All we can say is wow! hands down best drift turbo on the market...
bare with us, we are almost done with a really in depth write up on this turbo and combination.

in a nutshell, the turbo has plenty of power and hits boost at 2000rpm, no clutch popping. just throttling of the gas breaks the tires loose.

Dyno is sceduled for next wed guys.

we have a short video...enjoy

YouTube - EFR Kit.avi

had emailed you...should've figured you were on here too lol...anyway I asked you a few questions about the performance, etc as my powerlab t4 ts manifold that I've been waiting on for a month...should be here tomorrow and the 7670 isn't far behind to go on a sr20vet build I've put together. A few intro pics of the build are on this forum. I had heard that alot of people were waiting on these but apparently treadstone is selling them on ebay in stock...so I've got the ls7 option too or grab an efr and see what my setup will do.

manifold came today

Bringing this back from the dead in hopes of a dyno sheet.

The Nissan world is severely lacking EFR info...

Hey Guys, sorry we fell off. We are a small business that has been extremely busy and growing!

The "EFR" series of turbo is a great turbo and delivered everything it was supposed to.

Pros: Total package. Turbo responds very well.

Cons: Slighty longer and bulky due to internal gate, at one time were tough to keep stocked. Nice price tag.

Ill have to bring the dyno graph from the shop. However the 62/58 made boost just a hair over 3k and pulled solid to redline. The power curve is very linear, boost transistions well and doesnt come on like a rocket but yet is a steady pull all the way through!
The car ended up making 367WHP @ 18psi but was limited to the internal gate at time of dyno. we still have a couple of efr's but have since been testing other setups as to accomidate our driver of the Boost Junkyz S14.(bigger power turbos etc) We will post some info and build pics of a efr powered 510 in the making here shortly.

If you guys have question please feel free to ask.

Thanks for replying

That's a great number for only 18psi! 400whp should be possible even out of the small EFR (6258) at 22-24psi. Do you happen to remember the torque?And when you say made boost a hair over 3k, I presume you mean it was at 18psi by then?

What larger turbos are you testing? Staying EFR and going 6758/7064? Or something other than EFR?
Lastly, any tips for fitting an EFR on an SR20? Aside from going top mount obviously...

Thanks again!
