Question MR2 Question..

i definately got the MR2 to run lastnight. 92, 5sfTe. it runs fine other than the misfire due to the old plug wires. i'm not producing any boost tho, can anyone explain why!? a friend tells me that i wont be boosting until i'm under a load. but i'm not sure. any help would be great.

ok everything is definately tight and sealed. it's runnin reaaaally friggin rich that i'm shootin flames out of the cat. now, could the reason that i'm not boosting be that iiii don't have check valves? because thats the only other thing that comes to my head.

do you have a boost guage? I'm guessing your actually driving the car to see if your getting boost because my car gets about 20psi of vacumm at idle and doesn't start to boost till 2600 rpm's or so. if you do not have spark, the car will also have no balls. go ahead and replace the wires and plugs if not already done.

Mike, i'm using stock injectors and i have an FMU. i've read that the stock injectors will be fine with my setup. and although the car is still on stands we were still pushing it under a load. i'm waiting on a new slave cylindar, however. mine was bad, it would be in first, clutch all the way in and the axle's would still be turning. yes i have a boost guage and mine too gets close to 20 psi of vaccum at idle. now i dont understand why it's not boosting. which brought me to the check valve's..

being on jack stands does NOT place a load on the engine.
