Ha never thought of that, Ill hit you up in a week. :) any engine bay pics? , sounds pretty sexual .

Will do after the weekend. I would have gone the Jun route, but i had a Greddy style and nothing to do with it (was initially for an S13 with an RB30DET, as the stock plenum didnt clear the bonnet, but went R32 head instead).

Mine was <$500 for the plenum and 80mm billet TB, almost half what the JUN style inc TB's cost, not sure how much performance difference there would be, but the JUN is definately more ideally suited for N/A due to the bellmouth's, longer and identical length intake runners.

I had a look on a plenum calculator, and for peak volumetric efficiency at 6000rpm i need 12" intake runners with a 2" diameter - somthing ill make at somepoint, until then the greddy should keep me happy. Mainly wanted it for the larger TB, and to get the intake away from the hotside of the engine, as well as the benefit from a much shorter intake pipe to CAI. Not sure what it will do for VE gain, as i think the runners may be too short, time will tell :blink:.

ECU is microtech LT12S, GTR loom, 550cc injectors (low duty cycle for better efficiency taking advantage of the sequential injection) fujitsumoto jasma tuned length extractors, 3" mandrel exhaust (1 centre offset mandrel glass packed perforated muffler, straight through resonator, no cat) 1.5mm gap 7 heat range plugs, upgraded coilpacks, 255, 8.3deg cams & >11.5:1 compression ratio.

once its together, should be quite angry. Had this in the works for a while, but i got distracted with yet another car (30e+t) made some big numbers with it, got bored, its done now so i'm back to my N/A ways on this old project.

      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
