Got you Gh8st! The PTP was the kit up your sleeve! I was trying to figure what you wanted. I will say I like the honesty of Tim from SPF about the dyno and drop off. I did a price check on the SPF website with a ball bearing and the works kit and it came out to 8K with everything. I will say that many of the Rx7 Guys have nice kits for half of what many ask us to pay. Since this kit has been out for sometime and now the new upgrades what do you say to giving us a better price on these kits? I mean the 350Z twin turbo kit you guys have is priced at 7.5K, wouldn't this kit have more parts and such? I think the kits that will separate themselves more distinctively would be a good quality kit and know how (like the SPF) with a more attainable price.

 

You can't compare turbo kits for stock turbo cars with stock NA cars. The level of design and required components are different. Now you could compare the components of the 350Z kit and the Rx8 kit, but $1000 is not that much. That could be entirely attributed to quantity of kits sold and a couple little things.

 

yeah. i really dont think the price is unreasonable. the greddy tops out at 290, and 270 for most people. so we need jeffs help to compare it to the sfr kit.

look at the greddy. lets make it new, so its apples to apples. thats $3500 at most places. then you need an accessport, $700. then you need a mm's upgrade, thats $1700+. thats ~$5900 and you are stuck with a crappy manifold that is prone to cracking.

the sfr has a base price of $5800.

i really cant see a point in complaining about price.

 

does the SFR kit come with an ECU? the PTP kit is $4900.. and there is no noticeable difference between the two. as far as i'm concerned, the PTP is better value for the money. but I'm seeing SFR making a big effort in improving their kit, where as PTP have stalled a bit..

 

hey, PTP doesn't come with the ECU with that price, that's what people always say tuner kit....SFR will offer lower price if you ask them for the Tuner kit, where it is only the turbo kit , without ECU, injectors and fuel pump. i believe SFR cost sround $5500 for the tuner kit....

check it again...you start with the best value, and you can always upgrade it toward your specs in the future....can't go to the sky immediately unless you are a rich guy...LOL....but you can start slowly...

yeah i know PTP doesn't come with the ECU, but neither does the SFR kit. What i'm saying is, if you want to get just the turbo kit with none of the upgrades, the PTP is 4900 and the SFR is 5500. so why the different? is it $600 better? Cuz i can use that money for apex seals or some extra gauges

 

The better service and communication from sfr is worth the extra $600 IMO compared to ptp. Read that thread I posted of wantedtwo's turbo build. You will see why he went with sfr over ptp.

 

What MazdaManac upgrade? That option is vaporware now.

The only solution is to send the stock turbo out to BNR for the upgrade. Then you need to buy the CobbAP, blow-off valve, AEM Cold Air Intake and GReddy Coupler Upgrade Kit.

Greddy RX-8 Turbo Kit - $3500
BNR Greddy Turbo Upgrade - $1050
GReddy Coupler Upgrade Kit - $270
Cobb AccessPort by MazdaManaic - $700
AEM Cold Air Intake - $315
Greddy Type RS BOV + adapter - 210

Total: $6045

I hear this kit will be available soon with all the components above already done for you so it will be a true bolt-on kit without having to mess around. The only downfall is the cast iron exhaust manifold is prone to cracking.

The only thing I hate about the SFR kit is the fact that I cannot use my OMP adapter and that means no more synthetic engine oil.

 

Well we try to do the best we can as far as customer service goes.And at the entry level price of $5500 for the tuner kit,it is not far off from PTP's price. And I am sure if you look at the list of components,you will see that some of the materials we use and components we chose for the kit are better.So you are paying for higher qaulity.That is where the extra $600 is coming from. But you know we could always use an Ebay wastegate,Ebay turbo and Ebay intercooler! Note: The Evo by-pass valve has been replaced with a Synapse unit!

what exactly makes the SFR a higher quality turbo kit than the PTP? from my research, i found that PTP uses the highest quality material. i even spoke to chris at esmeril and he told me the same thing.

 

When you look at the total cost of a turbo project, $600 isn't much at all. I don't know what PTP uses vs. SFR, but I don't think PTP has much of a forum presence. Customer service is criticial. Again, SFR and PTP could both be a pile of jerks or saints, I don't know, but when you have a car that won't idle because one of an umpteen vacuum lines is plumbed wrong, you'll be a much happier camper if you can get someone on the phone who is helpful.

I would recommend before you send anyone $5000 or $6000 that you list out exactly what you are getting and what the options are. Talk to each a couple times. Track down cars that run each. Write down what other things you will buy. What are your needs vs. your wants? You might find that for $6500 starting with the more expensive kit, you can get a ton of extra stuff that down the line would have cost $3000.

I'd say forum presence is a plus. Being willing to adapt a design to fit a Cobb AP (shows continuing product development) is a huge plus in my book. Lead time on a kit would be very important.

 

Chris has us do work for him and buys certain things from us for his turbo kit.But we also use 321SS for our headers,Spearco intercoolers,Turbonetics or Precision turbos,Tial wastegates,etc.............And our welding is second to none.

that's a good point maxx. I have done extensive research, compared countless options, upgrades.. i'm not trying to be cheap. i know that 600 isn't much, but I need a good reason to spend 600 more. SFR, giving you guys a call as we speak

 

just spoke with tim over the phone for about half an hour.. and he pretty much had an answer for everything. the kit seems very solid, the company seems very solid, and tim is very knowledgeable. great guy to talk to! i will be calling again with many more questions =)

 

I am still very interested in this kit but I don't have a clue what turbo would be the best choice. I would defnayely pay for the ball-bearing option.

I would think the T62 and T67 would take too long to spool.

 

t62 kicks in at around 4200rpm and the t67 around 5500rpm according to tim.. i would go with the 60-1 with the ball bearing upgrade as well.

 

Yeah, that spool is way too late.

Would there be a better turbo choice than the 60-1 though?

How would it compare to the GT3071R?

 

Anyone know if the AP map(s) are unlocked?

 

i'm still new to this.. but the GT3071R is a 60mm right? the 60-1 is essentially a 61mm, and according to Tim, garrett will not offer any kind of warranty on their snail, where as turbonetics offers a 1 year, no questions asked warranty. i think other than that, the performance is identical

 

Ok Tim since you brought up Chris's kit how would you say the PTP,SFR kits compare to his? Looking at all thats in the Esmeirl kit seems to be a good deal and we've seen dyno's of this thing pulling hard through redline. He also has the option for an upgraded turbo.

 

I really cant get into this kit vs. that kit because A. we work with Chris and B. it is not right to do that to another vendor on a public forum. But I will say that I believe the intake manifold is what is contributing to the car pulling till redline.A turbo is a turbo.If it can make and hold boost till redline then theroetically,it should make power up there.But there is some sort of limitation which prevents that.We might consider doing an intake manifold for this car if there was enough interest but I can tell you right now that it would be in excess of $1500 retail for a nice aluminum manifold with CNC'd flanges ,etc.........
How many people are willing to spend that kind of money? LOL

 

The thing is that the 3071 uses a T3 hotside and we are using T4 hotside. So it means that turbo will not bolt-up to our manifold and downpipe.We can adapt a
T4 hotside to that turbo but it wil be mismatched

 

Tim are your AP map(s) locked??

 

This is so true and I was holding back on that until mentioned ... Good call I would say another honest answer and in good tast! I think people would be interested and you guys have done this on other cars so I know it would be good. Lets say you do one just to see what it will do, you think it will show a 20..30...40..whp improvement with your kit? It should show an improvement with any kit right?

 

I would pay $1500 for an intake manifold but it would have to solve the high RPM issue and have a dyno before/after sheet to see the improvement.
