Makes sense. Appreciate the info 👍

Didn't take ya to be a smart arse. 😎 ...and yeah fair enough. That said, I was more interested in economy numbers than kws- definitely not thinking I own some kind of street beast or that I could turn my N/A into a turbo killer; but all good now anyway. Cheers guys appreciate it 👍 Sounds good, I was under the impression they'd take a whole lot more servicing to keep going & would be a great deal more unreliable.

@camo86T, I was thinking along the lines of realistic improvements (and proof) anyone has got from the mods I was looking at (not just people talking out of their bum), just was interested in some before and after numbers. Either way, cheers guys, was starting to come to the general conclusion that it's not worth it so good to get that confirmed. Will just save my $$$ for a turbo BF later down the track when I can afford one. Off topic question though- how much more maintenance does a turbo require to a standard? I hear you have to service the turbo every X amount of KMs, but I've never owned a turbo car so not sure what this servicing would include.

Thanks man, appreciate that. Got a question with the underdrive kit, does it affect stuff like the aircon, alternator or power steering if it's turning them at a slower rate? It looks like a good upgrade but this cars my daily driver so if I was in a pinch I'd rather have the aircon, fully effective power steering, and fully charged battery than a few extra kw's.

Hey guys, Been looking into some low cost mods for my N/A BF that will improve economy and maybe even give it a few extra KW's. I'll be honest with you all, I don't know a whole lot of stuff about cars but am actively trying to learn so excuse my ignorance. First question I had was that the previous owner of my car had a Redback exhaust installed, I believe it is a full catback exhaust as the pipe is replaced all the way up to the catalytic converter. Am I correct with this deduction? Next question was; after much research it seems like the general consensus is that the best mods for a N/A are ones that improve airflow. Lots of talk about either chopping the front of the airbox out, getting a XR6T or XR8 snorkel, or even replacing the whole thing with a F6 airbox. Other people have also been suggesting a less restrictive air filter (K&N) too. These mods seem pretty cheap but I've been having troubles finding real data on how much they improve economy and/or performance. Another more expensive mod I've heard of is that people are putting Pacemaker 4490 or 4495 headers on the car; are these even worth the price for a N/A engine? I feel like it's not really worth it and is something more for a turbo car... does anyone know effective this is... and would it require a re-tune of the car? So in the end... what do you guys recommend? If I grab a snorkel, F6 airbox (or just cut a hole in mine) and put a K&N filter in there... what kind of economy would I be getting (currently at 10.5L/100KMs) and would I get a noticeable power improvement? Would it be worth putting some headers on considering the car also has a Redback exhaust? ...is it even worth doing these minor mods? Cheers!

Cheers guys. Decided not to buy this specific one as it had a few other issues that I don't have time to fix right now, but still keeping my eye out for a perfect condition one. Will still PM you MBAF, thanks.

Thanks guys. MBAF, appreciate the offer- how much are the kits? How do they compare to the PWR ones as I've been pretty happy with how the PWR cooler has worked on my BA. Also I haven't bought the car yet, just checking it out for now but I'll definitely keep you in mind for when I do actually buy one.

Hi all, currently own a BA XR6 which I have fitted the PWR trans cooler on to avoid milkshakes. I've seen what appears to be a mint condition BF with the ZF box with 220k on the clock which I would consider high enough KM's to warrant a external trans cooler. I'm thinking of picking it up as an upgrade to my BA, so been doing a lot of research on the ZF boxes and need some more advice on the best solution for preventing milkshakes. As I see it I could do three things; First would be replacing the heat exchanger & flushing the coolant every few years to try to avoid a milkshake. Second would be fitting a PWR heat exchanger ($900+, ouch) but from what I've seen, even though it's much higher quality than the crappy Ford ones it could still fail. Third would be getting an actual external oil cooler. This seems like the best option but so many people are saying that it messes with the temps of the box... but I did see in this post here where an apparent ZF tech said that it was fine. I'm leaning towards this solution as it is really the only way to guarantee that it won't milkshake. The car may end up being used to tow stuff so I assume having an external cooler is apparently better for these scenarios too to keep temps reasonable under load. That said, would appreciate any feedback on these options and would like to know what you blokes are doing on your ZF boxes to avoid the milkshakes.
