LS Upgrade - Help

[rs_man]

Hi Everyone, I am looking at the options of replacing my old SBC engine with a later LS. I have spotted this engine for sale :
http://www.pistonheads.com/sales/1438759.htm does anyone know anything about it and what would it be worth. What parts would I need to change i.e. headers, engine mounts? gearbox adaptor? All advice appreciated. Thanks Tony

Is it an LS alu block? Looks more like a cast block IMO

It states LQ9 Block that's a Truck block and yes its Cast Iron. There a cheap and good starting point for a High HP motor.

It has plenty of trick bits and lots has been spent so could be a great starting point for a very wild N/A engine.
Kinsler might be a bit more challenging to tune for the street though.

Alternatively, a brand new factory LS3 480 at similar cost, with some good headers, intake care and mild tweek will give almost the same HP figures, plus 25mpg when tootling along!
Depends which way you want to throw yer money!

You would need to budget similar installation costs for either engine option. Id think 5.5-6.5k should get the adapter, clutch, mountings, full exhaust, air,oil and fuel system sorted.

Trickier than it sounds, Kyle's been doing mine for a long time. In fact I'd speak to him about it directly.

There's a Youtube video of that particular motor running in a GTR on a dyno (somewhere), speak to Mark@RapidGB about it because they built it.

Thanks for the info guys. Can you explain why it is trickier than you think. What are the major hurdles. Anyone know the cost of the gearbox/flywheel adaptor?
