Well it depends what you want the kit for, and which JWT kit you are talking about the 530BB or 700BB?

The APS Standard kit will put out more power than the 530BB kit and I like the design and appearance better.

The 700BB kit is better and more comparable to the APS standard kit but the APS extreme kit blows that out of the water.

The APS TT seems to just be the best all around turbo kit regardless if you want to make 400rwhp on a stock block or 600 rwhp on a built block. It can do both

Thats why I favor the APS TT over the current kits on the market.

George...you have a PM!!!!

 

That and the fact that it comes with garrett ball bearing turbochargers. On a built motor I'd rather just go straight to the greddy kit as it comes set with external wastegates. I've seen what a PITA those APS internal gates can be at high boost and would rather do without.

As far as *high power* built applications, I'd still like to see the sound performance kit (if it ever makes it to production) before I decide which I think is "best". The APS Extreme kit looks really nice but I'd rather do without the APS fuel system.

From what I've heard that's an understatement... heh. As far as APS vs Greddy customer service, good luck getting help either way you go. I'd prefer to buy something built/produced here in the US by someone I can call up and talk to. That's why I kind of like the SP and SFR TT offerings.

 

+1

External wastegates on the GReddy kit is a very nice feature. This kit also has very good value for the price.

 

Looks like the PE kit is the crapkit of the TT's eh?

 

Yeah George... Since you guys have tuned all of the above, how about a dyno chart over laying all of the different dyno runs. It would be interesting what trade off there are for more peak power - ie, boost threshold vs higher HP...

Thanks.

 

The FMIC is really limiting on the PE kit.

 

I wouldn't call it craptastic, but in comparison to the GReddy and APS, the price for what you get in the end doesn't compare. Small turbos, small intercooler, small potential. It's a nice kit, but doesn't really put out the numbers very well in comparison to the competition...

FWIW - I've always been an APS fan. I went GReddy on my last build on account of the tuner/shop's recommendations. In hindsight - bad decision on my part. Not because there's anything wrong with the GReddy kit, but because APS quality is truely a notch above everybody else out there. And in regards to the boost control issues with the APS kits - it's all about the Forge actuator swap. People running these have had little to no issues with the APS kits since they came out. BUT I've also heard very good things about the JWT TT kit with the BB700 upgrade. If I was looking to build a solid 600whp daily driver, I might even consider going this route...

 

That wouldn't mean anything unless these kits are on identical cars with identical mods

 

I'm lovin my JWT TT

 

Oh, and I will elaborate: I'm very happy with my JWT w/530's because they spool instantly, which is what I was looking for. I may look to build my engine eventually, but for the foreseeable future, a quick spooling, low boost kit is exactly what I wanted. The 530's are good for up to about 14 psi, which is much more than a stock engine can handle on a daily basis, and still pretty good pressure for a built engine. I have full spool by 2.5k rpms, and max torque is not long after. It's perfect for what *I* wanted. Other kits offer other attributes for other expectations.

 

This is a perfect example of why there is no "best" kit, it really matters on what the end user wants. In this situation the JWT 530BB kit was the "best" for Dave, what is the "best" for you could be totally different.

Thanks for your input Dave!

I like the JWT TT set-up. What down sides have you seen??

 

your sig says you have a built greddy TT ... how come you're asking?

 

****, I thought the APS xtreme had external wastegates. I wondered what fuel management/ tunig are people going with on the APS extreme, and on the Greddy are most of you sticking with emanage?

 

Aps tt > all other turbo kits imo .

 

pretty good answers guys.........i would have to say, i like my greddy kit, it does have a few issues that are annoying but i think all the kits have small things that are annoying, plus other kits are way more expensive................so i guess for me Greddy TT for the win!!!

 

I just thought that it would be a nice discussion........just to see how many people were like APS all the way or Greddy etc......plus i wanted to see if anybody regreted the kit they bought for their car

 

No i upgraded to the Ulitmate and got all the bells and whistles for it..

 

OP..... How is your car built?? what internals??
