I came across this http://www.turbotalk.org/bb/viewtopi...11070fe069563d

I would have already put on a vgt if it wasnt for a such a space issue. the only way i see that happening is a top mount and some kind of short runner on my car.

For all the garrett snobs out there, the wheel size on my hx30 is between a 2871 and a 2876.

yeahh that is a nice setup but hard to find hx30, where did you got it?

[Dave926]

Ebay, freshly rebuilt for 250 bucks. Came with the high pressure holset actuator for some shenanigans later on.

Not a c-hair of shaft play either. They are tough to find, I know they were used on Case tractors, and I think the 4bt cummins from the frito lay trucks. Mine also has an anti-surge housing as well.

is that dayly driven vehicle,how is the low down torque and how quick does is pickup when downshifting,like when you try to pass a semi on the highway?

[Nasty Vr6]

I'm building my kit now i want to run a hx 35 but the internal wastegate is set for 25psi and I'm planning on only running 7 or 8 to start off with. People say that you can wield the cup part of the wastegate shut ao you can run a external one but the whole is so small you might get boost creep?? What would I be able to do to run lower boost?

[wabbitGTl]

i will be running an hx 30w on my car. I used a saab internal wastegate actuator with an extended eyelet rod that will let me use it the internal wastegate

from the first page.

anyone have a final word on the oil feed restrictor, namely for a vr6?

[Quintin@USRT]

so ummm...ran across a deal for a 7-blade HX35 for $120 in philly...picked it up tonight....oh its on bitchz! 8blade=52lb/min, 7blade=60lb/min

...so i guess you gave up on the spa turbo setup?

[Quintin@USRT]

no they're just going through a complete design change and wont have a 550~600bhp capable turbo to give me til november. So until then i need something to play with.

You really need to know what kind of pressure your motor makes before you slap a restrictor on there. The oils specs are posted on the first page.

Mine isn't running yet with the hx30, almost though.

[Sparknock]

i have a he351ve itook apart so you guys could see how it works
and i has the same compressor wheel as the he351cw

[Quintin@USRT]

ok so this 7blade HX35 has some odd measurements... a 54mm inducer and a 76mm exducer...i thought it would be the same as the 8blade (56mm inducer/ 82mm exducer) with one less blade...can anyone else confirm the size of the 7blade? googling just shows a bunch of copy/pasted info saying it should be 56mm but no real confirmation.

[Sparknock]

my buddy has a 7 blade 35 i will see if he will let me messure it.

[Dave926]

Sparknock there is a ton of info out there on that turbo. Afew sites like turbotalk.org, realhomemadeturbo.com are just afew sites. On rhmt there istalk of using arduino and ms to run a pwm table adjust the a/r side of the turbo for maximizing bspool and efficiency. I really suggest you check them out.

yeah thats cool. would like to see some one get the VE working with the smart module on it. i have seen a VGT just like the one i have using a waste gate accuator like the vnt. worked well on the ISB cummins motor. i think they said it was hitting 25-28 psi by like 1800 rpms or so. i wonder if this mod was done could it be just as effective on a gas motor.

yea that would be nice.

Best price I've EVER seen. I wanted to wait another couple months but couldn't pass it up. They usually sell for twice as much or more.

That and I lined me up a local second-hand supercharger off of a gt, once he gets the 4L whipple on there.

[Dave926]

Sparknock just go on turbotalk.org, realhomemadeturbo.com or homemadeturbo.com and search for user "aero"

His is on a 2g dsm, running a 14b actuator to control the vgt and a tial to limit max boost. He was seeing ridiculous boost pressure under 3k.....how many 500whp turbos can do that?

EDIT: this is the thread you may want to investigate http://www.turbotalk.org/bb/viewtopic.php?f=25&t=4

Your ****ing nuts to run anything that big. high spool that hits hard enough to feel like you got hit by a cement truck...thats full

[Pat @ Pitt Soundworks]

PSH it's just a gt42R. With both the supercharger and the turbo it should be fairly manageable

[16v lover]

just got to test drive my 16v with a he351cw i get full boost (20psi) by 4k in 2nd gear and it comes on so fast its not even funny.

did you ever get a chance to measure the wheel on that?

[Nasty Vr6]

So what do you do if you wanna run 8-10 pounds?

[ricky_vwt]

External wastegate set to 8-10psi.

[16v lover]

Quintin do you want the turbine wheel measurement or compressor wheel? i had to change out the rad cuz the end tank dident want to live anymore so its back in the shop and i could pull the DP off to measure the small end of the wheel if you want.

compressor

[Nasty Vr6]

External wastegate set to 8-10psi.

And what do you do with the internal one, people say that you might get boost creep.

[Quintin@USRT]

weld it shut.

[wabbitGTl]

if you're really concerned about it, you can always buy a non-wastegated exhaust housing. i can't remember where I found them, but they were close to $200 new. just a lil fyi...

[16v lover]

Quintin. the inducer of my he351cw compressor is 61.20mm wall to wall if that helps you any.

[frescoG60]

How well does the HX35 fit the VR6's characteristics?

[Pat @ Pitt Soundworks]

going to need something bigger than 3"

Pretty interesting thread on a g6o with an 8v head. 280whp on 24 psi. I still have the stock holset actuator as well so i will be there at some point, and I should see over 300 whp with my 16v head.

[Dave926]

check my build thread, granted it hasnt been updated in a while. You can use another wastegate actuator from another car that has an adjustable rod and go from there. I got mine from a Saab 900 with a t25, and got a metric eyelet rod from ebay.

I think its set for about 8si. If it doesnt work then tial and screamer pipe ftmfw

On a second note I just got some extra v-band rings so i can have a nice open exhaust for H20
