icapture Posted May 10, 2009 Share Posted May 10, 2009 About to fire up my SR20DET once my last silicone intercooler connector gets here. And i was wondering, do you guys think the fuel pump on the 280z is enough to fun a SR20det at stock boost? I mean, the motor is quite a bit smaller than the stock L28 that came in this thing - so it should be fine right? Just as long as it turns on - haha.

280zjoel Posted May 10, 2009 Share Posted May 10, 2009 I do not think the stock one will cut it, I could be wrong though. When i did my swap i had to upgrade the pump. Quote Link to comment Share on other sites More sharing options...

When i did my swap i had to upgrade the pump. did you have to replace it before you drove it? or did you drive it for a while then replace it? I am dying to get this thing out of the garage on its own power! if only for 5 min. but i dont want to do damage, so if i HAVE to wait - I will.

theghosttanker Posted May 10, 2009 Share Posted May 10, 2009 It's not the displacement of the motor that is important, it's the horsepower you expect to make with it. If you expect a big jump in horsepower with your swap, then you need to use a bigger pump and maybe even larger fuel lines. And yes, you can indeed do damage, if you run a turbo motor lean even briefly it can detonate. Quote Link to comment Share on other sites More sharing options...
