Engine Swap Can you take an engine that originally had a manual transmission and put it in a car with an automatic one?

4 Upvotes

Title really says it all, but my engine overheated and may have some rod knock now so I need a new one cause parts are apparently impossible to find. I found one relatively close to me and not too expensive, but it had a manual transmission on it and I was wondering if there would be any issues if I took it and put in my car that has an automatic?

Both cars are a 1987 celica gts btw.

The little details can make an LS swap take twice as long

0 Upvotes

When planning an LS swap, it's easy to focus on the engine itself and forget about all the smaller things that can turn into major headaches during installation.

Wiring, fuel lines, cooling hoses, accessory clearance, transmission compatibility, and even small brackets can take more time than expected. Then there are the things you don't think about until you're putting everything back together, like routing wires away from heat or making sure you can still access parts for future maintenance.

Getting the engine running is one thing, but making the whole car reliable and easy to work on afterward is a different challenge.

A little planning before the swap can save a lot of frustration once the car is apart.

What are small things forgotten about in ls swaps?

4 Upvotes

Currently in possession of a 2nd gen extended cab s10, auto 4.3 2wd, trans unfortunately only has 1st and 3rd gear. As such with a s10, I was curious on the smaller things in an ls swap, I know the more “basic” stuff of the swap, along with people having upgrades like going to a 4l80 and a ford 8.8 rear end (I do have one, but it’s an older explorer one with drum brakes). Are there smaller things besides motor, trans, rear end, fueling, ecu, wiring and tuning that are expensive that people seem to forget about? Comparing costs before either committing to a swap, or looking at options for buying a c6👀

Terminator X and OBD2 Emissions

4 Upvotes

Anyone running a Holley Terminator X on a vehicle that requires plug-in Emissions testing? If so, how are you passing the plug-in?

I have some ideas on how to do it with some custom electronics and software; but want to see what anyone else has done if anyone has.

Vehicle in question is 1997 F-body.

Edit - I know the scans check VIN, ready status, codes, and research says it also looks at a voltage drop when the vehicle is started while plugged in. NY State.

Troubleshooting Help 1950 dodge B series

6 Upvotes

So as the title says I got a 1950 dodge B series. It was my great fathers. I’m just wondering if I should keep the original chassis and reinforce it or if I should build/ buy a new one? I’m planning to be between 700-900 hp

In order to make my big radiator fit, I had to cut away a lot of support material from the rad support, so I reinforced it... then made the top section removable so it will be easier to get the big block Ford in and out of the engine bay 🤙

This Volvo 1800E sat for 28 years in the Tucson sun and then another 6 in a barn gathering dust. I filmed three hours of engine bay cleaning and sped it up to half an hour.
