Hey guys im doing my first engine swap on my mk3 and was wondering if the 3uz sump from the ls 430 is better or equal or worse to an sc 400 rear sump for subframe clearance. Ive read on older forums to go rear sump for mk3/mkiv swaps but Ive also seen a minority of people on facebook groups to...

I have a 95 sc400 that I have rebuilt; broken valve engine will crank and I am sure my grounds are all good. The spark plugs have no spark on either bank and I do not hear the fuel pump engage at all. Starter will crank the engine but it will not fire. The only wiring I have done to the vehicle...

Hi all, I recently bought a non running ucf20 LS400 1996 hoping to get it going easily. I later discovered the previous owner had replaced the ecu and had no luck starting it since and the old ecu is gone. I have tested cam and crank sensors, spark is good, compression is good and it will fire...

I have a 1uz swapped cressida. The issue i have is it will not crank like the starter isnt getting enough juice. It had the original starter, so i replaced it ( autozone duralast) still had the issues. I thought it was a parasitic draw but it is not pulling any excessive amps when off. I also...

Hi All, I am very lost atm... These issues started when I was at the gas station after being on E for some time on the highway. When I pulled into the lane I noticed the battery light and red oil pan light come on and after filling up it did not start up (Very embarrassing situation overall)...

So I recently picked up a 93 SC400 with one of the early 1uz's, I've had lots of experience with I6 toyota motors but never touched the UZ. It has 100K miles and on the way home while driving it the timing belt slipped off, when inspecting it the belt looked thrashed and cracked. My plan is to...

Hey! I'm very new to the 1uz. How much would it cost to get a 1uz to 400hp and it being streetable with a 6 speed. I've been searching quite the lot and can't get a set answer. Also if extensive mods are done is it possible to track the ls400? Ik everyone would say swap the 1uz into another car...

Im going to go look at them this week to see what I like more, and I've decided that if I get the 93 I'll boost it. This car is going to be my daily and reliability is a...

Hey Guys, I just inherited a 1993 SC400 w/ 1UZ (55k miles on odo...but...she has been sitting for almost a decade under a carport). I have loved this body style (almost as much as a MkIV) since they premiered while I was in school as a kid. I know it has about 290hp based on specs; but I want to...

After many years of planning a 1UZ project, I've finally gotten around to doing it. I just needed to find the right car. I considered a number of smaller RWD Toyota vehicles to take the 1UZ and stay true to the brand... I even considered the Lexcen (google it)... but I've always been a fan of...

Hey guys I'm hope someone can help me out cause I can't find any info anywhere. My sc400 1uz auto needed a new auto fitted, so I brought one out of a soarer 1uz thinking they would be the same, but there is one plug on the auto at the left rear (think it's the shift solenoid) that is different...
