APS TT, Greddy TT thoughts
It is my understanding that the APS TT kits provide a very clean install and everything fits better than with the Greddy kits. I originally was going to go with APS, but switched to Greddy when I decided that I wanted to go for more power. Nonetheless, if I were looking for the hp numbers that you are looking for, I would go with APS.
I admit even going over Youtube the Greddys seem to dominate the videos with a few rolling videos of APS twins on a Z, there isn't many videos of it performing at the track or otherwise. The videos of Alberto's Z tearing it up to 170 comes to mind, but I think the highest boost APS video I've seen is a short outside burst from maximumsportz.
However, there are better options out there for fuel system and EMS now, so if I were to pick APS, I'd pick the tuner kit and get the other pieces independently (CJM RFS and Haltech).
I've only heard a couple instances with the cracked Greddy manifold also - if I were installing a new kit today, I'd reference those posts and get that spot reinforced since it was in the exact same location in the reports. Alternatively, engine dampener, thermal coating inside and out and using flex sections on the exhaust might help relieve stress on that part.
As others have said, both are decent kits, with a proven track record.
EDIT: forgot to add that I think a few have managed to install the Greddy intercooler AND KEEP the crash bar. Quadcam?

If I remember the correctly the power delivery was smoother, the idle, and the overall drivability of the car sounded to be much more appropriate.
Excellent and very fair post.
Like the others said, both kits are good kits with a proven record in the community. I don't think you could go wrong with choosing either one.
Another aesthetic consideration (if it's important to you)... Do you prefer the look of a horizontal flowing intercooler core (Greddy) or vertical flowing intercooler core (APS)?

Now I'm just racking my brain trying to figure out what seems to be more worth it, it seems to be - Fit and Finish vs Overall better performance.
When it comes to the intercoolers to be honest the flow type doesn't bother me much either way, in fact if I could somehow powder coat or paint them I would just so it doesn't pop out in a big way. I'm a big fan of factory turbo cars covering up their intercoolers for the most part.
I don't know why but I'd rather have something that didn't attract too much attention till the hammer falls.
I did not install my TT kit, but I can tell you I havent heard of either the Greddy or APS having fitment issues. Every kit has the ability to not fit depends on who is doing the install. If you want open dumps the choice is clear. If you want slightly quicker spool again easy choice.
Oro, it seems to me you are looking to hard into this. If I did do the APS, Id go with rcdash's advice and get the tuner kit, with a Haltech and RFS. Honestly flip a coin...
From what Ive seen up to about 10-11psi they make the same power (stock block) past that the Greddy starts to make more power per psi, but I know the APS can get you to mid 600's, anyone remember Bigbri?? He had claimed 730whp on a crack ***** Dynomite POS dyno, but he trapped 135mph, thats 650whp range easy....

Thanks for the help Alberto and everyone else who posted, I appreciate it.
i think the loss of the bumper brace with the greddy would make aps my obvious decision. i see way too many low speed fender bendes every day and was in one last year. That woulda been enough to crush my IC, rad, for sure
but in terms of performance, have fun!!

Hey guys, I am currently N/A and have finally decided to pull the trigger on a TT Kit after looking at my options. I've narrowed it down to the APS and the Greddy TT kits.
My question to those of you who have the kits, what would you say the ups and downsides are to the respective kits? (I have searched and found a lot of reviews from people who are happy with their setups)
What I'm looking more into is I see a ton of people on the boards running the Greddy TT's with massive amounts of power, yet I hear APS turbos running out of breath near 500 and others saying it can pass 600 fairly easily?
I have access to both kits at the same respective price and am having a tough time trying to pull fact from fiction or just brand favor out of the picture and finally make the decision as I'm not partial to either particular kit just that I know I want it to be either of the two.
I'm not looking for anything wild, 400's I would be happy with, looking more for longevity and reliability then all out maxing out of power. Anyway if you guys could give me some insight to help me out, I would appreciate it greatly.

Werd! another twin kit using Garret's.. Nice very very nice..
For what the OP is looking for and a stock engine, I would recommend our Stage 1 Kit GT28RS .64 A/R . The biggest advantage that we have over any other kit on the market is the ability to upgrade from our Stage 1 Kit to our Stage 4 Kit (1000 hp ) without having to reinvest in another turbo kit. Of course you will have to change the turbos but every thing you see in that picture will work from Stage 1 to Stage 4.
We also included a large intercooler from the beginning, not to mention, we offer larger piping than any other turbo kits available on the market today.
I think for a price tag in the $7K range for a complete kit with which will include a true garret ball bearing turbos, engine management, fuel system and the ability to upgrade makes our kit superior to any other kits in the market.
PS - A full press release should happened in the next few days.

Keywords being Garret, Engine management and fuel system ... Those three are very important. This kit already looks less expensive than a Greddy kit with IMO better turbos (turbos maybe more expensive to rebuild if ish hits the fan but whatever). Also IMO looks like good competition for the plab single kit which seems to be doing ok. Can't wait for Video's and testimonials. Looks very interesting.
negative HW....its a nice quality kit; but single kits are different than a twin turbo kit, you cant really compare. YEs garrett better turbos, but one thing you must have learned by now from reading the boards is NOT to underestimate the greddy kit even with the old turbos.
BTW the 1000 hp is that based on "math" from using the bigger ar on the gt30s?

Personally, im saving up for a APS TT tuner kit. One thing that draws me back from the greddy is the banktrupcy issue and the fact that you can really choose what you want and dont want. And just a tad pricier too. Im lookin for 550whp on my z so i think APS will do fine with me.

quick question? Did u happen to have twins and swapped to a single or anyone on the boards for that matter? I'm all over the place as to which may fit my goals.. I personally want something that will spool up fast as opposed to higher up in the RPM range. thx in advance guys...
