Sigh.

The B230 16v conversion uses a B234 oil pump gear to run the aux shaft.

An oil pump gear... Does it? Are you sure about that?

If it's such an issue with the B234 why is it not an issue with the B230 16v conversion?

From Yoshifab:
Our kit includes the timing belt, tensioner, idler, and the mounting plate/hardware. You will need to acquire a 3rd 16v cam gear to drive the aux shaft. [....]

Dear gawd.

A cam gear is not an oil pump gear.

The cam gear on a B234 (#38 in pic) is wider than a regular B230 cam gear or auxiliary shaft gear, because the B234 / AQ171 timing belts are wider than B230 ones. So a third B234 cam gear (p/n 1378375) is needed to run the auxiliary shaft when doing a B230 16V.

If you look up the AQ171 versions of the engine, they also use a third 'cam' gear on the auxiliary shaft, p/n 855787, to perform the same function, albeit with different belts than Yoshifab uses.



JFTR, the oil pump pulley is seen in the picture above at #36. It's clearly different to #38.

"Proving you wrong bgpzfm142 is becoming tiring"

Seems to me your "LOT of research" on 16v conversions wasn't as comprehensive as a 5 minute google search could produce.

Again with the personal attacks, while being profoundly incorrect.... Try learning to tell the difference between a B234 cam gear and an oil pump pulley before replying.

Better still, just don't reply to me at all. Ever. Go pick your fight with someone else.

It's missing 0.3 of a litre. They are an ok motor, my s40 is still slower than my 122 and both rev out to 7k

That one is a T5 over 300 hp NA at 8500 rpm.

Just thinking out load.

I haven't seen many B4204 na projects ....but many T5 rods and pistons would be interchangeable.
Not sure if the weight would make up for the extra .3 litre. But size would give a better option of mounting it back for better weight distribution.
