Can anyone help with more bhp?

Hi! I am a new member

At the minute i am working on a 1.2i 8 valve engine and i am estamating
it to run at about 180- 190bhp no lie i will come to the spec in a minute let me start at the beginning well i had a bet with my brother to get a vauxhall corsa 1.2i 8 valve and get as much bhp as possible without changing the block as it is the block that holds the capacity of the engine bearing in mind he never said anything about getting the block rebord ha!
Enyway the spec i will start at the bottom of the engine and work up!
here we go.

The crank has totaly been reshaped to give a lower induction stroke and a higher lift to give more compression the block has been rebord to about 1.4 and the pistons have been replaced for low compression pistons
which cost me an arm and a leg working upwards there is a plate that go\'s between the block and the head 15mm tall so in turn can take more air in and also 2 head gaskets have to be used not to mention the custom head bolts made out of titanum moving up again (The cylinder head) is a 1.4 head which has been reported 3mm to give more intake/out and valves have all been reshaped for smooth intake the exhaust manifold is a 4 into 2 no cat straight throught exhaust system the inlet manifold has also been reshaped cam and followers have been replaced for kent cam set and last but not least the turbocharger it is off a mini cooper s
and the ecu is standard and will be upgraded but the engine is not in the car yet it is sat in my cella still got a lot of rebuilding to do yet! but most of the work is done i am estamating this engine will give about 180 - 190bhp
if anyone else can think of anything i have missed or haven\'t upgraded please let me know so please give me your thoughts!!

Regards, Mark!!

[quote=\"gn0mis\"]seems like a waste of money doing all that to a 1.2 8v engine imo but if you have the cash to do something like this then you must be completeley mad but I take my hat off to you for doing it anyway.

Also, thought the mini cooper s was supercharged, not turbo charged hense the \"s\"[/quote]

sorry my mistake! Mark

[quote=\"gn0mis\"]So do you actiually have this engine out and being built/worked on at the mo then and most of all, do you know exactly what youre doing? trying to get 180 brake out of a 45brake engine seems like one hell of a job, but then again, regal make a turbo kit for the 1.4 engine which apparently will give around 180brake once fitted, costs a bomb, around 3 grand or more I think, but you get everything you need with it including full stainless steel exhaust system with sports cat so you dont need to **** ass about when it comes to mot time with swapping everything around so that it\'ll pass.[/quote]

well so far it has cost me little over £1500 and it\'s not that am a rich boy
i do all the work myself the ally plate that go\'s between the block and the head cost me £300 and where i work they do mot\'s there so dont worry about mot LOL av got to go now cos i have 2 jobs and i finish in 15 minutes
So i will go in to more detail at some other time!

I have put a picture of the engine in members gallery but please note it is not complete yet and can anyone advise where i can put the supercharger
because i dont want to put it next to the exhaust due to heat reasons or maybe i could get a heat sheild?

If you have done all this work already, but you don\'t know the differnce between a turbo charger and a super charger!!!!

And basically it is not a 1.2 anymore but it is now a super-charged 1.4

Also what mounting kit have you made for the super chrger to fit onto the crank?

I have just got the charger throught today i have no idea how i am going to mount it but i have to change the pullys to 6 groved as the standed pullys have only got 1 grove if you know what i mean and if you look at the engine the engine mounting will also get in the way if you look to the left of the engine is there anybody else who has done this befor? as i would love to see so i could get some idea of how it is done if not i will just have work something out! so far i have been at this engine about 6 month and it\'s starting to p**s me off when i have completed the engine it will sit in my spare bedroom untill the car shell is finished so it will be about another 8 - 12 months seems forever away!
