Stock turbo vs hta71 evom mods#

They have not shown to have any longevity problems, and power is power. Saying that these are cheap-ass turbos is, IMHO, ignorance. A $2500 turbo better have more area under the graph. But trying to compare a $2500 turbo to a $1200 turbo is kinda silly. I agree with you that a turbo costing 2x as much with a ball bearing center section, billet whels, etc will be (and damn well should be) better.

You will not and cannot believe your eyes at that moment.īut when you talk to the guy that just killed you massively, and start thinking for yourself in stead of following main stream mods that fit your car, but actually do not suit the engineĪnd to my opinion that's what the HTA71 is and will be, just another mainstream 71mm compressor turbo. Till the moment somebody with a quality built lines up, hits the throttle, and just rockets off. Topend is most probably the same, but the area under the graph is unequalled.Ī good turbo doesn't come cheap, and the initial feeling with a fresh mounted HTA71 will be freaking awesome, I know that, i've done that I do not say my setup is better than an HTA71, I just would like to point out that there is power and power. Yes I stepped down in size, caise my priority was spool, respons, and early torque. The respons is awesome, pushing all this air through the std Sti 08 Tmic. I'm running a MDX321T in stock location from Lateral Performance (Turbo Dynamics) which is a hybrid GT3071, with a 68mm billet compressor wheel, and the hotside untouched (only IWG) Result 400Nm/2400rpm 600Nm/3000rpm, 685Nm(500ftlbs) 3250rpm and 430hp from 4200rpm till redline (on a built Cosworth Motor 8,6 CR with std heads). In the end, when everything matches inside the engine, you will push either bigger numbers, or can step down in compressor size to keep same numbers but gain in spool and response.įor what it's worth, a little info on my setup (08Sti) Your AIT will go down drastically, which will able you to push timing more. Now if you take a decent -non cheap ass turbo-, with a proper hotside (10cm or bigger), and super fancy BB, billet compressor, you will notice you need MUCH less boost for same output (or even more output) and much more toppower. A 71mm compressor should do ca 430hp, and that's just what it does. Because it's all about the pub-numbers.but it performance for what you pay for it, but do not expect miracles. It fooks with the engine's VE due to the small hotside, so you have to run high boost. it's just another 71mm compressor with a to small hotside, that comes relatively cheap and will do for 95% of the scooby community that's working in the powerlevels the hta71 could deliver. Off course the HTA71 is a hype to be, it's just a reasonable priced turbo that pushes good torque and power. Your experece with the HTA68 (arguably their most controversial turbo) shouldn't define them as a company or the products they build. However, the HTA71 is an excellent turbo and my car is a stellar example of that.įP turbos have been working well in this segment for years, the sucess of the Green, Red, Black, etc shows that they make good turbos that work well.

I'm sorry that you had issues with getting it to work for your particular application. I say it works because of my graph and results.īesides, this thread is about the HTA71, not the HTA68. My turbo works great, excellent boost response (better than any other similar sized turbo i have tried) and it makes great power for it's size. Making over 400+ whp and being responsive = works. I have more power everywhere (+100 whp more on top, +20 lbs tq down low), get to peak boost several 100 RPM faster, and there is not much lag off of boost in cursing situations whereas sometime the FP sometimes would not hit the target boost. I know it isn't exactly the same, but I provide it as a counter point. I have a stroked ej205, so my build may be non-standard, but with my rotated Garrett gtx3071r, the drivability is night an day. Makes 330 whp and sucks most of the time while driving != works to me. If I was already cruising a med RPM and then wanted to accelerate it would take for ever to get to my target boost, normally in time to shift. Without the 10 cm^2 hotside, that turbo caused a huge restriction. MPS got it to 'work' for me and got about 330 whp using the Blouch 10 cm^2 hotside on pump gas, but it was still a laggy turd.
