Hello all.
I am planning to purchase the AA type 4 performance build kit.
They don't tell exactly what is included but I am pretty sure the kit includes 76mm crank /96mm pistons/ "h" rods

Plus all the other small items that can easily be forgotten...at least by me

A) Can factory fuel injection handle that upgrade ?

B) convenient CB calculator says around 73cc combustion chamber volume would give me a 8.9:1 ratio.
Is this a good ratio to aim for?
I am aiming for more low end power/ torque to deal with hills.
I don't want to wind out 2nd gear anymore.

I also plan on the following:

Web cam 107i

AMC 42/36 heads

Headers (A 1 sidewinder)

Exhaust ( A 1 heater box sidewinder)

If anyone could let me know if I can proceed with my i
plan or if I need to change something, that would be amazing.

I am currently on good terms with my "financial advisor"

Since my case is already open. Figured there would be no better time to upgrade things.

I know there is a lot of info here.
I hope it all makes sense.

Thanks everyone.

Perhaps I asked too many questions at once.

Can stock fuel pressure handle a 2200 build?

I’m not sure the stock ECU can adapt to a significant change of capacity. The fuel pump, regulator & perhaps even injectors might be okay. Switching to a tuneable ecu would give you plenty more adjustments. Potentially you could fit something like a speeduino inside a spare ECU casing, if you want a tidy install but you will have to figure out all the wiring/ sensor integration yourself.

If also not sure if you can open the chamber to 70+ CC but I’ve not done any research on that.

Morning.
I am just going to rebuild my stock motor, AMC 42 x 36 heads and maybe a cam. Just need to move on.
I found these guys on eBay.
Their injectors atomize way better than stock.
