yes, but in general people dont. Folk moan about fuel consumption and dont understand why theirs is utterly shite " I never came it/drive it at high revs/...."

Spi engines as std have a horrible torque curve that drops off at 4k ish. this means that revving them doesnt work overly well either. Mines got a nice flat torque curve and the power rises in a straight line to the redline!

i think the best thing to do 1.4 wise would be a c14se with twin carbs, if you wanted to keep the 1.4 that is, they're mechanically simple engines so relatively cheap to tune/fix

my c14se used to be ok in fuel... x14xe was ok too, but even the 20xe returns a decent figure caning up and down motorways 35 mpg ish

want a shot?

last tank was me driving to edinburgh and back. The 60 miles nearest my houe I know well and pulled off in 60 minutes on the dot, in both directions. The rest was in town and short local runs round here. (ie the 12 miles of road Ive known since I was a kid, I know where the potholes are ffs)

hit the reserve at 306miles and took a little under 36l.

I very very much doubt it can do 40mpg being driven like a loon seeing as my 1.2 8v SPi does 35mpg round town being driven very very sensibley, 30mpg with normal driving and 25mpg ragging it :|

when will folk realise spi isnt all that bad!

Mines running a c14se head, 13s manifold ported to match, and adaptor plate to take a c18nz thottle body and a four branch manifold with heated lambda sensor. It does 40 to the gallon being driven like a loon and produces about 90hp. coupled to a cr box in my nova its a lot of fun!

SPi or MPi?

Either way there's not much point, especially if it's the SPi mate :(

so what can i do to improve the performance thats reasonably cheap. ive don nowt to the engine yet part from sparks, oil filter, battery, replacement aire filter element. :thumbs:
