Well I am looking over my options for a motor I want to buy for my 1992 Nissan Sentra SE-R. I narrowed it down to 2 options, and was wondering what the people on this forum would choose. The first option is a SR20DET motor is from a car called a Bluebird, and the Second SR20DET is from a Pulsar GTi-R. My plans are to just get the motor tuned and run higher boost, no cams, and no turbo upgrade. Here are the stats on the motors... The Bluebird motor has a T25 turbo, and 370cc injectors, with an 8.5:1 compression. I have seen this motor produce 264whp, and thats about all you can squeeze out of the stock motor, with higher boost. Parts for this motor are available in the USA, the parts are identical to the parts that go on the US SR20DE which SE-R's come with. The Pulsar GTi-R motor has a T28 turbo, 444cc injectors, quad throttle-bodies from the factory, an 8.3:1 compression, individual oil squirters for the underside of the piston(bluebird does not have this) and a much stronger head and block. The bad news is the important parts that could break are not available in the USA, I would have to find a way to get them from the UK or Japan if a water pump, oil pump, powersteering pump and a few other things decided to go bad. I watched a SE-R with this motor Dyno at 294whp, and was still running a little rich, so could easily go over 300whp with just raising the boost. I am really thinking about getting a Pulsar GTi-R Motor, but I am not wanting to walk into a mess with not being able to get parts for it. What would you all choose, a Bluebird SR20DET or a GTi-R SR20DET?
