Pte Gt37s

[SeanJhn9]

i was just wanting to know if you guys have any experience with or had heard some good stuff about the PTE GT37S, i just recently bought this turbo with the Evo III ported manifold, it is the .63 AR which is a 69 trim i believe, and have most of the supporting mods done. also how the lag is on this turbo etc. my goal is to trap in the 120's in the 1/4 mile and i think this will be the turbo.

Thanks for the info guys

the 37 is a FREAKING huge race turbo.

just for reference i think the 35r has gone like low 10s/high 9s, and your turbo is bigger

WOW can you say turbo lag?

Insert "Got Nitrous?" picture here.

According to your profile, your mods are: " stock....have 2 let the engine break in". What exactly are those "supporting mods" you mentioned?

I went back over some of your old posts, because I couldn't believe I'd missed a discussion of someone doing a build-up to this turbo. I would have been very interested in the results of that discussion. But that's not what I found.

In June you wrote that you had just bought the car, and that you had some pretty major issues with the internals: "my friend and i took off the valve cover and looked underneath and there was shit loose, i think they were the rocker arms".

In another post in August, you wrote: "i want to push the stock engine to its limits...my buddy told me that a stock engine can handle the green turbo, so i might be getting that...but for now i have to stick with the stock one through the break in process.."

Tell me you didn't just go out and buy a big farking turbo (one of PTE's largest turbos, no less) without getting the car even RUNNING properly yet, or doing basic build-up. Kick "your buddy" with all the good ideas in the ass for us, would you?

yeah...just what it says on my info....i bought the car with a ####ed engine for only 700 bucks back in june, and since then...the engine isnt even in the car yet haha....i purchased the engine back in july, and it took about 1 1/2 months to just get the engine shipped out to where i was, and by the time it got here college had already started, and my buddy who is doing the engine has classes and work and shit and there were some other issues with the car...the knock sensor had shit coming out of it and the timing belt cover was also ####ed, and some other stuff, thats the hold up on my car gettin done.

Some of my supporting mods are: ACT 2600lb Clutch kit, Apexi S-AFC, 660cc injectors, Walbro 255 HP fuel pump, Horsepower freaks 3in. downpipe, stock supra SMIC, autometer boost and a/f gauges, mbc....the only thing thats gonna hold me back is the SMIC, as its only gonna limit me to 16lbs of boost...but i still intend on buying an ATR 3in. catback exhuast and other minor stuff like 2nd gen mass and intake pipe, which i probably will end up pickin up this weekend, but eventually i will end up buying a FMIC...and yes, i will do everything else before i throw the turbo and manifold on the car...

I was looking at throwing on a 50 shot, cuz i know lag will be an issue also, but i'm used to it, i have driven and ride in my friends 800hp Supra all the time and he doesnt hit full boost till around 5500rpms, so it wont be much of a difference i hope.

Thanks

I did not think the PTE 37 was a bolt on for DSMs. I thought only the mitsu "street" turbos had the bolt on housing.

 

[DSMTurbos]

pte can do any of thier garret gt and new turbo lines in dsm housings i do believe

So what else are the supporting mods for this laggy turbo? 16 psi on this turbo is going to be different than 16 psi on a smaller turbo. I believe with it being a PTE GT37S, it has a To4S housing on it too? I looked and its rated for 700 hp, so I'm assuming it flows a little more than their SC61. May I ask why you chose this turbo? Its not by any means a small turbo for a 2.0L, unless you're doing a 2.4 and raising your revlimiter up some so you can actually have a powerband when it finally does spool? If all you want is 120 mph in the 1/4 a 20g or 50, 60, or 60-1 turbo is more than enough to do so. In a 1ga, near full weight, I'd say 410-420ish whp is good for your 120 mph goal.

so you dont have 1000cc injectors, a standalone fuel system, a FMIC, or hell even a built bottom end and head?

no, but i will be gettin the FMIC soon...

those are really all my supporting mods, yes, i know it will be different than a smaller turbo at that boost level, but i got it with the TO4E housing, for fitment purposes, but when do you think full boost will be by.....

