This is the plan .

Build an R31 with a VH41DE ( Nissan V8 4100cc )

Heres what i have .

I bought a VH41DE half cut for $ 1750 delivered

Bought the wagon for off ebay for $ 900 . It has a mint body . Replaced the diff ( $ 80 ) , replaced leaky water pump ( had a spare ) . Got it registered 3 weeks ago .

I plan to keep it looking as stock as possible , even down to the hubcaps .

Am only interested in going fast in a straight line , drags and on the salt flat .

Deliberately chose the 4100 cc engine to suit the class ( F = 3000 - 4300 cc ) i want to run at the salt lake speed trials .

OK . Here is a pic of the wagon i raced this year at Lake Gairdner speed trials . Was running a RB30DE . Best average speed over 1 mile was 141 .187 MPH ( 227.21 kmh ) . I saw 152 MPH ( tacho reading ) at the end of one run . Engine basically stock with 370 cc injectors , extractors and 2 x rb25 throttle bodies , apexi safc 2 , and thats it . Standard cams and head .... NON TURBO

Nice work on getting the VH41DE.

What sort of Gearbox did it come with? Auto or manual? and what sort of box will you be using?

do you plan on modding the engine or running it stock? How much will it set you back to cet the new engine in and running in the car?

Is your other R31 with the RB30DE for sale :(

only ever seen them with auto's behind them... AFAIK they didn't get sold with a manual option..

and every combo we've tried doesn't work, rb/vg/sr etc boxes all have a different bell housing setup, the VQ boxes might go but not sure..

however locally in perth someones developped an adaptor plate to slap a 25 box behind it, well any RB box really, but 25 for the strength, needs a custom flywheel, but its workable, PM me if you need more info on who to speak to

Mods will be limited to extractors ( home built ) , cams if i can get the stock cams ground , malpassi fuel pressure reg , Apexi safc 2 and a decent air intake .

I will be doing the installation myself and am going to tackle the wiring up too .

I will be using the auto box the engine come with , cheapest and easiest option for now . Fitting an rb25det box would be a good option , but but would cost more than my whole half cut by the time its fitted .

The red car is not for sale yet, as it will still be my daily driver until i finish the blue cars conversion . Hoewever will be selling the rb30de engine at a latter date , maybe towards the end of the year .

Its not a priority but it would be nice to have it all done for a total of less than $ 5000 ( including purchase of car and half cut ) . 150 Mph + for less than $ 5000 , i like .

Spent many hrs on saturday , disecting the harness . had pulled out all engine bay harness and in car harness . Massive amounts of wiring . Found a total of 6 computers . Only using 2 of the computers , engine management and auto trans . Believe i have all the wiring i need after chopping out one big box full of surplus wiring and electricals .

Good luck, the wiring is probably the hardest part of setting something like that up.

it is, took my mate a few solid nights and some weekend time to sift thru everything tracing wires to see where they went and what they hooked into, the amount of surplus in the looms is astounding..

AH tell me about it . Have spent many hours unravelling harness . Thought i had it right , then discovered i had chopped out 16 wires too many that go to the transmission ecu , a big BUGGA . Have had a lot of help from NICO forum in sorting that prob out .

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
