18" long core, 12" tall, 3" core thickness, 2.5" in/out - the DIY FAQ says 20" core is the optimal size so this seems like a pretty decent... let me know what you guys think. I'm going to purchase it tonight unless anyone says they think it's a bad idea. Greddy turbo kit, aiming to run 180 whp, but I'd like the cooling capability for around 220 whp.

I believe that is what Brain just bought. It looks like a good IC.

 

Sounds like a winner to me. I'll be running the same or a little larger if it will fit. I belive I've seen a 22x12x3 somewhere and it *might* fit on my 99 with some massaging.

 

brains is longer. The 18x12x3 is what I have, works great and fits good. It looks alittle small, but gets the job done!

 

You have the 18" overall length correct? The OP stated 18" core. So I took that to mean his overall length is longer than 18" which is what Brain just installed.

 

KEYWORD = CORE


my core is 18x12x3.....it's probably a +500BHP IC, it would be perfect acceptable being only 18x6x3, but it fits, so whatever.


the 11x12x3 core IC that a lot of you are rocking is perfectly fine for under 300rwhp.


these two have been discussed in full again and again.
