Which would you guys go with?

My goals are pretty simple:
-"Daily driveability" with boost turned down so I'm pushing 400-450whp
-When feeling saucy, unleash more boost to get 600+whp
-Overbuild the engine/components to support 800-1000whp for better reliability now and future expansion "down the road"

Although I initially wanted the Greddy 20G tuner kit, I'm now heavily leaning toward the APS Extreme since it contains a complete fuel system upgrade to support my goals above.

 

the APS kit used to be a significantly better kit than the greddy, but frankly because aps now uses cheap chinese turbo's that are non-water cooled and non-true ball bearing, the greddy kit is far superior to the aps kit now.

I wouldn't suggest the Greddy kit either for you though, since 800-1000 whp really isn't attainable with that kit.

I would suggest since you are local, to AAM's custom twin turbo setup. They'll be easily able to upgrade turbo's and what not, with their own kit to meet you top end whp goals.

 

How about GTM's kits? They look easy to upgrade in stages when necessary and you can get all the parts you need right now

 

turbos are the biggest cost of the kits. a pair of new turbos will run ya another 4g's. Its crazy to buy a kit now with plans of upgrading it later. do it right the 1st time!

 

That's odd. I've heard the APS turbos are good quality. Here's a snippet from 350zmod.com...

"Twin GT30 Series Garrett dual ball bearing turbos (capable of 500hp each!!!)"

It says right there "ball bearing turbos", and from what I've heard the Garrett GT30's are outstanding. Again, I've not done a ton of research but what I've done so far indicates these are of good quality. Please tell me if I'm being misled here...

Thanks,

only the tuner kit and regular kit uses the cheap turbos. the OP is asking bout the extreme kit which still uses Garrett turbos

OP, I would def check out the GTM TT kit. its an amazing kit and very easy to upgrade down the line. Also very competitive as far as pricing compared to GReddy or APS

 

Since when did APS change turbos?

The APS kit has a lot more than the Greddy out of the box but it also costs a lot more.
You can put together a system with the Greddy for 700-800whp no problem.

 

no problem for 7-800 on a greddy kit

not sure what dynos you've been looking at...

 

you can always switch out the turbos to upgrade.. i really don't like the look of APS.. to me look kinda cheap.. the Greddy has more of a ORAH to it..

 

I rather run any turbo kit that has Garrett turbos than a Greddy kit.

Garrett=Ball Bearing-Water Sleeved for longetivity and no need for turbo timer
Greddy=Journal Bearing-Non Water sleeved-need turbo timer

It's all about what application you are planning on using it for.

Street-Greddy will be fine
Road Course/Time Attack events and such-Garrett Turbo's will be your best

Personal choice I would go with one of the GTM TT Kits or APS Extreme

 

Wait are you referring to the old APS turbos or the newer ones they switched to?

 

I have a garret in my M3.. so its all good. i just choose Greddy cause to me it looks like a better system.

 

besides... im not a fan of the inturnal wastegate setup.. looks cheap.

 

APS Extreme is external wastegate
GTM Tuner Kit are external wastegates

 

You should see what the guys on my350z have to say about the Greddy.

Some say it looks like it was put together in high school shop class
