induction exhaust remap :?:

by **Z3cade** » Thu 13 Oct, 2011 21:52

sell up and buy my 2.8 :wink:

by **swamper** » Thu 13 Oct, 2011 22:17

nowt wrong with the 1.9 :wink:

by **Jamezee** » Thu 13 Oct, 2011 22:19

why not compromise and go for the 2.2

by **stu** » Fri 14 Oct, 2011 12:16

Best tuning mod has got to be a supercharger :twisted:

Not the cheapest though.

Nos is quite a bit cheaper and will give you something extra when you want.

What about driver trainig, tyres, brakes, braces first though?

As said, 1.9 handles really nicely IMHO.

While this is all good advice I don't think changing the car is an option but I would like advice on panel filters against induction kits are induction kit worth the extra money ?

by **jayson f** » Fri 14 Oct, 2011 16:58

No not really it wont make much difference if any, i would just go with an aftermarket panel filter ie K&N or Piper only reason for a induction kit on a 1.9 would be for the noise it makes. A panel filter and a free flowing exhaust and manifold and then a remap might make 10 to 15 bhp (this is just a rough guess) but thats the best part of £1000 to £1500 gone and no great gains for the money! If you want a z3 with bang for bucks it has to be a 2.8 or 3.0 .

by **hornel Z3M** » Fri 14 Oct, 2011 17:53

Or 3.2

by **si-forks** » Fri 14 Oct, 2011 18:09

Thanks for the advice I think I will go with a panel filter the m 44 engine is already 140 bhp only 10 less than the 2 liter engine and it's a much lighter car think I will concentrate on the handle more than the power but I would like to get rid of the standard exhaust cannot seem to find anything for 1.9 just something with a little bit more of a roar would do

by **jayson f** » Fri 14 Oct, 2011 19:02

Lots of companys will make you one now in stainless for good money, try looking on google, or if you have some mechanical knowledge make your own i did it saved me a fortune.

skys the limit with hand made exhausts two pipes or four sir!

by **GazHyde** » Fri 14 Oct, 2011 19:13

I'm just starting tinkering with my 2.0 6cyl. Not looking for big gains, because I know I wont get them. I'm just interested to see what the fuss is all about.

Just waiting for Simota to deliver the correct air box for my induction kit, and then the next stage is a new exhaust... and when funds allow a remap.

Not meaning to hijack the thread, but I think my question is 'on topic'...

Which is better - a hand built stainless steel cat-back system, or would I be better off with a 'sport' backbox from someone like Eisenmann, Supersprint, Powerflow etc.

Contrary to popular 2.8 belief the K&N Induction kit if fitted correctly to the 1.9 makes a huge difference to responsiveness and mid rev range starvation.

Changing the panel filter alone will make no difference as you have not shortened the induction loop, which goes up and over the radiator. with the correct conversion you install a rammed cold air intake straight to the cone filter.

I have done the mod correctly and it makes a huge difference, the other method if you want to use the panel filter is to make the fogged air intake, same as K&N induction mod, but looks stock.

Match this to a stainless exhaust and a remap and you will get 20 - 30 extra BHP and all for £600.

I have spent £245 on the exhaust, £75 on the K&N, I am having a sport CAT and remap shortly for £375

note the 0 - 60 time difference between the 2.8 and 1.9 16v is around 1 second.

Only true route is M Power

Would you say a good place to start would be with a good induction kit

by **Guest** » Sat 15 Oct, 2011 07:56

A good place to start is to fit new spark plugs and leads, then either new injectors (expensive) or have them cleaned, then oil and filter (incl fuel) change.

Then I would do the following:

1) Induction kit (make of your choice), plumb in the cold air pipe correctly, best position is to remove the lower grille blanking plate and install an air scoop, you can then fit a zun sport grille in place of the blanking plug.

2) Free Flow Exhaust, with sport Cat if you can afford

3) Remap, you will be getting more air into the system, the remap will ensure that the fuel air ratio is correct at all rev ranges, improving torque and power. For me power is all about top end performance, I think gains in torque are more important as they affect the responsiveness and 0-60 time so i would ask the remap to concentrate on this. (i drive more on twisty roads and not autobahn)

4) Strut Brace Front (Rear if you can afford)

I am sure if you buy right you can get the above done for £600 -£700, I have a couple of things to do as earlier post and the final cost will be within the above bracket.

After this the cost becomes serious and involves new cam shafts, super chargers etc. the reason it is expensive is because at this point you have to ensure both the bottom end of the engine is robust to take the extra power (lighten, balance, new pistons rings etc) and the Clutch is man enough to transfer the power, a lot fit an M3 clutch which is lighter and stronger. The gear box should be capable though. At this point you will need to look at bigger brakes, and serious suspension mods to keep the rubber on the floor. at this point the cost far out ways the gains, but if you are like me, you do it because you can.

Backs up what i have seen so far

by **pingu** » Sat 15 Oct, 2011 10:48

I think there is no point upgrading for performance before you have optimised what you have got. Hopefully, you have already.

If not, fully service and tune what you have got is a really good start. Not just the engine, but the brakes, suspension and steering as well.

Good quality fuel, oil (engine, gearbox and diff) and fliuds.

You will be surprised at the difference. Especially if the previous owners have skimped on costs.

by **Guest** » Sat 15 Oct, 2011 11:27

Fully agree, and don't forget the injectors, a very much missed piece of equipment when it comes to servicing, and makes a huge difference to get the fuel spray the same as Factory.

Expensive to change for new, but cheaper to have ultrasonic cleaned.

by **msassoon** » Sat 15 Oct, 2011 11:49

A good clean out is a good thing for sure. One thing I have on my 2.8 is an M clutch, but with lightened flywheel. It makes the whole car feel more responsive immediately, as the original dual mass job is REALLY heavy.

There is also a Valeo kit that replaces the dual mass kit to standard, is this the same as the M3 clutch it is about £300?

by **si-forks** » Sun 16 Oct, 2011 13:16

Can i just say what a great forum this is and thanks for all the good advice

by **msassoon** » Sun 16 Oct, 2011 21:37

I bought mine from a member, so not sure of the make, but Valeo tend to be pretty good. The one I have is also lightened, but any M3 kit should do. Make sure you get both flywheel and clutch together as they are designed to match.

by **markrnorton** » Mon 17 Oct, 2011 20:34

The M3 clutch from the 3.0 is the correct one for the M44. This then matches up with the release bearing and clutch arm. You will also need the m3 clutch slave cylinder.

The flywheel Marc has is a chromoly steel one, lightened . I know this because I sold it to him !

by **msassoon** » Tue 18 Oct, 2011 09:59

Cheers Mark! He did indeed. I don't have the M3 slave, but guess that one in the 2.8 was man enough.

Nitrous kit cheapest bang for your £

Its very sad when people are abusive. This is a useful thread and the M44 is a great engine with potential. Its also make the Z3 handle nicely because of its weight distribution/position.

true, you do have to spend a bit of money to get some meaningful power, but that is part of the fun
