Actually the v-band is better than the bolt up one. When someone refers to v-band or bolt up they are talking about the conection of the hot side of the turbo(where the exhaust flows) to the downpipe.

I tried to cross it in my Holset database but couldn't come up with anything but will call them in the morning to find out what it is and what it comes off of!

Also i do know most of all the HX35W came off of the 94-98 dodge cummins 12 valve motors!
Now they had 2 different ones the automatic had a 9cm housing and the manual had a 12cm housing!

just my $.02

You need a fuel system upgrade, a DSMLink or SAFC, FMIC, cams and other internals will help, etc... after looking at your profile, I suggest you stay with the stock turbo or what you have now and do other upgrades than go to the HX35.

Just got phone with Holset and they said check your number as that is not a good Part number for a Turbo!

No the 9cm^2 housing off the automatic is an HY35 not an hx35. It has a smaller turbine housing AND a smaller turbine wheel than the HX35. Holset phone reps have proven not to be a good source for information. Diesel shops are. But they will laugh at you if you mention putting this turbo on a 4 cylinder car. They do't understand gas motors that well though. . . any more than most gas motor enthusiasts understand diesel motors, I suppose.

Bolton vs. vband???? A holset is only bolton with the Bullseye Power Bolton housing. They don't come with this when you get the turbo off the diesel pickup. The hx35 has a divided inlet (twin scroll) turbine housing. Do you want a bolton-ish turbo? Then go to theturbotrader.com and contact Nick. He can get you the housing. Or contackt Bullseye Performace directly. They may have a few left. All hx35s have a V-band turbine OUTLET when you pul them off the truck.

There are 2 different compressor wheels that may come with the hx35. The early hx35s have an 8blade 56mm inducer wheel, and the later ones have a 7blade 56mm inducer. The flow and efficiency between the two is apparently so similar that holset never released a second compressor map for the the 7blade one. So don't worry about which hx35 you have. All the hx35 turbos will perform about the same.

The hx35 is a 500whp capable turbo in the bolton BEP housing, with the spool of an evo3 16g in that housing. It likes high boost and flows 52lb/min. 3-4 lb/min more than a 20g or a 50-trim. You definatly need all the fuel mods, fuel control, and intercooling mentioned. You'll need at least 650cc injectors JUST TO GET INTO THE POTENTIAL of this turbo. I recommend larger than 750cc and dsmlink or other eprom hack. You will need a walbro 255 fuel pump w/ an adjustable fuel pressure regulator. You will need a large ebay intercooler. You have barely enough clutch for it. But you do have enough transmission for it. You need a down pipe. The stocker is a real choke for a turbo that flows this much.

If you want the power of a 16g, and upgrade to a hacked eprom later when you're ready for more power, then this turbo is fine because mine spools as fast as my small 16g. The BEP housing and other parts to bolt this turbo on, a front mount, set of 650s and safc, and a fuel pump with an adjustable fuel pressure regulator; and you're set for 350whp on pumpgas with 16g spool. With PLENTY of turbo for a later goal of 100 more horsepower. You may need to do the tank siphon (syphon) mod. Look this up.

You have 1995 car. In all likelyhood you have an EPROM ecu. Which makes your life a whole lot easier when tuning for a turbo this big or bigger.
