What oil weight is used in this motor? Also I am using the stock water pump does anyone know of a lower radaitor hose that works well? and lastly does anyone have vacuum diagrams for the BT?

Thanks

anyone?

Google has the answer for #1 and #3. #2 depends on what cooling setup you're running and whether it is a fwd or rwd car.

I use 20/50. I was surprised that it should use such a heavy oil but that's what quite a few on here recommended.

I've personally always ran Honda synthetic blend 10w30 with Toyota "xxxF1" filter. Most people run thicker though. Are you using this engine in a RWD corolla? If so, you use the 16v RWD thermostat housing.
On the BT 20v I'm building right now:
-RWD 16v alternator and alternator bracket
-RWD 16v waterpump w/ 16v pulley
-RWD 16v T3 crank pulley
-RWD 16v thermostat housing w/ AE86 thermostat and AE86 outlet neck on thermostat housing
-The thermostat I have drilled four 1/8" holes in for cold start bypass
-JSP style mod to the 20v cylinder head. Coolant ports cut out and blocked off
-TRD 16v headgasket
-AE92 16v oil pump
-AE86 16v timing belt tensioner
-AE101 timing belt

I've converted the water system to 16v AE86 and the timing belt to AE101 style as the AE111 tensioner usually takes a dump and bends valves. People complain about doing 16v coolant flow direction on a 20v, I've been running it on several different engines for years, daily driven and tracked, never had a problem. All these parts I've listed can be bought right here in the USA from aftermarket or direct from any Toyota dealer. Tally up the cost of a new timing belt, tensioner, oil pump, and water pump for the 20v and this is about 1/4 the price.

I have a YouTube video devoted to the BT 20v vacuum routing. Search "DIY BT 20v vacuum routing". It will be the video by 'HASportAE86'.

I just saw the video. Thats works! as for the other stuff I'm running all 20v stuff but the alt. As I am currently rebuilding a forged 7a block for the 20v head. I want 20 4age 20v in with as little as I can put into it as I am putting the money into the other block

Anyone on a P/N or car to use the lower radaitor hose from? I doing a BT 20v AE86

You just use any lower radiator hose for the 16v Corolla GTS RWD 85-87. You need to use the RWD thermostat housing.

Thats not working as the 20v water pump comes out diffrently and I am not using the thrmostat housing from the 16v. I need a direct hose from the pump to the radaitor.
