Thanks Dan. I'm not sure exactly what you mean about the Auto ECU actually being more trouble than the manual one but no worries - you've still answered my question so that's great. My simple way of thinking about it was that either way, the loom on my DE won't have the transmission related wires going to the relevant pins on the DET Auto ECU so those features won't get activated. And with the manual ECU I figured that as it won't be expecting any auto related wires anyway it will play happily with my loom's connections that all go to the external TCM. I just went back and re-read the +t thread you started back in 2004. Someone said that 'the GTT ECU goes a bit haywire as it understandably cannot detect any boost.' Nothing more was said about it but no-one else seems to have an issue with that so I guess it's not a real problem. The pinouts for the ECU do list pin 47 as turbo pressure signal but is that just for the gauge?

ECU for auto +t I've been looking at getting a NEO DET auto ECU to do a +t. I know there's lots more to it than that, injectors etc. but there's lots of info on that. I'm interested in my ECU options other than just a piggy back. From the service manual the NEO DET ECU will have the auto trans controller in it. My DE has an external trans controller so I guess there'd be some rewiring involved to ignore the external one. But can I widen my options and look at getting a NEO DET ECU from a manual and wire it to use the existing external auto trans ECU that's on my DE already? If this is possible it widens my choice as these ECUs don't come up often and it would mean a manual conversion later would be part way there. Could the chip with the fuel/timing data even be desoldered from a manual DET ecu and put in the auto DE ecu? Thanks.

Hi, I've been reading up on +t conversions here and elsewhere for quite a while now but I've got a question that I haven't had an answer to yet. On a stock DET manifold the turbo coolant returns into a nipple on the back of the inlet manifold. It's at the end of that ridged casting that runs the length of the manifold against the block just above the ports. At the other end of that ridged casting at the front of the engine there's a nipple which runs up to the bleeder. DET NEOs also have a nipple in the middle too I think for a rear bleeder. So ... is that ridged casting a straight through water channel that runs the length of the inlet manifold? My DE NEO doesn't have the rear turbo return nipple but I'm thinking that I could tee the return into that nipple at the front end of the ridged casting. Then I think I can tee the turbo coolant feed from next to the thermostat which is just beneath it. That way I'd have the necessary thermal syphoning. That's the theory anyway - be great if someone knows the answer to that question. Thanks.

Thanks for the welcome. I'm pleased with the GTR brakes, they definitely felt better than the originals although those were getting tired and I'd had to free them up more than once. They look so much nicer too than the slider type ones on the standard GT. I could probably think back and remember each R34 I've ever seen on the roads since I got mine - maybe a dozen. They are about though and see them at car shows. It always puts a smile on my face when I see another out and about. Asking prices for GTTs are typically £8K or higher and I think are increasing (tiptronic a bit cheaper). I'd have to sell mine first (non-turbo auto are worth much less) and be without it till something right came along. But chances of getting another yellow one are slim and I've become emotionally attached to mine LOL. Engine swap is another idea. NEOs are asking £1.5-2K and I might barely get back a quarter of that selling my RB25DE after. I'm happy to slowly gather the bits till I've got everything and then decide what to do. I can always sell the bits on again if I take a different route.

Hello. I've been lurking for a long time from here in the UK but finally joined up. Had my R34 since early 2010. It's a GT (tiptronic) and this site's often been a big help even though I've been a member of other UK sites all this time. A few basic mods ... Apexi adjustable suspension R32 GTR Sumitomo brakes all round Alloy radiator and Evans waterless cooling K&N intake Iridium plugs GTT standard exhaust from cat back 350 GT wheels Got some East Bear skirts to go on at some point too but not in a rush. I've also just acquired a turbocharger from a GTST and now going to see if I can gather the remaining bits for a +t on a reasonable budget. Looks like there's enough of you have done that and might be able to answer some of the questions I can't find answers to. Here she is ...
