old vs new

[BMW ///MPOWER]

Ok i was reading up on the 1g's and i notice that there 1.8L had 125 vs. our 122. what gives? why the old engines more powerful? what did they change? software? different exhuast?

[NegatiZE]

It's a different engine altogether. The B-series block is made out of cast iron instead of aluminum in the F-series. It's also much stronger, happier to rev engine and holds boost better.

Actually, I believe they're both iron block. Totally different engines though. Plus, an additional catalytic converter or so, OBDII, etc.

I think they changed to F-series for the 3rd gen because of its higher torque output in NA form.

My 97 has 122hp.
If you notice, the second gen BPs have 3 less HP but 3 more pound feet of torque.
The EGT had 12 hp didn't they??
I seem to recall reading somewhere that the FP-DE likes to rev more than the FS-DE and its got a better torque curve.

so the 1g's have more durable engines that the 3g 1.8L? so are you saying its not too good to be reving my engine alot? i plan on autoXing my 3g and since im new to proteges i dont know if i will blow my motor, would you recommend to not autoX my 1.8L??

[ZoomZoomH]

I WILL RECOMMEND you to autox your 3rd gen, as it has one of the best chassis in its class (save for the lack of camber adjustment of course), and the 1.8 FPDE is more than capable of handling the stress of autoxing (see sig lol)

go ahead and autox your 1.8, you'll enjoy it

and Jas00x on this forum has probably the most experience in autoxing a 3rd Gen ES, give him a PM if you still have questions

alright thats what i wanted to hear, so this FPDE in my 99es is more up to the task of autoXing? alrighty then.
