Just did the rb25 conversion into non-turbo r32 as seems to be the rage lately. Everything is done now and car is running even better than expected however after about a month of driving im noticing that the car doesnt seem to want cruise at say 60 k's and will very slowly loose speed, then when i put my foot down it is slightly unresponsive untill all of a sudden there is a small clunk noise and off it goes accelerating again. I think this may be a diff problem but there is no whines, launches are still fine and normally after about 15/20 minutes of driving when the car completely warms up this problem seems to either minimise or go away all together. Any idea's as to what this could be?? A new diff is on the to do list but i dont particularly want to be looking at this till late this year. I'm not sure if this is important either but I am running the rb25 gearbox and using a exedy heavy duty

cheers

    • 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.
    • 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.
    • 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.
    • It would be nice to see the result, but instagram is a click too far
