power gains!

[greg1.4]

my dad and i are building a 1.4 spi rally car, he is hunting down a set of 40's with inlet manifold etc. But what else can he do to get a fair bit of power out of the wee engine, like cam, 1300 head etc? Can i get bits from other nova engines (cam for example) to get more power?What cheap things would give me power gains? Also if we put the 1300 head and 40's would we need to put a different coil etc?

Thanks

1400mpi head, round port carb inlet.

Sr cam, or even better a 285 fast road cam from the likes of piper or kent

a set of arp rod bolts would be a good investment.

if youre going vcarbs youll have to ditch the spi dizzy and ignition amp and run an sr one.

why not try running it on shell optimax lol.

[greg1.4]

ha ha, might try that, will get power gains straight away!lol

[aswrally]

are you doing stage events in it ??? if so your wasting your time with an 8v
there aint many 8v running in the `1400 class anymore

[Stuart]

also if you go carbs you'll need a 1.4 carb coil/dizzy/ign module......

but as said, 8v's are really losing out now to the 16V boys so your not going to have a competative car...

They don't sell optimax any more :p anyway it wouldn't really net you any gain unless you fettled with the timing. And then you'd probably be best to leave as is and use bog std 95

i ran an 8v for 2 years and couldnt keep up with the top end of the class
dropped a 16v suzuki lump in instant power and up there
better with the 1400 16v if sticking with vauxhall

[greg1.4]

yes i am doing stage rallying. Wanting a quick wee nova like, i have a 2.0 8v sitting there and that was going to go in but i thought that would be too much power. What engine is the best way to go? i just have a 1400 sitting there so thought it would be a good option. Would like to put a 1300 gti swift engine in but what do u have to do/modify? I heard they were rare and expensive but very fast in novas etc.

[aswrally]

2.0 8v forget it never beat a sorted mk2 escort using a warrior / red top etc etc
1400 16v vaux with bike carbs is a good option
or suzuki 16v but like you say getting a good one isnt that easy but you should be rebuilding it regardless they rev well see here for what to do its not that hard or that expensive(in the eyes of motorsport)

Thanks. Dont know what to do now. If i can get a swift engine etc that will be what i am doing. Where do i get all the conversion mouts/spacer it from? Can i have website links etc. Also any pics of nova engine bays with the suzuki engines in?

[greg1.4]

would a 1600 gsi/gte engine be any good for stage rallying/track car?

You'd be a lot better off with a C16XE on throttle bodies.

[greg1.4]

the car is getting painted and caged first before the engine goes in etc so i have a while to decided what engine i am going to put in it?

[Stuart]

what are the classes you get to chose from? (list em all)

few bits for one of them on euro rallye at the moment

[aswrally]

what are the classes you get to chose from? (list em all)
Class A ...upto 1400
Class B ....1401 to 1600
Class C .... 1601 to 2000
class D...... over 2000
all turbo charged engines have to have capacity timesed by 1.7 so for instance a 2L cossie runs in class D but a normally aspirated cossie runs in C

[Adam]

In all classes your going to be better with a 16v engine.
You need quite a few mods to get say a 1400 8v to std 1400 16v power.

[greg1.4]

i am either going for a vauxhall 16v engine or a suzuki swift engine. What would be the cheapest to go for in the vauxhall engines?

[Adam]

1400/1600 16v, can pick them up quite cheap nowadays.
If you get the later ecotec 1400/1600 tho you'll also need to remove the sensor around the ignition barrel for the immboliser system, and you'll need the chip out the ignition key.
