at 26+ Psi. Anyone here E85 being whisperd?
O hey one more thing. You might want to check out This! Its a Absolute beutiful manifold.

for certain 350whp with an 18g huh? my car isn't very fast and it has this turbo on it. i say get the 20g or a pte bb 50 trim.

What psi are you running with the FP 18g?

 

[hiimnotcool]

12, creeping to 14.

12 to 14 psi of boost? Are you serious? I would expect your car to be slow. Why would you pay the money for a bigger turbo if you're not even going to use it? That's about the same as buying one and then just having it sit in your trunk or garage.

In my opinion, if you can't run at least 18-20 psi, fix whatever is holding you back and crank it up. I tried my 1g talon (automatic w/ 14b turbo) at 15 or so after having it at 20-21, wow did it seem pathetic -- I couldn't stand it. My 2g eclipse (e3-16g) I wouldn't even think of having under 20 psi either.

Agreed, bigger turbos run higher boosts and push more air cooler and more efficiently, turn teh wick up on that baby. THat turbo is barely even starting to flow air at that pressure ratio.

I run 24'ish daily, but when i do turn it down to "pump gas levels" or what have you (i'm on e85 now) But even then, 20psi is as low as i can go. When i'm at 12-13 psi it's like i pushed pause halfway through spooling the turbo and i'm just sitting there. The only reason i even know what boost that low feels like is because i when i put down a fresh tune i do vac, then boost levels of 9, 14-15, 20 and then where ever max boost is and linearize teh values between those boost levels for a constant AFR no matter what the boost levels

There's a guy on here who made 445 on an 18g 6sl2. Personally i want a 20 (6sl2 version or not) I'm on a t3/4e hybrid 57 trim now and i know i could make the same power on a 20g with faster spool and that's what i want this summer

12, creeping to 14.

You know what, this 12 to 14 boost is interesting because Robert at FP said this:

I'd be surprised if most guys running cat-less 3" exh systems can get the turbo to run less than 23psi in the upper RPM. We have configured this to run like a race horse in the 25-28psi range in order to take full advantage of the bigger 18g compressor wheels higher boost performance advantage over the E316g6 wheel and best match the higher boost performance of the larger TD06SL2 turbine.

Post #13 here: http://www.dsmtuners.com/forums/vendor-announcements/267729-forced-performance-td06sl2-18g-debut.html

In other words your boost should be creeping up to low 20's even if you don't want it to!
Your profile doesn't say anything about a cat. Do you have a stock cat on it or something?
Everything else in your profile looks great to me. I'm really interested in this, in fact I've been thinking about calling FP lately to discuss internal wastegate performance on the 18g and 20g with TD06SL2 turbine.

Thanks,
