Turbo selection for 200+ HP 1.5L IDI

I need to make more power from my 1.5L "Franken" engine. Currently making 167 HP at the wheels, using a Dieselmeken pump rated at 90cc's and 6,000 rpm. Using a Garrett GT2056 turbo and air/water intercooler.
I'm looking to make more power for next season - shooting for the high side of 200HP. Driveability is not a concern, as this engine will only be used for land speed racing attempts.
So, anyway - with an even higher output injection pump (let's say 125 cc's), what turbo would be a good match to allow 200+HP at 5,000 rpm or above?
I have had one recommendation to use a GT2863R turbo. I'm no expert on reading turbo maps and making turbo selections - I'd be happy to hear some more recommendations, keeping in mind this is a racing-only application.

I would go with the Hx30 or hx35 off of a dodge. I wouldn't use garret anything. Garret makes the most turbos which is great for oem, but Mitsubishi and Holset make turbos well. They come stock with the 360 main bearing which helps it live and spool. I cannot find the squirrel turbo calc site to put in the numbers to a map. Alcaid will have to chime in if he has a map calculator. He may give a different possibility as well. I know I have the He 221w and it is a "big" turbo, but it is very streetable. Something bigger may not be streetable but will give you the most air for your fuel.
Here is some maps I found for the holset turbos

Alcaid said someting about using 3 turbos in compound he could get 9bar on a 1.6TD... i bet you'd need more intercooling then...

your current turbo should be able to do that, you may just need a larger exhaust housing, and perhaps more fuel.

I have entered into a conversation with Alcaid on the topic - investigating Holset options.
RJ - I'm no turbo expert, so thanks for weighing in. I wasn't aware that there were larger exhaust housings available for the GT2056. If there are, I'd appreciate any knowledge you might be able to share.

it's something you'd probably be better off talking to alcaid about as i don't really understand sizing the of the turbine housing, and he does fluently. perhaps calling garrett/honeywell will be helpful, especially since you're setting records, and breaking them by 35mph haha. and also setting the record for a 1.5 higher than the record for a 1.9

...and the 3 Liter record.
I'm planning to work my way up in displacement.

The GTX2863R you have been suggested is NOT a good candidate, compressor is not set up for high boost numbers at all.
Anything from Garrett close to having a compressor map that would be suitable for the swallowing curves of your 1.5 is the GTX2863R (Rally), rally version has a lower trim comp wheel that is very promising but even the smallest housing has a turbine choke flow that is somewhat too high.
You really must set yourself an exact target, you are very close to needing compound to be able to get the boost needed at a decent compressor efficiency. Turbo sizing will then be different, but not impossible. Biggest mistake everyone makes is not taking into consideration that also EMP of both stages are compounded.
For 125cc, the HE200WG-5cm is enough turbo, 200whp, but there are other candidates if stretching it further

HX30W Super and your 1.5 should be capable of 240-245whp with a 150cc+ pump
65/52mm turbine wheel, 6cm turbine housing, T3 flange, fits your manifold with no adapter needed
Comp wheel is 78/46mm 7+7 blade
It will be laggy but will work on the salt
Should be upgraded with a custom billet comp wheel with 11+0 blades and extended tips for better durability, more boost at the same RPM, better compressor efficiency at high PR. I can get it developed for this project
Should get you to 250+whp

Hey, I was just browsing and this 200 hp 1.5 liter DIESEL caught my attention. How do you keep engine in one piece and not flying everywhere at 6000 rpm? I think most 1.6's max out at 4250???

The devil is in the details.
Dieselmeken (Goran Lindgren) did the injection pump. It has no problem spinning to 6,000 rpms and a little more.
Here's a video of it running at Bonneville. It might be a little tough to see the tach, but the 1-2 shift should be right at 6,000, as are the 2-3 and 3-4 shifts. On this run, we hit just a bit over 135 mph in 4th gear, turning about 5,100 - 5,200 rpm.

It's probably easier to see the tach in this video. This was taken on the "backup" run for the record.
The sun was in front of me for this run instead of behind - less glare on the gauges.

Thanks. I'm looking to build a stronger engine during the "off season", with the intent of testing at Ohio in 2015, and returning to Bonneville in 2016.
There are at least 3 other guys chasing these records. I want to be able to defend them if necessary.
