Hey Guys, probably sick and tired of my questions, I’ve got a mate that’s just totalled his 350GT, engine bay was untouched and al is in working order, he will give me the engine for 300 dollars, which seems like a pretty good engine, he’s only done like 60K so far so it sounds pretty good. I know the installation will be a large cost but will there be many complications, I know the ECU will need to be swapped out, but is everything else in the car fairly similar? if anyone has done this before let me know.

Cheers.

You'll have to replace and splice the loom and plugs with it. It's not as easy as swapping the motor in.

The you have the issue of the 4spd tranny vs the 35 which runs a 5spd, which might mean headaches.

All in all, it's better off to sell up, and buy a real vq35, it's going to be cheaper too.

Lots of headaches. You would need to swap every ecu in the car along with the 5 speed auto. Better off going 6spd manual and a Haltech with the 3.5 conversion imo.

There are more differences than you would expect.

No purchases have been made, just asking, I’m not a mechanic, so I don’t think it’s unreasonable to ask questions. Obviously I’m just curious and if cost outweigh benefit than I will not continue to look into this. I don’t see a problem with being curious, and as I mentioned I AM NOT A MECHANIC! If I was then I wouldn’t be here would I?? Just something to think about before hurling your abuse at me. I have little to no car knowledge, hence why I am asking questions so I can learn and hopefully help others one day.

I bid you good day Sirs.

As far as this thread goes, there has been no abuse hurled, what's your damn problem? We were only offering advice like you asked for... And it has all been asked before.

I AM NOT A MECHANIC!

I fix these cars for a living, and yet here I am, helping an ungrateful V35 owner yet again...

      R34 engine swap Rb25de neo to s1 Rb25det

      By WMDC35 · Posted

      If you've wired up the coils & injectors properly, & have the neo CAS loom for the trigger, it should all work. The VCT works the same way so just different plugs between s1 & neo. Assuming DBW if no IAC. Don't bother with the stock boost solenoid with g4x.

      R34 engine swap Rb25de neo to s1 Rb25det

      By GTSBoy · Posted

      THERE IS NO IAT SENSOR ON ANY SINGLE TURBO RB. And the one on an RB26 is not for "engine control" - it's really too big and too slow and is only used for over-temp alarming (as far as I can tell). Anyway, you don't have one. You want/need one for the Link, then you need to buy one, find a spot for it, and wire it in. You do know that the stock boost solenoid is not capable of "control", right? It is merely on or off, for the low boost (5 psi) and high boost (7psi), which the ECU enforces mostly based on gear. The stock solenoid is not for PWM control and is not plumbed up in a way to provide it. If you want to control boost properly, then you need a proper MAC valve. And yes, you can wire either of them direct to the ECU. Well, I assume you can - I don't know what the boost solenoid pins on the plug and play Link are capable of. They really should be as capable as any normal Link - but seeing as it is plg and play, it might be limited to stock functionality. Read the doco.   You really do just want to plug stuff together without understanding how it works, right? I can't help you there. I don't know the plug types or pinning on half the stuff you're asking about. If I had to do it I would sit down with the wiring diagrams, the car/looms and a multimeter and work out what is what.

      Factory oil temp sensor in a RS4V without gauges?

      By GTSBoy · Posted

      Light should be a pressure switch, not a sensor.

      The pressure light likely has a different sender to a pressure gauge, its been too long for me to remember for sure. Just have a look for another sender down near the oil filter. If you are confident in your rewired pressure sender reading correctly, you can be pretty sure it is just the dash light's sender failing, it is a pretty common thing.
