Thats odd, the blue e30 on that auction does not have vents below the windshield.

Superchargers get old fast.

We are upgrading two local customers from superchargers to turbos in the next couple of months.

Skip the appetizer... go straight to a turbo. You will save money that way.

Don't listen to people who say lag is an issue... it's not.

I went with the AA C38 Stage 1 kit. The guys at AA was really helpful and I did the complete installation, by myself in a weekend (I have minimal experience with engine work). My car is an E30 with an S52 motor in it. Everything fit as it should but I had to fabricate my own custom intake as the one from AA was not compatible.

I looked at different Superchargers such as Eurosport and VF Engineering. With VF Engineering and Eurosport, I sent several emails to them, they never responded. I figured if they can't even respond to my emails, they don't take me seriously. When I called them, they talked to me as if I was a joke! AA was the only one that responded immediately and they were very helpful. I highly recommend them. Both VF and Eurosport were a-holes. It seemed like they took me me as a joke and didn't take me seriously. AA on the other hand, took me seriously right from the start and helped me build my car.

The installation was really simple and the instuctions were very straight forward. The car started straight up without any hesitation and has been running smooth ever since!

I think all the heat from a turbo setup in a cramped space spells problems . I think a SC is nice cheap fun . 4kish and it can be done in a day . I love the 210 rwhp but to add 100 more seems like alot of WOW FACTOR !!!

Installation looks very nice. Nitrous too?

Did you dyno the car?

I'm sorry you think that, and I assure you it's not true. The only problem with a turbo setup in an e30 is putting the power down, and that's only a problem with a crappy suspension or tires.

Personally having done LOTS with forced induction setups I'll be going the supercharger route when the time comes. Turbos are great and make tons more power, and no one can argue they aren't more efficient. However, lag eventually does become an issue. I haven't driven a turbo car yet that didn't exhibit some lag. That sort of defeats the purpose of the flat torque curve of the S52.

I haven't dyno'd the car yet as recently I took a corner too fast and banged up the front fenders.... So now it is sitting at a body shop while I contemplate about changing the suspension and getting some wider tires on, but that is another story....

As for the Supercharger vs turbo, AA makes a C38 Level 2 kit which pushes 456 HP....

Sorry for the fender bender.

Thanks for posting your experiences with various suppliers. I have visited each suppliers website many times but haven't yet pulled the trigger.

You may have saved me the frustration you experienced.

Thank you.

I think Eurosport was unresponsive because there is not a snowball's chance in hell their kit fits in an e30.

True, true. The reason I went with AA/Rotrex C38 was because AA told me the twinscrews would not fit as the brake booster would be in the way. But geez, wouldn't a simple reply from Eurosport stating that their twinscrew design wouldn't fit....

I think the frustrating part of talking to Eurosport was ther snobby attitude. They were not helpful from the start as I was trying to understand the concept of Supercharging and the differences between centrifugal and twin screws. Then when I moved on to seeing what modifications would be necessary for putting their product into an E30, they were both giving non-informative and short answers.

AA on the other hand was very excited, and they phoned me directly to explain to me what issues I may run into during the installation such as the oil intercooler and intake piping. And they responded to all my emails within the same day or next day at the latest. They explained to me that the C38 was the way to go, even when I mentioned possibly going turbo. When I finally made my decision to order the kit, it was a no brainer. All of the parts came in a box which was well packaged and all of the parts needed, less the intake pipe was included. The kit bolted up to my S52 without any problems and I sent my ECU to AA. I got the ECU back within a week and the car started without a hitch!

Now if i can only learn how to drive......

OT: eurosport is a joke regardless took me two weeks to get a hold of them on getting me the right part for my m52 swap (ordered the wrong pulley). although in the end they swapped the part for me and didnt charge shipping, still took too long.

id go with the c38 kit.

[ericzz]

Well I bought a kit . I hope to have it installed and road ready before the long winter park
