"we were considering a ve head conversion,but after alot of development with the det head we can see no advantage in using a ve head"


your the first person i have heard say that.at 9250rpm do you think you will get piston slap at that rpm with such big pistons.looking forward to seeing what way the head you are taking off looks like after running on e85 will you post pics??running a car on e85 myself

first of all guys im really looking forward to this engine build,as i recon it really is going to be something special,we have found a new love with a 90mm engines and will still continue to further the development of this over a stroker kit and if my new engine is not complete for next year i will be sticking with for next year as i really have not one bad word to say,i still even now think its the ultimate and only way to build a sr20 engine,,,so im looking forward to comparing one to another, with a stroker crank,

thanks for the comments lads,

okay havent got a chance to update this so said id better do it now or it will never be done,,ok first of all i stuck with the 90mm sr22 as it has proved itself over the last 3 years really,,doing over 36 events,,i stripped it to check it and all was in good order and was put back together,,i was delighted with that as i have full thrust in her and willing to push it this year,,the sr24 is still in the works but not just ready yet,,

the first issue we ran into with the start of the year is the withdrawl of maxol's e85 bio ethonal,we a goverment levy put on it,they didnt see it possible to continue stocking it, i didnt want to put the car back onto petrol and with sunoco e85 over 3 euro something rediculas,,that was never an option,but we managed to sort this issue and now have no issue with the supply of bio ethonal so that was one less issue to worry about which to be fair was our main concern,

i rebuilt the 300zx gearbox with all new internals,and now is like a knife through butter,,also fitted a nismo slave cylinder a must really when u upgrade to either a 300zx or r33 box,,so hopefully with a total fresh box i shouldnt have an issue,,

after going to round 1,i hadnt drove the car since fermoy of last season and getting the car running at 11 o clock friday and on the rollers at 2 o clock,i set of for ennis totally unprepared,wrong diff ratio as we hadnt time to change it was a disaster and nerves of something going wrong as we were rushing out if were honoust,,we made the top 32 but got knocked out in top 32,,after thinking i could hear a rattle in the engine which turned out to be cracked clutch pedal vibrating i was glad to get the car home safe(except for shortt cracking the bumper lol) and start preparing for round 2,,

as for the rev limiter,we cannot see an issue,if issues arrise i will cut it down,but it is trial and error,i want to see how far we can push this engine,hopefully will work out,put feel we can push it there,

as for ve head,they are a good way to go,but alot of modifying is needed,and imo is a rich mans conversion(and rich man i am not)mazworx have also designed a new head(de),and they themselves,think the can get the power out of the de head as is,

i will be stripping every part of the engine,and will of coarse post full pics as they come off,im sure you will agree tweek e85 is the way to go,i have just mapped my r33 road car to run on it,and believe it or not im getting better fuel consumption ha
