well i must be stupid then, is just a bit of fun, just want to see what kinda power i can get out of the engine.

if i wanted amazing power gains i would've kept my 200sx on the road.

are you or have you had it on a rolling road yet

not much diferrence if any, maybe a tiny bit more responsive but nothing to get excited about.

havent put it on the rollers yet, but am kinda tempted to do it before i fit the other parts so i can get a before and after figure.

sorry to be very dim but is the cc the amount that the ports can flow

it would be very interesting to see the differences seems as you are going to be caring out a far amount of work

thats what im thinking, it seems everyone gets shot down when they ask about tunning the little 1.2, so would be good to have some concrete figures for people to refer to instead of 'dont bother its not worth it' from the big block brigade.

the rolling road im using is proper old school and is good with carb vauxhall engines, his rollers are only good for about 200bhp so think i'll be safe to use him throughout this little experiment.

i will get a power run as it stands and another one after he's tuned it up then we'll have some base figures to start from.

any constructive suggestions on this are welcome. :thumb:

to be honest i cant wait lol



i hate all this you could put a xe in it and get more power at the end of the day they could convert it to a space frame chassis and run a twin turbo mid engined 5.0ltr v8 but they don't i hate all the negative comments on the tuning of the smaller engines



i hope it all goes well for you mate any idear when you will be getting this all done

cc is a measurement of area

i'll pop in to the rolling road this week and book the first run, and hopefully the next stage of tunning will be done next month.

volume ;)
