    Spec r will likely be worth more in the future. The sr can be made to hit 500bhp but it’s not cheap and you’ll need to fit a stronger gearbox. A 500bhp sr would also likely be slower than a jz version with the same bhp.

    If one of your first worries is which one will hold it's value more, then I would suggest abandoning the idea completely.

    Both will ultimately be a converted Spec S. And both will cost you way, way more to make from a base car than you will ever get back.

    A 2JZ conversion in Europe these days is the best part of £10k, assuming you can do all your labour and wiring yourself and you buy a dog sh1te turbo set up.

    A 500 hp SR would be easier to put together, but also wouldn't be cheap because of the supporting work.

    will the 2jz handle worst as its heavier than the sr would you know ?

    You'll never drive the two cars back to back, so you'll have nothing to compare to. There don't seem to be many complaints about engine mass re: 2JZ in S body on the net. Even though I bet it's a good 75kg heavier.

    I think OP meant buy a SpecR SR20 S15 or buy a SpecS and convert to 2JZ?

    If that's the case, i'd say a Spec R would be better investment.

    Why are you chasing 500bhp spcifically? What's the use going to be for?
