i dont think spot welding is necessary la. i am running 2jz in my 25years old nissan, no problems so far hehedoes silvia s15 can take the power of 2JZ under the engine bay !!! does any spot welding needed !!!!
dunno what speed cos havent really got around to installing the speed meter. engine 100% stock only. mated with 1jz manual gearbox. but even with stock engine, can make me smile already! 100% of the power can be transmitted on the road. dunno about blackie, got many many horses, sure even more happier hehehewahhhhhhh, tell me about 2JZ bro !!! how km/h u have run?? how many hp
its cheaper to transplant a 2jz inside a nissan, compared to rebuilding the nissan engine properly with correct oil pump n forged internals to overcome the oil pump problem. plus the torque of a jejet engine, no cow, no goat, nothing right n nothing wrong can beat that hehehe...transplanting a toyota engine into a nissan is like mating a cow with a goat
ITS JUST WRONG!
