am i ready for 50trim?

[rowdygst]

well since im a noob the forum wont let me post antwhere else so i tought i might as well post here, mods move it if needed..

i have a 1990 gst it has wiseco pistons, eagle rods, acl race main and rod bearings, new crank, arp headstuds, cometic headgasket. the motor is being put together as we speak. i also have a wideband, evo 560cc injectors and safc. and as far as bolt ons im running a 3inch open dp and aftermarket 02housing i also have a fmic that hasnt been installed..

so my question is based on those mods, you think im ready to go to a 50trim turbo? right now i have a big 16g, but my friend offered me a pte 50trim on a evo 3 manifol for 300, the turbo is used but it dont smoke or have any play with it.. so should i jusmp on this or based on my mods ill have more power with the big 16g...the 16 g never seen past 15 psi, so now im planning on eiter gettin meth kit, and turning it up to 25psi or get dsmlink OR get the 50

what are alls opinion

also i know that pte has a bad rep, but my brother ran one with no issues for years and so have other friends, so goin with a pte its kinda like a 50/50 chance sooo idk

I would max out your turbo. What are your goals with the car? I recommend you get dsmlink or a reflahable ecu to get better results with your car

 

[bryzenga]

I'd say stick with the 16G for now, but if you decide to go with the 50 trim, you would be looking at wanting to get bigger injectors as you would more than likely max them out fairly fast. After bigger injectors, it would be advisable to get link. The SAFC, if I remember, can't efficiently compensate for injectors that are bigger than 660cc's. So basically, if you get the 50 trim, you will want to invest more money to make it all work good. Still could run it with your setup, but will more than likely hit a 'fuel ceiling'. Just some things to think about...

To take advantage of a 50trim...at those current mods, your not ready.

50trims dont come alive until at least 20+ psi

You would need at least
*upgraded fuel pump (recommend rewired Walbro 255)

*if you get a 255 or bigger, you'll need an AFPR (adjustable fuel pressure regulator)

*bigger injectors, if you get dsmlink, get the biggest you can get, incase you upgrade turbos again later
(650cc is just about maxing out the safc)

on a side not, if you have local access to e85 fuel, you should definetly start setting yourself up for it if you wanna make good power

 

[scott90gsx420]

I say run that 16g. I have semi-same mod list as you but with a walbro 255 and afpr set to 46psi at idle . Ive got evo560cc injectors and a big16g running 22psi and its pretty mean. If you haven't even maxed your currrent setup out why start moving to a bigger one?

 

[rowdygst]

ok i knew i forgot something , i do have a walbro 255fp, afpr, and i have denso 750cc laying around, the only reason i didnt installed them its cause i have a safc and i know that i cant tune with anything bigger than 650's...so all i really need is dsm link.

im looking to gettin 400-450whp on pump and meth...there are a few e85 station in my city, but none close to where i live..the closest station its ###### 30miles from my crib, and this is my daily driver so i rather stick with 93 and meth, and on another note, my friend droped the price so im goin to pick it up friday

 

[DSM_PWR]

ok yea if youve got fuel mods already, you'll just need dsmlink and a good tune

 

[90tsiPA]

Don't forget that you are going to have to get an oil feed line oil drain and figure out the way you are going to block off your coolant lines as well as modifying your charge piping and possibly your intake.

 

[rowdygst]

where can i pick up the oil lines? whats a good way to block the coolant line? the chage pipe and intake modifications its all good, i got a freind that does some good fab work, so he can help me out with that..

also its better to feed the turbo from the OFH instead of the head? and what size restrictor should i run?

 

[JusMX141]

560's and the AFC are going to hold you back from ever making power with the T04E50. You need more injector to run enough boost to make an E50 worth having, and you're already aware that your AFC will prevent you from effectively tuning anything larger than 650's.

You haven't really started modding the car yet- so what makes you think you're ready for a T04E50? I'd think you would want a "baseline" of sorts for the rest of your build. Used 16G's aren't getting any less valuable- you may as well run it.

