Bang For Your Buck Upgrades... N/A

47 posts in this topic
DM

Hey guys,

I have a stock standard BF XR6. Want a little more power and performance.

Was thinking along the lines of;

An underdrive Kit. (10-15rwkw Apparently)

F6 CAI/Snorkell system. (??? Not sure of rwkw increase...)

(Hopefully an exhaust system a little later, and a CAPA Flash tune.)

For the underdrive kit and the F6 snorkell to be purchased - about $250 for the underdrives and $80 for the snorkell. That's $330 all up. Can these mods be done by a novice or would I be better off getting a mechanic to fit them?

Are these mods worth doing? Any other cheap suggestions?

(One last question - my uncle said if I were to get the snorkel, that I would most probably have to change the air flow meter and possibly the plenum - is that right? He said a larger diameter air flow hose from the plenum would also be a good bet.)

Thanks guys,

Dan

I'm also interested to find out how many rwkw's a dead stock BF NA XR6 should have? (Wanted to see how man rwkw's it would have before and after mods...)

About 150? 160? All the talk here is about T's so I thought I'd ask about an NA :tonguepoke:

Cheers,

Dan

Hey mate,

Ebay is your friend, Contact NOS XR on the forums about the underdrives, I'm pretty sure he is selling them for about $200..

Apparently the F6 Intake and XR6T Snorkel are the best bang for your buck mods to do for a N/A, Followed by a K&N Air filter. I havn't got mine yet, So only time will tell.

Go with the above first, Then start looking at a a new Exhaust, You can go all out by and spend $1,500+ on it, Or you can search around for a XR6T/XR8 Catback System, Which should set you back under $150. Combined with a highflow cat, This should give you a nice note. The System is almost a direct fit, Except for the "Y" Pipe that connects to the outlet of the CAT, It needs to change from the "Y" to one pipe, In order to fit the CAT.

After this you should be looking at underdrives, Pacemaker headers, And finally A custom tune.

As for the stock rwkw's for a BF, I'm not sure... If anybody had the stat for a BF & BA, Please post it up :)

Hope it helps,

James

My bro has a BF XR6 and we fitted a XR6T exhaust from the manifold back (we cut the dump pipe and welded it to the manifold) it ended up working a treat as the T CAT is bigger then the N/A's. We got his car dyno'd and it made an impressive 168rwkw, not even tuned yet and still standard intake.

Big dollar saving can be had with fitting a second hand Turbo exhaust.

Make your headers 4495 Pacemakers, theres a guy in Vic that sells pacemakers on ebay, if he not running an add for the 4495's email him. I got my old headers from him and saved about $200.

I would defiantly start with the exhaust, but when you're looking for one remember you can't change the CAT because of the second o2 sensor, if you do the car will go into limp mode.... however you can have this edited out (along with your warranty).

I went for the Pacemaker 4490 (for the low down torque) and an 2.5 mandrel bent catback system done by XForce. set me back about a $1k all up

then when I got my edit the first dyno result (with only the exhaust) it got 170kw. After the tune and air filter I got 180kw

(a BA N/A (auto) went on the dyno after mine with just a exhaust and air K&N filter and pulled about 165Kw after the edit)

As for you intake just wack the snorkel on there. there is no flow meter...that I know of... the ECU will adapt to the extra air and theres no need to change the plenum.

Exhaust in my opinion should be the first mod.

the only other thing I can think of is Cams

silly question....if you put different cams in does that make your engine a open motor (opposed to being unopened)

Heres the run down

4495 header will net you anything from 15 to 20 Kw

A performance CAT is a must.

2 1/2 inch exhaust is a must.

Air filters are almost all the same.

Under drive 9 rwkw 12 to 13 Kw at the fly.

Edit with custom Tune will get you 14 to 15 rwkw about 20 at the fly.

Crow cams, bigger job but the stage 2 will get you about another 10 to 15 rwkw after tuning.

Over sive throttle bodies, looks the goods but that's all they do for you.

High stall, will drop .2 off you 1/4 but reduce you dyno numbers (if your into that)

4.11 diff gears will make for a pig at the pump but drop you another .3 to .4 off you 1/4 time.

All this isn't that much, and when its all said and done you'll run in the 13 sec club all day long.

Expect $5000 to do it all, but at the end of the day you'll have a 13 sec car, lower fuel bills than a XR6 turbo and more power than an XR8.

There a number of guy sporting this type of set up on another Ford Forum and they love the challange of building a vehicle that's almost unsupported by most tuners.

Theres more equipment on its way but who knows when it'll get here.

Hope that helps.

So a good way to go would be;

Performance CAT

Exhaust system (Do I want a ful system or a cat-back??)

Headers/Extractors (are the 4495's classed as extractors or headers??)

Custom Tune

F6 Snorkel - CAI

Underdrive kit (NOS XR - are you selling any?)

For these mods - how much in $$$ for the parts and labour roughly and how many rwkw roughly?

For your list there about $3000 to $3250 including fitting.

Underdrive kit (NOS XR - are you selling any?)

take a good look for underdrives on ebay mate.

