rasumadu 0 Report post Posted March 31, 2009 (edited) hey guys, kind of a n00b in this bmw world as i havent really had my e30 for all that long but i'm happy to learn...i've started to experience issues with the engine and gearbox inside my 318i so now i'm lookin to do a swap and more notably it's going from auto to manual. the engine i've found is the m20b25 and when i messaged the seller, according to him it apparently comes with 'everything' to do the swap but all i know is that it comes with loom, getrag 250 gearbox, hoses, heavy duty clutch and slave cylinder (stated on his advert) but i'm just wondering if anyone has done this swap before or knows of the other parts that i would need so that i can ask him if its included or he has them available. so apart from the obvious like engine mounts, tranny mounts, pedal box and i think driveshafts, ecu and radiator (i think), anything else you know of? i would just like to make the swap as seamless as possible and any help would be greatly appreciated. thanks.

Mark 178 Report post Posted March 31, 2009 The Getrag will (hopefully) be a 260... that's the box you need. Have you also thought of suspension and brakes etc? With a heavier engine you'll need to upgrade to 6 cylinder shocks and springs and also upgrade the brakes (318's run rear drums) to handle hauling the extra weight to a stop.

Silver Fox 43 Report post Posted March 31, 2009 F/l 318's are mostly disk rear. You need the whole shooting match from the radiator to the driveshaft, plus all the intake side and the exhaust, as well as front suspension. Quote Share this post Link to post Share on other sites

*Glenn* 854 Report post Posted March 31, 2009 You will need to change the diff as well... I have a very good 3.64:1 ratio one here. Its an open diff not LSD $250 Quote Share this post Link to post Share on other sites

rasumadu 0 Report post Posted March 31, 2009 ok so diff to the list...i'm in oz so that might b a bit costly with shipping...can't even express how peeved i am at the cost of parts in oz compared to overseas Quote Share this post Link to post Share on other sites

It will work with out it. you saying i can use the diff in the auto? the suspension part intrigues me as i have dropped in a Euro Tuning sports shock and springs kit into the car less than 3k ago so without having to spend another $900 on suspension would b a plus Quote Share this post Link to post Share on other sites

A 4 cylinder is lighter than the 6 and the front suspension will be lower and will react differently to the 4 Quote Share this post Link to post Share on other sites

rasumadu 0 Report post Posted March 31, 2009 i believe the current diff ratio is 4.10 Quote Share this post Link to post Share on other sites
*Glenn* 854 Report post Posted March 31, 2009 i believe the current diff ratio is 4.10 Youll need at least a 3.64 or taller depending on what your going to use it for Quote Share this post Link to post Share on other sites

*Glenn* 854 Report post Posted April 1, 2009 Use this to work out what ratio you want. Use 6th gear for your final ratio when working it out on a 5 speed http://www.unixnerd.demon.co.uk/revs.html Quote Share this post Link to post Share on other sites
bravo 34 Report post Posted April 1, 2009 Once you have it all in and going, you WILL WANT to change the springs to somethign better suited to the extra weight and you will find you WILL WANT to change the diff ratio to something better suited to the added torque of the 6. 320Guy is right in saying you don't NEED to, and Glenn is right in saying you should. I would wait until it is in and look at your funds. You may want to put aftermarket springs and shocks in and do it once, do it properly, or you may want to save money and use second hand items. Same with the diff, you may want to spring for an LSD, or may only be able to afford to keep what you have or just get a different ratio. Besides, susp. and diff is not hard to change with the motor in - not a lot you'd have to dismantle twice anyway. Check you have disk brakes on the back, and then focus on getting the motor in and going. Also, legally, as you are going from a 4cyl to a 6cyl of greater capacity, you would legally need a LVV cert. You may or may not get away without one at WOF time, and at the very least your insurance company should know. Just food for thought. Quote Share this post Link to post Share on other sites
