Bang 4 Buck mods for '90 Seca SX
|
Wed, 25 September 2002 07:32

 |
Hi guys, I have a budget of around $1000 to do some mods to my 100KW 4AGE. I currently have 1990 Toyota Corolla Seca SX. I am basically wanting the best bang for my buck. I have just found this website yesterday and found it extremely helpful, but I haven't found anything cement for what I'm looking for.
I am looking at any of the following options, and some combinations:
* Cold Air induction/Filter/rampod
* plug in chip - powerchip/chiptorque...
* aftermarket ECU - autronic/Wolf/Microtech/motec, etc...
* 4AGE 20V motor conversion
* 20v throttle body?
I haven't put an exhaust in there yet, as I don't necessarily think it will be a cost effective mod stand alone, but am open to input.
Thanks guys

um, you'll need a little more than $1k for a ZE, quad t/b or ECU conversions.
try the usual route, exhaust, intake. get it breathing right.
if thats not good enough try some longer duration cams with a little bit more lift?

Powerchip quote $890 for their plug in chip. It gives 8KW with use of PULP and 11KW with use of 98ron only (they are 2 separate chips though). They say they modify the standard program to suit if you have cold air induction and/or exhaust.
BTW when I said budget of around $1000, I was being fairly conservative. I could quite easily spend up to $1500, the problem is, the moment you say $1500, you end up spending $2000 and so on, I'm sure a lot of you can relate to this... 
The other thing is, I don't really want any more power than 120KW (at the flywheel). So maybe I should be asking, how much would I have to spend to get this much power, and what would be the best way to do it?

Yep, they are AE93. I can confirm that coz it says so on my SX Seca
Tanman, what configuration were your extractors? 4-2-1 (??) and in what range did they make the most improvements?

Gday,
I dumped a 20 valve 4age into my ae92 sx seca. Very impressed and very happy.
ECU/GEARBOX/ENGINE for $1600.
WIRING help - $300.
Catcha,
Seeks.

Seeks, do you need a different gearbox for the 20V? did you sell off your 16V? if so how much?
How long did the conversion take?
Have you had your car dynoed? I'm wanting to hit somewhere between 110KW and 120KW at the flywheel.
Thanks - Craig

I would like more than 120KW, I just don't want more than 120 going through a FWD corolla. I'd rather just buy another Liberty RS (which I don't want to do just now) - now that baby could move 
BTW, nice pics troyboy - mine is white too...
seeks, could email me, would like to talk about your 20V conversion - still haven't written this off, but is looking a less likely option by the day...

Gday all,
"please dont waste ur money on a 20V
they will always be in my exhaust fumes.. (riiiiiiiiiiiight)
save ur money... if ur driving in traffic.. gze...
if ur on a track.. apparently the 20V
lets face it.. how often are u on the track."
Troyboy you crack me up, i knew as soon as i wrote '20v' some nay sayer would kick in. Gotta love this type of comment. Man I love revving the piss out of my smooth engine, it's great, i've been in a 4agze and wouldn't dream of getting one instead of the 20v.. I'm 'on the track' as soon as I hit the road, and in the 20v, I feel like i'm on the track too. Why the hell would you want a gze in traffic, to use more fuel ? pay more insurance ? accelerate faster to 15km/hr before having to slow down behind the person in front ? choice!
If you're in traffic, go replace your engine with a 4ac  .
Troyboy, drive your 4agze and enjoy it for what it is, I reckon it would be fun too! Personally i like 4agze's too, but don't try to convince people a 20 valve is a waste of money, because you're wrong.
Cjeff, if you like the idea of having a 20v in your engine bay and being able to happily flog it to 8000rpm while listening to the quad throttle bodies sucking it back, go get a 20v and be happy that you have one of the smoothest fastest 1.6litre normally aspirated engines ever released in stock trim.. I did months ago, and i'm still happy. If you want forced induction, go get a gze. (or do it properly and get a 20v turbo)
Catchas!
Seeks.

Gday cjeff in reply to your questions,
"

"
I used the 20v gearbox. I'm not sure if the 16v gearbox and the 20v gearbox are interchangable without any modification.
Putting the actual engine in only took a couple of days, wiring slowed me up, it took a month, but i was doing it on a student budget and had to do a chunk of the wiring myself while juggling exams etc. I had a big thread going on here the whole time i did it, everyone was very helpful, i'll try to find a link to the thread if you're interested.
I havn't had it dynoed, i'd say it is probably about 105 at the flywheel. Thats with factory airbox, standard small exhaust etc. If u got exhaust and better induction it would make a fair difference, the standard 20v extractors are meant to be quite good already. Use good fuel, it makes a noticeable difference too.
Thanks,
Seeks.

Well Seeks,
I may go the 20v into my AZ92. It currently has a 4A-FC with a shitter 3spd Auto. After this Auto was installed I cannot rev high in first gear without one hell of a gear change 
I am hanging out for revs, and the ability to SHIFT the gears myself.
What modifications did you need to do to get the 20v engine into your engine bay? Which mounts did you use, radiator? (I've heard the 4AFC radiator is perfect for 20v.
The wiring is what worries me, as the car is currently carby... I am picking up the complete wiring system book for my car next week from Holden so that should help.
Is there any torque steer with the 20v?
Finally, did you solve your starter motor probs?

