I've been told that i may need to lower the compression of my 2.8D hilux before adding a turbo.. is this true?

i've been told to put a thicker seal inbetween the tappet cover and the head, is that enough?

i have everthing else sorted out, just need to no if i have to sort this out before i set the turbo up.

Thanks, HTH

Putting a thicker seal between the tappet cover and head will do Jack to the compression. A thicker shim and head gasket is whats needed to reduce compression. You shouldn't need to lower the compression on a diesel to fit a turbo. Diesels have such a high compression poking another 10psi in there wont hurt.

so its mainly with petrols that its important?
bolt the turbo on and go?? haha..

cheers, HTH

there's lots of reasons not to. just turbo it. keep the boost moderate and keep the EGTs down.

I just put a turbo on my 2.8 and new head i didn't worry about the shim just put new head gasket' i'm running a conservative 8psi which keeps Egt down to below 500deg. Before and after dyno gave it a 37% power increase.. NO MORE CHANGING DOWN ALL THE TIME OR MORE TAKING HILLS IN 2ND I CAN NOW KEEP UP...

Cheers for the comments fella's.
turbo and go sounds good to me.
cheers, HTH

Quick question on the turbo thing. I may be getting another hilux, same model as mine but a turbo diesel, is it worth while swapping the diesel pump over or is it the same as the one on my motor?

And so no one goes just swap motors, the motor in the turbo on has a knock in it where as mine does not

I'm guessing it's an aftermarket turbo conversion as no 2.8 was turbo from factory.

If they are the same engine, then should swap over fine.
The turbo one should have a boost compensator on it to increase fuel as the turbo spools up. May need a vac/boost line for it

If theres nothing wrong with your pump why the change ? You will get a few horses and less black smoke (till the turbo spools up) from the turbo's pump but that's bout it.

They are both 2.4. diesels, as far as I am aware it is a factory turbo but as i said only going on what i was told

Just wasn't sure if the turbo one were different or not or if I needed to use the turbo one

Sorry, my mistake.
Only factory 2.4TD Hiluxes I know of are in Surf's.

Depends which 2.4TD
If it's from a 2.4TD, 2LT (before 8/90 ?), then will be all good just check out any vac lines running to the pump for the compensator.

If it's from a manual 2.4TD, 2LT-E (has EFI on the crossover pipe), then no ..... unless you use the ECU, fit a CAS to the side of the block and change the crank to suit the CAS + some wiring to stop it throwing codes.

Thanks for the Info, I'm pretty sure it isn't the 2LTE as it is an 85 model lux.

So it is worthwhile to swap them and keep my non-turbo one as a spare if it is a 2LT pump

If you have the pump, I would swap it over.

post pictures of both pumps and we can tell whether its worth swapping them or not. its not a small job, special tools are required to get the timing right, you need a puller to get the drive sprocket off etc..

2.8 litre diesels were factory turboed as were 2.4 called 2lte turbo plus ecu 3lte

do a search there out there l noe of one my mate father owns the take off on it is excellent it was bolted to an r series box as well g52 cant handle power from wat l remember it's an r150 box

the 2.8 (3L) was never sold with a factory turbo in any market. whatever your mates dad has, it is not a factory turbo 3L.

I didn't believe you, but still did the search anyway .......

I still don't believe you, please post pics with bore size, crank length and the all important CAS in a factory 2.8 block !!

All this destruction of g52 box's if you drive like a d!ck you will break anything, i've PERSONALLY seen g52s take alot more torque than a 2.8td could dream of and have no problems, also for longer than a few weeks.

I think you talking about a 1kzte, which is a 3.0 diesel not a 3L.

i have a factory turbo and a 2.8 together.

Factory turbo was off 2.4, does that count??

HAHA it sounds like it.
