EGR/Butterfly Mod Super Thread

[jap55s]

Done this mod. Don't feel the difference at all

must not have done this correctly, not having a go at your mechanical skills, just saying, i noticed shit loads of difference,
ie: no black smoke on take off, no bogging down, better faster response, better acceleration, the temp needle is cooler by about 2 mm. just under halfway now.

I never had any of those issues to start... Haha it's as basic as they come but I just haven't noticed a difference. Already got yd25 snorkel and no exahaust so that might be why

Hey guys. Started to do the egr and the first bolt decided to snap in half when I was loosening it. Any ideas of how to get the rest of the bolt out?

 

[jjohn]

Has it snapped off clean or is there some left protruding from the housing? If so you might get it with a good vice grip. Other wise an easy out, may be the answer. You punch the centre and drill it according to the size of the easy out.

 

[nathanm_89]

Thanks for your reply. Nah not protruding, snapped half way down the bolt. What is an easy out? Man that sounded like a dumb question. Was guessing drilling was going to be an option. Was hoping there was another way.

Broken Bolt Removal from Engine Block - YouTube

This might give you an idea.

Good find Joe, couldn't explain it better.

 

[nathanm_89]

Thanks guys. That video explains alot. Will give it a go.

 

[jjohn]

Video seems good, anything your not sure, just ask eh.

 

[joe2006]

To be honest, I only watched about the first 5 seconds. This computer is buggered & the videos spend much more time buffering than playing. Hope the bolt comes out ok for you Nathan.

How much extra spool sound are people getting with this mod? I get noise from about 600rpm through till 2000rpm and then it is quiet.

Cheers for your help

I plan on doing this mod soon. And seeing as I cant quite justify the cost of tools i would need / not need but would 100% buy for the froth factor, i decided to purchase a plate from a bloke in the UK. Got it from here if anyone is in a similar boat to me.

I just got a plate from this bloke. So cheap, not worth my time making one. Will be fitting it in the next few days.

Did this mod just yesterday, and Yeah a slight power increase at low revs, but I think the real benefit is not putting that crap through the air intake.
Tip – the vac lines attached to the T-pieces are very tight (maybe even glued) I had to cut them off, but there is enough slack in the other lines to replace them.
Stop putting it off like I did for years and just do it.

no worries...not like the tools would cost heaps. And im sure i would have use of them eventually, but $11 delivered for the exact part i need....done deal in my book.

Just did mine then...took 30 mins max. Better acceleration and better take off from first and second. Definitely better roll on speed from low km/h in 3rd and 4th. Just need to see how the fuel economy goes i guess.
