    Roman's 4GR V6 Carina discussion thread

    in Project Discussion

    Posted

    Keep going, I'm dreaming of 4gr altezza track hacks now

    What were valves like in the 1nz, obviously a small bore there too, was there any concern there? Yet again comparing this to rb20 (sorry) this is still a big bore, and 20s will happily rev high (maybe not make more power) so I'm guessing the engine characteristics of small light piston and rod ratio/short stroke count for more in pure rpm stakes, and the valves do enough seeing its smaller air volumes per stroke. 

    Hanging out tonsee how this goes

    Looks way smaller with covers off!

     

    Edit: added pic of one of my rb20det heads, looks like 4gr valve setout was rb inspired puhuhu

    also you'll be pleased to know i went down a rabbit hole on engines last night, spotted a contender for someone to tap potential, for a nondescript v8 the 1urfse (lexus ls460) looks like it has potential to apply similar 1nz/4gr logic too assuming those things can translate, geometry is a bit more 2GR so not as rev happy with heavier pistons at 94mm, but 11.8:1 CR, D4S, RR of 1.77

    For Questions Regarding WOFs/CERTs/NUMBER PLATEs

    You get a log book for the car and it has all the details of cage spec from Motorsport nz. You need it no matter if car regd or not. Getting a cage and proper safety shit is pricey these days and if if it’s not got a reg you need to trailer it to the event so that’s a cost as well. You can still do abit with just a regd car and have a ball doing it but you need to realise there’s no cheap Motorsport. It always costs 

    Cheers, yeah not expecting cheap but need to be realistic with budgets, the specific reason for asking is it seems you can pick up dereg silvias/180sxs for a whole lot cheaper than their wof/reg counterparts, the latter i wouldn't bother with as a starting point as there's immediate over capitalisation 

    Long story short, is it once they are off the road that unless you rereg then you're stuck with trailering and no hill climb/on road events? The Log books and authority cards path don't enable you to achieve some sort of road legalness once dereg?

    Dunno if this belongs here, but seems best place. I'm itching for a track hack and trying not to blow the bank, the opportunity for better/cooler cars is significantly higher (read cheaper) with something that it dereg. If my aspiration for motorsport is pretty much limited to track days, drags, and hill climbs is this a viable route, really my issue is how can i pass scrutineering in these scenarios with a car that doesnt have a wof. Is the path of least resistance rereg and cert (might not be economically viable), or is there another route where a car can be dereg and appropriately built (msnz spec cage etc) and somehow receive the correct authority cards that allow it to be driven on road for the purposes of an event (hillclimb, not to/from) (also how does one pass a scrutineering in this scenario for any event - provide evidence of msnz spec everything at every race?)  - i am going in circles a bit on the MSNZ website which as I read it says cars need a wof and a registration is needed in 8.1 of sched A

     

    basically just want to set off on the right track and viability of a dereg rolling body or not really determines which direction i will go
