I had my re5 built a few months ago, the valve body upgrade was imported from the US, thinner steel plates were laser cut so more clutch plates could be added and Dominator custom made me a 3000 stall converter on their 5 axis mill. The re5 is a much weaker box compared to the re4 (so I have been told) but this is holding the 250awkw I am pushing through it at the moment and is still very drivable. I had to disconnect the solenoid for the stall lock up clutch as it couldn't handle the power lockup the ecu was trying to make it do. (It locks constantly while in tiptronic mode.) I have fitted a switch in the dash to drop 12v onto the solenoid so I can lock it up still on the dyno.

I'm interested now to rip out the auto ecu and switch the solenoids manually, anyone know if there is such a kit for the 5 speed yet? If not I will have to design something.

im not a new at this mate i did searches, didnt find much on upgrading steps for autos. Just beacuse I drive it daily that doesnt mean i dont want it to be powerful. im just not going to thrash it like i would on a circuit. This being an auto performance thread i was hoping for advice on performance for my auto. And even tho timing belts can alter engine performance its not why i spoke of it at all, reason being was while im changing that i was wondering if anyone had ideas that could be done at the same time to save time/money performance wise. I'm changing the belt due to noise, these imports are known for having false odo reading so im doing it early to be safe.

Im not looking to learning about autos exactly, never modded an auto so i want assistance on mods for power gains for an auto. I dont want change my turbo for a garrett anything as yet, surely people have decent power without hurting the ceramic too much. If i knew what to do i wouldn't be asking. Anyway sorry to intrude mate ill seek advice elsewhere.

Cheers!

Hey mate, wasn't trying to have a go, but by the way it sort of came across like you actually didn't know to much and like so many people out there just gave a what do i do to get "a daily street car that does fast times".

I don't have a problem helping people out on what mods to do if they know what they want and want to inform me and other what they are trying to ask for in terms of engine, or drivetrain, or electronics or whatever.

There is so much stuff out there in this site it is rediculous, so thats why i said in my opinion go 30 bottom end, 3540 turbo, blah blah blah. You never actually said what you would like to do or budget. The only thing you said is that the car is auto. How is anyone going to give advice on little information.

Well you can work out the engine part, but being the auto thread, It depends what you want for power output. The biggest and easiest thing would be to get a shift kit. A simple stage 2 shift kit. This will help stiffer shifts and any flaring between gears and prolong box life and help it cope with any extra grunt. You need a bigger oil cooler, or well an external to the standard radiator cooled cooler.

Once those mods have been done and don't expect to pay more than $500 with everything fitted(if you can't do it for your self) the next place to go from there, get a higher stall converter. Try for about 2800 or there abouts, depending on turbo setup. That will let the engine to increase revs higher and get greater torque to the wheels, then it'd really start to cook. With 250-300rwkw and just that setup, expect 11's or at least low 12's and your box could/should handle it.

The rest is up to you.

I need to find a bigger stall as my stock 2300rpm stall just doesn't cut the mustard with a highflow that isn't making any serious boost until 3500rpm.

I have heard that 34GTT's are 3000rpm stock.. is this true?

What other bolt-up options are there? (car is a series 2 C34 Stagea, pretty much same box as 34GTT)

MV autos do a high-stall, coincidentally I have a whole setup for sale. :)http://www.skylinesaustralia.com/forums/topic/349136-eoi-built-r34-tiptronic-transmission-by-mv-autos

I need an AWD box and cbf swapping internals :P (box is still going strong though and was squeaky clean when we did the welsh plug mod).

How big is the stall you got from MVs?

I've got a 2800rpm mall stall from All Fast if your keen... I'm also located in Perth :)

Interesting but I don't think it will be high enough, I think I'd need 3000rpm to get it on to boost (or put my 3L in the wagon heh)

Can you PM me what it cost to get that stall built? Cheers :)

Also, is the torque converter the same between R33 and R34?

Well went down to the Nostalgia Drags at the Perth Motorplex on Sunday... a 1pm start time wasn't the best for the car (considering the 36 degree heat) but it was still a good day. I had the car set-up to get my ANDRA licence (tailshaft loop, harness, isolator switch etc.), but when I got down there, for some very stange reason my race slicks and mags were rubbing on the guards - even though I have used the exact same tyres/mags in the past!

Anyways, car was pretty good all day considering I was only running the street tyres. Recorded my best time around 6pm when it had cooled down a little - 11.5 @ 121 mph, unfortunately street tyres only allowed 2+ second 60 foot time (I think it was around 2.1 - 2.2 seconds). This is with the car running around 350rwhp @ 15psi. Had planned on getting it tuned to 20psi the week prior, but didn't get my shit together in time.

Was a good fun day. Really want to break a 10 though (which I am very confident it will do once I get the slicks and some boost into it).

guys i'm from the vl side of the fence, just spent over 3k on my auto to freshin it up, looking for alot more power, my auto is only rated around the 300kw mark, and wanting to search different options, i don't want a glide and more gears the better

these RE4R03A how much does a build to take the 450 kw mark cost to build, and does anyone know about them in aus, or where to buy the parts ? thanks

No hater of VLs. KEAS and MV automatics know these boxes well. I have a strong recommendation to Bob Grant Automatics. Where was yours built?Most of my quotes aimed at 350kw have been large.

G&z automotive built mine! All keas parts, I have a 4 speed vl box with the works! Power is rated between 300 and 350, after taken him for a drive he said your driving style no more than 300, looking at having that on low boost and close to 400 on hi! And looking for a cheaper option than another 4k any1 had any luck with a c4.

