Guys, this is good info. I didn't know that the 2UZ heads were that much different from the 1UZ heads. Thanks. It seems to me that the 2JZ ports are nothing to be screaming about. Yes, they work well in their application but they are also designed for compactness (read what Larry has to say...

I forgot which magazine it is, but they do the 0-100-0 mph test, and the Enzo beat 3 other cars in the comparison... I believe they were the Porsche Carrera GT, the Saleen S7, and in dead last, the Mercedes. In a recent Motor Trend (I think it was MT, or it might have been C&D), they were...

Oops. You learn something new every day. At any rate, I just meant to imply that the Northstar is an impressive engine from an engineering perspective. Not to take away from the LS's though. They are very impressive as well. Definitely, without a doubt, the best SBC's ever made.

Right. Well maybe I was being too optimistic. Let's say, 7500 rpm while actually making power that high. That'd be something to see. I'm still not holding my breath though.

I'd actually love to build a 1UZ Supra from an N/A MkIV, but honestly, being currently on Guam, the only place I've been able to shop for prices is ebay. And there's actually no N/A Supras on ebay currently. Even when there was, they were rediculously expensive (thank you TF&TF). It's made me...

Funny, I thought BSFC had more to do with fuel consumption than PSI. How about forgetting the LS7 and the Viper engine, and let's use something with 6-bolt mains... :D Yes, that's right! The Northstar engine! What, you thought I was going to say 1UZ?

Don't forget the Honda V6's that came (still coming? I'm not sure) in some of GM's products, like the Saturn Vue. And anything less than 2L in a GM car is usually a Korean engine (Daewoo). GM has one good point with OHV engines: packaging. It may very well actually contribute to a lower...

Personally, these things have me torn (wrecked exotics, that is). As indifferent as I am to the Enzo (I'd MUCH rather have a nice Zonda or Koenigsegg), it's still an amazing machine and it makes me sad to see one get destroyed. But at the same time, it serves the ass right. This may sound...

Kind of late to this conversation... There's a company named LA Sleeve that makes progressive auto sleeves in a huge number of sizes. You could probably sleeve it to 95+ mm and still have a fairly thick wall sleeve. I've looked into both wet and dry sleeves and wet sleeves don't seem to be...

AH thank you thank you thank you thank you... :D

Honda's K20 engine shows gains when switching from 2.5" piping to 3" piping. I myself figured that 3" was way to big for a naturally-aspirated 2.0L but it has been backed up with proof. Now... I'm fairly sure that cams and a higher rev limit came into play. With a relatively stock setup I...

Good luck man! Look forward to seeing the project. And yes, I do agree that tuning is the most important aspect of the setup.

No guys, sorry but that is wrong. What happens is, there is a passage that allows coolant to bypass the engine. Most people when removing the thermostat improperly leave this passage open when removing the thermostat. This allows the coolant to bypass the block and boom, there you go...

Nice link! I'm not a big fan of the SC430, but that car looks like it'll be pretty cool. It's also rather interesting to see Ford jumping into Super GT.

Yes, sorry for being so abrasive, but I sometimes fly off the handle. In my opinion, 500 whp on the stock block is a no-go. If you are going to push it to prove me wrong, more power to you! :) Just be sure to keep us up with all the juicy details.

Oil-cooled engines have obviously been a reality in past cars such as Porsches and Volkswagons. Now, to simply put oil into the cooling system and run a 1UZ, yeah... I don't think it's a good idea. If the engine were designed around an air-cooled oiling system (remember the typical Porsche...

Pushrod Toyota... interesting! The 3UZ pics... that's an odd intake setup. I know Toyota uses the 3UZ for their SuperGT Supras, but I would've thought they wouldn't have Lexus branding on the engines. However, the Esso logo in the background leads me to believe this is in fact a SuperGT...

90k miles on a 1UZ really is kind of barely scratching the surface. In stock form, the longetivity of these motors is nothing short of amazing. I'd MUCH rather go with a "high" mileage (90k) local motor (after checking it out, of course) than a "low" mileage (40k) ebay motor that you're...

You don't get it, do you "son?" You do realize there's a big difference between iron blocks and aluminum sleeved blocks? Or beefy cast rods versus Honda-sized rods? You know the difference ring spacing can make? Have you looked at the 1UZ pistons? No it's not "ALL about the tuning," if it...

A 6-bolt 4g63 at 500 hp will be more reliable than an internally stock 1UZ at 500 hp, if you can get it to make that much. I've been pushing 20 psi daily on pump gas on my 4g63 for about 20 of the 60 thousand miles on the odometer, never having even cracked the factory head gasket off yet...
