Blactop 20v engine ($1200 - 1500)
-With or without harness depending on wiring decisions
-With all sensors, distributor, coil, and igniter
-Did I mention all sensors; O2, IAT, TPS, MAP, etc.
Wiring (cheap - $550)
-Make custom using 20v harness
-Have somewhere like Tweak'd Performance make you a new plug and play harness ($550)
Convert cooling system one of these ways: ($50 - $690)
-Convert to 16v flow by making a custom kit ($50-100)
-Convert to 16v flow using Sam-Q's kit which can be bought through Battle Garage or similar ($355 + source some hoses)
-Retain 20v flow using a water line kit from T3 ($690) or SP-Tech (If available $550) (Don't do this - See later water kit install post for explanation)
Distributor Issue (free-$550)
-Hammer firewall or cut and weld a box in it for the distributor to fit (free)
-Buy a relocation kit from Sam-Q or similar ($550)
-Run a waste spark system which you can wire in or have Tweak'd do for you. This allows you to run coil packs from a newer Toyota on the stock blacktop ECU. I am using 1zz COP's from a 2008 Corolla. Note you will still need your coil and ignitor for the signals.
(wiring from tweak'd $50) (coil packs $180-300) (Dist cover $90 at Battle Garage or make your own)
Some purists don't think a waste spark is proper, but many have run it with no problems. In my opinion it is a clean and cheap solution to the distributor issue. Plus it's just cool.
Fuel Line (free - $90)
-Make one using one half of your 16v fuel line and the other half of your 20v fuel line.
-Get Earl's fittings and stainless hose. Summit Racing had everything: two -6an banjo fittings, 3ft of -6an SS hose, and a fuel pressure gauge that mounts into the top of the fuel filter ($90) Here are the part numbers for all the fuel line parts needed:
Other Stuff (some optional)
-OEM 20v gasket kit ($250)
-Timing belt ($38-100) Hydraulic tensioner ($74 from Battle Garage) Tensioner pulley ($78) I used an OEM belt, tensioner and pulley. It is crucial to replace these parts as the blcktop is an interference engine. Many people convert to a 16v pulley, but this requires a 16v oil pump, water pump, etc. I figure the engine came stock with the hydraulic set up so it should be fine.
-OEM 16v Pilot bearing and throwout bearing ($30-50)
-Clutch kit of some kind ($90-300)
-Engine mounts ($100) if needed. I used OEM mounts for more vibration dampening
-Transmission mount ($80) if needed. I used a Cusco mount for more stiffness on the driveshaft
-Rear Main Seal (Might as well do it while you're in there) ($20)
-Electric fan set up, unless you run a 16v style water kit. The 20v waterpump isn't strong enough to support a clutch fan and is known to break. ($50-100) Tweak'd performance wired in a relay for me that runs off of the stock coolant temp sensor.
-O2 sensor. use either the 20v one or an o2 from a 1993 mr2 non-turbo will work too) ($60-100)
-Coolant Toyota Red coolant is best ($28)
-Transmission Fluid Redline mT-90 is what i use ($30)
-Engine Oil and Filter ($25-60)
-Fuel filter ($25)
-Coil on plug plate (custom =cheap) (Performance Options has one for about $90)
-A couple custom mounts for the IAC valve and the MAP (free - $30)
