I am a little off topic here, but since I will be building an exhaust system from scratch for a 1UZFE in a Celica, I was hoping for some JBrady wisdom. Here are the facts. The engine will be a totally stock 1993 LS400 motor. If they fit, I was hoping to use a set of JBA shorty headers for a...

Hi NEXUZ I am also in CA, actually in Santa Clarita. I am in the process of getting the parts to put the 1UZ V8 into my 1983 Toyota Celica. Since you have it up and running in CA. I was hoping you could answer a few questions. Since you are a 73 you are not as strictly controlled as I will...

After thinking about the twin blower setup it actually makes more sense. At lower rpms the big Vortech is just like a pipe into the Roots blower so it will just get roots boost down low. Belt it for just 6 or 8 psi and it will still be stump pulling low end torque on a V8. Now as revs climb, the...

One odd idea I thought of was using two 4 cyl ECU's to run a 1UZ V8. I have not done alot of research yet, but this may be an idea for you. If you get two 2AZFE ECU's, they are set up to control a 2.4 litre 4 banger with VVTi on the intake cam. They would be running 90 crank degrees apart, but...

I crossed the diff ratios. I just re-read the page. 1990 - 1997 LS400 is 3.62 1998 - LS400 is 3.266 The VVTi motors make enough torque to push the tall gear. This makes it so my 3.727 is not that huge of a change. Good, it should run just a little higher revs than stock while cruising...

Due to the California emissions rules, I have to use a USA spec setup. I may even have to get all of the CA specific stuff as well. This pretty much rules out an import cut. As far as price goes, I won't bid over $1500 on this one. What makes it good is that I get the whole car and it runs. It...

It looks like I have found a donor LS-400. The car is a 1993 with 187,000 miles on it. It is a complete car that starts so I know it has all the hardware and wiring that I should need. This car was in a fairly minor crash, but since it crunched virtually every corner, the insurance company...

I talked with someone a while back about running a 4 banger VVTi motor with an Electromotive TEC II. The ECU didn't have the control needed to adjust the VVTi oil control valves to adjust the timing over the huge range that the factory ECU could. The idea they came up with was to modify the VVTi...

I am not a boat expert, but... In the boat application, you may want to re-prop it to make use of the higher rpm range of the motor. Cruise rpm should run at 5500 to make best use of the engines power band. Using a lower pitch prop is just like using a lower rear end gear in a car. It should...

When I was messing with cams in my 4 banger (soon to be replaced with a 1UZ ;-) I found I got a much better power curve with a narrower angle between the intake and exhaust lobes. It would be interesting to see what you end up with advancing the intake cam (1 tooth would be 7.5 cam degrees...

It has been a while since I was able to even think about this project, but I am back now. I will be visiting my car and hopefully putting some money down on an engine (wrecked car) to get the conversions started for real. From all the searching I have been doing I have decided to use the...

I think I am going to look for a whold car a bit longer. I need alot of parts out of the car and want to make sure it all runs before I start the conversion. Since I am going to be using the auto trans as well, I will also shag the shifter out of the console. I am budjeting this project at...

Thanks. He must have the wrong year. I thought the GS400 was more recent that 94 also. I don't think I want to tackle an OBD II swap from 2500 miles away. I will tell him to keep looking for an 89 - 94 LS-400. This is certainly a more powerful engine, but it is also double the wiring to...

I am still in the research phase of my swap, and I understand the LS400 has a front sump oil pan which should fit into my 83 RA65 Celica. But I have not been able to locate an early (89 - 94) LS400 donor car yet. But my friend has found a (he thinks 94) GS400 that was rear ended. I can get the...

My car is a left side driver (US car) and I plan to use a US (maybe cal spec) LS-400 setup. so I hope the left side exhaust manifold has room for my steering shaft. I know it will be tight, I had a heck of a time fabbing my 2.5 inch mandrel bend downpipe from the turbo. I am also hoping the...

I certainly wish I could run a programmable ECU, but such is life in California. I still don't have the answers back from the C.A.R.B. referee people, but I think my car will even have to report the proper codes and all out the ECU dataport. Some cars as old as 1990 are connected to the test...

$850 is a good price for the motor, especially if that comes with everything needed (ECU, harness, trans, cats) and who knows what else. I have not heard back from my Chicagop friend yet, but if what he says is true, I should be getting an entire LS-400 for $2000. After I yank out everything I...

I contacted one of my car hacking buddies back in Chicago and he is looking into a rear ended LS400 for me. He thinks he can find one within a month or two for under $2000. He goes to insurance auctions all the time to buy totalled out cars for parts. The sorta plan for now is getting a whole...

That is very cool to see. I thought the RA-60 and 65 were a bit further apart. MY 65 is the same front end and all, and my car is also red. That V8 looks like it belongs in there. The pictures have really got me excited about getting mine started. I am going to contact my friends back in Chicago...

50 psi of booost?? What doi they burn for fuel? All of the motors I have tuned were based on Chicago pump 93 Octane. The 91 octane of Topeka killed my previous motor, even with a richer mixture, reduced boost, and less timing advance. Fuel quality is certainly the limiting factor in cylinder...
