This summer I'm gonna have a couple grand to spend and being the type of person I am, I have to spend it on an engine and I know some of you are gonna think this is stupid, but its different, and they are my plans. So dont knock them, bear with me and help me out please. Or dont reply, I dont want this thread to turn into some noob war with "with that money you can drop in a b16". or "might aswell go FI and turbo that bitch". No
So now that that is clear, heres the plans:
*Depending on the condition of the block I have yet to pull it may be bored 30 over, if the out of round is decent and honing can cure it, thats as far as I will go.
*Converted to a dry sump oil system
*Solid motor mounts
Completely rebuilt with 10.5 pistons *forged rods* and a balanced crank, because I'm sure its capable of holding up to 300hp.
*Fairly wild headwork on both intake and exhaust, going a little more than an average port job, but not by much obviously.
*Cam from comp cams stage 2
*Doubt I will deck the head, but if its neccesary I will (doubtful still)
*Custom intake manifold with runners tuned at 4200rpmish
*4bbl carb (not sure of which vehicle it will be off, but small v8 more than likely, so I dont drown it out too much)
*150 wet shot nitrous kit, with the wet coming from an external fuel cell carrying 127octane racing fuel only
*Custom exhaust 2.25" near-mandrel (how I can mandrel bend myself which is very close, I lose maybe 7% during the bend from doing it my way with sand), from a custom 4-1 header into 2 long resonators. Hopefully no muffler, but loud will be ok.
*Valve train will be very well done up aswell, again no research on this part yet. But not upping the stock redline, so I dont have to worry too much
*Lightened flywheel, either shaving on mine (which would be best) or an aftermarket one, and if I go aftermarket I will end up making it even harder on myself by getting a super light one.
*As for a clutch I'm undecided, anything with atleast 125% more friction than stock, so recommendations welcome
Also with the exhaust Ive developed a ram air type system for the exhaust, where basically the air gets rammed into the exhaust from a front "cold inlet" intake of 3" diamter going into the end of the exhaust, where the tip would be (which is going to be side exit, not going around the rear axle) to create a vacuum throughout the exhaust because of the high pressure entering the system near the end, with a 4" exit (split into 2 2" on each side to not look too agressive and try to hide it) the 2.25" part of the system will be low vacuum during higher speeds. Which by theory helps top end exhaust scavenging(sp)
I had initial plans of using an eaton m90 charger through a carb but with 7psi boost all the time I will reduce reliablilty for a daily driver. This car will be rough enough as a daily.
***NOTE*** *- Not sure about forged rods, I havent done any searching on that yet, so I dont know what (if any) is available for an a20 motor.
So as for the questions:
1) What is the stock crank rated for?
2) Stock rods?
3) What other options for cams do I have? Comp cams gave me a reasonable price on a re-grind, but any other options to check out would be awesome
4) What other pistons besides wiseco and diamond can I get? (I'm considering diamond, because of the price, and wiseco quoted me too much)
Any other questions will be posted as a new post
