Greddy T517Z/T518Z or HKS GT-RS turbo - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

blownmotor · 03-03-2007, 09:56 PM

I am trying to decide on which turbo to get for my SR my current one is shot so if I'm going to replace it why not upgrade. So my dilemma is which turbo Greddy T517Z/T518Z or HKS GT-RS ? Has anyone heard anything about Greddy turbos or own one ? Cause I know HKS uses Garett units and Garetts are pretty reliable. thanks

Dousan_PG · 03-03-2007, 10:56 PM

wha tkind of power you want?
those turbos are of all different power levels
personally i wouldnt get either.
but ive got my eye set on a 3071R at the moment

ronmcdon · 03-04-2007, 01:41 AM

just get a 2871r and call it a day. its essentially the same as the gt-rs.

viscid240 · 03-04-2007, 06:41 PM

Well it would be nice to know what you want out of the turbo/setup to better give us an idea for suggestions. Nice turbo there dousan 3071r is a great turbo but, you already knew that.

If looking for stock flange setup, which sounds like it to me. Go with what is proven and suggested by ronmcdon 2871r (gt-rs) but leaves you wth money to spare for other important parts as well.

Myself am looking or am planning on the 3076r with every supporting mod for my setup. Like I said help us help you, give us more of an idea on what you expect out of your turbo and driving style. There are lots of other turbos out there for cheaper and reliable as well. Don't go after big JDM company names when you can save with companies like Garret and such.

blownmotor · 03-04-2007, 09:42 PM

well im looking to make 350 at the wheels on pump gas

ronmcdon · 03-05-2007, 01:38 AM

well then the 2871r will do a good job of getting you there. go to the search function and input "2871r". check out the respective setups and dynos.

s13monkey · 03-05-2007, 03:45 AM

the t518z with a hks actulator would make your goal maybe more with some tuning, z32 mafs, and 770cc injectors.

maybe on race gas but not on pump gas...

sorry man wont happen.

The 3071R will get you 350 whp on pump gas.

around 400+ on Race Gas.

Its all dependent on tuning and supporting modifications of course.

yeah, i think you would need cams, a better turbo manifold and some good tuning for sure to get to 350whp. just slapping on 2871r isn't going to get you optimal results. there have even been ppl claiming over 400whp with 93oct pump gas!

here's a fun thread with dynos and such;
http://www.zilvia.net/f/showthread.p...ighlight=2871r

personally i hope to get a 2871, .64 myself, w/
-good bottom mount manifold (need to keep it subtle since in CA)
-mild tomei poncams
-740cc injectors
-larger z32 maf
-standalone MAP based ecu & dyno tuning
-maybe do a p&p along with a greddy im.

steve shadows · 03-05-2007, 03:36 PM

depends on dynometer brand, type of load and also whether or not its corrected, a lot of people leave this out so they can be like the magazine cars in superstreet with the magic 400 hp levels.

you can deff get 400whp witht he 28171R... even the .64 a/r...

don't believe.. check it...

steve shadows · 03-05-2007, 04:06 PM

sorry to re-iterate...

91 octane? without water/alchohal injection or race gas mix, It will not happen, or if it does happen it will not be very reliable in the long term.

I didnt mean to speak in absolutes, but I am perfectly aware and know all about the link your just posted from "NICO"

The guy also freqeunts Freshalloy and is the only one to have done it so far, and on the FA thread we never got an answer about whether or not the dyno was corrected or not in the numbers-iirc on that specific thread. That can throw off the rating by up to 35whp!

Go .86 ar 2871R and go external or go 3071R and external and start from the beginning with potential. There is a thread right now on FA that is turning heads in reference to the potentials of the .78 AR Twin Scroll 3071R.

Your just not going to get the torque and low end efficency with such a SMALL housing (i know in backyard b16 lingo bigger housing is supposed to be less low end right haha).

check it out.

that's a very informative thread! I'm really impressed with the 3071 twin scroll w/ full-race twin scroll manifold combo.

