*INFO* 1.2 8v Tuning Guide

So if i went to my local BMS and got a 1.3 cam for my 1.2 carb it will go straight on and gain me 5bhp [ YO! ]??

How easy is it to change.

Yes


Piss easy if you know how. Not so easy for a novice(cambelt etc etc all has to come off)

Got ma dad for all that.

Sounds good, will get round to it when I get some cash in!

Will post my results on just the cam first, then I'll get round to fitting the GTE stuff and Eurorallye System

good cant wait to see the results

dont forget that the GTE cam wont have the fuel pump lobe for the 1.2 carb pump.

But a 1.3 cam belt will go straightonto a 1.2 with no other mod?

you dont need to change the cam belt novalad, you just have to take it off to change the cam.

i did my 1.2 nova like;- decat, 4-1 manifold, power boost valve, 4.5'' back box, kandn induction kit. corsa sri inlet,loom,cam,gearbox that was the only engine mods and it f'in flew. had over 130mph out it (private land ofcourse) i was beating everything vtr's vts's, cav scoobys everything loved it

[matt_vaughan]

power boost valve? so it was turbo?

some things I'm sure would be beneficial that could be done to optimise the head and get as much power out of a 1.2 are:

Port polishing
Skim the head
Skim the cam carrier (increase cam lift....would be even better if SR cam would be used)
Polish inlet manifold (inside obviously) to help flow

There's also the trick of installing the crank and rods from a 1.3 to basically create a 1.4 1200/1300 hybrid (not sure about this as it's never been done as far as i know...although i'm sure someone has sometime......)...however it isnt a 1.2 then is it.

A Vts would annihalate a 1.2
If you passed one, he wasn't trying, or it wasn't a vts.

not true. i beat a vts round some bends and he flat out refused to beleave it was a 1.2
