Turbo kit.

 

As stated before, do you want easy bolt in or do you wanna do extra work? If you have plans in the future to push over 400whp, TVS isn't the way to go. If you wanna just get to 350 and hang out there forever, then the TVS is your solution. I would go turbo, which I am lol because later down the road I wanna go for 450+. I would think that in your case going TVS would be your best bet tho.

OTT Stage 3 kit- $2400ish, meth kit- $195(base kit) total ur still way under 3K

HAHN Lvl 5- $4400ish.

 

i picked the TVS for two reasons. one i already had the cooling mods and two its pretty simple to do. you just need to angle one sensor off to the side and swap over some sensors from the m62. hole job might take you one-two hours. there is always someone with more money and more power. what are you going to do with more then 350 in a FWD car anyway?if my m62 didnt fail, i would still be on it because i thought that a 2.6 and all the cooling mods was pretty stout. josh from ottp is my tuner and the customer service is top notch. you should just drive up to MI and have him tune you.

 

Well he did mine

And another s/c, and another stage 2 s/c this weekend. Just sayin

Yea our tune was pretty quick all things considered. Without adding anything or changing anything other than the tune, we could probably eek out a little bit more power, but nothing crazy though. I'm only running 16.5* of timing and timing is everything with the TVS. I'm not on meth (yet) and there's no E85 anywhere around here so if I had one or both of those, I could advance the timing a lot more and you'd see the numbers shoot up pretty quick.

 

i think I may do the TVS because this is a FWD car and i don't plan on having a drag racing monster, plus the TVS is cheaper.

My goal = 350hp. Do you guys think I can hit this without meth? Or would I need the meth kit, I'll prolly do the meth anyway, just don't understand it.

Can someone also explain the meth kits?

 

You will need to be running e85 or 110 octane if you want to get close to 350whp with a tvs .

 

Meth kits are what basically keep you supercharger and engine cooler and develop more power, but personally im in the same situation and im going turbo, sounds nicer to me and theres always a chance to advance even though you dont think you will. You never know. Plus do you wanna just do the simple bolt on cause your too lazy to do the work to say you did it and can be more proud of it? the more work you put into your car the more you can enjoy it!

 

Without meth (or E85) and on a stock head, I think 350whp would be a bit of a stretch.

If you're really thinking about going with the TVS check out these threads and read through them. Especially the FAQ, if you have a question about the TVS it's probably been answered somewhere in there. And my TVS dyno thread is cool just for seeing in one spot, all together what the TVS guys are putting down and with what mods.

Plus TVS = hotter engine thats why you need so many cooling mods. Its hard on the engine to have a hotter avg. engine temp, turbos you can keep the engine much cooler and develop more power.

 

Yes sir

 

Well i guess im gonna go with the turbo kit, thats the only practical way that I can see to hit at least 350.

It sucks because I want to do **** to my car because i got the itch, but I don;t have enough for the turbo kit yet, and it comes with the intercooler, so by buying an Heat Exchanger and OTTP long tube header I'd be wasting money if I go turbo eventually.

 

350 is very doable on the Stage 3 kit w/ meth. It all depends on what pulley you throw on the TVS. My previous build plans were as follows:

TVS w/ 2.8
Meth
Full 3" and header
80lb injectors
OTT Heat echanger

That's just the power mods and most were suspecting my setup to go over 340. I think 350 is easily doable on stock head and internals. You just need to have the right supporting mods to keep ur IAT2's in line.

 

yea, maybe i'm shooting too high with my goal. Maybe i should do the tvs and hit like 315 and call it a day.

I mean this is my daily driver.

 

Yea I think my 303whp isn't "a lot" but honestly, when I drive it sometimes I still think to myself about how unnecessarily fast it is.


...but it's just so much damn fun

 

You'd only be wasting money if you bought all that stuff and changed ur mind and decided to go turbo. Get this setup and I'll bet you hit 350+

Stage 3 kit w/ a 2.8 pulley
Longtubes
Full 3" exhaust
Progressive meth kit
Tune

IF you have it nearby and it's not a hassle, I suggest E85 as well.

 

Coming from someone who has ran the tvs pretty hard and has tested it on both 91/93 and e85 I think the TVS is a great choice. Not only for the money, but the ease of install and the overall powerband. I would rather have a lower overall hp but a better powerband then a higher hp and sloppy powerband. I dislike how turbo's don't have a lot of power until very very high rpms. My tvs setup had a great equal power band all throughout the rpm and I absolutely loved it.

 

my buddy has an evo and just recently bought some e85 around here somewhere so its availiable.

But I raise the question...is this practical, having to run e85 all the time when its my daily driver.

I think i'd rather just do what I can on 93 pump gas and call it a day...

 

Practicality could go either way. On 85 you could lose some MPG's, but its also around 40 cents cheaper per gallon than 93...at least where I live. So its a trade off, save 4 bucks on a 10 gallon fill up and lose maybe 40 or so miles outta the tank or stay 93 and keep relatively the same mileage, but pay a higher price at the pump

 

yea... i have to think about this.

 

Just from readin ur post, I'm gettin the feeling ur after numbers more than power. A 350whp turbo car is totally different than a 350whp blower car. If I were you, i'd go TVS and start small with the stock pulley, meth, and an aggressive tune. You might find it only nets you 300whp give or take, but once you feel that kind of power, you might call it quits. Then, if you decide you want more down the road its as simple as buying a different pulley and a retune.

 

true, i am still running a stock pulley and tune and everything, so a tvs will def feel alot different

 

Up to you man, and you wont have to spend to much more money with the turbo after all the mods you do with the tvs, because its worth it in the end to be patient if you do the thing you want more. That being the tvs now or waiting a bit longer for the turbo kit, looks pretty under the hood, sounds pretty, feels good.

 

youre not going to hit 350whp on pump with tvs

you need octane

 

There's no reason you should assume you're gunna have to spend 4 grand on a turbo kit. Patience and careful planning can net you a turbo kit for less. They are both great choices. I did all the cooling mods and everything else then decided to go turbo...you can always sell stuff and get some money back and it allows you to have some fun while you save up. I'm pushin at least 300whp on a craps magee tune and still got some bugs to work out with my kit so the hp deff comes easier with a turbo set up, but agreed it is a much more involved install.

 

Well my car is almost paid off so I may just play it safe this summer...ottp long tube header, their stage 2 kit and cooling mods. Then once my car is paid off do a tvs or turbo kit
