Turboing a Stock Hf
 

Has Anyone ever Turbocharged a D15B6 (HF engine)? Probably pretty simple. What size turbo would you need to use?

Nobody wastes their times, they dont even like a little nitrous!! I found that out! hahah :P

Re:Turboing a Stock Hf
 

You can turbo anything. I would say something along the lines of a T25 or a tdo4. Some thing small that would spool quick since you dont need that much PSI.

Re:Turboing a Stock Hf
 

Those 190cc injectors on the HF's deliver mad fuel :-\

I wouldnt waste my time, your talking about turboing a 62hp car, and probably gain about 50-60hp. Which would be about the same output of a stock d16a6.

Take the HF head off, put a a6 head on, then turbo it.

Re:Turboing a Stock Hf
 

he'd have to change the pistons too, it'd be easier to just swap in a a6 or a b2 or something.

Re:Turboing a Stock Hf
 

at least, i would get the a6 head. then turbo it. you can find a head for like 100 bucks if you look in the right places.

Re:Turboing a Stock Hf
 

Or even cheaper find a dx head and a a6 cam.

Re:Turboing a Stock Hf
 

I'd say either mini-me, or swap on an a6 head then turbo..

Re:Turboing a Stock Hf
 

You cant swap on an a6 (or any other 16V head) without changing the pistons. They are cut for only 8 valves and will destroy the other 8 if you try to use a 16v head.

What he said!!

Re:Turboing a Stock Hf
 

vitara pistons for $100 will clear that up. ;)

w3rd

Re:Turboing a Stock Hf
 

better yet, just get another D16A6 engine, or a JDM D15Vtec and start there. both would cost probably about the same. or even a SOHC ZC or DOHC ZC

maybe you dont have the money for this. is this why you are askin? its ok, you can admit it. some of us are broke to. :slouchin in my chair:



yeah, if you wanna boost your HF motor. its cool. you will have more than some of us....
:falling out of my chair now:

Re:Turboing a Stock Hf
 

buddy of mine put a JRSC on his and a zex 55shot. Even with 235K miles, the car never made enough power to break.

Look at the HF intake/head/TB vs the A6 stuff and you'll see why one is 58-62hp and the other is 108hp..

I was told even HF injectors are 240cc... Could be wrong, but I can't imagine honda buying a totally different set of injectors just for a POS HF...

Re:Turboing a Stock Hf
 

For the longest time I've always said never put a 16valve head on a HF but I've read about 4-5 guys who have put a6 heads on D15b6's without problems. You'd think the valves would hit. A few write ups were on www.hondaswap.com


The d15b8 which is basically a newer style HF engine in the EG's is only a 8valve as well, but has cut outs on all pistons for a 16 valve head.

I'd definatly try it.

Re:Turboing a Stock Hf
 

are the rods smaller in an HF compared to an A6?

Re:Turboing a Stock Hf
 

They look identicle to D15b2/b7 DX rods

Re:Turboing a Stock Hf
 

I'm running this now! When the Z6 block blew I only had the CX motor usable. Swapped head/manifold and works great.
Pulls harder than when I had the D16Z6 in! Especially on the lower end.(Higher compression)B8 has flat top pistons and Z6 has dished. Even boosted it just fine.
Note:
Removed oil jet on block.
Had to use the CX timing belt.
Had to use CX pcv valve/tube/grommet.

Re:Turboing a Stock Hf
 

I have a d15b2 motor that I'm putting a z6 head onto....

nothing like a d15z6 :)

I'll swap the pistons for the virtata pistons becuase this motor has 205k miles on it and im sure the rings are ------ shot.

then i'll prolly post the little bitch block and we will see how far 15psi goes :)

should lots of fun for a little civic dx. a hell of a lot better than stock atleast.

Re:Turboing a Stock Hf
 

The rods are the weakpoint in the D15, putting the vitara pistons in isnt going to give much insurance.

Re:Turboing a Stock Hf
 

I was just wondering because I have 6 just sittin in the bag of my garage. They all ran... does anyone want? Free for taking.
