1UZ differences LS400 vs GS400

[GSMnow]

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 whole car for about $2200 USD but I think it is mid or rear sump. Does anyone know for sure? Also is a 94 GS going to have an OBD I or OBD II ECU? Is it still 2 distributors or did it go to coil packs in 94?? He is still looking for an LS400 for me, but still has not come accross one in my price range.

I do want the whole car since I must do a complete transfer of all engine systems to make the drive train completely emissions corect for California. If I go with an OBD II it must report everything correct at the data link. This would even include the emissions canister and fuel tank leak checking.

Thanks for any info

I didn't think the gs400 came out until 1998. 1998+ gs400s have coil on plug and vvti

Only GS300 came out that on those years. If its a GS400 post 98. The oil sump should be interchangable.

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 make it all work.

I did see a LS400 engine on ebay that had 147,000 miles and it was a CA spec engine. It didnt have all the features on it.

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 about $4000 USD to buy the car and get a few parts made and hopefully cover some of the labor I will have to have someone else due before I fly back to finish it up. My friend back in Chicago has done quite a few odd ball engine swaps and can probably make it all run by himself, but that means I will be paying him for all the labor. He will also be storing the cars for me, the donor LS400 and my Celica.

Now I will probably end up with a Federal non CA engine in Chicago. But I don't think this will be an issue since the car will come to California already converted. So once again I will have to make a call to a CARB Referee center. I am going to pass it off as being done a few years ago. I have owned the car in Chicago since 1991 and I did run it turboed since 93. I will just say I was not able to ghet the car transported since I moved here, and that will be the truth.
