the $5 SPFI hose


Recommended Posts

I paid $5 at Turner PAP for the top hose from an SPFI EA82 (bolts onto throttle body) and used a 2 3/8 to 2 5/8 adapter, took off the small subaru gasket that normally goes between carb and air filter assebly.

 

Went right on, tightened her down with the hose clamp that was already on hose, and presto.

 

At the end, I didn't get an air box, but I just put a 4" chrome deep dish air filter assembly on there. Now I have my PCV system hooked back up on it, and it looks kinda cool with this "Subaru FI" thing on top of my hitachi. Now I don't get the whispy sound of the carb sucking in air, and I don't have that small leak I didn't notice before. coolio.

 

Maybe some day I can grab pictures.

 

PS: Engine sounds better, I actually have power above 5k now, and I think that's due to the small leak I had before.

Would you believe that that is a $320 hose?

 

I know, because it's common for them to crack, both at the outline of the cast-in "SPFI" rectangular logo border, and around the PCV and IAC "nipples". I had both cracks. I carefully black-RTV'd mine a couple of weeks ago.

PAP are generally just good.

 

The 4 barrel from an RX7 is supposed to be a hitachi basically jetted the same but only four barrels (it's something like two of ours put together) and i looked for it, but the car that came with it had it taken out.

 

I guess I'm still going for the weber .32/36
