Hello
I know this is my first post and that I am new to the 350z forums.
But I am not new to the sports car forums. I have owned and do own many exotic and daliy driver dream machines and understand the need for higher performance.
Now to get to the point

I have just got into the zz world and I am unhappy with my new track model. very under powered .
A good friend of mine owns a fabrication company and is now in the process of making a customized turbo kit for my new 350z now . I have been reading alot of the post on the forums and it seems alot of you are waiting for a new product that will make your zzs a streetable monster without giving up any reliablity.

I have a couple of questions for you . It would really be helpful in me making my decision to mass produce my customized kit.

1. what type of realistic numbers would you guys be happy with?
2. what type of money would you be willing to pay for a reliable kit that produces lets say 250 more rear wheel hp
3. would this be too much rear wheel hp or too little to make a large investment?
4. what kind of interest is there?
5.what would or wouldnt you be willing to lose.
example( different hood,sways,etc...)

I have done many custom turbo kits from 200-1000 additonal hp on various cars, and my friends shop has alot of experiance.

Now The kit that is being built for my car is totally custom and is going to cost more than most people would be willing to pay but that is the price of making more power .
I would really appreciate any and all responses.. these answers will really help make my decission to make or not make a mass kit that will make alot of 350z owners very very happy..
thanks

I'd like to see a kit that does low 12's in the quarter mile, and is safe enough for everyday driving, for under 5gs.

If you're going to make a turbo kit you'd best get a move on with it. They're are like 3 or 4 companys coming out with them within the next few months. The plus they have is that they've been testing them for months now. But if you want to dive in and make one. Low 12's sound good and under $5K sounds better. Oh, It's very important that my engine dosn't BLOW!

 

im with him and for number 6 i woundnt want to give up a hood or any thing like that and if it was making a extra 250hp at the wheel that would be great .

 

I'd pay 3 grand for a custom turbo kit that outputs 100+ RWHP.

 

1. I'd be happy with low 12's, probably around 400 rwhp.

2. I'd be willing to pay 10g's for a kit that kit produce 250 extra rwhp...that said, without changing internals, I don't think it will happen, but who knows.

3. Too much or too little...I guess it all depends on whether or not it's a safe investment or not. I don't want to pay for 250 extra rwhp if it's gonna break my engine. On the other hand, I don't want to pay 8g's for a kit that produces 60 rwhp, unless it's easily tuneable (meaning I don't have to buy anymore parts) to more than that, ie. kit comes with decent sized turbo that's just boosted low to allow the consumer to up boost and hp at own risk.

4. Seems like there's alot of interest on this site. But I'll be the first to say that you are not the first individual that has come on this site and said they were making a turbo kit for our car. I have seen quite a few actually, and they've all just kind of faded away.

5. I would like to be able to keep everything the same if it's at possible. If anything needs to be changed, it should come with the kit, ie. stillen supercharger...you have to buy the hood with the kit...kit should come with the hood. Oh and, I would like to keep the internals stock for now.

 

10 grand for a turbo ? What a waste.

 

Yeah, I wouldn't go there either. Anything over $5,000 might be a waste.

 

May I ask if you were planning on a single or twin turbo set up?
<$6k for a single turbo sounds good to me

 

Vishnu performance makes a kit for the WRX which puts it in the low 12s for 5 grand. But it comes with a full turbo back exhaust system. So, it's quite a nice deal. I'd be very interested in something like that. I need my car to be reliable enough to be driven 30-40 miles a day, and i don't believe that any car can reliably run lower than 12s in the quarter mile and still do that.

 

the rex is also a turbo car, so it's a lot cheaper to get that power. plus awd always helps w/ getting into the 12's.

 

My Single Turbo Supra had closer to 600HP (capable of 10's) but I would be happy with 400 rwhp on this car. That means I would need an additional 150 rwhp. It also sounds like $5K is the magic number. That will be a tough price to work with. Turbo(s), IC, ecu/fuel management system, gauges, downpipe, etc. I think $7K without installation is more realistic.

Personally, I would not be interested in anything that required additional paint (IE hood). I have seen to many Z's that have body kits that don't match, colorwise. The front strut bar isn't a big deal but if I could keep it I would.

My guess is that with 400rwhp a well driven Z may make it into the high 11's/ low 12's depending on tires.

I would definitly buy at $7K if it had a nice warrenty and included installation.

 

Yeah, I'd be happy with 400rwhp, but I'd pay 10g's for a kit that produced 500 rwhp, or about 575 hp at the crank, which would be the extra 250 hp speed101 referred. Of course, I would expect that kit to come with low compression-pistons, forged steel rods, etc, etc., not to mention, top of the line ceramic ball-bearing turbos, giant FMIC, decent sized internal/external wastegate, top of the line BOVs, quality eletronic boost controller, bigger fuel-injectors, bigger fuel pump, top of the line stand-alone engine/fuel manangement system, all piping, manifold (if needed) with egt mounted, and all gauges and monitoring equipment. Add all this up plus R&D. I'd pay 10g's for 500 to the ground. That would make my car cost considerably less than a vette, but be considerably faster .

 

I would scrounge, beg, steal for a turbo kit that gave me 350 rwhp for $4000 plus installation. Im not greedy. Id like a good platform for further modding, reliability, driveability.. and results at the track and strip. Single or twin.. dont mind a lil lag as long as the copious stock torque down low remains. Maybe this is too much to ask but hey Nissan made the Z accesible and the Z is a success.

 

-Low to Mid 12's
-Entire Set up less than 5k
-Daily Driver Safe
-Warrenty on the kit just so we feel safer
-No design sacrafices

The Z06 does a 12.8 in the quater mile (according to Road n Track), and I believe thats 405hp, so about 18% loss, your talking about 335rwhp. If you can make about 100-125rwhp gain, on stock internals, and daily driver safe, you would have a LOT of interested people.

 

Not asking for very much are you?

Personally, I think a single ball bearing turbo would be the answer. That would save cost on twin everything, and simplify plumbing. I can't see why you would need a new hood or have to lose the FSTB. Keep it under 6k, and keep it simple. If there was an option for $7500 with low comp forged pistons, and rods, that would be sweet too. An extra 250rwhp, on stock internals with reliablity most likely isn't going to happen though. Other cars that have been able to achieve that were factory turbo (lower CR).

 

Yeah, this will probably never happen. It's just that it's rare to see a COMPLETE kit...one that comes with everything you need.

I'll even do a swap with you.

One customized turbo for my 350Z in exchange for a 3-4 page feature article in Sport Z Magazine. Your photos included. Plus, one year [4 issues] of a 1/2 page ad featuring your company and your product. Heck, we'll even do the graphic design for you if you wish.
