.63 or .82 gt3071 with e85 and plenty of boost should come about as close as your gonna get to your goal.

or if your happy to go crazy with boost (and not worried about turbo life and heat etc) you could try a large rear housed gtx28 of some sort

I did actually have teh GTX28's in mind for the 1J, cant help but think the turbine side will be too small for the 3L

But I am now looking at those options, Cheers

Fuel economy and E85 dont mix :)

I did 180kms on the weekend and used 40L lol

Ive done 280ks to 40oddL of 98 and the car is standard lol

I have no updates. But 3.0L related

Has anyone seen either a td06-20g or any other smallish turbo on a twincam 30? I have seen a few gt3076's done

Or if you had a choice the best super responsive circa 300rwkw turbo

I'm thinking I want 20+ psi at 3000 rpm and mega midrange

I'm planning on slapping together a 25/30 for round 2 on the 14th of July and i'll be running a TD06-20g High mount.....

I shall inform you of how it goes!

You can use this one:

But ideally you want one a tiny bit shorter as once you deck the head and block and the belt stretches a bit it gets real close....

Much better off relocating the drivers side tensioner, just wait until you have a belt so you can figure out exactly where to put it as the dimensions in the PDF don't always work.

I used the measurements in the PDF with the above belt and it didnt work, couldn't get the belt on but it was close. Probably just needs to be moved to the right 5-10mm. No set measurements are garunteed to be perfect as theres too many variables.

here is what i do at work;

i grind the head & block

i put the cams in

i put the crank in

i put a thick rag on the deck

i put the head on

i put on all the timing gear

i put bearing blue on bottom of stud,

i then line up tensioner to where its best suited

i then drill and tap the M10x 1.5 thread

Started getting things together to get my dirty thirty project started. Funds are an issue for me so may take longer than u guys lol. But I don't wanna take short cuts so a bit longer without will be worth the wait. Picked up a complete rb30 out of an r31 couple weeks ago for a hundred bucks and a case. Planning on getting an engine stand soon and stripping it down. Then finding a r33 25 head as I want it built out of car to be slotted into daily when complete. So much info! Been reading for the past 2 weeks and printing shit off. Gerg, looking at bringing block, head and other bits and pieces down down to you if ur in Moorebank cause its around the corner from me. A while off though lol.

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