All 'A' series gearboxes are interchangeable, that's why they're call 'A' series. For High Torque, force induction, use the ZE, but are absoultely crap for N/A use. For nice close ratio's the 20V boxes are are the best. The standard boxes found here will cope behind a ZE, and handle a 20V no worries, but no LSD...

Further to my previous questions.
Do you guys with 20v's have the aircon attached and working?

I gave the Air con the flick, the engine was intended for racing. If you get a whole front cut, everything is there, it's just a matter of transferring and hooking it up, otherwise a bit of thought, you could use the factory fitted stuff the car came with.

Gday inertia,
"I am hanging out for revs, and the ability to SHIFT the gears myself." - hehehe, if it's revving you want 20v is the go!
"What modifications did you need to do to get the 20v engine into your engine bay? Which mounts did you use, radiator? (I've heard the 4AFC radiator is perfect for 20v. " -
I believe that the 4ac radiator is the way to go as my 4age radiator actually needed some very awkward piping. The engine just fits, I didn't need any mods. I don't know what your fuel system in your car is like, but i do remember people having to change the fuel pump workings when moving from carby to injected. The SX ae92 fuel pump is actually built into the tank, it doesn't sit in the engine bay, you might wanna check out your fuel pump and stuff before going further.
"The wiring is what worries me, as the car is currently carby... I am picking up the complete wiring system book for my car next week from Holden so that should help." -
The wiring also worried me, Grant from sixworks helped me by doing some of it, unfortunately i had gone ahead already and chopped/butchered some of the harness so i was on my own for a little while too. All in all, if you have the books, the right ecu/plugs and the wires, it's all just a matter of sitting down and planning things out. Oh, also a soldering iron and a multimeter can help at times too , and a spare car to drive around and... hehehe
"Is there any torque steer with the 20v?" -
yup, it's not that bad though, just hold the steering wheel tight. I've had people drive my car and been really turned off by the torque steer, but i hardly even notice it.
"Finally, did you solve your starter motor probs? " -
Yup, in my engine conversion i lost the battery brace so what happened was the make shift brace i used came undone. The battery slipped, pulled out an earth wire. Then a much smaller earth burnt through and snapped due to having too bigger job for such a small wire. All i had to do was re-wire up some better earths and get a stronger/better fitting battery brace so the damn thing didn't move again .
Have fun!
Seeks.

i like ur avatar!
u know what.. ask Daniel (djb23_20v)...
he had a 20V in a seca ae82
now he has a GZE in a seca ae93
ask him.. i guess hed be the best person to ask as he has had both and done both conversions...

Guys,
I put a 20v in my (lighter) ae82, and shes really got along nicely. 20 is really smooth and revs out cleanly to redline, lots of fun to drive. But, to really get anywhere you had to rev it to bits all the time, which really isn't good for it (even though its Toyota-Tonka-Tough).
I just finished a 4AGZE into AE92, and it walks all over 20v, even with the extra 100kg of car for the newer model. GZE has so much torque from idle, unlike 20v which really needs to wind up to 4500rpm before things start to happen. GZE doesn't need to be wrung to redline either, you can just massage the throttle to shoot along in traffic. And GZE is heaps easy to boost up with a pulley kit, better intercooler and free flow exhaust.
Conversion wise the wiring and the labour is roughly the same amount of work. I ran the standard g/box with my 20v (but that died a horrible death after a driveshaft shop didn't tighten up the driveshaft flange and the driveshaft work loose and ate the g/box casing just after handing in my final year mech engineering thesis). With the gze I've fitted the GZE g/box, driveshafts, struts etc.
So thats it, I vote GZE.

Oz_Craig,
I believe you are right when you say it doesn't feel like twice the Kw. Prolly because it doesn't have twice the Nm as the 4AFC.
The ole 4AFC has 90HP@5500 and 135Nm@3600 from memory. The AE92 GZE has in excess of 200Nm and this is what we feel pushing us back into the seat.
I have yet to be in a 20valve, but Fassil was nice enough to take me for a spin 'round the block in his GZE and it was awesome!
Anyone in Melb got a 20v AE92?
Oh, and where are the 20v video's?

Well guys, I've decided against the engine conversion for my bang for bucks. This is what I've come with so far...
I'm going for the exhaust and the Cold air. But this what I have questions about...
My friend has a stuffed 20V lying around with the original extractors and the quad throttle body. Are the 20V extractors any better than the 16V's extractors? If I custom fit a quad throttle body to the 16V, what will need to be done to tune it properly? More importantly how much benefit, and how much to get it sorted?
If I fit my mate's extractors, I can get cold air and 2" exhaust for $700. Powerchip sell their chip for $890 - has anyone had one - did it make any difference?

hey guys, im getting a 100kw worked at the moment, nothing serious... a head job  and 20 thou over pistons, balanced, and lightened flywheel, havent put it together yet, cant wait, its going into a ae82 seca but i tell you what, the old 86 kw sometimes surprises me.....its stock with hurricane 2" extractors 4/2/1, 2 1/4 stainless exhaust and uni filter, shes getting a little tired but still a little rocket, also ive been trying to find quad throttle bodies for the 100kw, no luck other than new at $1500..rightttttt

Just remember you will be paying a couple of thousands extra on insurance with a gze compared to a 20 valve.
