There's not much science to burping the system. Everyone seems to have a slightly different procedure.

Personally, I just give the upper hose a few good, solid squeezes while I'm filling the radiator, then cap the system and make sure the overflow tank is full up to the "full" line. Then drive the car for a while (enough to cycle the thermostat) and let 'er cool down. Repeat once or twice, and the system will pretty much purge itself, drawing coolant out of the overflow tank each time it cools down.


So, EMB & 310cc injectors, no AFPR, but a 3" DP and a serious FMIC. How much power / boost are we planning on, here? (and BTW, what are the specs on an SR20's turbo? I've never seen one.)

Power wise.. i'm not shooting for anything big anywhere from 200-250whp if possible. I just want something with some tq to get me through the twisties. IIRC my turbo is .80 A/R intake.. .64 A/R in the exhuast. Also known as T25g or .. GT2554R I believe.

your turbo is a good choice for those goals but your fueling setup is not, with 310cc injectors i wouldn't suggest more than 7-8 psi. btw your turbo isn't BB like a gt2554r

Right..it is a journal bearing.. but the specs line up with that. And regarding the fuel.. I just don't know about this fuel. Would a FPR + 190 LHP help?

yes an afpr so raise your fuel pressure should get you enough fuel. i came from a band-aided emb setup with an afpr and 305cc injectors to a mspnp and really crappy tune and picked up 50whp at the same boost.

Hey Pakman, are you using a restrictor on your oil feed line?

when you first fire it up have someone hold the compressor wheel still for about a minute...i forget why this is important but i assume it has to do with oil getting throught the cartridge and bearing before the wheel starts spinning, it wont hurt anything, just dont rev the motor, but you wouldnt do that anyways right? lol
