Holset HX35 build thread......

[kentuckyslider]

the gold nipple is where the line for the waste gate should come from.

tatertuner, thanx for the help, but I do understand how a WG works. I used the brass nipple that you pointed out for my pressure source and it was over boosting like crazy and the gate wouldn't open. When I got home today I removed the nipple to see what was up and apparently the truck it came off of was running 35-40psi because this is what it had feeding the stock internal WG actuator... I replaced it with a regular 1/4" nipple and the gate opened around 11-12psi. I am currently running 15psi with this setup... My afr is in the 10.4 range with the greater mass of air from the larger turbo going through my cobra MAF. I will be installing the intake and raising the boost until I run out of fuel on 110 race gas within the next week. The HX35 at 15psi would be very close to my GT2871R at 21psi if it wasn't running so fat. I could lean it out with my SAFC-2 but I think I'll just raise the boost!!!

[idahotuner]

haha i see looks liek waht you did should work good.

[masterdisaster]

dammit... just can'T wait for the dyno results lool !

Nice build, i'm glad you linked it to the holset thread. Hope the holset delivers the 450whp your looking for, I believe it will. Switching over to a holset has been one of the best decisions i've made since i started messing around with boost. The only way i would leave holset would be if i got a killer deal on a BW turbo, their extended tip technology is awsome. I will be checking in for some dyno results tomorrow.

Best of luck to you-Nelson

Nice build, i'm glad you linked it to the holset thread.

Yup, I don't venture over here to often. I wish the KA had a intake option like that one. Looks like a nice piece...hows the quality up close?

I'm sure you'll have pretty good results with that cast exhaust mani as well. The log types on the KA are good for close to 500. I've been debating on getting a cast type and seeing how the Holset matches up on the KA. Looks nice or the ole SR

Are you going to use alcohol injection? If not, you should. Better and cheaper then C16 and available on demand for daily driving situations

The casting on the mani looks just as good as the greddy that I've seen. It is the ISIS from enjuku racing. They rave about the quality of all of ISIS products. It all looks like regular ebay crap but Enjuku's tech guy said it is much higher quality. I am putting the intake on tomorrow and switching my 3.91 J30 rear back out to my 4.36 skyline rear. I tried the 3.91 in the 1/4 last November for a little more mph and it killed my 60' by .2 of a second. The Holset needs the lower gear to launch at the track. I am now scheduled for the dyno Thursday the 12th. I will post it up by next Friday along with my new times in the 1/8th.

[WDRacing]

I'd keep the 3.9 for highway driving and get a 50 shot

[kentuckyslider]

I only put about 3K miles a year on the car and I'm going back to the 4.36 R&P because it's much more fun to drive. Would you recommend a 2 step or a 50 shot(or both ) for launching at the track???

[WDRacing]

Well if the 2 step can allow you to launch on boost and maintain traction then thats the way to go. But N2O is easy as well...set the 2 step to the max rpm you can get and still have traction. That way you're not on the rev limiter building boost. More of a stomp it, wait .5 secs then launch.

But both need the 2 step so...start there and press on. If you can get lots of traction then drop a 50 shot in FTMFW. Cutting quick lights and nailing low 60's are the key to winning and netting good times.

I look forward to the dyno results.

[kentuckyslider]

Sorry guys but I'm going to have to push the dyno back AGAIN. I am starting to get the slightest bit of shaft play and I've decided to rebuiild the turbo for $150 before I go any further and damange a wheel. Obviously with the restrictor it had in the pressure feed line it was ran at 40psi on the truck it came off of so I think it is a good idea. I will have $400 in it with a fresh rebuild with a OEM Holset rebuild kit done buy a DSM guy. I'm also rebuilding my starter while my intake is off and I'm hoping to have it back on the road and ready for the dyno in 2 weeks. So look for the dyno results by the end of the month.

oh yeah, I got it up to 22psi and it's a beast with 10.8-11.2 afr's. It idles perfect and the JWT tune is doing just fine at that boost level on 93. I'm thinking at least 450whp(25-28psi) on 110 sunoco before I need bigger injectors. I can't wait but I'm trying to do it right the 1st time.

[BOOSTFOOL]

what kind of spool are you getting with a holset?

[nelson8708]

Got my car running today and it is going to be a beast. I did a 3rd gear pull and it hit well over 20psi and scared the crap out of me. It spools just as fast if not faster than my GT2871R(i know that sounds impossible but it does).

What are u doing for oilfeed lines ? do u have the sizes

[kentuckyslider]

What are u doing for oilfeed lines ? do u have the sizes

I've gat a banjo to -4an conversion fitting off my stock oil feed location going into 24" earls SS braided line with a 90 deg end. This goes to an earls 12mmx1.5 -4an fitting that threads into the turbo. My rebuilder installed a holley card jet for a restrictor while my turbo is being rebuilt. I got my banjo to -4an adapter from ebay and my earls parts from summit. I also have a T3 oil drain fitting going into a -12an earls braided line for oil drain.

[Logan76]

what size hole on the restrictor?

[masterdisaster]

it's been 2 weeks!! dyno results??

[kentuckyslider]

I'm putting it back together from the turbo rebuild today. I rebuilt my starter while the intake was off and switched back to mobil1 15w50 for the summmer while the car was down. I'm also switching my rearends out from my j30 3.91 to my R32 4.36 for the track. I will take pictures of everything today and I promiss dyno results before my race season opens on April 3rd. I've already canceled on my tuner twice so I told him I wouldn't call him back until I had The car ready. Oh yeah, I installed another .4 bar spring in my WG so my base pressure will be 1.3bar(18psi) and I'm going back to Et street radials from drags so I can race in the steet import class in Nashville. I'm going to finish it up as we speak. I have to install the starter, the new intake, and the turbo and wastegate. Then drive the car to my friends house that borrowed my 4.36 R&P and switch the diffs out. I will update my thread tonight!!!!

