hta 71 OR hta 73
hta 71 OR hta 73
I'm trying to make 450 whp on e85. I love canyon driving sometimes, but find myself on the freeway quite a bit too.
I know that it can be done on either one of these turbo's, but which one would you take? I am concerned with longevity of motor.
I can buy a brand new 71 hta fully loaded for less than 1500, or a used 73 hta for 1300 on here. I am concerned buying something used but will consider it if the green is exponentially better than the white(71 hta).
PLEASE REMEMBER I AM NOT TALKING ABOUT THE OLD WHITE RABBIT, I AM TALKING ABOUT THE HTA 71 MADE IN FEBRUARY OF LAST YEAR.
Thanks for the help.

I don't get it. The green is like the most popular turbo for our cars and no one talks about the 71 hta. Is there something I'm missing here? Looks like a sic a$$ turb but I can only find a couple threads (niether of which compare and contrast the 71 vs 73).

71 will produce a more responsive 450whp.
73 will do it with more lag.
typically on e85 the 71 makes 470-490whp maxed out.
the 73 makes 520-600whp plus at max flow
from results on this board.

Recent thoughts between the two:
Will the 71 destroy my motor because of all of the low end torque that comes with it(on e85)?
Even though the green is bigger with more power potential, will the delayed torque keep my engine safe(r)?
Is it true that with lag comes safer torque? The only thing holding me back from the 71 is that I feel like all that low torque will blow my motor.

You do not have to run high boost at low RPM. With a proper tune you can avoid the big torque spike. The stock turbo has the same potential to throw a rod with a torque spike.
Understood thank you for the response. So now I'm thinking evo 9 turbo on e85 (slight inconvenience for e85) or a green on pump 91.
Which one will you guys think be safer for my motor? I feel like the e85 / 9 turbo combo would be a sweet *** street set up but I don't know if I'm up for driving 20 min. every time I need to fill up my car / gas canisters.

No one can tell you definitely which way is best for you - only you know that. Personally, I'm not the biggest fan of E85, nor is it all that convenient to find around my area. I have an HTA71 and absolutely love it but that comes with a caveat - being I have a IX, it only cost $650 to do it. If you have to pay $1500, I'd save just a little extra and get a Green. Mind you I don't really know the limits of 91 since I get 93 octane, but I have to imagine you can make a safe 91 tune that gets over 400 awhp, depending on your supporting mods.
If E85 is plentiful by you, just do that and the HTA 71. To get upwards of 400+ awhp on a IX turbo I believe you have to spin the heck out of it and you start to get out of it's ideal pressure island. That is why I went with the HTA71 - it makes a little more power pound for pound yet barely adds lag, if any at all. It's a great all-around turbo, especially for the goals you have in mind.

I personally would consider having the turbo upgraded by Map to an EF1. pretty much the same gains as the 71mm from FP. the upgrade costs $650 and they will even do evo 8 cores as well. the stock 16g goes flat at about 6500rpm. all the upgrades, original FP green, 20g, hta 71mm, fp white, BBK lite, EF1 will ALL make car pull hard to 8000rpm.

I found a 9 turbo for $200. Dude said he would give it to me installed for $500. I'm thinking that I'm just going to go this route and run e85. I hope that I am happy with the gains.
Not quite - any turbo, even a stock IX can bend a stock rod on a bad tune. You're actually less likely to do so on a 71 or 73 (or EF1, EF2, BBK Full, etc...) with proper boost control. Keep the torque under 390-400 ft-lbs and don't load it up in high gear at low RPM and you'll be fine. The 71 is a mild step up from a IX turbo but a pretty decent step up from an VIII 9.8 turbo. As the other poster said, if MAP will convert an VIII to an EF1, that's how I'd go, personally. Great turbos.
on e85 a 9 turbo upgrade is a waste of money. e85 runs so much cooler than gas the extra heat of 8 turbo blows over a 9 is not a problem. I wouldnt even worry about 9.8 hotside. Curt Brons 16g resords were set with 8 turbo and 9.8 hotside. spend the extra and get areal upgrade.
what everyone is tellimng you is no matter what turbo you go with on stock block it is advisable to keep torque below 400.

Update: Thanks for your opinions, I have decided that I just can't pass up this 9 turbo for $200. Along with performance comes longevity and I want my motor AND turbo to last for years to come without having to worry about rebuild. SO-I'm doing dual maps 91/e85 with the 9 turbo. I would be happy with around 375/375 dynojet on e85. Wish me luck.
