Need to know about 95-98 celica engines

my girlfriend of 3 years is buying her first 'new' car and shes going with a 95-98 toyota celica hatch, most likely gt. its my job to build it for the most part. i build nissan z32's and turbo 240's so i dont know most anything about toyota engines, so if anyone can help me it would be much appreciated.

first off i understand they come with either 1.8 or 2.2 (st v. gt) what are the engine codes for these engines?

4afe, 4age, 4agze... what are these engines out of and what are the differences? (heard them thrown around by friends with hachi's) from what i know the 4agze is super charged.. sounds nice (correct me on anything if im wrong)

3sfe, 3sge, 3sgte... what are these engines out of and what are the differences? are they from jdm celicas? and is the 3sgte from the all-trac turbo celica?

2zzge?? 20 valve?

of all these which is the best way to go, i like the sound of the 4agze, but i do like my turbos,, what is the availability of these engines, and which is the most cost efficent.. this doesnt have to be a drag car,, i just want it to keep up with my nissans.

if i left any engines out that i should be considering please let me know.

thanks for all your input.

well the st comes with the 7afe, a 1.8 with 115hp and the gt comes with a 5sfe with 135hp and 145tq

the 4 series engines are usually associated with the st as they are all compatible to be swapped in it. the 4afe is the 1.6 in the 90-93 st, and is a pretty weak engine with only 103hp. the 4age is the engine found in the older mr2s not sure on the hp numbers but the 20v(20 valve) 4age is a nice engine with 160hp and very light. the 4agze is a supercharged bversion of the 4age also found in older mr2s it has 140hp.

the 3sfe is a 115hp 2.0 found in the 4th gen celicas and is basically a piece of crap performance wise. the the 3sge was only used in america in the 4th gen gt-s and is a 135hp 2.0, it was also used in many jdm celicas in the 90s and the latest version is the 3sge beams with 220hp but was not released here. and the infamous 3sgte is an amazing engine. it is a turbocharged 2.0 found in celica alltrac/gt4s and mr2 turbos. the first gen 3sgte was 190hp, the 2nd gen was 200hp(225 for jdm) and the 3rd gen never released in the u.s. was 260hp. theese were found on the 4th 5th and 6th gen alltrac/gt4s respectivley.

the 2zzge is the 180hp 1.8 found in our 7th gen celicas gts versions and is equipped with vvtil(toyotas vtec). it is a pretty good motor but not as good as the 3sge/3sgte. there is also the 1zzge found in the 7th gen gt which is a 140hp 1.8.
and the 20v as i said b4 is the 20 valve 4age.

if u have a gt and are a skilled mechanic or know one the 3sgte is def. ur best bet. it can handle 400hp on stock internals at least, prolly more. and it has great potential.read the sticky section if u want more info on the 3sgte swap.

if u get an st your best bet will be 4agze or 20v 4age. theese are both good light motors and have their fair share of potential. 91celicast is building a pretty mean 4agze.

is it easier to swap these engines into the ST as apposed to the GT? also, iv seen (online) the 4agze put into the 90-93 (is that 4th gen?) celica with only minor modifications. is it the same way with the 95-98 celica or is it much more difficult?
the stock 2.2 5sfe in the GT, does it have a decent aftermarket, and can the engine itself hold much power, boost?
thanks

like i said the 4ag(Z)e is compatible with the st and not the gt, while the 3sg(T)e is compatible with the gt and not the st. the 90-93 is 5th gen. and swapping into a 94-99 is basically the samr as a 5th gen, they use the same engine for the gt version, both 5sfe.

the 5sfe is an ok engine its better than the 3sfe, 7afe, 4afe, and 1zzgte but not as good as the others. it is basically an econo engine with a low flowing head. the aftermarket is not too great for it, and boost wise you shouldnt run more than 8psi on stock internals just to be safe, maybe 10 tops. it can be a good engine, with stronger internals and a better head and more aggressive tuning. but as is it is basically a tuned down econo box. its sad that toyota would put an economy engine in something and call it a gt.

alright, so if she goes with the ST then my choices are really either the 20v 4AGE, or the super charged 4AGZE... while if she goes with the GT the only real choice is the turbo 3SGTE. right?
now,, when swaping these engines into their respectable cars do the trans match up? or is it a full engine/trans/harness/mafs/ecu/axel thing to do the full swap? now that i think of it, does toyota use mafs?
thanks for everything.

the trannies will match up but their strength is questionable. u will however need a new wiring harness and ecu. u could also swap a 3sge beams into a gt, thats what was used in the later gt's in japan.
