i checked monkey wrench and i only seen ones for 03 and up. i founds sum crower cams on horsepowerfreaks.com tho. and yeah i know i also have a honda crx which is alot easier to find stuff for.

as far as internals go, any parts for a 03-07 corolla/matrix, 00-05 celica or mr2 spyder will fit our cars. just make sure the parts are for a 1zzfe and your good. also there was a compairison on the ninthgen forums about the valve size differences between the celica/mr2 vs the corolla/matrix heads. apparently the corolla/matrix 9th gen heads have smaller valves by 1mm. dont know if the same holds true with our heads, because i havent torn apart any of my spare engines to see, but will shortly. so i will mic the valves when i do.

really thats cool i didnt know toyotas were so interchangable but i guess it makes since bc hondas are the same way. ima have to look into gettin a celica intake manifold and throttle body somewhere. i should be ok with stage one cams shouldnt i? i mean as far as upgrading valve springs and stuff...
well they are almost the same engines. the 1zzfe-d was the jazzier version in some celicas and mr-2's. has a few extra hp and tq probably due to those valves and iirc a little different cam grind.
For cams, don't even bother with MWR Stage 1, unless you need to replace damaged OEM ones. There isn't that much difference between them and OEM. You could use the money for something else - like some sort of EMS system, especially if you want to get anywhere with your bolt ons.
Celica GT intake manifold and TB swap has been done on an 8th gen Corolla before - on the stock ECM - gains were minimal to none. Slightly more gains with a piggyback ECM - but still not a whole lot of gain there.
You'll probably get better gains by tuning the stuff you have. The OEM tune is very conservative - optimized for economy and longer service life. Pump the money into an EMS system (wideband, piggyback or standalone ECM, etc.) and see what the car is doing first. Then as you add mods, you make the appropriate changes to allow those mods to really shine - as the OEM ECM has a limited operation range for air/fuel maps, etc.

cam grinds seem to mic out the same to me. i have checked both the celica cams and corolla cams. there almost identical. as for the mwr stage 1. they do seem like a waste of time to me. if i wanted better cams for cheap, i would just have one of my spare intake cams repinned for the exhaust side and gain an instant 1.5mm lift and like 10deg duration. it would mean less bottom end but much better mid to top end. other than that the mwr stage 2 or 3 look nice.
one of the big differences is the intake manifold and throttle body. its shorter runners favor more top end power. our longer runners favor more bottom end. the reason we dont see as big of a gain as we should is because this manifold really starts making peak power right before our cars hit rev limiter. it would shine very well if we could go to 7k. which is not impossible. just need a standalone to do that. and even tho the 1zzfe is a long stroke engine, it have a very optimal 1.60:1 rod to stroke ratio. which means it should be a decent engine once freed from the factory ecu.
the celica/mr2 also have lighter casted rods, where as we have stronger and heavier forged rods. not a big difference but just means that we rev slightly slower due to more rotational mass.
ok cool im really learning alot here guys. my friend was also telling me i could get a thinner head gasket to make my compression higher basically only good for running an all motor setup which is what im doing. anybody have any input on that? hes a honda guy to so maybe thats something you can only do to them idk.

you can if you can find someone that makes one. another option is having the head shaved, but in my opinion if you have the head off, why not go ahead and drop some 11:1 cr pistons in there?

is it possible to remove the revlimiter by messing with the computer like the 7afe guys do when they go 7age? that'd be interesting

1zzfe celica has a 7k redline i think. i dunno, i have a 2zzge

yes, but its not as easy. there are 2 crystals that have to be changed. from my lurkings on many sites it seems that once its swapped you dont have a rev limiter. so it could get bad if you over rev.
7th gen 1zzfe redline is 6500-6600 if i remember correctly. while not much its still higher than the 6250 in the corolla. one guy on here said he had a 7k red line in a corolla, but hes in canada. it was fergifruitchew. i would like to see the part number on his ecu, because there are deffinatly difference between a us federal ecu and canada.
