its 1:25 pm and im at work and i can still smell the odour from last night

Went with a power FC because it seems relatively well supported by tuners in this area . And it's fine for my power goals and mods.

Ah fair enough.

WHAT! thats sooo dope.
this thread get more amazing by the second.
are you going to lighten up the chassis at all?
and what about breaks?

Just spent the last hour readings this. Awesome thread man. I think you have me sold on the tomei expreme and the turbos. Was pretty set on hks before I read this. Keep up the good work man. Gorgeous car.

@rabbit - i have some EBC red stuff pads going in the brembo calipers in the near future , havn't installed them yet because i'm not ready to track this thing yet. And to be honest after seeing the way the ricers behave on the tracks around here i'm not too sure i will. Do you see the flipped Scoobie at Mosport ? and all the other ricers stopped on the track got out and ran around ON the track ? .

I'm thinking I'd like to try and find a mature club to join that can book the track for club use only so that the moron element isn't an issue!

Skyline track day? I would be up for it in about a week or so

The factory manifolds are the toughest (tubular a known to crack over time) and can be ported to flow really well, though tubular are better for that. Cost wise, there are better ways to make power than that. Ported N1 manifolds and outlets will be great for power even at 600whp. That's technically $1000 or more that can go towards turbo, head mods and other power adders.

There're lots of guys making over 500whp on factory manifolds and head mods, meaning they don't spend huge cash. The gains on the tomei bits aren't as good as what they cost compared to other mods.

Single turbo is the way to go. Less weight, less shuffle, less cost (most times), less lag, more top end, less clutter to work with.

Thanks bruizer. I'm not to sure on going the single turbo route (because i've already started my build around a twin) but definitely will look into getting my manifold ported instead of going out and dropping a grand on a tomei expreme. Think I'm still in love with those 7655's though and with this forum as a guideline I think even with my novice skill on cars and obviously the help of a knowledgable friend I would be able to save a bit of money by doing it myself.

Bruiser is right ..

But for me the cost is not a main issue , a few other things i like about the tubular headers is their ease of install , the cramped working space of the factory manifolds is a contrast to the easy access on the tomei headers , i installed the tubulars with 1 socket , i extension and a 3/8 ratchet handle and 1 wrench, the manifolds require alot more tools and time to install/uninstall.

In my particular application they cost alot more because I spent $600 having everything XMC coated(triple ceramic) to reduce underhood heat and inscrease spool speed and it does work very well.

These turbos are similar to the GT2860-5 garrets , they dont spool up as low down in the RPM as factory units but are at max boost by 3800 rpm and by 5000 rpm you better be hanging on to something , and that at only .75 bar.

I'd have to say that with my current setup i can have the complete passenger side of the engine dismantled in about 1 1/2 hours now. Thats worth a few extra bucks to me

way to rub it in ass,hole

[r33gtrrb26]

I would obviously be able to triple coat my stocks once I got them ported as well right? Pretty hot over here in Alberta too.

Indeed you could !

20th july , very late at night .

So its back from the skymeet over the weekend with my head full of all kinds of ideas from everyone elses cars . Car drove there and back ( around 400 klm ) with no problems , no leaks , no vices apart from when we stopped in traffic on the 407 and a horrendous metallic screeching sound came from the engine bay until i turned off the AC in panic . We thought it was one of the turbos blown with the impeller rubbing on the housing , but luckily it was a 12mm socket that had dropped down into the ac fan cage while i was working on it and was rubbing on the blades when the fan spun . SOoooo relieved hah !

So I figure its time to start the grind again , spent an hour fitting an airconditioner in my workshop so i can work without becoming saturated in sweat each evening .

I then decided to pull of the dash cover , glove box and steering column cover to expose the wiring loom and see what i was up against.

Someone had installed a Apexi revspeed meter in the old ashtray location that i wanted gone. Also decided to rip out the toll road card reader thing under the dash and the greddy boost controller and blitz boost gauge .

Talk about pandoras box , WTFARK wiring :-



By the time i had finished i had ripped out about 623452 miles of wire and cut through about 40 zip ties . Who ever had this car before had a zip tie fetish , i swear it was a cobweb of wires and took ages to trace and cut it all out. The loom by the ECU looked like johnnyfives brain . I ripped out all non factory wires leaving only the installed starter keypad / imobilizer module as id like to keep this gadget.

FInally the ECU loom looked oem-ish again :-



It's really un-nerving to find burnt connectors in your dash



this is about half the crap that was floating around under the plastic panels that i removed ... more of this junk to go though !



Finally the dash is de-flowered and its ready to have this installed :-



that will be installed over the next few evenings

Yeah, for a country famous for their electronics they seem to be brutal for wiring. My old R32 ( now DJ's car) had an even scarier snakepit under the dash. We pulled apart the console, found a massive bundle of wires and zip ties and was able to start the car by squeezing it. The car was accidentally hot-wired lol.

i just got my avcr in the mail too! not the black edition! you should post a diy for install

[cortexx]

will do - tonight if im not too knackered
