BOOST a s2k
i wanna know if a spoon S2K engine is available in the US... and i wanna know how i can boost a s2k.. i knwo its possible and ive seen it done.. but i have a Q on how to lower the compression ratio... cause since the s2k has such a high compression ratio bla bla.. i doubt it'll last more than a year if i boost it.. i'm thinkin about trying to get my hands on a spoon engine... and try lowering the compression and boosting...
If you got 10 grand, you too can own a Spoon Engine F20C1..good luck..but the compression ratio will even be higher, but you will be able to rev to 10 or 11 grand also...
Spoon engines are built for NA power. The things you want to do for an NA motor are often diametrically opposed to what you'd want to do for a boosted motor. You'd be much, much better off using the money you'd spend on a spoon motor to pay a capable engine builder to build you a motor for boost.

God, the compression on those things is really high...heck you'll be spending more on preparing the engine for the turbos than the turbos themself.

Get a nice turbo kit made with a big T3/T4.. since the S2k revs to 9k you want to get a turbo with alot of top end.. Go for custom specs.. Get some big *** injectors, a stand alone fuel management system, maybe pistons/rods and i bet you could make 400whp at 15psi... dont bother with a spoon motor either, for the price of the motor alone you could fabricate a turbo kit and build the motor.. If you have 10k to drop into an S2k i bet you could make it a daily driven low 11sec car...

I question whether you'd still want to / be able to run an S2K motor 9K with 15psi of boost on it, though. Especially if you wanted it reliable.

My thinking is this, if a built B18C can run 15psi to redline and stay reliable, why couldnt a built F20C do the same? stock for stock isnt the F20C even a better built motor...
I think the S2k has alot of potential, it should be able to do what a hybrid hatch can do with ease since it has 1)more displacement 2)revs to 9k 3) is RWD 4) is 6spd.. There are lots of people who have daily driven 11sec hatch backs and i think if u apply the routes used in those to an S2k u will be even better off..
yea... i'm kinda dissapointed that spoon only makes all motor engines.. i know all motor will be mroe reliable.. but just the turbo... blow off valve.. its addicting as hell... and i like the s2k anad the way it handles.. but i want a lil more torque.. cause its pretty slow from stop... i juss wnat more KIK from stop... how reliable will it be if i go ahead and make the mods on my engine? build it and lower the compression.. i know boost is overall not good for ur car but there is a point where its pretty reliable...
wats the point of going FI on a Spoon engine. The cams are high lift; the pistons have a higher Cr then the Stock F20c pistons. If u want to boost the F20c, u';ll need low cr slugs, rods, close the deck if its an open deck design (dunno if it is or not), upgrade fuel/ignition system and run a stand-alone ecu. If u wanna opt out for a cheaper way; by-pass the block building and get a thicker head gasket..though, u wont be able to boost higher then 8-9psi (not safe if u do).
The F20C is a high, high compression motor meant for N/A use..it might sound hypocritical of me when i say this because im using a B18C5 with a turbo; but take it from me that its alot of maintenance.

If you are spending the money you might as well spend it on turbo cause you arent gonna go fast in the strait line allmotor.. and if u want low end torque dont buy a honda.. many people will say the S2k is a roadster and not made for drag racing.. thats why i would even say go allmotor with that car if u r just making it better for road racing.. but strait line wise, turbo is where its at
it is very simple. You don't need to rebuild the motor to lower the CR and get away with moderate boost, full timing advance, and make reliable power without detonation, all you need is a well designed head gasket to increase the thickness.
Some of the pitfalls:
offset cam timing: fixable with cam gears
stretched timing belt
less power on the low end
Benefits:
full timing advance will give max charge burn efficiency without burning up the valves by going into retardation from stock timing
full boost, no ping, full timing, max power
more power is made with timing advance than static cr any day with regards to reliable boosting.
If you have an S2K, are serious about boosting this, have the bore stroke and CR specs, e-mail me, I may be inclined to design one for you.
