I bought the Evo 9. It was a pump 100 lph (as it turned out after the purchase) replaced the walbro 250. The machine is certainly not as it should be riding evolution. But after replacing the pump, nothing has changed. So - the most interesting thing: boost leak (crimping) OK (tested more than once), timing belt OK (replaced just in case), spark plug new, new turbo - changed twice in the new! For the first time bought kunigava whole turbo, only the second time the cartridge. I have removed the cylinder head as soon as discovered that the pump is weak, the third cylinder piston broke off a piece of wall, but there were no injuries cylinder wall, so I replaced the piston and rings on all pistons and the other collected the car.
I took a friend with evo 8 MAF and BOV, nothing has changed. I examined the mechanism of mivec there too, all right, I changed the card mivec filling them with values ​​of 0 and 30, I applied power to the valve mivec reaction is - mivek works great.

What I mean, at the moment the car is no oil flow, compression 11 11 11 11 and the maximum load of 200 evoscan! And this despite the fact that the hose with the actuator removed The boost 14 psi max.

 

my log 1-2-3-4 and from 4

 

I also checked all the pipe and intercooler - all ok. AFR OK 14 idle, 12 - 11 redline. No catalitic konv. I drive without downpipe, no change.

 

What kind of boost control are you using?

You said you removed the wastegate hose and it still only boosts 14psi?

 

none


yes

 

PS. first stock turbo by use on evo 9 my frend, and boost to 1.4bar easy, but 2.1l on stock cranck and long rod.

 

solved! it easy, make external preload spring WG, and 316 load !!!!
