But anyway. Even a stone stocker should be getting at least 20-22mpg.

now, i don't want you to take offense to this because i'm honestly not trying to be a tool either, but i'm going to challenge you.

option A: tell me everything that is wrong with this post in your next post

option B: go read up on these cars before you try any engine swaps or turbocharging or anything.

bro to make 200 horses you dont need all this crap=upgrade the suspension, brakes flywheel( not every one is as rich as u) stock brakes work fine. they lock up anyways. what good is a brake upgrade when the car is going to skid anyways. unless your driving on elmer street. come on

I hope you realize that this thread is over 2 years old.

Yes, there are alot of quick cars out there now. However this section of the forum is not really about drag racing or such. It's about the basic mods and streetable HP vehicles. :-)

What you are missing here is that we are about safety and the capabilities of the vehicle.

When you Double the hp of a vehicle all factors change. In order to make the vehicle safe you have to now determine other factors.

Such as the vehicles top speed. It's ability to accelerate quicker thru corners, etc...
You are correct on braking if normal speeds are being used as a base.
With more HP you need to have the vehicle stay planted on the pavement when accelerating.
Better springs.sway bars, etc will help ensure that the vehicle is more stable with that type of added HP when cornering.

It is all a matter of how the car is going to be driven.

Whatever happened to FBII's car anyway? I know he sold his turbo setup a long time ago, but I've not seen him on here in forever.

And I'm a firm believer that suspension is far more important than the power any day of the week. Sure its nice to go faster, but its a lot more fun to go around corners faster. With stock suspension, you're not going to take corners faster than you could stock. And its definitely going to add a lot more danger (and taking corners in an FB are far from the safest feeling thing in the world to begin with, which is why its so fun).

And the grave digger obviously had to search something on this thread, which leads me to believe that he read a lot more before this thread as well.

I'm just curious. Is it possible to use a K-03 turbo off a volkswagen on a 12A? Or will I have to spend craploads of time and money to get my hands on the stuff for a TII swap?

possible? yes ... but probably ill-advised. just get the stock Hitachi used on the Gen II cars and build your 12A setup around it.

Man, that's gonna be near impossible, since I'm unable to get stuff online. Plus, my local salvage yard has never seen a TII, and the specailty shop probably has one, but will charge an arm and a leg. Anybody in Calgary have a spare turbo kickin' around? Otherwise the K-03's goin' in.