[kentuckyslider]

Got the car running again last night but didn't get the rearend in it. I installed the new starter, turbo, manifold, and wastegate, and the ISIS intake manifold. I will be installing the 4.36 diff today and I'll make a video of the holset in the next few days and I'm hoping to be on the dyno thursday if my tuner can fit me in. Here are some pics to hold you over.....

[Kalypso]

well done, it feels good having a fresh starter I wrote on an article on rebuilding them did you use it?

that turbo is husky...

[kentuckyslider]

No, I had a local shop rebuild it for $90 with a 2 year warranty, but it seems to drag a lttle and is a little harder to turn over and I know I have good conections and altenator. It was good 9 out of 10 times before the rebuild but sometimes I would have to let it set for a minute after hard driving. I might have to take it back to the guy and have him look at it??

Anyways, I got the 4.36 diff in it and it is hitting 16psi(the WG spring) way to fast but it feels very strong. I am hoping to have it on the dyno Thursday but I haven't talked to my tuner in Nashville yet to confirm the date. He hasn't seen the car since it was dynoed 2 years ago with stock cams and intake on the GT2871R on 93 pump. I will try to get a copy of both dynos to compare my old setup to the new.

[nelson8708]

looks good, cant wait to see the dyno sheets / some video.

I dont think hitting the 450whp you want will be a problem.

[Kalypso]

Def take it back, it sounds like the brushes aren't good???

I don't know but the sluggishness strikes me as a bad connection.

after I rebuilt mine It was firing up instantly like that f*cker was mad at the world.

great build so far man... nothing else to say about it really. im happy for you.

[ZeNkI S14]

I was told about the hx35 and it caught my interest and wondering what this turbo is capable of. I am running on a 2871r .86ar and also was wanting to go top mount as well. i wanted to know what rpm full boost kicks in as well. hop town is near bowling green bout atleast an hr. but i am interested in the hx35 setup waiting to see the dyno results. hopefully i can sell my turbo setup so i can go top mount.

[mistamacadamian]

its capable of alot. look on hondatech and see how the hondas are pushing 400+. dsm's running close to 500 on these. 13psi on KAT with stock head was making 313hp on a dyno i saw. and i got a friend whose KAT with a hx35 making full boost at a litte under 3500. if you have supporting mods I.E. cams/intake mani/proper tune. stay tuned to this specific thread and my hy35 build, slider already said on 16lbs it was fast so imagine 20+ where these turbos really open up. any update on this slider? i wanna see a couple pulls inside and out the car !!

[kentuckyslider]

Well took it to the dyno thursday and had some issues. It was leaning out up top past 6500rpm and the safc is hooked up wrong and all the corrections were backwards. I'm removing the safc and running a hard line to my fuel pump and going back in the next 2 weeks. Here is what it did on the first 2 pulls at 18psi before I decided to take it off and go home and figure some things out. We played with fuel pressure and the safc and it was still leaning out. It's funny how these things always happen on the dyno for $125 an hour?? I hadn't really pushed the car hard with the holset yet so I didn't know what to expect. I will get it figured out and up to 425-450whp soon enough. I am considering the BEP .70ar non divided housing for quicker spool and sending my ECU to JWT for a reflash after i data log my next dyno run?

[Solow240sx]

Did your nismo FPR fit well with the intake manifold, and the jgy fuel rail?? If i try to put my FPR on my rail like you have yours it seams to hit my greddy intake manifold, unless i would bend/shorten the output where the fuel line connects?? Just wandering if u had the same problem??

[kentuckyslider]

I slightly bent mine witha deep well socket and a nut driver and it cleared fine. I would suggest cutting it down just before the last barb on the return nipple and then bend it even less then I did.

I got my fueling issue fixed. I hard wired my fuel pump with 10ga wire through a 30amp relay using the original power wire as my switch source and my FP is holding steady with boost. Also, my safc some how got put on flap instead of hot wire and the in and out were wrong. I got that fixed and it's holding 11.2-11.7 afr's with 20lbs of boost on 93 pump gas all the way up to the 7800rpm rev limiter. I would say I'm very close to 400whp at 20psi of boost and the turbo is barely even on the map at that level. I will be back on the dyno in the next 2 weeks shooting for 430-450whp on 110 race gas in the next few weeks. I think I will max my injectors out somwhere around 28psi and then I'll back it back down a little.

Next I will be doing a single scroll BEP .70ar turbine housing(should increase spool by at least 500rpm, rush racing 2 step anti lag, and eventually 96lb injectors and a lightning MAF tune

[gixxerbob]

what is .70 ar eqquivalent to in cm...14cm?

[kentuckyslider]

what is .70 ar eqquivalent to in cm...14cm?

I would say that is close. Tim's Turbo also said he can have a garret .63ar housing machined to fit the holset turbine wheel. I just haven't got a firm price on it yet. The BEP housing will spool quicker than my stock housing only because it's non TS. I could have gotten close to maxing out my tune with the HY35's 9cm2 housing but I wanted the option for more down the road. I've seen a well tuned 3100lb DSM with my turbo do a 132mph trap. That's 550+whp easy. That was also at 37psi. I don't know if I'm prepared to push my motor that far???

[idahotuner]

i want to make 550 to the wheels with 25-30 psi
