ive got a bone stock non intercooled kzn185 done 230k.

im to soon be towing a trailer around 1800kg quite often, so need to get some more juice from this beast.

from what ive researched, can someone answer these questions

--- what intercooler can i install that will not require a body lift, apart from the standard setup from a intercooled kzn185.


--- i am installing a 2.5" mandrel bent exhaust from the turbo. im fairly sure by installing the pyro egt gauge in the down pipe 10cm from the turbo will still give accurate results, except at a slightly lower temp level?


--- by tightening the screw on the fuel pump, its giving it more diesel, so will this in turn more gas, or the same, as by giving it more diesel, yields greater power so less acceleration needs to be used?.. and if that theory is correct, this means it will have higher max power?


--- am i right in saying that by using the egt gauge, i can wind up the boost to say up to 15psi so long as the egt's stay at an acceptable level, as well as give more fuel if need be? and that this will be safe for long towing periods providing the egt's are safe.. i know on petrols the higher the boost we would wind the timing back. do we have problems with pre detonation on diesels?


--- lastly by doing the above, cleaning out inlet manifold, ditching egr. ditching the throttle body, intercooler, exhaust, boost, maybe fuel if doesnt worsen economy alot, , how much power could i obtain extra,



hope thats understandable, just needing to be sure i tackle it the right way,


thanks

I also had a thought that by just changing the downpipe to a 2.5inch jobbie and center muffler to free flow the standard 2 1/4 inch tube piping could provide for some good gain. Im trying to do this on as much of a budget as possible

cant answer but you should be able to fit something in there

Pyro probe really needs to be installed pre turbo. i.e in the actual manifold before the turbo


--- by tightening the screw on the fuel pump, its giving it more diesel, so will this in turn more gas, or the same, as by giving it more diesel, yields greater power so less acceleration needs to be used?.. and if that theory is correct, this means it will have higher max power? would generally be correct, but 1kz-te is electronically controlled so the only real way to wind up fuel is with a chip or by installing a non electronic pump

yes but you cant because of the computer

I answered what i could for ya

thanks

my logic behind thinking the egt gauge put in the downpipe is that i will install the cars exhaust first, get all the readings from the egt tempretures, as this should be safe levels seeing as its basically still a standard engine, then start modifying keeping in mind the original tempretures with just the exhaust added... wouldnt that seem logical?



ok so effectively without a chip tuning the diesel pump wouldnt work so a fuel increase is off the list.. it seems that raises the egt anyway.



in terms of the computer sitting on a solid 14psi, the car should still provide enough fuel to keep the fuel mixture correct?
