thanks guys for your reply,

Yeh turbo'ing my current engine my be option but i rather engine conversion.

i cant just put a normal rb25det in the engine bay coz normal rb25det is rear wheel drive where as mine is 4wd. it will just cost more.

Hmmmz, im just lost...:|

you can also use a AWD RB25DET engine out of a laurel, gloria or cedric... not just a stagea.

but yes, AWD RB25DET's never came out in a Skyline, and of the cars that it did feature in, very very few of them are manuals. So you gotta be careful with your diff ratios, or risk ATTESA having a hissy fit.

The engine (Stagea RB25DET) for my conversion cost me $3800, 18 months ago. It came complete with an auto box, which I basically discarded (since my 'line is manual).

There is no need to fret about the differences in diffs causing havoc with ATTESSA. It is relatively easy to swap the (front) diff out of your current setup into the Stagea engine. Or fit a Stagea rear diff at the same time. If yours is already a manual, then it's also relatively easy to transfer the flywheel / clutch onto the RB25DET - only requires a new spigot bearing.

RB20DET would be a waste of time. That's why I put the 25 in my 'line in the first place (R32 GTS4) - would be even worse trying to haul around a lard-arse R33 with a gutless RB20DET (but, if you want one...)

    • I thought it could be an issue because the standard plate was flexing when stressed. Maybe the original gear set will hold a bit better without flex? Last time on the dyno it made around 670nm at the hubs. Now it have bigger turbo and better intake but have not been on a dyno yet. The car is being used from family trips to drag race events. So the shifts can be a little violent. It is grinding if I shift to fast so was thinking I should overhaul it soon.
    • From the factory on RB26s there's a fitting on the intake manifold collector/"plenum" that provides pre-throttle boost signal. That's how they did it back in the day, I figure it's fine to replicate it.
    • I would be surprised if that wasn't the issue. It's probably telling you, that even if you remove the plastic liner, you may have some other clearance issues that may occur too in some scenarios. IE, tyre to guard. It looks like someone has already rolled the lip, but you may still have issues in the future IE, turning and hitting a bump etc. The fact it changes how bad it makes the noise when you are going backward vs forward is highly indicative that it's the tyre rubbing. They do make a terrible sound, even if you're only pushing a project car that has a liner hanging down on a tyre!   Has the car been lowered? If it has been, what is the measurement from the centre of the wheel hub to the lip of the guard straight up?

    • Mark's a bit smarter than people give him credit... He'd convince the person that is to become dead, to drive him to the forest first. That way his car has no evidence in it, and he's free to dispose of their vehicle permanently how he sees fit too...
