Exhaust

Extractors - People have had good results with Coby extractors, order from www.partsco.com. I use these - they give the engine a much fatter midrange, making the car a lot more fun to drive. They suit both RB20 & 25. Some power gains might be had with the RB25 by using larger diameter piping for the extractors than the Coby extractors (65mm)

Off the extractors 2.5" is the largest diameter piping you should use for RB25DE. Quieten the exhaust with resonators if its too droney.

THAT was in the sticky right up at the top!

i myself have a set of coby extractors.. changed the outlet to a 2 1/2 inch (50mm would be a bit small for an RB25DE), runing a cat and 2 straight through mufflers (not resonators) and although the car is a fair bit louder than stock. it is not droany..

so you would have to get the extractors modified (it does not come with a flange anyhow)

i got mine from advan performance.. cant remember the price. the guy mentioned that HKS make a set of extractors but the cost is going to be more than it is worth..

ok they replied and the price for the RAGE extractors are $269 +110 or 70 for postage to australia depending if its express or not.

Im not sure if this is nzd or aud. Is there a difference?

Anyone had experience with these extractors anyway?

I was just thinking that, if they are the same size then I cannot see much difference

with extra power...

Unless they are like titanium (weight reduction?) then again they wudnt be THAT heavy,

as opposed to say a full exhaust

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