Thanks

 

[TurboAWD92GSX]

if you had a standalone you could probally tune to get boost by 4-4.5k but i think your going to get full boost around 4.5-5k. i get full boost on my Garret GT40R around 4k. but thats dual ball bearing and i have an ems to load up the turbo pretty good during spool up.

 

[candela]

and we are sure you are the one who tuned it to...ha manny

yeah....thats what i figured full boost will be by....i'm barely gonna have enough for a FMIC, let alon an ems......

thanks for the info

How do you tune with your standalone so that full boost will come earlier?

 

[SeanJhn9]

i just talked to my friend today who was gonna order me this turbo, and he ended up gettin me the GT35B with the TO4E housing and some other stuff.

I'd say probably with a stock 1g (7.8:1) 2.0 woudl spool that by 5+k rpm in like 4th gear. I'd also just suggest getting all the supporting mods first, then choosing a turbo.

by just tinkering with fuel and ignition settings watching the a/f ratio and knock sensor you can get the low end part of your car so fine tuned that it will spool up the turbo faster due to its not running to lean or too rich. also dumping loads of fuel and retarding the ignition timing does wonders for spool up but doesn't do too many wonders on your turbine wheel (might cook it fairly nice). I have hks 272 cams, magnus intake, fmic, 9.0:1 pistons (big difference in spool up from 7.8:1) etc etc etc. mods as well as tuning can help spool up tremendously.

its not that difficult. just get on the dyno. set your boost set up the fuel to it with a wideband o2 advance the timing until you start to knock then back it down a little bit and keep doing it over and over and over. see which configuration has the best results. richer more timing, leaner less timing, etc etc etc. spent 2 hours doing that wasnt to hard at all.

Mannys car is not running on an EMS, its running on a 2g MAF, and he won't program the EMS. Ignore him.

Y0. I have T-132 on my car and EMS and it spools by 4000 rpms. Shit is wicked kewl y0!

 

[anomalyinva]

That is insane. I know you aren't getting it anymore, but shit man. I don't think a 2.4L stroker motor with a built bottom end, 9:1 compression, race head, and a stand alone would be able to get that bad boy goin by 4krpm. As well, 16psi on a turbo like that would be so far out of its efficency range that you would probibly be slower than going with a 50 trim at 16psi.

 

[mclaren55]

Shit, if I had known tuning a car was that easy I would have done it from the start. Anyways, I have a GT35R and I get full boost by 5800rpm. This is on a 2.0L, 9:1, Haltech, and Marco tuning it. Sorry, there is no ####ing way you are getting full boost at 4k.

Anyways, who cares about "lag" either? I don't get any lag at the strip, cause i launch at 6500rpm's, and since its ball bearing I get killer transient response. As for lag on the street, who is going to ####ing race from a roll on in 5th at 60mph? Really, you downshift when you race, so lag is really a null issue nowadays.

 

[autronicDSM]

Eh?

 

[mclaren55]

I was responding to "TurboAWD92GSX" and his spool time claims. As well as everyone bitching about lag. When is lag a real issue? Never, under normal use you usual aren't in boost anyways. When you do get in boost, you are usually driving quickly or racing, in which case you drop a gear to get in the power band. No one is going to start a race at 2000-4000rpm, that's just stupid. So why does everyone complain about lag?

 

[bigfoot]

Lag is what I get when I tell the old lady a joke. He who laughs last, is stupid. Not everyone is a drag racer, there is this tight, twisty, brake pad overheating backroad that I love. Sometimes the RPMs fall a bit on some of those turns and a fast spooling turbo helps me control the car with power when downshifting isnt an option. But yeah most of the time it's the newbs that talk about lag all the time.