The high stall and diff would add a bit under $2000 fitted.

I've just fitted a custom 3" intake pipe and pod filter behind the headlight.

and a XR6T Exhaust from the cat back, and I must say it runs alot better

and sound better. much more puncher threw out the revss.

but you can tell it needs a good custom tune to get most of all the

gains out of those to small mods.

ebxample - Is that whats currently in my XR6 PLUS the secondary lower snorkel?

Where are you located mate and how old is it all? Good condition?

Thanks for the responses guys - I really appreciate it :)

I have seen 20% BA underdrives on ebay - Will these fit my BF MKI??? Also looked for those 4495's but there are none at the moment.

And in the exhaust department - do I want a 'secondhand Cat-back turbo' exhaust?

Cheers,

Dan

The guy that sells the 4495 never has them listed, I don't know why, you need to email around a bit and find the guys, all I remember is his price was $200 lower than I could get in Sydney and he was from Vic.

The Under drive for the Falcon 6 cyl fit all BA-BF-FG falcons.

Hey guys,

Thanks for the help :)

Found an underdrive kit for $215 without a serpentine belt though...Anyone know how much these belts cost?

Hopefully getting a BA Typhoon Exhuast system.

Still searching for the headers.

Hopefully sorted out the snorkel.

Still after a performance cat

Flash tune will come later...

CHEERS EVERYONE!

any good exhaust shop that sells your headers should sell you a hi flow cat .... but remember you can't change the cat without doing the tune! you'll have to get your tuner to do do the change over so they can edit out the euro4 emmision settings. otherwise you'll get halfway down the road from the exhaust shop and wonder why the engine light is on and your car is acting doughy

The Exhausts for XR6t and the F6 are the same, so make sure you dont pay any extra just because its off a phoon.

Thanks Russ,

If I just change the Exhaust for the moment, I can keep the same cat until I get it changed, right?

The bottom half of box is different with the lower intake and the side snorkel off the turbos are bigger than your xr6 one. I am in Frankston,Melbourne.

no it wont.... ford work upon this principle, if your mod breaks something or causes a malfunction then they will not cover it under warranty

not sure if this helps anyone, but ive just got a quote from my local exhaust place ( exhaust innovations in brisbane ) ive got a ba xr6, full exhaust system inc. PH 4490's. 575 fitted, hi flo cat with mandrel bent steel piece attached. and Redback twin outlet 2 1/2 inch cat back exhaust, all fitted for $1490. I was reccomended by brian (owner) to avoid xforce as its cheap and nasty, redback is australian manufactured so you know your getting quallity.

if anyone is in the brisbane area looking for someone to do their exhaust work I highly reccomend him as he did my prelude before I got my xr6, that was a full custom job and the welds were perfect.

so yeh, for a High quallity full exhaust system ( excluding comp headers due to I prefer to keep my bottom end grunt ) $1490 fitted and installed sounding sweet.

Ugh....wrong.

Explain why I fitted a 2.5in" high flow cat to my BA Mk1 XR6...and didn't get a tune or anything like that. Never once seen my engine light come on, and it was far from doughy. o2 sensor is located before the cat on the std headers anyways. Hmmm.

As for bang for your buck mods...Get an F6 lower intake, K&N panel filter and an XR6 upper snorkel. Won't really give you any rwkw, but you'll get better throttle response and a nice induction roar. All up...well for me...It was about $150ish. If you wanna go further, build some custom piping from the airbox to the TB.

Exhaust is the next thing. Good set of headers, 2.5in" catback and a high flow cat. Should pick up a few rwkw there.

Underdrives next. Good luck finding someone to put it on though. You need a special harmonic balancer removal tool...escpecially built for the Barra motors. Think it's like $180ish too. You could always use a normal tool and breaker bar to the ground and then crank the motor....not reccommended, but it works. Also, when doing the underdrives, replace the timing case cover seal (I think that's what it is). That's about $40ish.

Umm...BPT thermostat is a good investment. Doesn't open fully until 104 degrees or something, std opens way earlier. They are about $40. Once again, no rwkw increase.

Pretty much after that you're looking at decent coin....$600ish for a flash box, plus custom tunes. Scrape in for under 1g there. Cams and valve springs, once again...600 for cams, 450ish for valve springs, plus the money for another custom tune...Over 1500 there. Then you can look into doing headwork...which I don't think anyone with an N/A BA/BF has really explored....Ummm if you are after high end torque, you can look at the option of a turbo intake plenum, not much rwkw increase for the dollar though....Would be a good $2000 all up for that I'd imagine. You could get a custom twin throttle body setup made....Once again, big money for small gains...Also I hear rumours of a TB spacer being made for the N/A 6's...which should see some good gains. Stall converters, diff gears....LSD....manual conversion....All these things spring to mind. But remember it's not how much power you have, it's how well you get that power to the tarmac.

So in saying all that, there is definatly potential for a 200rwkw + N/A 6...especially with a BF as they had the barra 190 motor...dual knock sensors and dual cam timing. But, you'll need to spend some big coin to get there. But that's the price of being different.

Hope this helps. Cheers
