Thread: V8 diesel conversion on Perentie

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...

In red.

they're not.

the 4bd1 worked up is more than capable of outputing safely and reliably far more power than the rest of the driveline, vehicle and brakes are reasonably capable of dealing with. (hell if you're wanting to spend the money on it you can do that with a 300tdi)

remember 2 basic basic guide lines for turbo diesels. (and this generally assumes similar technology levels)

a given size diesel engine running at 1ATM of boost can make as much power as a N/A engine twice the size

an N/A engine can never be as efficient as a an engine half the size running 1 atm boost.



Every single big diesel convestion I've seen lumped into a landy usually fall fowl of one of 3 problems

1. the rest of the landy wasnt made for it and it screws up some other characteristic
2. The engine suffers from heat related issues
3. it ALWAYS costs more than you think....

Im going through that process now and all Im doing is dropping a 3.9l izusu and matching lt95 into a series III

IMHO...

your best efforts are spent on modding your existing block to the 4bd1-t spec and then sorting the turbo out properly.
.

dont forget to uprate the clutch on the way.

Another option Steyr
Diesel Engine 6 cylinder (3200 cm³) M16 - Steyr Motors

My ex neighbor sells them, mainly as a marine replacement for 351's , and priced very competitively from memory. Being aimed at A.H the electronics are independent of the implant vehicle/vessel .
But not a V8

Sorry I should have mentioned I don't plan on keeping any of the existing running gear, I'm not sure what I'm going to use yet still at the very beginning of planning stages, if I decide to do it. Some ideas so far and this needs alot more research is buying a wrecked late model range rover from the UK/Europe and using all of the running gear from this. Still exploring other options if anyone has any ideas...

I'm aware of costs and work involved have been building race cars on and off for almost 10 years...

well thats a totally different kettle of fish.

If you want real power might I suggest the turbod version of the detroit (or GM) 8V92

I can also reccomend something in the range of jet turbine engines.

Well why would you have bought a Perenti then - you could do what you wanted with any old 110 and the start vehicle would have been a lot cheaper.

I'm not aware of many two door, tray back, sft-top 110's in absolute mint condition with 10,000km's on them that I could pick up for $7,000... Also I'm guessing I can sell engine for $2,500 it literally looks brand new, then sell gearbox for around $2,000 considering a rebuild kit cost $1600 and I've almost got my money back for Perentie.
