hahaha yeah for sure rob.

No updates for a while, sorta lost interest and drive for a little while as i had no idea when the computer was coming. But it left yesterday and should be here today. Hopefully fire it up for the first time tomorrow afternoon. Take it down the coast for a tune next week!! now im kinda of excited again.

Rob i got ur PM i will look into that, cheers.

UPDATE:

IT LIVES!! Fired it up last night, built up fuel pressure, turned it over and it idled like factory.. well it hunts a little with the blower and is a little rich... A test drive and some street tuning tonight.. Then a trip down the coast to be dyno'd.... It sounds unreal!!

Can forsee a few small problems with it... the rubber seals where the funny lookin manifold splits may leak.... Still have to put the engine damper on the calm it down... with the blower mounted so far to one side it ends up moving quite a bit, Fuel pump is farken noisy!! but i knew it would be.. mounted on the boot floor that now has no sound deadening..

All thats really left to do is pretty up the interior and do the cage... these are trivial though...

Well everything seemed to work out perfectly. It made 5psi from ~6k through to 7.2k where it just started to max the injectors out at 335hp@rears and stupid amounts of torque... car is very stupid to drive and overall im absolutely stoked... to take it any further id have to put bigger injectors and lower the compression, easy enough done... but it will do "for now"...

ok well all worked out ok... kind of... couldnt manage under a 13 to start with but then we pulled the air cleaner off and played with some tyre pressures and the car dropped almost a second...

it managed a 12.42@112mph with a 1.7 60ft time

It wont change from first to second with out completely back off so it is loosing heaps of time there.. it kept going faster all night but andra kicked it off once it ran under 12.5 cause i didnt have front runners...

So i sourced some front runners yesterday wheels and tyres and they should be here by the end of the week...

Now i just have to sort the gearbox,, we may take it out for some more testing after power cruise before deciding which way we will head with the gearbox...

Options are speak to the guys in the states and send the valve body from the current gearbox over there to be modified, have a custom auto computer built for it and buy a big power handling rebuild kit for it.

And the other option is to make a Fully manualised C4 or turbo 400 bolt up... Either option is going to be really expensive... Im leaning more towards a built turbo 400 as parts seem to be cheaper for them and they are fairly cheap to get a ahold of second hand.

But this still means i will need to modifiy the drive shaft again and get another custom stall convertor built...

And at the moment i have zero cash... just waiting for the GTR to sell and then we'll see where we go from there....

More research is being done into a methanol enrichment system as well.... I want more power.. but first we have to get it down the strip with no headaches..

      Blue slip

      By GTSBoy · Posted

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.

      Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?

      You just need a different blue slip shop (preferably one you regularly use as a mechanic), and make sure the coil overs are as close as possible to standard height

      Ethanol Content Sensor - Always at 11%?

      By Duncan · Posted

      yeah the sugar refining companies were pushing for the same in Oz originally, all fuels were going to have 10% ethanol to make them "cheaper" (noting, that the loss in l/100 might be greater than the decrease in price). I guess they won that fight in Canadia
