Due to this kit being manufactured here in Canada, it will have some detractors. Availability will be limited due to single person shop... however... quality control is thru the roof and exclusivity is part of the reason we customize our cars. You don't want a kit sold at Walmart, do you?

When Sasha gets up to full production on these kits, there will be some very happy boosted customers all over North America and a user installable, friendly, reliable, powerful option for single turbo customers... Choice is great!

SS_Firehawk · 11-19-2012, 12:36 AM

So I didn't want to create a new thread on this, so I'm raising this one from the dead. I have a lot of new questions to ask...

After looking at Staples results on his Stage II on meth, it got me thinking. What is the weak link on the our stock bottom motor? I was thinking pistons. And what was the 550whp limiter that came up to this "max" number? I know torque was a big factor, but I saw that as more of an impact on drivetrain. I was looking around on here for a couple hours and couldn't find the concrete answer I was searching for.

Now here is the second part of the question. If high octane (E85) and meth injection prevent detonation, why do I only see meth injection as the defacto way of doing things? Why has there not been a FI'd E85 running stock guts or compression? Hell, is it possible to tune the motor to use both?

I'm still going back and forth on what I want to do, but it's coming down to BP's kit and the GTM twin SC kit. They are both very different from each other. I know that no matter which way I slice it, the turbo will make more hp and tq in the middle of the power band and at lower boost pressures. But this is what my concerns are and it's not the kit, but my environment. It routinely breaks 100 in Las Vegas, I would say for 1/4 the year is over 100 degrees. The turbo is going to put a higher heat load for the oil cooler and radiator to dissipate. I will be upgrading the stock radiator with what ever I choose to do, even stick to NA, it's just the smart thing to do. I don't know how much overhead is in my system and I don't want hot weather to impede on my fun button on the floor. My headers, intake and Y pipe all have to be removed and sold. Yes money back in my pocket, but it's a PITA to sell things, and even a bigger PITA to remove the headers. There are a lot of exhaust changes to make it happen. I think the whole system is top notch and a much larger value than any FI product available.

The twin supercharger packaging allows me to keep everything off my headers the same. And I still have the choice to run with or without a cat. The motor still keeps it's stock characteristics, but with a lot more go. I wouldn't have bought the car if I didn't like the motor and how it build power. The Rotrex SC's are pretty awesome. They basically have a mini CVT. They have their own oil cooler. There is no additional load from them on my existing oil cooler and it can just work on keeping motor oil cool. Again radiator will be upgraded and with the whole front end coming off for the install, that makes things super easy. The torque doesn't go anywhere but up, almost like the hp curve, and the motor doesn't stop making power until redline. No flat spots, no dips, just smooth power. With wanting to jump into some track events on occasion, I think the supercharger might be the better way to go.

Lastly, does it make sense for me to run E85 instead of meth or have ability to run both depending on fuel? I'm looking at this as a cooling and reliability standpoint. I don't know how meth/water is tuned or if it can be turned off with a map change. Can't help but think about the benefits these have with the hot weather and elevation.

I know I asked a bunch of questions and appreciate the help. My Wife is on board with everything. She is taking the car in December for an oil change, spark plug change, resonator install, a M370 reinstall, tune check and some dyno passes with the resonator and HFC. I'm hoping the cooler weather will give me a more accurate look at my baseline and untuned numbers from Feb and March earlier this year. These are the last round of mods before she goes dormant till I get home. Thanks all in advance for the help

theDreamer · 11-19-2012, 06:30 AM

To try to hit a few of your keys points.
-You can do meth & E85, just need a good tuner which there are plenty that can do it.
-E85 is not popular because 1) a lot of guys are getting the power they want on just 91/93 octane fuel 2) E85 is slowly going away in many cities. I have seen some stations stop offering it which limits the ability to run the fuel.

Now the plus side to Uprev is you can run multiple tunes so if you want E85 for a week then you have that map and then want 93 you can run on that with just a quick switch of a tune. I am honestly curious to see how the engine will run, without any engine work, on just E85 & meth and to see if there are any benefits.

