Can't believe some of you think the HX/HY-35 is too small for your Honda's.


You'll find more information here on Holset's than anywhere on the net:

Including some compressor maps for the different years. Many of you are right, these turbos respond better to higher boost levels. At the low boost levels, it is possible to surge.

 

you gotta think a 4G63 is a 2.0/2.4 liter and most of the people on the dsmtuners.com are running 15-20psi on the holset. Not many people can run this on a 1.8 GSR or B16 unless your built if you are more power to you

 

you know why they are too small... our motors flow better. and the reason one is too small for me is i have a 2.1 liter fully built (block, head) ls/vtec. 500whp on pump is the goal. i can make that at 18psi on my current turbo. it would take a holset 30 plus. the holset is a good turbo for a drag car and i will be using one on my drag coupe

After researching i can agree with this. They need too much boost to perform great.

 

the current project is really not ment to break records...this time my goal is to create a street beast that can shred the tired loose on damn near any gear...i want a radical "WTF was that" honda, LOL!!!!!


somebody get my spare hx!!!!!!!!!!!

 

if you think about it you could do that with almost any turbo. The Holset just has the best price to get it done quicker. They aren't bad turbos but they need alot a psi to get full potential.

i know you can do it with MANY other applications...my boosted coupe can do it...for the price it is great and from what we have seen so far most people that are using them are not boosting a lot but they are very happy with them...

 

your right. I can't lie if I could see a good dyno on a 1.8LGSR/LS/Vtec I think that would change my mind greatly.

it's not about being right, i just want you to become part of the cult...that way when you build a stronger motor you will NOT have to replace the turbo

 

Ill tell you from my experience...ive ridden in t3/t4ob cars and bb tubro'd cars...running numerous 15+lbs of boost...and its not the same...

people speak of surging the compressor...the compressor cover itself has surge protecting built into it already...most companies are now catchin onto this and are drillin their housings...so a smaller motor can run a huge turbo...

yes the holsets love high boost...but even at a mere 10lbs its not 100% efficent but it gets the job done...and it flows a crap load so hi-boost isnt really an option on an un-built motor...

and for people who say these are drag only turbos...heh i run mine on the street and 4k full boost of 10psi is hella fun...run more to be more efficent heh yea right...i already tear them loose till the top end of 3rd....any more...and well it just be pointless...i personally think they are a great street turbo....enough lag to get you rollin...then the onset of power...i wish the transition was a lil smoother...

and my main focus on runnig the holset...many honda peeps have never even ran them...it cost me $215...about 450 cheaper than a equal performaining afetrmakret turbo....and its friggin huge...to scare lil people away...

 

and im workin on some dyno time...but as of tuesday im back in skewl...so unless a place runs a 50 dyno day...i dont think ill make it...unless I start a collection and everyone chips in a few bucks...then id make it worth my while to go...

Right. Please send me a link showing some flow data.

With a 2.1 at 18psi? Got a dyno graph showing that?

The holset flows more than enough for your 2.1. If anything, it's too big. If you ever could hit 30psi with it, you'd be making alot more than 500hp.

 

i dont want high boost horsepower... its just nothign but hot air. and me and a garrett engineer desgined this turbo. everything from wheels to housings are custom. i am having a holset hybrid made by the same engineer for my drag car

DSM: 210HP @~11? Psi
B16, B18C, B18C5: 160-210HP... N.A.

There's your flow data.

 

does the holset hx35/h1c/hy35 snail use standard t3/t4 oil feed and drain or a standard t4 oil feed and drain? also, is the turbine inlet on a h1c a t4 or t3? im asking because http://cgi.ebay.com/ebaymotors...ZWDVW &lt;-- that threw me off.

I don't see a B18C5 making 210.

Make an apples to apples comparison. Non-Vtec 2.0L DOHC to Mits 2.0L DOHC.
Honda-126-143HP. Mits-135. Again, I simply asked for a link to cylinder head flow for hondas.

 

the funny thing i find w/ holsets is that the love the higher pressur eratios...so in fact having a engine that flows less...will in turn make you up the boost to achieve the power levels you desire...hence gettin you into the more efficent power range...

they use a standard t3 oil drain...i just got one off a dsm cut the metal tube and ran a rubber line over it to a nipple on my oil pan....call stan from fast-turbo.com and im sure he'd bve able to tell you what oil lline pressure fittings you need

 

and what about the turbine inlet? standard t3 or standard t4? (for a holset h1c).

 

h1c is t4 i believe, but its a divided housing... i think

 

are the h1c turbine housings and the hx35 housings interchangable? im beginning to think i should run a hy35 or hx35 instead. (have je pistons, eagle rods, acl bearings, aebs headstuds, and type r oil and water pump - looking to boost 12-15psi daily, 18+ with race gas occasionaly).

 

the hx35 or 10psi will be more than enough at least imho....the h1c is the pre-decessor to the hx35...id sy the housing are interchangable...but dont quote me on that....personally the only reason id run a hy35...is on a autocross car...or a 1.6...anything bigger such as a 1.8 spooling to fast will just get more traction problems...the reaosn being...the hy comes w/ a 9cm turbine housing...and the hx35 comes w/ a 12cm housing...its setup to run as a split scroll but eq pressure will work just fine....the hx35 housing is about a .55 a/r...but if you grind out the split you can make it a tad bit bigger closer to a .63 a/r...lose about 500 in rpm spool but up top it will just make more power...

and kasso if youd ever taken a ride in my teg...youd never wanna see an rsx...theyre slow pigs...unless moded...
