Holset HC1 and Manifold

[Nissan2367]

I searched and could find nothing on the Holset HC1 but if any of you find anything just steer me in the right direction!I just bought a Holset HC1 from a friend. from what i understand its a smaller of the Holset turbos off of a 95-00 dodge cummins. It has a 2/5" intake and 2.5 vbad outlet. I think it will be perfect for my goals of 400hp... till i want more Now my question is i have been looking everywhere and i cant find any good top mount manifolds for it! I dont want so cheap ebay crap that will crack but i am on a huge budget so i need something that will fit in that!It has a t3 twin scroll inlet but i was just thinking i will switch out the exhaust housing for a non twin scroll and buy a plain t3 manifold.let me know any thoughts! Thanks!

The stock manifold is perfectly adequate for your power levels. You won't find a worthwhile top mount that is budget friendly I am afraid. The question is, will it fit... do you have the turbo yet?

The stocker is also divided T3.

Good point! Maybe ill just do what you did and shim it out with the flanges... and no the turbo will be here by the end of the week! Ill have to order an external wastegate and have it welded to my manifold... not sure where to go for that! I am kinda broke right now but i got a great deal on that turbo!

The guy that welded mine was on the east side. I can tell you how to do it. It is more time than anything else.

Once you get that turbo, I can figure out if it will fit or not for you. Your going to need divided spacers BTW.. mine is open so I just used flanges.

when i had a hx35w on my 20 i retained the stock cast manifold and used a ebay 1/4 t3 spacer and used extended exhaust studs to compensate for the spacer, worked very well!

Awesome i am pumped! I am putting the clutch in on friday along with new rear axles and sub frame bushings...then ill save to buy pipe and a wastegate to get that thing on!Evan you find out if you can be "sick" from work on friday and help me out?

Keith, Ill call you sometime today.

Sounds good... has anyone on here ran the HC1? I am just wondering how they liked it

[Cjmartz2k]

The reason you haven't found anything is because it's an H1C, not an HC1. Try that. There are a couple different H1c's, but it's similar to the HX35 in power and spool.

oops... Typo! I searched all over google to research up on them and it seems perfect for my 400hp goal. there are KA guys getting 400+ with it so i figure that will not be a problem at all!
