6G Celicas Forums

recently ive been looking into buying parts for my 4th gen before i put it back in my coupe and i got the wondering to what are the most important things most people replace before you put in a motor.

With the help of lagos and pitcelica, i was given some useful info and advice that would help us all should you go down the road of a swap.

The following are things reccomended you replace before putting motor in, and in a 4th gen owners case, a means to get your hands on the parts!

Stuff that was suggested:

-rear main seal : even if the part numbers are a little different than gen2 or gen3 3SGTE, I'm 99% sure that they are all the same seal because the crankshaft is the same on all gens.
-front main seal : gen2, gen3 and gen 4 have all the same part number.
-cam seals : gen2, gen3 and gen4 all use the same exhaust camshaft and both cam seals (intake and exhaust) have the same part number, so, by analogy, any 3SGTE cam seals will do the job.
-thermostat : a gen3 thermostat will work
-waterpump : a gen3 waterpump will work

belts are the same across generations so u can go to napa or something to grab one (I would personally reccomend you get an OEM toyota timing belt, and any other part you can b/c of better quality lagos can hook all 6gc members up thru toyota )

I would add timing belt, timing belt tensioner + idler pulley and all brand new v-belts. Verify if the coolant hoses near the oil cooler are in good shape. Do not change them if they aren't worn.

I used toyodiy for comparing the part numbers :

'01 Caldina : http://www.toyodiy.com/parts/g_J_2001_TOYO...215W-DWMZZ.html
'95 ST205 : http://www.toyodiy.com/parts/g_J_1995_TOYO...T205-BLMVZ.html
'94 MR2 : http://www.toyodiy.com/parts/g_U_1994_TOYO...L-AJMZZA_1.html

Good luck!

and for good measure, i found this old list from somewhere on this site that was listed about interchangeable parts throughout the gens of 3sgte:




The alternator can be replaced with one from any 5SFE or 3SGTE, along with the a/c compressor and the p/s pump (though the 4th gen p/s pump uses an electronic sending unit for the idle-up).

Bear in mind that the 4th gen injectors are also high-impedance, and no resistor pack is used.
-pistons
-connecting rods
-crankshaft
-exhaust camshaft
-cam gears
-timing belt
-water pump
-Intake manifold (bolt pattern are the same)
-fuel rail and injectors from ST215 are 540cc and top feed, so they have the same output rating as gen3, but they are top feed instead of side-feed(gen3)
-exhaust manifold (same bolt pattern)(but the 4th gen exhaust manifold is casted with the turbine housing)
-MAT sensor (manifold air temp)
-MAP sensor
-crank pulley
-oil pans
-oil pickup system
-knock sensor
-ac compressor
-alternator (5sfe as well)


EDIT: i recently found out that the timing belt you would get from a toyota dealership would be different this means that the gen 2 3s (usdm) timing belt would be off by one tooth. if thats no big deal to you go for it!

must have been a complete nutz....but what mods are needed for the axles east? can you explain if any is needed to mod or are the axles off st215 perfect fit? or are there any interchangeable axles among the toyota family for the tranny...well i guess it all depends on the tranny. what would you recommend?

lol its ok bro, no changes are necessary for the st215 swap. that motor is bascially the same as the other gens. other minor differences will need modification (ex: cams) but axles can be used from a GT celica and the trans from a V6 solara,Turbo MR2 or the most common, a camry (s54)


i have some pics (i think?) of the axles going in, they are the same will go in without any more trouble than normal.

i serioiusly doubt the axles from a caldina will fit (because is an all wheel drive car)

to clarify, i would still need differ inners depending on the tranny whether it's a mr2, solara, camry, or my reg gt tranny...and the outer would be what exactly?

you ONLY need the mr2 inners, and alltrac outters if your using the E153.

the S54 uses the stock axles.

as far as the parts are concerned, i neglected to be specific (thanx chacha )

as reccommended change the parts mentioned before, but to make it easier, here are the part numbers of the things that will fit on the 4 gen, when refreshing your motor


i dont have the part numbers of the rear main seal ($26.26) and front (crank) main seal ($10.00) off hand but they ARE the same as the other gens, and can be found in the parts thread made by our good buddy lagos!
(remember to call coniceli toyota and have part numbers, not a clusterfcuk like i gave lagos lolz)


Cam seal-903111-35022-14.90

timing belt-13568-79045 $26.49 BE CAREFUL.... this timing belt is likely from a 2nd gen (usdm) will be off by 1 tooth

thermostat-- apparently the 4th gen thermostat is slightly larger so tweak informed me that one can use a thermostat from a 4 runner 98-2000s iirc.

H20 pump-16100-79127 (GEN II) 16100-79127-$102

H20 pump (Gen III) 16100-79126

NOTE: These two parts are off by one number, but i believe they are the same


all of your accessory (aka V belts) are the same as the other gens.

Idler pulleys 13505-88383-$88.42
13503-63011-$41.69

sorry if this is a bit thrown together, i just wanted to get the info out there before i went to work, any questions shoot!


EDIT:
from what i understand the head gaskets are the same as well. im 99.9% certain of it

found some extra info for anybody curious about the 4th gen....



study to show thyself approved!

http://www.alltrac.net/phpBB2/viewtopic.ph...71&start=30

Thought i would update this thread, i totally forgot to add information about the RODS of the 4th gen engine. the rods in the 4th gen are DEFINATELY THE WEAK POINT OF THIS ENGINE. In my attempt to correct this problem, i got some REALLY good info about 4thgen versus 3rd gen rods

thanks guys!


read up!

Oh! Ask cuts or someone in australia. Maybe even 3way stunna. Hes in japan... But idk if it will be in english! I have some big ass parts list for the caldina but idk where it is on my comp

it need to be the st185 outter , not the st205, they wont clip[

We actually used ST165 outters, and they work as well.

was also intrested in this swap can you elaborate on the minor differences(ex: cams) that needed modifications for your swap?

peace

hey bro, the differences are minor, the cams on a fourth gen have a notch on the end where it fits into a slot for somthing... i cant remember at the time.... also the rods are from a beams motor and are skinnier than the other generations. he motor is a high compression which means quick spool, but be careful with boost. not much needs to be modified to be honest with you if youre doing a basic swap. its just about the same as other gens in this aspect. it has no spark plug wires, and puts out a bit more hp than the 3rd gen, and is a newer motor, but to be honest, if you want high horsepower get a 3rd gen

thanks for the info. yeah seems the 4th gen is a little better option for me as i'm looking for an alternate replacement option rather than a platform to mod. and they can be sources much more cheaply
