Or try this
Bet thats a bugger to steer lol.
Seriously though getting back on topic and leaving the buy a 1.4L answers out.
Re-map will give you another 6-7bhp. GSR induction kit will give you quite a bit more torque. Just be careful of the diff going boom lol.
GSR do a remap for £199. Induction kit is £159 I think or £299 together.
Cat back exhaust system from the likes of supersprint won't give you much more horsepower but should give you slightly better throttle response.
Fast road cams will give more power as well if you're really serious.
Orrrrrrrrr turbo/supercharge it
Either that or condsider upgrading to a 1.4L taking all other costs into account for what you get in return it sometimes works out the best option.
A 1.4L will be higher insurance and lower mpg. But any of the above mods mean the same thing.
Some people like to play with small engines though and see how far they can go with them.
Search around for the supercharged 1.2L Mk1 Punto I think it topped out at over 145BHP.
Let us know how you get on though
I was wondering is it possible to just buy a new Fiat GP 1.4 16v engine (a couple of hundred quid I'm guessing) and put it into a 1.2 GP or would too many problems arise?Fast road cams will give more power as well if you're really serious.

Because a large reason people want to increase the power on their 1.2/1.4 8v is because they have put other mods on there car such as lowering/spoilers/badges/grilles etc... and know if they are to sell and buy a "1.4 16v" they won't get there money back on the after market parts.
Also whats a road cam and how much gains are we talking about?

Damn good advice. People underestimate the effects put onto the differential and gearbox. Look what happened to "GrandeJ's" gearbox
. Even the stronger 1.4 16v ones suffer from this once tuned and running on 17" wheels. I'll be on my third gearbox in a few days (albeit its not a GP "Punto mk2b" but has exactly the same running gear).GSR do a remap for £199. Induction kit is £159 I think or £299 together.
Pretty much spot on a full system leaving the standard cat in place in the manifold is the best option and will give an extra 3-4bhpish combined with GSR and Remap.
Yes these work well 1.2 8v's seem to be best going down the N/A route
. Just remember to get a remap at same time to get them to work properlyOrrrrrrrrr turbo/supercharge it
Nice idea and very fun but not something that should be done to a 'daily runner' as it will hurt reliability etc ruin the warranty.
That was a 1.2 16v Unit with 80bhp as standard. Forced induction 1.2 8v's can expect about 120bhp.

A engine brand new from fiat would be in the region of 1800GBP-2200GBP. They charge 1100GBP just for a 'Remanufactured' Gearbox!!
It replaces the standard camshaft that Fiat provides with one with a sharper deeper angle. This mean the valves open further and stay open longer providing more power. This also required a ECU remap to make best use of it. GSR charge 186GBP on an exchange basis. I'm thinking about these on my 1.4 16v should hit about 130bhp :slayer: :devil:.
You can get them cheaper secondhand. if you shop around for a write off thats been is a side or rear impact the engine should be ok.
You'll still need the gearbox as well as it's stronger on the 1.4's plus the ECU, I'm guessing wiring loom as the 1.4 16V is a slightly different engine design and possibly the mounts if they are a different design.
I don't know if the mounting points would be same or not.
Would also have to consider if the standard rad can provide enough cooling, and if your brakes/suspension/tyres etc are up to the job.
Taking all the time and cost into account it can be done, but it is often much cheaper and more reliable to get a factory unit thats been set up already
Oh
Sounds interesting, 130bhp on a 1.4 16v is pretty darn good, so they charge £186 for the camshaft and then £200 for the remap? Do you think it would be worth it on a 1.2 and what about warranty issues?

Yes im aware you can get them second hand but I thought you were implying new as you said 'from fiat'.
Yes you'd need the 1.4 16v ECU and wiring loom IIRC (not sure what the loom is like on the 1.2 8v). And as you said gearbox. The engine mounts are the same just use the ones that come with the new engine.
Yes as you said you would also have to upgrade ancillaries such as the rad, brakes suspension should be fine.
And yes as with all engine transplants that are not "like for like" you will get 'issues' and loose reliability and warranty etc. Also have to inform DVLA to update your V5 and VED band etc.

Yes mine should be 130bhp ish after cams. I currently have a GSR induction kit and Red Dot remap and im nearly at 120bhp. New Supersprint exhaust and Cam's (I need two because its 16v which is DOHC) should see me 130bhp+.
As for warranty I think it would void the warranty on your whole engine
. Depends what the problem is really. Not really sure about the gains on the 1.2 8v if you send a PM to 'Oldschool' he is actually the guy who runs GSR and he is the technical wizard when it comes to Fiat tuning :worship: :devil:

He's a legend within the world of fiat tuning...all hail oldschool! :worship:
Just had another thought lol.
Smaller wheels make a car accelerate better, so not sure why people are fitting 17's to a 1.2 not going to make the car go any faster.
Could try putting lower profile tyres on the 15's and dropping the suspension.
Improved acceleration, handling, and looks all in 1
Could always try to lighten the car as well for performance.
Can of tyre fix instead of spare, carbon bonnet etc etc.

Yeah but when most people get 17's they get lower profile tyres as you have said, and so the overall tyre circumference is the same and sometimes even lower than standard 15's.Just had another thought lol.

Extra width on 17" tyres creates extra rolling resistance and can bugger the diff though.
1.2 gearbags don't seem to be very strong. I decided against a re-map after reading a few horror stories.
Don't have a grand to blow if it goes wrong.:yum:
