200 whp NA tC is very possible. Larger injectors (440 cc+), I/H/E, Fuel mapping, Fuel Pump, Motor mounts, Bushings, Ignition, Running Higher compression through blue printing, throttle body, port and polish, bore out the cylinders (I don't like that idea one bit, but hey just giving some options). Psshaw. Granted expensive. But not as hard as people are making it sound. BUT you will not be running anywhere NEAR 29 mph highway after modding your tC for 200 whp NA.


Now that I am thinking. if you did bore out the tC to like a 2.6 liter, running 11-1 compression ratio (like the rsx-s) larger injectors, Fuel pump, fuel mapping, I/H/E, Port & Polishing, Ignition, Motor mounts, Throttle body.... I wouldn't be suprised to see 220 whp+

yeah and it work be functional for maybe a day or so then you would throw a rod like ron jeremy.


and wtf is fuel mapping? are you talking about tuning the car with an emanage or similar? LOL

motor mounts and bushings wouldn't give you any hp gains either.

if you did change the engine that much you would have to go complete standalone management and throw your stock ecu in the trash can.

matty-tC

not to mention that you don't gain compression through blueprinting.....

TimmyT

Motormounts and bushings won't give you horsepower, but it will improve the x-fer of power to the wheels. Through blue-printing you can adjust the travel of the piston heads (increasing/decreasing compression ratios) Fuel mapping. is air/fuel ratios (yes this involves computers). yes you would need a standalone. new internals. clutch. Lots and lots of stuff, But I never said it was gonna be cheap. Just said its possible.

matty-tC

what are you talking about "adjusting the travel" ?

what are you adjusting? are you stretching the rods or something? have you ever done an engine assembly?

TimmyT

Do you ever wonder why SOME tC's stock have more HP to the wheels vs. Other tC's stock?.... Go find that out then you will know what I'm talkin about.

matty-tC

run a compression test on them. I 100% GUARANTEE that they aren't running 11:1 compression

if you're just going from heresay about the blueprinting you can stop now.

and its the same with all cars. there are going to be differences in horsepower. they're called factory freaks. it happens all the time.

Slight differences in stock horsepower can also occur by how the ECU "learns" your driving habits. If you were conservative during break-in, the ECU might give you conservative fuel maps. If you drove your ride like a bat-outta-hell when you got it, the ECU will tend to have a more aggressive map.

Boring of our cylinders is difficult, re-sleeving is more probable and a more effective way of increasing displacement. All stock tC's have 9.6:1 compression, plain and simple.

Also if you plan to increase the CR to say 11:1 or even 12:1 for a high horsepower N/A, you might want to look at a blockguard and/or reinforcing the waterjackets since we have an open-deck designed block.

In the end, the fact remains that 90% of this is gonna need to be custom fabricated and is gonna cost mucho $$$$$$. Give it time and more options will be available.

shidosha01

I agree. A vvti controller, port / polished heads, headers, CAI, cat back exhaust, upgraded clutch, lightened flywheel, and high compression forged pistons may get it close to a 200whp naturally aspirated tC. That would be awesome wouldn't it?

engifineer

And if you plan on raising the compression ratio.. I would only reccomend it if you are not going with FI later on. If you decide to slap a big turbo on later, you will be trying to reduce that CR again.

matty-tC

it would suck when someone with a $3k zpi kit blows by you

hahaitzskippy

ya but the ZPI puts 250 hp and not 200 hahah

czardante

the ground kit on dyno makes 9 horsepower, and the dc headers with the cat gone and 2inch pipe into trd, k&n cai, should clear the 160 to the 185 to the ground horsepower.Import tuner mag did just cold air and exhuast and headers brought it up to 156 horsepower to the ground, same with sport compact mag, and they kept there cat, and i am running with the apexi grounding kit.so it is possible to reach 200 to the ground with out supercharger, i order the new throttle body from alpha werks, so on the 18th i will post my dyno numbers

matty-tC

i want to see the dyno that shows grounding makes 9 horespower

jmiller20874

Man, someone is really settin' themselves up for a letdown. With the setup you have, you will maybe, MAYBE have 185hp at the crank but certainly not at the wheels. The Alphawerks car with I/H/E and TB are doing a little over 160whp. A grounding kit is not going to give you 9whp on an economy 4 cylinder engine, it's impossible. Any manufactuer that tells you otherwise is taking you for a sucker.

oldman

last voltage stabalizer kit I saw did .5 WHP, meaning it was unmeasurable. The tC has coil over plug, there is no easy way to get more spark even if more spark is needed, which it is not.

matty-tC

if the car wasn't grounded at all then you put the ground kit on then i could POSSIBLY see 9 crank horsepower but 9whp from oem to aftermarket... no way!

czardante

they did the dyno on a honda b16a and apexi gained 9 horsepower, know i am not saying that it will give me 9 horsepower which i hope it does like it did to the honda, but it has the possiblity to give me 9 horsepower, i will even spend money on a dyno before and after if you want me to?I will make my car 200 horsepower to the ground without any goodies.But the company is saying they could not even believe it at first but they have the dyno on it.

what the ____ is this thread coming to? lol

matty-tC

oh by the way an all motor 200whp tc can be built. its just too expensive for anyone to be dumb enough to build it
