Gday Ross,
I'm setting up my td42 with a garret ball bearing GT25 turbo, the exhaust housing on this unit is quite small. At this stage I'm looking at squashing a 3" pipe to pick up the waste gate aswell to create my dump pipe, would this be the best opition to get the flow and heat out of the turbo?. I will be making the backing plate this friday ( to mate up to the exhaust housing) so any help would be great.
Regards
Daniels

people seem to have a lot of questions for me which i dont miny trying to give them the right advice
Re: EXHAUST QUESTIONS ANSWERED BY AN EXHAUST TECH
so is there much difference in a 2.5inch and 3inch exhaust on a Turbo diesel TD42 GQ?
Would there be any power or cooling gains?
what cost for 3inch system.

this turbo you are using may have a small exhaust outlet there is no advantage in squashing a 3" pipe into a smaller outlet
if you can get a plate cut that gives you more internal size for your pipe that would be good
but if not you could use 2.5" for the first 3 " and flare tehe end in a cone shape to take the 3" pipe
when you have a small turbo outlet you do not always have to go large out of the back of it , volume is important but by having a small piece of pipe for a couple of inches you create a vortex efect wich will give you very good gas speed this is just as important
i hope his helps
thanks

depending on your turbo size as in boost
usually you will find an increase in top end power with a 3" system
as far as cooling i dont think it will make a great deal of difference
is your heat problim under bonnet ,water temp or turbo
you need to work this out first to see how to solve it

ps 3" systems are usually about $650
Is there any way of getting more low end torque through a VX Commodore V6 by longer runners or whatever? Not fitted yet, but looking at options when the day arrives (in about 3-5 weeks)
George Carlin, an American Comedian said; "Think of how stupid the average person is, and realise that half of them are stupider than that".
Damkia, one of the best things that people do is fit different rockers. Perfectune or Forced Induction Technologies. FIT's are change over welded up ones at 1.9-1. Sounds wrong but people swear by them. Perfectune are rollers and cheaper but only 1.8-1. Then the usual extractors, cold air intake, bigger throttle body etc.
EXHAUSTFIX, I have a TD42 Patrol non turboed, I am looking at extractors and exhaust system. I know it has been mentioned in other strings but what system do you reccommend? Brand of extractors and type? Size of system 2.5"? Not worried about abit of sound. Has a standard system at the moment. Your help is greatly appreciated.

the best thing i have found for a commodore is good extractors into twin cats and a 2 inch twin system into a single 2.5:rear
this seams to work very well
i hope this helps
every one quotes pace maker extractors for these but i have found on some occations they can be a little big for tb42,spatrolpaul wrote:EXHAUSTFIX, I have a TD42 Patrol non turboed, I am looking at extractors and exhaust system.

i prefer the cheeper brand of wildcat as they have a little more restriction and create better gas speed
if your not to worried about a bit of extra noise then sertainly go 2.5" with a large 11x5x18" strait through muffler in the front and a 5" round resenator in the rear

i have a 1.6 12r in my 4B it has the standard like 1 and 1/2 inch exaust
would i be best to go to a 2 and 1/4 inch
or 2 and 1/2 inch
or 3 inch
cheers
elliot
do not go to big on this as it is only a small engine with limited torque
i would suggest only 2" at max
with a long resenator and a large straight through muffler
rember this
the smaller the engine usually means less h/power less torque and a lot more noise so be carefull
I'm in the same boat as Patrol Paul (and my names Paul...freaky huh!)EXHAUSTFIX wrote:every one quotes pace maker extractors for these but i have found on some occations they can be a little big for tb42,spatrolpaul wrote:EXHAUSTFIX, I have a TD42 Patrol non turboed, I am looking at extractors and exhaust system.

Anyways would 3" be better than 2.5" or is it just spank value? If theres gonna be noise I want a deep note.
Q for EXHAUSTFIX
Hi was wondering if you definetly HAVE to have those flexy braided looking things in the zorst system say on a sd33 diesel in a mq which you are putting extractors with 2.5 system and straight threw muffler on.

Hey ross,
I have a sierra with 1.3, extractors,modded cam and toyota carb.
i have a 2" pipe and straight thru turbo muffler on it. is this the best way to go for allround power/torque benefits.
cheers

Re: EXHAUST QUESTIONS ANSWERED BY AN EXHAUST TECH
I made up tube headers for my B/Block 80 ute years ago out of mild steel tubing and had them HPC hi-temp coated. I have had bad problems with the pipes constantly cracking, im always rewelding and having to pull the pipes off to do it some times. Ive made headers before but being my own 4B had them coated for corrosion resistance mainly. Have heard this to be a problem on exhausts when coated as the pipes run real hot and is a common problem, i also wonder what it does to the steels chemical properties. I am contemplating making a new set but this time in stainless but have had a lot to do with stainless pipe ( Im a maint supv in a steel mill ) and over time the stainless suffers from fatigue cracking. I need the corrosion resistance as the 80ute is a recreational 4B so dosent see regular mon-fri use gets moved around the shed and has the typical mud encrusted moisture absorbing exhaust coating. Mild steel pipes uncoated dont last too long under these conditions so thats why looking at stainless and prepared to go to the expense on materials and full tig weld them but would like to be sure im doing the right thing.EXHAUSTFIX wrote:HI THERE

you only need them in a fwd car where the motor is twisting under torque from front to back or on a big turbo system as the weight and vibration may cause the pipe to brake of the turbo plate
the flexy bits in the exhaust are there to stop the engine torque twisting all the exhaust mounts off ...
i have a supercharged (9psi) TD42 with extractors n 3" with straight through muff and a 5" dawg on the rear in my wagon ... its fawkin loud
i also have a TD42 turbo(T3) hiflowed 15psi and intercooler in my ute ... 3" dump and 3" zaust till just past the cab and straight down dump no muffs ... its also fawking loud ...

the only thing you might be able to try is make your secondry pipes on the extractors about 14" long that may help a bit
cheers for that when i getting quotes for fitting the system (already have extractors but not fitted yet) i had to have one in it and with it in push the price though the roof so i can go now and ask not to have it or find another fitter whos ok with not fitting it inEXHAUSTFIX wrote:no you dont need them with those extractors they support there own weightmuduppig wrote:Q for EXHAUSTFIX

ok no1 use a 10mm plate
no2 use 316 stainless steel
no3 tig weld all joints do not grind back welds
no4 make pipes go in to collector cone in firing order or rotation 1 to 4 in firing order
do no hang the exhaust to ridged make sure you have plenty of movement on the rubber mountd
at the back of the collector cones
make up solid plate mounts and attach to gearbok
if your making your own collector cones put a point inside them
your cracking is due to vibration and sagging under heat
if you do all this you should have no problim
i have a simular setup on the new ford focus world series rally car and that does not brake
thanks for the brain drain
