Thermactor, This is from a 97 Celsior and has the U2 bellhousing. Are you sure this is what you want? Air freight from here is about $500.00, I think, but I can check if you want it.

Hillbilly, I really appreciate the help. I think I will end up with a much better engine going the route I have now chosen. I will be sure to post when it all gets sorted out and running. Only a small delay.

Headbolt question Hillbilly got me thinking when he told about the conecting rods being weaker on some of the pre-98 1UZ engines. I had believed that only after 98 the rods were different (weaker). I have the rods that Hillbilly experienced broken and bent in his engine. I am glad I looked. It...

I used the ECU to identify the engine. It is "175000-8110-12V". Am I correct in thinking it is a 96-97 Celsior. Front sump.

Hillbilly, Thank you for the heads up on the rods. I will have to figure out what I am going to do now. Anybody have an opinion about using a 96-97 1UZ engine and boosting to .8 bar (11.76 psi) and reducing the compression to 9.1 with a thicker head gasket?

Hillbilly, I have a 96-97 Celsior. Yes, the reason I am considering a thicker head gasket is to install twin Garrett 25R turbos. The boost will be around 1 Bar.

Lex, Looks like my project is going to include engine decompression with a thicker head gasket. The gasket will be a total thickness of 0.0985 inches (2.5019 mm) to reduce the compression to 8.5 from 10.4. May I please also order some ARP head studs? I need it to be sent UPS.

thalj, hello in Dubai. I recently started a thread asking for comments concerning supercharging or twin turbocharging for the 1UZ that I have installed in a new Toyota truck. For my driving and personal preference I decided to go with Twin Turbos. I have a stock engine, '97 Celsior, and it...

Lex, Thank you for the information to the link. Andrew k.

Justen, My goal is low boost and high low end torque. This is my daily commute vehicle. Driving to and from work should be fun when this gets done. i will post my dyno numbers when it is completed.

The gearing I have is 3.583 LSD with 4.313, 2.33, 1.436, 1.0 and .838. I am going to add twin turbos (Garrett) with an air to air intercooler. Shooting for June 2nd completion.

I still have the ECU.

Thanks Peewee, you saved me a trip into town to look. Andrew k.

Aaron, I will have to go down to where I have the transmission this week end and check. I did not even pay any attention to the gear box. It was part and parcel with the engine when I got it. It is a U2 bellhousing from a 1996/7 Celsior if that make a difference. Let me check and get back with...

twin turbos or supercharger Stevechumo, Thanks. Great information. Because of where I am in the world I have very high import duties to pay for anything brought in. Anywhere from 30% to 300%. I really like the idea of twin T-25's. Fabrication is no problem. I have an industrial machine shop at...

twin turbos or supercharger Thanks for the comments. My truck is my daily driver and being fun to drive would be a good thing. All the bits and pieces for twin turbos are available here in country for me already. To go to a SC would mean I have to import (and pay 30% or more in fees). I have...

twin turbos or supercharger e-solver, Thanks for the post. That is good news to hear. I used a Dellow bellhousing and a one ton clutch with a brand new stock R151. Any personal preference for twin turbos or a supercharger on a stock 1996 1UZ in a Toyota truck?

Twin turbos or supercharger Jibby Thanks. I wanted to go with a supercharger but some others have suggested twin turbos. In either case I don't think the tranny will hold up to more than about 300 hp or so. Anybody know the rating on this box?

I would like to get the comments from anyone interested. I have a 1UZ from a 1996-1997 Celsior swapped into a 2006 Toyota 2wd truck. The stock engine was 3.0 turbo diesel rated by Toyota at 163 hp, more like 95 at the wheels. The rear end is a 3.48 LSD stock and the transmission currently is a 5...

idling issues Nemesis, Sorry I could not help. My offer is extended to any member that needs my ECU for personal use. It is a 175000-8110 with pins 34/22/16/28
