OK so my T18 so far has cost me -
Around $1000 for a very good shell (sold off engine T series diff and few other bits originally was 2k when I first bought it)
The diff I have built my self ended up costing just under 1k (including disc brakes) It is a hilux G series
Diff - $400
Rotors - $150
Calipers - $150
Caliper brackets - $60
Plus the time it took me to cut all the mounts of an old diff I got for free, clean them up and weld them all on, and still need to make a tailshaft and get it balanced.
Engine ended costing me absolutely nothing! $0, FREE! But it took 2 months to get the money back for it as I bought a whole Lexus LS400 with a 4L 1uzfe for $1200 then pulled the engine out and sold off every thing else cheap so got a free engine.
Then I decided to get a good gearbox setup, which consits of a Richmond close ratio and 1:1 5th gear 5 speed box with custom bell housing, flywheel and 2 clutches 1 from a nascar the other from a V8 supercar,
This all cost 2.5K though so not cheap but because the engine ended up costing me nothing I didn't mind.
Then the suspension -
Coilovers and rear shocks - $1300
Front brakes - $700 (T3 wilwood setup)
bigger swaybars - $200
So there is 2k there as well.
Fuel setup -
Tank from work from a yaris $Not sure yet ill see how much
Fuel cell foam $not much maybe $50
Surge tank, lift pump and fuel pump $200
Roll cage - about 1.5k
Then there was about another 1K in other little bits and pieces.
