I had no idea door construction was different, It’s a 1973 coupe. What is the difference in pre 73 models ?

dose anybody have any experience with removing these permanently. I’m talking about the bracket on the inside of the center of the door skin with some foam in some spots. I’m asking because one of the doors I have had it removed for rust repair and it’s now missing. I hope I do not have to source a new door just because that bracket is missing.

Saw this video on YouTube I don’t know if it’s already been posted. But this guy in Japan has some parts I never knew existed. Like titanium rods and tori spec head.
Torii

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

what's the condition of the a15 short block?

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?

sorry, i was talking about length just checked the wiki 100mm and 103.8
i cant seem to find valves that are 103.8mm long only the 100mm vairaint.




i just realized that the 100mm valves are 35mm wide.

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.
