A backbox is a rear upright section of a pinball machine, incorporating the score display.
I Had the same problem with mine, it`s basically some corrosion coming loose from your backbox, i just pulled mine off and there was no actual damage to the backbox
yes
In the backbox on aux board attached to sound board. They call it a balance control. It is small. The backside of my swig out backbox display panel has a sound diagram on it.
A backglass is an upright graphic panel moutned on the front of the backbox of a pinball machine, decorated with game artwork.
If you're talking about a regular pinball machine you'd need to open the backbox and take the ROMs out then hook them up to your computer and reprogram them, have fun with it!
2To be honest if you oversize your exhaust on an N/A car then you risk reducing the "backpressure" to the engine and hence reduce the overall performance. Just by changing the backbox on a 1995 to 1999 Hyundai Accent / Excell on a stock engine will change the "power band" from about 2k RPM to about 4k RPM. By getting the TB mod you will hopefully negate the larger exhaust backpressure reduction, but for a 2.0 litre conversion you will need to referr to www.performancehyundai.com ;)I put a 2L late model excel engine in my 92 excel(1.8L) not sure the difference between elantra and excel but all i did was kept the original "juicy bits" like radiator ECU and gearbox ect. and everythign fit perfectly, no over pressure or anything.
