DIY: Berk Technology HFC Install

bplourde · 10-02-2010, 08:21 AM

I have a Stillen G3 intake installed--will I need to disconnect it from the throttle body the same way people have to with the stock intake?

Haha the only thing I broke was a cat! All the tools survived, even my knuckles.

(stripped the driver side bolt so this was the only way...)

I read the thread, but maybe I missed it.

I see you weighed the stock cats in your pics. How much weight savings are we talking? 4 oz?

Berk Technology HFCs are 5 lbs. lighter each than stock so 10 lbs. weight savings total.

Your dyno pics (Last one) shows a gain of 24whp/26wtq. What else was done to acheive this (Uprev/tune/CBE/etc.)??

How much would I expect to gain from simply installing Berks on my NISMO? What about with Berks & Uprev tune? I'd like to keep the OEM NISMO exhaust.

The dyno was 100% stock vs. 100% stock w/Berk HFCs, nothing else done to the car. They might not gain as much on the Nismo since the Nismo cat-back is better than the regular stock cat-back, but you should see good gains. Essentially, the first mod you do to the exhaust system on these cars will show the biggest gains.

Now that's what I call going bat$hit crazy with an uncooperative car part. My friend, you rock!

What about applying anti sieze goop in the event you need to remove stuff down the road?
Recommended or not necessary?

arghh!! did anyone have trouble with the bolts connecting the cat to the H pipe? i cannot for the life of me get the outside bolts off on both the driver and passenger side. cant get a breaker bar underneath the car either.

PB blaster,then put a closed end wrench and hit the wrench with a hammer to start it.

bah...now to figure out how to get a wrench into the top 3 bolts!

christian370z · 11-21-2010, 11:22 PM

I used this method to daisy chain two wrenches together to a) get enough torque on those bolts and b) to reach them:

You can also access that bottom bolt facing away from you by using an extension and sticking through the subframe in front of the camera. There is an opening, you just having to play around and find it since I can't remember exactly where it is.

Before i put my new exhaust on i pulled off my HFC's to install the gaskets between the cats and the stock exhaust mani's... i got them off without having to go through the engine bay. 2 of the 3 bolts on each side i got off using an 2 open end wrenches like the above pic and the other 2 i got off with a impact gun, 14" of extensions, and a universal joint. **** was too easy. But, that was the second time they have been off the car. Not sure if it can be done that way with the stock cats.
