Define your terms.  Easy, reliable and cheap mean very different things to different people.  "Reasonably quick" is also a very rubbery term.

It's very simple though without changing the turbo.  You can perhaps get up to ~200rwkW (depending on the dyno!) on the stocker, but you won't do it well without an intercooler and you won't do it at all on stock management.  You need to have a way to dial out the horrible R&R that the R33 ECU will cripple you with if you try.

30-40HP is in the realms of possibility without changing anything - just adding boost.  But stock boost is 7 psi and the limit is not much more than 10 before the ECU starts to rape you from behind.

It's not exactly same same with an R33 RB25, but my Neo is stock.  I have a bigger cooler, good dump pipe and ~12 psi.  And Nistune.  Without the tuneability I would not be able to run that much boost.  It started to get evil at 10.  On a sensible DD dyno mine did ~190rwkW recently, on 98.  There's not a lot more available without risking breaking the turbo.  Anything more serious requires at least a turbo, and an AFM or a complete new ECU to get rid of the AFM, and injectors.

R33s suck for ECU.  You have to get an ECU from another model (Z32 or R32 typically) and put a Nistune board in that, because the R33 ECU is a stupid orphan that even Nissan don't love.  Work on it being >$1000 to get an ECU into it and turned.  Turning the boost up costs very little. You just need a cheap boost controller.  A decent (electronic) boost controller will cost you a few hundred.

      Yeah kids certainly add a whole another dimension to your life.  Life ceases to be about you and more about them for a while!  And I wouldn't have it any other way.  I love watching them play sport and make new friends along the way. Wow, sounds like your mate is a good guy to know!!!  He's got some serious toys in the toy box!  Yes it would be lovely to be able to do stuff to your car without getting all tied up in boring shit like how to pay for it!!  I would describe my spending style as "aggressively spontaneous and logical but regrettable purchasing"....  That will hopefully make no sense at all which would be appropriate given that is how I buy stuff.  I'll decide at the drop of a hat that I'm buying something expensive, research the living shit out of it for 2 days straight then go out and buy it.  Then I'll have instant buyers remorse for 2 days which generally passes by the time it turns up on the front step!  If I'm feeling ballsy sometimes I'll tell my wife.  Other times it just makes its way silently passed the house and out the back to the shed, never to be spoken of again...

      My extinguisher mounted like this unscrewed a little (Maybe from the chair sliding forward) and dumped a bit of white on my mats. I'll need to get a more narrow one for future.

      I totally couldn't do the whole kids taking up my life thing! 😮 I find it bad enough doing 45 hours in 4 days, and then fitting normal adulting life into the other 3 with no kids! As for my mates race cars, they're AMG C63 setup for production racing. The original is what has just been stripped and a brand new shell built. The original is then going away to have some panels straightened, then it will be put back together again. Then there's a third that will shortly head off to have a roll cage put in, then build it up too. And potentially a fourth to be built too... Oh, and he has two Renault Clio D class production cars, ha ha. And when he's not racing them in the Australians and QLD production championships, he's been racing one of Chaz Mostert's Lamborghini's in GT4. They just won GT4 at the 12 hour in the Lambo. We're pushing to finish the new AMG as it has its first round (and potentially its first shakedown/outing) in under w weeks for Round one of QPC, and that round is really the shakedown to make sure it's all good for the Bathurst 6 hour, which I'll be at too. Ha ha ha Working on my project is different to his, I slowly tinker and work ways to make things happen on a shoe string budget. Hes in a good position that he has a massive workshop full of parts and tools, ha ha. He also looks after me. When his air compressor died, he just needed it working, so bought himself a new one and gave the old to me. Sand blaster unit too, and a 20t pressing. And pretty much all the shelving in my shed too as he upgraded all of his (the stuff he gave me is the expensive black Bunnings heavy duty stuff)!   I enjoy working on his stuff. No decision paralysis, and anything that's needed parts wise is just there. Plus, then I get to be hands on at the track in real racing, not just club day stuff.

      I know which one I'd prefer to have in my garage, and which one I'd actually drive as intended
