Default upgrade to a 35R?

I read that a 35R turbo flows about 65lb/min, does anyone know an upgrade to it aside from FP HTA 3586?

my 35R has 1.06 exhaust housing right now, I wanna know what other turbos out there that flows more than 65lb/min and with a improved spool and dimensionally the same with a 35R single scroll turbo. thanks in advance

I can't use any v-band since I have Crawford 35R turbo kit, I'm just searching for possible upgrade for the regular single scroll 35R with more airflow and possibly billet compressor wheel.

cheapest option is the send my turbo to FP, but shipping cost is a killer, much better to just buy HTA3586 than ship my turbo there. I'm just curious if there are any other options

So you want a bigger turbo that flows more but spools faster at the same time?

I have the hta86 turbo on my setup and it not only spools faster than my 35r w/.82 it pulls much harder up top.I would highly recommend the upgarde.I plan on going to the track sunday I would let you know how it goes.

Get the HTA treatment or a Precision 6262. Precision also has the 6062 out, spools quicker than a 35R and makes more power.

hi thanks in advance that would be great
I read that the HTA86 flows around 75lb/min so a lot of potential power with it

is the Precision 6262 dimensionally compatible with the 35R single scroll? I mean I need the upgrade turbo to fit my UP, DP, IC piping. what is the flow rate of the 6262 turbo? I just read it makes huge power with fast spool but I really don't know what is the airflow, thanks for the advise

The 6262 wil bolt right in place of your 35r but flows just a little less than the hta86 thus thats why its a little cheaper and I think it uses precisions center cartridge instead of the garrett chra cehter cartridge.

What does the HTA do differently than a regular Garrett 35R?? How does is spool quicker AND make more power??

ALSO does anyone else do anything similar to FP because no matter how great it is I will never go back to FP for anything

the precision turbo 6262 is close to the fp unit and buschur offers a precision turbo of his specs called a fs635 thats close also.the hta86 turbo uses a special billet wheel that is 62mm inducer and 86mm exducer compared to the 35r cast wheel which is about 61mm inducer and 82mm exducer.the wheel flows over 10 more lbs per min and is lighter and more aerodynamic thats why it spools a little quicker and makes more power.

thanks a lot, that was very informative

looks like HTA 3586 will be in my car in the future when I have stand alone ecu (once I have the money) so I can go speed density tuning and maximize every gram of air the turbo can give

I so wish I went with the hta86 but I wanted better spool, so I did the hta3582r since I have the 1.06 A/R hot side as well. Figured that would already affect spool so I didn't want the bigger exducer on top of that. Either way, both turbos are good for mid 6-high 600's on q16. It's gonna be a fast car!

First was already answered. The 6262 is very similar to a FP86 but its a complete Precision turbo rather than a modified Garrett.

The 6262 is dimensionally similar to the 35R/HTA86.

I just checked buschur website, they have great turbo line up.

https://secure.buschurracing.com/cat...0749a7c08ade02

I saw this FP HTA BB turbo, it has great airflow, over 80lb/min. I checked FP website, didn't see it there, IDK if it's a custom specs for BR. I'm wondering if the 88mm compressor can be fitted to the HTA 3586 for more airflow, and w/o any problem at all.

The 35R turbine wouldnt be a good match for the HTA88, too much compressor, its pretty big too. You would just be better off getting a standard HTA88 turbo.

looks like HTA 3586 would be the best upgrade for me, I like the fact that the garret 35R BB turbo can operate without using BOV/BPV

You should still have a BOV/BPV of some sort. The anti surge housing doesnt eliminate the need for one.

Im not sure why they wouldnt, but its beneficial to have one. The valve prevents surge from damaging the compressor and bearing section. Without the valve you also lose response between shifts.

if I go stand alone ecu and do speed density then it would be safe for me to put BOV, but I don't know anyone or any shop here that can weld aluminum that well and reliable to put a BOV, I don't wanna have boost/vacuum leaks due to poor welding. it makes it much harder if you consider the fact that the IC pipe of Crawford is only 2in in diameter, unlike the other kits with bigger IC pipe diameter.

there are some shops who can do a good weld on stainless steel, but I still have to meet a very good welder/shop with aluminum.
