Okay, I tried to use the search, but I kept getting "page can not be displayed" message.
Here's the problem I have a Stage II Hahn kit with the FMIC for the 420A aplication. I have cut the bumper as the direction said and I still can not fit the bumper on over the intercooler. The problem seems to be with the intercooler piping being in the way of the slot (drivers side) where the bumper slides in.
Has anyone esle run into this? It is my belief that Hahn, for liability issues, says that it will fit but it actually won't.
Also I was wondering what clutch most of you 2gnt turboed are using and what you might recommend? I have had trouble finding a good one for the non-turboed (420A) 95-99 eclipse.
All comments are welcomed. Thanks.

Ive heard some guys using the SPEC clutch along with the clutchmasters. I believe you should stay away from the centerforce dual frictions according to what ive read



"Who needs a 4G63? I'd rather walk the competition than my crank..."

- Bill Hahn.... 420a GOD :bowdown

dual friction sucks! dont get it. i have it right now on my car and been using it for about 6 months. and it's already worned out. it slips so much

Yeah I've heard the same thing about the dual friction, but I have had trouble finding a good (reputable company) clutch for the 420A application. It seems that there is a huge variety of clutchs for the 4g63 though (what's up with that?).

It sounds like a problem with your piping not the intercooler. Who made your piping?

The piping came with the kit, but even if I was to get different piping or cut it a little different, the outlet & inlet of the intercooler is right next to where the bumper would slide into the frame/body of the car. It appears that I would have to get a custom fabricated bumper to fit around where the IC and the piping meet.

Note that the first picture is from a 4g63 not 420a, but if you notice on the bottom right of the picture where the piping and IC meet... this is where I'm am running into problems.

this is how i cut my bumper support to fit the piping...



a little work, but it fit.

Thanks, but your picture doesn't seem to be displaying for some reason.

Did you cut off the metal prongs/arms that slide into the frame of the car?

We use the HRC front mounts on our Avenger kits. The front supports are the same. The upper pipe should come out and shoot right in the middle of the outer bumper support, letting the 5 mph bumper slide over it. Then the front bumper over that.

Can you take some picturs of what you are having problems with?

I will try and do that when I get some free time off of work. Do you have any of your pics laying around? Maybe it's something I over looked... but I have had performance shops, friends, etc. look at it and they all just kind of scratch their head the same as me. It would be great if you have the solution!

All I can say is that my Hahn FMIC and supplied piping fit like a dream. (BTW, that isnt a 4G63, it's the V6 from the avenger. Count them, 6, intake runners. ;)) Make sure you have the IC in the right bolt holes and mounted right side up. (rounded side down, flat side up) It took a couple of test fits and trial and error but it works. Trust us. Hahn prides themselves with their kits being a bolt on affair. (Maybe with the exception of their questionable downpipe :P)

"it's the V6 from the avenger". I guess I did miss that... that's what I get for not paying attention to detail.
Sounds like a plan. I will take another look at it next time I have the chance to take it all apart. I did do test fits and all but nobody's perfect. I hope you're right though.

fixed.

I really have to take a picture and show you, but I cut the bumper to fit around the IC. It would fit too, but the prongs that slide into the frame of the vehicle is what is actually getting in the way. It is like the pipes/IC outlet and the prongs meet in the same place (where the opening of the hole where the bumper arm would slide into the body of the car is).

I didn't use the front bumper support. I did have to cut a bit from the center area so that it would not be pushing against the FMIC. Other than that I did not have to do any modifications for it to fit. There is an IC pipe that connects to the FMIC through where the old bumper support mounts to.

Yeah, I forgot to mention that too. I didn't reinstall the 5mph bumper. I was afraid that doing so would let the front clip sag a bit but it mounted (after being cut back an inch all around in the big air dam) right up and looked stock again...minus the intercooler fins. :thumbsup

"Make sure you have the IC in the right bolt holes and mounted right side up. (rounded side down, flat side up)"
I checked on this and the rounded side was down, flat side up, and I am sure that the IC was bolted in the proper holes. I am starting to think that it might some how be the piping. I suspect that Hahn might have sent me what ever piping that they had in stock that they though would still fit fine for my aplication, but it was actually made for a different kit. Or maybe an honest mix up. I guess that it is at least giving me some weight reduction! I am just worried that if I hit something w/ my car that the IC could get damaged beyond repair.

I had to cut into the bumper also. I dont use the 5mph bar either. I had to cut about 1" all around the center opening and cut into the driver side vent hole some to get the pipe to not be pressing into the bumper cover. I actually like how it turns out as you can see my powdercoated piping better!

I did the exact same thing on my 97-99 front but God damn man, good clean cuts. Looks amazing. :thumbsup

most people usually ditch that 5mph bumper when they install a FMIC. usually you hafta hack it so much that it's not going to do very much anyways. unless you need it to pass some kinda inspection or something :shrug

I retained my 5MPH bumper, cut it just like the picture above on a full size band saw!! I too had to cut some material out of the vent on the bumper to get it to fit right, but other than that it bolted right up no problem. Take a picture of the front of your car and take a picture of your piping off the car laying on the ground. We'll be able to tell you quickly whether you have the right stuff. Putting th Hahn FMIC should take 1/2 hour tops.

I appreciate everybodys input! I fell a lot better about not having the 5mph bumper on there now. Weight reduction right!

That thing was heavy. Wish I would have kept it though. Going back to stock and missing lots of stock parts isn't fun.

Bah, just leave the bumper support off.

The bumper cover fits a little better with the support in there, but this hasn't bothered me enough to deal with cutting most of it away to get it to fit.