 

[rowdygst]

well i figured my as well jump to the 50trim since i already have 750cc injectors not installed, and in 2 weeks im gettin dsmlink and meth kit, i know that the big 16 cant meet my goals of 400-450whp, so my as well jump on this awesome deal im gettin and mod the car accordingy to meet my goals, i have a built bottom end, i got fuel pump 750cc, so with dsm link i should be good to go, so anyways i bought it already all i need is the oil lines and im good

is there a place where i can buy the oil feed and return lines for the 50trim turbo?

also, i have a journal bearing , so where should i feed it from head or ofh?? i read mix reviews on that

 

[rowdygst]

ok im having second toughts on runnin the 50trim with the 720cc and the safc..so i mihgt use the 560cc meanwhile and meth till i can afford dsmlink...any toughts on this?

 

[army94e]

The set up you are running now is a great one. I think you should stick with it, but still get link and fine tune it. You can reach your power goals or come really close to them if you use link and the larger injectors with your 16g. I know having a large turbo is sweet and all, but IMO I'd stay with the 16g, 720's, and definitely get link.

 

[rowdygst]

I just don't see many big 16g turbos past 300whp unless is the evo 3

 

[army94e]

My bad, I assumed you had the evo3. I would still stick with it for now, just max it out and see if you still want to upgrade to a 50 trim later. Its like we all say, it depends on goals.

 

[overboosted1g]

If you have to ask then no just stick with a 16g.

Man what ET are you getting now? low 12's high 11 are attainable.

 

[rowdygst]

i havnt gotten any track times cause motor is still being built, just waiting on my clutch and ill drop it in, but im not to worried about 11's or any et's i want to trap at least 110mph thats what im worried about, cause i hardly go to the track

anybody interested on buying my pte 50trim cheap?

i would refrain from saying things like that on this board...they dont look to strongly on racing not done at a track

 

[rowdygst]

thanks

Kind of irrelevant now, but to answer your question:

Yes, you would want to feed it off the OFH. Also, the best way to block the water lines would be:

1G NT water pipe
1G NT thermostat housing

And to block the oil feed from the head, use the plug also found on a 1G NT.

This way you have a super clean setup, without plugged hoses running around.

 

[RogueTalonTSI]

On a fresh build motor I would break it in on the 16g and learn how to drive your set up first, the best upgrade is the nut behind the wheel. In the mean time I would suggest investing in Link and learning how to tune. For an example here is my set up:

Turbonetics 50trim fed from the filter housing @ 22psi
FIC 850cc
DSMLink V2
Wally 255 rewired
AFPR
Short route FMIC
MAFT w.3.5" GM mas
Full exhaust
BC 272's


I see full spool around 4800 rpm and run 70% inj duty cycle so plenty more room for boost. I get a hard spike, around 30psi but it quickly settles back to 22psi. My set up is built for SCCA racing. Honestly I would like to switch to e316g and drop to 650cc injectors and 264/272 cams and try to get a little bit broader power band... Just my .02 cents

 

[rowdygst]

yeah im already looking to sell the 50trim and stay with the big 16g, im thinking of pushing 22-23psi on 93oct and meth on the safc while i save for dsmlink...im thinking i would like to upgrade later to the hta68 to remain a fast spool and still have top end ..so here is the new set up let me know what yall think

big 16g
560cc injectors
fmic
3inch dp (no exhaust)
walbro 255
stainless steel 2.5 02 housing
ported 2g mani
wiseco 8.3:1
eagle rods
xtd stage 4 clutch with 11lbs flywheel
aem wideband
hallman mbc
cooling mist meth kit
safc

those are the parts i have right now, does it sound like a legit set up for 22-23 psi on meth? around 300-320whp?? like i said eventually ill buy dsmlink throw the denso 720cc injectors i got and once i leard how to tune and buy cams, maybe MAYBE ill buy another 50trim and throw it on there.

Any guesses

 

[RogueTalonTSI]

You should still upgrade your injectors so your not maxing out your injector duty cycles but besides that your set up sounds legit

 

[rowdygst]

Yeah im gonna stick to 560cc until I get dsmlink which should be in about a month or so, then ill use my 720cc...
