900-1200WHP Boost help, 333CID Gathering parts not for my boost build.
5.4 Iron LSX (LQ4 block, 4.8 Crank). Current in the collection are LS3 heads, TSP rockers, block, Lunati 6.300 rods, arp main kit, custom turbo cam, LSA oil pump, timing set and 1/2 head studs.
Blocks being machined now and we will place the order for the pistons based on the specs of the block (naturally). Pistons will be RaceTech and then coated by swain tech. Target compression with my heads will be 9.1.
I dont live in corn country so I cant e85
so 93 octane with boostane it is.
The question:
What are the 1000WHP gas guys running for turbos. I am thinking something similar to a pair of 6468's T4's 1.10ar or similar. Perhaps some of the smaller BWS300 line to keep that cost down, The plan is a China special pair of ebay turbo manifold, but jet hotted. Or should I just single it and be done. Would like to be hard into boostunder 4Krpm

I'd give lil john or jose at forced inductions for a recommendation on a setup like that. Being that it is a little different than your run of the mill ls stuff, very short stroke, big bore, long rod deal. Cam selection will be important as will the tune up with the increased dwell time at BDC and TDC.

I actually think I'm going to lower my power goal for a maximum 1100 but normal boo setting in the 800s. I'm going to be running it on aem infinity. For twins I like something in the area of 6264 or 6468 but Borg Warner does have a 6368 on the inexpensive side. However I'm uncertain on single turbo set up I like the idea of the simplicity and the cost savings but I'm very unsure of when it comes to usable used boost. Lag monster is not what i want.

Asking for 1200hp potential on a smaller motor and hard boost under 4k is asking a lot from cheap turbos.
A pair of BW SXE362's might be close, or if the lower rpm really is more important, a pair of the SXE257's might be better with perhaps a little less top end ability

2500 for turbo or turbos would be nice a pair of 360 jb s363 t4 or a single 88-95mm unit. Hard boost at 4k is target. Currently making 600whp on a 2.5 liter with a 5858 at 21psi

The high compression version was the 2nd phase of the build. He did a low compression smaller cam version too.
His build gives you a great idea of what works, and answers your turbo sizing questions.

If it were me Id stick with the stock stroke and run a pair of basic S366's or 64's or a billet 76. The short stroke deals are cool and rev high and will make a good pk number but you will make more power on the lower octane with the longer stroke. It will spool better, make better use out of the sq heads, and have a lot better power under the curve.

Have you considered the use of meth injection in place of the octane booster? With the help of an intercooler, similar results of E85 can be found simply by using meth injection (and its a LOT cheaper).
Sounds like you are trying to save $. You likely would have less into a large good quality BW like an S400 rather than going with a set of China ebay twins I would think.

Cheap turbos are bw to me, the S363s would be the cheapest I would go, but I have been talking to my tuner who is trying to talk me into a procharger F1-x. Going to be using a valve spring with a 175 seat pressure and .685 lift, rockers will be connecting by hydros, looking at options now.
Unlike the 240 there is room under stock hoods for more activites. about 6 inches of forward space.
As for the stroke I'm gonna run the short, cost more year, but it will be fun in the revs
