Recommended Posts

  • Moderators
so how long does it take to get a BNR turbo? I tried to get in contact with them 2 days ago haven't heard back

 

Just call the number on the website--Bryan will more than likely pick up the phone during business hours.

"Bullet-proof" your OEM TMIC! <<Buy your kit here>>

 

Not currently in stock :(

^how much did that run you? What hp are you making with it?

 

It was around 950 I believe with shipping. Not sure about HP it hasn't been on a dyno still being E-tuned. I'm running it on stock fueling for now hitting 15 psi(should be about 17 psi when the tune is done)

17psi sounds low for an 18g??? I'm hitting 20-21psi on my BNR16g, running 650's

 

Maybe comparing apples to oranges here, though.

All I need now is a hill holder and a center passing light...

Same here.. 20-21, bnr16g, 650s

I am hitting about 18 psi now that the tune is almost complete. I am using a process west clone top mount and 93 octane fuel. The limiting factor is my stock injectors.

 

Did you upgrade the fuel pump? just curious.

Well... the pull does not start until almost 4000rpm, the IDC is over 95% and there is almost no timing. That log tells us very little other than someone was really trying to stop a knock event (and it still happened at the end). I would love to see a log from 2000rpm-redline at WOT.

I don't see any knock in my logs. I would never go WOT at 2000rpm that just seems like a bad idea. Do you have a problem tuning people to 95% IDC? It never actually reaches 100 no matter what. Anyway, I had a stage 2 WRX that ran near 100% IDC for 2 years with no issue.

It's not a bad idea. It's often necessary for tuning.

 

I see. Everytime my car has been tuned they usually logged idle, part throttle cruising and then like 3000rpm-redline. I guess i'm thinking of mashing on the gas while at low rpm in a higher gear

hey all new member with a fresh blown turbo (second one on the car) after looking as much as my eyeballs can take in, im in need of some pointers (not new to cars or Subarus, but this IS my first turbo car that i have owned my self, and after a week of VERY bad luck (unrelated to the car) i pick up my new car (05 LGT) and the turbo blew on the very first drive i took it on.. vehicle history has this being its second turbo, and less than 9 months old 8k miles on it (a cheap factory reman grrr)

 

all other issues aside (will be doing a full top to bottom cleaning and inspection as well and addressing what i think is the cause, and not just band-aid it by just replacing the problem) i have been looking for a turbo replacment that will fit my criteria.. that being

 

1) stronger/better quality than the OEM VF40...

2) Direct drop in bolt up OEM like replacment and fitment

3) NO tuning REQUIRED when running just off the spring... safe/OK to run while staying off boost as much as posible untill i can get the tune done.. no need for imedieate supporting fuel delivery mods...

4) If im going to do this im going to do this right and give my self a bit of wiggle room.. from what i seen of this turbo it seems to fall flat on its face up top.. so looking for a turbo that will retain stock or better spool charictoristics, but breath a bit more up top.

 

after all of the poking around it looks like the BNR VF40 EVO 16G is the right turbo for me... but im a bit fuzzy on some of the details... will this turbo in fact meet my criteria?

 

i will be supporting it with the required filtered oil feed line supplement, and OCV replacments... also due to the fact that i will be doing a tear down of the complete intake track (up to the heads) to clean out as much of the small debris as posible, im thinking now would be a good time to get some TGV deletes and the Racer X FMIC, perrin inlet tube, and a silicone (firm) line for the PCV return hose...

 

not only because of the turbo blowing up, but mainly because this a new car to me. i will be doing full maintanence on it as well/// plugs, full flush, full fluids... just putting that out there...

 

one last thing i was not able to see an order page on the BNR site.. am i missing something? and does anyone know what the rate for the returned core?

 

thank you all in advance

 

:)

 

almost forgot: 05 LGT 5EAT just under 130k lots of the big item maintanence was done before i got the car... only mod on the car is and Invidia catless DP <(edit for this info)

if you're going to run the 16G, install a boost gauge and stay out of boost. Also, whatever you do, you should worry more about debris in the oil than debris in the intake. Replace the oil cooler, and drop the oil pan to check for and clean out debris. Finally, remove or replace the banjo bolt filters.

+100000...

 

And as much as you may want to avoid modifying the fuel system, a DW65c pump is an easy install and could potentially save your motor... provided you haven't circulated the turbo mess through the oil in the block.

 

It's highly likely the second turbo blew because whomever did the first swap did not get the contaminated oil resolved.

First and foremost, its a 5EAT. Dont install a larger turbo without addressing the weakness of the transmission first. Valve body upgrade and a oil cooler at a minimum.

 

Second, a 16g on stock fuel is a stage 1 tune. Waste of money. Buy a VF-40 CHRA ($350) and rebuild yourself if that is the case.

 

Pass on the TGV deletes and the RacerX FMIC. TGV deletes are major overkill for a 16g. Will delay boost slightly and gain maybe 1-2whp at the top. RacerX FMIC, nuff said.

 

Perrin inlet tube is not required and will require re-routing and plumbing of all vacuum lines that return to the inlet tube. It is not specific to your car.

 

Silicone PVC return hose is your call. Not necessary, but your call.

 

DW65c will not "save" your motor. It will decrease IDC by 1-2%. Thats it. If it aint broke...

 

But, you do have the probable contamination in the block and oil cooler to deal with as well as some other possible gremlins. If its the second turbo in 8k miles, I would be prepared to pay handsomely to get it all straightened out now.

 

Sorry to hear about your "new owner" troubles. Not how we want to get things "rolling" with a new Subie owner.
