I had a Honda Integra Type R when I was studying at uni. The car was new and straight from the dealer and it would rev to 9000 rpm without any upgrades as a stock engine. At the time it had 11:1 compression ratio and put out 220hp. It had a 5s close ratio gearbox. A lot of owners in Honda club have only done minor and relatively inexpensive upgrades to achieve 10k or even 11k rpm from the same engine. I don't think this car made it to America though or they might have changed the compression ratio if it did. But we had the JDM spec with bilstein coilovers, large brembo brakes and recaro bucket seats. I think m10 engine is best for bmw enthusiast. It supplements a beautiful car that is credit to German engineering. But it's too expensive to aim for anything over 400hp when considering the m10. The Honda engine and tranny is the ultimate choice when considering ROI compared to M10. Having said so, I think the op started this project on the right track but now heading to universal studios for mad max 5 audition. [emoji1]
