actually no. The original post quote was 20-25k. Seeing how I just purchased soho’s (stage 2.5) kit.. upgraded to 1300cc injectors and upgraded the Ecuadorian and it was 11k I still call 20k price tag bull****.


The kit has 2 stars in difficulty ... (I’ve swapped out multiple engines into my g37s) 2 stars isn’t ****. Works with my existing headers etc. so with getting their most expensive kit... with extras that I’m going to put in myself I’m around 11k. I plan on buying the fuel return kit which is around 700 dollars. Already have my clutch installed. So at this point after I put the kit on I’m just looking at tuning.

tuning doesn’t cost 10-15k. Now if we’re talking about “building the engine” (which I don’t think the op should do since it’s just a daily driver) yes.. the costs can rise.

now to the OP.

I think you should stick with a supercharger. They’re pretty reliable. I would go forward the stillin kit because it’s 50 state legal. If you want more power call up soho Motorsports and get their Air to air fmic... then get it tuned and have fun.

ps: I talked to seb at specialty z and he quoted me 20k with building the engine and them doing all of the instillation. That’s still 5k less than the 25 at the high end.

FI wouldn’t even sell me a kit.

but clicking things in a webpage without context is cool too

i think the single stage one turbo kit could be done well under 15k. "doing it right" is subjective. doing it right for street? doing it right for drag? doing it right for track.. all different answers.

What are you talking about? The first list is literally the itemized list you requested and it's even for a SOHO unit. The list was comprised of a ground up build and included shop labor in the event someone doesn't have the mechanical know how to do it themselves. @jpowersjr2 list also included a clutch and flywheel upgrade which you're excluding because it's 'already done' but it's still part of your build is it not? Include that cost into your build; as well as the tune and you're pretty damn close to what he estimated...You're moving the goal posts by referencing a spec'd build with Fast Intentions which is where his 20-25k figure came from. Even then, he gave you exactly what you asked for.

You called him out and he responded with everything and then some. Happens man

Its just context which im speaking. Can I build a 50k turbo system? Yes? Do I have to for daily use? No. When people see the 20-25k pricetag it usually turns them off of the idea. (i know... context.. that was for the twin turbo kit)... if you cant wrench on your own vehicle then you shouldnt be buying a turbo kit. Things are going to break... if you dont mind paying for things when they break then the price really doesnt matter cuz you're a baller. Its all good bro. I dont post here much so i would predict there would be some bias. With said stillen kit that I was speaking of he would be able to run stock clutch with it. again.. its context.. Just because you can click every box in the invoice doesnt mean you have to. Most people already have alot of modifications to their vehicle where they wouldnt have to purchase extra stuff they dont need. Scaring people off with 15k price tags... or even worse 20-25k is just not a nice thing to do. Stillen kit he could get near 400hp and be happy.

11k and 15k seem equally scary for someone who agonizes over which valve stem caps to buy... which probably describes most people here.

With regard to kindness and humility, your response wasn't unkind, so there's that.

His list was a ground up build. Going from stock to a solid FI set-up. Not a 5 year build where you already did clutch, suspension, brake, wheel upgrades then said "ya know, I'm boosting the ol' girl". Even though it wasn't part of the kit doesn't mean it isn't part of the build.

Can it be done cheaper? Sure, but a Fast Intentions twin kit is an option many were going with before the single set-ups started popping up the last year or so. Even going with a SOHO or topgunz kit could potentially land you close to the 20k mark if you're running a 7AT. When the stock unit lets go, you're options are Level 10 or sourcing a 3.0t Q50 7AT and installing yourself or by shop. Figure another 5k for Level 10 or 2.5k - 3k for a Q50 3.0 transmission and the overall build is pretty close. Yea, it's a lot but it's a realistic figure of what it takes to go from stock to a solid TT FI set-up. Share the itemized list of how much you've spent on your G since you became the owner. I'd be curious to see what your overall build is once we add everything up.

No bias at all man! Love seeing new members come in with new builds. Makes me want to get another G lol. That said, you asked, @jpowersjr2 delivered. Time to move on. Really look forward to your build though. Is there a reason you went with the SOHO over something like the TopGunz set-up (what I would personally do)? SOHO makes a great little kit but seeing the results of the TopGunz kit makes me wonder why even go through the hassle of a single set-up.

for sure brother no hard feelings. To be honest I didnt know that TopGunz sold a turbo kit... I thought they made a supercharger kit. I wanted turbo. I've owend an Evo 8, srt-4 and also a cts-v. CTS-V was amazing (but) i wasnt much of a fan of the supercharger but i absolutely loved the turbo's with the srt-4 and especially my Evo 8. I like the way the power is delivered.. i love the way the turbo spools and splashes all over the place. I actually enjoyed the turbo lag from my 35r in my evo.. nothing a quick downshift couldnt fix lol. I've owned both turbo and supercharger (be it a different type of supercharger) i just like the way turbo's work. I'm more familiar with the way turbos operate as well.. I cant say i know very much about superchargers and their functionality. I researched the pro's and cons of twin vs single and i decided to go with single. The use for my build would be high speed pulls and 1/2 mile when i want to. I'm not going to be tracking it or 1/4 mile. I chose single larger turbo for the higher end which most freeway pulls are. It was buy this kit (which i think is the best single turbo kit on the market.. but i am bias) or sell it and get a 2017 zl1. 650hp 650tq.. but then i would have a pretty significant payment and still have to put money into it to be fast. With my setup i am planning on being able to make FBO hellcats struggle to keep up with me. I also wanted to be different... there are like 5 total soho motorsports single turbo kits on youtube and there isnt much context on it.. thinking about starting a little channel myself and seeing where that takes me.

@Broken_2008_G37 the topgunz kit is still a posi set-up (I believe a Vortech 3i unit or something) but it's far superior to the stock Stillen kit and there's growth there. Can't really go wrong with either FI set-up. Like you said, really depends on the power delivery you prefer. Even different superchargers have different deliveries and impacts on the power band. The roots or TVS set-up will have that down low - mid range push where the posi have more top end impact; similar to a turbo. After 600 whp, you almost need a drag radial to put any power down; and at $2k/tire it's something that's tempered my aspirations for the Mustang build.

Yeah I'm thinking about picking up some 15's and throwing some mickey thompsons on there. strickly for when im going out hunting.. otherwise i'll be putting the fattest stickyest tires on my stock ones for that "sleeper" look. I would still consider a turbo g37s as a sleeper. especially since you cant really see the fmic from the front. i'd go as far as to getting a black one so it couldnt be seen. Im interested to see what the op went with. I'm still looking for an engine builder.. i have a 2nd vq37r that i already did the gallery gaskets on and went through it... if i dont find someone i'll just have to build the engine myself.

Might be worth asking in the regional forums. Can't imagine there isn't a few builders out there on the west coast who can put something together for you.
