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

[dsm-onster]

A little of topic but i have a friend who made 350whp on his evo16g with a motor that is set up to run a fp3575 on pump gas at 24psi. then he was tuning the car at the same psi but on race gas and he was only makng 335whp. now i know he should have turned the boost up when he was using the race gas but why did he make so much less then when he was using pump? I don't see how it wouldn't be possible to make 400whp on an evo16g on pump, it's all in the tuning. And i always thought that people used race gas to create a safety margin when turning up the boost?

I believe it is posible to make 400whp w/ an evo3 16g, if you add water injection.

The green is bolt on turbo The green is a 50 trim version of the red. Everything WILL bolt right up to the green the same as it would with a 16g depending on what kinda wastegate you decide to use.

i could NOT bolt up the green and run it as my car sits right now.. the comp inlet is 3" on a green.. the 16g inlet is the same size as stock... everything else would bolt up though..thats all i was saying.. and i dont have a aftermarket intake yet.. just the k$n filter.

and i would have NO proble running water inj or whatever inj system w/ a 16g to TRY and make 400hp.

 

[Forces32psi]

so i just called forced performance and orderd the evo III big 16g ported w/ new gaskets shipped for $644.. im hoping this thing wont boost creep like crazy since i have the 2 1/2" steel O2 housing w/ dump and 3" turbo back exhaust..... and il be getting a water inj system soon FUN.... anyways.. are those evo 580cc inj. worth a crap compaired to ball and disk 550's?? can they be SLIGHTLY over run like ball and disk inj?

which turbo will make more power on pump gas...the gt30 (which is the non ball bearing version of the gt30r and flows 52 lbs) or the sc61 (also non ball bearing and flows 65 lbs)...i can get 93 octane here if that makes a difference...thanks...

sc61

 

[qtxdevilz]

so you guys are saying that a fp3052 (which is a ball bearing gt30) will make less power than a sc61 on pump gas...alot of people regard the fp3052 as the best pump gas turbo...i would think the sc61 needs more boost to make more power...and more boost means race gas on a sc61...let me know what you guys think...i just want to know which one will dominate the streets...

A buddy of mine ran 13.5 in the 1/4 on 14 pounds of boost with his sc61. This is with a stock bottom/top end with stock cams and intake manifold. This was also with some massive boost leaks (we later found out), his timing was out of control (25+ advanced because he didn't have his gm maft set up correct), and as a result some knock on the run. By the way the boost leaks were so bad when we did a boost leak test we couldn't get any more then 5 psi to hold.

He has since fixed all the problems, threw in some 100 ll and turned the boost up to 21 psi I think and went 12.6. I think he probably could of pulled close to that time on pump at 21psi with a little less timing. This is all at 4200 ft elevation.

IMO, SC-61 is not meant to be used with pump gas. I think you can get more from a GT30 on pump without meth/alky. If you're gonna get an SC-61, you might as well go with ball bearing, 35R. Trust me, it's a hell of a difference.

Why is everyone hung up on efficiency? The SC61 might move air that's 5 or 10 degrees hotter than the GT30R, but the simple fact is it's MOVING MORE AIR, and if you have a proper intercooler you will make more power on pump gas with the SC61.

We moved from a PT66-GTQ to a PT76-GTQ on a friends supra, and running an air/water intercooler the inlet temps were virtually identical. The PT76 outpowered the PT67 by about 85 WHP at 20 pounds of boost, even though the PT66 was running in a more efficient part of it's compressor map the larger turbo was moving more air and making more horsepower. It's kind of like how people on here are recommending 50-trim's over SC61's and larger turbos for the most pump gas horsepower, I just don't buy it. Buddy of mine made over 500 WHP on 93 octane with a 1.8L honda motor and a T3/T67 that was supposedly way out of it's efficiency range, there's no way he could duplicate those results with a GT30R.

Why do you think the sc61 is not meant to be used with pump gas? Its a street turbo. People normally run pump gas in street cars. Therefore you have a pump gas turbo. And I didn't notice much difference at all between my sc61 and the 35r cars I've driven. Maybe a slight increase in response between shifts. Do you own an sc61 or a 35r?

Had:
EVO III
20G
FP Green
SC-61

Now:
35R
70-trim

All ran 110 octane or higher. Like I said many times before in other related posts, the SC-61 comes alive @~25+. In my experiences, seems like the 35R lasts longer too. For sure the SC-61 on 18psi did not surpass the Green @27psi. Does that help? You guys are the ones with the experience, right?

There are way to many variable to be able to determine which is going to be better on pump gas for your setup. Both have been proven to make near 500whp and run 10's. If you want the quick spool get the GT30, if you want a laggy turbo with more top end get the SC61

like the title states, 2.0L, no alky, pump gas, 8500 rev limit. opinions or #'s on your set up

I'm running the Turbonetics 60-1 turbo on 93 octane gas and couln't be happy with the powerban it puts out. With the .63 A/R, I don't hit full boost untill about 4k, but when I do, it pulls unbeleivable hard.

Turbonetics 60-1 T3/T4 Turbo
----.63 A/R
----Stage 5 turbine
----Super 60 Wheel
----4inch inlet, 2.5inch discharge

Here is a little video of the turbo and it whislting at you.

I don't have any numbers on it yet, but I hope to get some results here soon!

Sounds nice alex too bad the video doesn't show the car though. Keep us up to date with #'s

Depends on what else you're gonna run....cams? intake? exhaust? The list goes on and on.

FWIW, i just got my 20g on after stepping up from a 14b. Also have meth injection, fmic, 660's eprom 3" exhaust,etc. Stock cams, stock 6 block and intake mani though.

That 20g pulls like a freight train and liquid smooth!

I have no numbers, but its very,very quick.

Do you have any footage of the beast?

I'd go with a FPgreen. It has been one of the best(if not the best) pump gas turbos for years.

 

[andymoraitis]

I agree with everyone's statement above.

The 60-1, 20G and FP Green are all amazing turbos on pump gas. Keep in mind that something with a large housing and inlet will heat the compressed air charge less than a smaller turbo like a 16G variant. In that vein, 50 trims also work well on pump gas as would a Holset.

The key to making it work is not necessarily picking the largest turbo, but one that you'll be able to run in it's efficiency range, tune easily and support properly. It's better to have something a bit smaller and tune it to the optimum than have something huge and only support 15psi because the proper fuel and tuning mods aren't in place.

Just my .02

P.S. Beautiful motor setup Alex

I second this ... External gated FP Green one of the best pump gas turbo

specfics eh, 880's, maybe set of 272's and a cyclone, aem or dsmlink, 3 inch ex and of course the same old song and dance mods. Nothing too righteous just a nice little street car

 

[AL92]

My AGP RS49 not RS49 T was great turbo on my 92 2.0 talon but they don't seem to make them anymore.
If I had a 2.0 still I would go for a FPGREEN OR FP3052 leaning to the 3052.
Since I went to the bigger 2.4 engine the FP3065 was my choice. It can hit full on the 2.4 around 3800 or so. But on a 2.0 it would be in the 4000s.

 

[Precision]

^^That's odd, I'm hitting full boost @ 3600 on a 2.3. ^^

As far as the best pump gas turbo on a 2.0 any FP 30 seires. Awsome spool and hits harder than Mike Tyson. People are seeing WHP in the 500's @ 20-22 PSI on 93 octane with some what agressive timing.
