Keith C Posted July 18, 2003 Share Posted July 18, 2003 I'm full of questions today. Well, full of something... Anyway - I *know* my EGR is leaking. As I see it, I have two options: 1) Attempt to fix it 2) Disable it If I go for 1, which is the bit most likely to *be* leaking? If I go for 2, do I have to go for the single or twin plate removal? I'm not bothered about physically removing the whole setup, but I would like it to stop leaking. Also, what are the pros/cons of disabling it?

Guest Martin F Posted July 18, 2003 Share Posted July 18, 2003 Have you checked the hoses around the EGR ? They are the most likely culprits for leaks. I can't remember the advantages of the twin plate removal over the single, but suffice to say the lower one is a bitch to fit with engine and manifold all in place. Pro's - lower inlet temps on cylinders no5 & 6 when on light throttle, and also less chance of an inlet leak Cons - Higher emissions. Link to comment Share on other sites More sharing options...
Keith C Posted July 18, 2003 Author Share Posted July 18, 2003 Hmm, think I'll try fixing it first. Supraforums indicates it could be the easiest to get to hose, so I'll buy a length of hose and swap them all until it goes away, and if it doesn't, I'll remove the whole damn thing Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 18, 2003 Share Posted July 18, 2003 Remove all the gubbins and blank the bugger off, they are a PITA and purely for emissions purposes, and I KNOW that won't be high on your list of desirable features Link to comment Share on other sites More sharing options...
MONKEYmark Posted July 18, 2003 Share Posted July 18, 2003 off powerhouse racing site. there does not look much to them. something you could make for not much??? PHR EGR Block Off Plates. The factory EGR system was designed to assist in emissions reduction by allowing hot exhaust gases to be recirculated into the cool incoming air within the intake manifold. While this was a great idea from an emissions standpoint, it has horrible effects on a turbocharged vehicle that relies on cool charge air temperatures to make horsepower. Even removing the vacuum hose from the EGR valve does not stop this process, as exhaust backpressure still manages to open the valve under boost. Stop these hot gasses from ruining your cool air the right way, by installing a pair of PHR EGR block-off plates! Machined from 1/8” 6061 Aluminum and hand-polished for a show-quality appearance. Accept no cheap imitations cut from thin material that warps and leaks, go with the best! Highly recommended! Price: $90.00 pair.

Chris Wilson Posted July 18, 2003 Share Posted July 18, 2003 If you can post a link to the site and parts illustrations I'll weigh up how much i could sell a small batch for. Cheers. Link to comment Share on other sites More sharing options...

Branners Posted July 19, 2003 Share Posted July 19, 2003 Andrew Dunk Shaw has my EGR blanking plates at the moment and was looking to copy them, but needed to know there would be enough interest in a batch of them. I believe they retail for £40 from the US, Andrew was talking about £20 to £25 for his versions. JB Link to comment Share on other sites More sharing options...
blancovich Posted April 25, 2005 Share Posted April 25, 2005 here you go http://www.powerhouseracing.com/supratt_othereng.shtml could you post he link again? I am trying to install my EGR blockof plates but don't know enough about the car to remove them easily. pics and instructions or the splace where I could get them thanks!!!!

Chris Wilson Posted April 25, 2005 Share Posted April 25, 2005 I do a laser cut, hard anodized pair of plates for £35 quid the pair, no VAT to pay, P&P 2 quid See Pics Here These plates ahve a removeable blanking screw to fit UK and US systems. I actually sell the things to the Yanks... In stock now, quantity discount. Link to comment Share on other sites More sharing options...

If you guys want a few sets of EGR plates, let me know and we'll do a group buy for far less than retail. There have been countless copies of this design, and although its easy to copy and make up, still in bad taste to actually openly use our pics for such a purpose IMO.

This was a year ago. dont think a group buy will get much interest over here as most cars are jap imports and dont have the EGR anyways.

I don't. It's a bit of metal (hardly some complex design we're copying here), if someone can make them cheaper for us then I'm all for it. Link to comment Share on other sites More sharing options...

Digsy Posted May 11, 2006 Share Posted May 11, 2006 You can do "internal EGR" with a VVTi engine. You may be running EGR and not even know about it Link to comment Share on other sites More sharing options...

I dont necessarily have an issue with anyone copying them, its been done 100 times already in the US. I just had an issue with quoting text and pictures directly from the PHR website to aid in the copying. Its all good mate.. Link to comment Share on other sites More sharing options...

Well, it slows the combustion process down to limit the production of NOx emissions, so I can see the logic in that. Actually, to run fully internal EGR I think you need a phaser unit on the exhaust cam rather than the intake (or as well as the intake). The VVTi is of course intake phaser only.
