Supercharging a mk1 1.4i

[playa69]

Hi Guys

I have this idea, it has been asked before, but met with alot of the same answers, go 2L 8v, Go ABF, Go turbo etc.

what I am thinking of doing is get a mini cooper supercharger and strap it onto my motor. looking at low boost, maybe 0.4

so what I would need ...
Supercharger
boost pipes
brackets made up
copper gasket to drop compression
management system, how will the standard system cope, or not at all?
is the intercooler optional?

any advice?

There is no replacement for displacement..

[playa69]

i know that but would like to keep my standard motor.

uhm...

Not much gonna be left standard if you're adding boost to a 1.4i hey...

How deep are your pockets?

Would be interesting and unique, but don't expect big power.
Stock management will not handle as it was never intended for boost.
Intercooler in my mind should be a must instead of optional on any force fed application

i do not expect big power, just a bit more power. would the stock internals be ok on low boost?

In all honesty, you will spend 20-30K at least to do that mod, and will NOT make decent power or torque.
If you want to keep the motor, bore it out to 1.8 or 2.0 (has been done many times to 1.4 motors), and make more power than a 'charged 1.4, just saying.

Not 100% sure but on low boost like that it should be Ok especially since you will not make mad torque numbers. The precision citi's ran 0.4 bar with their turbo conversions and I beleive those all run stock internals

can soneone please post prices on the above

If you have to ask prices then you can't afford it. FULL STOP.

very nice and usefull reply .. so you just buy things without looking at prices???

Whatever you think your budget will be.... DOUBLE IT (and have another 20% just in case)

I learnt that the hard way...

It will be a very unique conversion though...

If I may, I know everybody has told you go 2.0 route. But is this your daily drive? If so, you need to think very carefully about what you want to do. If you go 2.0 n/a route, you will have very nice, reliable power. I'm not saying that the supercharged route won't be reliable, but if something breaks, you've got trouble, especially on your daily.

it is my daily and includes regular long distance driving.

[panic-mechanic]

Don't do that to your daily you depend on.

Supercharger - Depends on charger you using but anything From 5K upwards
boost pipes - 2K on doing a proper job also you going to run direct into the intake or through an IC - if cooler then add an extra R800-1200
brackets made up - R300
copper gasket to drop compression - not an ideal way to drop CC but you might not have to drop CC as detonation happens usualy lower down in the rev range so if you going turbo then yes its needed else if you going sc leave CC stock for now and manage boost via the pulley. remember that with an sc u making max power at max rpm so linear power curve
management system - R 2500 for a dicktator or similar setup
new Belt and tensioner

then you need to think of injectors to use and fuel pump/regulator boost dependant, also are the conrods strong enough in the stock setup?

its the small little stuff that becomes expensive - but If I were you I would go the 2L route and then if you want more either turbo or SC that setup and dont do it on a daily as said above

You can pick up a 4AGZE SC12 off the 9000rmp forum for +-1k
Make an altenator bracket to lower it and a bracket for the SC.
You wont need to run a gasket if you running 0.4 on a SC12 It will hold, If its really worrying, run some toluene to stop chances detonation.
Have a friend running a Eaton M64 on a stock 2E motor with some Toluene and its been running for a year perfectly, in fact its pretty quick too.
Makes 110wkw & 240nm at 0.3bar - this was on Nascar's Dyno.

You will need management, go Gotech if you can as Dicktator like big injectors for the setup to run well.

Ps, my mate says he has a SC12 for sale. He will be able to talk you through it.

[mad dog]

Save some money up and then start shopping. Real nice one would be the Polo gti 1.4 conversion?

[playa69]

Thank a lot for all the info guys. Will think carefully as it seems like this is not a good thing to do to my daily.

[mad dog]

Modding is like a drug!!!! It never ends.

I spent close to R200k on a car....at the end sold it for 48k.......

If you want a race car, start fron scratch or buy something decent...

Just a reminder, you will never see that money again.

[smash!!]

hey i did an sc 12 on my 2 l 8v had quite a few problems in the end took it off and then just saved up built 2l 16v turbo motor and i couldnt be more happier !!! its really nice to keep stock motor but you would be alot happier in my opinion with going 2l 8v or boaring it to a bigger cc and then going turbo or sc later on.

and as me and my friends learnt the hard way dont mess with your daily drive makes you stress for nothing when you have problems.
