I guess someone should ask when or if they will have one for the ltg platform. https://zzperformance.com/ecotec/fue...l-pump-upgrade

Save your money and go OEM for a HPFP.

Interesting... I'm hoping to have one done within the next month or two. It's already about 50% done. I guess the LT1/4 modication thing to is no big secret lol

Awesome! This will be huge for this community!! As the factory pumps are worse than the lnf ones on the cobalts and saturn sky etc.

This is good news! At least we will have something happening for this platform by then! I think these motors can make good power, but are limited by so many things.

Agreed!
With an upgraded HPFP running E98, with Jason's bypass valve on the stock turbo, I bet I would be approaching forged internal needs, even bone stock, as far as power#'s go.

Hoping the weak link is head bolt stretch by the time I'm done with forged bottom end, upgraged HPFP, and EFR7163

I hear the head will lift at around 425? I'll be looking into some sort of ARP stud kit if possible.

Its fun watching the LTG landscape change over time and mature like similar platforms have in the past. It reminds me of the Mits 4G63 2L turbo way back in the Eclipse and Plymouth Laser days. It started out stock at 195HP but within about 6 years the aftermarket had the thing making 500WHP+. Also like the EJ20 and to a lesser degree the EcoBoost Fords.

Its more complex and probably more costly than the 1990s, but the progress is marching fast!

Allen's Camaro that went in the 10s made 430+ a few weeks ago, as far as I'm aware no indication of the head lifting, or even worries.

I figured it will be past 500HP crank before stretch... 430+ at the wheels proves that theory

What all is done to the 430+ car so I can start putting together the list!

All of our bolt-ons, forged internals, slicks & skinnies, and a Z54 turbo. Nothing crazy honestly. I added up all the parts last week and it's just under $6k for the full build.

Stock cam or ZZP cams (as advertised) or custom grind?

And yes I am right at $8000 for a full build paying someone to help do the work for me... that include $1500 for the junkyard pull out.

Zzsteve · 08-16-2018, 04:53 PM

It has our cams/springs in it.

***I have custom head studs in production. there were supposed to be here already, so they are coming REALLY soon
