2.5 + 2.5=2.7

[oze30]

Been told that a 525 eta bottom end plus 325 head will = 2.7.

How does this work as a 2.5 + 2.5 = 2.5 ( excuse the poor maths, but you should be able to work it out!)

If this is the case.. Is it a straight bolt out/bolt in job? ( head and engine mounts trans etc)

The B25 eta engine is a 2.7 (2699cc i think.)

So is it a bolt in bolt out type of instal? What ecu do I need to use? Fuel pump etc??

Its a fairly simple conversion, and a fair few people here are running it!

to save you waiting on responses here I'd advise you to try the "search function" at the top left of the page (just under where it says "members e30's)

It'll bring up plenty of relevant posts that'll help you make up your mind as to the best 2.7 for you

here's an example of the info available...

Just a thought on this subject, is it worth compiling all the information on 2.7 conversions and sticking it in the article section? It would give interested Zoners a comon point of reference? It certainly something that comes up quite often
