[bhansen42]

87 Supra Turbo
108k
no snow
no salt
stored winters
body good
seats bad, needs seats: ching ching ching ,any suggestions?
probable water pump failure :ching ching ching
coolant leaks around head, bhg? :ching ching ching
coolant leak around turbo: ching ching ching
smokes on start up only,poor sealing valve guides?: ching ching ching
no other repairs to vehicle

Is repair worth expense, i.e., what kind of additional mileage may I expect? Any thoughts appreciated.


PS: Are you suffering poor manual shifting? add Lucas to trans and it will disappear.

The MHG us ynneccesary for stock. The stock toyota HG will hold up to a lot of boost, for a long time. The important part is keeping the motor cool, not overheated, proper torque on the bolts, And good gas. A stock toyota headgasket and arp studs torques to 110 ft lbs will hold up to 350 rwhp, And maybe more. Detonation is what kills the headgasket. And yes, Once the repairs are done, You wont need any work for a long time. Itll be good for a while.
