Hey

I have a 90 civic hatch when i brought it (couple years ago), i was told it was a 'Si' model.
But now after researching i'm not sure what model it really is.
It has

1.6 liter engine (block says D16A6)
4 speed transmission
Dual Point fuel Injection.
It has a Si badge at the back (but anyone could of put that on)

Could anyone tell me what model it really is?

thanks

jlicrx · 08-07-2007, 04:18 PM

sounds like it may be STD model - what is the VIN number?

D16A6 is the Si block, but Si models were MPFI and all had 5 speed transmission and factory sunroof

does it have a rear wiper?
does it have a console or just a boot?
does it have a factory tach?
does it have a red plastic panel between the tail lights or a plain black piece?

eg6sir · 08-07-2007, 04:22 PM

if its an SI it'll have rear disc brakes

ddjmagic · 08-07-2007, 04:26 PM

No rear wiper, No Tach, Plain Black piece between the tail lights, not certain but i think it has drums at the back.

90-91 Civic Si did not have disc brakes on the rear - only the 90-91 CRX Si had discs

should have VIN number 2HGED634#L####### - the ED634 is the 3 door STD hatch - the L is for 90 model year

'91rex · 08-08-2007, 01:22 PM

prolly a previously totaled car with a b/s motor to get it sold....who know's....

HB90SI · 08-17-2007, 10:02 AM

The 88 thru 91 SI's came with a five speed trans, I have an all original 90SI.

dont forget the sun roof

civicious · 08-17-2007, 01:35 PM

a dead giveaway is the sunroof. If it doesn't have a sunroof, it isn't an Si.

Sounds like someone threw an Si block into a STD hatch.

If you don't like the 4 speed tranny, I'll trade you a 91 DX 5spd for it straight up

Because of the lack of the accessories you mention, the black piece between the taillights, drum brakes, DPFI, and four speed transmission, it sounds like you have a STD model. Someone apparently swapped in an SI longblock, slapped on an SI badge, and kept the four speed transmission and DPFI.

90-91 STD vinyl interior + 94+up Integra center console for interior perfectness.

SIs are overrated, in my opinion. Honda added TONS of extra stuff you don't need, which added LOTS of weight. But they gave it a drivetrain with just enough power and shorter gearing to make it slightly faster than a DX. DX with swap > SI (with or without swap) ANY DAY!

i know this is kinda sorta on topic here....

out of what years

USDM CRX DX-R · 11-30-2007, 09:50 PM

The STD is ALWAYS the lightest Civic of a GIVEN year. Although, because later models had door mounted seatbelts, a 1991 STD is going to be heavier than a 1988 DX.

K2e2vin · 12-01-2007, 06:25 AM

HF=CRX. STD's are going to be the lightest for the Civics; but the 88-89 DXs are probably just as heavy as the 90-91 STDs if not lighter.

cleanef8 · 12-27-2007, 11:07 AM

how do i know if my crx is an HF or a DX?
