Greddy intercoolers type 24 or 31?
Hey guys, I'm soon to purchase a full greddy TD05H-18G turbo kit and I am just debating on which intercooler to get. I have a 99 civic si and I plan to use my stock front bumper.
If I get the type 24 I think some of the rows of fins may be restricted by the bumper...would this cause a problem?
The type 31 fits in better, but i'm under the assumption that bigger is better?
Will the type 24 produce more power than the 31 would?
I plan to run about 8psi boost for now, but I may go more later on down the road. Any suggestions on which intercooler I should get? Any input would be appreciated. Thanks.
forgot to mention sizes....
type 24 = 23.6"x11"x3"
type 31 = 23.6"x7.6"x3"

Tall and thick mean ten times more than width. Temp drop takes place best when there is the biggest difference between charge and core... with an IC with a lot of width, the majority of the IC, past the first 5-8 inches, acts like a heat sink for the rest and doesn't do a whole lot to cool the charge.

The type 31 fits perfect without much modification to the stock bumper reinforcement. If you get the type 24 you will have to cut away at the reinforcement to make it fit. If you don't plan on making anymore than 350hp the type 31 should be fine.

Even if I don't plan on going over 350hp for now do you think the type 24 will add more power and keep the air cooler? or do you think it would be too big to bother with for my low boost.

I'm not sure how much of a difference the 24 makes at lower boost levels but if you have the extra money and don't mind cutting up your reinforcement by all means go with the Type 24. Just keep in mind its about $200 more than the 31 so if you don't ever plan on making beyond 350hp that $200 can be spent on something else. Check out the search feature because I have seen a number of topics covering the exact same subject. THat should give you your answers.

bigger doesnt equal better for IC's. You want one that is well matched... too big increases spool time on the turbo

Yes, but by how much?
I was dealing with a 24"X11"X4" IC, that's over a thousand cubic inches of volume, easily half again the volume of your average big power street Honda. and I was spooling at 3000 rpms with .60T3 with .63 AR turbine... a full 600 rpms higher than I was spooling non-IC off a .50 T3 with .48 AR turbine. Can you say in-*******-significant?
A great body of word-of-mouth wisdom is passed about, and following it for the most part results in a large amount of success, but if you ever want to do anything beyond the norm you have to 1) think and 2) try. There's a lot of incorrect or unsubstantiated "tech" floating around on the web. IC's of certain dimensions, core design, etc, have a larger effect than mere volume or size would indicate.-
Not a personal attack - just a point of view.

I thought it decreases spool time due to the volume inside the intercooler. Like having no intercooler and running it straight to the manifold......no interference.

. 24 is overkill for you setup. I guess I should say IMO
