vdubhead 51 Posted October 20, 2015 Report Share Posted October 20, 2015 Hiya guys got a question i just picked up a 2.9 bottom end. I was thinking of fitting it to my current head which is a 2.8 aaa obd2 engine. Is there any thing that needs changing on bottom end or is it just bolt them together off you go styley Link to post Share on other sites
daveyboy 897 Posted October 20, 2015 Report Share Posted October 20, 2015 The 2.8 and 2.9 heads are the same mate, they both have the same part number. I think the cams are different tho Link to post Share on other sites

daveyboy 897 Posted October 21, 2015 Report Share Posted October 21, 2015 There's only a 69cc difference between the 2. I thought mine felt a bit more pokey than the 2.8 but that could of been in my mind lol vdubhead 1 Link to post Share on other sites
