NA or FI

[PPW-546]

i'm still in the dark as to what engine i'll be using for my 92.

my current 5AF motor is still ok but lacks, and i mean lacks, HP.

i still want to keep it streetable for daily use but it has a kick when you need it.

since the 20V is out of the question, i was planning to go for the high-horse motor.

but after riding with friends and driving an FI can, i suddenly became confused.


your inputs on the 4AGE high-horse and 4A-GZE motors would be appreciated.

thanks!

A 4AGE will never have the torque of the GZ. Get the GZ if you can afford it. HP/$ for high horsepower applications, FI wins everytime.

If you don't mind me asking why is a 20v out of the question.

[VooDoo]

period specific/correct issues.

he's obssesive-compulsive!

[Flashmn]

force induction all the way.

[digital_racer]

And I thought you were talking about Fuel Injection.

[micro214_kp61]

turbo the high horse... hahaha, lalo na na confused!

[PPW-546]

hahahahaha!

thanks for the input guys.

jason, i knew that you'd favor the GZE motor. hehehehe.

the reason why the 20V is out of the question is because I cannot bring out the full potential of the engine since traffic here is not so good plus i don't have long stretches of roads to play with. so i'd rather go for an NA motor with power from idle to mid or with an FI motor with power on demand, hence the GZE motor.

i'm leaning towards FI.

micro, your suggestion would come at a latter time. what i need to do first is to swap the motors.

thanks a lot guys!

there's a problem that everyone seems to be forgetting (or don't know) here.....

the 4agze doesn't come with a C series tranny..... do hard launches on a gze/c series combo and you'll start to ruin tranny's....

the E series tranny that comes with the gze's is MUCH heavier, uses a larger flywheel, and much heavier axles (mainly to hold the power just fine). On top of that, the E series is geared taller, and thus makes the gze 'slower'

also, the gze itself is heavier than a 4age... probably around 50lbs or so. You would be adding an additional 100+ lbs to the front of the car, and you will be changing the handling capabilities of the car.

from experience:

86 mr2: stock bigport 4age, stripped interior.... acceleration was ok, handling was really good

90 corolla: stock 4afe, modified suspension.... acceleration was terrible, handling was exceptional

90 corolla: fairly stock smallport 4age (same car as above), modified suspension.... acceleration is better than the 86 mr2, and handling was only made better by the power & smoothness of the motor

87 mr2: ae101 4agze, e51 tranny, trd japan clutch/PP, megasquirt ecu, modified suspension.... acceleration is enough to keep up with most V8 powered 'sports cars', handling compared to the 86 mr2 went WAY down....

(friends car) 89 mr2: stock bigport (suspiciously think it has a smallport shortblock though), stock tranny, stripped interior, race seats, cut springs, roll bar..... car handles about as good as the 90 corolla with 4age....


a lot of my experience tells me that in these cars... the extra weight added (unless it's with more than enough power to offset the weight.... and you need to distribute weight differently through the car anyways) will decrease the handling capability of the car.

so you need to ask yourself what you want with your vehicle before you choose an engine. My ae92 on a twisty road would dust my mr2, but has much less power and torque.... my aw11 would easily dust my ae92 on a straight away (even with the E series tranny).

go 20V!!!!! maybe with a little head work? you might find what your looking for?

just a suggestion...

i've seen a local 4AGZE'd corolla running with C-series trannys. holds up well during the drag meets back here. when i talked to the guy tuning the car and mentioned why settle with a C tranny and risk braking and axle during launches he mentioned that the tranny actuall holds up well. also, if in case an axle does snaps or the cv joints go, spare replacement parts are pretty easy and "cheap" compared to the stock E58 axles and cv joints.

[Flashmn]

C-trannies arent as weak as most think. Proper oil will go along way. Its the clutch thats gonna die.

[toyotaspeed90]

well.... i'll put it this way.... most guys using C series trannys in mr2's who are boosted keep 2 or 3 on hand..... because most mr2 guys HAVE had them break (even to the point where gear parts fly out of the bellhousings!)

[Flashmn]

Everything can be broken with overwhelming abuse.
