I currently am building a B18a and plan on running the Holset for ***** and laughs. The question I had, after searhing was, where are you guys getting manifolds for this, and what kinda flanges are you using? Im assuming something needs to be custom made, but what all is required.

Yes I searched, but 110 pages is difficult to find stuff. thank you

 

***** and laughs? many holsets are perfect depending on which you run. all the ones that you can spool on a honda ive seen are the common t3 or t4 flange.

 

Searching requires more than a minute of light browsing. Any internet site that displays a holset for sale makes it clear its almost always a T3 flange. As for the outlet, it depends on what turbo you have. In many cases, it will be cheaper and easier to get a v-band, since many use that for the outlet.

The HX and HY35's are almost perfect for Hondas. Better yet, some are divided housings, which can help spool it much faster if you use a custom manifold. Otherwise almost any manifold will work.

Go back to the Holset page and start reading. That info is there for a reason.

 

im doin it mainly because theres alot of people who say it wont work, wont spool, etc etc. And apparently showing them proof isnt good enough, so Ill do it on my car because it seems pretty unique.

And thank you ^ above for the info on the flange. I dont know why but I honestly did look and didnt seem to find where it said exactly what flange would work, or any real clear cut information.

 

how much power you looking for and that could help us tell you which holset and which turbine housing would work best to reach that goal

just for instance the hy35 comes with a 9cm housing and on a 18t 20v vw spools and makes power almost identical to a .63 t3t4 50 trim and makes for a flat tq curve from 4600 rpms to 7000 rpms before the tq falls off slightly while making about 335whp

this was just an example if you give us the aanswer to my first questions we can help you out and user theshodan could be very helpful i think he is the best on this site on turbo knowledge

 

ideally id like to make 350+. im aiming for the + though. Basically the top HP that a built bottom end, non sleeved, B18A can run. Also will be upgrading the springs and retainers.

 

hx35 12cm housing...and copious amounts of boost will do the trick...and if thats not enough you can always upgrade the compressor to the hx40 wheel

 

you adding a cam as well

wouldn't it be cheaper to just buy a vtec head than build a ls head

 

what the guy above me sounds good on what turbo to get and if you could get a divided turbine and a properly made divided manifold and you'll pick up 5-700 rpms of spool

 

I ould go vtec, but Im not really interested in doing that right now. I just want to get the engine built then put it into a car then I can work on improving it even more. AS for cams, Im not sure right now. would ITR cams be a good idea or no?

 

in a vtec head they would be a great idea but you would need to upgrade the springs and retainers when you did the cam swap

 

im already doing springs and retainers. stock valves for now. built bottom end non-sleeved.

 

trust me when i say this...the hx35 @ 15+psi will be plenty for the streets. I ran a ls/vtec w/ that setup and even though p72 heads flow better...even w/ vtec disabled it still roasted the tires off...bfg 225's...nothing special but it was plenty of speed for me and id always find myself laughin at vette's :-)

also on a sidenote...these turbos hate backpressure...so do everything you can to get at least a 3" exh all the way out...i ran a stock exh w/ a cutout and between being closed and open...about 1000-1200rpm spool different from stock exh>open dp and it all made a ton more power...just had to compensate on the fuel trims for when the exh was open it run a lil leaner....so i added some fuel so id just be rich when the cutout was closed...which was hardly ever

 

So 15 psi would be more then enough? I was thinking 20 would be the upper most limit i would run. And that was my only concern was how I could manage to ever get traction.

And I was planning on running 3" the whole way back. Glad someone posted that that would be the best idea exhaust wise.

Im told the Hx35 is a hella loud and good sounding turbo? Is that true?

 

and that matters because why ?

 

just curious is all. If im gonna get it I wouldnt mind knowing what its gonna perform/sound.feel like.
