Mack Posted April 11, 2007 Share Posted April 11, 2007 I swear, it looked smaller in the Ebay ad. Its a VNT turbo off of a GM duramax deisel. I figured since everyone is running Holsets, why not give this a shot with megasquirt as the boost controller. the vanes are controlled with a PWM solenoid.

proxlamus© Posted April 11, 2007 Share Posted April 11, 2007 omg that a HX55? Quote Link to comment Share on other sites More sharing options...
Mack Posted April 11, 2007 Author Share Posted April 11, 2007 NO! its a garrett! frame is supposedly a T58-ish? but with the VNT or its also called an EVRT turbo, spool up isnt so bad. this is going on my 3.1L frankenstein headed beast. there was a guy running one on a 2.3T SVO stang and he was getting like 20lbs at 3k rpms.

slownrusty Posted April 12, 2007 Share Posted April 12, 2007 This is an actual T58...it was so big it did not fit inside my 280ZX engine compartment... Yasin Quote Link to comment Share on other sites More sharing options...
(goldfish) Posted April 12, 2007 Share Posted April 12, 2007 I think I need to check out your build for motivation, mack. Quote Link to comment Share on other sites More sharing options...

Mack Posted April 12, 2007 Author Share Posted April 12, 2007 I was kind of concerned about the fit, but I figure with my Frankenstein head, I wont have to worry about the intake getting in the way. I have that side JUST for the turbo and manifold. tends to free up a lot of room. from the dyno charts Ive seen,. the Ford PSD 6.0 and chevy 6.6L deisel engines equipped with this turbo are making well over 300lbs/ft at only 1500rpm. so, that means that they are making boost pretty low so, take my 3.1L gas engine with 4 valves/cylinder and I should have NO problems spooling by 3k rpm, even with a .90 exhaust A/R! is my logic flawed?

steveosupremeo Posted April 22, 2007 Share Posted April 22, 2007 timz, is that a custom exhaust manifold or what, it looks like the euro manifold welded together without the bellows? just curious. Quote Link to comment Share on other sites More sharing options...

240hoke Posted April 22, 2007 Share Posted April 22, 2007 In regards to the Varible vane turbo.... has anybody had any problems with vane failure due to EGT's?? It was my understanding that the reason they have not had variable vane technology until recently (this year I believe) was due to the higher gasoline exhaust temperatures...which were were too much for the materials used on diesel unit.

Mack Posted April 22, 2007 Author Share Posted April 22, 2007 I emailed a guy about a few monts ago regarding a turbo set-up I saw on a forum. He had an SVO mustang and claimed 20psi by 3000rpm. this was his original post............ Well, someone had to do it. So I (we) did it. Many thanks to Mike Krader for many hours and machine work. Here's the details: It's a GT3782VA, which is a GT37 turbo with variable geometry and an 82mm turbine. This is commonly known as an EVRT turbo used on the 2003+ Ford 6.0L Powerstroke diesel. How does it work? Well, good and bad. For a T58 frame size turbo, it spools fairly quickly. I can control it to almost choke off the exhaust to get it initially spun up, and see 20 psi boost at 3000rpm. Then I back off the vanes to where it needs to be. It is a bit slow in transient response for the street, but may be ideal for a drag race (especially an automatic) situation. Control is via a +12v PWM signal. Many commercial boost controllers could probably run it with a small circuit added to handle the 3.5A of current the VNTCV (VNT Control Valve) solenoid requires. I now have about 1000 miles on the setup. It works well, and has had no reliability problems, even with EGT's exceeding 1700°F. Yes, I know it's high, but 16psi at 7500rpm is so much fun;) So, I know, you want to try this, how do you get hooked up? Well, first be aware that this is not for the faint of heart, and certainly not for those of you who want a packaged bolt on with no frills. For the required adaptors, Mike is the man, and I can put you in touch with him. For the turbos themselves, I might be able to help you, as I seem to have a few. This turbo is not ideally suited for such a small engine as the 2300 on the street, but a 4.6/5.0 might do very well, or an all out drag racer will certainly appreciate the airflow this thing is capable of. Pics: GT3782VA on my SVO (http://www.ndperformance.com/projects/evrt/) I am going back to a conventional turbo, but then, that will be on the new 16v engine (wink, wink, nudge, nudge). My car sees 100 street miles per day. It's not a drag racer. But to those with the means and the patience, the potential of this turbo is there. Let me know what you think. Thanks! I emailed him asking a few questions hello, i saw tht you have done some work on VNT turbosin the past, I hope this email still works! I am contemplating installing one of these on a specail 3.1L DOHC nissan I6 engine and I am going to be running MegaSquirt EFI with ignition and boost control as well. I am wondering how many miles you put on your ford 2.3L and also how much HP this turbo is capable of supporting. any info you can provide me with would be GREAT! Do you still have some of thses for sale, by chance? and this is the response I got... this was before I bought my turbo off of Ebay for $125 shipped to my door, lol I put about 17k miles between the two different types of turbos (smalland large turbine). They are capable of at least 550hp. EGT's were in the 1500-1700° range, and no problems. I have three turbos left. Two small, and one large turbine. The large and one small have a threaded insert (1/2" NPT, IIRC) in the oil drains of the housing, to make plumbing it easier. Both were on my SVO, with more miles on the small turbine than the large. The other small is brand new, never run. If you'll buy all that I have left together, I'll sell all three for $1000 + shipping (a steal). They weigh 42# each. hope that helps a bit, but probably not, lol Quote Link to comment Share on other sites More sharing options...
stony Posted April 24, 2007 Share Posted April 24, 2007 Since we are all talking about big turbos!!!!!! let me wipe mine out :> Quote Link to comment Share on other sites More sharing options...
Ledphoot Posted April 24, 2007 Share Posted April 24, 2007 I really need to get into the 21st century.. Fuel inj and turbos just freak me out. I like carbs...but man that looks powerful! Quote Link to comment Share on other sites More sharing options...

The thing about diesel engines, is they don't rev very high in the first place, and at 2-3000RPM's they are spewing more exhaust through the turbo than your 3.1 at 5-6000RPM's.