Stop start traffic defines Sydney. Mine isn't a daily. The Ford version F6 4.0L6 and ZF 6 speed auto was a great combo. I think my rb25 with gt35, re403a trans, may be less so. One a idea is using stall on the converter to stall it into the turbos sweet spot. Accelerative performance in drag not circuit also relies on area under the curve, an auto is just floored on the throttle, while a manual loses thrust during the shifting. Plenty of fast manuals. It's preference and what you want to do with it.

    • I have been being VERY quiet about what you're alluding to, as it is something that ticks me off... The number of cars from factory that run coil overs is HUGE! Most of them these days do... The other part that annoys me, is people saying "Well all the incabin adjustable suspension is illegal by blah blah blah"... If that's the case, then why can I buy a car brand new that can do it if, FULL STOP in cabin adjustable suspension is illegal...   Also, I could just chuck some aftermarket shocks in my car, throw the stock springs on, after my blue slip, dump my super low springs back in. Same shock and spring style setup... Hell, they could also be the same colour springs etc.     I'm voting, BlueSlipper didn't want to touch the above car for some reason. Whether it be some sort of bias against the car, the owner, them maybe having previously done dodgy shit and now they're being super careful in case they get slapped in the face by the Gumbyment again... Find a new blueslip place.   And can confirm as you had said, yes there are holy bibles of vehicle heights, and all sorts of other suspension stuff. Heck your run of the mill mechanic, and tyre shop has access to all of that stuff. It's how they do wheel alignments...
    • Funny story Heading to Sydney this morning on the HWY there was some slow traffic, so I gave it the beans and midway through my overtaking "power run" I lost all power It seems that I missed a hose clamp,  and the MAF and filter went WiFi To make this more problematic, the little tool kit that lives in the boot, is sitting in the sun room at Goulburn......LOL Luckily for me I found a bit of steel on the side of the road that could be used like a rusty and bent flat head screw driver to tighten it up enough that it got me into Sydney, it is now all tight like a tiger with the aid of a 8mm socket Note to self: Use my brain and double check stuff, and always keep that little tool kit in the car for when I have a brain fart
    • Oh, and as for everyone with their fuel economy changes, I switch between E10 and 98 in the company car. Even do when I had personal cars that could run on E10. You know what changed my fuel economy in any noticeable way? How I drove, and where I drove. Otherwise, say on full tanks of just back and forth from work only (So same trips, same sort of traffic), couldn't notice a difference that I can correlate to the type of fuel in use. In the current vehicle, that's over 42L of USABLE fuel. While 98 is all "more energy dense", it also has higher knock resistance as it takes more energy to get it to ignite too. The longer hydrocarbons, typically more tightly bound. So running the same ignition map, can also produce less power, if there isn't enough time to get it all burnt through properly, as yep, the flame propagation speed is different from lower octane fuel to higher (Higher has a lower flame propagation, due to the more tightly bound and harder to self ignite funs. This is also typically where, a vehicle that is designed purely to run on 91 (Whether it be E10 or normal 91) usually sees absolutely no real world difference in fuel economy for the normal man, woman, or dog.
    • We've got some servos around me that have 91 with E10, 91 (no E10), 95, and 98. At those stations the change from 91 E10 to 91, is typically around 8c/L.   But lets not get started on the price of fuel in Oz. It's ridiculous. All the service stations around me, bar one, the price of fuel has been over the $2 mark per litre for the cheapest, 98 being around $2.45. That one service station is a CostCo, fuel from it comes from the same refineries, and makes no pitstops, it runs great, including the 98. In fact, I've had no issues on CostCo fuel, but plenty of issues at other stations!. The CostCo fuel, was $1.65 roughly this week for 94 with E10. $1.88 for 98. Servos directly across from it, $2.10 for 91 E10, and $2.48 for 98. The part I had to laugh at? If I drive multiple HOURS away from Brisbane, say out near Nanango, or Kingaroy, or even out to Goondiwindi, the price of their fuel, is the same as what it is at the CostCo... Oh, and that BP servo at Goondiwindi is HUGE and goes through epic turnover of fuel, so it's not sitting there for weeks going to shit. And what blows me away, my mate is one of the people who drives the Fuel Tanker all around QLD, delivering to all those places. At the same company his previous role was doing the "local haul" deliveries... Same truck, same driver, same pickup point it all comes from. So you tell me, how the hell it is 60c/L CHEAPER for fuel, when nearly all else is equal, except they require a B-Double to drive half a day out of Brisbane, and half a day back, every second day, compared to the delivery that can be under 30 minutes drive from the fuel pickup point... Not to mention, go five blocks down the road, and Ampol to Ampol will vary 30c/L... And I've had this conversation with my mate... The way it's priced, is just typical, pure and utter rubbish... He also does runs from Brisbane, to all over QLD, down to Newcastle, Sydney, Nowra, Melbourne, Geelong, and even out to parts of the NT depending on the companies needs. His main stuff is all the longer distance away from home for a few days at a time, then when he's back, he loves to just pickup extra shifts wherever he can in whichever truck, hence all the weird different places.   Oh, as for getting E10 into all the fuels in Australia... It was very quickly highlighted, that we don't have enough biomass available to use to make E10 sustainably like they require, and it would dramatically cut into our, and the worlds food chain supply...   I vote we all just start running on liquid methane gas... Plenty of that just getting tapped off at tips from underground decay... (Note, this is pure just stupid commenting. I could very easily highlight the reasons its not a good idea especially on scale...)
    • Am I correct in assuming that the R35's are getting the classic skyline haircut off the odometer?  Quick search on carsales, there are 33 08 and 09 GTR's for sale, only 2 of them have more then 100,000km's on them (116,075 and 110,000 respectively).  And somehow there are about 25 for sale with around 60,000kms? Looks like the classic skyline haircut to me =/
