I have not had it on a scale yet with the V8, but I will as soon as I get a chance. Mine is also a coupe RA65C, I picked it for the lighter weight as well. It has full interior and a sopund system as well as chassis braces and the coil over suspension. Last time I raced it with the turbo motor...

Al, It sure was a ton of work in a very short amount of time. I took about 2 weeks between work and familly time to plan out every thing I had to do. I made a check list and diagrams of everything I could think of. If it was not for that organization, it would have been impossible to pull off...

A friend is posting more pics on his web site, I will put the URL up here when I get it. I have a few close detail shots of the modified driver's side exhaust manifold. Since mins is a US car, the steering shaft problem is on the left side. Left hand drive people have the exact same problem on...

BIG NEWS TO REPORT IT'S ALIVE!!!!!! Thats right, after a very long delay, I finally took a week off work, flew to Chicago, and spent 4 days working almost straight. Yesterday was about 22 hours working on the car, but my trip is over and I am on my way back to L.A. I will post a pic or two...

Not much new to report other than I am setting up a trip back to Chicago to get the Celica/Lexus up and running. If all goes well, I will be at a much nicer shop with 2 hard working buddies on Aug. 28,28, and 30th. With a real bay to work in, and good help, I think it will be running after that...

I have not seen how the new GM DOD system works, the old V8-6-4 system moved the rocker arms sideways off of the valves. Mechanical nightmare. To me, the smallest pumping losses would probably result from keeping the valves partially open so the air can flow without compressing or creating a...

25 years ago would be 1981. Wow, some of the cars on the road back then were pure junk. The stupid things detroit did to try and pass the tightening emissions requirements made working on some of those cars a nightmate. My fathers 79 Lincoln Town car had a 5.0 V8 with a 4 barrel carb rated at...

TechTom makes a board with a programmable ROM they install inside the ECU that can alter rev limints and shift rpm points on the 1UZ. It is far from cheap, but I think it is the way to go. They list it for the SC400, but not specifically for the LS-400. I would assume the code is similar, but...

I have tuned several high performance engines with MAP sensor based EFI. It ends up working very well and can make huge power quite well. The biggest problems I ran into was at light loads, especially on a Honda with big cams. Idle was near impossible to tune nice with just the MAP sensor for a...

I am also watching here to see what any one else comes up with. My 83 Celica 1UZ should be running and coming out to Cali in a couple months now. 250 crank hp in a 2700 pound car may seem like fun, but we always want more. My first thoughts were to run a little more aggressive cams and have the...

Assuming you have an A341E (or a340E for that matter) I might be able to help. I have been running around trying to figure out the speed sensors myself, and what I have come up with is a couple possibilities. Depending on the year of the trans it will have 1 or 2 speed sensors in the tail...

I have the complete 93 LS400 service manuals, and the only error code listed for the sub O2 sensors is if they don't go to a rich reading after several seconds of > 70% throttle driving. This would be an open loop condition which should be richer than 14.7. The cats will absorb oxygen when...

Peewee, With a little careful fitting, my friend got the Lexus rubber drive to fit, check out the pics on my Progress thread. The Lexus drive shaft actually fit inside of the original Celica shaft. It is a nice snug fit and runs true, so he welded it up and it will make the car drive until I can...

I have to agree that there would be no fit problem with the 1UZ into a Nova. We have the 1UZ stuffed under the ood of my 83 Celica with some room to spare. You will need to choose the correct oil pan setup depending on where the cross member lies, but other than that, it is a fairly small engine...

I will probably be making up something better when I have the car out here in Cali. Tom (my friend doing the install in Chicago) is good at "making it work" but his details are a bit rough. The mounts holding the motor in place in the pics are nothing but some heavy wall water pipe with a big...

TECHTOM has come up with a daughter board that they install inside the ECU in place of the CPU chip with a reprogrammable memory (I would guess a flash type) but it is quite pricey. They list it for the SC400 and have not tested it in an LS400 yet but say it should work fine. The only real...

How much of the trans needs to be swapped out to change to a slip yoke? When I asked about that a coupole months ago, it sounded like I would need to tear it down quite a bit to change the output shaft of the trans as well as the rear housing. And the slip yoke rear housing would not have the...

Sorry this post gets long, but I am thinking to myself while I type as it helps me catch errors in my math. Thanks for the reply. I would also assume the LS and SC cars from similar years would be the same. So SP2 is 4 pulse per rev of drive shaft. If SP2 is in fact a 3:1 ratio off of the...

I finally found time to resize and post the pics. Too bad these were all taken before the progress I made in Chicago 2 weeks ago. I will write up more later. I also made a good haul at the jumkyard and have most of the odd parts I need to get this thing closer to running. I found a 1984...

Still no response, Hmm. I picked up a few pats from the junkyard to try and get going on this, but I had no luck finding ANY late model Lexus for testing. I did pickup a 1983 Celica dash to experiment with and after I took it apart, I finally found the numbers printed on the face. 1026...
