If your thinking of keeping the RB320, and buying another fun car, then I would not buy one to do the project yourself as it will cost dearly to do it from scratch. There is plenty good cars out there that will make you smile from ear to ear at £10k all in.

Hi there newbie to this site. Owning a p1 myself for over 4 yrs now had 3 engine rebuilds over the years (apparent subaru specialist) and now waiting on my 4th 🙈 spent around £10000/£12000 with a previous company well it's actually only 1 bloke by himself but anyway I'm back to square 1 now so not a good way to spend that type of money and basically start again.
I have now taken her to Api for a 2.5 build around 460/480bhp with more torque previous had 2.0 around 350bhp which will be your limit with a 5speed gearbox and clearly over the limit my supposed forged engine could handle.
Are you going 6speed setup too?

To be honest there's people selling forged 2.5's in saloons for 2/3k , got offered a full car the last week for 3k, the price of the engine alone comes to 3,000 with all the upgrades, obviously with provided reciepts, then I'd have the shell , 5spd box, standard p1 engine to strip n scrape money back , but yeah I would go 6 speed just because I'm driving the rb now and couldn't imagine driving this engine with 5spd, the ratios must be shorter or something
