Posted 05/10/13 03:03 AM Share Posted 05/10/13 03:03 AM Gday guys I have a 2007 bf mk2 xr6 turbo and ive grown tired of 350rwkw and looking to go for the 400 and run a high 10. So I still wanted around a 350 rwkw street tune and full united e85 track tune but want to make sure my car will handle it. I have all the supporting mods but I would be changing the surge tank with 044 pump to a process west twin DW300 system im thinking. So I have been looking for info and cant seem to find a definite answer. With the N/A bottom ends are they same as a xr6t just the rods and pistons ect are different. Would I be able to build a n/a bottom end and stick my head onto it? What else would I need to do other then rods, pistons and a head stud kit?What about fg f6 bottom ends? I read somewhere that there not the best options as compression ratios are different but are still good for about 440rwkw with a bf head? If that's not the case then I have a mate who works at ford and can get me a fg f6 bottom end for close to 2 grand and would be an easy option. How much power could my engine hold with a full tank of e85? Its just clocked 107 thousand kays but is only driven for a week out of 3 because I work away. Ill be taking the plazmaman kit off and putting a Nizpro kit on as well. Thanks for the help guys. Link to comment Share on other sites More sharing options...

It should be able to hold 450rwkw with E85 and the right supporting mods. 1 Link to comment Share on other sites More sharing options...

I thought 400 would of been pushing it haha. Mods will be a nizpro cooler kit, id 1000's full exhaust, twin fuel pump set up and turbo mods. Anything else I should get? Ill be chucking a head stud kit in and some valve springs as I still have the factory ones! Haven't failed me yet! * touch wood * Link to comment Share on other sites More sharing options...

I make 370rwkw with nizzy cooler, 5" cat, ID's and surge. E85 is a great power adder. Link to comment Share on other sites More sharing options...

I thought I was getting Into built motor territory. So even at 107xxx Kay's it should handle it fine? I've had it since 60 thousand and serviced every 5-7000 Kay's.

Posted 07/10/13 02:08 AM Author Share Posted 07/10/13 02:08 AM Well this is awesome and unexpected haha. Just about finished paying for my wedding then the fun can begin. Just need to get my hands on the new surge tank, plenum and then im good to go!What sort of fuel lines and fuel rail will I need? Will a process west or plazmaman fuel rail do the job? Or is it a little more complicated? Also just curious though with my question about the N/A bottom ends? Are the bottom ends the same, size wise? Just the obvious differences with weaker rods ect?

I think your bf rods will be fine on e85 ,but if your going to crack it open ^^^ Link to comment Share on other sites More sharing options...
