R32 Constant Misfire, Sounds Ugly As Balls

Ok so I'm having a few problems with my 32 (turbo) I bought the car about a month ago, all seemed fine on purchase, besides bulk unburnt fuel. I did a service myself (spark plugs, oil etc) and at the same time before I went for a drive I bumped up my fuel pressure reg from 20 to about 40. Started it up it sounded like aids, real gluggy and wobbly on acceleration, was told it was a misfire, and perhaps I've drowned my injectors with fuel due to bumping up the fuel reg, or it's a spark plug issue.. I turned my fuel reg back down and it's made no difference. I have 440cc injectors, yellow jacket coil packs and iridium spark plugs. Any help on what the problems are and how to fix would be very appreciated. Thanks guys.

What ecu?

why are you just messing with the fuel pressure randomly?

You can't drown injectors, you can flood the 3ngine and or foul plugs.

In summary your problems are you are doing random things with no clue and that will never work out well for you.

So don't randomly mess with it.

Either spend ages reading and learning, or take it somewhere and get them to see what's going on.

For the time being busy yourself by doing a pressure test to see how many boost leaks you have. Search how to do it.

If you are in NSW, anywhere between Sydney or the Gong, I can have a quick sticky beak for you.

or if you can elaborate on 'highly modified' to get an idea of what the tune should be like I can help.

      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
