The best Pump Gas "Turbo" set up? [Merged 5-7]

[Ryan95tsiAWD]

why o why did I buy the big 16g less than a year ago.....

thanks guys for the info

 

[DSMJim]

Throw it on ebay my friend. That will cover at least 1/2 the cost of a new turbo...

16G on Ebay

Im pretty sure you can get that from Buschur @ www.buschurracing.com

and badgsx the turbos are completely different. They are made by different companies, different housings, and Im not positive but I think the wheels might even be different.

Whoah, your hood didn't close with the turbonetics manifold and a tial wastegate?

 

[larryd]

The way the wastegate sits off of the turbonetics manifold it will hit your hood. The hood will close but it will put a small little dent in the hood which will eventually rust out.

Great thread. Going on 3 pages with no hating. I have similar goals. I'm building a good breathing 2.4 with Alc/water injection and pump gas. Would this allow me to reach the efficiency range of the GT based turbos? We've been waiting for the L2R, FP-3055, and PTE GT series turbos for a long time now. Now they are here, and I see people going back to the standard wheel Garretts. Do they need a 25lb+ pressure range to operate in or is it a flow issue?

Hmm.. I have never heard this that's not a good thing. So where exactly on buschur's site is that adapter plate? I looked pretty well all through the side and couldn't find a damn thing...

How come lots of people have this manifold with a tial wastegate and have never said this happens? Are you refering to this manifold with a delta gate hits the hood or it does with a tial as well? Just wondering as the tial is not as big around as the delta gate is.

Give Tym a call.. Bushur only puts like 10% of their parts on the site. Great source for "odds and ends".

Back on subject.. I spoke with PTE yesterday on their new setups. It's still early in the game and the R&D is ongoing. Case in point.. they have a new batch of housings comming out with even larger W/G passages and machined to accomodate larger internal W/G pucks. They also have "GT" setups and a TO4B Comp housing forthcoming which will give much quicker spool w/o much sacrifice in top end.

Mike's setup also looks promising.. and as a Builder/Tuner.. sure to be a winner. Can't wait to see some test results.

Anyone need a test mule ?

That's a very good question, and one that I'm dying to hear the answer to as well, especially as it relates to the "smaller" BB turbos such as an L1R or SBR-GT10. Anybody?

 

[RnR Racing]

I will give all the info I can give without any bias toward either. There have been several cars with good tuners who went from the regular Garrett wheels to the new GT stuff with bad results. All showed less power on lower boost(less than 25psi). This is has been the case with several cars.

I don't know if these cars will actually make any more power at 28-30psi either. Only time will tell if they do. I am almost positive that they will make more power at 35psi, but that isn't where most of us want to run. So right now it's up in the air.






I will say again that the 50 trim is the way to go. It spools great and performs great at pump gas boost 20psi. It also performs great at the track with C-16/30psi.

 

[bigfoot]

I see. What about a 2.4 stroker? Still go Garrett? Different A/R-trim combo? I'm looking for fast spooling and 500hp+ at the crank.

Alc/water injection
Pump gas
23-25 lb. boost

9.1 pistons
Stage 2 street port heads
1 mm oversize valves
264/272 cams
3" exhaust w test pipe
Race FMIC
Forrester Racing intake


Thanks

 

[RnR Racing]

Yes, still go Garrett. I think the 60-1, stage 3 or 5 wheel, .63 AR would be a good choice on a stroker like that. I think the 50 trim would be a little to small for the stoker.

We are selling the 60-1 kit for $1600

 

[DSM90AWD]

RnR.. thanks for all the useful info on the Garrett turbos both in this thread and the others you've chimed in on.

Sorry to be a nag but when can we expect to see pics of the complete setup w/header on your site? Also what does the 4-bolt turbine housing run as an option?

Thanks

 

[RnR Racing]

We are finishing up the final R&D this week sometime. I am hoping this weekend to have all the pics and info up. We will have our final product soon. We already have orders placed for the turbo kits so it will be real soon as we need to get them out.

 

[bigfoot]

Do the standard wheels fit on the GT cartridge? It would be nice to keep the BB center and have the option of returning the turbo to GT specs. Maybe even experiment with fitting a GT wheel to the hot or cold side.

 

[-=TWITCH=-]

Wow this is a great post! I have also reached the point In my DSM life to get a new turbo, To be honest I really don’t know a hole lot about turbo specs wheel size what matters what doesn’t ETC. I was really thinking about going with a big 16g with 2g-install kit from turbochargers.com. But this thread really makes me think twice.

why o why did I buy the big 16g less than a year ago...

