why would someone buy a PE turbo over a greddy TT besides the ball bearing turbo's. what makes one kit better than the other?

 

There's lots of reasons. Both have their positives and both have their negatives.

PE KIT:

- PE uses IHI Turbos
- Stainless manifolds as opposed to cast
- Internal WG as opposed to external - less plumbing, fewer problems
- Comes with APC IC
- Fuel pump with PE kit

THe biggest thing that I feel sets aside the PE kit is it requires ZERO TUNING out of the box. You can install it and drive away with it and not have to tune it. Most people still do, but find that VERy little, if any tuning is required.


Greddy Kit:

- External WG may be more beneficial for higher boost later on
- Less costly than PE
- Includes E-manage which can be used in future for larger power / you would have to buy a reflash or tuner for bigger power on PE kit
- No fuel pump, less work
- Overall less install time than PE kit

 

Good points. I disagree with the install time assessment however. The Greddy turbos/manifolds are much harder to install because the fit is tighter. The PE kit requires no ECU harness wiring.

If you've already done the Technosquare reflash (or plan to do so anyway to raise the rev limit and/or get the throttle body "fix") then PE reflash is only a small incremental expense. However, if you haven't done the TS reflash then it's a pretty steep price to pay to be able to boost above the stock PE setting of 4.35psi.

Greddy has good individual components. Turbos are strong and very capable. E-manage is a nice piece. As a "kit", however, on the 350z, it represents a hack job....random component thrown together with band-aids. The turbos are far too large for optimal spool up and efficiency for the specified boost range. Bypass valves have to purchased seperately as does a fuel pump. And you have to remove the front bumper to accomodate the poorly designed intercooler. This is all basically becuase Greddy doesn't use parts that are optimal for this engine. Instead, they use "off-the shelf" parts and try to configure it for the Z, using a little bit of tuning. Basically, as an out of the box kit, the Greddy plain sucks. However, if you want to build your motor, and run these turbos at 12-15 psi, do some custom fuel mapping and timing adjustments, and have the $10,000 on top of all that to build the rest of the car to cope with that much power, then the Greddy system does provide you with a good base of components.

 

Their is only 1 "KIT" that is worth it...

The APS kit APPEARS to be the best yet. Nobody in this country has actually driven it. Actually....I don't know of even people from Australia who have driven it outside of APS themselves. They have, however, done a fabulous marketing job for this product, getting us all to think it is the "be-all and end-all" for the Z aftermarket. What is an undeniable fact is the quality of the APS hardware, as well as the engineering for this application. They have the right resouces for a second-to-none fabrication process. Let's just hope the tuning can keep up with the hardware and the hype.

 

PE is way easier to install than the Greddy....it takes about hald the time.

One other correction....the PE kit does not come with a BOV either. And keep in mind the reason the PE doesnt need tuning is becuase the base kit boosts 4.4psi, and doesnt include a reflash. If you intend to boost more, you'll need a reflash for $300-$500 a pop. Other option is to put the eManage on the PE kit....

The one big drawback to the PE kit is the cast manifolds, where are very prone to cracking after some time. APS and Greddy went with cast, and I heard that PE is in the process of switching to cast manifolds.

I pretty much agree with everything else mentioned.

 

PE has an ARC intercooler not an APC intercooler *shudder*

 

So the PE kit doesnt come with any type of engine management out of the box? Is the factory computer that rich?

 

Its doesnt come with engine management standard. It does come with a fuel pump, raising rate FPR, and bigger 380cc PE injectors. These three things will richen up the fuel curve....at least enough for 4.4psi. More than that would require more IPW, and some timing retard of some kind.

 

Here some questions, please answer:
1) What power can produce each of them at the same psi?
2)Wich one tends to be better to handle high pres settings?
3)Is there any need in reflash the ECU when getting the HKS' F-conV pro and HKS' Electronic Boost Controller?
4)Can I use these HKS' instead of the e-manage?

THANKS

 

1. So far power at the same psi for most if not all the TT kit out are comparable to each other.

2. Both can handle high pressure, but the Greddy might have an edge on this.

3. Don't need reflash if you are going to use a full standalone like the HKS F-Con V Pro.

4. Yes you can use HKS instead of E-manage. Search for thread by phunk he has done wonders with the HKS so far.

On the side note:

The PE kit does have stainless manifold and I already know of a person that had it and cracked both driver and passenger manifold.

The PE is easier to install than the Greddy.

IMO if you plan to build up later, the Greddy is great and it does the job intended. Also there are is a great knowledge pool on the Greddy kit on this forum. However losing the front bumper reinforcement bar is a poor design.

edit: One more note: If you think about this the Greddy can be like a Tuner kit (not an end all solution) and the PE Kit providing a set and don't touch approach. The APS kit looks to be promosing but only will know more as people install them. I like the Garrett ball bearing which allows water cooling and oil cooling.

 

Thanks for your kind compliment and I really hope you guys enjoy the high level of both the engineering and performance of the APS TT system...............we have gone to extreme lengths to please you all.

I believe it's fair to say that APS has gained an advantage over our competitors as we've had the luxury of a longer time frame to develop and refine the APS TT package................I'm quietly confident that the APS product will measure up well against all of the hype.

By the way.......... there has been a good number of Americans, Europeans, and Australians (sworn to secrecy) who have road tested the APS 350 Z TT during the development phase................and I'm happy to say that all of the drivers enjoyed the drive and the Z car surived the tortute test.

Thanks

dont forget things can be overhyped. I mean that as a warning not as an assault, it seems like a great kit.
just remember the Technosquare ecu is a great product worth the money, but it got so much hype people were expecting it to transform the car and were dissapointed when it didnt.

 

Yeah I know what you mean and I take your comment seriously....................there's just so much product info to pass on to the guys.................I'm not wanting to create over the top hype............I'm simply attempting to ensure there's accurate technical info pertaining to the APS TT available to all forum members.

Thanks

greddy kit and IC take about 20 hours of time to install with all the wiring and what not.

 

Tell that to the jackasses who spent 2 weeks installing mine and still did a horrific job. Oh, and their 900hp RX-8 was on the cover of Modified. Go figure ?

 

Is this Acosta? If so, I haven't heard good things by consumers for their work. Especially in the RX-7 community..

 

Hey Guys

One other thing with PE vs Greddy is that PE's turbos ARE also water and oil cooled, in additon to being ball-bearing turbos (which was already mentioned i believe). The water plumbing is not supplied, however, so i will be buying this myself.

I wonder what kind of strain a plumbed water cooled system would put on the stock cooling system. I'd suggest an upgraded radiator and water pump before attempting that. The turbos center section is so incredibly hot...it would certainly increase coolant temps. I gues it could be partially offset by decreased oil temp.

Interesting concept.
