Hello Everyone

Been a long time lurker on the forums for a while now and decided it was time to join up!

I have owned a 1997 Stagea 260RS for about 3 years now (actually found it for sale on this board,,,),I live in the ACT and have run into a few of the SAU regulars around the place from time to time.

Keen to meet some people and get some advice on a rebuild that I have going on at the moment.

Thanks!

No pics on the PC at the moment but I see if I can dig some up for you.

I will be posting up a more detailed overview of the build but the gist of the rather long story:

The car had some significant work done to it by the previous owner:

  • GT2860R-5 turbos
  • Walbro intank pump, 2x Bosch 044's and swirlpot in an enclosure in the boot
  • 1000cc injectors and dual entry rail
  • Forged pistons, prepped factory rods, ACL bearings etc
  • EMS8860 ECU and eBoost2 running on E85

The car was in getting the ECU swapped out for something that was a little easier to get tuned and played with in Canberra as the EMS unit had been starting to play up and refuse to run or even connect to a computer.The replacement Adaptronic unit was installed and working flawlessly with a full flex fuel setup when the tuner noticed something wrong with the oil pressure on the final run and then a knock from the big end :(

This resulted in the motor being pulled out and ended up with a handful of toasted bearings and a roughed up crank - looks like I am a another victim of the infamous N1 oil pump...

At the moment I am gathering up the various bits and pieces for an overhaul, seeing that the Stag is a heavy beast I was leaning towards getting a spool 3.4L stroker bottom end.

I found the response to be OK considering the weight of the car and that there is only 2.6L before you start to build boost. The GT2860R-5's are probably about as big as you can go twin wise on a 2.6 and still considered easily drivable, they used to start to boost at about 3300rpm and were well on song by 4200rpm. The only real issue is that the Stag weighs in at around 1700Kg so it is carrying a good 220kg more than an R33 so it does blunt the low down performance a little.

I think that going to a 3.4L bottom end will give it a much more perky manner and mean that I wont have to spin it stupidly hard to make power.

Thanks for replying, it is always interesting to hear actual owners first hand experience. Even more, it does make me appreciate having a 1300+kg 3.0L wagon though :)

It sounds like you are putting a lot of thought in to it and it will be great to see some pics of it one day.
