which transplant?

[iwannae30]

hi guys eventually i want to combine lots of power with good handling in my e30. ive been researching engine transplants but am a bit overwhelmed by the amount of options there is. what do you think the best option is?

any input would be great

[blitz877]

whats the best you can afford??

ford cosworth is the best imo but you will need deep pockets.

Got to agree, a 4 pot up front is the way to go.

So that leaves an M10 or S14.

You can extract good power from both, either N/A or F/I.

id say s50,280ish bhp out of the box with possible fi in future,6pot sound,and relatively cheap thesedays

[iwannae30]

yeah iv seen guys get 400+hp from fully blown m10s although its only an 8 valve can you get 16 valve heads for m10s?

how much do you reckon upgrading an m10 until its beter than an s14 will be? dont fancy looking for an m3 to use it as a donor to be honest

thanks

[maxfield]

An M10 will never be better than an S14, due to it having 8valves.

The blocks are pretty much the same.

Depends how much you want to spend, sky's the limit with an M10.

M30 the thing

[FormerMember]

1600cc M10 with 3,8bar boost => 996hp

Anyways, regarding the swap, it all depends on your budget. S50 is easiest and possibly the cheapest way to get 300hp reliably with very small fuel consumption. But there're tons of choices, just pick the one which suits your budget, skills and needs best.

Sorry to thread hijack, but is a reliable and tractable 250 possible using something from the M50/52 range possible on a budget.
By budget, I mean once you've bought the actual engine ie minimal mods to get into the mid 200's BHP wise.

Look at Danthe's motor, 242bhp iirc.
