What else should be upgraded when installing a supercharger

Say I want to install a VF Engineering supercharger kit into my 325ci 2001 Manual (75,000M). What else *should* be upgraded?

I'm getting a wavetrac LSD installed soon.

So far I understand that clutch should be upgraded to performance clutch. The car has sport suspension and 18" M3 wheels. (225 front, 245 rear)

I'd tell you to wait on the clutch unless it's already slipping. When you do decide, PM me, I have something you want.

Agreed.

If you can have someone fab-up a 3" Cat-Back, that would be best. If not, the Magnaflow #16533 is an excellent choice. Consider the BimmerBrakes Equal Length headers, they'll help make better "Mid" range torque.


Good luck,
Rob43

I would like to install a full cat-back Borla system.

The car is a right hand drive so the headers are a problem(steering rack in the way) as all the ones ive found online are for a left hand drive.

Is BimmerBrakes any different or left hand drive only as well?

Borla has a good name, but I'm not personally familiar with their products; I'm sure it will work just fine. But I would compare it to the Mag. #16533, it would be worth 10 minutes of your time to compare both.

Headers: Everything I know of is Left hand drive, so here's what I'd do if I were you. I'd buy someone else's used "stock" exhaust manifolds & hollow/break out the cats, this way you'll have a perfect fitting set of "almost" headers. Then swap them in & KEEP your old ones. This is your best bet, unless you're willing to pay for Custom Built headers.

Did you see the thread on WaveTrac LSD's I wrote ?


Good luck,
Rob43

Don't think that this U.S. Company will ship it for $12 dollars,.....they won't. But it still might be cheaper with extra shipping costs compared to any local seller.


Good luck,

Yeah I've read that. Do you think its still worth buying a subframe reinforcement kit even though its a 325 which should have the cracking problem fixed (unlike his 328)

I wouldn't buy anything until you have it inspected, but DO have someone look at it.

how about a 6spd trans and a higher final drive ratio for your Diff upgrade? I would also do the subframe reinforcement regardless of the current state back there.

I was just comparing the ESS TS1 and VF kits and it looks like with the ESS kit you keep the airbox and things look a bit stealthier under the bonnet, is it true?

Also - Vortech vs Lysholm twin screw. What are the advantages of each?

basically, Lysholm you will have low end torque, from about 2,000 rpm vs Vortech (centrifugal SC) about 5,000 rpm

Just to throw a curve ball, I would suggest the TS2, not because of the added power, but for the extra cooling (assuming daily driver), would be a wise choice for Melbourne summer temperatures.

Has anyone actually had their car overheat with the TS1? Sounds like that would be a faulty design if it can't withstand outside temperatures up to 120+.

The TS2 costs quite a bit more.... Also isn't 8PSI going to wear the engine down quicker? I thought the M54 was built to withstand pressures up to 7PSI without sacrificing reliability.

In a Very real way, the real difference between VF & ESS is the $4K vs $6 to $7K price tag. Both are good pruducts, it's up to you to decide if the extra power is worth the extra expense.


Good luck in your decision,

The cooling system on the ts2 eliminates the heat from the charged air, allowing more boost pressure to be used.

I don't think you will have overheating issues with the ts1, but I would expect performance to drop off significantly during our summer months.
