1) does the original gearbox cum wit LSD?If nt what are the brand to use?
Yes the stock FD comes with the standard Torque Sensing LSD. This should suffice unless you have a full time race car.
2) Is the 20b a driect conversion to fd3,do i have to convert any mounting or bracket.
It is not a direct bolt on. There is plenty of fabrication that is required and to the extent of pushing back transmission by 5-6 inches. If finance is not a problem i would reccomend getting a special sub-frame that will save you the hassle of trying to mess around with you stock engine mounts.
3) The 2ob can at least produce hw many bhp with the single tubro.
The sky is the limit. As long as you have the fuel modifications that can supply fuel you can hit most anything bar that turbo as well as porting and engine health is important.
4) Hw much will it at least cost,the engine wit the install.
Lets just say its not as simple as getting a halfcut and bolting it in. You will definitely need to rebuild the engine. Turbo as well as manifolds, b/off, w/gate/ I/c, Radiator (i suppose you'd be able to get away with stock,Aftermarket Ecu, Fuel pump as well as lines, Injectors. Then once done you'd want to make sure its tuned and does now blow due to insuffcient A/F.
There are many ways to doing things, you can do it right once or not do it at all. Rebuild- 5-8k, Ecu-5-7k,Turbo-4-5k, Halfcut-7k. Thats roughly how much you would need. Dont forget to have spare cash laying around in case of emergency.
5) wat e max rpm can it go if e tuning is gd?
this again is dependent on your engine mods (again, how much you're willing to spend)
Good luck and keep us posted.
