this is the reason i will never buy a used tc.

 

If you're asking questions like this then I sure wouldn't bother with nitrous... At least you didn't buy it yet. Keep reading and learning and make decisions based on what you know, not others suggestions... I don't mean to be a dick but you should really learn a lot more before just saying I'm gonna run this shot or that shot because before you know it you're gonna be stuck on a shoulder with a smoking engine, and that is not something I want to see happen to you..

I have a quick Question. My buddy just got a Civic SI. How can Honda pull almost 180hp out of their 2.0L motor and the tC only gets 161 out of a 2.4L. And don't tell me its vtec either because I wont believe that for a minute. I'm thinking they might have a higher compression ratio? We also have VVT-i witch is Toyos vtec but all the time, not just high RPM right?

 

It's not VTEC, especially. The lift cam in VTEC has an aggressive profile making a bigger boom. The compression is also higher in those cars.

We have VVT-i which is not Toyota's VTEC it's more like i-VTEC but even then the operation is different although they achieve roughly the same thing. Both VVT-i and regular i-VTEC have only a little to do with making power. What they do best is make the torque curve flatter. The i-VTEC in the A2 and similar engines Honda engines (K20A2, et al) has an extra cam lobe that replaces the regular lobes when VTEC "kicks in."

The tC's engine was made to power Camrys, RAV4s, and other pedestrian 4 cyl cars. It works well in the tC to make it sporty-ish because the tC is lighter than the cars the 2AZ was meant to power.

That's the main reason why we "only" get 161 bhp out of 2.4 liters. Let's remember now that Toyota got 180 bhp out of 1.8 liters in the 2ZZ-GE. The Celica GT-S was designed scoot quickly and also has lift cams like VTEC (for Toyota it's called VVTL-i.)

 

also, don't forget that horsepower is derived for torque times rpms/5252.

so while the tc only makes 161 at 6000 rpms, it makes alot more torque than the 2.0 ka honda engine, and the 1.8 liter celica gt-s motor. the reason why they make more horsepower is because they rev to about 8000 rpms, so more rpms and good torque means more horsepower.

 

I love my tc, but I have to face the fact that it's a 4 cl with 160 hp stock. I do what I can for more power. Drop a crate motor in it, or you can save ur money and make the pssssssh! sound when you shift.....lol

 

where exactly are you gonna get this "crate motor" lmfao

 

 

and in this crate is a built 2AZFE? ;)

 

build the motor NA (sleeve the block and everythin) and run a 150 shot...

 

yeah you can get BC cams and up the injectors with a standalone and pullys,header and good exhaust and intake and ti runs a lot better,but there is no crate motors for us.

Now if you can fabricate you can shoe in another motor.......M2 motoring put the turboed MR2 motor in the xD and it screams.....but they also have a pretty generous budget to play with.

 

is the latest trend on SL bringing threads back from the dead?

 

if you get a
4-2-1 header 15 hp
pulley 10 hp
CAI 5 hp
cat back 8hp
intake manifold 10 hp
Ported and polished head 5- 10 hp
stage 3 cams all motor 10 - 20 (depending on tune and supporting mods)
valves springs retainers guides seals
11.0 : 1 pistons (not sure but I've heard you get 10 hp more for every 1 compression you go up)
stroker kit while you've taken your engine apart to install this stuff 20 - 30 depending on current mods to engine
NOS 50 shot .. duh 45 - 50 hp
EMS is a must for all of this and you'll get about 10 - 15 from that


this is a very high estimate don't expect hits much unless you are god or have a 2JZ

 

indeed its a high estimate..you would not come even close to 8 hp with a cat-back let alone 15hp or 10hp with an intake or header.

 

how come no one has spoke on the stroker kit that came out? its only 3300 dollars and a 2.7L tc would be bad ___ . at least thats wat im gonna do. y does everyone have such negative stuff to say about someone wanting to go N/A. take a 300 hp N/A tc to a 300 hp boosted tc and see wat the outcome is.

Because going all natural cost a heck lot more money then just boosting. Shoot the technology that comes with boosting is a lot more efficient then going all natural. Primary foundation of power comes with how much combustion you can make. Turbo and S/C shove plenty of air into the engine to make more combustion. So thats why chargers are so efficient, they work directly at the source of power. Plus stoker kits wont get you 300whp off the bat..especially not by itself. You need to do a whole lot more like cams, polish ports, and etc. Estimated cost to go all natural is 30,000+

 

i did in my previous reply and the reason is because you could spend 20,000 to fully build your TC 2AZ FE NA and make 350. you could spend that much on BOOST and make 500 easy

 

you could spend that much on boost and make 700

 

well you would still have to build your motor to get that full power out of a turbo setup anyhow. i mean yea turbo would be so much easier cuz you have a boost controller and you can just adjust it to get that power but i think it would be cool to see a n/a tc wit 300 horses.
