I don't think anyone has said the EF2 makes more top end and I would be surprised to hear people think that.
The FPgreen is a bigger turbo, its laggier and has more top end. The EF2 for a quick response turbo has most of the bang for less lag.
The stock frame turbo world is simple...if you want more power you get more lag. I haven't seen much at all to show that people can magically make more power with one vs another without sacrificing something. It's all about balance in the stock frame world imo.

Kracka that power curve and spool up looks amazing
Looks like the EF2 is treating you great.

What kind of numbers did you see on the BBX Lite after the supporting bolt ons were added? I'm torn between the EF2 and the BBX. If you have a build thread I'd love to check it out!

Looks like the EF2 is treating you great.The EF2 seems to be making a solid 60-80 more WTQ at 3k vs the BBX-Lite and its top-end gains are very similar, and in some cases better. I also think that has a little to do with Kracka's porting, but regardless they should be very close.

I was having the same debate, between the Lite and EF2. I'm going to be purchasing the EF2; it spools nicer, and makes similar top-end power. I'll take a little less top-end power, in exchange for near stock spool.

I don't really understand why people are so concerned with figures like that. That wtq at 3k rpm is achieved by flooring the car at 2k rpms. Why the hell would you ever do that on the street? Downshift into 2nd

^Figures like that determine response on the street and in DD. It's all good to say things like "just downshift" and wait for the power but that's a mindset for the track. When your merging on the freeway you want the power to come in as soon as possible. I can't drive around at 4000 rpm in heavy traffic all the time.
Most turbos on the market are just marketing driven peak number deals, the ultimate turbo for the street is determined by it's general performance curve.

Ah thanks, I thought he had the Lite, and yes your right that'd be more in line with the EF3

Like mentioned before, I like to keep it as streetable as possible. I don't want to have to downshift everytime I feel the need to pass on the highway in 5th, I like how I can lean into a bit and that 280 ft-lbs gets me easily past another car. Since 3k is what I'm normally cruising at its nice to have the power on command. Not to mention in traffic if you ever need to avoid someone from hitting you, you'll easily have the power on tap to get out of the way.
Plus why want more lag for nearly the same top-end, doesn't make sense to me for a car that will be on the street 99% of its life.

Looks like the EF2 is treating you great.As rmondo stated, I have the BBX not BBX Lite. IMHO If you are on stock block and intend to stay that way the BBX Lite or EF2 are the turbos to get. Search for posts by me in the dyno section here to see gains I've had at various stages, I won't clutter this thread.
