Holset Turbos, PART 6

[interex]

Search G Pop Shop. They rebuild all sorts of turbos. They also will sell you parts.

Okay, I emailed them. What exhaust manifold do you think I should use with this turbo? Any info about an exhaust housing that will work well with this turbo, but still be usable on a dsm (non-stock) manifold?

There really isn't a lot of answers to my question about the H2E.

A little while back, someone had a velocity stack on a HX40 listed in the classified section. I PM'd him about it but he never answered me back. It fit perfectly on the turbo and I have not been able to find one like it anywhere online. I wish I had saved the picture... Does anyone know of ones that fit the HX40?

Check out:

Very cool place, I just bought one of their podrams

Vibrant also has them:
Vibrant Performance ::.

Or you could even try something like this:
Bellmouth Starter Collar Air Handling Systems

Lastly, you can search Ebay, there are a ton of vendors on there selling Blox bellmouths.

Also, for some really good reading on why you should use a bellmouth, check this out.

I'm on the hunt for a Holset as we speak, i'm just wondering what would yield me the fastest spool up on a stock short block and built head?

HX40 or 35? Which exhaust housing should I go with? Divided or undivided exhaust mani?

I also plan to run the stock IM with a larger TB (possibly N/T). Good idea?

I'm building the car for road racing.

Help?

As it stands with proven setups, the bolton 8blade hx35 is your best bet.

But I really, REALLY suspect that a stock 13cm^2 hx35 turbine housiing (with an hx35 of course) using a true divided runner manifold spools the fastest. I thought that there was one member who used this setup, but I can't seam to place the name or the post.

A completely shut (smallest a/r setting) VGT HE351 would lilely spool about as fast. And you can get away with an open housing. Seak out member Aero Salle. He's run this setup and had some great results with spool and follow through.

HX35, BEP .55 A/R turbine housing

Apex you are the one I'm talking about. 95 we just results I should have my stuf labor day weekend then I can post up solid airflow numbers sadly that kid on talk that wanted a 264 cam must of changed his mind.

nice!

 

[lazyazzdaddy]

Forget my Post i'm gonna be running a MAPerfomance O2 with Tial 38mm MVS.

How many people are running the HX35 in bolton housing? I know one 2g in cali. but thats it.

I've been running mine for two years now. I also have several friends that use them too.

 

[dsm-onster]

Ran mine for a year and sold the whole thing (hx35 and turbine housing) back when they stopped production for $500 to a lucky SOB for cash toward my twinscroll setup. By FAR the baddest street turbo I've ever used or had my hands on. I've run an e3 16g, fp tdo5h 18g, small 16g, 14b, t31 bep housing 60-1 (Basically an fp red with a better turbine wheel/housing). Spools like the small 16g and flows the same airflow at the same psi as the 60-1.

I also have 3 friends of mine with the same housing.

Ok I want opinions on this setup: stock 6bolt short block with balance shafts removed, p&p head with 272s, 1mm over valves, built valve train, hawver im, bbk tb, jhracing divided t3 mani, 8 blade hx40 with a bep .70 t3 exhaust housing, 3inch o2 elim downpipe into a 3 inch exhaust, 44mm wastegate on manifold, water to air intercooler, meth injection, 1650cc injectors, 2 intank walbros and tuning with dsmlink v3 or dsmap

 

[1gDSM4g63]

With the power you're look for the stock block won't hold up. Plus with the ported head and the 1mm over valves you got to have a SMIM and the DIVIDED manifold won't do any good if you're using a BEP non-divided housing.

 

[604CruisinCroat]

oops i forgot to put that i will be running a divided housing and a hawver im. Maybe id be better off with an hx35? Ill be roadracing mostly. I might build a 2.3 thats why i was leaning towards the hx40.

[turbotalon1g]

If u are road racing and doing a t3 then I would stay hx35

 

[dsm-onster]

^^^I agree with both of the above. I really think that if spool is what you REALLY want (your puttign alot of money in a divided manifold for the sake of spool) and you still want a 500whp capable turbo if you push it hard, then the hx35 with stock 12cm^2 housing (each volute is only as big as a 6cm^2 14b hosuing) and a t3 divided runner setup would be ideal.

Whats a good fuel setup for a hx35 with the .55 bolt on housing? I am selling my old 450cc and 750cc and will be getting something bigger. Should i go for e85, or stick with 93 pump?

How far will a 255 rewired with a fuel line kit from stm get me with the hx35 on e85? What injectors will be enough, 1200cc? Or more?

From the fuel flow post, it seems 1200cc and a 255 should be enough to get to the ~51lb/min airflow that the .55 housing can do. Thoughts?

I'm planning to run my 255 pump with 850cc injectors. Even when flowing 40 lbs/min duty cycle should be in the 70s.

For E85 you'll want 1200cc or more.

 

[turbotalon1g]

I have 950s and I am planning on going to 1250s

Thanks!

yea some time i will upgrade to some larger cams then my current 264/272

I'm finally installing my HX35 in .55ar housing on an FP Race manifold, and ran into some problems. The compressor cover hits the turbo coolant bung on the waterpipe. I went to the junkyard and found about 4 n/t 4g63's but none of the waterpipes had the barb for the oil cooler. Is there a n/t waterpipe that does have the barb? If so which model/year?

 

[b00stedtalon2]

That's because it is new!


I honestly don't remember exact details anymore- I've had it about a year. I think I paid around $530-$550 shipped, I know for a fact the BEP turbine housing was $235 shipped from G-Pop (beat SBR's best price by $15), and the manifold on the group buy was $522 shipped with the 38mm wastegate flange. Found a very lightly-used Tial 38mm gate for $100 as well.

I have less in my entire setup than most vendors want for a new GT35R.

My entire holset HX52 setup with JHracing manifold and twin 44mm gates came out to be 1500. Thats easily a 9 second setup right there!

There are no waterpipes with a oil cooler line, and without the turbo line. There are pipes with the turbo feed and no oil line. You can run a 90 ofh for the oil cooler and a n/t pipe to fit the turbo.

I have the same setup but I opted to convert my 44mm hooks to 38's because I don't plan on running low boost really ever and 38's are a hell of a lot cheaper than 44's

I have one with no turbo coolant fitting that has the cooler barb. I think mine was from a 91 nt, IIRC

Anyone with a hx52 with billet wheel ever mic their internals? I don't know if I overlooked this before but there is a hx52 PRO which if we have the billet wheels I would think would be us. They are 71mm inducers compared the 66mm regular hx52. I am going to mic mine as soon as I get home to see if I have the golden ticket

 

[dsm-onster]

Who told you the hx52 "pro" was 71mm? Just curious.

Yes Jeremiahs hx52 is not billet and it measures 66mm at the inducer. Click. Holset is in the habit of just makeing their wheels billet with no other change. There's 7blade hx35 billet wheels that are oem shape and fin design. Along with 6 and 7blade hx40s. Although all 6blade 56mm inducer hx40 wheels (The small ones) are all billet it seams.
