nah KAI, SPL are 1000ps... Plus I'll probably get a PPG gearset later on anyways...

yesh I'm one of those people who A. loves HKS things and B. the intake noise from a KAI.

You wont have a choice once your stock box sees that amount of power it's on borrowed time.

Wishlists and dreams aside; you need way more than 20k.

I think a reliable 400kw install can be had for $20k fairly easily, even as low as $15k if you're selling off your old parts. My only hesitation is whether the rb25 gearset is significantly weaker than the 5-speed in the r32 26.

Of course this assumes you are prepared to wait sometimes for bargains, only spend money where it's needed, and do 95% of the stuff yourself.

Buying parts from abandoned projects is a great way to save yourself some $$, for example I bought a complete head with my desired valve train setup for a little over a couple grand, whereas buying the components and having a shop set it all up would have run me easily more than $5k. Just an example.

Best thing is to sit down and price out everything you need down to the dollar.

Also think outside the box - for example running an rb26 head would get you a big side entry plenum and twin turbo configuration for a lot cheaper than simply throwing out cash for store-bought bolt-on stuff for the rb25 head. Sure you lose VCT but you gain ITB's. IMO it would be cheaper to modify OEM cast iron manifolds and run twin turbos capable of supporting 400kw than to just buy a 6boost manifold and a big single. Anyway something to think about at least.

Unless you are thinking of paying someone else to do it all, in which case I have no idea what it could cost.

T51, E85, you are talking about 500rwkw+ setup here.

If its 400rwkw then that's much cheaper, easier and perhaps only partly unrealistic.

i mean first off the car is RWD on the street, and let's be realistic here, that's a limiting factor there. 400rwkw is going to be unusable.

Even at 150km/h you are going to turn tyres on boost.Any RWD car will do that.

and let's be even more realistic, this isn't germany and we don't have autobarns. I can't even think of a road here in Victoria that would let you do 300km/h without throwing you off the road.

I think you need to sit back and look at this properly, rather than a friday day dream.

A 300-350rwkw RWD car will be faster than a 400+ on the street for one simple reson. Traction.

I suppose if the car was too powerful in a rear drive setup, it's always possible to turn down the boost for the street, or have a dual setting (one for dyno comps, one for driving).

If money is a hard limiting factor, my advice would be to build up the bottom end capable of supporting your dream power target, and get the best cylinder head you can afford. (I spent $11k on my bottom end, which included some pricey nitto rods, a nitto oil pump, CP pistons, and a bunch of stuff you won't need like sump adapter and bellhousing machining/redrilling).

That way, once the long motor is in, if you run out of cash for whatever reason you can at least bolt on your ancilliaries and have a driving car until you can save up more $$ for the rest of the gear, rather than having an unfinished project sitting in your shed frustrating you which ulimately ends up in a parts sellof.

Don't worry if you don't have a clear idea, I had no idea whatsoever when I started out, only what I had read here, and even that info didn't cover all the problems I had. You won't know what the problems are til you start and by then it will be too late to turn back, so best just to jump in.

    • Then today, I went to visit a man with an r33 hat Peter and Road and Race sorted the alignment. As it is being set up for general track/hillclimbs etc it has a heap of caster (7o), less camber than I am used to (1o front and 2o rear, as the caster looks after that in turns without the braking downsides), 3mm front toe out and 0 toe rear. Will see how that goes and track tyre wear to see if it does need more camber, but adjsustment is also limited with nismo arms and adjustable bushes at only 1 end. It does have a bent inner tie rod on the driver's side front but as it came up within spec I'll just leave that as is. So, that is getting close to my chapter of this story....could of tidy ups then a shakedown in early October before it finds a new home.
    • So, it went to Unigroup for a run in and tune on Friday, everything went (generally) well. In terms of fixes, the engine was good and there were no leaks. It needed plugs (I hadn't checked them because the coil pack cover was on a new engine and I couldn't imagine they weren't new.....but turns out the temporary plugs to just keep it sealed up were in there.....new plugs gapped to 0.8 and it was fine from there. Also, there was a little preload on the clutch slave which caused some slip. I haven't had the box off so I don't know what the clutch looks like; my guess it is brand new and the pedal had not been adjusted....backed that off a bit and it held fine. Last thing will have Dose crying....the idle especially when cold is a bit difficult between the cams, forward plenum, atmo blow off valve and an 80s air management system. It is fine when hot but a little uneven when cold, will see if I can sort or at least improve that one cold morning. Other than that, tuning went fine. It made 245 but was pulled back to 227 which 2 opportunities to improve in future. 1. The factory CAS is not great and was jumping around at high RPM, so Mark took 2 degrees out up top (that is why it stops making power and lost 20kw). Very safe this way and the extra power is available but will require a more modern ECU and better cam (or even better crank) sensor 2. The 2871 in factory housings is very big for a low mount, and the internal wastegate is too small, so it was creeping from mid range all the way to redline....the duty cycle on the boost controller is turned down a little for safety. That is much harder to fix, it would need a large external gate and that would require a whole bunch of other changes, so it will go as it is for now. It feels nice and healthy and safe, so should be good for about a billion laps like this.
    • what sort of caliper are they? If they are a slider and you gave everything a good clean, you might need to regrease the pins. My guess though is they will come good after some abuse as suggested above
