Precision turbos have made quite a name for themselves for some years now, and in recent times they've really cranked up the development on turbos in the power ranges that Ecotec runs with.  Hahn RaceCraft goes way back with Precision, as the owners of both companies (Bill and Harry) used to work with one another in each other's garages, way back in the 1980's as each was starting their respective businesses.  They've both come a long way, and this combination of their talents is a proven winner.


With Precision's recent emphasis on this power segment, it was a natural for us to replace our aging Mitsubishi turbo line with these ultramodern Precision units.  So we stepped up...big time!  The concept here is already proven, as we've used this LNF mounting housing approach for years with the Mitsubishi S20G.  Now it's just chock full of awesome, for not only have we added a sweet Precision external wastegate...we now offer the entire spectrum of Precision turbos in this system!

We retain the stock turbo manifold, for it's well-designed and proven to support higher power, both in terms of flow as well as in durability.  We provide all the parts to mount the Precision turbo of your choice, making the entire installation a one-stop affair.  From our innovative mounting housings, to every single bit of plumbing and hardware, you can have a Precision turbo and external wastegate mounted in an afternoon. You don't even have to remove your stock turbo manifold from the engine to install the Hahn solution.



The system also includes its own 3" 304 stainless steel downpipe.  Starting with a super-strong thickwall elbow at the turbo outlet, the pipe transitions into mandrel-bent tube.  The downpipe can be had one of two ways: either with the standard 4-bolt flange attaching it to the turbo, or with a trick-looking and easy to install 3" V-band connection to the turbo.  You can also have us add a metal-hydride high-flow catalytic converter, as shown in the last photo above.  Expertly crafted, with the best welds you'll see anywhere. If you'd like to add a second O2 sensor bung, click here.

You'll control your new Precision 39MM wastegate much like you do the stock turbo's internal wastegate actuator, using the PCM-directed solenoid.  But you'll have nearly endless boost tuning options now, as we send along a box of different wastegate springs so that you can nail it, the way YOU want it to work.  A dump pipe for the wastegate is also included.

Hahn RaceCraft's proven LNF turbo concept, now better than ever with Precision Turbos!  Please let us know if you have a Precision turbo desire that is not reflected in our offerings here.


FAQ:
Q: I am looking for a turbo to be spooled by 3000-3500 rpm and around 400whp. I'm not expecting to bolt on a turbo and get those exact results. It would be fully bolted, Meth injection and tuned aggressively by the end of it. 

​A: If you plan to stay with the stock engine, the 5531 and 5831 are great choices.  If you intend to build the engine now or later, a 5558 or 5858 is worth considering.  High-achieving builds of 600+ WHP are 6262 territory.  

Also keep in 
mind, no matter which turbo option you choose now, swapping in the Precision turbo of your choice in the future will be very straightforward.  The Hahn RaceCraft conversion will already be in place, so all you'd have to do is swap the turbo itself...and we'll get you a great price on the right unit when the time comes to bring more game.  Simple and affordable when it's time to step up!

Q: What else do I need to install the Hahn/Precision Turbo Upgrade?

A: An external BOV system and a new tune, both of which we can also provide.  We would assume the machine already has full bolt-ons.

Q: Is it necessary to relocate my MAF to the lower charge pipe?

A: No.  Even with an open (atmospheric) BOV, competent tuning can accommodate the MAF in the stock position in the air intake.  We also offer recirculating BOV's for those who'd like the most OEM-style result.
