Ditching the 3fe for modern performance and economy.

We have been doing engine swaps in Landcruisers since 1985, of course back then more power was the only concern, these days we all want our cake and eat it too. Thanks to GM's Atlas engine program which began in 2002 we can have the best of both worlds, great power curves and modern economy. This particular FJ Swap is our proof of concept test vehicle. While we have completed a few Atlas swaps, this build used for before and after performance data and verification of our transmission to transfer case adapter. 

Built in 1991 this FJ80 has 235,000+ miles on the clock (12,000 + on the Atlas) as usual the 3fe was still running strong and in decent shape. However our client was looking for some more towing power and economy. A perfect candidate for a 5 cylinder swap.

The Atlas installed. The fit is fantastic, access for service and maintenance has been improved over the factory motor. Clearance on all moving front suspension parts was verified by removing the front springs and dropping the truck onto the snubbers then lifting one side to articulate the suspension as far as possible.

Here we are building the custom fan shroud. We prefer to run motor fans due the high ambient temps here in the valley during the summer months.
