So my 35r has a blown exhaust wheel and its going to cost me $900 to rebuild it. Its going to cost me over $2100 to get a HTA by the time you add the cost of shipping and tax.

Obviously if i was in the US i would jump at the HTA no questions, but im not sure if its going to be worth the extra expense for me.

So my question is to those that have had the regular 35r and have swapped to the HTA, do you think i should bother with it? How noticable is the difference? Has anyone done back to back testing on pump gas?

thanks

 

I've swapped back to back. I didn't notice the difference by feel.

Think of it... a 35R makes like 700 hp on race fuel, and if you have a stroker your probably making over 600 ft/lbs of torque. Now Dave Buschur has said a 35R adds no top end, but 35 atw hp and torque in the mid range.

So are you gonna feel an extra 30 hp or torque at the 700 / 600 level?

 

Its not just the power man, It's suppose to provide way better spool up and more power in lower rpms making it more effiecent

 

You say, "way better spool up"? How much you think? If I recall Dave said 200-300 rpm but I'm not sure. And this was with .82 A/R turbine housing. Your mileage may vary.

Here is how well an HTA spools on a 2 litre from Dave's recent posting of tuning his RS.

 

It all depends on what kind of driving/racing you will be doing. If your into Autocross or Road Racing this turbo would be worth the extra cost. If your not into downshifting all of the time, or you plan on running a stroker which operates at lower rpms it would be worth it as well.

 

subscribed, i'm trying to decide between the two (gt35r and hta35r). i don't road race and i don't mind downshifting lol

 

Most people run the 35R with a .63 A/R turbine housing. Do we know the spoolup differences from a normal 35R to HTA with this turbine housing? The answer is we don't have this data, so to act like the spool difference is huge is inaccurate. To act like it's not their is also equally inaccurate. It's a bit of unknown.

I did do the swap, but I did not datalog a pull before the swap, and after, to see the exact difference. But I did not notice it. Seriously would you notice a 200 rpm diff in spool? If it is that even?

 

if you are starting from nothing i think it is worth going with the hta, but if you need to buy one i would spend the extra for the hta, i would love to see a hta on a dsm, is your evo a 6 bolt of 7 bolt?

 

where are u buying a hta35r for $2100, thats a lot,

$1699, $401 for tax and shipping??????

 

He's in Australia. Shipping and different tax laws.

 

yes i agree with you there, for road racing and autocross you want all the response you can get. I use my car for mostly street, so if the difference isnt that noticable its probably not worth it. I wont be running a stroker, just a built 2L. Im trying to get a solid powerband from 5500 - 9500 rpm.
Your evo sounds like a weapon, got any more info, pics?

What A/R are you using? Im running the 1.06 at the moment but i'm swapping to the 0.82. I wouldnt recomend the 1.06 for anything but a drag car.

all EVO's are 7 bolt as far as i know?

$1700US = $1852AU + at least $200 for shipping then you get stung with 10% tax on top of that

Yeah i see what you mean, the extra midrange would be nice but if its not all that noticable its probably not worth the hassle for me.

cheers guys

 

I love how someone who's done the 35R to HTA35R swap and felt no SOTP difference gets shot down in favor of believing the EvoM hype.

 

wheres he getting shot down?
