Personally if i owned an NA car (i do) i would choose to swap a L67 (i plan to) in to my car....i just cant see selling the car that i have put all the work in to

There are a lot of w-body L36'* around running turbos. I don't know what exactly is involved but they are crazy fast. Turbos are better than */C'* anyways. Much better topend and are more efficient. You say you are willing to pay up to $5K. I think that would be enough to turbo you're L36 and properly prep it if you do the work yourself.

I disagree. What do you use more often? Top end or bottom end? Personally, I use bottom end 95% of the time.

And a SC car is more efficient than a turbo. The boost is managed very efficiently. This isn't going to be a 'what is better' argument. Just pointing out the other half of the equation.

Glad i brought this topic up seems to got alot of people fired up about slapping on turbos and superchargers lol. I imagine it can get costly because you run into different problems here and there. But like someone said on this thread "to each his own" and i totaly agree with that. I plan on either hooking mine up with a turbo kit or super charger. But there are plenty of mods that im going to have to add before i get that far. I guess you go with whatever budget you can handle. I don't know about most people but i imagine 5K would be one hell of an expense. I live at home so that would take me about 4-5 months before i could seriously think about spending that sort of money. But another question i would like to ask is how much would a ZZ performance kit cost? There was several different things on there website that they recommend you get switched i figured it would run about 2K.... correct me if im wrong.

I'd say 2k would be the low end. You have alot of parts to collect first.

My cart total came to $1609.98 for everything (down to plugs and belts) to run L36 SS M90. That is with paying $400 for a used M90. You should be able to find a used M90 for around $100 which would put the grand total around $1300 - far from $2000!
Some may say that $1300 is still alot of money but you factor in that you are getting a ported M90, ported LIM, and fuel logs it doesn't seem bad at all!

FYI a Grand Prix at MIGPC dyno day got 253 WHP and over 300 ft/lbs.
His mods were cat/Ubend/res delete, open cone, and ZZP L36 SS Kit with GTP injectors and 4.0" SS pulley. Thats a gain close to 100 WHP and 100 ft/lbs.Try to get that power out of an N/A for $1300?

I would vote for either an L67 swap or adding a turbo. I wouldn't touch the SS M90 kit. It'* not worth it, IMHO. It turns your L36 into a freak with a supercharger, that falls somewhere between an L67 and an L36. It doesn't have a true identity. The L67 in my Park Avenue just turned my car into a Park Avenue Ultra. When I need parts, I just order up things for an Ultra. I've got L67 heads, L67 LIM, L67 TB, etc. The SS M90 kit puts the injectors in the LIM, yet there'* a blower strapped on top? What the hell? You've got a strange belt size to deal with (I just order a supercharger belt for a Park Avenue Ultra or a shorter belt of commonly know size for smaller pulleys). Granted, It'* all easy for you, as the owner, to deal with, but what happens when your try to sell your car? Who wants to own such an experiment?

You can get a good used L67 from a salvage year for cheep, and have a nice, normal car. I got my HD trans and L67 for $1400, motor had 72K and trans 62K.

But, if you don't want to do an L67 swap, I would say do a turbo. If your going to turn your car into a freak, you might as well do it right.

Your choice in this matter also depends on how unique you want your car to be. An L67 swap will give you plenty of performance options, and it has been done before. It'* a comparatively easy, reliable way to get power. However, if you want to be more on the fringe of 3800 performance, look into a custom forced induction setup (meaning an adapted supercharger or turbo). Or, if you want to play the hard way, try to make more power while remaining naturally aspirated.

Ultimately, you're going to spend a couple thousand dollars to get any kind of uncommon performance out of your car. It all depends on how much money you want to spend, and how much innovation you want to do. If you follow those who have gone before you, you're guaranteed solid power and reasonable cost. If you try to blaze a new trail your results aren't certain, but you'll have more of a unique ride.

As I see it, your options are as follows (in order of ease/reliability):

1. Buy a car with an L67
2. Install proven N/A L36 parts
3. Do an L67 swap
4. Install an SS M90 kit
5. Install a turbo kit
6. Try your own crazy setup

Well said.

For me, 1 and 2 weren't options. I needed boost and my car had a blown motor.

Seriously, just buy an L67 car. It'* much easier that way. Are you that attached to your car? The only thing that I regret about my car is that it is still a freak, an L67 in a non-Ultra Park Avenue. Oh well, I'll manage. But it'* your car, so you can do whatever you want. This is just my humble opinion.

That is what i was thinking about but adding a turbo would be so much more of an awe factor.

And also llBlazin_llLo, i'm not a master mechanic or anything but did your total of $1300 include new tranny parts? Cuz i know That putting a SS M90 kit on a GP GT and not having tranny problems might sound good, but the way i see it...that car is lighter..not sure how much but it seems to me that putting a m90 on a L36 without upgrading the strength in the non-hd tranny would be a really bad idea. Like Bill said. You probably spend 95% of the time in the bottom end. And having a tranny behind that L36 Happy Box boosted beast, that isn't up to par could be asking for trouble. Just my 2 cents.

Personally i want a Trubo..lol.
