    Can I add 100hp with no forced induction?

    Hey guys I was wondering If there was a way squeeze another 100HP out of my 86 325es without having to get a turbo or engine swapping.

                  Hahaha. Good question but there is absolutely no way of that. Like 0% chance. You can probably spend a few thousand bucks and maybe get 20 hp if you're really lucky. Or spend a few thousand bucks and get a cheap turbo kit.

                          Yes it is very possible. A well built 2.9L M20 with ITB's can do it on pump gas.

                          A fully built 2.9L M20 on race gas, ITB's and a crapload of other stuff has done 293whp in race tune, 200hp+ over your B27..

                              If you read mr2peak's post, you'll see it's actually 100% possible. If you don't know, please don't post misleading info.

                                  Yes, stroker M20s are nothing to sneeze at.

                                      Possible but very expensive.

                                              But to answer OP's question... Yes it is possible, but its not going to be cheap.
