how much hp could i get out of the ka with out turboing it, and wahts some thing would need to do that

[silviaNE]

port/polish head, cams, high compression pistions or mill the head, good header, CAI, pulleys, convert to electric fan, ect.

i imagine with some $$ you could get 200hp.

[Aries]

it's about $4500 to get to the 200rwhp mark N/A

[DR1FT3R]

ah but what a sweet mark it would be.

[nlzmo400r]

indeed, and 2oorwhp would feel very different than the 135-14o ish that the KA puts out stock, and especially since most 24os are s13s and have 1ook+ miles on them, they have lost some of their punch

What kinda torque, how much money, and how would the car be as a daily driver?

[spec-v5150]

didnt see it mentioned....http://www.racetep.com supposedly makes a 200HP n/a KA24 for like 3 or 4G's I looked into it when I had my Altima. I dont know if that is at the crank or wheel

[spec-v5150]

Here did some grunt work for you:

210 HP Normally Aspirated Street Engine Mods.

For those of you that want fun streetable power without all the expense of a Turbo system we have developed a great engine combination suitable for everyday driving on 93 octane pump gas.

Low to mid 14 second ¼ mile times without abusing your driveline or using Nitrous. For those of you hell bent on using Nitrous the JE Forged pistons and special Total-Seal Ring pack we use will easily handle 60-70 HP of NOS without too much worry. If you want a bottle only motor or plan on running a 100+ HP unit we can supply specially designed and coated Nitrous Pistons and valves.

All engines are done on your core or we can supply a core and sell it on an outright basis. Core cost is approx. $650.00. Shipping anywhere in the U.S. ranges from $150.00 to $250.00 for complete engines depending on where you are.

Complete Engine build-up includes….

· .040 overbore 10.5:1 JE Pistons

· Total-Seal Ring pack

· Race prepped stock rods with ARP bolts

· Detailed and Heat Treated crankshaft

· Lightened stock Flywheel

· Balanced and Blueprinted rotating assembly



· Race Ported, Flowed, CC’d Cylinder Head

· 3 Angle racing valve job with hand lap and back-cut

· Secondary Butterfly system removed.

· Intake manifold match ported.

· Throttle body opening enlarged for 65mm T/Body.

· Camshafts reground and indexed.

· Valves shimmed and adjusted.

· Heavy Duty Head Bolts.

· Felpro Gaskets



$3900.00 complete



Optional Upgrades:

Ceramic coat pistons for Nitrous use $49.00 ea

High Heat coat valves for Nitrous use $9.00 ea

Enlarge stock throttle body to 65mm $250.00

[lessthanjakejohn]

is that crank HP?

[Aries]

looks like crank HP to me.And with those ceramic coat pistons I'd never run more than a 50 shot.

[spec-v5150]

yeah most likely crank. If it were whp, that would be a high HP *** KA

looks like crank HP to me.And with those ceramic coat pistons I'd never run more than a 50 shot.

its not good to run nitrous with coated pistons?, please elaborate, thanks

[TomsMR2]

200rwhp on a NA is ALOT different than 200rwhp on a turbo. its allllll about powerband, not peak power.

[Aries]

its not good to run nitrous with coated pistons?, please elaborate, thanks

Forged pistons are for boost and nitrous.these coating are merely a coat of non stick much like a frying pan has. They don't protect against anything, and actually make the pistons easier to crack than cast pistons. Same goes with the coated valves for nitrous.

It's all a load of crap. Titanium valves are much better.

[nlzmo400r]

hmm, well then why do people even bother coating them if they do no good?, i mean its gotta protect against somthing?, heat, fricition..something

[TomsMR2]

the coating helps dissipate heat as well. toyota supercharged motors come with ceramic coated pistons.. and they're bulletproof.

[Exar-Kun]

no. a ceramic coating does NOT dissipate heat. THe idea of a ceramic coating is to keep heat from going into the piston, thusly lowering piston temps, the problem is that that heat has to go SOMEHWERE, either into the head, cylinder walls, or out as exhaust heat(where most of it goes) this is bad for turbos esspecially, because the head absorbed by the turbine is already immense.

just thought I would add that.

aries is right, get a good material forged piston, and valve(titanium, chromoly forged steel...) material and you'll be set.Now a low friction coating may prove usefull...but I dont have much data on how those work under boost.

-chetalso, toyota supercharged engines dont have to worry too much about exhaust temperatures, and every supercahrged toyota engine(old MR2) I've seen really worked up blows up with stock stuff anyway.

[TomsMR2]

^ the stock ECU is by FAR the limiting factor. it doesnt do well on mods, it has absolutely nothing to do with the engine. they like to advance timing when it sees weird boost, or just stop flowing fuel. its a management issue.

[nlzmo400r]

hmm, well then i really dont see the major benefits of coating the pistons

[lessthanjakejohn]

tom, have you seen this?

[themadscientist]

4A turbo, what's that going into? He needs to tighten his alternator belt though it must squeak bad.

[lessthanjakejohn]

MR2

[TomsMR2]

i believe thats brent picasso's beast..

thats just the 16v turbo.. theres a few 20v turbos running around now... all oldskool mr2's. all obsurdy fast

i do agree about the coating.. i dont think its worth it to go out of your way to have them coated.. if they're already done tho, i wouldnt be worrying about it.

[lessthanjakejohn]

just a 16v...haha

[TomsMR2]

ph33r teh 20v

[lessthanjakejohn]

hows bill strong's 20v turbo project goin?

[TomsMR2]

last i heard, its running in NA form. he said its gonna be a slooow buildup. hes slowly receiving parts etc etc. i think hes still waiting on the electromotive EMS.. i think its gonna be a while (year maybe) before its running in its 450 or so hp state.

[Evil98Silvia]

I would love to Have the 20v if was to toyota! 4 throttle bodies, 20 valves, look at you, most of you are stuck on nissan your got a headache thinking about this, lol. My buddy is huge on toyota, accualy alot of my buddies. My friend Berty has a 3sgte in his Mr2, ask what he has done, pretty much everything under the sun, hes about to do the turbo upgrade, he is running full potential boost on the stock one. As of now he is running low 11's stock suspension and tires =D. car is a sleeper.

always liked mr2s, never had the money for the toyotas i liked (i.e mr2s, mklV's) and even AE86s are expensive now
