CR bluetop EU

2 punktara: OK, but the 3 HP difference must come from something, and what firehawk said all ads-up; 3,15-3,20 cc more combustion chamber because of the pistons... because of that 9.4:1 CR and 3 HP less ..

2 firehawk: from where are those 9.4:1 CR pistons. ??

yes, it does make sense, the FWD used the lower comp pistons, and no cat and egr, gave them 121hp rather than 116hp.
My ae92, which is the early type with T-VIS, and is swiss spec, with cat and egr, comes as 115hp.
the later red top version with swiss spec, gave 112hp on the dyno, so perhaps this is the lowest hp 4ag version, red top WITH swiss-us-swedish spec?!
it makes sense, as the red top losses hp with low C/R pitons, while the non-cat Euro version gives the 100kw, aka 130hp.
Gee, the mystery finally resolved!
