Quick question. What jets should i use in my 32/34? 1.3 jets?
Ill be using a 1.4 SR cam and ingnition.
What on, a 1200?
1.3 jets would be a good starting point aye
Should at least run well enough to drive
Clues in the thread lolQuote:

Oh yeah lol lol
It will probably run fine on 1400 jets too(down on power/mpg obviously like), might need a play about with the idle mix/speed.
I might try and xource some 1300 ones methinks.Quote:

Can anyone tell me are all the 1300 cams the same, or are the SR ones different? I see cams advertised for sale and they all say 'all 1300's' ??
Thanks

The only difference would be Irmscher cams in a sport.
Thats Novas though, not sure if any other Vauxhall engines had different cams mind.
even then tho jack the enem cam was an option most didnt go for
Just aquired a 1.3 engine, how tempting to slam the crank and rods in the 1.2.
Now me and my dad rekon the result would be a relatively lazy engine due to the long stroke, but I've been told they rev nicely.
What cam have you got in your 1200? Have you skimmed the head at all?
I'm doin a sport replica & thought of taking out the 1200 & put in a 1300 but after reading about your 91bhp 1200 I don't think ill bother.
will a 1.6 gte cam fit into a standard 1.2 spi engine? and run fine? as i am lookingg to do this
Yes
So does that mean i could fit a GTE cam pulley? would this make any difference? can you get lightened ones of these?
Gte cam pully is same as a 1.2i one
so this gte cam fits the spi engine and not the ccarb engine am i right
Isnt there an article for tuning SPI engines?
Edit Yes!

Incase anyone want som info on the Cams...
Lift
Inlet Exhaust
12ST - 5.1mm 5.5mm
12NV 4.7mm 5.1mm
13S/SB 6.0mm 6.0mm
So you can see that just by changing cam to 1300 Cam would give some half decent gains, even moreso on a later 12NV model engine.
The Kent Cams
Kent AST1 Sports 6.24mm 270 degrees
Kent AST11 Sports 6.09mm
Kent AST18 SuperSports R 7.75mm 304 degrees
Kent AST19 Race Spec 7.46mm 313 degrees
Kent AST17 Supersports 6.95mm 284 degrees
More info is available on the Kent Cams site
Kent cams states that the AST1 give 10bhp increase on 1300 engine ;)
Just bought a kent high lift cam and pulley for my 1.2carb on ebay for £46 :)
Bargain, I'll check the lift on the various kent cams to add to above list
I know i couldn't believe i had won it as i was at work when it ended and i thought i was going to be out bid at the last minute as usual! lol
Im not sure if I should get twin wbers or just a 32/34 weber carb on a 1.3mani??i can get an irmscher inlet mani for the twin webers for 50euro off a guy over here lik!
Twin 40s. I posted a "guide" for jets for twin 40s including a 1200 engine in the articles section. Check that out.
Or do what I'm doing on the High Comp 1.4....Bike carbs!
I have no license, My car runs fine and no its not road worthy, It was at my friends dads garage i had my nova there for the night so i was mucking around in it with my mate in his zetec s and yes its private property.Quote:

Eh i have a bit of a problem becase i don't actually know where the jets are in the engine or what they look like lol
I would **** up the bike carbs and there is know one ova here who would be able to set them up properly for me!
Do twin 40s then, its relatively easy conversion and been done countless times.
please note.... this is NOT a chit chat section of the forum. Its an articles one.
I shall read through later and remove posts/people if need be!
would any of this work on a 1.4 8v in a corsa b ?
http://www.pngclub.com/forum/showthread.php?t=93430 only had to go back a few pages in the articles.
how much do you recon 1300 con rods would cost? i have a crank but need the con rods to make it a 1400
Im looking at a set of R6 bike carbs, will these work on my 89 mk1 1200 or will i get a better gain from twin 40s or a webber. also if i fit a 1.3 crank and conrods will it be safe to skim the engine and roughly how much by.
just another point to tuning a 1.2, is it not worth porting and polishing the head and inlet manifold, fairly cheep and easy to do!
Probably. I'm going for higher engine carbs (CBR900) as I want higher end power.
As far as I've read, smaller carbs give better low down torque, larger carbs produce higher end power.
Depends what you're after really. Those R6 carbs will need the jets drilling out, or replacing, weber ones can be used.
IIRC a good starting point for 1200/1300 engines is about 135-140 jets, then trial and error is the aim of the game, unless you have enough dollar for a wide band lambda sensor.
I'm currently porting and polishing a head for a college portfolio (Motorsports) so I'll be putting up a kind of "How I did it..." rather than a guide, as some would cringe at the stuff I've set to on this head lol
from all this work what is the power gain?
