Everyone claims that APS TT kit for the 350Z is better then the PE kit. I do not wish to be the first custumer to have a specific kit installed by a given shop (let the practice on someone else first). This is the dilema I am having. The closest shop for me to get the APS kit done is about 3 hrs away in Connecticut (XX Tuning), they have done any kits before. The closest one to have the PE done is Performance Motorsports (half an hour away). So, here is my concern: do advantages of going with APS justify having to deal with a shop that is 150 miles away and having to drag the car over there every time there is a problem?
In either case I will be upgrading the engine internals down the line and trying to increase the boost to at least 12 psi.
Please tell me your opinions. Thank you all in advance.

 

The APS is a more complete kit, and you'll need to buy some additional parts for the PE kit for them to be compariable... It'll end up costing you the same amount of money in the end, and the quality of both turbos, intercoolers, etc are both top notch.

 

Manifold issues with the PE....they crack. That I think is the biggest issue with the PE. APS are cast like the Greddy. Going to higher boost levels with the ecu re-flash may be a problem too...not totally certain on that though.

 

PE kit now comes with cast manifold as well. But what additional part do you need to buy if you increase boost? Injectors and such?

 

Both PE and APS are great kits out on the markets right now and I don't think you will be disappointed with either of them. There is an article on the PE turbo kit on this month Turbo issue....you should check it out.

Let me know if you decided on the PE kit, I can get you a great deal on it.

I haven't read up much on the PE kit, but someone mentioned that the turbos were water cooled?

 

Yes they are.....and if they have corrected the manifold problem then the engine management is the only hurdle. I have seen no pics yet of the revamped PE manifolds...maybe they are buying them from Greddy or APS

 

I would say APS. Since PE doesn't include very good (IMO) engine management. I can see using a reflash for a single turbo kit where most won't go over 360-440rwhp...but a twin turbo kit capable of 600+rwhp...it just wasn't wise for PE to choose a reflash IMO.

Something to consider, Garrett GT series turbo's supposedly last a long time too...

What are your power goals? That would be a good question to be answered.

Also, what's your price limit?

 

Moved.

 

My power goals are to be competitive with the new Z06, Viper and Carrera Turbo (HP numbers are secondary as long as the car can perform). Am I in over my head?

 

No. With a built bottom end, a good fuel system, and a proper tune, you will make them your b1tch. You're looking at at least $12k in parts/labor though.

 

I believe that you will find XX tuning a very professional shop and well worth the drive to have the APS TT system installed, I've spoken with a number of customers who've had APS twin turbo conversions performed at XX tuning and their feedback has been very positive, XX tuning are highly regarded by APS.

I would have thought that this major decision on which product to purchase would be better made on the basis of product quality, completeness of the intercooled twin turbo system, and the engineering of the APS product.

I undestand that the distance you need to travel is a real consideration though surely getting the product installed and tuned thoroughly is ultimately far more important imho.

Here's a link to the APS TT system http://www.************************/350z/350z.htm hope you enjoy and let me know if you have any questions.

Thanks

Hey Guys

OK, I have PE myself, but I would still recommend APS. PE DID go with cast manifolds now, although I do not know how it affected the price. I am getting my stainless ones swapped out for the cast ones as we speak.

The completeness of the APS kit simply cannot be argued with. It is not only the EM, it's also the watercooling, correct fuel system, etc..

 

Any professional tuning shop that is experienced with the 350Z can do an install of the APS kit. It is slightly more complex but nothing a quality shop couldn't handle. You can buy the kit from any dealer and take it to the qualified shop that is closest to you for the installation.

 

Yes Gurgen did suggest the APS system about a month ago, when we were out at the Filming of "Street Fury" for Speed Vision.

It is good to know that PE will swap out the "Weld up's" for cast manifold's
That shows support for users of the PE system..


Cheers Amy -

 

Hey GurgenPB, is PE charging you anything to swap the manifolds?

The new 350z and G35 kits will now come with the cast manifolds and the last time I talked to them about the new manifolds the kit price with cast manifolds was supposed to be less. Manufacturing costs on the cast version is supposed to be lower.

 

On no my fried, they will NOT, they far from it (at least as far as my car is concerned). I have purchased these from them and swapping them out on my own.

 

Their prices are rediculous. They charge 1500 for a pair of cast manifolds if you can believe it! My pair was far lower, which I appreciate. But still, 1500 for a cast pair of manifolds!

 

I have the PE and have contacted them about this. They haven't offered to replace mine for free. Not yet anyway. I'm still waiting to hear back from them to know how much they want. If they quote me $1500 I'm going to laugh my *** off over the phone.

Steve, that IS what they are going to quote you if they quote you the retail price... It MAY be nice quality stuff, but heck, $1500 for cast anything isn't worth it... should be around $400...
