how big is too big? when you can't make it fit. even though there are good deals to be had out there for 150 or so sometimes cheaper isn't always better. an intercooler is the second most important part in a turbo system next to the turbo or turbos. Dual density cores still offer better cooling yet. Not saying you should go that way but it is better to go overkill once rather than doing just enough and then paying a 150 more than you should have once you buy the dual density intercooler

The only downside to making it larger is increased boost response time... but in a drag racing application, that would be minor compared to the benefits of properly cooling the air.
Have you considered both air to air and air to water designs?

A cheap $150 ebay air-air IC can do wonders! Its waaaayyyyy better than none at all, and if you start talking money per efficiency, an ebay a2a is still at the top of the list too. Yes, you can spend $900 or more on an intercooler with better efficiency, but is the extra 10% of efficiency really worth a 500% price increase? To some hardcore racers, yes, maybe. But for the every day street guy, probably not.
As far as fabrication goes, if you have a welder and a way to cut pipe, its super easy to build your own setup. I wouldnt run an FI car without an intercooler at all.
Oh, and get the biggest one you can fit. There isn't such thing as too big..

i think he means how big can he go before it doesnt fit anymore. i saw some bar/plate coolers for couple hundred on ebay. looked reliable, prolly what im gonna do when i get to it. just search 26x12x4 i think. might be able to go bigger, but im not too sure on it... i think that is core size too...

car is a air to air setup. i cant afford to do a air to water right now.... maybe in a year or to...
as far as the ebay IC... id do that but i already have the material and all the equipment to build my own.. im not going against anything u guys are saying cuz u are saving me money but i just like to build my own stuff...
thanks for all the info... i really appreciate it

Match the intercooler core with the power/flow you plan on producing. If you use a larger than necessary core, you could limit the available ambient air flow/velocity to the radiator or other heat exchangers behind the intercooler. From experience, Garrett and Bell cores weld nicely

It is my understanding that it was originally built by LS1Speed/SpeedInc using a Bell core. I believe that they use a similar sized one on their twin turbo Fbody shop car. A guy from BMR bought it to use in an FBody build but then he changed directions and decided to build a vette instead. Obviously there is nowhere to hide it in a vette so I snagged it from the LS1tech classifieds NIB for $500. There are deals out there. You just have to be patient. You can't build this thing for $500. I believe the core alone costs more than that.

well its not just the pride it also has to do with starting up my own business.. ive done alot of welding for a few people and they were very happy with me and my work... lets just say if they need the fabrication and welding i get the call over many companys that are local by me... i enjoy doing this type of stuff and would love to make it a career... so this car is pretty much a my movin bill board for my fabrication and welding...
