yes different plug on the ecu therefor different wiring. read on net that theres a 5hp? loss in power with auto ecu but whether thats true or not who knows. you can use either one with manual.. just wire it up correctly.

Ok next question...

if i get a t50 box will i need a custom bellhousing?

i didn't think i would but i just read a wanted to buy thread asking for one.

 

secondly differrences between 16v and 20v flywheel?

because i'm trying to source a clutch.. and flywheel.

 

also when i put my motor on the stand it went on upside down.

so the remaining oil still captured in the motor went into the rocker and from there into the

fual rail and into the throttle bodies..

do i have to dismantle and clean? or will it fire up no probs?

 

aslo it looks like you can't use FWD starter? true or false?

 

 

 

any help much appreciated

cheers,luc

ok did some more research..

sooo i can't use the FWD starter.

 

can't use my ke55 tailshaft...

 

i have a flywheel sourced but its a 200mm ish diameter.

 

what the deal with the 215mm ones?

I don't think oil mixing with the fuel and air going into your combustion chamber and igniting will be very healthy. Throttle bodies are easy to clean, not too sure on the fuel rails. Though it will more than likely blow a fair bit of blueish smoke for a while out the exhaust. If I were you, I'd clean it. But that is just me.

 

 

Next time, put the pin in the hole so the engine doesn't rotate 180 degrees boof head. Hehe.

can only use 4age bellhousing from ae86, at141 or aa63 for a t50. or ae70/ae85 k50 box which is not as strong.

 

the redtop16v smallport and silvertop 20v i believe have the 215mm flywheel and clutch. the s/t clutch i have here fits the t50

 

oil doesn't go into the fuel rail. theres separate air ports in the throttle bodies which attach to the pcv valve on the cam cover and also the fuel regulator, throttle stop, brake booster and iscv (idle speed control valve). requardless if they filled with oil, it's a good idea to clean them anyway as they're known to cause problem after alot of use as they slowly build up with gunk.

Any 4a bellhousing will work, but stick to a t50 with a 20valve for longevity. No point with the k box IMO. Your bell housing will be from any of the jap cars mentioned, or ADM ae71, ae86. ADM will be easiest to find.

 

The flywheels are identical in how they fit, but the difference is in the diameter of the friction surface. 200mm for bigport 16v, just like a 4ac had, so you can use a 4ac pressure plate and clutch disc with it if youre stuck. For this you need an Ae86 or ae82 twincam flywheel which is 200mm cause they came with the bigport. You have to use a 4a flywheel cause its 8 bolt not 6 like 4afe/4ac.

 

The larger flywheels are 212mm, and came with smallport onwards 4ages. They need a bigger clutch disc and pressure plate, so if you have a silvertop Id be looking for a 212mm flywheel and matching clutch. The silver and blacktop ones are lighter than most, about 7 and 6kg roughly.

 

What he said about the cleaning /\/\/\/\

ok thanks heaps for the info.

i have a jap t50 with the corresponding bellhousing.

i guess i will dismantle and clean the throttle bodies. rather annoying.

 

only way to learn i guess.

 

Toyoland has sourced me a 200mm flywheel.

the clutch to suit i believe is cheaper than getting a 212mm.

i'm keeping the motor completely stock so i reckon the 200mm and a h/duty clutch will do the trick!

 

thanks alot!
