Outer Limits 4x4 Board

just wondering if anybody can help new to this forum so g,day everyone
i have a 91 hilux 2.8 turbo diesel 3L engine needing a rebuild we are unsure whether it has the right pistons in it for a turbo engine mine have just the two indentations in the top of the pistons are these right or do they have different pistons just wondering if somebodys just chucked turbo on and making to much compresion pic of piston appreciated and where whould the best place and price be to get rebuild kit from somebody that knows about turbo,s thanks

hey huddo i all so look at geting different piston for my luxs .
everyone one i spoke to said they dont make any ,one bloke said to me you could get a sleve made up and put in the bore and thats about it and a good rebuilder where do you live cheers gavin

I just bolted the turbo on to mine. The engine had been rebuilt 20 thou earlier (not 100% sure) but I made sure I got the injectors done and the pump rebuilt and tuned for it and haven't had any problems about 40 or 50 thou k's later.

When mine dies eventually id like to rebuild it with stronger pistons etc making the engine more suitable for the turbo. I put mine on at 140,000 and its been running 10psi, now has almost 200,000 on it and still runs like a charm (hasn't had an injector service since ive owned it either). If there is a rebuild kit out there with stronger components id be very interested too. Id like to push the boost a bit higher but im waiting to get my pyro before i do any of that... an intercooler would be nice also.

Mine runs 11 psi, and I've heard enough to think that it's no good to run much more than that.
Haven't got a pyro yet, looking at the Thermoguard ones though.
mmm, intercooler, but where to put the stupid thing?

Hey guys don't bother about stronger pistons, they're strong enough.

The 3L (2.8D) is good for 11PSI, I wouldn't go over that as a mate of mine who is a turbo specialist said that is a safe limit on these motors.

I've been running a turbo for around 10 years & haven't had one issue with the motor related to reliability or needing a rebuild. Mine is my business daily driver, so it gets a good work out.

thanks for the info guys did a bit of ringing around and it seem only the imports have stronger components not your run of the mill 2.8 but like you said they seem strong enough found full rebuild kit for $600 should be back in to it by friday thanks again

Top mount would be easiest, but a front mount would be nice, there isnt a lot of room for anything in the lux engine bay Its been on my mind for a while but im unsure what route to go as the pros and cons for both mounting types are relatively the same.

I just got an autometer pyro and oil pressure gauge, $330 delivered to my door from the states, a mate of mine here priced me $384 for the pyro alone and thats his cost price

quick question, ive been told the surf turbo doesnt hook straight up to the 2.8 and that the surf manifold doesnt fit....any help please?

The surf turbo should fit straight up to your 2.8 you just have to take out the studs from teh back to exhaust ports and mount them diagonlly the other way - you should already have the holes in your head to do this..

Do a search for CT20 there is heaps of info on this topic..

just a quick reply, when i did a rebuild on my old lux the standard pistons had the two indentations on it too, so they are most likely standard ones.

Hi guys, Doese anyone know if 320000 ks is to much to put on a turbo.

well i put turbo pistons in mine when i rebuilt the motor, better safe then sorry. I also had to bore mine out cheaper then re-sleaving so mines also 30" over. Im running 10psi, had the pump adjusted to run that boost.

If your rebuilding your motor i feel its better to build it for the turbo, so that way nothing should go wrong. Also remeber to fit a thicker head gasket to lower the compression for the turbo.

Are you saying there is no need do any mods to the exhaust when I fit this up? I've just bought a 3L with the CT20 hooked up. It's coming out of a mod'd surf and was told I might need to take it to a exhaust shop to get the manifold connection changed. Does this mean i just need to change the bolts around and the bolt holes are already there but unused?

X2 it will all fit and bolt up I did not even have to change stud's around when I fitted my CT20 to my 2.8 LN106 the exhaust where it bolts up to the dump pipe may need a little modding though

Be very careful how you go with this, it is not a petrol motor. Diesels need the higher compression to run, if you go too far it will run like shi$ at idle, (may be good on boost but that's not all the time)

There is heaps of info on putting on a surf turbo, it's been done a million times

I fitted a F head gasket wich is the thickest and have had no problems
