Evening fellow R chassis enthusiests.

I'm currently in a back and forth discussion with myself going further with my 34 gt coupe 

Overall the car is a genuine example of a clean, well maintained r34. Not show car spec by any means but presents and drives great.

question is, given that prices are going throught the Roof (nearly tripled since i bought my first 34 GTT in 2015) and have no signs of stopping anytime soon..(US market bla bla bla)....would it be less frowned apon now to swap the drive train out for gtt spec?  I just don't want to get caught out selling what I have now and not being able to purchase the better model because there is none for sale or because theyve slipped too far out my price range to quickly..

Sorry for the rant...just can't seem to make up my mind for myself

The difference between the (very very few) on carsales looks to be about 10K.

Will 10K cover a gearbox/ECU/Engine swap/tune?

I reckon not, not really, and there's other issues (diff, sensors, also the hassle of doing this).

I say buy that cleanish 20K R34 GTT

Then sell R34 GT off to a P plater.

Future you would be happier.

I appreciate the feedback, and everything that has been mentioned so far has been going through my head.....aside from swapping in an 8, that's just not gonna happen.

As for the cost, I can get ahold of essientally a complete half cut GTT for roughly 5k minus the tailshaft and rear subframe/diff ect. 

And that's where I'm at an impasse.....I could probably get 12k for the GT as it sits....+5k for the half cut I have ready for the swap, adds up to 17k - Just shy of what's needed to buy a decent GTT and that's if there's any for sale at the time....there's becoming less and less for sale, the want adds are increasingly outweighing the for sale adds.

A GT converted to a turbo is not a GTT.

A GTT front cut is good spares for a GTT.

A gap of a few grand between the cost to build "a half-arsed never gunna be a real GTT" and just buying one, does not seem like a saving worth making. If the GT had a whole pile of parts on it that you couldn't bare to part with, you could still bring many of them over to a freshly bought GTT.

An engine conversion on a GT might as well be "a bloody good one", rather than just slipping in the GTT motor. Why not go for broke if considering a transplant? No-one would consider a GT with a V8 transplanted into to it to be a bad thing. Or a 20B. Well, OK, there's reasons to not like putting a rotary into anything. But it would still be cool. Whereas dropping a 25DET in it is a cop out.

I understand where you're coming from, in the sense that at the end of the day it will still be a GT no matter what I do to it. I'm not trying to pretend it will be somthing it just isn't.

And as for converting it to a ford/Holden/wankel/jz just isn't even a thought in my head, it'll be a neoT/rb26 or i just wont do it.

The whole point of this post is to see if people may consider it to be a financially realistic option given how rapidly these cars are jumping in price, but I've gotten the general vibe and now I'll just look to try put a few extra pennies away as quickly as possible before the inevitable happens, cheers

If it instantly appeared with no stress, and cost $0, you'd be 3k ahead. But I've been down this path and it doesn't cost $0, and doesn't create 0 stress.

Realistically is a stock R34 GTT worth 20K? No not really, you can buy plenty of better (stock) cars for that money. At some point "sensible" is not applicable to these things and its all $ -> Personal, subjective enjoyment

If you want that car to be a turbo.....just add a turbo. Pretend that the GTT never existed (except for perhaps needing a gearbox, diff and brakes from one!) and just treat it as if it was any other NA RWD car that didn't have a turbo option.

The above suggestion is also slightly sarcastic, because I also generally tend to advise against that choice when you can just go out and buy a turbo version of the same car anyway. But it's a perfectly fine way to turn a GT into a turbo car.

Otherwise, what Greg says above is all true. There is no financial sense in any of these ideas. So just choose how you wish to piss your money up against the wall and get to it.

