I am not so much concerned with the physical turbo install or IC. I am more interested in the programming, tuning...

Becuase of the emanage for the Greddy is the tuning more difficult? In the end, does buying the PE make it about the same price to get 400 rwhp?

 

Ahh come on...

 

PE kit itself uses great parts. Uses nie BB IHI turbo and nice looking SS manifold. But when you making a purchase, not just what you are buying. It's all about who you are buying it from and how you will be treated.

But just my out look on this kit. It's a more expensive kit. Even the retail prices look similar on the paper. But Greddy kit you can purchase thru their dealer. (ME) for far less. The PE kit you can't even get a break off the MSRP.

The Greddy kit come a lot closer and easier in getting the product vs. the PE kit. Their stocking is unbelieveable slow vs. the Greddy kit. To my knowledge, they can only get like a shipment every 2-3 months. And only 5 kits per shipment.

Also consider for a 30-40 hour kit, this kit don't come with instructions. For this much investment, would you like less headache? Also Greddy offer a better customer support. All of their tech dept. and sales dept. speak fluent English.

Also warranty. Which is another espect you want to consider. Which it would help since when things go wrong, we rather need a shoulder to cry on or a direct to throw the blame on.

So here's all of the lay outs when you are thinking about purchasing your kit. Not to mention you need to purchase/tune your own fuel management unit.

 

So, the PE kit has better overall hardware, you need to get your own software and it takes longer to install? I thought PE's was easier to install because of the electronics. I am still undecided on SC and TC and can't commit to any brand - too many options (though this is good)! I'm also concerned that the prices will drop drastically in a few months, which will let me upgrade.

 

Not neccessarily better choices. That's a judgement call and very debatable. But good parts just like Greddy parts. Some people say BB IHI turbo are great. Then again, Greddy's Mitsu turbos are known to be reliable and have a huge shaft that make it spool quick.

The price WILL not change drastically. A lot of greddy kits are sold on this site damn near whole sale prices. Greddy put a lot of R&D into this kit. You will know if you seen or install one. Everything is very tight. And example, Greddy's single turbo kit for the supra have been the same MSRP since it came out 7-9 years ago.

We have done both the Greddy TT kit and Vortech kit. Choose wisely, listen to people's experiences. Not online hype.

Like I said, I'm very happy with the Greddy TT result and the Vortech SC result. But then again, I"m a vendor and I'm biased.

Let's get Cheb in here and since him and BBB are the only members with the PE kit. See what he says.

 

Hallo-sorry for the delay in reply-

okie dokie. here are some observable differences in the installation i've seen between kits

Greddy's twin setup for piping is overall similar to PE's. greddy has two individual turbo outlet pipes that converge at the intercooler. you might have noticed that the greddy IC has two inlets on the left side and one outlet, on the lower right. piping then routes around the front frame work and up and over to the throttle body. imho, this is alot of bent piping , and the straighter the path to the TB, the better...

PE's turbo outlet pipes converge just prior to the IC, so that the intercooler has one inlet and one outlet, but on opposite sides.
Injet is on the bottom left, outlet is top right. if you've seen how the Injen intake pipe runs through that hole in the fender? well this is how PE pipes the air up and to the MAF and eventually the throttle body. the production piping goes up and into the front fender hole from the IC, and makes a bend to the Maf, and after the maf, a straight shot to the TB. this was changed from the prototype version, and ithink its stupid. so i might make my own pipe from the IC to the TB here...

injector install is the same for both PE and Greddy's kit. PE comes its own fuel pressure regulator that replaces the factory one. i think the emanage controls the fuel.

electronics: Greddy's Emanage kit will have to be spliced into the car's ecu harness if i recall correctly. which adds some time here. bad splices and your car might have problems.. professional install is recommended. i.e. soldering the wires then using heat shrink, none of this clip on stuff.. then you got your boost controller to run the wiring for.

for PE, if you want higher boost, you'll have to install a boost controller. for engine management, the kit runs fine out of the box, but again, thats only at 4.4psi. if you want to go higher boost, then you have the option of going with an aftermarket piggy back, such as the emanage, or have your ECU reflashed, which i did from TechnoSquare... reflash controls timing, a/f, etc. technos can do custom maps for the car, which is similar to the emange, which you do that with a laptop (ask jeff)

the main difference is the engine management really. so your install will vary from there on.

in all honesty, the only reason why i went PE was because they prototyped it on my car. i wanted what i was involved in. i drove it during the pre-production and it was bad ***.. i bet if i drove the greddy or had the opportunity to do another system, i would probably want that one. so really.. quality wise, i'm sure greddy and PE parts are both very good, its just a matter of choice.

PE told me that they were aiming for a niche market, not really going after Greddy TT customers. so maybe thats why their customer service is lacking and yes. its true, the kit comes with no instructions. but its not as electronically instense as greddy's is. the PE kit is pretty much a bolt on in stock boost form.

i'm not quite sure about the greddy, but with the PE1420 turbos, i got full boost somewhere in the range of 2600-2800 rpms. it spools really fast. and its really enough to make anyone happy.

hope i didnt bore you with the nit picks. but that's the low down on my side... if i left out anything on the greddy Jeff, please correct...

i would like to drive a greddy TT and compare, and i know that will be coming up soon

 

at the 4.4 psi, what numbers is the PE putting out?

 

errr... stock 0.3bar boost power, i remember correctly was around 350PS, we did it on the bosch dyno... 0.5bar got us around 380PS, all mediocre tuned. i.e. not optimised and A/F was rich with timing was retarded to be on the safe side..

i would expect 400 easy with a correct tune on the ecu for anything over 7psi.

 

Hmm...so about equal (a tad greater I believe) to the GReddy?

 

yea. about the same as the stock greddy kit--

hey Jpizzle-

here you go:

 

oh daym man, that's sexy, thanks

 

redoit. i made the door go up higher..

 

Hi, I would like to know is it require to remove the front protected bar from installing the Greddy Intercooler?And If I install the intercooler does it means I cant have the Protected bar anymore?
By the way, is the wastegate usefull in in 350hps Z? If not then I am planning to get PE t/t kit.

Which T/T will you guys choose interms of performance, best T/T kit parts, and reliable T/T kit?

Thank you..

I think the JWT TT might be worth the wait........I am

 

The front bumper brace is permanently removed. That is the one significant drawback of the Greddy kit...for the safety minded. The PE kit uses internal wastegates and slighly more compact turbos. The greddy uses an external wastegate. This makes installation of the Greddy a major PITA. There is almost no room to spare, which is likely the reason that PE went with internal wastgates. External waste gates...all things being equal...tend to hold boost better, and are less prone to boost creep.

Both kits are very reliable, and can generate more power than you'd know what to do with. It really comes down to personal preference. From what I understand, the price of the PE kit has come down to within $800 of the Greddy kit...which makes it a great alternative, at a comparable price.

One thing that may help you decide. The PE kit is great out of the box, or with an ECU reflash, you can boost even more. But it lacks on the fly tuning options. You'd need a reflash everytime you decide to change the boost. For many people, this is not a problem, since 90% of the users will likely set boost once and forget it. But if you are more of the "tuner" type, and wanna play around with different boost/fuel/timing settings, than either get the Greddy...which includes the eManage...or buy the PE kit, and then buy the eManage aftermarket for about $300.
