Hey guys I brought a r33 a little while ago and have converted it to a n/a. It was fairly easy although it's now running low compression etc. I still have the turbo ECU in it as the car is running alright. Car is having some trouble starting but have been told that could be fixed if I get the car tuned? Does anyone know what it would take to have the car running decently. I am 16 so putting the turbo back on is pointless as I wouldn't be able to drive it. If anyone could help me that would be greatly appreciated.

As stated above, stock ecu and stock injectors,

I think you would need some sort of engineering certificate when trying to register a turbo charged car as a non turbo? Emissions testing, exhaust pollution and all that kinda jazz? Im just guessing here...

NSW has power to weight ratio of <130kw.
Turbo ban was lifted 6 months ago. You can drive turbo in nsw if it is under 130kw which the gtst is not. So i guess you have to convert to n/a and try get it under 130kw per tone. Which i think is what will happen if you convert it to rb25de. Seems like a f**king hassle, i'd just buy a gts if i was you and sell the gts-t

if its in nsw it doesnt need engineering, it just needs a blueslip, as its no different to changing it to the rb25de that came in the car standard as well. then its registered as a non turbo r33 as if you bought a non turbo one. if its around sydney and everything in the car is legit and road worthy i can help you there provided you dont mind bringing the car to hurstville, if its a rubish car, rust, lowered, loud, dark tints, huge wheels or anything like that then i cant help though.

^ if you're in nsw. This is 100% correct.

Any type of engine conversion that the make of car came with from factory needs a blue slip and change of engine I.D on the rego papers. And that's it.

There are also small loop holes when you really start looking into engine conversions of other makes. It's actually pretty cool some of the combos you can do.

    • Waaay ahead of ya....(evil laugh!!) Will show the fitment and spec details later when it isnt as rainy !
    • Thanks Dose.....    I appreciate it!!
    • I'll probably be putting the shit box back on the dyno again soon, I want to dial in the closed loop boost control properly. I'll have a camera facing the car/motor for fun too. Just note, there are essentially 3x 10AN inlets going into the catch can and 1x going back to the intake pipe. Most of the time the catch can "return" to the sump actually is the crank case breather, pushing air out.
    • I have the R3C with a Nismo slave and by no means does it behave like a stocker, it ain’t THAT bad. On take off just give a bit more throttle than you would say a coppermix and it’s fine. It will not slip though.   
    • Okay. Final round of testing done. Got a friend to hook up a fancy scanner to the car and we also ran some compression and leakdown tests, she is healthy.  The MAF was definitely the culprit. So for future reference anyone with similar issues that find this thread. I suggest the following steps, in order of affordability:   Check your spark plugs for any fouling, replace plugs if they are bad or re adjust the gaps making it narrower (0.8mm would be good). Check every coil's resistance with a multimeter. It can be done by probing the IB and G pins on the coil pack. Resistance should be around 1.4 (+/- 0.1) Ohms Check the MAF. If you have Nissan connect or a good scanner with the 14 adapter it should allow you to see the voltage on the MAF reading should be around 1.1 - 1.2V when car is idling. But if you don't, buy a new MAF from Amazon and test, then return it. (For instance, I got a Chinese one for $40 that was reporting 1.3v on idle). If you still have scanner, you can run tests on the injectors to see if they are working, just remember to unplug the fuel pump fuse/relay and have no pressure on the line. Then listen for the noises that the injectors make. Clean/replace injectors as needed. Once you find the issue and fix, order thousands of dollars worth of OEM parts to refresh unrelated things (Optional)   PS: Thanks to the absolute legends of this forum for the responses and help to someone that went a bit over their head.
