Headers & Pullies

[kris d]

Afternoon people [hiya

I was on the other forum (damn) and noticed a couple of posts about upgrading headers and pullies on an SK+ but with no final word on it.
Anyone know if this is possible and what kind of gains would I see?
Making the trip to infinitas on Wednesday and I'm having trouble sleeping (that's your fault Lee :) )
There was also a post about an SK+ 330 slaping a 911C4S of the mark, those American's ay!

RHD headers = custom job (not available from mainstream manufacturers)

Pulleys = timing + air/fuel mixture problem on a S/C kit that has been designed to run off stock pulleys with a specific ratio.

Header if you can get them :cool: :cool: But don't forget kats on an E46 330 are intergrated into the stock headers. So if you get aftermarket free flowing headers, you need new kats as well (they sit aft of the down pipe) You''ll be looking at spending close to £2000. If that's the case, I would just go SK1 ;)

Pulleys, I will avoid. I spoke to Chris about this before and they cannot guarantee that they will work with ASA's S/Cs.

Nick, I think Kris is talking about putting a smaller Pullyies on the SC unit to increase boost.

But have to agree with Nick, if you are looking at talking the hardcore stuff on, go for a SKI, and get custom headers made before you go to ASA, a but late for all this now. I found the company near London that were going to do this for me. However you will also need to buy High Flow Cat's, best place for those is Canada.

Then you are going to have to get a better clutch... the list goes on....

Hi Kris, if you mean the Rogue type pullies then yes they do work fine......but The reason ASA do not fit them is they literally dont fit. When the SK+ is fitted new pullies are added and origional pullies moved so that the lower power steering pulley will not fit. Ive managed to one get them on by moving the pullies myself but its alot of work and requires different belts. It has made quite a difference though.

If you mean smaller pullies on the SC unit then i would wait for the aftercooler kit before upping the boost. Oh and they do run slightly higher than the 0.3bar ;)

As for the headers, Roy can you not get some made up for RHD theres loadsa people after them now.

Cheers ppl
Lee, are the smaller pullies that increase boost hard to fit? Will definately wait for the aftercooler before putting them on and will find out from infinitas any more information on this whilst I'm over there. Will also find out how long till the aftercooler's finished.

By the way, anyone going to the national bmw meet in coventry at the end of april?

[lee330sport]

Not tried to fit smaller SC pullies, i will do when the aftercooler kit comes out, gonna go for around 8psi :D . I did have my charger in bits though a few weeks ago so i dont think it would be too much of a job, but would probably require a software upgrade and maybe injectors.

Clutch and flywheels is the next job. Durgesh have you got your UUC one yet.

Goodluck tommorow Kris, the drive back will be wicked.

[kris d]

Cheers lee
Well looking forward to the drive home :D
8psi from an SK+ :cool: Do you recon that's really possible?
The guy at infinitas said he's gonna show me a prototype of the aftercooler as well so I'll let you know how it goes.

[lee330sport]

PSI all depends on what size pullies go in there. 8psi should be no problem for the Sc. The unit itself snt that much different to the Sk1 kit, apart from the setup.

Get some pics of the aftercooler, still not quite sure how it will work [hmm

[ok . Good luck getting those ponies :D. Dont Foget the 100 ron fuel :D

[Durgesh]

UUC should be here before the end of the week they say...!

As Lee has said its not going to be that easy to increase boost on an SK+, you will need to install the smaller pulley which is fine, but then software, and injectors all of which I know ASA did not do unless things have changed.

Software they might get around by doing what they have done on mine, ie. ASATronic, however the entire fuel pressure system is a extra job to install.

Lee... what's Roy quoting for RHD headers...?? out of interest?

If I had a entire upgraded exahust system, it would just be a matter of a smaller pulley, and I could go to Stage III, and have 370/380 BHP.. how cool would that be!!

My Clutch and Flywheel will be for sale, as soon as they come out of the car. I will sell the lot for £250. ie. Pressure Plate, Clutch and Flywheel.

I havent had a quote off Roy yet, will speak to him though as i really want some new headers, the standard ones look so restrictive.

380bhp your car would fly......literally. :cool:


If your clutch is still in for HIN ill try it out if thats ok. I might have the clutch off you although i was leaning towards the UUC, as ive heard loads of good feedback about it.

[kris d]

Is there such a thing as a silent lightened flywheel?

[Durgesh]

Yeah sure, Lee.. if its still in your welcome to have a go. But I am hoping its out by the end of the week.

Kris, in a word no. :(

However all you have to do, increase the idle by 250rpm, and its all normal again. :cool:

Now I'm interested. I had an E36 M3evo before and the Vanos used to rattle at idle, it killed me! How hard is it to increase the idle?
What are the good points of a lightened flywheel and how hard are they to fit?
Might be interested in yours mate....

[Durgesh]

To increase idle, I hear is very easy, just a little adjustment on the engine....

It basically help's with acceleration... It help the most with the low gears, ie 1st, 2nd and 3rd.

You will notice the difference, also when you blip the throttle you get a faster response, however you have to change gears quick, as the rev's drop faster.
