Okay ijust bought a 91 nissan sentra se-r. They swapped out the engine for a jdm sr20de. I dont know sqaut about sr20's in a se-r so any help or links would be great. The seller said that the jdm swap gave 10hp any more extra bonuses? Also the car shakes alot, whats with that? And the clutch seems like it could be replaced ofcourse this is my first manual car so it will probably need to be replaced by the end of the summer anyways. He also said the car could only have 89 octane gas and the rev limit was 7500 rpm true or false? Im 17 and this is a car i think i could only dream of having so any help at all would be great. Thanks.