@Kinkstaah as a former workshop mechanic and tyre fitter, can confirm that 20k will in fact get you in the seat of some really fun cars, but for me it's more sentiment than anything, I genuinely enjoy the way these chassis' drive and handle

Make up a list of all parts that are different/ better between the na and turbo model, then work out what each one will cost to buy and install if it needs to be upgraded. Then factor in more costs for when things don’t go exactly to plan

then think about the legality/ insurance side of things. Will your insurance cover a turbo converted car in the case of an accident? 
i personally  would not do it unless you have some strange emotional attachment to the car.

My 2c

This is only ever worth it if you skip the stock GTT step, e.g. put in a forged RB25, big highmount turbo, big aftermarket brakes, etc etc

Install parts that if you had a stock GTT, you'd end up replacing anyway. 

Go big or buy a real GTT and leave it stock.

Best advice given here so far. The expense of converting to stock parts then later wanting more power and paying twice is silly.

I agree with you 100% but to do this legally in my state (SA) I have to get it as close to GTT trim as possible firstly to pass inspection

Not strictly true. You could go as far as an engineer will let you go. Vehicle Standards just have a preference for such conversions as this to be "to the same spec as factory" because they'd prefer not to have actual modified cars running around. But they will approve a car that has gone straight from NA GT to GTTish + mods if they have given you approval to go ahead based on your application (and the engineer's OK, of course).

    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
    • When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
    • So I found this: https://www.efihardware.com/temperature-sensor-voltage-calculator I didn't know what the pullup resistor is. So I thought if I used my table of known values I could estimate it by putting a value into the pullup resistor, and this should line up with the voltages I had measured. Eventually I got this table out of it by using 210ohms as the pullup resistor. 180C 0.232V - Predicted 175C 0.254V - Predicted 170C 0.278V - Predicted 165C 0.305V - Predicted 160C 0.336V - Predicted 155C 0.369V - Predicted 150C 0.407V - Predicted 145C 0.448V - Predicted 140C 0.494V - Predicted 135C 0.545V - Predicted 130C 0.603V - Predicted 125C 0.668V - Predicted 120C 0.740V - Predicted 115C 0.817V - Predicted 110C 0.914V - Predicted 105C 1.023V - Predicted 100C 1.15V 90C 1.42V - Predicted 85C 1.59V 80C 1.74V 75C 1.94V 70C 2.10V 65C 2.33V 60C 2.56V 58C 2.68V 57C 2.70V 56C 2.74V 55C 2.78V 54C 2.80V 50C 2.98V 49C 3.06V 47C 3.18V 45C 3.23V 43C 3.36V 40C 3.51V 37C 3.67V 35C 3.75V 30C 4.00V As before, the formula in HPTuners is here: https://www.hptuners.com/documentation/files/VCM-Scanner/Content/vcm_scanner/defining_a_transform.htm?Highlight=defining a transform Specifically: In my case I used 50C and 150C, given the sensor is supposedly for that. Input 1 = 2.98V Output 1 = 50C Input 2 = 0.407V Output 2 = 150C (0.407-2.98) / (150-50) -2.573/100 = -0.02573 2.98/-0.02573 + 47.045 = 50 So the corresponding formula should be: (Input / -0.02573) + 47.045 = Output.   If someone can confirm my math it'd be great. Supposedly you can pick any two pairs of the data to make this formula.
    • Well this shows me the fuel pump relay is inside the base of the drivers A Pillar, and goes into the main power wire, and it connects to the ignition. The alarm is.... in the base of the drivers A Pillar. The issue is that I'm not getting 12v to the pump at ignition which tells me that relay isn't being triggered. AVS told me the immobiliser should be open until the ignition is active. So once ignition is active, the immobiliser relay should be telling that fuel pump relay to close which completes the circuit. But I'm not getting voltage at the relay in the rear triggered by the ECU, which leaves me back at the same assumption that that relay was never connected into the immobiliser. This is what I'm trying to verify, that my assumption is the most likely scenario and I'll go back to the alarm tech yet again that he needs to fix his work.      Here is the alarms wiring diagram, so my assumption is IM3A, IM3B, or both, aren't connected or improper. But this is all sealed up, with black wiring, and loomed
