GTM SC stage 1 vs GTM MHI TT vs FI TT
 

Hello,

Once again in other dilemma, so after deciding to keep my 370z I've decided to go Forced induction route however I'm unsure which to choose since they each got their pros and cons.


So far:

GTM SC

Pros:
-Available locally
-Very Good price(~3450$)
-Less headache, good for DD

Cons:
-used(not really a con)


GTM TT

Pros:
-Cheapest twin turbo
-Turbo over SC(since my dream is to have a turbo)
-price ~7000$

Cons:
-Terrible customer service
-delivery date not announced


FI TT

Pros:
-Super clean looks(need that for car passing here)
-Better customer service than GTM
-More power? maybe

Cons:
-Really expensive (~10,000$)


Now with all the above its seems the SC is the best route however I keep rethinking it and try to convince myself to save up and go turbo instead. I'm really baffled right now.

Any opinions/input appreciated.
Also this isn't "which is better" thread, simply seeking input from other people so it might influence my decision.


Thanks

I'm not sure where "Dubs" is located but if they have a Nissan community you should go to a meet and feel and hear the difference between a sc vs tt. They are two different animals. One is linear and loud when off throttle (bypass valve), and one is torquey and more upgradeable when you hit that point.

It also depends if your doing the build yourself and how knowledgeable you are in mechanics. Lots of variables here. But if your dream is to have a turbo why cut yourself short of that only to get something you didn't really want in the first place.

Take some advice...do it right the first time.

Let me be the first to say that there is a lot more that goes into a proper FI setup then just the purchase of the kit. As a rule of thumb I would add at least $5k for clutch, heat management (oil cooler, radiator upgrade, wrapping, etc.), gauges, etc. Not to mention that you will have probably $1,500-2,000 in labor for SC install and upwards of $3k for either turbo setup.

All that being said I vote for turbo!!! I went with the BP kit cause I can install it myself in the garage.

It's Dubai :p, I've already considered all the additions plus the SC kit includes oil cooler and tranny cooler. It's basically the price of the SC which is making me lean towards it. In terms of power and feels of both , doesn't really matter to me since I'm pretty sure they're both fun to drive.

Well if it doesnt really matter to you then this thread is pointless. Carry on with the cheapest route.

Hard to beat the price of the SC kit. If you aren't power hungry, I would pick that up and get the supporting mods you need. Throw on a custom tune and call it a day

I'm definitely not power hungry yet, my goal is about 400+ whp.
I think thats what I'm gonna do, after watching your twin SC videos it really made want to stick to the supercharger.

What supporting mods do you recommend besides a clutch and flywheel.


Thanks for the advice

I meant more of the max power, both will make approximately the same for my target. Of course the turbo is much more fun to drive when it gets into boost and sounds much better :P, but the supercharger is good too just not as good as the turbo IMO.

Anyway I think i've made up my mind.
Thanks for the input

That's easy. Just look at his sig. But a csc and monitor gauges are your musts.

No for SC. These engines are so small and SCing it wont help.. Look at the torque of the SC.. almost same as stock AMG and M power.

Turbo is the game changer!!

I vote for Boost performance turbo kit if you drive M.T

Doesn't seem like the boosted performance kit is stealthy enough to pass inspection here. I don't know how the other guys here are doing it, they got full twin turbo super clear under the hood or engine swaps and their cars pass. They don't wanna share the secret :P. I'm still thinking about it, sparada on gtz has his kit for 13,500 dhs whereas a turbo kit would cost me about 26,000 with shipping. Touch decision !

And yes I drive a M/T

Well. Im telling you, SC will not satisfy you (it wont satisfy me atleast)

The statement of SC being DD while turbo cant is totally wrong, SC is always on Boost while Turbo only goes on boost after you put some more throttle, So whos the DD now?

As i said Turbo is the game changer.

Go for Boosted performance . Ask Sasha to powder coat your pipes and intercooler if you're looking for stealth.

One other thing. Who the hell quoted you 26k dollars for your turbo kit shipped? wtf?

I meant 26k dhs lol I cant find any details about the boosted performance one. From the pictures it looks like the turbo is mounted in the exhaust piping which definitely wont pass inspection.

Only reason I decided going Forced induction is because of stock look the GTM and Fast Intentions ones give. There's a high chance the inspectors might miss it.

I also agree with you about the turbo being a gamechanger but I guess i was trying to convince myself the SC is better.

Thanks,

Lol okay, thought youre talking about $. Well you can always PM/call me if you need any help in decisions.

