Hi guys

I've had a good search about this but still have some specific questions about what I can do for an engine conversion

The car is a 4runner with the auto and injected 4y. Its going in for a service tomorrow and I'm expecting the mechanic to say something along the lines of bad luck, burnt valve, farked head etc..... its been having problems

Good riddance to bad boat anchors I say... I'll actually be upset if it turns out to be minor
The auto allows me to use any motor that came with that auto in any toyota vehicle

so I can take my pick effectively as long as I can get the auto bellhousing to go with it
***I need something that will fit without a body lift.... no body lifts

I'd have to get that approved the hard way and that's a headache I don't need. What fits at std height of ifs vehicles?
***Turbo 4, na 6, turbo 6 I don't really mind (as long as insurance is aok) but what do you do about a/c etc

I'm guessing I can't retain mine

I'll have to get the a/c to suit whatever motor I buy
***Same question for power steering
Basically I need to know what fits and works with my gearbox..... will fit in my engine bay..... have adequate power (150hp plus min.).... and be easy enough to buy at a reasonable price and insure. What have others here done

I've searched the net high and low and learnt a lot but its all bit patchy
Opinions???
