 Need planning help for 4runner swap
I've got a 98 toyota 4runner 4x4. I was originally planning on using an LS1 but as I've gotten more into the research I have been getting more and less confused.
I was planning on using a smaller or lower powers LS series motor because I am planning on backing it with a 4wd NV3500. They seem to be rated for about 300lb/ft of torque even though there are stories of them taking quite a bit more. It also weighs quite a bit less and using an NV4500 kind of offests the weight savings of an aluminium engine.
Anyways, questions.
What aluminium blocks are there for the LS and what are they out of?
4.8, 5.3, 5.7 and 6.0
What are the iron blocks(I'd deal with the extra 65lbs) out of?
5.3
What would you recomend me getting the engine out of? Make model and year. I was thinking an LS4 would be nice because of the compact accessories on the front.
Any other advise or links would be handy.
Thanks