I have said it before and will say it again but VSR out of tampa has a single turbo turn key kit for $8500 tune included, done.. Great customer service and lots of z' and g' with that kit with No issues...
I would have went that route instead of gtm if only I knew. That FI kit looks sweet but after a new clutch, tune, etc, etc, your going to be right at around 15k before its all said and done.

Just FYI if your going with any tt kit in dubai, the turbos are easy to spot and you will fail inspection irrespective of fast intentions or gtm.
Also when buying a used SC, do note that kit has had 2 other owners atleast (maybe more) and it maybe missing many parts. Price looks cheap but you may end up spending quite a bit especially if parts are missing you need to contact gtm and get it which could take a couple of years at this rate.

Look at an exhaust & oil cooler, at least a 34 row for Dubai.

Stock clutch will be okay for a stage one SC. If you do buy a new one, getting a flywheel will make the supercharger more efficient. And replace the CSC with a Zspeed CSC while you're down there.

You could also order a light weight stock size crank pulley from NST to increase efficiency and response.

No need to remove stock catalytic converters, the kit prefers some backpressure. You should have a healthy 430ish whp with these mods and a custom tune. And it will not cost an arm and a leg.

G37, to correct you on the SC, the rotrex unit by GTM is not always in boost because it is a centrifugal unit. Roots style is the system that is instantly in boost and building pressure, where the rotrex is more 'turbo' in building pressure at around 2500-3000.

On the topic of what the OP should do, is he needs to really uncover more details on this used SC kit and what is missing and what other cost will need to be done. I have seen a few guys pick up used kits (TT or SC) and they are missing parts or damaged parts and it is more costly to get the parts replaced in the end because of the individual price purchase. Where a new product gets a little discount because you are buying it all together.

On your notion of wanting a turbo, I would suggest go that route, if you really want that turbo feel & power then I would go that route.

To add to the debate, this is the BP Performance kit, no turbo showing.

You've left off the GTM Garrett kit, which is more of a competitor to the FI kit. It should be available immediate/y (as close to immediately as GTM gets).

Theres only 3 real FI solutions for this platform, they are;

Greddy TT Kit

GTM TT kit

FI TT kit

the rest of them are just noise.

I beg to differ. Boosted Performance makes a nice product.

boost performance should be on top

I agree, my car makes so much more noise SC'd.

oh yeah the BP kit is stealthy until the inspector bends over and looks under the car and wants to know why there is 30ft of tubing and a turbo hanging down

Limited Edition :tup:

No kit will ever sneak past inspection. If u think it will u are a fool the only way is to find the right inspector and lubricate his pockets a little

Trust me it can pass because I've seen many. There's cameras all over the place and you're not allowed to enter the test bay. "Lubrication" is not possible :p

usually the "lubrication" happens off site at another time. you find a guy who knows a guy who hooks up with a number you call to meet a guy you pay him and then he tells you when to bring your car in, and then the turbos magically aren't found. Here you get a recomendation, that person calls the guy to tell him your legit, then you go meet him hand him your paperwork and pay and it just happens magically and you get your new papers in the mail. talk to some of the guys in a local car club that have done it, make friends with them and they will hook you up the penalties are so big that a lot of times it takes a while to actually get them to tell you. also sometimes it helps to go to a small town place that dealers with people who can't afford to bring their cars up to spec also.

"I keep my car stock personally so i don't have to worry when it comes time for smogging";)

if your confident go right ahead. good luck with the build.
hope you have found an uprev tuner in dubai?

That's the only problem, I'm not very confident it will pass but what I meant is there's a chance with the gtm kit since the inspectors aren't gonna dig deep if it looks stock. I don't wanna drop 8-10k usd then it fails.

there has to be a back door guy in dubai because either the inspectors are morons or blind if they miss things like i dunno the lack of airboxes, the inter-cooler up front, the blow off valves opening (guess they are deaf too huh?), that all kits have.

I'd worry about the install and more importantly UpRev tuning at the time being rather than passing inspection.

There is no way on earth you're hiding a turbo'd car from inspectors, end of story. Some tend to overlook it, but doesn't mean they missed it.

There's still a chance they'll miss it :p , let's say I got it installed an tuned properly, if I can't get it passed all of it would go to waste.

God I love living in Texas. You throwing any codes, nope. Ok, you're good to go.

learn how to install the kit (or keep aside labour charges each year for removal and reinstallation of kit), that way IF it does not pass you can remove it for testing and install again.

Maybe you missed it but finding an uprev tuner will be more difficult than the annual inspection.

I'm just going to say that I have seen both the FI and BP kits installed and both are clean as they come. If you are looking for a nonintrusive oem look these kits will do the job, but you got to be pretty damn naïve or just don't care to miss a boosted Z!
