using a fwd 4age what

1)gearbox options are there

2) flywheel clutch combo do i use

3) water/coolant relocation what do most people do

4) what sump is the go or am i beter off just modding the FWD sump

5) lastly not so much driveline related but do silvertop 20v itbs bolt up to 16v heads

thanks guys

1) T-50, or W58 with off the shelf adaptor/bell housing or whatever you decide you want to adapt, like a nascar 4 speed dog box. or be totally backwards and get a K-50, they bolt up.
2)200/212mm flywheel with stock or heavy duty clutch to suit ae86 corolla OR 9/5/3 ceramic clutch, metal twin plate, carbon/carbon twin. The exact clutch depends on your choice of Q1. Could even run a 225mm GZE flywheel and clutch if you chose W58 but these are heavy and there are better options, depending on money and power output.
3)Run the remote thermostat but point it forward from the back of the water pump to the bottom of the radiator or bolt on RWD cooling gear(not worth it IMO). Hook up the rest like normal. http://www.toymods.org.au/forums/tec...d-rwd-car.html Pictures are gone but the words still help.
4)Why are you modding the sump?
5)They don't "bolt up". They will however, bolt up to an adaptor plate that it bolted to the head. technotoytuning makes the adaptor.

What motor is it? big port/small port blue/red/red and black top? How much power are you hoping to make? It doesn't really matter but your questions are so vague. You could be making anywhere from like 50hp up to 450hp or something with a 4A which will change the answers a whole lot.

okay think that sorts out what box, what cars they comonly found in ? can a rwd corolla box be used eg ke70? likewise for the clutch is there a particular car i can use 1 from or does it have to be a billet or from a ae86 rwd

the sump will need modding to clear the front crossmember as i verry much doubt it will clear as is,

it is a stock as a rock 4age 100kw from a sx so i dare say small port. the fact that the quads go on is good as i can get a set again at a good price

to answer its going in a 1975 tx gemini coupe i can get a complete running 4age with manifolds and altonator loom for next to nothing like nothing nothing, i dont want to make mega power just depending what price i get parts for a 4age could be cheaper and make more power than building the standard g series

i cant answer all of your questions but the box comes out of the later te72's in the us it is 82+, the earlier 80's ones have a different output spline, but by the sounds of it your getting a custom driveshaft so any t50 should do as long as you have the ae86 gts bellhousing.
other options include the 1g bellhousing to w5* box. and there is an adapter that can be made to attach the lexus IS200 AZ6 to the ae86 bellhousing.

**Encyclopedia Ronnie** · 24-04-2012, 11:31 AM

yeah output slplines/tailshaft means nothing to me so long as i have the yoke thats all that matters really and that the gaerbox bolts to the motor properly lol, also i dont have a verry large trans tunnell so larger boxes like the supra box will be a verry tight fit and id rather stay away from

**Ken_T** · 24-04-2012, 10:16 PM

You want a t-50 out of an ae86 or ae71. The te72 gearbox will require a bell housing swap. There is a difference between jap and aus bell housings are different. Jap mounts the slave on the intake side where the aus ones put them on the exhaust side. No big deal though, just gotta get crafty with the clutch line.

You need the clutch for the engine if the engine still has the flywheel. Wouldn't hurt to meause that the friction surface is 212mm. You also need to get an ae86 throwout bearing. Clutch spline will be fine if you use the combination above.

I know it's probably not what you want to hear, but for all the work and money that will be involved putting the 4age into your gemini, upon your first drive you will be disappointed. sure you have a free motor, but as you know you will need to get a gearbox, custom tail shaft and may have to modify the sump along with other things, and the power will not be worth it in my opinion and you will start wanting to upgrade to a gze or turbo, yeah the quads will go on ----with the appropriate adaptor, but will require you to get an aftermarket ecu to have them work..

Have you considered just fitting the bigger motor from a rodeo, that's what everyone used to do.

sorry to be a downer,
Matty.

ive got 2 deo motors sitting on my floor i can ealsily build a full house g series engine but for the work it wont really beat a 4a with a set of cams quads and a standalone ecu ive got a microtech sitting here already so. im also not looking for big power just something a touch revier and overall efi reliable. otherwise there would be a turbo on my car already i want n/a simple as that lol

ken T, the slave cylinder dsnt mean shit to me i have to do a totally custom clutch setup anyhow as the car its goin in at current is a cable drivn clucth, the k-50 box u spoke of origonially thats from an early corolla yeas 5spd? im not trying to hold back big power so really dont care what box i use

**Ken_T** · 25-04-2012, 12:09 PM

4age isn't very fast but I prefer driving a 4age corolla to an NA SR silvia. They feel about the same but silvia is just boring to drive for some reason, probably because it's missing a turbo. lol.

FWIW I if I build a hack car it'll be an old rwd thing with a commodore v6 in it.

K-50 is cable buuuuut, it only came in AE85's and maybe jap AE70's. You can get one easy enough from new zealand but good luck finding one here. They're also integral bellhousing IIRC so, you can't just ship a bellhousing over with a locally sourced k-50 out of a KE55/KE70.

**Encyclopedia Ronnie** · 25-04-2012, 07:23 PM

ahhh okay so a aussie ke55/70 gearbox will not bolt up to a 4age

so basically its an ae86 or ae71 box or nothing what are they worth roughly?

for what its worth I HATE SR20s i own 1 too tho its in a gtir so that makes it a touch beter still shithouse engines, also any1 seen putting a comodore v6 in a gem should be swiftly shot, again it dsnt need to be fast but 4age's are a far beter n/a option than the sr20 unless u look at a vet but even then a 4age 20v blacktop will be beter

**Ken_T** · 25-04-2012, 10:01 PM

I dunno, I don't have a 4a anymore, they were like 150-250 for aus and more for a jap trans last I checked.

SR is fine. Barely has any inherent problems that need fixing but it's only like a few hours work to upgrade S13SR to S14SR spec. unlike CA18 which requires pulling the head off, and might as well fix the crank problem as well while you're fixing it.

There's a "crowd favorite" gemini here with a vn v6 in it. It's bunky as hell but pretty sweet.

Dude, 20v is only vvt, SR20VE is cam swapping with independently switching points for the two cams. Sure 20v has better intake ports but VE's VVL makes up for that stock for stock.

How much are you looking to spend???

There is now available an option to fit the J160 6 speed from the Altezza/IS200. It isn't cheap, but it is 6 well spaced gears.

The 4AGE can be made both powerful, and efficient, I'm making about 170hp, while maintaining over 30 mpg highway. I'm NOT using ITBs (not needed) and I'm running a 264 type (medium/mild) camshaft.
