Hi Z heads!

 

The Z31 we have here has a VG30DET (Single turbo from a nissan gloria/Leopard) It hasnt drove for the best part of 2 months, stared it up yesterday on the button, took it for a spin and its boosting at just under .5 of a bar, before this it used to boost 1.1/1.2 bar. Any suggestions? Doesnt feel like a boost leak.

Not sure on 31's mate, maybe some kind of safe mode? The z32 will restrict boost if it detects problems like det etc.

I'm not really sure on the z31 but sounds like safety boost from the ecu

Baring in mind its not the standard engine! Its very similar to the VG30DETT in the Z32

I thought that the Z31 turbo had the VG30DET installed anyway?

 

EDIT: My mistake, aparently it wasn't.

It does have a VG30DET, but not this one? if that makes sense, this engine was only available in japan in the mid to late 90's. Not alot of em around, but alot of parts are interchangable from the Z32

still might be a ECU thing, lemmi go read up on z31's lol

Didn't the Z31 turbo have a VG30ET not VG30DET?

Its not a Z31 engine! lol

ok this might be of some use.

 

 

 

 

 

 

click on thumb nails twice for larger versions (i think lol)

Its not a Z31 engine! lol

 

it will still be plugged into a ECU surely

 

EDIT missed one.

Its not a Z31 engine! lol

 

 

So it's a Gloria VG30DET + Gloria loom + Gloria ECU in a Z31?

Its a Nismo built VG30DET from a Leopard, Impul Racing Ecu with a bigger turbo!

Shorting, possibly causing safety boost to kick in?

could it be a boost leak?

could it be a boost leak?

 

Yeah, it could, might be worth knocking up a boost leak tester, pressurising the system and listen for leaks, at least you can rule that out then, should be fairly easy to do too....

The engine bay seems to be getting rather hot. Alot hotter than usual.

Has the water pump been changed recently? If not i'd change it, the thermostat and coolant.

Just get on the phone to Mike at MJP as he is the man to answer your question as he now has a z31 from Japan and if he don't know he will find out for you

Not as if you do not know him :whistling:

Completely different animal to the Z32

Mikes Z31 has an RB25 in it! He would more than likely know though

Has anyone bought a waterpump from nissan lately?

Tried to pm you but you're not subscribed. Best place for Z31 (even Z31 hybrid) help would be ZClub. Post the question and you might get someone who knows the answer coming on the 21st! 300ZX is, as you're finding out, keen to help but the expertise here is Z32 and Z31 is, as Steve says, completely different animal. Not the same car at all. Good luck.

Yeah we know they are a different car, but a VG30DET (Which is whats in our Z) is extremely similar to a VG30DETT because its from the same era. The Z31 VG30ET is very different.

Good point, Ashwood. But I still think Steve's right - Mike F's your man for that. Plus there's a lot of Nissan hybrid knowledge at the ZClub. There's also a specialist forum http://forums.hybridz.org/
