Apart from updating to say Mr. MV6copcar is a legend and lifesaver

, thought I would at my 2p on the engines.
All the LS's (IE the fuel injected chevy V8's) are alloy block and probably as heavy if not lighter than the V6 already in there.
You can crate a new one over for reasonable cash, but your gearbox will be pricey, but there is more stuff out there for a chevy V8 than any other engine. 8 forged pistons cost the same a 4 for an evo or 200sx
A friend has one in his 200sx S14, runs 400bhp with the same torque with a stand alone ecu (cant remember the brand, omex probably) K&N and modded exhaust still with the cats, fair savage and makes the right noises, with massive room for tuning!
The 1JZ/2JZ is heavier, but there is not a lot in it, uses the R154 manual box which is the best money for strength box you could probably ever get (and actually you can get a chevy to toyota conversion bellhousing from the states if you really wanted) and is good on standard internals for 600+bhp. The engine and box would be cheaper, and getting it to similar+ power than the V8 would be too, but would be an (despite possibley the best jap lump ever) an older engine. You would also need to make intercooler room and the fact it is a turbo'd lump will lend more to heat and teething problems to start with.
But at the end of it its 6 of one and half a dozen of the other. A 400bhp LS would be a quick as a 440ish bhp 1JZ if only because of the instant grunt, but I have driven/drifted a couple of JZ'd 200's with 450bhp and when on boost its just savage!
V8's in drifty land are taking over, just useable, affordable, understressed grunt! Plus the LS is all part of the GM family, its got to be the onbly way... although...
