Monster TD5 Project

But the Quaife 'box is a sequential change, much less likely to miss a shift ;)

It does have straight cut teeth, so might be a touch howly, although it's debatable whether you'd hear it over the rest of the Defender noise :D
Ratios are a little on the high side too.....

I love race dog 'boxes but admit I've never used one on the street :angel:

Really...? You'd fit a 3 cylinder thats about a 50 year old design, which produces 75kw.. revs to 2800, and weighs 450kg!!!!

What an amzing choice for a high output diesel option.. Not.

Walking I feel would be more pleasant.

Quaife also do uprated internals for the r380 if you wanted them:

I would suggest that yes the Td5 can reliably stick 500Nm out all day IF set up correctly, monitored and cared for.. (IE EGT max monitoring, coolant temp monitoring etc etc.)

The issue would be that in standard config even with a VNT it will not be a clean burn to achieve these results, no matter if you have 25psi and some big intercooling it will still smoke. Lots, when trying to map it to 550+Nm.

The trick I would imagine would be to trial 30+ psi, some huge compound turbo setup, matched to big intercooler/s and some serious exhausting.

You may require some deck O rings ,some custom pistons and maybe a different profile injector lobe/ cam lobes to achieve this, but I would hazard a guess and say the bottom end would take it.

After that, many, many mapping hours would be required by someone who is competent at mapping high output diesel engines and has the software etc etc but yes all this would be achievable.

then trans options....I would hesitate to recommend anything less than a full race type of dogbox for a manual, or you could go 6 spd allison auto with a compushift. These can easily take 800Nm....

I await your project with lots of interest:).

i would try and find the rare alloy block factory turboed 3-71...however i would go the isuzu over all other options..

Bad ratios though Pete

Depends Duane, on what final drive you are running and the engine characteristics. A nice long 1st will be a godsend with a lightweight high output vehicle, choose the right ratio high range and launching off the line will be buggy beating to the first turn....:twisted:

Psimpson, thanks, new internals migt be less pain.

Sooo, back on track:
Numbers please gents, this is for the greater good remember ;-)

A TD5 with a torque biased VNT, chip, larger cooler and DGas=??


Thanks in advance, Dave.

throw in a 1.667-1 LT230 high range gear set and some 4.7 diffs and youll have your 18.9-1 first high....and with MD 49% extra low range gear set youll have 54-1.

I didn't even consider low range, after all this engine will be a trans killer in low range if used at full noise:eek:

I would suggest it is being built for high range hard road use/ towing or high speed slogging through sand etc. No need for those stratospheric torque numbers when crawling around with a big reduction case. keep the weight and gear ratios down to achieve good crawling characteristics.
