Grunta, I'm not sure about the ECU on the GTT vs NA on the Auto models. From my understanding you still need to run engine management? Someone might want to clarfiy that.

How much are RB25DE's worth for resale? I'm just thinking what the cost for you would be to Buy half cut, deliver it, remove old engine, install new engine, then whatever else still needs to be done after that; vs keeping your engine, even still removing it and doing internal engine work. I'm not sure exact costs, but would that not be rather close to that of complete engine swap? A rebuilt GT-V I think would be better than simply swapping over for a DET, if you're looking at removing the engine.

havent you forgotten to list pistons ? you need low compression pistons, otherwise using the standard high compression pistons that NA's have will just F*&k ure engine VERY quickly.. although i h

i have a 1993 r32 gts with a rb20det conversion. i bought it this way so i dunno whats been done. power seems sweet up until 5000rpm, where it seems to hit some flat spots in power from there onwards.

hey i just though i would go back a little bit and add something in, in relation to drilling the oil return line into the block a way of getting around this would be to buy an oil cooler and run the o

Well I'm almost ready to have it all put in!

Just waiting on FMIC and catch can to arrive, then need to try get a factory BOV or cheap but good plumback and pod filter.

I also believe that I will need a silicon aftermarket or factory induction pipe that goes to the turbo inlet...or can the factory one be modified to suit?

Also any recommendations for tuning places? I think Robin said he usually sends them over to APC, something close to slacks creek would be ideal to get it all done together.

How driveable is an RB25DE+T without having the tuning and timing adjustments done straight away?

^ driving it straight away without any tuning or timing would be highly not recommended.

ecu will be running nuts with all the extra air & shiet coming thru..

will a stock manifold from a R32/33 fit on a R34 neo?

Nathan man goodluck dude, im still contemplating the firgures behind the upgrade.

ETA on when your gonna' start ?

And how you gonna' get the car from the place your getting the work done to the tuning place, i dont think it will be driveable.

Yeah the figures can add up quite quickly, but it depends on where you get parts from. Keep a look out on ebay as well, I've seen some R34 Neo model turbos going recently, and even saw a set of neo injectors listed at $20 starting! Check the for sales here as well, always bargains keep coming up, and on NS.

I decided to see how I go with a Monsta Performance Delta Fin Intercooler. They sell on ebay for $350+$54, but lately they've done some starting at 1cent. I didn't have much luck the first time fighting over it in the last minute, but second time around I picked it up for $252 plus $54, for a full kit. For what it's worth I'll see how it goes.

I'll probably get it done at PerFourMance motorsport in Slacks Creek, pretty sure there's tuning places around there, it's like performance heaven down there lol Hopefully getting it from workshop to tuner won't be too much of a problem then.

Robin at Perfourmance said he usually sends them over to APC, which is about 1.9kms away. Then again, a brief search spat out some not so favourable results, so now I'm really not sure of where to go.

I'm still getting to know the places around Brisbane to get work done, so I'm really open to suggestions. I don't want to break the budget in labour, but I'd rather spend a little more if I need to and get quality work done..specially when it comes to the tuning of a RB25DE+t

I'm probably going to proceed with the conversion either before or after xmas. I want to take a trip back down to the Gong for xmas though, so that's why I'm thinking after xmas. Though I've got pretty much everything in or on the way except for a BOV and pod filter, so knowing me I'll get impatient and just get it done with :D

I've been thinking of options with exhaust as well, contemplated the idea of having a 3" mandrel bend (or 2.75"??) made up with resonators and a GTR Muffler if I can get hold of a cheap one. That way I can keep the factory look and stay quiet, and I figure that the GTR Muffler should flow well enough for my needs. I'm not sure what the weight would be like though compared to an aftermarket S/S.

^ thanks nate dawg.

other things im getting are brand new; fuel pump, intercooler,exhaust etc

No worries man

I picked up my Walbro GS342 on ebay for $145 posted from http://stores.ebay.com.au/PERFORMANCE-WORLD-STORE:

http://cgi.ebay.com.au/ws/eBayISAPI.dll?Vi...em=320308878704

They are super quick with postage. I bought it on a sunday, had it delivered to work, it was on my desk when I got there!

As for intercoolers, I got one of these Monsta Intercoolers on ebay http://stores.ebay.com.au/MonstARetailCentral.

For the price I'm willing to see how they go:

http://cgi.ebay.com.au/ws/eBayISAPI.dll?Vi...em=220294349334

They do one listing at a time starting at 1cent. Or you can choose the buy it nows, works out around $400ish posted. I got mine $304 all up in the end, it's a bit of a fight bidding for it in the last few minutes though.

Exhaust, unless you can pick up a second hand one, just get a custom one made up. Mr XTC might have a 3" catback for sale if he doesn't give in to doing the turbo conversion :/

      R34 Skyline climate control unit transistor

      By dbm7 · Posted

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.

      Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
