Waste of time. If the injectors are any bigger overfueling the car will not give you any improvements. And as the fords run rich as it is, you'll probably see a decrease in fuel consumption and power.

cheers for that... cause i was a little confused..

yeah, unless you're car is leaning out, then there really is no advantage. And if it is leaning out you'll need to get bigger injectors and tuned. its not as simple as just replacing them.

Hey Guys,

I just got my hands on my dad's XR6 ED with a 5 speed manual and a 3.45diff. I was thinking about doing basic mod's to increase power and torque at the engine by about 15 - 20%. The exhaust in the car is stock, but is a dual 2" after the cat to the rear muffler. Just wondering if I should get extractors, cat and rear muffler, and leave middle of exhaust standard?

From what i've read the exhaust is the first thing to be done, so i was going to do that with an air up grades, ie. K&N air filter, and larger snorkel is an AU or an XH better for my type of car.

Would these mod's get me any where near the 15 - 20% increase i'm looking for, even with a full exhaust system.

I've also hear that Di Filippo make great exhaust but are these mainly for other engine, should i stick with Mandrel Bent.
My budget could probly stretch to $2,500. I'm only talk engine power.

Any help would be greatly appreciated.

for $2,500 you can get a great start on ballsin up your motor. Go for a decent cam (RPD or something) with 2 1/2" Lukey exhaust(all the way) and some pacemaker extractors. You should have plenty of change after that to try some other mods. The main e-series goodies you already have ie. 5 speed and LSD so you have a great base to work on.

a wade cam is only 122 change over(any grind) or go the other site sponsor RPD, pick a grind suited to what you want.

a good clutch ~$400+++

extractors ~$400+

high flow cat, ~150>300

perhaps an EL/AU motor?

could fit all that into your buget if you can do the work.

Yeah probably, won't change the engine. It's already got a better clutch in it then the standard one.

But full exhaust idea is the way to go u guys now confirmed that so thats great.

What about the air system?

stock air intake is fine, unless you're going all out with the engine. With the above mods, you're intake would be fine.

Cheers

Hey guys,

I've got the JMM Dev 5 upgrade in my EL XR6, with JMM headers & zorst, and the JMM ultra-intake ...which is essentially an SS Inductions snorkel going the the standard airbox fitted with a K&N filter, then 3" mandrel bend pipe to the TB.

My question is ...WOULD I BENEFIT FROM A CUSTOM TWIN THROTTLE BODY SET-UP?

It's just that we have a couple of cars here (SVO XR6 to name one) that have a custom twin throttle body set-up ...and everyone seems to rave about how much difference they make in power etc.

How does a twin throttle body improve performance? More importantly ...is it a worthwhile mod option for my car, or am I just going to waste my money for little or no gain?

Forgot to mention, I'm soon going to be shelling out for the BPT / SCT custom flash & dyno tune (Eliminator chip) ...so if the twin throttle body IS worthwhile, should I hold off on the tune until the twin TB is fitted?

Any advice / opinions would be much appreciated!

Cheers.

As you can tell, a lot of what I've done was for "freshening up" the engine. Had already done about 250k kms when I started.
Currently only making 130kw at the wheels.
I'm going to have a look through the forums, try and figure out whether a manual upgrade is worth the trouble, or just go with a shift kit and leave it at that, and try to figure out what gear ratio to go with when I switch the single spinner out for an LSD.

Currently trying to decide whether to keep playing with this engine, or whether to try and find an XR6T engine and attempt a swap.

*edit* Left out the latest - suspension -
Rear - Pedders Sports Rider coil springs,
Front - Pedders Extreme X Cpoil overs, and Big Bore shocks (GSR9180)

Hi all,
Here is my story and we currently have 5 falcons in the family ranging from ED to AU all 6cyl's and they all have very simular power delivery and fuel consuption figures. We are all running different exhust configurations (from standard to 2.5" full flow systems) the only setting that changes between all 5 cars is the type of air pod and/or the restiction required for the air pod (we have finer pod filters, uni pod filters and k & n pod filters)

I put a pod filter on my AU falcon (1999 model) (you need to tune the air flow through the pod to suit the exhaust flow, this takes time and a lot off guess work to get perfect.) almost all air pod filters flow to much air and need to be slightly restricked to get max power and fuel econemy. i also put top spark plugs and top spark plug leads on. I have heaps of down low grunt and have little to no accellerator when at set throttle. i also get great fuel consumption. i average 850km plus per 64 ltrs on the highway setting the cruise at 115km/per hour. you should also check and make sure that the 6 butterflys are set at 3/4 of a turn on from balanced and that the big main butterfly is set at about 2 thou gap (or at operating temp 600-625rpm in drive). also change your thermostat to 82 degree, this is a must and dont listen to anyone that tells you your auto trans wont run properly as they are full of s**t (i was told this by a top ford mechanic).

so to recap:
must do: if you want to help your motor and start seeing improvements
thermostat 82 degrees $20 approx (buy a new thermostat o'ring)

optional changes (does make small gains in better fuel consuption)
good spark plug leads (such as bosch spiral wire) $80
spark plugs (iridium or standard no resistance sparks) $40

optional two (if you have time and patenice)
air pod approx $100
you will see some improvement by leaving and using your standard air box instead of going to a pod filter. my main suggestion if you like this option is to find a way to increase the air flow into the bottom of the air box (ie. bigger cold air intake pickup)

approx outlay exspense of $240.00 if you try all options.

Will getting new spark plugs and leads improve performance at all, or only if the current ones are sub-par? Im guessing it wont make much difference, but after-market ones are neccessary for top performance??
Anyone know about what colour coded bumpers and the twin headlights for an EB are worth?

Recently got a Clarion head unit, getting the car lowered with King Lows next week, followed by a few exterior and perf mods.

hey all i was just poking around my car and i found a cool little spot.
i read somwhere else somthing about pepole drilling holes in there airbox and running pices of hose down to places to get some ram air going. i just noticed on my EBII that rite next to the air box theres a little hole for the indicator wires that leads to a fairly secluded section inside the frount bumper that also looks like it may avoide water from puddles etc i was just wondering if this mite be a good idea to try and get a bit of extra air (as i also read somwhere else about having air runover somthing creates like a cooler pressure or somthing) and what size hose i whould need to use for this to be effective anyone else with the same series know the place im talking about?

cheeres

Well after reading the start of this thread again...is it me or have the prices gone up for extractors?

I called up one of the Distributors in Victoria and they said they sell them for $440 for the Pacemaker 4480s...I remember them being about $410-$420ish. I guess inflation kind of got to it. Is it still a reasonable price for the PH4480?

phong =P~
