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
