Need a Spot
I have a few '91 Monteros with one I need to put an engine into. Question: I need some serious horsepower, Is it possible or practical to put a 3000 GTG-----6G72TT [ twin turbo ] in this?

If not I will get another van engine but how can I get some real power to pull a trailer?

Thank You In Advance

Don.

There's no replacement for displacement so I'd swap in the Chevy 4.3 l V6 and tranny from a small Blazer. I have a 4.3 in my full size GMC Pickup; it will tow 5000 pounds no problem.

A 6G75 3.8 will bolt up to your bellhousing. You will need all the electronics, too.

Thank's whitelespaul, I'll look into that. Do you know of any links for for [done it before]?, to save reinventing the wheel. I've done my share of crazy swaps but now I'm getting long in the tooth and short of spare time.

Just got my 4th '91 Montero, a rust free southern rig with a lunched 3.0. It's a 4x4 auto to be my personal daily driver and trailer puller plus snow blade.

If you have done this or have tips on this swap I would be glad to reimburse you a reasonable amount for your time and
advice.. Thank You. Don

LandRaider has a chevy V6 swap. Fast Eddy's suggestion has some merit and may be easier than a full drivetrain swap.

Thanks wheeler and traileader for the leads.

Another question or two together.

I'm a new poster and most of the time I cant find the archive I need. I read the rules, any tips?

Main problem is the other, better of 2 drivers won't shift to overdrive/lockup and the local ?generic import ?specialist doesen't have a clue. Works fine otherwise.

I would appreciate a few hot diagnosis tips and also how to find this thread in archives. I'm sure it's there.

Thanks, torchman

Too bad an I-6 won't fit. Good torque, naturally balanced and very smooth running, and very durable. Good power can be pulled from an I-6 with a little tuning. Some can still be quite fuel efficient too.
