Cheers

Do it!!
Re: TD42 with a T04E, Any opinions?
just the snail, or manifolds, crossover, pipe work, airbox etc?

maybe their manafild has the same plange as your Turbo you have got

you need more info on the turbo - wheel size, A/R's etc. (I don't know if t04E is specific enough to include that information) - or a fairly good indicator is the power@rpm(@psi if available) of the engine it came off - if the numbers are too big you will find it won't make any difference at the bottom end where you want it, and if the numbers are too small, it will make buckets of boost at very low rpm but will choke the motor at higher rpm.
as a starting point, a TD42 is about 85kW, is 4.2 litres, and spins at about 4000rpm tops. for safe boost, say 9psi without intercooling, you'll make about 125kW, so you want the donor motor to make AT LEAST 125 kW, but NOT MORE than about 1.3x125kW, or around 160kW. bigger than that will take too long to spool (but the top end is likely to be fabulous), smaller will choke. It's only a rough guide, but it's a starting point.
after saying all that, almost ANY turbo on a diesel is much better than no turbo at all. even if it's slightly too small, just keep an eye on the EGTs and learn to shift early. if it's too big, a boost controller can help bring it on song slightly earlier. boost gauge and EGT gauge are ESSENTIAL for this kind of playing around.
slap it on there and have a go!
not too familiar with the TD42 manifold but it might be possible to flip it to use it as a high mount turbo manifold? otherwise if there is space (and there is usually acres of space in a patrol engine bay) you could make a "U" adaptor to run off the bottom of the manifold and back up to the turbo.
a final word of warning, if the turbo has a ceramic turbine wheel, be VERY careful when clocking the exhaust housing if you need to - one touch between housing and wheel and the turbo is junk. no great loss if you got it cheap I spose.
good luck!

it'll be pretty good I think. do you have any idea what motor it is off?skip-unstuck wrote:How does this sound, never had to do any calculations before so no idea on how to do them,

its brand new, advertised for a rb25 or something of the sort, promo say 500hp for a 3ltr vl,
hopefully it will all go well, just need to find a manifold at the right price, what do you think of using a u shape pipe to turn a downward mount manifold into a high mount, will it reduce exhaust flow? i reckon it would work just unsure,
