I own an auto 1998 r34 gtt and I'm thinking about getting a larger turbo (roughly 350 hp rated). With manual cars the clutch would need to be upgraded but would anything need to be upgraded with an automatic ??

Any replies will be greatly appreciated

Cheers, angelo

Yes, you need a shift kit and a transmission cooler for that sort of power.

What sort of turbo is it? Usually people say the brand or part number, not just the power it can make. I hope this isn't an ebay chinese copy of a real turbo...

Okay thanks for that , really appreciated ! :)

And I'm not sure yet. It's out of some guys totalled gtst who said it was making that much power. It's a gumtree add and I'm trying to figure out weather to buy it or not. It sounds like it's the stock turbo high flowed but I'm not 100% sure

I don't like buying S/H turbos unless I can hear them running, but if it's stacked at least there is a legitimate reason for selling.

Depends where you go, MV Automatics in Adelaide apparently do a valve body swap service if you are mechanically minded, or get your mech to look into it? If you had a location I could possibly help more.

At a guess, the shift kit would cost $600 - $1200 fitted including fluids.

A trans cooler is $100 odd and can easily be mounted by removing the front bar. You should be able to manage that yourself, or find a handy mate and offer him bourbon.

I'm in Perth. Also thank you so much for all the help !!!

Also even if the turbos broken I don't mind. The guy doesn't know too much about cars and he's selling me the turbo, some injectors and an electronic boost controller for $400. Bargain of the year :D

So you'll need an aftermarket ecu or Nistune chip at least, a bigger AFM, possibly some oil and water lines and new exhaust and preferably a manual conversion!

also price for shift kit varies bepending on brand and if yo want a stage 1, 2 or 3 ect but just for a rough base line a stage 2 shiftkit for my old 31 skyline auto cost me 1290 fitted

I have gone from the standard shift kit to pretty much everything you can do to a R34, and the difference is beyond night and day. Absolutely absurd. I drove a stock one and almost laughed myself off the road.

You have two options

1) Stick with and upgrade the auto (no one really does this long term other than stupid me)

2) Go manual

I entirely understand why people driving stock Skylines pretty much go LOLZ AUTO LOLOLOLOLOLOOLO.

Talk to mv autos in Adelaide. I had a 34 box built full manual valve body converter etc for under $4000.

Manual valve bodies are absolute crap compared to an aftermarket programmable transmission controller. ;)

I ran 200rwkw through the Tiptronic and it was fine-ish. Then went 260rwkw+ and it was s__thouse -> converted to manual.

I'd suggest doing the shift kit early, should make the box last a bit longer. And the cooler. Plus anything else Scotty and Greg recommend.

(Also if you're spending little money on the turbo you will end up spending much bigger money on everything else around it. There's no cheap way out, really.)

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
