Borg Warner EFR Series Turbo's V 2.0

 

Link to the first attempt. A wealth of knowledge in it. 

annnnd go!

[Mick_o]

So how about those EFR'S huh? 

Pretty cool turbos!  ?

[Piggaz]

Usmair, have you driven your car yet?

[33GTRV]

Page one bananas! 

 

Wait. Not a wasteland thread? 

Well umm. Yeah. Efr seems to be the goods. Convinced a mate with an emo 10 to buy one. Will see how it drives in a few weeks. 

[sneakey pete]

What size did he get?

[usmair]

here you go guys. 

BW 8374 1,04

Built head with studs, gasket, springs blah blah

Stock bottom end

HKS 256 drop in cams

CRG split pulse manifold

e85 

504kw at 30psi. I told tuner to cap it at 30psi due to stock bottom end. Should see another 30-50kw with 4-5 more psi.

30psi around 4600rpm.

Its a little laggier than my mechanics (he gets 33psi by around 4400rpm), which I think could be due to having a massive 60mm old tech gate or perhaps due to it not being a built motor.

Still a bucket load off fun. Starts to wind up around 3k and really picks up boost 4k

Dyno run below and dyno sheet attached.

I put a thread up asking the Mods to open up the EFR thread again......they just deleted my post.

Seen it. Half the reason why I made this.

[Nismo 3.2ish]

Someone had to start it again, lets hope it does not get bogged down with BS ?

But it is hard to find info on the EFRs ?

I think because there are so many build types for Skylines now ranging from stock  to over 3.2Lt , it is also hard to have back to back comparisons.

But from what I can find out,  the EFR8374 will get me going quicker, with a much better transient response and roughly to the same top HP as my PT6266 Gen 2 ?

Hopefully some back to back comparisons

[admS15]

Want to see comparison with -5's. LOL, only joking.

It would be good this time if the bullshit comments are kept to a minimum and maybe another thread started for bw only dyno results. Just so there's a place for chit chat and one for results. The old thread did lack results. Just a suggestion. Carry on[emoji106]

Do you have the speed sensor installed on your car Usmair?

Be interesting to see where you are at on the compressor map ?

everyone chip in for it and i will haha

its staying put as it is... until something eventually blows

[Piggaz]

It's like $200. Don't be a tight ass. Wire it back to the ECU. Better than blowing a turbo!

Are you running E85?

Good to see this thread back in action!

yes

[NISR32.5]

500kw is up there. I'm itching to get mine sorted now

[s2d4]

Hopefully people will start posting turbo speed, since it's absolutely crucial for these EFR's

[Dose Pipe Sutututu]

@usmair solid result bro, should tell Adam to strap that car down properly.. she's a little bouncy lol
