New Greddy T620Z??
 

T620Z

What's the word?? Any good? Worth the $$$

You need a built engine to get the full potential out of it.

Low end vs top end, take your pick:

I would probably wait for the garrett turbo upgrade before making a choice.

I'm going to go with the Ptuning turbo ... Been wanting to pull the trigger for some time but wanted to waive for greddy to make their v2 kit ... and this one doesn't seem like it's up to my expectations.

Is anyone running one of these?

Is there any flow or wheel trim info on this 620Z?

I've been running a PTUNING turbo for over 15k and put it through a PA winter. From my stand point PTUNING is a great turbo kit. Hasn't let me down yet. Still getting around 31 mpg when on travel days but only around 20 on back roads lol.

What's that have to do with Greddy...?

@rocketbunny86 is using it, maybe he can chime in.

Hopefully someone can, I haven't found anyone running it yet. Curious how it'd be on a low boost set up with the stock block. Keep it around that 280-320whp with room to grow into the deep 300's-low 400's. Or if I'm better off running the 518 and swap to the 620 or Garrett down the road after the motor is built.

I'm pretty happy with the T518Z. Greddy kit piping, Tomei overpipe, 3" exhaust. Using the Profec boost controller and gain at -7, I get a flat 0.65 bar boost all the way to redline, overboosts if gain is set any higher - I think there is a bit more headroom that can be used with the T518Z before it runs out of puff. Silvia guys run up around 1.4 bar on it. Have not wound up the boost much more yet - not sure that stock internals on our fuel would handle it.

KIT is Fuked
 

I am running this kit, It over boost like crazy on stock motor. When greddy did there RND for this kit they tested it on a built motor with 10:1 compression. I have to put the stock exhaust back on to stop it from boosting to up 20psi.:bonk:

You dont have a boost cut on your tune?

yea. but from what Greddy and my tuner tells me its a hardware problem and it cant be fixed with a tune.
there was 3 ways to fix the problem.
1) new Spings for the wastgate
2) external wastegate (not sure it will work)
3) or built motor.

the problem was the wasgate not open with the compression differents

I'd love to see more videos of this kit!

You're tag should be "I'd love to see more videos of this" haha

But I agree :D

I'm running t620z for 3k miles on stock motor, tuner has limited the boost to 10 psi through grimspeed EBCS, it perform well on mid range rpms but acceleration is not that much responsive on high rpms, anyone know how to fix this issue?

Just posted my setup in the dyno thread: http://www.ft86club.com/forums/showp...&postcount=129

Loving the kit so far, will probably go E85 next year.

Do you have any video of test run? And how it feel on high end rpms?

I should be able to show you a few test runs on e85 once I get motoeast's flexfuel installed.


Just broke the 10k miles boosted. Runs great. If I remember correctly, My dyno was at around 287 with 10 lbs of boost. Stock internals with a catless invidia n1 set up.

Here is the video Dynosty made:

The car pulls hard all the way to redline. That is probably the difference between the T518 and T620 kits; the T518 gets into boost sooner but the T620 kit has a bigger turbo so it gives a big kick once the RPMs are up. I have 255's in the rear and they can break loose at high RPMs in 1st and 2nd gear. Will likely go to 265's next year, especially before getting an E85 tune.

Your ride making good numbers👍🏼. Its right now on 93 octane?
The issue on my side is its goes awesome on 1st and 2nd gear till readline, but it feel slushing and laggy on higher gear on high rpms, as you said once boost come it should give big kick but its not happening on my ride, its feel amazing on 4000-5000rpms, after that its not that much responsive as it should be

You got your ride tuned from motoeast? And you got 287 whp on 93 ?

Yep, using 93 octane.

I am still getting used to the car but I'd say it pulls hard in 3rd and 4th gear when nearing redline.

I had everything done there. I got the turbo kit from them and the install and tune as well.


Mine would be a bit higher, but of course it's an AT. So I'm missing out a little bit of power.

mine starts the pull at around 4000-5000 in third. It feels REALLY nice.

My previous ride was a 2008 Evo X 5MT with a turboback exhaust and off-the-shelf "Stage 2" tune. The car ran 12.8 @108 with a 2.0 60ft.

I'd say the FR-S pulls a bit harder than the Evo. Assuming I can put the power on the ground I'm thinking a 12-second pass is possible. I hope to find out at the track in a month or two. :D

VIDEOS!!

thats the same thing I'm facing, there is something wrong which i have to find out, otherwise it should not act like this in 3rd and 4th gear.

still on AT u r getting good numbers :thumbsup:

I just got this kit. pushing 300 hp / 250 lb ft @ 12 PSI on 91 octane. Going flex fuel soon!!

I'm running greddy oil cooler, koyo radiator, mishimoto fans.
my coolant temps get up to 215F / Oil temps get up to 200F in 95 degrees weather driving in the city, and I'm not boosting hard.

What are normal coolant / oil temps?
