2J all the way....all the way!!

if you want a v8.. why not just get a soarer??

it may have an extra 25% capacity but hes put in a heavier engine, in an already nose heavy car, and put the turbo right up the front... on the wrong side of the front wheels.. and thats not a small/light turbo either... imagine the amount of understeer it would have over a 2j with the same turbo.. not to mention the heat soak into the radiator from the exhaust being right there... thats got to rob power aswell.

is there any real benefit in overall performance by spending the money on doing this?? i think not.

the Jun supra dont need no mongrel v8 conversion.

are you sure the 1uz weighs more than the 2j NZM.031?

on a few toyota sites, they say that a bare 2j is about 181kg and a bare 1uz is about 175kg.

its not much in the sceme of things, but it certainly isnt a heavier engine from the looks of things.

also its inherantly a shorter engine being only 4 cyls long instead of 6, so it would have a more centralised weight distribution

Good point^

Yes, the 1UZ is probably shorter and lighter anyway...but really...any difference between the two engines is going to have somewhat negligible effects on weight distribution given the Supra weighs around 1600kg in the first place. Regardless, what's to say this isn't a car that has been set up for straight line heroics? In which case I would undoubtedly take the 1UZ over a 2JZ. 2JZ has a solid reputation for withstanding immense power in factory form, moreso than the 1UZ. But when you throw limitless amounts of money at either (stroking, forging etc.)...the 1UZ will come out on top because it has more displacement...for which there is no replacement.

Let's also get our mathematics correct and state that this engine has a 33.3% increase in capacity over the 2JZ...

If you've driven a car with a 1UZ you will know how smooth and refined these engines are, noticeably much more than the JZ series. This conversion makes sense to me...if not to give this car a much better sound, then to make it a smooth cruiser or an absolute animal in almost any situation with an even spread of torque across the range.

well im not sure now that you say that... i suppose the 1uz is all alloy vs cast block of 2j.. it would also be shorter in height, meaning it wouldnt throw around as much side to side force as the high straight 6.. i can see some merit to it in terms of why the jgtc cars run v8s... but for a street application thats not very well thought out in terms of heat and turbo placement, i cant see the point... and to ask $45000 is a bit much.. considering you can pretty much bolt that turbo to a stock 2jz bottom end.. leaving you enough change to buy some decent wheels (not saying gtr wheels arent decent) and the 2jz looks so much smoother and tidier in the supra engine bay than the 1uz.

for the same price (nearly) you could buy twoogle.. hmmm... v8 supra or twoogle??

    • Ok i will get those 310mm. I found one but on a different site. This is the description on those...is it ok? Technical parameters: - Axle: front. - Disc type: ventilated. - Number of holes: 5. - Disc diameter: 310mm. - Total height with center: 54mm. - Thickness (new/min.): 30/28mm. - Designed for brake calipers manufacturer: Sumitomo.
    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
