With out knowing exactly i would say you can probably make the power and torque out of the 4 cylinder with some after market stuff and it will save you a lot of head aches with the fitting and wiring a V6 or a V8 but if you can do it go for it i would be a beast.
The required fuel pressure varies from year, make, model and engine size. An example would be, a 2000 Chevrolet Blazer with the 4.3L engine would require 60 to 66 psi for the fuel system to operate correctly. Any more or less than that the engine would run poorly if at all.
check your accelerator...
um they became less important?
This would decrease the efficiency of the engine because less air would be able to enter.
There are many body modifications available now with the advert of modern surgery. Extreme modifications like skin implants to create horns or ridges in the skin, to the less obvious like split ear lobes have all become more common to see in everyday life.
You will not get all the nutrins you need a day
Possible? Yes. Advisable? No. It would be much easier and involve less expense to go back with the OEM engine. Remember if you switch to a 350 Chevy engine you will have to change way more than just the engine. Major modifications will need to be made. You will either need a Chevy transmission or a conversion bell housing, if they exist. Drive shaft will also need to be changed., just to name a few of the many things you will need to modify. Save yourself the headache and the expense. Install a Ford V8.
You can, but it would be less expensive and time consuming to just buy a moped.
Yes the Golf Mk4 can take an offset of between 35 to 42 with no modifications, anything more or less you will need spacers or body modifications! check this site out: http://www.carlsalter.com/wheel_fitments.html
It needs to be Re-Set.. Most places can do it for no cost. takes less than 10 seconds.
Not sure when you say low speed. Not knowing what your driveline ratio is I will just use some basic numbers .If 20 MPH is your speed and you were in first gear your engine RPM's would be 3000, if you were in second gear at 20MPH your engine RPM's would be 2500 , if you were in third gear at 20MPH your engine RPM's would be 2000. A difference of 1000 RPM's from low to high gear. Lower engine RPM's less fuel used.
Why the fuel consumption is less in 4 stroke engine as compared to 2 stroke engine
