My B204L 900 (MY 1996) given up after a long uphill hard pull about 14 months ago, "ta.ta.ta" sounds came from engine and car slowly stopped, I feel the engine internals was jammed, could be the rod bearing or so...finally I made up my mind to re-build it after 14 month of hesitation...

Why don't I take the chance to mod it up as a project car, but I dont have much experience to mod a T5/B2X4 engine, all the while my experience was with B207R and B235R.... so your suggestion are all welcoming!

Here is what I have collected for the kick off the project, both hardware and questions:
1. B234 Internals (piston, rod, crankshaft) from a 1996 9000 (Im not sure it is E, L or R) but they should all have the same internals, correct me if im wrong?

2. A B235R cylinder head assembly and a B205E head assembly, and my B204L head (should be the same as B234 head)assembly...question here is, which head/or parts combination are the best for performance? use the B235R head assembly, or hybrid the B235R valves with B204 camshaft ?

3. Heard some people remove the balance shaft, should I do the same? what would be the benefit of doing so?

4. Will the factory 4-speed Gbox cop well with this project upgrade? If it wont, any advices please?

5. Plan to use the TD04-15T from the B235R mod to 19T, machine the exhaust housing to 6cm^2, any better suggession?

6. Any suggestions what injector to use?

7. Exhaust - downpipe only or full pipe? Personally I prefer quieter cars, more sleeper effect : )

8. Anything else you think I missed, or should do? please add on... of cause the ECU tune, that would be the last job once engine is rebuilt.

Here is a humble photo of my 900. Thank youuuu!
