what series of engine do i have?

[jstow04@gmail.c]

sorry guys just gotta know. i have a 93 honda wagon ex, what series of the f22 do i have?

mine has just hit 280k, not bad but if i were to try to tweak it should i consider a new engine?

[noobcake]

the code is under the upper radiator hose kinda

but its an a6

93 Ex, you have the f22a6. The 93 Lx wagons have the f22a1.

why not just look at the engine block next to the timing plug if its not dirty enough you can see it there best to confirm.

[bcjammerx]

if it is dirty...spit on it and rub it

[Darkshowdo]

Your Most likly have the same engine as the 93 coupe model. which is a f22a6 which it pushes about 135hp stock.

heres a little breakdown on Engines so this OP is clear on what he has.

90-91 DX ( F22A1 )
90-91 LX ( F22A1 )
90-91 EX ( F22A4 )
91 SE ( F22A6 )

92-93 DX ( F22A1 )
92-93 LX ( F22A1 )
92-93 EX ( F22A6 )
93 SE ( F22A6 )

now..so you dont get confused.

90-91 ( INTERNAL COIL )
92-93 ( EXTERNAL COIL )

both the F22A1 and F22A6 has cast manifolds although..the F22A1 stock has a 4-1 exhaust design. The F22A4 has the better ( tubular ) exhaust manifold." better flow" between the 3 version.

F22A1 ( 4-1 exhaust setup )
F22A4 ( 4-2-1 exhaust setup )
F22A6 ( 4-2-1 exhaust setup )

^ now..even though...the A4 and A6 has both 4-2-1 setups..the A6 has a more restrictive exhaust manifold.

if you take a A4 exhaust manifold and Downpipe and put it on a A6..and put a H23 upper intake plenum onto the lower half othe A6 intake manifold.

you will get around 140-150HP just from doing that (*** includes CAI ..highflow cat ..and Catback exhaust. )

( I/H/E )

thats a nice power adder from using OEM honda parts

more detail:

F22A1 ( economy ) PT3
F22A4 ( different exhaust setup...but same as the A1 ) PT3
F22A6 ( wilder camshaft..different intake manifold ...dual intake runners " IAB" ) PT6..controls the IABs " intake butterflies "

NOTE: ^^ if you have a LX or DX..you can use the 1992-1996 Prelude S P12 ECU for a 10HP gain.


*** REPEAT: take the A4 header and DP and put it on the A6 to gain a little bit more HP out of the A6..around 5hp.

A1 ( 125hp )
A4 ( 130hp )
A6 ( 135-140hp )

NOTE: braking systems... ALL 90-91s came with rear drums. 92-93 DX and LXs came with Drums..92-93 EX and 93 SEs came with rear discs.

all 92-93s came with Driver side Airbags. 92-93 EXs and SEs..came with Anti-lock brakes.

so..92-93 EX and SEs..are top of the line of the entire CB line.

I dunno if I'm forgetting any more detail..but its so the OP knows whats under his hood.

OR..on the upper timing cover. under the powersteering hard line. ( a white sticker ) ..you can't miss it.
