OK, fine... It was pretty pricey though...


3" in/out. 4" Core. Pretty nice unit, other than the mounts being slightly narrower its the same dimensions as the VS Racing china unit however a much nicer piece... Another use for my handy dual tape measures coming up!

Mocked up and ready for some weldifacation...
I shouldn't have to mod the header panel and I am working on some rubber seals to seal it into the rad hole better seeing as I know a guy blowing fire with his IC setup... Might have to do some slight mods to the intake plumbing but not more than an hour or two of work.

So I might have been asleep at the wheel

But why the IC upgrade? Feel you are at the limit of the existing one?

I wasn't going to, but the 3" is going to limit me eventually and I don't want to revisit stuff. I kinda wanted data from the 3" as I have MAP and MAT sensors in front of it but I also want to be static for a while.

So for a reasonable "Pre-Covid" price I got the Mishimoto unit and I am going to put it in and put the front end together for good. Or for the foreseeable future anyway.

Yeah, I would definitely put a 4" outlet on that thing. I've been shopping for silly sized cores so I could make end tanks for.

Thats a good idea, I wanna see what I have for IC pressure drop before I make changes. I have REALLY short cold ducting so I am hoping its not a problem....
 
Short update!

I didn't take a lot of pictures but I fabbed up some brackets together with some aluminum stock I had. I kinda hacked up my old metal brackets and I wasnt super happy with them so we started over.

Here is the 4" intercooler in place, nothing too fancy but it works. Bottom bracket is 5mm aluminum angle and is pretty solid.

Mocked up with intake plumbing, which I realized that I now completely had to re-do since I shortened up the brackets.

Backside pic so you can see that my IC is completely within the opening for the rad. Should make for decent airflow.

I Cut, refit and ended up running to the local speed shop for a 3" 90 elbow as the previous mess leftover 45s welded together was sloppy and I didn't like the fit. I might change this later to a piece of straight to take out the 22 degree bend before the intake elbow, then put a hard 90 and into a reducer straight onto the TB. or Maybe 4"? But for now this will work.

The rad went back in for mock up and clearance fitting, some things to attend to here but.... Ok....
20210808_181205.jpg

Going to have to build a bend for the air filter, it doesn't like the Rad inlet elbow... Will revisit that later too....

Put the bumper and front clip back on, did some flow checking of the mods from the previous owner. seems I have good enough front air flow into the IC. I will probably make some rubber air deflectors above the IC to maximize airflow through the IC, but I am going to try it out as is first. I have a pressure and IAT sensor pre/post IC so I can see how efficient it is, because data....

So the front end is now back together, light wiring connected, rad is in and everything fits pretty good. Now for the rear bumper, then finish plumbing routing and get on the inside for wiring and dash install.

Dang - hook up a battery and turn the key.

Looks great Duke - well done!!
 
Ducting. Ducting. Ducting.
Got some aluminum sheet for a deflector underneath. I kinda want to see what works and what doesn't. I have the capability to datalog so much I should probably do it.
 
Going to make it to the track this year yet?

Nice progress!
