Dinan working on 628hp V10 for M3
 

We have heard about that in M5 and M6 but the guys at Dinan have some crazy ideas. 628hp V10 in M3 combined with reducing the weight of the car = Sick!!!

Sounds great until Dinan shows you the invoice...I'm thinking $20k plus installation

LeMans: naturally aspirated, turbo, or super?

20k isn't even going to be close, it costs more than that to have the 5.0L v10 bored to 5.7L with throttle bodies, and exhaust + you have to buy a v10, it's going to be in the neighborhood of 50k

sorry I retract that, the S3 package for a m5 is 59k, so it's going to be more like 100 for the m3

I didn't even factor in the cost for the V10...I was talking about the Dinan parts, but you're right its a costly mod...for that kinda loot just buy a P car and call it a day.
