20g or 50 trim

[LA97GST]

I want to run high 12's in my 1997 Eclipse GSt. I have all the supporting mods, but I need a turbo! I'm thinking about either a ported 20g or a 50 trim .48 ar. Both would be externaly gated hopefully. Which of these if any would be best for a mid-high 12 street car? And I want to save money .

Get the fifty trim with a .63

The .48 does not provide enough topend, which is what your going to want in a fwd.

 

[LA97GST]

-49 lb/min compressor
-50 trim T04E compressor
-76 trim T31 turbine wheel
-T04E (3" inlet, 2" outlet) compressor housing
-Setup for manifold mounted or O2 mounted external wastegate

will that be a good street turbo? This is on AGP's website. Can i choose the ar? i guess i want .63.

either turbo could run a high to nid 12 cake... i'm saving up for agp's RS 49... those are good for 11's

The PTE turbos from extremepsi.com look like badass deals. $1k for everything I need to go from a t25 to a 50 trim. That's what I'm saving up and building up for.

a bunch of people bad mouth PTE turbo's, but i dont have any experience with them .. or any turbo for that mater .. still rockin the 14bizzle .. haha... like i said i want to go with a rs49 from AGP... but my bud told me that PTE was making turbine housings for AGP for awhile ... so i would say do the shoppin

3. No "X"-Turbo vs. "X"-Turbo threads... these are never useful.

I think this was more of a "which turbo would be best for my application" thread ... i found it very useful, as i was considering the same two.

I believe i'm going with a PTE off of extremePSI... they are great deals and are nice turbos as well...

i also went with the 50 trim from extreme psi, mine is internally gated and has all the supporting mods necessary to hopefully turn high 12's, but i am having trouble boosting with it. i just took it to the dyno to tune it and i wasn't able to boost above 14psi, i have a greddy profec-b and that wasn't changing anything, then we ran the vacuum line from the manifold directly to the wastegate to let the turbo have open boost, but still help around 14psi. we then did a pressure test with the wastegate and found that it took 40psi to completely open the gate, which seems ridiculous, anyone know anything on this. anyway the turbo made a mild mannered pass of 255 whp, which i was frustrated about cause i was hoping for around 330 whp @20psi. the turbo does feel amazing though, even at 14psi.

When you see a civic with its wheels blown off, It's fitty... it's fitty...

you shouldn't throw stones if you live in a glass house and if you got a glass jaw you betta watch your mouth cuz Ill break ya face, have your ass running mumblin to the J

255whp at 14psi is nothing to be ashamed of. If you can't boost past 14 psi try a leak test and also play with the actuator arm on the wastegate. They have to be preloaded to hold higher boost.

i am def happy with the power no doubt about it, its just that i made 226 whp with the t25 @16psi and i was hoping for higher numbers to start. the tech and i tried a leak test at the shop when the car was on the dyno, but all we found was that we hooked the wastegate up to a air compressor and gauge to read what it took to open and at 15 psi, it was just starting to open and then it went to wide open at 40psi. the guy at extreme (neo) told me that the wastegate didn't need to open all the way since the flapper was soo big and that i should try a manual boost controller, but i don't know how that will help. oh, would i just adjust the nut on the actuator arm to determine where to have the flapper rest...not sure and i just want to boost higher

I'm thinking I want to go with a 20g from SBR with 34mm flapper,ported, and welded elbow on. I don't want to take any chances on getting a bad turbo like the 14 psi guy. I heard that mitsu turbos are more reliable.

Did you not just read that he made 255 whp at 14psi with a turbo that is not even in it's efficiency range until the mid 20's? I'm not knocking mitsu turbos, I have one and I love it, but you have to admit that 255whp is nothing to sneeze at.

 

[camman420]

If he is making 255whp at only 14psi he will be making 300+ at 20psi which is pretty impressive for a 2g with a stock head and intake mainifold.

What spool up on that PTE turbo like? say, compared to a E316G?

i can't compare mine to the E316G since i haven't been in a car with it but i can say that in a FWD, this turbo kicks ass with just the right amount of spool time so as not to obliterate my front tires for the first gear and a half or so, and the other thing thats great is that between shifts (1st to 2nd and 2nd to 3rd especially), there is seemingly no lag and just straight power. and my problem with the turbo boosting is most likely due to a boost leak in my hoses or not having my actuator set right, but either way the PTE .63 A/R seems to spool as fast as most other .48 A/R.

 

[LA97GST]

You talked me into it . I will order the PTE 50 trim with .63 ar from extremepsi. I found they have a good price. What do I need to install it to the 2g? Am I gonna need the 90 degree passenger side elbow welded on to fit to intercooler pipes? Also what oil and other lines do I need to install it?

 

[GSTspyder98]

the 2g install kit that comes with it @$995 comes with the ss oil feed line, gasket and bolts necessary for install, i did get the 2 1/2in 90 degree elbow though and it mounted perfect. the only thing i ran into was that since i don't have slim radiator fans so i had to move the primary cooling fan about an inch to the side to accomidate the internal gate, no big deal. i'll post pics of the install and how it sits along with my dyno charts for you if you want

 

[LA97GST]

that would be awesome

Please do! I'm looking at getting that exact same setup in about a month...

At what rpm do you start feeling the turbo, ? Like when does it start spooling and let you know its there ?

dont even bother with a 20G it is old technology. It still uses the mitsu 7cm2 which you need to port the HELL out of to fit such a lagre turbine wheel. A TDo6h 20G will cost you $1100 for an internally wastegated w/ 38mm flapper, 90* elbow, and porting (prices from SBR). On the other hand, if you get a T3/T4 50-Trim not only does it flow more, it requries no porting, bolts up to stock e.mani and o2 housing, and cost less. I got a 50 Trim internally wastegated w/ 38mm flapper, 90* elbow for $950, plus an install kit for $100 bring the cost to $1050 which is LESS THAN a Tdo6H 20G

Old technology does not have any bearing on functionality.
