its a ct26
best supra motor is the 2JZ-GTE was factory in 1993-1998 Toyota supra twin turbo, was also the fastest and lighter than its predecessors...
Taking into consideration this is stock vs. stock, and we're comparing a Toyota Supra Mark IV (either normally-aspirated or twin turbo) to a Acura RSX Type S, then either iteration of the Supra is faster.
what year is your your car and what type of car ie..supra, soarer etc...
The cars that have a 7MGTE engine are a 1986.5-1992 Toyota Supra MKlll. This car came out in Japan between 1987-1993. The Toyota Cressida Mark ll, the Toyota Chaser and the Toyota Crown also have this engine type.
Full synthetic SAE 10w30.
10w-30
Low revs between the range of 2500 to 3500rpm cause the lag you notice before the turbo has kicked in because you need around 3500+ rpm for enough air to be dispelled by the exhaust in order for the turbo to operate optimally. it is more noticeable on older cars due to the inefficiency of carburretters and older type fuel injectors thus compunding the effect of a turbo, who'se job it is to force air into the very same (inefficient) carb that is slowing it down in the first place..
I usually use 5w-30 in mine and put some oil additive so it can run smoother
Was built for R12, can be converted to R134a.
An example of a Toyota commercial vehicle can be anything from an Avanza 1.3 S to an SLWB Coaster Turbo. It all depends on the type of vehicle you are looking for.