Dousan_PG · 03-05-2007, 05:00 PM

who the fuck runs 91?
even in CA ill go buy 100 at least
at the track, 110

fuck 91.
california sucks
i wouldnt daily such
pump gas back east/florida etc...at least 93. even that is meh..100 at least imo.

ronmcdon · 03-05-2007, 05:33 PM

there's no question 91 is shitty and that CA sucks, but running 100-oct is really inconvenient.
buying some 55-gal drum of 100oct to put in the garage, and then loading up multiple gallons for a track event isn't exactly practicle at least for me.
A lot of tracks like streets of willow and spring mtn. in NV don't even have the 100-octane pumps. I know the benefits of running race gas is an enormous performance gain, but I'd rather settle for less given the trouble.

I'd suppose octane booster may be a viable alternative, but i'm really skeptical of that.

Brian · 03-05-2007, 05:41 PM

Willow sure as hell has pump race gas.

is it somewhere around the main track? i've never seen it at streets of willow, and i've been there a dozen times or so. i've also been to the main track 2-3 times. maybe i wasn't looking at the right place.

codyace · 03-05-2007, 07:01 PM

400 whp, 2871r .64, JWT program for 91 octane (I run PA 93 tho)...

I can provide run files too

I am NOT running my meth injection at the moment (to lazy to datalog and send it back to JWT for the program in)...I DO NOT run 20 psi on the roadcourse, but I DO run 16 psi (which would be at the 350 hp range). On the street I do run 20 psi...however only a fool would run 20 psi on East Coast 90 degree/100 percent humidity days...

I am the only known setup doing this, and am the only known setup running my exact bit of parts. Did the extrude hone get me to these levels? Probably...but I think alot of credit should goto JWT as well for this...Clark is genious.

That run there is uncorrected, however:

Run 1:
SAE: 398.55whp 330.98ft lbs
UnCorrected:408.82whp 339.51ft lbs
DIN: 411.03whp 341.34ft lbs
EEC: 398.40whp 330.85
STD: 409.49whp 340.06ft lbs
JIS: 399.92whp 331.87ft lbs

Run 2
SAE: 400.65whp 326.62ft lbs
UnCorrected: 409.15whp 333.56ft lbs
DIN: 412.66whp 336.41ft lbs
EEC: 400.52whp 326.52 ft lbs
STD: 411.36whp 335.36 ft lbs
JIS: 401.75whp 327.52 ft lbs

codyace · 03-05-2007, 07:04 PM

And for kicks, here is my buddies Sentra (Stock USDM bottom end)...MSD 50 lbs, 28RS, Cobra MAF, JWT tune...at 17+/- 1 psi

and an overlay:

friend has a fuly built motor from dent sport with 272 cams 8.5:1 compression greedy intake mani 740cc injectors and we made a top mount manifold for the t517z n got a tune from enthalpy car made 270whp 20psi.

Nope, just a plain jane S13 Redtop that I got from Heavy Throttle last year...

The only thing I did to it internally, was install a set of S3 JWT cams....I did tear the entier bottom end apart (for my inspection) and put new bearings in her, as well as took the rings off the pistons, cleaned out the ring lands, and put the rings back in (I checked tolerances of course first, and everything was koesher...I know I know I know everyone should just re ring them, but I was anxious, and I wanted it to run ASAP lol.

usdm180sx · 03-06-2007, 08:44 AM

I have the gtrs w/ greddy intake manifold, step 1 256/264 cams, 70mm throttle body, fmic. At 16.9lbs it put down 341whp.

A friend of mine has the 2871r w/ step 1 256/256 cams, fmic, enthalpy tune and safc. His put down 330 at 19-20lbs?

Response and top end is pretty insane on both setups. iirc the 517/518z is very similar except that it's made by mitsubishi and the gtrs is made by garrett. garrett is ball bearing and mitsubishi is not for whatever it's worth. Just get the gtrs style 2871r with the .64. It's cheaper than both, does the same thing and bolts right on.
