1uz

Hi. I have a 1UZ, A340f using the factory ECU. The transmission has suddenly stopped shifting when in drive. I have checked (at the ECU) BATT, B+, NSW, STA, IGSW and they all seem to have power when necessary. I measured there signal between NCO- and NCO+ and also between SP2- and SP2+. The...

Hey all, Working on my first Lexus engine but I was a little thrown by this one during my rebuild I am doing on my 1995 1uz non VVTI. I have multiple places including videos and a lextreme post, Rods and Main Bearings post that all say based on the block, crankshaft and cap that have numerical...

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...

Hey guys, I'm in the market for an LS400 and I have 2 on my radar so far. I found a 1993 with 93k miles and and 1998 with 81k. 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...

sooo i’ve put a 93 sc400 1uz in my 91 cressida, i got the harness done by a shop and they came by again today to make sure the wiring isn’t the issue, so, the car starts up strong revs to about 1500 and shuts off. it runs the same amount of time everytime, i’ve ran codes i only got some for o2...

Hey ya’ll new member here. In the process of a manual swap on my SC400 and looking to do a write up on it eventually. Using a Z32 trans and not using any kits trying to do all of this on a college students budget. Anyways since my trans is dropped I decided to change my Rear Main Seal...

Hey guys, here's the details below. This one has stumped many shops and I'm finally honing in. I would like to avoid building and installing a stand-alone harness for both the TPS and MAF circuits and feel that this testing proves the circuit in the ECU itself is shot. All parameters are reading...

I have a 87 Cressida and I plan to put a sc400 1uz in it and I’m trying to figure out what all I’ll need to use the w58 trans that’s in it. Any ideas?

Hello everyone, I'm creating this thread more of for myself but I encourage anyone who has any kind thoughts and knowledgeable information to post here too (hopefully we can stay on topic). :) As you can tell by the title, all this thread is just my personal blueprint layout for my plans on my...

I'm looking to get some more power out of my first gen LS400 and people were saying to start with an aftermarket ECU. Some say the Link G4 is good, not sure exactly what im looking for. Any recommendations?
