Yeah never thought I'd share that kind of stuff here but it's taking most my time and don't have much else to do lol but thank you guys a ton for the support!! That's awesome! But the VA is covering everything for me, which surprised the hell out of me... But thank god cyz is be screwed for sure!
I did check that ef4 out, looks badass! How's the reliability on that bish?

 

I have been beating on it since last feb with no issues other then getting my preload right. I mean I can post a graph for you if you want to see it, but keep in mind my tune is kinda deluted to keep tq down so the motor doesn't let go. I made 562 whp and theres plenty left in it, but being stock motor I didn't want to push it to much further.

 

No that's cool, I like your setup! 562 hp would be sweet if I hit that!! Have u heard much about those ATP turbos?

 

Don't bother with the HTA3582, if you are going that route just get the HTA3586, especially on a 2.3 engine. Way more potential with only a slight hit in spool up.

 

I'd rather keep the spool up, I should just pull the engine, sell everything and start over lol that would be sick to do, way above my pay grade but sounds like a challenge

 

I would contend that you stick with the stock frame options available to you, my friend.

 

Agreed.

 

Yea I agree, stock bottom end and keep torque down would be nice

 

I can build you a 500awhp for less

 

I'd let u too if you were closer lol

 

If you want low end torque, you have the wrong vehicle, get a muscle car. Well either that or put a dual charger system in it. Supercharger/turbo. Then you can run a 3586 and a supercharger for low end .

I personally don't stop light race or anything like that, so most of my driving is on back highways or drag racing at the track where spool up doesn't matter anyway. You will probably be happy with a 3582, that is what I have on my car now, but the non HTA kind. A 3586 upgrade is in my future, but not until the engine is built. Figure that will put the car around 600whp or so for a solid 10 second pass at the track.

If you are thinking about staying with the stock bottom end, that is what I have now and my torque is around 400-420 at 31.5psi with HKS 272 cams. I wouldn't go with a larger turbo than the 3582 if you are staying stock bottom end.

 

Hi Guys,

Why consider an EF4 over an EF3? An EF3 is rated to 550whp and would surely spool up faster (300-400 rpm slower than stock).

I'm ordering one for my JDM Evo 7 (same as an 8) stock block with Kelford 272, ID1000 injectors, 255LPH pump, large intercooler/piping and 3" TBE/O2 etc..

Expecting 450 WHP on pump at 28-29PSI and 500+ with Meth 32-24psi.

Seen any Dyno results for an EF4 ?

 

You do not need a 2.3L engine and an HTA3582 in order to make that power level. You can easily make it with a stock framed turbo on the stock bottom end and save yourself thousands of dollars. The reason why people are saying the EF4 is that it can achieve those numbers without all of the necessary supporting parts especially if you want to make them on pump gas. What parts do you currently have on the EVO? Here is a little something that I put together on the EF3 turbo:



 This EF3 is a damn good turbo!!!

 I'm really liking the results I've seen out of this turbocharger so far. I think this one may be MAP's big ticket into the turbo game.

 The off boost response almost makes it feel like a powerful NA.

 I love this powerband...stock turbo curve with the extra top end power we all want. I can only imagine what 30+ psi will look like.

 Mid 400whp is not too shabby with a stock-framed turbo on pump/93.

 Even on a stock 2.0 block the car never felt laggy and had amazing response out of the corners. In hindsight I’m very happy to have this turbo on my car , and after having experience with tuning , owning , and riding in BBK full , FP greens , reds , blacks , Gt30-35r , stock 9 turbo cars, I would choose this one before any of the above for my needs.

 Getsideways has an EF3 with stock block with which he placed 2nd at the latest GTA event and might have even given the first place finisher (Professional Awesome running an MAP EF4) a run for their money with some more seat time!

 NP. That would be easy on EF3 (this was reference to its ability to make 500whp on e85)

 My bolt on stock block car makes 46x WHP on the EF3 consistently time after time with ZERO internal work, STOCK MAF, Stock ECU 93 pump gas. I don’t see how it couldn’t crack 500whp on E85. This is at only 27 PSI at 7k. I’ve seen the turbo achieve 33 PSI at 7k in my car.

 The EF3 isn't much less than the EF4 flow wise although the wheel is a tad bigger. I have full confidence being that the EF3 should be just as powerful with e85. Not to include the EF3 spools faster as well.

 I hope you take my word on it that you will definitely like this turbo.

 As far as 500whp on an EF3 if we are talking Dynojet then I'm confident I've crushed that already making 478 on a MD. That was at only 23psi at 7K. I've since added a different fuel pump and 1450s and went from 28 to 34 at peak holding close to 30 at 7K so I expect to make well over 500 next trip to the mustang dyno which should equate to high 500s on a DJ maybe close to 600 stay tuned.

