After almost TWO YEARS, my favorit is now up and running. drives well and is quite reliable so i am now officially in the skoda family I've been drivin it for about 4 months now (didnt get to post about it earlier) and have done a couple minor stuff to it:

-new headlight bulbs, piston rings, brake rotors and pads, subwoofer....

however i hav future plans for it:

-new radio, lowering springs/coilovers, HID headlights etc. i hav been thinking about tuning it.. ive previously posted on this site a few times about turbo charging and engine swaps for my car but now i am definately sure about keepin this engine. but i need help in choosing parts for tuning. ive thought about it and came up with an idea of some stuff i need. your feedback is well appreciated:

- bike carbs (preferably from a r1/r6 carbs)

- custom intake manifold

- new headers( if it can be sourced)

- custom 2" exhaust piping

- forza/vibrant exhaust muffler

- ported and polished intake and exhaust

- electronic fuel pump

- cams.. what profile cams do i need to get? or should i use the standard cam setup?

- valves..what modifications is recommended for the valves, springs and the valve seat?

If you're prepared to go to those lengths, rather than bike carbs, what about going to electronic fuel injection on a Megasquirt ECU, or classic twin 40mm Webers or Dellortos?

Cams can be sourced, but you need to decide what your goal power output and drivability charactoristics are before you can select a cam. I could suggest a full race profile, but then it turns out you want a car for taking to the local cruise so an engine that does nothing below 5_000rpm is not what you want!

Thanks Ken. To be frank, i want the car to perform well; to be quite peepy and can overtake some cars when i need to :P . i have often thought of competing in circuit racing with the skoda, so it would be good to have some race profile stuff in the car. As for the carbs, the weber or the dellortos would perform better than the bike's/

I'm not sure whether bike carbs would give more power than a pair of car DCOs (Weber or Dellorto), but the bike carbs would mean doing your own development, whereas DCOs are a well-understood technology on 4-cylinder engines from 1300 up to 2300 cc, so you'd probably be able to get a set delivered pre-jetted.

Or as I say, port injection on a Megasquirt means the hardest part is choosing the right map and sizing injectors (and the Megasquirt site is pretty good for that stuff).

ok, i am looking at both options ( convert to injection or remaining carb), which one is more reliable? which one gives u better performance? which one gives you the better mpg.. im taking all these things into consideration. i hope you guys dont mind all these questions but i'm new to this so i'm looking for all the help that i can get. thanks

Carbs are less likely to fail completely, but more likely (at least with twins, or your bike carb idea) to need regular adjustment (balancing and simultaneity of butterfly movement) even when set up. The reverse is true of electronic controlled injection (and how likely it is to fail is dependant on how well the ECU was put together).

Injection will probably give better economy, and better performance/drivability everywhere except at peak power or torque revs, whichever the carb(s) are jetted for.

thanks alot guys. i think i'll be sticking with the carbs for now. all i hav to do now is find the right size carb for my liking and increase the compression ratio a tad bit. o before i forget, would i need a bigger or more powerful fuel pump to feed the carbs?

Maybe; how much fuel you need is a function of how much peak power you make. Afraid I don't know the formula though.

o ok.. been absent for a while with school and alll. car is due for some servicing so i will get to that soon.

one thing is f my to do list and thats the new radio.. i bought a pioneer DEH-P3000IB radio.. sounds better than my really old Blaupunkt radio..clean crisp audio..

Next on the list is lowering springs. The original spring seem to waring and has become soft. so now i'm looking for a set of lowering springs.looking to lower the car about 40-50mm.. havnt seen any spring that does it. help anyone?

bike carbs would be a far better proposistion in my opinion rather than dh's or dc's because you could source everything including the linkage from the same motorcycle. then just to a bit of bodging to make it fit..

and as for megasquirt, dont bother it's rubbish.. theoretically there's no reason that a carb engine cant make just as much power as an injected one so long as it's been tuned up properly

I'll agree that there's no reason why a carb engine can't make as much full throttle peak power as an injection one. I'd expect a properly set up port injection engine (and maybe even a throttle body injection unit) to make better power everywhere else, and have better drivability though.
