E46 fi, am I cleared for boost? Compression test inside

Not sure which direction I'm going yet, either supercharged or turbo, but I figure first things first I should check that my high mileage m54b30 is up to the task. It currently has 165k on it.

I was thinking of rebuilding it first but with the following compression numbers I'm asking myself why I would do that.

Results:
1:185
2:187
3:190
4:190
5:185
6:190

Everything else is up to date, either in original great shape or replaced.

What are your thoughts? Rebuild the motor first or just go for it?

Edit: I already know just buying an m3 would be cheaper and arguably better, but I'm looking for a project I can do myself and something unique.

Go for it! It will be unique and always will be something special. No need to build up the motor unless you want more than a specific amount of horses that the kit will provide unless specified.

Nice, Compression test is clear and time to add some boost.

I appreciate the input, it goes along with my thinking as well.

Right now debating between technique tuning stage 1 turbo, aa supercharger stage 1 or aa stage 2. I can't seem to figure out if I want to turbo or sc it, but I do have some time to think and will be asking both companies some specific questions once I have money in hand.

I'm thinking any more than stage 1 is going to be a waste with an open diff anyways so why spend the premium...

The early torque of Nick's turbo setup is hard to beat. Both TT and AA offer great kits, just figure out which powerband better suits your driving style

Any idea estimated 0-60 with these kits? I realize highly variable just looking for a guesstimate that's better than mine. I figure low 5's?

Will definitely be looking at torque curves I don't want to have to beat the snot out of it to smile.

Torque curves will definitely look opposite of each other. Nick's kit with the GT30 (or equivalent) will have peak torque starting around 3-3500. Peak tq/hp on the blower are going to be at redline as it develops boost based on shaft speed aka rev's

E46 fi, am I cleared for boost? Compression test inside

Viral was nice enough to send over the dyno graph today and you are correct, it doesn't start making much torque until higher rpms.

I think in order to be happy with that type of sc id have to at least go with the stage 2 kit.

Now the question is what would I have more fun with, a torquey turbo or high revving sc setup.....

Your very welcome for the information. Supercharger Kits are easier to maintain and install than turbo kits. Either way you will have fun going F/I

Hey Viral,

What makes you say it's easier to maintain then a turbo kit? I like to work with hard data.

I agree on the install...if you're not doing headers, it's definitely easier to install.

Here's another question, what is going to be easier on the car itself?

I know it will mainly correlate to the power being put out, but would a turbo with more low end torque be more likely to blow out other components than a sc with upper end torque/power?

There are a lot less parts in a S/C setup than a turbo. Less **** you break, less **** you need to fix .

Well for starters with our Supercharger Kit the oil for the blower is self-contained so you do not need to tap/or drill in the oil pan for engine oil. Our Supercharger Kit is full bolt on system and can be reverted back to stock. The only maintenance on our Supercharger Kit is a belt which you can pick up at any local nap store and the Rotrex Fluid which needs to be changed out ever 2 years or 50k whichever comes first.

Our Supercharger Kit installation time is rated at 8.0 Hours of Labor. Turbos without a doubt have higher HP & Torque output but be prepared to fork out the $$$ when the wear and tear starts to show. It's bad enough BMW's have more normal breakdowns than most vehicles in the market.
