been planning this install for a while, finally getting to it. I've seen all these complicated set ups, that seem like a pain in the butt, with tiny intercoolers, or worse the Top mount!

SO I found a FMIC, the "V" mount style, only $80 on ebay! looks pretty decent, and the core size is bigger than a 951, with double the frontal area!
it's core is 23x13, and fits perfectly infront of the Radiator (I have removed the A/C condenser)

Now the only problem I've run into, is seems like Ill have to get rid of the pop-up headlights as the mechanism would hit the IC pipe. OR if you are getting rid of the CIS for EFI, that would eliminate the need for Fixed headlights. (but I have always planned on Fixed headlights anyway so It's not a big deal for me.

Only real mod is punching a couple holes for the IC inlet/outlet you can see it just to the right of the headlight mechanism in the PIC (havent fitted the 90 silicone hose yet)

Note, Ill be going to a 135* silicone hose around the CIS meter.

Also Im using 2.25" diameter tubing, (2.5 is really un-necessary) and the outlets of the IC are 2.5"

The problem of the space between the engine and the radiator is a real one. I failed to put the original cover for toothed belt. I'm talking about stock equipment now.
Trying to add something there is praised!

Try to protect the gas pipes over the IC pipe. The original protection is broken in that area.

ill eventually convert to a larger all Radiator, and Im deflecting the ducting behind the nose vents to go into the IC/rad area.

also will eventually go EFI. Plus I live in CO, so the temps stay fairly cool, won't be driving this on hot days. Additionally I have a manual switch for the second cooling fan.

Looks like a nice IC if you don’t mind loosing your pop up lights..

Rad can be spaced back on the bottom a good 2 inches if you need more room..

Mine has bottom mounts just like yours and I found a good way to mount it solid..

See the spacers between the rad bottom mounts and the rad mounts on the lip, and the piece of angle iron running across, with the bottom of the IC bolted through that angle iron..

Mine is 4.5 inches thick at the tanks with 3” in/out though so you wouldn’t need as much spacer..

The mounting worked out fabulous though..



Mine is EMUSA too, lol.. no problems with mine yet and it’s seen 25..
Also no engine temp problems at all with my stock rad, and I log it so I would know..

Yeah, I did a similar thing as Eddie with mine, spacing (actually leaning) back the radiator to give more room for the 951 IC pipes over the top, so as to keep the headlight linkage... and then a bolt-in piece of 6061 aluminum to reinforce the very hogged-out top rad mounting.

Though I think this kind of IC looks easier and cheaper, possibly more efficient, than the 951 style is these days... probably the smarter way to go now.

Yeah, the 951 IC is ok But more frontal area is better. (plus you dont have to cut up the panel as much.

I guess if i was going to keep both the CIS and the pop-ups it might be an issue, but since i have always planned on getting rid of both i didnt care, and one I get rid of the CIS it will be a straight shot between the turbo and IC. but for the moment I just want to keep the car running, so Ill go around the CIS, it actually fits pretty well if it wasnt for the headlight linkage.
(and lets face it, the stock headlights suck!, I put fixed HID projectors in my 951, way better lighting!)

also I didnt need to move the rad back, with out the condenser it fits just fine.

ok - Thanks. I am very tempted to do the same.

update, started to finish the piping routing

I’ve come to think that turbos flow so much volume (at relatively low pressure) that a cubic foot or so of intake piping and IC internal volume are basically nothing..

What if my IC intake added volume is 20 liters?
That’s 40 engine revolutions on a 2 liter 4 stroke..
3k RPM that’s less than 1 second of flow..

Airplate reaction vs TB seems instantaneous..

BAM: was actually fairly easy.


the IC goes to about the top of the bumper