 PlanoEvo's EF3 beast is wicked. We were out bombing around in it earlier this week and you really feel the acceleration in the pit of your stomach!

 Ended up making 465whp at "only" 25.5 psi up top this time but ran out of fuel control. Time for rewire, etc. Still on stock FMIC / IC pipes / intake manifold / exh manifold. This is easily a 500whp+ turbo on a proper mustang dyno with a proper build and boost.

 What will be more fantastic is when it’s tuned and you just hit the accelerator and you get that big *** grin from ear to ear then you know it was money well spent.

 As of today the car feels great it drives great and from what I have seen it is very capable of making 500/500.

 Yea I have no doubt this will do 500+ easily once it's more sorted out and has a real WGA on the car.

 The EF3 is going to be one hell of a turbo.

 I would say the car feels like a stock 2.0 EVO with a stock turbo but makes about 200 more wheel horsepower.

 Oh, and I heard this guy take off down the street and the EF3 with the anti-surge sounds very similar to a BB turbo...very cool.

 Theoretically, it is my humble opinion that an EF3 powered car with a fully built 2.4l and every supporting mod imaginable could knock out ~610whp if they chose to disobey our recommended operating range. This is completely theoretical of course.

 I completely agree with you. I’ve seen this thing at 32 PSI at 7000 RPM on my motor. Currently it’s at 27 at 7000. I’m very confident that even on my car 540+ is possible.

 The trend with the EF3 is that it loves to keep making top end power. 550 hp 500trq would be more likely.

 My best guess would be 60-61lbs/min on the EF3. The EF3 has a bit larger comp wheel than the HTA Green.

 And trading or selling your GT35r to make it happen is even more proof that these turbos are outstanding.

 I'm running ~465whp with an EF3 at the moment (albeit on E70) but in regards to the well-being of your bottom end I think you'll be just fine. (Chris Carey on stock motor)

 Go EF3 you won’t look back!

 The Full Blown 340 pump seems to be a great match for the EF3 on E85.

 Then I’d do EF3 all the way. Trust me you'd have an erection all day long.

 I know Getsideways has a built motor with his EF3 and it’s a monster.

 The EF3 is a very nice well-rounded turbo for the street.

 That is where I was going with when I said "fatter powerband" on the EF3. Sure the EF4 might get a person to their magical 500whp goal on stock block, but the EF3 could be faster all over still even with keeping the torque lower yet as the powerband is better.

 If you want that 500whp/400tq and that’s your goal period then go with the EF3 you will not be disappointed trust me.

 Now imagine if you had a built motor you'd have the motor supplying it as well I bet the EF3 with a built motor could do 600/525tq no problem.

 EF3 is the best option for a stock block if you aren’t exclusively a drag racer. Even then on the stock block it’s not far off. If I had to do it again on the stock block I would stay EF3. It’s a better all-around turbo and still is ''laggy enough'' to make tremendous power on the stock block while being very responsive.

 EF3 should have plenty for most everything along with wicked street response.

 Good luck on your build. Good choice on the EF3 makes me smile every time I’m in the car!

 I am glad that you see the awesome benefit of selecting either turbo. Personally, I am a fan of the EF3 which is why it is sitting in my garage looking pretty.

 EF3 is right in between the red and black as far as top end power and nearly identical to the red in spool up which puts it ahead of both the BBK Full and Green by a fair margin in flow numbers.

 It seems the EF3 at this point has been the MVP of their lineup IMO.

 I really like the turbo a lot. It is a little laggier than my previous EVO 9 turbo but for the size and power it makes it’s not bad at all. I love it.

 On my 2.0L LR it is hitting about 21-22psi right at 4000rpm.

 The EF3 on a 2.4 feels better than a stock turbo on a 2.0 BY FAR. Third gear and fairly positive boost in the 2500-3000 is odd feeling (in a good way).

 

My Parts:

Stock 2.0 block with Kelford 272, ID1000 injectors, 255LPH pump, large intercooler/piping and 3" TBE/O2 etc..

The car is a street car, not for competition work - but 500 WHP on stock block is the target and the least lag, giving the most power possible in the 4000->7500 range.

So what are you suggesting is the best option - EF3/4 are both stock frame. I could get close with a bolt n TD06SL2R-20G for 1/2 the price of an EF3/4 and get around 430WHP max - but thats what most people do..

The question is though is could an EF4 make 500WHP without meth with my mods, expecting intake temps/backpressure to be lower but is it really an option for a street car.

An EF3 would make it with meth, but thats another $1000 plus buying meth regularly but would probably be the nicest to drive, being more responsive.

Thoughts?

 

I strongly advise to go a diff path than a 35r. You can easily make that power on that size of turbo, but youll have lag and it wont be too much fun. An FP red or black can easily make 500+ and it will be ALOT more fun to drve. Stock block, FP red or black and some S2 cams... good tune and your good to go. Much more fun then a laggy 3582.
