a big pump like that should either be feed from another primer pump or draw from a tank sump. Otherwise you risk chewing it up.

 

Why would it affect it? There should always be fuel primed in it even when the car is off

Amazing looks great! did you build the intake? looks like an EIP intake.

 

No I bought it from someone on here last fall. And Im not sure if its an acual EIP cannon but its an identical design as one.

I dont believe those have a built-in check valve. Which means it wont be primed and lead to dry-run upon startup. Not a good thing.

 

Its in the install instructions, maybe I am wrong but that looks to be an A1000.

Also to piggy back off of Ronnie, your turbo return line looks like its sitting flat and going straight forward to the timing cover. That also may cause issues leading to turbo failure.

Ya thats why I would put a fitting on the pan and since your there baffle it

Yeh np NikoFab, unforunatly i still havent gotten the car to run right. Ive been having some very weird issues with coolant and oil mixture. We have been chasing issues with the head gasket. Now after a month and a half later and 3 different head gaskets and intake gaskets i believe the problem lays in the water pump. My belief is that the area where the pump seals to the block through the timing cover is seeping coolant. Bit i will find out soon

Hes running a Twin Scroll or Divided setup. You dived and pair companion cylinders so you have no interference and optimize spool time. Ive seen 500-800 rpm faster response time on a twin scroll setup.

 

Some good info here

 

https://www.turbobyg...ength_manifolds

 

A design feature that can be common to both manifold types is a "DIVIDED MANIFOLD" , typically employed with " DIVIDED " or "twin-scroll" turbine housings. Divided exhaust manifolds can be incorporated into either a cast or welded tubular manifolds (see Figure 5. and Figure 6.).

The concept is to DIVIDE or separate the cylinders whose cycles interfere with one another to best utilize the engine's exhaust pulse energy.

For example, on a four-cylinder engine with firing order 1-3-4-2, cylinder #1 is ending its expansion stroke and opening its exhaust valve while cylinder #2 still has its exhaust valve open (cylinder #2 is in its overlap period). In an undivided exhaust manifold, this pressure pulse from cylinder #1's exhaust blowdown event is much more likely to contaminate cylinder #2 with high pressure exhaust gas. Not only does this hurt cylinder #2's ability to breathe properly, but this pulse energy would have been better utilized in the turbine.

The proper grouping for this engine is to keep complementary cylinders grouped together-- #1 and #4 are complementary; as are cylinders #2 and #3. Because of the better utilization of the exhaust pulse energy, the turbine's performance is improved and boost increases more quickly
