Boost EVERYTHING! Challenge Priced New Turbochargers

In reply to hobiercr :

I don't believe so. What kind of RPMs will that engine turn, and what power are you shooting for?

In reply to Robbie :

Robbie, units for the small map are g/s. I generally just Google for the conversion, make sure to specify SCFM rather than just CFM. I originally thought the turbine outlet flange was proprietary, but now that I look more it looks an awful lot like the Subie one. . .

Update on Inventory: 

2 High-temp HP48s gone, both intended for Miata engines oddly enough. One of those johnnies left. List is as follows:

• 2 HP65 (larger size), upsized wastegate.
• 5 HP65, upsized turbine housing
• 2 used HP65, upsized turbine housing and wastegates. I'll sell at reduced cost, if no one wants them they go on my SN95.
• 1 HP55 (weird in between size, good for ~275hp)
• 7 HP48 (smaller size) 
• 1 High-Temp HP48

Ya'll must have lost your minds. Good luck.

Not sure exactly what that means, but I got my turbo today, the quality appears to be excellent and I went to the web site of the manufacturer, they produce turbos for many of the Chinese auto manufacturers. For my needs, this is a cheap solution to boost my project which is not a daily driver, but a fun toy. For a challenge car or similar project, these turbos would appear to be ideal.

Will these work for draw-through or what kind of seals are in them?

In reply to TheRX7Project :

My understanding is that they are not intended for draw-through use with liquid fuel: they were used in a draw-through setup on a natural-gas/liquid propane engine, but I can't recommend pulling gasoline through them.

Have you confirmed that the outlet flange is a suby one?

In reply to WonkoTheSane :

Outlet is unfortunately not the IHI VF series found on Subarus, it appears to be somewhat proprietary. However, all but the used turbos have a V-banded outlet flange that comes with them.

What are your thoughts on the HP55 on a modern 2.3L 4-cylinder, DOHC?

Whoops, missed that somehow.. thanks for pointing out the v band!  I'm running some numbers, but I think I'll be interested in that last high temp 48..

In reply to WonkoTheSane :

Well, I'm happy to give you and anyone else interested my number crunching spreadsheet to assist with that. 

Please do, as well as a number you're looking at for that turbo.. my user name @ gmail.com.

Thanks!

I posted this on my build page, but wanted to show it here as well. Happy with how this all fits and just need to clock the turbo outlet once it is in the chassis so I can see where it needs to point. I will brace the turbo with a bracket or brace to then engine block using the AC bracket locations as the ebay manifold won't last long with the turbo hanging down from it unbraced. I should have this back in my chassis next month and start on the rest of the setup if the weather gets more reasonable.

Engine's looking great! Can't wait to see the Spitfire all together running in reliable, un-British fashion!

Yes, with a Mazda engine, transmission, Subaru differential and Mazda wiring harness, this will definitely be more reliable (and leak less) oil than most Spitfires. With 4 times the horsepower it will also drive much differently but still  handle like a Spitfire. Thanks for contributing to the project!

Looks good, Dherr!

I snagged the 55 for the same engine, so I'm hoping to run it a bit more flow for occasional track work and around town fun.  We'll see how it goes :)

Glad a couple of these things are finding new homes. Wonko asked a great question about oil restriction:

These turbos have predrilled restrictors in the bearing housing. All they need is a -4AN feed line, and a -10AN return that is close to vertical with few bends. The less restriction they have on the return, the better they will perform.

That is good to know, I looked at my turbo and it appeared to have the restrictor in the housing so thanks for confirming as well as the sizes of the feed and return lines as I have both of these ready to go. Now I have to save up for my Megasquirt PNP

Elliot, I replied to your email a bit ago.

Thanks!

sek-see!

In reply to bluej :

Got it and replied.

Still got a number left, anyone? Is the price still too high for challenge use?

MAN! Would love for a twin snail, 4.8 LS Challenger, but I think they're too small (HP65) for the power level i'm looking for. According to my numbers, it'll choke a 2.4L  ( 1/2 an LS).  

In reply to 2GRX7 :

What kind of power are you shooting for? Another guy on the forum was shooting for around 600 with a set of these on a 4.8, and the numbers looked like it should support it.
