What engine should I go for?

[qstoria]

tell me about it!!

And finally, instead of going with the cryo'd crank, forged pistons, and rods (which is overkill if your staying NA), Up the compression ratio by milling the head or block (not sure which) or using a thiner head gasket.

Silly me, i take it u wanna do the bottom end aswell so u can raise the rev limit above what stock internals can handle. Maby just do all the head work and ecu these holidays (if u got cash left over do bolt ons like exhaust and intake stuff), then wait till next years holidays before u crack open the block?

i think it'd be better to just do the whole build (head and bottom end) at once rather than doing one before the other.
presumably you'll be building the head based upon the specs of the built bottom end and vice versa. if you build the head first but leave the bottom end stock you'll driving around with an engine thats aeffectively mismatched and not exactly running spot on.
imho you'd be better off waiting until you can defanitly afford to do both and do it all at once, that way you'll more likely achieve a better build through a (assuming) well matched combination of parts and you'll also save money not having to pull the thing apart twice.
anyway, i thought this was a spare engine so really wont be run until finished anyway?

Ahh yeah, i keep forgetting about that.

i just want him to get a car up and running

You just want to find out the MIVEC Vs VTEC thing when you get your K20A
You know MIVEC is the boss


Muzz, I have a 6A12 in my car now, and another 6A12 in a workshop in pieces.
I would rather do bottom end now before doing top end. The heads have been ported and polished already BTW
The reason I want to do bottom end, is that I will get valve springs as well, and that means when I do cam swap heads don't come off etc
And, most importantly, cams are about $1800 for my engine
So, I want to make sure I have the bottom end to go with some fairly wild cams. Basically, I see my bottom end as the foundation of the motor. The better I build it now (while it is apart anyway) the more crazy I can go later.

However, at the same time what I would hate is to spend 3-4K reinforcing the bottom end with plans to do cams, intake etc and end up not doing any of this (basically, have forged internals when the stock ones would do just as good a job)

I am in the process of trying to get the RPW 2.5
If someone buys my rebuilt MIVEC motor then I might go for the 2.5
It will run stock cams etc, but will make it more affordable and I can upgrade cams later. Also saves me a few grand in not needing to put the DC5R box into my car as the 2.5 will have plenty torque with just a 5 speed

should be interesting to see how they go. thats if we ever get our cars back

[sivic]

should be interesting to see how they go.

wont be very fair running a built 6A12 against a stock K20A though will it?

crack open the K20 and then see how it goes

either way, keen to see the end result of this car

[bal]

k20 has jdm internals, 2.5' exhust and aftermarket header also it is in a 89 crx so its a fair bit lighter

so i think it will have alot to do with driving ablity

[Muzz]

ooohhh sounds like some good competition! cant wait to see the results.