You might send an email off to Sam at GTM and to BP about your ideas and see what they say. They both may jump at it or maybe caution that meth plus 93 oct is enough.

SS_Firehawk · 11-19-2012, 07:15 AM

Thanks for the suggestions and answers Dreamer. With me being away from my car for another 9 months, I emailed GTM over the weekend. Gave some options regarding my car, their twin SC kit, whether they want to do it, or have my local shop do it. Didn't discuss the fuel and meth questions I had as this was an epiphany last night while looking at Staples dyno sheet. And down the rabbit hole I went looking for answers. But haven't been successful.

I guess the big underlying question that I've failed to point out is will E85 or 91/93 (only one station in Vegas carries 93) + meth or e85+meth help stock motors hold up with forced induction. 12 PSI was kind of known as the glass ceiling before reliability is compromised. Would the aforementioned push those boundaries of reliability further? What physically breaks if detonation is not the culprit? I don't know all what the FI guys are modifying in their motors besides lowering compression or increasing displacement.

If the only purpose of reducing compression ratio is to have a larger safety net when running FI, why can't the E85+ meth do the same job with the benefits that comes with it. A cool running high compression FI motor sounds like a dream for performance and efficiency. Lean out the fuel and advance the timing, it could be a wrecking ball on or off boost.

Disclaimer: I am only theorizing and am no expert. I'm presenting questions because I'm ignorant and could not answer these myself. Please don't tell me to buy another vehicle or build my motor, I'm just throwing ideas out that could be useful in some capacity, and maybe not anything I'm doing, but for someone else.

MyKindaGuise · 11-19-2012, 07:53 AM

The part that holds us all back from passing 550whp 500tq is the connecting rods. They will break if put under anymore strain. Boost is not a limiting factor. I am working on a custom setup myself. E85 will be run full time in my car. We are using a turbo that hasnt been used before but we are aiming for 15-20lbs. E85 makes it almost impossible to predet.

E85 is not going away.lol The US is looking to roll out different grades of ethanol based fuels. Also Every Sheetz gas station in central PA has undergone the process to carry E85 so if anything its growing in popularity.

SS_Firehawk · 11-20-2012, 06:53 AM

Being in Las Vegas, I haven't seen a problem finding E85, but 93 is nearly nonexistent. There is seriously one gas station I found off of I15 and Charleston Blvd.

I mentioned the 550whp limitation in a previous post, I understand what your trying point out, I was just mentioning another limitation number being thrown around. The primary reason I'm looking at these options is the extreme heat. It will help maintain consistent power and prevent timing from being pulled because of heat.

I do have the NST pulley system on the car, but the belt size difference is so minor, I'm not sure if it will pose a problem with this kit, I believe the same serpentine belt is still running through the crank and alternator. Would it be recommended to upgrade the fuel pump and injectors on w/e I order? And if so, what size would be recommended?

Chuck33079 · 11-20-2012, 07:34 AM

FWIW, I was running 93+meth on my STI. I asked my tuner about E85+meth, and he talked me out of it. From what he said, the E85 is actually a higher octane than 93 with a 50/50 water/meth mix. In effect, I would be lowering the octane of the fuel by adding the meth in. If you're staying with bolt-ons, you would only need a fuel pump and injectors if you plan on running E85. 91 shouldn't need it.

Thanks for the clarification. Wasn't sure the octane value of meth. I would definitely prefer just E85, not necessarily for any power improvement, but as stated before, the cooling properties. It's just a bonus for me that it's more efficient. This would most likely be done for FI, not NA. I'm expecting a drop in over all psi with the headers, hoping to still make the advertised amount going to SC option.

Chuck33079 · 11-20-2012, 08:06 AM

If I had regular access to E85, the thought of meth never would have crossed my mind. The additional octane was nice, as it allowed me another 4 psi. The cooling effect dropped my EGTs about 150 degrees at WOT. Still, I never felt 100% comfortable with it since it introduced another point of failure to the system. Even with the failsafes, if the kit fails under boost it's likely you just bought yourself a new motor.