I was looking at the

PTE 50trim 995.00

And was doing allot of thinking, I will have about 880.00 when my tax return gets here and when I receive some other money that I am waiting on. Do you guy’s think I should just stick it out and save for the PTE 50trim? Or should I get the Big 16g? Here are my concerns with the PTE 50 trim, I am Wrong wheel drive (FWD) will this really matter? I’m not to worried about traction on the street ill just invest in some nice tires for the street and a set of slicks for the track. I also have a VP o2 housing with External dump will I be able to keep this and use my exhaust setup that I have now? Also is the internal wastegate included in that price? I was looking on there web-site and didn’t see any notification that the internal gate was not include, just thought that I would ask. And one other quick question, what kinda fuel mods are a must to run this turbo? I will not have any money for a while after I buy this turbo. Is there any way possible to Run this turbo on stock injectors and a walbro 255 until I can save for some injectors? Thanks allot for all the help and this is truly a great post. I’m so tired of reading all the Newb posts this really keeps me sane!!!!


Thanks

Just ask PTE, they seem great. I just got a response from PTE. They answered all my questions and seemed very eager to help. The turbine housings are 7.5 cm and 6.5 cm. Buscher claims 500 whp at 29 lb. with the PTE 50 trim that they sell. Here are some of PTE's responses. I told him I would be using pump gas and 23 lb. boost.


What does the SCM designation mean and why are the AR's TBD? Are these newer? What are the differences.

1) SCM stands for Sport Compact Mitsubishi. The A/R's are To Be Determined because they are at Garrett for testing to see what the A/R ratios are.

I read that you were changing the housings, I believe at the wastegate. True?

2) Changing housings? . . . Hmmmm . . . we've been looking at going with a T04B compressor cover to get a little more clearance under the hood. As far as the wastegate is concerned, we're also trying to get a more optimal angle on the actuator.

How close are these housings to the Garrett design?

3) Don't know . . . that's also an engineering question and proprietary info anyway.

Regarding the GT designation: Are these GT series wheels on 360 degree bearings or full GT CHRA?

4) Only a few of the GT part numbers come with ball bearing center sections. the others have Garrett 360 race bearings. Check out Garrett's site at www.turbobygarrett.com to download their GT catalog and you'll see that the only ball bearing they show there is the GT-42. Common knowledge, however, is that there are others out there, e.g. GT-28, that are not in the catalog.

I believe standard wheels may more efficient at my boost levels than the GT series. Your opinion please.

5) No way are standard wheels more efficient. No way at all.

Will you offer a BB center section w standard wheels? Hopefully a Garrett center, possibly a GT? I don't like Turbonetics ceramic version.

6) I don't think so. Garrett GT Technology will eventually obsolete all of the wheels currently on the market now. We think this will take place in the next 12 to 18 months. The only hold up is availability.



Can anyone tell me the best dyno #s that a L2R has put down on pump gas.

The PTE does come with an internal gate. You can run it at 15 psi without upgrading the injectors, but I wouldn't go higher. You are going to need 660's and a SAFC to take advantage of the 50 trim. One thing is that you won't run out of turbo, like the B16g and the little extra lag is actually good on a FWD.
The 50 trim is one of the standard wheels that will not become obsolete by the GT series. If you check it out it is basically the same efficiencies as the GT's. The 57 and 60 trim are soon to be toast though.

 

[Antilles]

Hey Jet, I saw on a DSMtalk thread that the PTE 50 is available with two different internal gates. The person marketing them over there said that one was good to hold boost between 13psi and 25psi, and the other would hold 18psi to 30psi. Which one did you get?

ps, do you have the old suspension out? i may need it in case we decide to break a few things...like the rear shocks.

 

[JET]

I think I am going to call PTE again today. I will definately go with the 18-30 psi one. It has been a while since I talked to them and it sounds like a few things have changed. I sent them an e-mail yesterday about some stuff. I will have the old suspension out next week (spring break).

 

[-=TWITCH=-]

Couple more questions? How does the install go with this turbo? Can you use the stock oil drain line and water lines? And are the turbo's avalible now?

[JET]

They will be out within the next 2 weeks and an install kit of some sort is going to be needed. I e-mailed PTE about the kit and am waiting to hear back from them.
