i thought Aseries have a 50mm main and a 45mm rod journal size?

A12 Main bearing journal diameter, 49.964 mm to 49.957 mm [1.9671" to 1.9668"]
A12 Crankpin journal diameter, 44.947 mm to 44.961 mm [1.7706" to 1.7701"]

so i did some digging Pauter P/N NIS-190-480-1364F for custom rods specs are:
C-C BE BEW SE SEW
5.3700" 136.40mm|1.8901" 48.01mm| 0.9520" 24.18mm| 0.7480" 19.00mm |0.9000" 22.86mm

i also took a look at some crower rods. i got a set of their fiat 128 rods on clearance for $150. i have access to a machine shop with a surface grinder fitted with a magnetic chuck that i plan on using for this project. so 1.00"-0.9520"=.048"=1.2192mm surface grinding ~.6mm on each side seems very possible. i am currently contacting various piston company(ross,wiseco,CP) to see if a 22.5mm compression height and 22mm pin is even possible. i think with a piston that size i may have to experiment with a 2 ring piston.

from what i know a longer rod and shorter pistons will allow me to rev faster by increasing rod to stroke ratio and allow me to run lighter pistons with a shorter skirt.

are there any down sides to using a longer rod and shorter piston? the only one i can think of is possible increased cylinder ware.

im trying to see if fiat 128 rods will fit without tearing down my block just yet.anyone have the BE Bore and BE\PE width of the stock aeries con-rod. the fiat 128 has a 45.52mm rod journal diameter and company like crower and manley have them on shelf. rather then ordering custom rods for 1-2k.

the con rod i want to fit has the following specs
c to c BE bore BE width pin dia
5.060 1.914 1.000 0.866

so if the Base width will fit the aseries. all i would need is to make these work on an a12 is to a source a motorcycle piston with a 22.5mm compression height and 22mm pin have have a custom one made as i am trying to build a high rpm\boost engine i will need a forged piston anyways

so i won a bid on eBay for a h95(swirl port) but its eBay so i received a different part then pictured and listed a h72 head came in the mail.

upon removing the valves for a port and polish there is a huge hole/dip in each exhaust port making me believe its h77?

How can i effectively port this to be efficient as possible? do i try and tig weld it shut or do i just normaly polish it. can any explain why they would do this?

i cant seem to find valves that are 103.8mm long only the 100mm vairaint.

A13 h62 head help?

Hey guys I was able to source a new in box a13 h62 head. I am trying to find valves for it now. The h62 uses a14 valves correct? And a14&15 use the same size also? All the valves I can find are for the a14&15 but they say the length is 3.931" -99.84mm. According to the tech wiki a13 h62 uses 103.5mm I'm guessing these valves do not interchange correct?

Also I made a mistake in Machining my flanges. I machined to fit a14 instead of 13 by accident can this be ported out or will I hit a water jacket?

i've been looking for a rear end to replace my h145 once i get my turboed a12 running. i don't really want to change the PCD. i'm having trouble finding any H165\H190 in CA,USA. but i did find this https://losangeles.craigslist.org/wst/pts/5430924559.html
it is about 1" shorter then the H145 but i'm afraid of the 3.5 ratio being to high as i don't have any experience on this. this car is being built with the intention to drift so im sure the H145 wont hold up to hard turbo abuse.

Carbs are already turbo ready all I have to do is rejet, plug float vent tubes, and use boost fuel pressure regulator.

If I change to a more conventional setup I would have to change pistons, cam, carb, intake manifold, turbo manifold, new intercooler. That's a lot more work then just a big J pipe around the tranny. I could be wrong though.

I'm just working with what I have and that's a NA engine with a low compression ratio. About 9/1'i think maybe less Cam card says I require 10.5/1 at least. So I planed the turbo to have low boost in the mid rev range and high boost at 5k+. It might not be the best build but I'll be happy if I can just drive it up a hill with a 60% slope not being at 6k+.
