V8 diesel conversion on Perentie

[DirtyDog]

I'm thinking about a nice big v8 diesel conversion for my Perentie, I'm thinking if I'm going to do a conversion I might as well do it while I have the body off, stripped and ready for paint... What's everyone's thoughts on which diesel, thinking Toyota or chev but open to others and rest of driveline specs, any advice about what may cause a problem ect... Thanks in advance...

They already have a great diesel. Turbo it and be happy.

Not doubting that for a second but it is a very old truck engine in essence, I'd also like to be able to tow a half decent load... Another reason is simply because I enjoy having a project and building up my own vehicles and I think the Perentie has lots of room for modification, and because a nice big v8 will be a lot more fun.

No really, you have a good engine for it, unless by V8 diesel you mean duramax, then there is pretty much nothing better than the Isuzu, just add 30psi with a variable vanve turbo, intercooler and max out the fuel, it will perform far better than stinky 6.2 and 6.5 chev oilers and return better figures, it will then pull any load you like, easily

I agree...

Although I wouldnt bother with VNT but thats because of personal preference balanced agaisnt budget and driving style. Although If you think youve got the money to source and drop in a v8 diesel.....

There are guys in the states that run those engines under a difference guise at 60PSI.....

you'd also want to do up the front end and make sure the center diff was mickey mouse in the process.

As mentioned stick with the Isuzu but if you really want to stuff it up 8.2 Litre Detroit turbo v8 no electronics unit injectors no rocket ship but will tow your 40 foot trailer full off spare diffs .axles and gear boxes no problems at all and sound nice to

I might be missing something, so correct me if I'm wrong but the 6.6l duramax can make 220kw and 705nm of torque on a safe, reliable almost stock tune. The toyota 1vd-ftv single turbo 150kw and 420nm, the twin turbo which I know used to burn oil for numerous reasons so would have to do some research and see if toyota has fixed this, makes 195kw and 650nm of torque, again both on safe, reliable almost stock tunes. Compared to the 4bd1 turbo making around 90kw and 314nm of torque on a stock engine... They are massive differences... Also I'm not saying the 4bd1 isn't an excellent engine from everything I've read it sounds like an amazing piece of kit, I'm just in a position were I have the time and money and wouldn't mind making something a bit different, if the gains are worth it...

What about something out of a wrecked BMW, Jag or MB Car, (diesel) I imagine they would win hands down on KW per Kg for a start.

Andy availability, cost, reliability, aftermarket parts available, electronics would be a nightmare, information available, and maybe torque also there are lots of land rovers with the 6.6 duramax already in them to get ideas ect from. if I had that sort of money it would get a V10 VW touareg engine

A duramax will cost you 10-15k, my LLY and Allison was 10.5k and they don't fit well in a rover engine bay, but if you are removing the Isuzu, this is the engine to replace it with

a 4BD1 will perform similar to a stock 1VD with good turbo/intercooler and fuel up
