This intercooler OK? CA18DET experts wanted
For my CA18DET setup. I am thinking that my old one is too restrictive. I'm running 2.25" pipes from the turbo and into the TB. I get no
lag now (thankfully). This one has 3" inlet and outlet pipes, but otherwise looks like it would fit perfectly in front of my rad, without taking
too much room.

The price is competitive with what I can find from the States.
My gut feeling is that this will unleash my engine, and allow me to win every single competition I enter next year. I might not be living in reality
however. Ideas please! Tx.

You don't find it a bit Odd? that it Does Not state the most important info: CFM at specific psi points.

Before spending on a new intercooler why not check head loss in exiting one - tap inlet and outlet tubes and put in loop of cheap plastic tubing led
to cockpit - put a 2' loop half filled with coloured water on board with ruler - go for drive, choose safe place in 2nd gear and floor it - get
passenger to check difference in levels - anything more than an inch or three might be cause for concern.
Oh - keep a kink in it to stop vacuum from sucking water out until you get into boost territory.

Yeah, thanks for that. I am gathering it won't matter. Much appreciated.

I doubt any cheap intercoolers will have brilliant pressure balance tbh. Bigger pipework will give less lag. Then its a case of picking the smallest
cooler with the best flow that will keep things coolest. Obviously there are other variables too but this is what i work too.

I am struggling to think of what I may have done to incur such wee taking. If you can't be nice, bleep off. Bleep was not my first choice of
word there.

Problem is there's no info on what you have now, what your problems are and why you think this would fix it. FWIW I've found many OEM ICs
have very good performance figures, they're just a tad under-sized for heavy use. Have you logged manifold temps?
Be wary - larger pipework creates lower friction losses but can add lag due to the turbo having to compress a larger volume to get manifold pressure
up. There's a whole bunch of current system questions that need answering before you identify what might unleash your engine, or even if it has
anything else to unleash.

I don't know. As a foreigner on here, some things may not translate correctly; yes, English is my first language. I am a bit sensitive to these
things, perhaps too much so. HUMAN RIGHTS, HUMAN RIGHTS! I could not have gotten this far with my car without LCB, I do know that, and I am on the
road thanks to many many people on here. I do appreciate the honest approach to this question given by mr Coyoteboy though.
I am of the belief that my old IC is restricting things too much (the piping itself is a hodgepodge that kind of has to be seen); soon as you see it,
you'll understand.

sorry - btw these pics are too big to post here directly
you can see the IC down on the right:

I've re-read all the above posts a number of times and can't see anything to get upset/offended about. 
As for the 1st pic.... should your engine be that furry?

I think some of the posts have been snipped and changed since. I'm sure no-one here meant to be unpleasant but it does sometimes come across
that way by mistake.

LOL, I just nearly died laughing. Beautiful mis-link!

Too many 90's is indeed an issue, and while increasing diam would decrease this somewhat, it would increase lag somewhat. It'd be quite
hard to specify by how much though. I too would suggest getting a differential pressure measurement in there and a manifold temp measurement too.
Can't tell what core you have though. Keep the info coming, but ultimately sometimes it's a "give it a go" answer, which can
be expensive.

Pretty much everything with a CA18DET is in the league of the latter, unfortunately. It is nickel and diming me to death, but what the hey as they
say; what else is there to do in the winter? don't say skiing...

Snow boarding? 
If you want a cheap intercooler, you can always look at other cars with a bigger airflow requirement (IE anything over 1.8L in size with an
intercooler, maybe a diesel?).
Barring that, if you want a project (and can weld), why not make one yourself? That way you could size it perfectly to your needs.
However as has been said before, intercooler size (and piping in general) is something of a balancing act between gas flow speeds, pressure losses
and several other factors, so +1 on measuring the existing head loss as a reference point
If disfunction is a function, then I must be some kind of genius.
