Rb30E+T

[nismokiller]

Need abit of help choosing the right gear for my motor!

Its a RB30e r31 motor with roughly 140,000 kms on the clock

im after a turbo that would be appropriate for drifting , not after a lag monster, but nothing to small? possibly only want to run 14psi max im guessing for a standard motor with a new headgasket?

Also would i get away with drifting using a rb30 gearbox? or should i try and chase up a rb25 box or VL turbo box?

And would it be worth throwing a cam in it?

Sorry in advance if this isn't the correct forum for my questions, and thanks to anyone who has help on this topic!

cheers,

I have a ripper setup in my shed if you need one

I think your better off buying a rb25det i wouldn't be to confident In the 30 lasting long when having a turbo slapped on it then reving it's guts out. If you want to just go the 30 a gt30 serries turbo is prob your best option

I have a 25 neodet motor coming my way next week >.> it only comes with a engine loom and computer, if i wire up a push button start system, with battery and indevidual fuel pump switch, should i be able to start the motor with just the wiring that goes with the engine??

Nothing wrong with riggung up a turbo to an old 30E. Seen it done time and time again on engines up to 400 000km. 31 and VL guys do it all the time.

you should be able to find a complete stock rb25det for the price of all the 30et gear you buy. it will make more power safer and rev harder

[FordyR31]

Are you doing all the work yourself or paying someone? if the 30 is already in the car which it is its all bolt on. Blow a 30 and its cheap as chips for another

Yes, but you will have some fault codes. TCS/ABS at the very least. If you do not have the (ECU, not dash) boost sensor plugged into the engine loom, then a code for that too.

[nismokiller]

its engine loom only, i do have a r34gt-t loom to suit, but its butchered..! the motor appeared to run a IMPUL computer, how do i eliminate the fault codes without running the same factory loom?

[GTSBoy]

Nistune. Only masks them so you don't see them in Consult and don't get check engine light. If they cause any problems (and the TCS and boost sensor will both cause problems, especially with a bigger turbo and more boost), the problems wont be stopped, they'll still happen.

[nismokiller]

so if i fit boost sensor and TCS sensor that will allow me to run it without hickups?

[GTSBoy]

No. Not that simple. Boost sensor is easy. TCS system is a whole 'nother story. The TCS system has its own computer that reads the wheel speed sensors and actuates the TCS throttle butterfly (upstream of the engine's normal throttle). The TCS butterfly has a position sensor on it.

When you start the R34 engine up, the engine ECU looks to see if the TCS system drives the TCS butterfly closed then open (start up self check). If it does not see that, it raises a code. Also, if the TCS computer is not present, then the ECU will raise a fault code because of the comms failure. You can only have it all work if you have a functioning TCS computer, which will probably raise fault codes of it's own if you don't have all the wheel speed sensors etc.

You can use a Nistuned ECU with a Stagea image in it (no TCS in Stageas) but my recent experience with doing so is that the automatic transmission Stagea images that are available cause driveability problems with manual Neo cars.

Im about to do a TCS delete on a 34 that we are converting to a plazmaman FF plenum. Thing is this is using a power FC, has anyone done this yet with a power FC

[GTSBoy]

Wouldn't that be trivial? Surely the PowerFC gives no fark for the TCS stuff.

Thats what im curious to know. As with the power fc the traction control still works

[GTSBoy]

Yuh, but I'd think that the TCS is happy to not care what the ECU is doing, while the (Nissan) ECU seems to care what the TCS is doing.

I'd be very surprised if the PowerFC guys put any care factor for TCS into their Neo ECU.
