polley 916 Report post Posted September 23, 2011 M20B25 swap is the easiest and is best hp per money spent really. But wont get you 200hp atw without a lot of mods. M50B25 is a bit faster than the M20B25, but will cost you a lot more. Turboing either engine will cost a lot more than $1.5k. Quote Share this post Link to post Share on other sites

Mark 178 Report post Posted September 23, 2011 200hp at the wheels for $1500??? It's possible...but either you'll pop the engine in 5 minutes or slide your 23 year old "stock-standard-apart-from-the engine" car into a tree. Save some $$$, buy a better car.

thorburn 121 Report post Posted September 23, 2011 (edited) Getting a loan to modify a car is a stoopid idea. If you have to pay someone to do all the work you aren't going to get much at all for your dollar. Buy tools(there are enough people on here that will give you advise on how to use them) or buy a different car edit: or Jon Edited September 23, 2011 by bbs Quote Share this post Link to post Share on other sites

_Matt_ 42 Report post Posted September 25, 2011 You could probably swap to a b25 by yourself, just read up on in and purchase the right tools. I'm doing a b34 swap at the moment and all my knowledge has come from books and the net. Quote Share this post Link to post Share on other sites

I picked up a 3.64 medium case diff and 325 axles for $150 (i think that could of been a bargain), up to you if you want to upgrade the diff, but the 320 auto diff is 4.45 if i remember correctly and it just wheels spins right thru 3rd gear and does some thing like 4000 rpm at 100 kph - and then it will eventually sh*t it self and possible leave you stranded some where. So about $2.5K No doubt im missing some things, and up to you on what you want to replace, and depends how much you can do your self. It really all just bolts up, the only thing you need to make is the exhaust, modify the wiring, and I had to make up some brake lines to suit my master cylinder.

No name user 379 Report post Posted October 1, 2011 seriously the best mod you can do is......non do some more over time and do the job right!!! want 200hp easily? no such thing or maybe a 100hp hit of NOS at close to $300 for bottle fill and on an engine unkown? save your money and heart ache take note of whats being told youll be better off in the long run, and have money to maintain it.

dubman 39 Report post Posted October 1, 2011 how attached are you to your car? sell it and buy a m20b25, saves you alot of hassles, and maybe pick up a good deal for a well maintained 325i in the process Quote Share this post Link to post Share on other sites
arrow98 0 Report post Posted October 17, 2011 get a sc14 supercharger and bolt it on. I did that to my otherwise standard M20 and it hauls with about 7lbs boost. Quote Share this post Link to post Share on other sites
