Acree's MAP 2.4L FP Black Build
Sorry for the delay. I've been in an Evo depression to say the least.
Headgasket blew for the second time about 4 weeks ago. It melted part of the head and scored the block. The engine is currently being pulled and fully disassembled at EvoD. The head is being rebuilt and the block is getting fully machined, decked, and reassembled with new bearings, etc. I am definitely fed up with doing the work myself.
They are adding a FPR since my Zeitronix was showing fuel pressure spikes up to 90 psi before the headgasket blew. I also picked up the English Racing custom 2.4L cams. A retune on 93 and E85 should net some really nice numbers. Needless to say, it's in KevinD's hands now.

The spike in the fuel pressure was due to me using the stock FPR with the buschur double pumper.

I use the stock FPR & Rail with the double pumper.. its fine. thats def not the issue, unless your FPR is rotted out inside?
-Acree
I use his double pumper though.. maybe he was showing the other one sucks vs his?
I ran up to 42psi with the stock rail & FPR just fine.. if there were fuel pressure spikes id see it in my AFR..
Here he said he was having spikes when the second pump kicks on.
While logging my FP, when the second pump comes on I was seeing 90 psi. It quickly dropped, but it was still there.
Then he told me to stay with the stock regulator.
I guess for right now, I'm sticking with the stock one.
Tscomp, it main not be showing in your AFR because it's not a constant pressure increase. It's a split second spike. But I can assure you, it's there.

Unfortunately, there will never be definite proof as to why I had so many issues. I have my suspicions, but there's nothing to be gained by posting them here.
I'm simply trying to get everything fixed and get back in the car. I've made 10 payments so far, and was only able to drive the evo during 1 of them. It's been down for the other 9.

I've had my car for almost 2 years, and have driven it about 1 month.
Just went through an entire build, and I'm right back to having problems.
hmmm..so hitting up to 90 psi under WOT is bad? what should it be around with a double pumper?
i run a blackops kit and it seems to hit a little under 90psi...thats not normal?

It's not just WOT, its ANYTIME the hobbs switch kicks in. And no, it's not necessarily a bad thing. Since it's an almost instantaneous pressure spike, I'm willing to bet that by the time the fuel rail sees it, the pressure is almost normalized.
Fluid pressure dissipates over distances in piping if the pressure isn't constant.

Some fidanza gears have the holes for DSM and EVO switched. Always make sure they are pointing at 12 o'clock when your timing is set for TDC on cylinder 1.
Acree you ever figure out what causing your head gasket issues?

Also I see in the picture on page 17 the the cam mark is 3.5 degrees to the right of center, isnt that advanced? I was under the impression that the mark should line up 3.5 degrees to the left of 0 on the 2.4's??
where is info to back this claim up? you're saying the EVO stamping on the cam gear is marking the wrong hole for EVO? thats the first ive heard that.. i have fidanza gears on my car. the dsm hole has no marking at all.. just the evo hole.
