The FD wheel offset is 50 which equates to a little less than 6" BS. I use a pair of the early editions on the FC for my race tires and they weigh 13# each. Would need one hell of an spacer to fit them.

Someone put a post on zcar.com wondering why we did not see Zs on Barrett-Jackson. Hmmmmmm.

Yes, that is the small NPR. I am a big advocate of the NPR but given what is abailable today on eBay, I would say that might be a better way to go. Find out who here has bought one and how it is working for them.

Good comments but sorry, I have to disagree on the recommendation for forged pistons. His HP goal is 275-300hp (yea, right!) and even another 30-40hp beyond that, there is no need to even open the engine or put in a cam if the focus is on limiting detonation. I think too many folks underestimate the strength of stock turbo engines when tuned right. I say for up to 350hp, focus on quality bolt-ons and tuning. When you decide to get serious about power (300hp is not serious) then you start working on increasing the flow with headwork, cam, full T04 and forged pistons for extra insurance.

Boy, you have gotten a LOT of great advice in this post, maybe even too much In summary, 9.2:1 cr/cam (higher RPMs)/91-octane/stock turbo/2.5" exhaust is not a good combo. Instead of spending money on a rebuilt T3, get an upgraded hybrid for probably not much more. Instead of 2.5" exhaust, spend a little more for 3". Skip the cam and spend the money on an alky-injection system. Read, read, read and understand the basic principles of turbocharging so you can properly tune, tune, tune the engine management system. That one is free. I know a lot of folks think it is OK to push the stock T3 to 17-18psi because they can and it saves money but they would be surprised at how much heat that generates. In your case if you are going to spend money for a turbo, do not get a T3. With an upgraded turbo you make the same power from a lot less boost and a lot less heat. Do not focus on HP. Focus your combo and tuning to reduce heat and detonation and the HP will be there because you will be able to run more boost safely.

Agree with this statement and while I am not singing the praises of hypers, hypers have come a long way in their development. I use SpeedPros with coated skirts and running 25psi boost with pump gas/alky inj. Well over 520rwhp with more to come. Ironically, some of the stigma on hypers and forced induction have come from KBs but mostly from owners who do not take the care or have the skill/knowledge to avoid detonation. I do not know enough about KBs development of hypers over the years but I would not put a specific piston in a forced induction engine just because I can get them "cheap". Be honest with yourself in answering the question about how diligent (anal actually) and good you are at tuning a supercharged engine and how good your engine management and tuning equipment are. If the answer is so-so, then do not use the KBs and you are still in danger with forged as Grumpy said.

Personally I do not think an Alpine is good car to do any kind of swap but the SR20 would probably be a nice choice. BTW, wanna know just how tight the engine compartment was? The tranny tunnel had a hole on each side with a rubber plug. Those were there so you could get the rear spark plugs out.

Congrats John! Have you calculated the converter slip yet? Anxious to see how it does on the track.

A Tiger is more than just an Alpine with a modified firewall. I owned 3 of them and while a classic and a car with performance potential when the right mods are done, in stock form they were not a very good or fast car. Having owned and worked on them, my advice would be to not attempt this swap. Not only will it be a major PITA, but if it ends up as good as a stock Tiger, you do not have a Tiger but you have all the flaws of the stock Tiger. Just my $.02.

...and with an L28ET, why would you want to? The issue is not boost but detonation. You have a good turbo, injs and I/C, so carefully tune the SDS to avoid detonation and you have nothing to worry about, certainly not with a t3/t04. The more you tune to avoid detonation, the more boost you can run, the more power you can make...safely.

How about the rest of us that want to get in on some of that action? Not working for me and I have IE. OTOH, if it is another 4000+lb behemoth "supercar", I will save my squirts.

You make good points particularly in the fact that most of the cooling is done within the 1st 6" or the tubes. I experienced some serious pressure drop when I hit about 400rwhp and that was with the BIG NPR so the medium is just fine for what you have.

Jeremy, not sure exactly what point you are trying to make. A medium NPR is not too big for your turbo/boost level. What you describe is exactly what an I/C should be doing.

"oxcart"

5.68 is 8.90s. DAYUMM! I cannot wait to see this car roll at the SEZ. Anyone in the area that does not come out to see, support and cheer this car needs to have their head examined. BTW, the car went quicker with taller gears! What a shock

:cheers: :cheers:

AWESOME!

The side wings are so passengers can step on it as they enter/exit the vehicle. After all, it is a taxi, isnt it?

Very Nice! Whats the 60' times? Caught that bike napping and sure he was surprised.

AWESOME! Anyone planning to come over and need directions, please drop me an email or PM. I will not post directions to my home or my tel # on the Internet. Let me know where you are coming from.

Get thing tuned and you might finally start pulling some decent HP out of that sled :D
