4afe to 4age: weight issue

[toyotaspeed90]

i don't know where you guys got your info that the 4a-ge was much heavier than the 4a-fe... and that it will cause the sedans and the sr5's to sit much lower on the front.... but you're way off

even though i have aftermarket springs and struts..... if anything (the only thing we removed was power steering and there wasn't a/c on either motor) the 4a-ge has the car sitting higher in the front now......

so if any of you think it's a problem it isn't.... i would have pictures to show (no, it's not running yet) but my camera got screwed up and somehow i lost the 13 pictures....

also, the 4a-ge i got was the heavier 7rib block smallport

[toyotaspeed90]

lol, nobody is going to admit they were the ones who said it???

i remember someone even said "go ahead and do the swap if you want to drag your oil pan across the ground"...

lol, on that note there's a large crossmember in the way for that to happen

so, next weekend we shall see if a tuned 4a-fe ecu and 4a-fe wiring harness (with some aftermarket goodies) can run a smallport

lol Toyotaspeed.. I believe I was in that debate as well saying that there was no difference in the engines' weight. Lots of misguided people here that get their facts from other misguided people, not from hands on see it with your own eyes knowledge.
Reminds me a lot of times when I was told things like, if you make your intake manifold from stainless steel it will get hot and break or melt.. Or that my little fuel pump that pushes 4-7psi takes 15-25amps.. and even after showing the person the specs on the manuf. website that stated a current draw of 1.6amp avg, they still didn't want to change there mind.. silly fucks.

I doubt that the 4age is lighter though.. It is just slightly heavier I believe, maybe by a 100lb's? If even.. that plus what year 4afe?

[toyotaspeed90]

i can't see there being a full 100lbs between the two engines.... the 4afe is a 90, and the 4a-ge is the slightly heavier 90 or 91...

as for accessories, there isn't any a/c (so that heavy ass idler pulley was pulled off), there isn't going to be power steering, so those brackets were pulled off.... we also found a "hunk" of rubber and metal mounted on the crossmember not attached to anything else... probably for removing some harmonic vibrations.... so we pulled it out (it's a good 5-10lbs)..... if i notice some huge difference i'll put it back in

but the power steering was pulled out as well... the heavy ass 4a-ge exhaust manifold was replaced with a 4-2-1 header (which is a bit lighter).....

so i would say i've made up for almost the weight difference... but it just looked like the fender gap was a bit taller than before.... (possibly because there aren't any fluids in the motor yet)

[|PuNiSh3R|]

fluids = like 5lb's if even?

*points fingers at xenon*

he looked into it and the information that he has gathered was that in order to drop in a 4age u need the gt-s suspension components....why that is, i am not sure. why this is so, i have no clue. but that's what he said

what do i know, i had a gt-s, i didnt have an sr-5!

[|PuNiSh3R|]

well, xenon might not be wrong.. seeing as toyotaspeed said he had aftermarket suspension on.. One thing I definitly know that you NEED better suspension for, or rip the suspension from the car is for an sr5 to 4AGZE swap.

[Dicipleofthelie]

how bout..well.....basic 4ac to 4age........will the suspension need to be changed with my car too?

[4Aaron GE]

I'm thinking the suspension difference might not be a 'hold the engine in place' issue, but rather a 'make it feel sporty in the corners' issue. Most of us overlooked the possibilty that the spring might have a higher rate, but also be slightly shorter as well.

[Dicipleofthelie]

thats probly most likely true......im thinking getting new struts and springs for my car.....a half inch lowering too

[|PuNiSh3R|]

The stock sr5 suspension would probably give a lot of over-steer with a 4ag in it..

[toyotaspeed90]

well, at this point if you're swapping a 4a-ge into an sr5 i HOPE you have done something to the suspension... it is getting to be 14 model years old (and that's for the newest sr5's! lol)

the control arms between the 2 are identical.... excep the gts has the mount for the swaybar endlinks.... the only main difference i know between the 2 cars suspension is that the GTS utilizes a swappable cartridge whereas with the sr5 you have to replace the entire strut......

i can't see the 2 having all that different of spring heights because since everything else is the same for mounts & whatnot, there could possibly be issues with trying to align the car....

also, most ae92 gts's that i've seen sit at the same height my car used to (when i had stock springs)..... i wouldn't be surprised if the GTS used a higher springrate though....

in either case, if you're spending the $1,000 or more that's required for this swap then you might as well change the springs and struts if you haven't already

[Xenon]

The front suspension on the SR5 is different from the GTS on the AE92's. When I bought my full TOKICO suspension for my SR5. I started installing the rears that went in like a hot knife through butter, but when I came to install the fronts, not only did I notice that the GTS came with shocks and inserts while the SR5 comes with a 1-piece strut. But that the height of the GTS shock is about 2-3" longer than the SR5 one, therefore it would not fit on my car.

That's why I made the assumption that since the suspension on the GTS is longer than the SR5's, there must be some weight difference issue considering that the two models sit at the same height!!

[toyotaspeed90]

as my journalism teacher says....

don't assume.... you could make an ass of u and me



sorry
if there's a weight issue, move the battery to the back... you'll be back to normal front end weight

but if you think about it... a strut height doesn't have anything to do with how high the car sits or the weight.... it's dependant on the springs..... if you take an oem strut and put a 3" cut stock spring the car will lower 3".... although that's a bad idea, just an example.... i've never compared a stock sr5 spring to a gts spring... if the strut is taller and the springs are the same, that would compress the strut more, causing it to be stiffer and give the gts a stiffer front suspension.....

on the contrary, it would push like a tractor
