The car drives very OEM... Really no issues what so ever... I only beat the crap out it for two days, last week we had some pretty good weather and it was fine...

I took Adam from Z1auto for a spin, and the first thing out of his mouth "This is the way it should have come from the factory"

This is the first kit done by PM... They really took there time. It had a tiny oil leak... They took care of it right away... I've been looking for spots... None so far. It idles great, no smoking, no bogging or pinging... Very smooth. To say the least.

What's great about it similar to the APS (GT Series turbos) they scream! Sounds like a jet from the outside!

It's always boosting... In vacum it's pulling...

The kit is new there are only a hand or two hand full of JWT TT Z's on the road. This is why the kit is available from Performance Motorsport. PM and JWT are working together to get real world feedback from us.

PS did you get my e-mail?

 

Sounds exactly like the comments all three test drivers had when we tested the JWT and 5 other turbo kits (summer issue 05, Sport Z mag article). Our main points regarding the JWT TT kit were:

Kudos:
· Water-cooled, full ball-bearing turbochargers
· Has everything you’d expect from a factory turbocharger
· Benchmark drivability characteristics, with across-the-board horsepower and torque delivery
Bottom line: A Wolf in sheep’s clothing--this twin turbo is so well-executed it could pass for stock.

I am glad to see an owner reinforce SZM's observations. I am sure the owners of the Turbonetics, Air Power Systems, GReddy, Power Enterprise, and Speed Force Racing kits will find the "kudos" we stated regarding their kits were accurate as well.

 

Could't agree more Rob. The boost is there instantly. It's also dead quiet at idle but it absolutely SCREAMS when in boost!!

 

+1 Totally agree.

 

OMG, my car is exactly the same way, INSTANT boost, and screems under WOT. The power is amazing

 

I didn't find your comparison very useful, well - maybe the spec chart, but not the dyno's or other data.

If you really wanted to compare the kits, you should have at a bare minimum had all cars that were running at the recommended stock boost levels and without any installation problems or other issues...

From your recent posts on the forum, you certainly are a JWT Fan!

 

One kit, car, exhaust, tires, brakes etc... will always stand out when tests are being performed. Is that not the point of the tests? Maybe he personally liked the JWT kit for it's OEM qualities and maybe the GReddy kit for it's unique qualities. I don't see any bias in his posts. In fact he is always said all the kits have thier own unique qualities.

 

Yea I'm real happy with the setup... One of the key factors with this kit like the APS and the PE (if you run your own lines) Is that they are water cooled. I drove the car pretty hard on 55 degree day. Pulled the car over poped the hood and heat was like stock... Maybe the guys from VRT can attest to this...

I've been in a lot of cars with turbos, where heat was a serious issue... And it ends up like a sauna in the car... Even though we are adding two turbos to the coolant system the needle does not budge from it's prior location when it was N/A

 

I think they were tring to run all the cars @ or around 8PSI.... If I remember corectly the PE car was Flashed for 8 or 7.5... But he had just got the new cast manifolds and did not get a chance to retune or something.... So he was running @ 4psi... That was a shame...I'm sure the PE kit would have performed well...

 

I have a digital temp gauge right in front of me when I drive. My car consistantly runs at or around 190 degrees. Never goes above 210 and only gets that high if im in boost for a long period of time and sometimes if I'm stuck at allot of traffic lights. It always stops around 210 though. I think I've seen 212 once or twice. Weather out here is like 80-85 degrees.

 

That's great...

Are you using the stock radiator? I' might put in a NISMO thermostat...

 

No, I have an oversized Koyo. I'm going to put the Nismo thermostat in next week. Gotta get ready for summer at the track.

 

Nice; so It's good to know that the oversized koyo fits even with that cross pipe by the radiator....

I wish we had road courses by me the nearest one is 4 hours!

 

Yeah, 2 hours for us (California Speedway). Willow Springs is 3 hours. The radiator fits but you have to cut the top of your fan housing to make it work. It's a tight squeeze but works out fine. Unfortunately when Mark asked me to cut mine for him (I was trying to help on my install, so Mark would give me the grunt work like that so I couldn't f$@! anything up ... LOL), I didn't realize it was a part that would show so I kinda hacked it up a little . Easy fix though. I try not to touch anything on my car as I am not very mechanically inclined. I usually end up spending more if I try and do something myself!

 

I have the same skills you do, Thank god Performance Motorsport is 2 miles away!

 

HAhahaha...LMAO.........+1...........I agree............................

 

Do you mean your engine "BLEW UP" with the APS kit or the DEAL "BLEWUP" between PM and APS???Im confused...
Also I am curios why you called our shop last month to ask our opinion on which kit we were reccomending? 2+2 is starting to add up...Hmmm.

 

1. We asked the manufactures of the kits to run the kit stock however they are responsible for bring the car to the test. Any divation from that was their doing, not ours.

Yes, in a perfect world, we could buy 6 350Z's and install the kits to get the perfect test however that is a dream world. No magazine I know of, including the biggest car magazines there are, does anything more than we did which is basically test cars given to us. In fact, I think you will find that new cars tested in many mags such as Motor trend, C&D, R&T etc have performance levels that exceed what owners get (0-60 etc). A good example of that is a test on the M45 0-60). Call them ringers if you like. The big difference with SZM is we actually dyno the cars to a set standard thus you actually know what they pulled. Most of the above mags I just mentioned simply spit out exactly what the manufactures tell them using their specs without verification.

We will report exactly what happens in a test. If the car experiences problems for whatever reason, it is part of the data. The PE car reflected exactly what was going on with PE cars of that period. He changed out some parts because PE themselves came out with the new parts. You cant have it both ways, up to the minute reporting and cars that have been running for 6 months. We got a JWT car as soon as it was available. The TN car just got on the street itself. Readers got a look at the kits early in the form they were in. The TN car had some problems and the good part is readers got to see just how good TN's customers service was in fixing it a week after the test. TN has done that again and again since then and it is good for readers to see this in the article, knowing about their service.

2. I like all of the kits for different reasons. Those reasons are listed in the kudo's and write ups of the article.

3. I find it interesting that who and some others did not find the article up to what you hoped. It interesting that with the owners of the JWT kit and owners of other turbo kits, the pros and cons of what we wrote about on each are very close to what owners themselves say after owning those kits. Regardless if the JWT was running 6.8 or 7.8 boost levels, the charactor is the kit (or any kit) does not change.

 

I understand all of your excuses - still would have been nice to be comparing apples to apples on the dyno...

 

yeah a dyno comparo is no good between kits if some of them are Mangos and some of the are kiwis....just not a fair match up
