Okay, I'm starting to realize that the 3UZ comes with a lot of things that I want. And I'd rather keep the weight down so I don't want to use the 2UZ. For $100, I'll have a set of 8 4g63 stock rods. All I have to do is get them machined, and get a set of custom pistons, and get the crank...

Good call, I didn't even think about that. Thanks.

I am curious to know whether or not you can modify the VVTi heads to take regular 1UZ cams. Since there isn't anyone making VVTi cams, and it would be somewhat more trouble controlling VVTi with a standalone, I figure the easiest thing to do is to get rid of it. Is this possible?

Yeah, I understand what you guys are saying. Mostly I liked the idea of the 48mm big end since it gives a lot of room to play with the stroke. I'm still looking into the idea, but using the stock crank with stock 4g63 rods. I can get them really cheap and have them modified, but I need to...

Okay, first let me state that this idea certainly won't be for everyone. Also, the reason I'm using this idea is because I'd like to make a high-hp, bigger displacement engine that will make power up to about 9500 rpm. The things that I was concerned with are rod-to-stroke (R/S) ratio, as this...

Chris, I'd like to use a MS on a 1UZ, so I'm very interested to see how yours works out. I had thought the easiest way would probably be wastespark like you said, and I like that idea. As far as transmissions, I'm just concerned that whatever I get can handle the power. I don't think a...

Just to dig this thread up, because I found it interesting, if you have a backround in music or audio study, you may notice what they've done. Basic concept: a low note creates overtones above that note which expand all the way up the musical spectrum til you can't hear them anymore. Yes, even...

Standard journal bearing turbos can take a lot of oil pressure. I feed mine off the outlet of the oil pump. I have a feeling that, were the return at a slight up-angle, I'd still be able to have proper oil flow. Ball bearing CHRA's require LOW oil pressure. On my car, I would use a banjo...

I love the GRM yearly challenges. Those cars never cease to amaze me. I think a lot people that get into cars through their own car are like videogame fanboys. They talk a lot of crap about everything else and only THEIR car or THEIR engine is the best. I think the root cause is that they...

Forget I even mentioned cylinder pressure. Obviously I was confused when I brought that up. Okay, I'm confused. I think I misunderstood you before because I totally agree with that statement. I can't even think of what it was I might have been trying to get at. I totally agree, mass air...

Ugh. I want one. I wonder how much it'd cost to get ahold of one.

Exactly my point. A 1UZ with stock heads isn't going to flow ****, and thus no matter what turbo you stick on it, you're still not flowing **** at 5 psi. Boost is a measure of flow which is NOT entering the engine, so they ARE related. You can't just base everything off the turbo's mass flow...

It looks awesome. I think it's quite an ingenious thing. As for your VVTi, Nissan made SR16VE and SR20VE engines which was basically intake and exhaust cam V-TEC, and the cams actually switched one at a time (exhaust I believe was at like 5200 rpm and intake was like 7000). I've got a video...

No way you're going to split a block at 5 psi. I'd love to see a 1UZ that is breathing so well as to flow massive lbm/min at only 5 psi.

I wouldn't go with JE's... slap slap slap...

Okay, I'll take one. Where do I sign up?

But it seems as though this is a tradeoff with mpg. I mean, the 6.0L LS2 getting 20-some mpg, that's pretty awesome. I don't think the issue with bottom-end on DOHC is due to cams or displacement, I think it is due to the 4-valves per cylinder. If there was a cam that would only open 1 of 2...

Do these rods require the crank to be machined? I'm looking for a rod and piston setup that won't require machining the crank. Though if I have to, I suppose a knife edging and micropolishing would be in order. :)

You can hear the lag in the videos. Most of the cars in the videos are big, 5.7L engines. I wonder why they haven't made any 4-cylinder kits yet? Turbines work off both differential pressure AND temperature. Change one and you are probably changing the other. So not only is there less...

Not to mention, you also get more flow area with less valve shrouding on a 4-valve head than a 2-valve head. The only real downside to DOHC (aside from double the valvetrain parts, in other words, $$$) is the timing belt/gear/chain setup, due to the fact that it has to be much larger.
