Thread: Monster TD5 Project

JC, great info, thanks.
So for drivability, longevity of engine and drivetrain and dollars, would you recommend TD5 of 4bd1T?

Yep, making huge power too.

Custom crank, Carillo style rods, 2.8 litres, header style exh manifold etc.

I was only reading the old Pirate thread the other night when I couldn't sleep.

[edit]

Firstly, my engine is a very modified TD5,
New crank with 100mm stroke,
New Carrillo type rods 5.5mm shorter than std,
New pistons + 0.020"
New up rated head and mains bolts,
Lead copper bearings on main and big ends.
Ported head,
Garret 2559v variable vane turbo on one off tubular manifold.
Other boring stuff etc etc.
256bhp, 590nm torque. Rolling road proven!

I mentioned the 3-53 because Dave expressed concerns about weight. I would go with a 4BD1T with the wick turned up and a wet intercooler from Frozen boost.

A 3-53T, by the way, in industrial continuous rating is 131 hp at 2500 using N45 injectors. Up it to 3-53TABB with N90 injectors and 3200 rpm and you have a whole different ball game.

Given the hundreds if not thousands of posts on Aulro detailing TD5 problems, there is no way I would consider owning such an unreliable, troublesome, expensive engine, let alone a highly modified one.

Not JC, but I have driven a few TD5s and pumas (only been a passenger in TDV6s), and I am always happy to get back to driving my 4BD1+T. The low down torque of the 4BD1 just makes it so much nicer to drive offroad, or at low speed.

4BD1s manage 500k-1M km between rebuilds, even if not looked after particularly well. TD5s are a good engine, but not quite in that league IMHO (despite the excellent oil filtration).

td5 is certainly smoother and more sympathetic of drivetrain, and lets face it looked after it'll see 500k, but driven hard a 4bd1t will do all this and still see 750k.....

like ben, i get a great feeling driving my 4bd1 110 that i don't get with a td5 engined one, even a chipped one .

it's an isuzu thing i reckon like the difference between a xr250 and an xr600. the 250 will be fine, but the 600 is better and you can never go back

and for the record, i think the td5 is still one of the best diesel engines produced in the eu2/3 era.

Isuzurover, thanks to you as well. I was thanking JC, but was disconnected 3 times and by the time my rply came up, you had posted ;-)
It's all good.
Thanks for the input, all.
Keep the numbers coming for posterity, though.
Dave.

I wish you blokes wouldn't keep talking like this, I had myself convinced a TD5 was in my future although as Steve said the other night, I'll probably persist with the Tdi for years to come.

The damned thing scored a new vacuum pump a few weeks ago, and it's getting a new alternator tomorrow now.....

Thanks again JC.
I was vacilating between 'old-school' no electronics, WVO drinking, chuggin' 4b and a refined light new school.
Cheers.