SS_Firehawk · 11-20-2012, 09:36 AM

How much psi are you pushing? Ever get it to the dyno yet? Weather is starting be friendlier in your area.

Chuck33079 · 11-20-2012, 09:40 AM

On the Z? Only 9psi. Haven't gotten it to a dyno yet, but that's on the to-do list for next month. I was referring to the STI I used to have. I was able to go from 20 psi to 24, with a drop in egts by running meth.

elperuano · 11-20-2012, 11:17 AM

E85 is a lot more complex to run.. You'll need fuel pump injectors and lines to make it work properly.. I've only seen then used on big builds with big numbers. For stock block e85 is not necessary as you'll be reaching the limits of what the stock block can handle on pump gas. You COULD run either e85 or meth for extra piece of mind I suppose.

Firehawk you got a lot of questions there but u need to decide which route YOU wanna go.
No FI is safer than the other, it's all in the tune. Superchargers r nice, turbos r even better IMO. The torque is a blast and to get kicked back in the seat is something only turbos can give you. If you're lookin to build the motor later down the road then I'd suggest turbos. If ur sticking to stock block I'd still suggest turbos. Judging by how you seem to be worried about keepin the motor safe then you're "safest" bet would be supercharger. You'll get hp but no real torque. That will help you stay somewhat on the "safer" side with a good tune. Just remember once you go FI it is hard to ever go backwards. You won't wanna ever turn down boost, you'll almost certainly want more. More boost, more mods to turn up boost "safely".
Best bet is to decide ur future goals and go with that plan in mind to grow later down the road. A nice turbo will keep u happy on stock and if u ever decide to build you can always turn up the boost and still be happy. Once u to supercharger that's about it, to get more gains will cost u more money on an upgrade when a turbo can do all that from he beginning to end.
I'd suggest either Gtm or Sasha's kit. Good luck.

SS_Firehawk · 11-20-2012, 01:30 PM

I'm not looking at E85 as a plateau buster of power. In terms of power output, both will reach my goals and have plenty of reserve to hit 650-700whp with a built motor, possibly more. It runs so much cooler than 91 or 93, and don't need to run meth. With E85, I can run at lower boost levels, lower temps, and it's readily available. I can switch the tune to 91/93 if needed.

Now, if someone offers to buy my long tube headers and Y pipe with a cat and optional resonators at a price that makes it worth it to take off, I'm all ears. It's $1800 brand new and would only be worth the trouble if I sell for 3/4 the price. Now if someone offered $1800 for my full exhaust setup, I'd get rid of it and go BP with the F.I. exhaust on it. But selling stuff is a different thread and haven't put much thought into it. My exhaust sounds like no other 370Z I've heard, much higher pitched, it's an anomaly. I now have sentimental feelings toward it :P It's a PITA to part stuff off, and a big reason I'm looking at the GTM TSC kit.

elperuano · 11-20-2012, 01:47 PM

It's always hard to part out.... But would definitely be worth it if ur goin FI.. You'll definitely be much happier with the end result.

DIGItonium · 11-20-2012, 01:47 PM

Cars are terrible investments, so it depends on how long you plan to keep the car and whether it is worthwhile. Honestly, forced fed is super fun and well worth it! It sounds so good.

Yet, I still lust for an NSX (let alone a twin turbocharged one). [shrugs]

It's $1800 brand new and would only be worth the trouble if I sell for 3/4 the price. Now if someone offered $1800 for my full exhaust setup, I'd get rid of it and go BP with the F.I. exhaust on it. But selling stuff is a different thread and haven't put much thought into it. My exhaust sounds like no other 370Z I've heard, much higher pitched, it's an anomaly. I now have sentimental feelings toward it :P It's a PITA to part stuff off, and a big reason I'm looking at the GTM TSC kit. elperuano likes this. __________________ Old Car:GTM TSC'd 550whp / 410lbft tq @ 11.88PSI New Car: Under Construction

Honestly, forced fed is super fun and well worth it! It sounds so good. Yet, I still lust for an NSX (let alone a twin turbocharged one). [shrugs] __________________
