VTEC is no joke.
i have decided i am going to do a mod motor. You can get so much more out of those than a pushrod without doing as much...
somethingclever i am still confused about what you are saying. Is there some place that i can read and go more in depth about it? I am on turbostangs.com right now reading up as much as possible before i buy this stuff in the middle of novemeber
Keep in mind that the parts cost more and you are going to need an engine management system to control everything cause your current computer will not work with all the additional sensors on the mod motor. Also, every turbo application I have seen with a mod motor also requires changing the k-member out for a tubular one (Of course you'll need this anyways to set the mod motor between the frame rails) as well as all the other things you will need to make the mod motor work in your car. I would say you're looking at $10k - $12k minimum to convert your car over to a mod motor plus do a turbo kit on it. Research carefully and buy smart!

Scott, before this question can be answered, I need to know what kind of power do you want to make, is there a certain 1/4 mile time/mph that you want, will the car be a DD or a a street/strip only car? Will you buying a new car or trying to do this with the car you have?
I've been through this myself recently so I should be able to give you some insite once I know what you want.

kicker!!!!
stick with the winsor based motor, what your wanting to do been done over and over again. dont try and invent the wheel, do what has been proven. 500rwhp in a fox or sn95 isplenty. its about 300 more then you could probably handle without killing yoruself
If you do a mod motor do a 4valve, very easy to make power with minimal engine mods, if you want to stay under 500rwhp you will be able to do it on a stock 99-01 cobra without getting a forged bottom end, with a good safe tune it will last for a while. When you want to make big power have the bottom end done and the neccessary supporting mods and you can make over 700rwhp with no problem. When you decide what turbos to get give Terry a call at Streetlethal Performance as he will be making the same kit that's on my old Cobra and it should support over 1000rwhp, that's if you buy a 99-01 Cobra, if you plan on doing this to your car then it will probably cost you alot to convert over, probably better off just getting a 99-01 cobra and starting there.

i am going to be doing this with a 96-01 cobra. I know it would cost way to much to put my car over to a mod motor and put the turbos on then. Right now i want to hit 500rwhp but with a windsor block iw ould be close to more than the block can handle and once i get to the 500rwhp mark i want to be able to go higher if i wish which i can not do with a windsor unlike the mod motor where i will have so room to improve on.
For only that much hp i personally wouldnt go to the cost/hastle of a turbo setup... Or if i was hell-bent on going that way, look into a STS kit... from what i hear, the turbo lag is very minimal in comparison to a reg. turbo setup, and you can do a twin setup if you like...
But for 500whp, twin-screw all the way.... but that's just my opinion... Good luck ... !!!

and we can all thank ed for putting this thought in my head when he brought out his new car. lol hahaha
well a twin-screw would obviously make power immediately, and theres no reason it wouldnt work on something else.... you'd just be looking at a lot of work... everyone uses centrifuagal b/c they're an easy install that just about anyone can do in their garage at home...
Twins will spool up quicker in most situations, but you will definitely be able to make a single turbo PT76 or something similar spool by 3000-3500 (especially if it were a BB turbo) and you'd be looking at a lot cheaper kit...
and similar turbo to that above iwll make well more than 500whp...

they do make twin screws for my car and the most hp i have see was like low 400s
