failed HFC install

Red370 · 03-16-2010, 11:10 PM

yeah, me and the OP tried unsuccessfully this past weekend, so they made more progress than we did at the hobby shop, but damn Steve, this was a total downer, i wanted to hear that thing. Did they use any PB breakfree?

yea they soaked it good and they used all good quality tools and spent about 2+ hrs trying.

Is it just one bolt on the stock cats that make it a PITA? Sorry to hear, try taking a flame to it if you can get in there.

Red370 · 03-16-2010, 11:35 PM

almost like Nissan intentionally did something to prevent that one from coming out

soCo · 03-16-2010, 11:56 PM

I just looked at the DIY, looks like the first 5 steps take about a half an hour. The 6th step, with the bolts your talking about looks like it takes up the rest of the time.

These guys didnt seem to want to try the torch thing so I will find a shop that will do it and see how it goes. But Im nor trying to spend too much for a few HP.

First lots of anti-seize.

Then get a torch in there, heat up the hell out of the metal around the screw to get it to expand and then remove the screw.

Its interesting that shops can "fail" at installing things. Seems like they need to fix your car now for free because they couldnt remove a screw without stripping it.

I thought about that but since they were not sure about the torch thing and all, I was thinking so do I really want them trying stuff they arent comfortable doing. I will probably try another shop and if they cant get it I will just not do the HFCs. Im hoping the Cobb will still net me some good gains without the HFC, and just my CBE and intake filters. Im hoping adjusting the timing and A/F will net me the most.

I had this exact same issue when installing my HFC's. I will be posting an install thread with my thoughts from the past month of having gen 3's, berk HFC, and Stillen CBE. As well as the pics of the stripped bolt. It was a PITA and took over an hour just to remove both HFC's due to those stubborn top bolts. I haven't read the whole thread but i hope you find a solution soon.

Don't give up brother.... the HFC is worth it!!

Zsteve · 03-17-2010, 02:33 PM

thanks, what did u do to get the stripped bolt?

Mike · 03-18-2010, 09:41 AM

It took the guys at Forged 3 hours to get my test pipes installed because of that stupid bolt, and the car was still brand new!

I've found so many places where they Gorilla Torqued fasteners on this car..
Either the torque specs are way out of line, or the production torque wrenches are way out of calibration. We just had to replace a short hardline on the rear caliper on Zpirates car while putting stainless lines on due to extreme torque used on the part into the OEM brake line Block...

evse82 · 03-18-2010, 05:11 PM

Use the threaded bolt unfastners to get it off. They are sockets with a swivelled thread that digs into the bolts head and takes them off. I used one on a door bolt once on a mates car that was completely round and it came out first shot....

Also installing my HFC's and exhaust took about 3 hours. (the exhaust was like 25 minutes - that bolt was like 2 hours lol)

NYBladeZ · 03-18-2010, 05:31 PM

My mechanic heated the flange up until it looked cherry red and then the bolt gave away
