Thread: Moding isuzu exhaust???

My RRC with the Isuzu up front is 1170kg front and 1130kg rear (empty). I've never seen a vehicle rolling over forwards going downhill, going over backwards going up seems more common.

It's 7.1", but I take your point. Factory figs for a (stock) soft-top V8 Ninety are 1603 kg compared to a mid eighties RR 1790 kg. It would be interesting to see the axle weights of Def90s rig compared to yours.

Currently I have a winged sump, so there is no way of doing either, but does anyone know if there be enough room for both a PTO shaft and the exhaust if a non-winged sump was used?

Alternatively how much firewall hackwork would be required to shoehorn them in?

Cheers

There a bloke on ebay who sells wingless sumps for $125. Look up buy it now in landrover section.

Thanks, they were the ones I was looking at as well. $155 with postage to WA, bloody good price I say! + he's got a few of them.

Just not sure if I need one yet... Routing both the exhaust and the PTO betweeen the chassis rails seems like a big job. Will have to wait til the PTO gets delivered to see how it fits and if I can squeze it past the winged sump.

Wouldn't mind having the extra litre of oil splashing around if I can help it.

IMHO it would be too tight routing the exhaust inwards of the chassis rails, with a PTO fitted, regardless of the sump being wingless. Access to the starter motor is tight at best, and a hot exhaust close by probably is not the best for longevity, not forgetting the PTO uni-joints. To clear all, it would be to low and to vulnerable, even with 33's.

Well after a weekend at Levuka the exhaust was starting to fall off due to it being rusted and the tyres rubbing pretty badly
So it spent the day at our local exhaust man.
In the end we ended up with a 2.5" system all the way through with a nice tight bend around the Chassis/outrigger so now there is about a 1.5" gap in between the tyre and exhaust on full lock

So we are very happy now we can fit 33's on without a prob
in the end it cost us $420 all up
Not bad in my opinion.

I may have missed It but how wide and what offset are the rims on it.?

The tyres are only 33/10.5/15's, the rims arn't very off-setted
