hi all, hope the title cought your attention as ive got afew question to ask that need to be answered.

my situation is that i have a 68' chrysler valiant and im looking for that 'woah' factor for the car whilst being unique and having the ability to race. and seeing as everyone has converted to efi, super or turbo charged the sixes, converted to hemis or v8s, my thinking is what better to do that to dump an rb26 in :P

the questions i have mainly concern the ecu and wiring for the motor. in regards to the ecu i figured i could take the car to motec and get them to make something up for the motor to make it work but what can i do about the wiring loom? im guessing that i cant just hack it off so what are my options?

also, would it be possible to get some dimensions of the motor so i can know where what will sit? im already aware that the transmission tunnel will need to be modified to fit the gearbox and im ready to modify the chassis to get rid of the torsion bars to make clearance for the front drive shafts but i have to figure out where the shifter is going to sit and if im going to have to mod the firewall along with tranny tunnel.

basic engine mods such as removing the a/c and p/s wont make the motor not run either will it? im hoping to keep it as 'old' as possible.

and finally (for now), what is the best and cheapest way of obtaining the motor? buy it itself, or a half cut, import a half cut or what?

any help appreciated, thanks

sime

as soon as i buy the motor some time this year, ill take as many pics as i can, but in the meantime its all measuring and prepairing. the car currently weighs 1200kg with the driveline and im hoping the skyline block will be less weight compaired to the cast iron 6 thats currnetly in there but i wont be complaining either way.

lol, and as for tokyo drift. im putting front drive shafts in because i want an AWD, to me nothing compairs to taking a corner at 80km/h and g-force slamming your body back into your seat...especially when it leaves behind a brothers (72') charger with a viper v10 :D

but yeah, like i said. i need to figure out how the wiring loom issue will work ect to make sure the car will start.

lol, dont get too excited. this is my second project, might end up keeping the original one as a daily and making this the weapon, basically the same spec but afew years newer, bit more areodynamic and way more space under the gaurds for suspension ect.

the bodys the fun part for me, wanna paint it like a gtr, with the gtr badges and maybe the wheels if it looks half decent, but it wont be done till some time at the end of next year. so dont be holding your breath for a finshed product.

heres what a complete version looks like. dont get the wrong idea, when its not built like a pimpin' roadster it comes up nice.

Add 200kg's for the motor & turbos etc (from memory)

And then the g'box is 70kg's... :P

I'd be looking to get a RB25 box in there if at all possible.

So heavier than a gts-t, lighter than a GTR

Wouldnt be too bad, just some custom fab engine mounts. Use the full RB26 loom and then adapt to suit IMO. You might have issues with the dash gauges, but just go custom perhaps considering what it looks like :)

I don't want to egg you on, but I used to go down to Warwick Farm and watch the Geoghegan brothers in theirs = mad

Colin Bond was a nice guy too, even if he was driving a Torana. hehe

all i need is someone to say "it can't be done" that always gets my determination going.

I think doing the conversion and making it only 2wd would be very achievable. RB25 box, rb26/rb30 engine. wiring isnt an issue as you could even use the entire standard loom and just adapt it where it needs to be.

Now making an AWD charger, thats a little more complicated. You'd have to retain everything from the donor car. The only way I think such a project would be possible would be to modify the charger body with a tube frame support that would either be removable from the main chassis, or later welds to it.

I'd build an entirely custom tube frame chassis and then go about transfering the entire driveline from an R32 GTR. I cant imagine walking away from that project having spent less than 100k. The car would be legal under ICV rules if built correctly.

I bet you $50 you can't do it.

You can still get the older 4 and 2 door 'pacer' style shells pretty cheap. The chargers are now a bit on the pricey side.

Got to love the steering box chasis rust too on the chargers, one of my first cars VK with a 360cui :)

definately thinking 2wd drag car...4wd...thats left for the complete nutters to tackle...im only 1/2 way there.

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
