Engine decision?
Discussion
I would have thought the LS7 is the ultimate one to go for but I guess quite pricey.

ive a sbc but nowadays it cheaper but old
ls are nice but again old school, 2 valves per cylinder
audi rs4 is a lovely motor and with turbos and boost you will get some serious hp with reduced weight
v10 sounds great but sounds like a lambo, effective but not extreme, and expensive and hard to tune.
id looks at rs4 or ls3 with 2 turbos. or throw a curved ball and say 3 or 4 rotor rx8 engine. :0)

I think it is best to be realistic about your budget and your skills.
An LS engine is the easy route as all parts are available and the expertise is not too costly if you can't do things yourself.
If you go another route you tend to be entering the unknown to a degree. It can, and has, been done but you do need more knowhow or have to pay for the expertise.
The LS3 is a nice entry level and can be upgraded in the future as funds allow.

About 13-15k ish from AS
HOW MUCH!!!!!!!Subslee said:
How much that setting you back?
Try here http://shop.partsworldperformance.com/
There will be bit you need to source from elsewhere...

I've done some research and sourcing elsewhere than AS like from PWP and getting the missing parts more locally (UK) is cheaper.
Regarding engines, an LS3 is a nice, cheap, powerful and probably troublefree solution. LS7 is more expensive and has fancy Ti parts, but have you thought about the LSA? It has been installed in Ultimas with no major problems, including tweaking the TB from the front.

17k us dollars with transport etc. I had assumed from most builders that the AS route is the best option to go. Yes I very much want something that works out of the crate as this will make my build much easier. Perhaps if I was wise enough to know the exact changes made at AS in order to fit the GTR I might consider looking elsewhere but the advice I have generally been given has been the AS route

Did you call AB? They'll do you a fully plug & play LS package of everything you need (plus a few shiny extras!) and save you some money over AS.UltimaCH said:

Now that's and interesting option! Any pics of them installed in the Ultima? I wonder if the LS9 intake could also be adapted to work? Or maybe, as a cheaper solution something like the Magnuson Heartbeat supercharger? Regarding engines, an LS3 is a nice, cheap, powerful and probably troublefree solution.

Hey 356speedster who is this AB you refer to? I've had my build on hold for the last 2 years but after a busy month on it, I'm now at the point of needing a motor for my CanAm. I've got the engine bay kitted out ready for an LS3 but I don't have any of the ancillary items for the engine and I had originally thought of PWP and then sourcing other parts from around the UK, but I'd like to check out any other (affordable) options as well if there are any.

I've ordered my chassis but I'm still undecided which engine to go for, I'm thinking small block, LS3, Audi 4.2 v8 or a Audi 5.2 v10. I'm also open to other ideas. Could you please give me a hand or give me some pro/cons please.
This one has been discussed a lot over the years - there is a LOT of information on previous threads. The bottom line (IMHO) is this :-1) Buy a turnkey engine package from AS and a factory supplied exhaust and it is guaranteed to fit and pass IVA on noise and emissions. This is the route to go if you have the budget and you want minimal fuss. (This is what I did, and it worked perfectly)
2) Buy a crate LS motor from a UK supplier and source all the extras yourself and eventually you will get it running, and it might pass IVA first time, but what you save in money you might lose in time and effort, and if you don't know exactly what you are doing, you may end up spending just as much money. This is the route if you are more experienced, I think.
3) Buy an SBC motor, which is a cheap-and-cheerful engine but will do a good job, albeit the technology is quite old now. This is the route to take if you are counting the pennies.
4) Go with an Audi or BMW motor, to be a bit "different". There may be some work to do with the wiring loom and ECU choice to get it running, as the Ultima will not have a lot of the connections that the original car has. This route is for experts only, I think.
Best of luck with your build, whatever you decide...
