    Im an indecisive guy, input swap vs boost.

    For the past two months, I've been debating what I should do to give me a little more hp and torque on my e30. I came from a background of 4 mk3 vws, and sold my last one because it simply was no fun to drive!!

    I baught my 88 325is, with bav chip and some fun goodies back in september and have loved my e30 ever since. Back when I owned vws, I would constantly want another totally different car.

    I am slowly working on the exterior, as I daily the car. I am currently an automotive student, I have wrenching experience but nothing to the extent of swaps or FI.

    Im just wondering what you guys would recommend for me, because I am dead stuck on these options. Since its my first time around, I feel that I am underestimating, or "doing it cheaply" and I do not want to have to do this twice.

    M30/50 vs Boosted m20.

    HP: Have ridden in a 350whp evo, reguardless the awd sticks like glue and 350 in an e30 would be a different case, but would like something along those terms.. I am assuming the 300whp range.

    -Reliability (needs to take a punch and still daily driving)
    -Ease of parts/to work on (i havent had experience with timing chains)
    -Fuel economy would be best around the 20mpg range on average

    Ive read a lot of m30 vs m50 threads, and the torque of a m30 seems my thing but I am afraid the mileage would be garbage. My m20 isnt the best at times, but the m30 has another liter of displacement. They also seem hard to find, and trans options are limited.

    As for boosting, I would keep a generic h1c/ holset setup on a b25 with a slight rebuild (bearings, seals, hg, headstuds) but not like a stroker/full rebuild.

    To play with, i have about 2K to start off. I do not have a spare daily (so I couldnt have the car under the knife for longer then a week or so), and should be working pretty often during the summer.

      This is a fairly large problem. A Turbo build/install/tuning is not something you want to rush in a weeks time.

      Sure it could be done and it could be reliable, but unless you have many builds from varying vehicles and a lot of tuning/turboing experience. It WILL be problematic. When tuning is required, Experience is key.


      Your best bet is a straight up N/A Swap bud. At least it's the best bet for now.


      EDIT: Oh, and it doesn't matter what kind of engine. Timing chain>Timing belt.

        yea dude. turbo build in a week is hard to do. stupid little things always go wrong and that makes it more time consuming. Now, a 24v swap! thats what you need.

            I figure an m30 or 50 would be a monster turboed

            Is there any street prices for each swap

            I found a 735i for 1500 but that seems costly for just a swap id still need a trans

            Lastly is there a way I could search by username I tried finding frozen solid on google and couldn't find any of his posts or userpage

              I don't know why people swap m50s for power, it's just not there. m30b35, turbo, or s5x

                I have an m30 e30 and the gas mileage is not as bad as people make it sound like. Some good advice would be to get actual data and not just go off what you heard someone say. It's not that different from an m20 or an m50. And the m30 is easier to work on than an m20.

                Official EPA gas mileage: same car, both manual trans, M50 vs M30. The difference in MPG is small.


                Also keep in mind that in an e30 you will be getting a few more MPG since it's much lighter than an e34.

                As far as power, a boosted m20 will make more power than an all motor m50 or m30. Any one of those engines if boosted will make way more power than the others without boost.

                As far as the 350whp evo, a turbo m20 would probably be able to hang with it. You could hang with a stock evo with the m30 without boost. You shouldn't be trying to compare like this though. With any of these options you will have a handful in the light RWD e30.

                The answer to your question really lies on what's more important to you.
                All 3 engines are reliable NA but a turbo'd engine will of corse be less reliable. There's simply more to go wrong and more stressed parts.
                First decide weither you want to turbo an engine or not then decide on the engine you want.

                  A turbo can be installed in one day, spend the next couple days troubleshooting then get it tuned in a day or 2.

                  I dont see the problem lol

                    2k is nothing, Ive spent more on brakes lawl. Spend that montie on your m20 give her a nice rebuild to last for ever. if you have a little something extra get some bad ass headers, and some decent used lowering springs/shocks. then all new bushing and mounts and your fkin good to go for another 5-10 years broski.


                    In all honesty try to look at the long run, if you don't have enough money it will be a problem. Try to think it through and make a wishlist you'll then see how expensive it really is. Maybe try a loan if that's what you're into.

                      The problem is you're a fucking moron. Go back to 240's where you belong we don't need another 5 toes.

                        Someone woke up on the wrong side of the rag.Its easy, dont freak out there sweetheart.

                        Id like to revise my previous comment. It can be done in a week with plenty of experience under your belt, if its your first time or doing it alone then most definitely dont try it in a week. I agree as stated above that if you only have 2k then invest it elsewhere in the car or save up some more money to do it proper.

                            I understand that 2k wont get a turbo kit I was more or less just stating what I have to start a project not my total budget

                            I was more oor less just looking for input and if anyone knows prices on these swaps that would help a bunch too

                            And I was just comparing the evo cuz its the fastest I've been in and it scared me because before that I drove 110 whp vws but I would like something that can throw you well into your seat
