Very impressed! One pull went as high as 328whp 294tq on 20.5 psi but we dialed it back down for longevity and sti top mount intercooler.

It works very nicely, slightly more then VF3x power with 2-3 degrees less advance needed up top. Smooth sailing - no feedback no fine learning anywhere. Most VF3x 2.0L make 285whp on this sheet at this boost level for reference.

Wow nice numbers!!

[fearnoevo]

Wow would realy like to see the difference in the 2.5. But those are nice #

[jwebsta32]

more TQ on the 2.5 for sure

[fearnoevo]

Suby power ftw

What do you think you could squeeze out with UEL headers, ej207 and a 8k redline?


This is actually the set up I plan on running :)

and a FMIC and you mean GT SPEC header up pipe combo.

Forgive me, but what kind of dyno were these numbers from?

[Bu11dogg2]

Yes Justin

he mentioned a dynapack 4wd dyno in a different thread. but it may be something different. dont know..



bren: awesome #s! this is kind of similar to what I hope my swap will look like when everything is finally done.. now I cant wait!

:munch:

[Berge56]

That 2.0 is one of the freaks that puts down high numbers! :lol:

Nice job bren!

With a fmic and headers you could see another 20hp and a longggggg powerband with this turbo.

I'd go even bigger like a green for the EJ207.

Road dyno. His charts read ~10hp lower than ESP's mustang

Just curious because I ran this turbo for a brief time on my 2.0 with very different results, don't have the chart though.

I'm open for discussion if you want to share your results.

There are alot of mixed results on these turbos, I've done a few.

They breathe pretty well and the ones I've seen on the stock airbox made significantly less power up top.

[yaya]

Part of my issue was airflow, even with a APS short ram my MAF was maxed. The other part may have been my bearing that was on it's way out.

But with significantly more mods and a built bottom end I could still only make 260hp/250tq.

The most stable results I've seen from this turbo have been on the 2.5. On the 2.0, I've seen more misses than hits so it's nice to see it work well for someone.

I had a hard time making power on this car (280whp range) with the stock airbox and an old filter. We also had a crappy bov on there though. Once we swapped it for the bigger APS unit and dialed it in it was like a whole different car.

It essentially shouldn't make less power then your VF setup, so it was possibly something else was a miss. Especially maxing a maf at 260whp.

[yaya]

Yeah, I picked up 10hp and lost 20tq compared to my vf34 setup with STI TMIC and IWG.

I really think it may have been the issue with my motor/bearing. If I hadn't had such low numbers I'd probably still be rocking the 68HTA.

I'll check out your build thread.

I'm thinking you probably had low compression motor at the time.

Nice tune bren :up:
