Forgive me if this topic is posted elswhere. What power potential does our 2.4 TC motor have "all motor". I know being a toyota it can handle a good bit of stress, but what about good ole clean hp/tq? I have a respectable ride whith Just intake/header/exhaust, but need more!! :P I want to avoid the supercharging/turbocharging route (at least till the money comes thru)

Nobody really knows yet, there isnt any dyno sheets of parts that are out there.

-Ported Head
-High Compression Pistons etc.

well 200 whp thats for sure but thats with a head high comp pistons breather mods and a pulley

It will cost you a lot more to get to 200whp NA than to get 200whp with FI

couldnt have said it better myself. for the same money as 200whp n/a, you'd probably get more like 250whp with forced induction.

True but if you get stock compression pistons that are forged and get a p&p head with all the bolt ons then the turbo kit will make a lot more power. I think the stage 0 zpi kit makes 230 whp on a stock tc, but when you get exhaust, p&p head you should gain 20hp easy. It all depends on what you want. I am building mine for n/a now but I may turbo later on and so far the only wasted money is on the header and cai, I can use all the other mods with the turbo kit and yeild a higher gain then would on a stock tc.

i guess it just depends on what kind of fast you want. i presonally think its more fun to drive a 13 second n/a car than a 13 second boosted car. the engine is more raucous and it just seems like a more "violent" type of power. boosted motors are fun too though, and there nothing like a hard hitting bov to make everyone envious. i guess if it was my money i'd do the turbo, but n/a is a good idea too. just make sure you know exactly what u want b4 u drop any big bucks. i had a tiburon a few years ago and bought a turbo manifold, bov, wastegate and a few other things and ended up going n/a... bigggg mistake!

sorry, i just re-read the thread and realized i am getting way off topic. apologies to all moderators out there.

It will cost about 8 grand to get the tC to 250 WHP Naturally aspirated.

After doing so. Your car is not street legal either (at least not in california)

P&P + Valve work
Golden Eagle sleeved and bored block
Golden eagle NA cams
11:1 compression piston heads
Pully
I/H/E
Larger injectors
Computer + tuning
Flywheel
and the labor to get'er done.

decals and fart cans do wonders.

Well the benefit of living in the south is that we dont have the strict emmision standards as Cali! (LOL, i mean we got half rusted no exhaust sporting camaroes runnin around here) I guess my main goal is to have the local honda boys wondering what silver blur just flew by. I can hold my own right now. A turbo/supercharger is going to happen later on, i just want to get noticed being NA. Keep up the suggestions guys!!

I find great joy in having a car faster than most of the daily honda boys before my upgrades, and catching up to the higher end guys peice by peice. When I was in high school, and even still today, nothing bugs me more than that vtec weed wacker noise

LOL, i know what you mean. I used to be one of those Honda boys back in school. So has anyone found out what the 2.4 can handle stock? (with all internals and such) Is it built like the GM ECOTEC? (had one of those too!! lol)

dont you love people that respond and contribute nothing usefull kind of like this

I've had just about every type of car out there. bored out z28, wrx sti, prelude, even had a Big Body 95 Impala SS.

one thing i've learned is that no matter how fast you are, there's always someone faster, so the best thing to do is to ask yourself where you will be comfortable. what will it take to make you happy?

to beat the honda boys?
to have bragging rights?
to just have a fast car?
to go ballz to the wall speed demon?

once you can answer that, then you'll know if u need to go blown or stroked...hell, maybe even BOTH :)

The answer will always be... "depends on your pocketbook."

The big problem with the 2.4 is the FE head. Pick up any old 2AZ head from any somewhat-recent 4-cylinder camry (the 2.2L one is fine) and get someone to port it. Do a head swap, and this with your basic boltons should get you about 175+ whp in NA form.... and you'd probably be the first.

Also... I'd keep in mind your future goal at all times. I'm going N/A, but other than an intake (and possibly pulley),I want to be able to keep my current mods when I slap the S/C on it.

Will that work? (taking the old camry head and port/polish) As for the "speed" question, id say a combo of all the above. Braging rights help!! But as mentioned before, there will always be a faster car. LOL

According to a friend of mine who is a scion tech, yup.

Has anybody with a street tC done their internals, like extensive work i mean? if so what have their results thusfar been? :question:

Not to bring up the honda stuff again, but thats just like swapping the heads of different B-series motors! LOL All i would need to do that is find another 2az head and go to work?

Well... it's not anything like swapping heads on a honda... since you're putting an identical 2AZ head back on, just after you've ported it.

It's comparable to taking off the head you have now, porting it, and sticking it back on.... just without the down time.


But to answer your question... yes. Any 2AZ head should work, even ones from the 2.2L version. The .2 litre difference comes from the bottom end, perhaps different rods or pistons.

Just a quick question...Is the size of the CC on the 2.2L version of the 2AZ head the same as its larger (2.4L im guessing?) head?If it is smaller would the smaller CC size give a higher static compression ratio? Just curious. thanks

Actually it could be either more or less compression. Honda guys have this same dilemma because of different pistons/heads from different years have slightly different dimensions. My real question is that I think there never was a 2.2l 2az... Actually there was a 2.0l 1az and a 2.4l 2az (looked it up on this site http://en.wikipedia.org/wiki/List_of_Toyota_engines). If there really was one then now we could possible de-stroke our engines, have different pistons to possible use, or even the head could possibly have a smaller or bigger combustion chamber (which would change the compression ratio).

I also found this link (http://en.wikipedia.org/wiki/Toyota_AZ_engine) it shows some differences of the AZ family of engines. I am interested in the pistons of the 2az-fxe engine... for the NA guys 12.5:1 compression is even higher then what ZPI is offering right now. Maybe someone should try and obtain these pistons from a junk hybrid. It would be really interesting to see if the benefits if this could be done.

Now thats what im talkin about OuterHeaven!!! Just like Honda's Engineers (LOL not to bring up the honda again), they placed several performance parts thruout many B-series engines as well as many year models. "Frankenstein" engines! Any kind of gain from just "swapping" parts is great in my book!!
