installing 20V quads onto (in this case) a smallport 4age.. just to quickley point out.. the 20V quads WILL RUN ON THE STOCK 4AGE ECU.. and you should have no dramas running it like this as least untill you can afford a aftermarket ECU.. eg adaptronic.. but you will notice it use considerably more fuel.. as the TPS and MAP conflict with eachother.. and the vaccume to pull the fuel reg open isn't the greatest
Required items
Silvertop 20v quads, complete if you can..
Silvertop 20v TPS (hopefully you get it with the quads)
Manifold adaptor eg – tecnotoytuning (they make big and small port ones, price - $259 USD plus freight)
3mm vac hose (2m max)
5mm vac hose (2m max)
3mm t pieces/elbows
5mm t pieces/elbows
5-6mm barb fittings
inlet manifold gasket
JDM AE86 throttle cable?
Acess to a drill press/or a vace with a electric drill
Tap/die set
Small bit of sheet ally (to make a throttle cable bracket)
Hacksaw/file (to cut/shape ally bracket)
Steel cable, cable clamp from a bike shop (for accel cable)
1. remove fuel rail/manifold/tvis (if fitted) etc from the head
2. the manifold adaptor you have.. I’m going to use the T3 one for an example, the billet CNC machined adaptor, is a stunning manifold, I almost didn’t want to put it on it looks soo good! use a drill press tap 4 holes in the bottom of the manifold, 1 in each runner, infront/behind the 3mm ones.. NOT beside.. you might not be able to get to the studs if you put them beside them.. then tap thread into the ally for the barbs you have chosen, nice and easy in ally.. this is to link together with the 5mm vac hose to act as a balance tube (much smoother idle) and as a very strong vac for the brake booster.
3. The T3 one comes with 4 3mm fittings in each runner, as they are all separate I ran 3mm vac hose with elbows/t pieces linking them all up, and facing the firewall.. I used this to run the Map sensor as pic above
4. make a small right angle bracket with 2 holes that bolt into 2 of the throttle bodies.. I just cut a U shape and used the throttle cablenuts to tighten either side of it.. you’ll see the 2 holes I’m talking about.. there only small!
5. bolt the throttles to the manifold.. make sure all the vac hose is hooked up.. use zip ties as hose clamps


6. bolt the complete manifold on the head with the new gasket
7. I used my JDM throttle cable, having a 4AGE in there you should have a similar length cable.. I just pulled it through under the pedal to the correct length as it was about 6 inches too long and used a grubscrew cable clamp from a bike shop as the new end on the pedal.. just leave the bit of cable hanging around there.. I did.. ha ha
8. that’s about it.. fine tune the length of the cable on the car..
9. bolt on your injectors and rail to the head.. connect up the fuel lines..
10. plug in your booster line and map line
11. i had to rewire the 20V TPS in reverse so it would read properly like so
tps side > loom side
brown > yellow
Blue > red
Red > Blue
Yellow > brown
12. run one vac line to the fuel reg from one of the ITB's.
13. start her up.. see how she idles.. the individual idle screws I didn’t really touch.. nor the butterfly adjusment ones.. I just use throttle cable tension for idle speed (it's seriously not as bad as you think..) ..as long as you checked that they opened evenly on the bench.. adjust so they all move at the same time etc..
the stock 4AGE ecu will run them ok.. but it will run on the rich side.. i didn't test an SAFC, eventually i just went straight to a aftermarket ecu using only TPS vs RPM type tune.. which was great!
this is a quick video, running the stock ECU (in this case it was a AE82 twinky ecu/loom i used as i had a GZE in it befor this..)
