No problems with cracking or leaking with that setup? I'd be concerned about the amount of leverage produced by the engine vibrating a mass of solid fittings that far outboard, with nothing to dampen it.
 
Hey guys I don't know if any of you remember the build I had going on but the car is coming along good still. I really need some help picking injectors though. The car will be running on 110 fuel and are hopefully going to run at least 35psi so please guide me in the right direction. Here is a summarized mods list.

Any other concerns with this setup?

Engine:
4g63 block, ARP head studs and main studs
Arias 8.7:1 pistons
Eagle 4340 rods
Stock polished crank

Head:
HKS 272 cams
Crower springs and titanium retainers
3g lifters
Ported and polished head
HKS cam gears

Intake:
JMF drag manifold
75mm BBK throttle body
Air to water intercooler setup

Fuel:
RCI 12 gallon fuel cell
-8 AN feed and return
Bosch 044 fuel pump
HKS fuel rail
Injectors ????

Turbo and exhaust:
HX40 6 blade with twin scroll 18cm housing
Top mount twin scroll manifold
Dual tial 38mm wastegates
3.5" bumper exit downpipe

Cooling:
Aluminum civic half radiator


Misc:
DSM link
Around 2600lbs
All solid mounts
4 bolt lsd rear
ACT2900 for now
Fidanza flywheel.
 
We're running 1200's on VP110 in Dave's car, possibly stepping up to Q16 soon. Currently at 30psi with the HX40 we're seeing around 60% duty cycles, which I'm sure will go up as the boost climbs.

If you have Link I see no reason not to run at least 1200's, possibly 1600's if you can get a good deal on them somewhere.

I have no leaking. Ive been on city streets (bumpy), been through monster thunder storms, and speed of up to 90 MPH for the past 600 miles that I've had this setup and no issues. My car is also lowered 1.3 inches with the Prokit....

You want simple? Go install a 14b, no need for a gauge. :sneaky:

But seriously, it's not that hard to do.

Nice. Thanks for the help. Any more info on that car?

Sure....when it's not running 10's it likes to break driveshafts. LOL

I'm sure you don't have to have 30 fittings just for one oil pessure gauge ill figure it out thanks anyway.
 
And I'm sure you don't need a functioning Holset.

Good luck.

I didn't know the more complicated my oil pressure gauge set up was the better my turbo worked. That's news to me. Ill post up pics when I'm done with my gauge setup.

Who said anything about a complicated gauge benefiting a turbo? I used my fittings because I trust my suppiler (ExtremePSI) in a FAST shipment rather than the other supplier, JEGS, which is located in OHIO. Ive had stuff from them and they took forever. Do what you want, that's the cool thing about having freedom. All I did was depict what I did to my setup WHICH WORKS. I never tried to shove my idea down anybody's throat. Most posts on here are people demonstrating what they've doing with their cars anyway. Hell, this entire site is based on DIYers and we wouln't have Holset turbos on DSMs if it wasn't for that. Let's not fill this thread full of nonsense. If you don't like the idea for any reason, then simply don't utilize it. No hard feelings.

Im sure your setup works great but you did over complicate things a little bit. All I did was separate my oil line and place this in-between them.

JEGS Fuel Pressure Gauge In-Line Adapter Fittings - JEGS

As stated above, I dont deal with JEGS much because their shipping service isn't as great as Extreme. Oh and my idea as well as the guy who posted your link has been shown in this thread earlier. Why would I help out nfernotalon even more by posting the JEGS link again since he didnt even bother to read the previous pages to notice that my idea had already been posted as well as the one with the JEGS fittings? Dont take it as I'm bashing you.
Oh and you can't get easier than that JEGS fitting for a gauge. Good find.

I wasn't insulting you or your setup all I asked was for was a simpler way of doing it Ididn't say yours didn't work. As for reading through the thread I've been. following up since the holset thing started. I'm not sure how I missed the jegs link but thanks for posting it back up its exactly what I wanted.

Not at all just wanted to make it easier for him and others to find. Do agree with extremepsi being far better at shipping.
 
what do you guys think of a HX35 or HX40 in a T3 flanged .63AR housing non wastgated housing?

i have been spitballing with my local turbo shop about good setup with an hx35 thats affordable as well

im pretty sure this is what im going to try out next i might even get a free one (or really cheap) and have the car dyno'ed to see what a Hx35 can really do in this .63 ar housing

what do you guys think?

I have a 1.32 divided T3 I'd like to try. ;) I PM'd you on the Link forums.

Are you guys mating Garrett Turbine Housings to Holset CHRA's?
I have a Divided T3 16cm^2 Holset hotside I'm gonna try out with my 7-Blade HX35.

Running one of those new Garrett Divided T3 1.06 A/R units on a HX35 or 40 for that matter would :rocks:

I have the OEM 12cm^2 housing I can reverse engineer.
If necessary, I can have the housing sectioned so I can precisely reverse engineer the dimensional requirements for the HX35 CHRA.
In fact, I think I'll do that.
I've seen the aftermarket Holset Divided T3 Housings, and they're crap castings.
I've heard the new Garrett Housings are casted really nice.
They are $400 though.

It'll take a lot of machining, but if you're getting the housing for free then you have some money to spend.

actually it wont take much machining at all as ive held these in my hands and the .63 housing is real close to the hx35 wheel, and as far as cost with a rebuilt complete hx35 or hx40 we are talking about $550-600 for a pretty much brand new turbo, and i might even be able to get him to throw in the 4 bolt flange for the exducer LOL

i figure that a .63 housing will be able to max out the hx35 to its 60lbs min since its a tad larger then the BEP bolt on. and for an hx40 we can get a larger A/R

what do you guy think the best size housings would be for each holset


also for the price do you guys think its a good deal?

What your eyes may not tell you is the depths are probably completely different....as in the Holset turbo may fit into the Garrett housing further, or not as far as the Garrett turbo did.

Make sure you measure, and remeasure when you're ready to machine the housing. Screwing up the machining will ruin the turbo.

Yeah i understand i wont be doing the machining any how. the turbo place will be doing everything... we were even talking about building one and them having it dynoed with my car being the test car and likely taking it to roadrace eng to get some real results on their dyno this might take a couple months to get all this done but i think it could be a great T3 Holset solution
