Just bought a SC400 yesterday as a daily... did I make the right choice?

true, price is higher up than SC series.

They are actually pretty similar, barring that you could actually get cloth seats in the JDM soarers.

What really set them apart was;

a) They were available with a 2.5 Twin Tubro 1JZ in addition to the 3.0 NA 2JZ
b) You could actually get that version with a manual transmission

and for the gravy

c) Some of the UZ soarers were actually available with an active suspension (yeah, Toyota did it before Benz and pretty much anyone else). It is however, even rarer than the manual tranny soarers.

...don't forget the single turbo VVT-i 1JZ Soarer. Ultimate sport version, IMO.

However you have the 1UZFE, not really that much heavier than a 2JZ, I think (aluminum block goodness). A motor that is starting to make its way into both Mk3 and Mk4 Supras. Sometimes even twin turbo'd. The early 1UZ's are supposed to be majorly over-built (6 bolt mains and 4 bolt rods), but I don't know the year cut-off. Later are supposed to be a bit weaker. So you've already got the motor... and 4.0L can spool a lot of turbo quickly...

As for the auto, I'm 75% sure that it is the same as the Mk4 TT's auto, which there are upgrades for, which would be less of a headache than a manual swap. Firm the shifts up a bit.

How much more was the S2K w/insurance compared to the SC? You can hook up an SC but curious as to why you went that route.

huh, so the early 1uz's are better for boost applications? i know later uz's in the US from 98 on had dual VVTi and were rated at 290hp, 40hp higher than the early ones.

the s2k was a 05 and was financed. i was paying 280 a month plus 200 insurance. not a lot, but i got a lot of bills and they add up. austerity is the new black, lol. SC was a 92 with 130k miles so it was cheap enough that i could pay cash. looking forward to not having to make payments.

All 1JZ cars switched from twin turbos over to single turbo VVT-i in 1996 or so. I really don't bother to mention it, as it is an update/evolution rather than a different model. Good that you brought it up none the less.

The UZ is all alloy, and actually far lighter than the JZ. In fact, it is around the same weight of a 3S-GTE (Slightly heavier IIRC).

It is in fact majorly overbuilt. I've been telling guys for years that the UZ is essentially a 4.0 V8 JZ engine. 6 bolt mains, forged crank, very robust. Guys in Australia have boosted them to around 800hp on the stock block. The weak point are the rods, they are thinnish and not forged, but they can still take a lot. I plan to do a lot of work with this engine whenever my shop opens. They are great for NA applications too, as I'm pretty sure Ive seen guys with over 500whp NA.

Can't remember the differences in the bottom end between no vvt-i and vvti 1UZs (if they are any), but the 3UZ has thinner weaker rods and less bore space between the cylinders.



Guys, These engines are based on race engine architecture and have been used modified in racing applications from GT500 to Daytona prototypes. Awesome bit of kit.

lol you guys are starting to make me wanna mod this thing! but if i go crazy and mod this car now that means no money saved up for an ft-86 later!

sorta in the same boat, iv had my 92 SC300 since June, and put down 3000 miles on it thus far, it has 88k original miles. I want to mod it sooooo bad! but im keeping myself in check and not modding it for at least a year and a half. So far its stock, no mods. Its hard though, but i think if i save the money I am going to use for modding for other bigger better things, i might be happier. AKA FT86.

1UZ is an awesome engine, iv had the privilege and opportunity to help build a few conservative 600+ hp engines. They respond to mods very well, much more so than the JZ/RB/LSx engines. However if your thinking of using FI applications in the future there have been less problems with the NON-VVTI 1UZ vs the VVTI variant.

I knew for sure it was lighter than the 7M, but wasn't certain if it was lighter than the JZ motors. Aluminum FTW.

As for the rods, it's my understanding that the early years of the 1UZ had beefy rods, but it was changed even before they got the power bump to 290hp. It may have only been the first year or two. I think the engines that were rated 250hp from the factory? (don't quote me, though...)

A VVT-i head/ecu swap onto the earlier bottom end sounds full of win. (with boost naturally...)

I've heard the racing rumours as well, something to do with a potential IRL design when Nissan was fielding Infiniti branded engines for the Indy cars.
