I did it - I now drive a 2003 Bora V6 4Motion

[Shane]

Any OEM 17" wheel will fit over the R32 discs,so don't limt your options just yet.

Im all for keeping it OEM though.

[Manaz]

No worries - and that's a rotten filter if it blocks all pics!

I'd like to stay as OEM as possible, and the 17s from the Bora Sport fit over the R32 brakes apparently - that's why I was going with them.

If I have to go for something else, I'll save up and get lightweight 18s I think, unless a set of R32 wheels pop up somewhere.

[Shane]

sorry my bad im in work and pics are blocked by filter! grrr!

If you are hell bent on 17's i would go eith long beaches or santa monica II's

[Manaz]

Ah, OK! Thanks for the explanation.

I've got the 16" brands hatch wheels now (shots are on the second page of this thread).

[Shane]

Never seen those wheels before!

These are brands hatch

these are long beaches (these were actually on my bora when i bought it!)


just some food for thought,throwing s cel means that the "check engine light" would come on,it has been none to happen with soem sport cats etc.

To answer a question you a while back unfortunately i didnt do a before and after dyno run to compare the exhasut-im raging i didnt,the power gains were pretty evident though,dont under estimate a good panel filter either!!

[Manaz]

so the exhaust manifold?

Basically, yeah. Extractors generally replace the stock cast exhaust manifold.

What does "throw a cel" mean anyway?

I hadn't considered the weight of the stock R32 discs. After I wear out the first set of discs, I'll see if a two-piece replacement part is available.

Regarding the 17" wheels, these:

[Shane]

so the exhaust manifold?

[micklosh]

Extractors are exhaust headers (or call them what you will) in which the length of tube on each cylinder is optimised to create the perfect flow in the exhust pipe once they have all come together and head out the back.

[Shane]

The discs are 332mm 2 mm smaller than R32 discs but 2 piece so lighter and less prone to warping through over heating.

The R32 set up was my original choice but the are so heavy i couldnt justify them.

Im not sure if you are aware of this or not but your rear brakes are identical to R32 brakes i.e 256mm vented discs

Im not sure about the exhaust throwing a cell,to be honest im not sure what you mean by extractors? i think we may have another name for those lol

Which 17" alloys are you after the brands hatch ones? or the long beach ones? both were avalaible on the 4mo around these parts and both are readily available on ebay.de or ebay.com for decent money.

[VR6child]

Just like to butt in with a general exhaust question... if you go for extractors and a full exhaust system... do you throw a cel? Due to the wrong back pressure? I may be imagining things here. Sorry for hijack. Oh and I reckon the Bora has a nice sleeper status with the stock exhaust.

[Manaz]

Interesting information on the exhaust. Did you do before/after dyno graphs when you had it fitted, I'm interested in seeing not only the peak gain, but also the difference made throughout the rev-range. I've heard that a bigger exhaust can help up top but reduce torque down low, and I want to be sure I'm doing the right thing if I go that way.

What size are the discs on that setup? I've picked up a set of OEM MkIV R32 brakes (fronts and rears), I'm pretty sure they'll satisfy me for the time being. Gotta find some wheels to fit now, I'm still keen on the 17s that were fitted to the "Sport" version of my car if I can find a set in good condition. The 18s that came on the MkIV R32 would be nice too, but they seem to be even rarer than the 17s from the Bora Sport, and would certainly be more expensive.

[Shane]

Well on a big NA car the exhaust gains can be decent,i have a K&N panel filter and a milltek cat back exhaust fitted and my car dyno'd at 220bhp,i also fitted ECS stage 2v2 front brakes(porsche boxster calipers and massive 2 piece discs) these will fit under any OEM 17" wheel or larger without the need for spacers.

[Manaz]

Thanks Shane.

I thought about exhaust for a bit, but then the car's NA (so far), and I figured the gains wouldn't be that great. I'd be keen to hear if your experience is otherwise.

Suspension and brakes are my first mods (obviously!). I want the car handling and stopping properly before I start increasing power.

[Shane]

Hey welcome to the 2003 V6 4mo club,i can't see the pics as im in work and the are blocked(ill check them out tomorrow)

I have koni coilovers on mine with 18x8 BBS RC's offset et35 i have it sitting pretty low and have exp no rubbing issues.

The 2 essential mods for me were suspension and exhaust,everything else came after that.

Shane.

[Manaz]

I will eventually be going to coilovers - I suspect/hope the Bora Sport 17" alloys will be fine, but if I go for 18s, I'll keep that in mind, thanks!
