    ZD30 - Pin fell out of the Grenade

    So I've had this thing for a couple of years after crashing the previous one.



    It needed a head on it when I bought it and since then I've put about 100,000 kms on it.

    It has done a great job towing the racecar and camper trailer around - albeit slow up the hills.

    Had the usual 'NADS' - EGR Block, Dawes Valve, Catch Can plus boost and EGT guages to keep an eye on things.

    Driving to work on Wednesday morning, it lost power and made a shed load of smoke.

    The smoke was the oil being pushed out of the catch can onto the exhaust.

    Managed to limp it home and park it, leaking oil everywhere.

    I'm 99% sure its put a hole in a piston, so game over.

    Leaning towards sticking in an LS1 with the existing auto as the best bang for buck 'fix'

      Why not boosted 4.8l?

        Seems the 4.8 is a bit of a nugget - LS1 has more scope

          Ls1 is still going to be slow as in something that heavy. What about Barra? Boosts and turbo torque will go a long way towards moving it with ease.

              Yrah, but they need rods put in them. 10psi is apparently their limit, although 10psi in a 4.8 would still go well.

                Gen IV 4.8/5.3 has the good rods. Open up ring gaps, chuck a set of head gaskets, springs, cheap cam and try and keep the power under 1500hp on E85.

                    4.8 is far from a nugget. I still vote barra though.

                      My thinking is that LS will be better at low revs (larger capacity) plus it is simpler and I can always add boost as required later.

                      Might do some more research though.

                        LS isn't a low down grunter at all. The Barra is though. Especially with the added load of 3T.
                        Rust is lighter than carbon fibre.

                          I vote barra for the same reason. I think it produces more torque when needed low/mid rpm. LS ainít great down low but the do rev well for a pushrod V8.

                          Barra is also cheap and plentiful.

                              Unless you are planning on boosting the lsjuan it will be a slow thirsty nugget. Iíd run with the Barra or turbo 4.8 litre otherwise wouldnít put less than a blown 6l in it
