Default What else...

What else can I do to make more power???

Right now running an M4 fuel pin, HE351VGT turbo which will be tuned in shortly, valve springs, low pressure piston lift pump, 3800 rpm spring, 4" exhaust, intercooler, BHAF. I don't know where else to go from here, besides maybe twins. I was thinking about a tubular exhaust manifold, which I will build when I get bored, but are there any other things I could try before that (twins or exhaust manifold).

Really looking to stay with the VE pump, I know the P pump would be where it's at, but I also have $28k of tuition to pay this semester, so that's not gonna happen.

Guess I am looking at the M&H dynamic timing spacer and smoke control device. We'll see how those work before doing anything else major.

P-pump is unfortunately not in the budget right now. If i were to go P-pump, I would go twins as well, though.

you could probably get some 5x.012 injectors or maybe some 5x.014's but those may get egts too hot since those he351's have tiny housings.

This is the VGT version, so I could get more injector in without the EGT's going sky high. It opens up to a 25mm housing, IIRC.

Got any links to the timing adjustment? Would this take the place of the M&H timing spacer?

Also, any more info on the pump and how it works being a DD?

I have the exhaust and fuel pin already, as well as the 3,800 spring, valve springs, studs and o-rings. So I am pretty well on my way.
