EVO II slow

[Liberoz]

one tooth out on the cam gears ! I'd be checking that

 

[Hypo]

How does one check that?

 

[rob323]

Pull the top timing belt cover off, remove the spark plugs, rotate the crank til the timing marks align and No.1 cylinder is at the top of it's stroke and then read VFAQ. The marks on the cam gears should line with the top of the head.

i thought that you should be able too run a ruler or straight edge through the cam gear timing marks or they should run with the top of the head

Woops , you are correct, I have amended my post.

Someone said that it could be the fuel pump. Doesn't the fuel pump just pump the same amount of fuel at all times and the injector useage and return line resolves the excess?

 

[rob323]

If the car is alright when up high in the rev range, then I wouldn't suspect the fuel pump. It is normally at the top end of the rev range that a fuel pump will not keep up with the required demand.

But, its an easy check to hook a remote fpr gauge up and go for a drive and make certain it is not the problem.

Are you coming on the cruise on Saturday? If so, then there will be a heap of us there that can pretend to know everything and point you in the wrong direction .

 

[Hypo]

Won't be able to make the cruise.

I have a Walbro fuel pump at home so I might chuck that in and see what happens and if it resolves the issue.

What is the symptoms of a split intercooler pipe?

Should it get worse the higher up the boost range I go?

 

[CLuTZ]

Have you still not fixed your car yet!?

What things have you checked?

Yes.


Depending on what side the pipe is on

Between turbo and throttle body=Loss of power an usually a high pitch noise

Between AFM and turbo= usually a similar noise but the car will happily go hard, and at the same time will be running lean.

What things have you checked?

Still have to do compression and timing.

Changed

Not changed

do a comp test-its free/very cheap

 

[robevo]

I would do a comp test just to be sure mate, Does it have a cat as it could be blocked, also check the end tanks of your intercooler, they could be blocked too.

What is the compression meant to be on a EVO II?

 

[Dean]

180 across all 4

 

[Hypo]

180 across all 4

So what is it meant to be on a EVO III?

I thought EVO III was 180 and a EVO II was lower?

 

[DOUGMO]

thats the compression ratio

compression ratio and cylinder pressure are different things

Hmm all good then.

Only got between 135-140 on each cylinder.

What issues would this cause?

slowly dying but not dead
