well ive picked up my 2.0 16v in bits, i.e head off, sump off. now i want to play before i fit it. ive already though carbs and decided for them, what else is worth doing to squeese some power out of it?

is a rebore to a 2.1 really worth it? as i got a nice set of pistons with only 40K on them.

Ive thought of:-

Crank lighten and balanced, along with the flywheel, port n polish, cams. what else could i do?

Headwork
Cams
Good exhaust manifold

Rebore to 2.1 aint really worth it, unless you pick up a 2.1 block for cheap

its all in the gas flow aint it?

On a NA engine 100% yes.
More air/fuel you can get in (carbs/tbs,headwork,cams)
More you can pump out(headwork,good manifold/exhaust system)

=more power/torque

well, 44 views and 1 person helps :(

i think ill get on to my mate who can do gas flowing and de-coking. then get polishing on all the internal bits

Adam said it all really mate, cams and port and polish would do you some good, lightened flywheel and crank will help it rev up faster, bore it out to a 2.1 = more cc = more power but pistons to suit wont be cheap, carbs sound good but could need slight adjustments over time, where as throttle bodies are stick on and go (obviously management is needed to run them)

yea i dont really want management. i dont mix well with any kind of electrical stuff. it is the flat flywheel so would that be lighter anyway?

Yeah the flat type is lighter.
Bubba

ah no point realy lightening that then.

fair enoughlol. oh sh!t you wouldnt need a ecu as the ecu controls the fuel and air ect.
sorry i had a blond moment:tard:

head work cams and if going for carbs try for 48s rather than 45s there what sbd used to use before throttleboddys became big and they recomend dellorto rather than weber there supposed to give smoother power but my weber 48s were fine, a must though is a decent exhaust manifold or you will strangle it

also that thread that was put up for cheap car parts had 1.6 cav dizzys new for £36 if there the round peg drive there the ones you need and a barging at that price

how come you need a 1.6 dizzy? whats wrong with the existing 2.0 one?

on webbers?
3D Ignition map???
So technically, he is right, depending on how you take care of the ignition side of things. ;)

Using the 1.6 cav dizzy requires no ignition management as it is a vac advance type dizzy.

To get a half decent flowed head, you are looking at at least £400 - but worth doing imo.

Just get it built well by a pro and get it balanced properly with a decent flywheel

get some throttle bodies if you can afford it as carbs are false economy tbh

get some throttle bodies if you can afford it as carbs are false economy tbh

On what grounds??

This is a common misconception - if they are set up properly and maintained well- they are great.

And at less than half the initial outlay of TBs, its an attractive alternative.

i cant afford tb's.

ah i see, 1.6 dizzy it is then
