MAP EF4 e85 built 2L tuned by tscompusa/vr-speed
when I do a build I set a HP goal. nothing more nothing less is really needed. then I choose the best turbo for the job. because I want the broadest power band possible for the setup. this will give you the fastest drag car. the fastest street car. the fastest autocross car. the most fun for your money. why would you want to settle for anything less? I know I dont.
Jerry makes some very valid points. For the cost of these stock replacement turbos there isnt a big price cut on high horsepower setups. At that point you just need to look at what setup has the best powerband for the power goal. If the turbine housing is such a huge problem why use it? Then adding tubular manifolds and FF mani's for stock replacement turbos kills the whole draw. Now if it is a budget thing than I understand because I am on a tight budget so whatever is affordable is what I am doing. I may not have an optimal setup but it is what I can afford. So I may want something better but cant have it I will admit it isnt optimal and not act like it is perfect.

Good debate. For the most part. Lol. I am going from stock block and ported BBK full to MAP 2.3\EF4 next week. Do I expect the same low end torque and spool as my BBK? Of course not. But over 500 HP as the car sits today I have reached max potential and am upgrading. IMO, for the money there is no better stock frame turbo for a DD\weekend trips to the strip. To call this turbo a "turd" is ignorant and I commend MAP for defending its product and sharing actual customer feedback. Look for my official dynosheet\review in the coming weeks.

Lets not bring Dave's comments into this thread as I feel it would seriously derail it more (nothing against him or anyone else in here). This thread needs to get back on topic. No more bickering.
Chris was saying OP's car on pg 12, you werent talking about OP tho you were talking about my cars data
And alright how bout this, Ill get S1's, a stock ported intake manifold, and a stock ported exhaust manifold on my car with a 2.5" exhaust so we can see 500wtq off idle
BTW the knock was likely a fluke, Ive done several pulls logging since that log and I have 0 knock across the board and the tune hasnt changed.

Sven, just curious but why did you go with a stock replacement turbo then buy a manifold for it? Was it a piece by piece assembly or did you buy it all at the same time? Why did you choose that over a t3? These answers from an actual EF4 user would be nice insight.
It was sort of piece by piece. My stock motor blew in like early April of 2010, unexpectedly too...if thats possible for an evo lol. So I wasnt really financially ready to go ***** out since I was 20 and only working part time plus going to school full time. I wasnt really pushing the blocks' power limits either, car was making like 390/390. When the motor blew, I called Buschur for a motor and a build and I went with an FP Black since it was a much cheaper route at the time to just do a stock ported manifold with it, rather than spend $4500ish on a T3 kit.
I got the car back from Buschur a few months later in August and then my head blew 3 weeks after getting it home from some wicked detonation. At that point, I had the money to go a little further with everything so I decided I wanted to push a stock appearing setup, so I bought the ToxicFab manifold, had a fresh turbo from FP, decided to sell it, then got the EF4.
At this point, once I reach my goal with the car how it is now, I will be going with a 3794 or 6766. Not looking to break any records or anything, just want to have some fun.

You forgot to mention you ran the FP black and it didn't meet your goals, if I'm not mistaken?
LOL yes. The fact that the gearing in the evos is so short really numbs the feeling of lag, its there for a second and then the whole gear passes by in the blink of an eye. Ill be ok with making 800-900whp, even if it means not seeing 300wtq till 4300rpms lol.
