project ae92 trueno hybrid

[rdyzz]

hello all this is the pic of my car with the trueno front.





the bumper is a kouki one. i just orderd a chargespeed lip for it. as of right now i need the kouki marker lights. the install is pretty easy. it took me a total of 1 hour to cut an modify things as needed. other than that the rest of the time was spent going back and forth getting supplys.

i got a cusco front strutbar coming and a set of cusco coilovers also. as of right now im going to work on refreshing the breaking system. i already replaced all the ball joints and tie rod ends. the bushing will also be refreshed.

the engine has some piston slap going on which will make it unreliable for the next racing season. so the plan is to rebuild it using some crower stage 1 cams hi-comp red top pistons and a trd headgasket. it will be managed by a greddy e-mange. compression should be about 11.3:1 with the trd gasket. im hoping the engine will reach a tune of 150hp. it should be a fun car for a momentum driving style.

i will not be installing any trueno rear bumpers as i think the us bumper macthes it okay. it is dropped with eibach springs right now, koni yellow up front and kyb in the rear. the handling is okay. its a bit soft for my likings. (NOTE. im used to the rough ride of my mr2)

this is how the 1" drop effected my suspension geometry. the control arms are close to being parallel. in this case since the springs are quite soft, when fully loaded the suspension geometry will be working against you in trying to maintain camber. instead your camber will become somewhat positive. i guess the only way to properly correct this is to either have someone custom make some LCA for your control arms. or stiffer springs, as it will allow the car to have less roll and thus keep alignment.

the bad thing about using LCA is trying to have custom ones make also for the tie rod end. since the tie rod is mounted in the back when the car is lowerd past the parallel point of the tie rods you will end up with toe out, this will may sound good; but its actually not. since the rod ends are also mounted top wise there will be almost no way to correct the geometry of it. you can't correct the control arm geometry without the tie rod geometry.

the rears on the ae92 is actually quite impressive due to the longet control arm links. due to it being longer height changes does not effect the geometry as much. this is also good in the sense that since it is longer when the suspension is loaded it maintains alignment better and ther is less of a change or the change is less significant.

(note. all this is just crap to adress how to better tune the car ultimately driving is about fun in that case just DRIVE)

Hey lemme know if you want to buy my kouki lights off me so you wouldn't have to modify anything. I have a set of 4 (clears and the yellows for the bumper) Ill make you a fair price

[melsae92]

hey i got the same bumper and im looking for a lip how does the chargespeed lip look like and how much is it?????

[rdyzz]

not sure about the looks. i was actually not even sure chargespeed even made one for the kouki trueno. i know of a levin zenki and kouki lip and a zenki trueno, but not the kouki. so this shop i called contacted chagespeed and so claims they have a kouki lip for the ae92 trueno. my guess is it will look somewhat like the levin lips as the bumper is similar. i should get it in 1 month. i'll post pics then. price is $330 shipped.

um.... my ae92 on ST springs (which are generally soft) have negative camber.....

[freakinbox]

I actually like it better without the kouki marker lights (I hate them)

[sportrally88]

are the kouki marker lights the big 1's............if so keep what ya got! they are friggin horrible

[freakinbox]

yea, alot of us hare the kouki lights. They are way to big for the front of that car

[TheOtherCarolla]

Looks good. I love the "stock performance" look.

im not talking about the set (standing) alignment. i'm talking about what happens to it when things start moving. such as when the control arms move upwards due to suspension compression.

sorry if i come out sounding like a a$$, i don't mean to im just a suspension geek.

[rdyzz]

all plans are.

breaking-
refreshed braking system. sports pads (porterfeld r4-s, greddy) maybe slotted rotors? reman calipers, that or i'll rebuild it. ss lines.

suspension-
cusco coilovers 7k fr 5k rr, fensport bushing kit. im debating on the sways right now as they make the suspension less independent.

chassis-
cusco strut tower brace. maybe JIC lower brace. there isn't much here to adress. i don't feel like having a cage or pouring urthane foam in the frame.

wheel/tires
15X7 rota j-mag (didn't realize they were the mugen knock offs untill after i orderd them) maybe azenis rt-615 205/50/15 i want to try somthing different.

engine-
crower stage 1 cams, redtop high comp pistons 10.3:1. trd head gasket claims it ups the comp ration 1 whole point. rebuild. maybe cam gears, maybe greddy emage.

tranny-
nothing yet this winter. future plan consits of new syncros, and a helical lsd.

this is pretty light tune, but will give even sti's a run for their money at the autocrosses.

this has always been a car i've wanted to build. since my mr2 is practically done.

yeah, but i'm not sure your analysis is accurate..... the easiest way to prove what you're saying is to tell you to go lift your car up......

lift the wheels off the ground..... the control arms will move down.... by the way you're describing they should cause the wheel to get negative camber... but that's 100% inaccurate.... they will go relativey positive.... put the car down, the wheels will stay a little positive until you drive it around.... and it will have neutral or a little negative camber

vehicles aren't designed so that when a strut compresses the tires go positive..... if that were the case there would be a LOT more rollover accidents...... and also ae92's wouldn't be allowed to auto-x, as positive camber isn't allowed

I like both Zenki AND Kouki.. I think the Zenki is sexier, but the Kouki still beats having the ugly ass north american front.

if the control arm is at its longest arch parallel/stright. then it can only get shorther and thus pull the bottom of the spnidle in as it compress. i've done this test on a laser alignment machine to test camber changes with load. both camber and toe changes with load. so i'd imagine in the case of hard cornering where the car will be rolling and the suspension fully loaded your camber will be affected.


im talking about a lowerd suspension. say you set your camber to -2.0 when it compress and your control arm is already stright and at its longest point. say it compresses. that will cause the control arm to move upwards making it shorter. making that -2.0 into maybe a -1.7.
