HR31COUPE

Was a load of fun out there today, thanks for the opportunity to come out and get some decent track time. Definitely know the weak points of the car now and what needs upgrading.

mods: RB25DETneo, 6boost high mount, GT3540, Turbo smart 50mm wastegate & screamer Splitfire coilpacks, HKS fuel rail & 680cc injectors, front entry intake plenum, Power FC fuel: BP Ultimate + Octane booster as a safety net power: 330rwkw @ 19psi, mid to high 200's @ 14psi useage:occasional street driving, light track work lifespan: been at least 3 years but would have been lucky to cover 2000km in that time failure: none but the tyres don't like it, lol comments: motor had 34,000kms when I got it 6 or so years ago, ran at 200rwkw on stock turbo until upgrade.

I too had grip issues, both under brakes/cornering and coming on boost. And that was with 265 Toyos but admittedly being 18's really doesn't help. Definitely going to get some 17's for track wheels and fit some semis.

For the guys that have times, were you doing your own lap timing or did they have it setup on the track for the day?

I can confirm this, I've got the 0.82 rear housing and it takes quite a while to hit full boost but when it does hold on. Good for top end but not response.

Mine certainly did, went from an Internally gated GT3540 on standard manifold to 50mm externally gated 6boost setup and the sound difference is amazing. Screams rather like some of the old group A cars do.

Sitting on 326rwkw @18psi currently, motor seems to be handling it fine but I don't absolutely thrash it either, no skids etc.

Cheers for that, I found out he had replied but my email was not letting it through to me. All good now though

Has kyle still got internet access? I was in cantact with him before xmas sorting out what size gate etc. I need for mine but now that I'm ready to order I can't get a reply out of him. I noticed he hasn't been on here since 28th dec. If anyone could get me in contact with him it would be greatly appreciated.

I got a gasket kit for one of those wastegates from Greenline motorsports part no 1409-RA022 Ended up being $41 delivered and took a couple of weeks.

I've got RB25DETneo Front Facing Plenum GT3540 on standard manifold HKS Fuel Rail and 680cc injectors Bosch Motorsports pump (044 or 040 can't remember which is the intank one) Splitfire Coils FMIC 3" Titanium Exhaust Power FC Got boost control issues at the moment due to internal gate, will be upgrading to external gate and new manifold. Currently boost starts at 12psi and ramps up to and holds 19psi, it was up to 337rwkw at one stage but the boost kept on climbing way past 20psi.

Cheers for all the information and suggestions so far, It is certainly a hell of a lot to think about and a hell of a lot of work. And please don't take offence at the 13yr old remark, I just understand that car forums get alot of "Dreamers" making threads about outrageous things that they never intend to ever carry out. As for the Attesa, I'm not too sure if I want to go the trouble setting that up, I'm wondering if there is a reasonably easy way to make it constand 4wd. I intend this to be a rather long term project due to the costs and research involved but I thought it would make an extremely unique and fun car. Might see if I can find a reasonably priced shell to start playing with so that I don't have to pull my current coupe apart until it's time to drop the motor in.

Firstly I'd like to state I'm not a 13yr old kid that has just been dreaming all day about this, It's something I have been seriously thinking about and trying to think of ways to go about it so I would appreciate serious replies. My goal is to try and make my HR31 coupe into 4wd as I intend to use it for track work. I have spent quite a while researching things but as I still have things that I require answers on. When people put RB26 motors into the R31 they modify the sump, obviously to remove the 4wd component but it is also for clearance issues with the cross member is it not? Now I know of the R32 GTS-4, and being the closest relative to the HR31 I would assume some things would be similar between the 2. Are front crossmembers from these vehicles able to be modified to fit into a HR31? Also from my research I've found that the Stagea was available in a RB25DET Neo 4wd option. Is this factual or not? The reason I want to know this is in theory I should be able to put the 4wd sump from one of these onto my RB25DET neo motor but using the R32GTS-4 crossmember to get the required clearance. This car is a long term project so $$$ over a long period of time doesn't bother me too much. I just haven't had the opportunity to see the differences between sumps, cross members etc. only what I have read so info from someone with experience in these matters would be greatly appreciated.
