e30 engine conversion

[damodeane]

To make a long story short iv been collecting rb25 parts to do a egine transplant into my e30.its a project that wount be rushed an probably started till the new year.now I still have head loom ecu and few small bits to get.but I've been offered a BMW m30 conversion everything bar the engine mounts.its one that's been done many times so easy get bits etc for.this is a twenty plus year old engine so im wondering is it worth the hassel.i do like the torque and no turbo lag thought.has anyone on here done this conversion on there e30.if so what did you think of it and if you had the chance again would you or should I stick to the original plan with the skyline engine

iv had a good few bmw's iv had 2 e32 735 with the m30 i no in the big 7 you couldnt compare it but i wouldn realy rate them as any good, if was going to put in a bmw engine id go v8, there is an e34 540 manual on done deal breaking there front sumped and every thing would be a handy conversion,

Here it is http://cars.donedeal.ie/for-sale/carparts/4080270 rb25 e30 would be serious tho, was talkin to a lad in mondello with an rb20 e30 and he said it was fairly handy to do

[damodeane]

The only thing putting. It in my head is I have most of the part,I've seen a 26 in one in the net and it looked the business but don't know how it handels

I'd go with a M52/m54 tbh cheap plentiful supply and they wouldn't be a million miles off an RB powerwise or if dollar isn't an issue go with a S5x engine.

M30B35 seems to be ok, but didn't have that wow factor and didn't impress me powerwise. If you want to do something cheap and reliable choose M50B25. If you get a right engine it'll last long and will take a lot of abuse. Swap is cheap and easy. "Will do mondello on 3rd, no bother"
If you have some more $$$ go for M54B30. This engine in e30 shell will do the job. For example, M54B30 powered e30 against e46 M3:


V8 powered e30's are much harder to steer afaik, never drove one myself but few fellas on different forum has them as a drift cars. Big plus for torque from the bottom, but minus for heavy engine.

btw My friend will be selling his ESS Supercharged M54B30 soon.

I would stay away from this car, gearbox is fucked and new one or repair will cost you a lot.

id deff go with the v8 sound mental i was thinking of this conversion in my sierra but funds dont agree at the mo but also curious did any1 few this 540i and also is there any difference in the power between 740i and 540i. if you not planning on using the rb25 running gear would you consider selling
