VR17 Posted April 17, 2003 Share Posted April 17, 2003 ive done a research on 2nd gen USDM model 88-91 Honda CRX Si,Dx,Hf...(since i own one.. heh) 88-89 CRX's don't have side impact beams in the doors, the 90-91 do. All CRX's have rear drum brakes except the 90-91 Si's 90-91 have a round instrument gauge cover while the 88-89 one is more squarish 88-89 door moldings are taller and flatter, the 90-91 ones are shorter but stick out further and have a beveled edge to them. 90-91 rear lights have a 1/2 inch black edge all the way around them, the 88-89 do not. 90-91 have have fake air ducts molded into the bumper 88-89 have slightly different front and rear bumpers than the 90-91 90-91 bumper mounted turn signals are clear with amber inserts in them, the 88-89 lenses are just solid amber and shorter in length. 88-89 Corner mounted parking lights have their mounting screws visible while the 90-91 ones are attached by hiden screws. 91 and perhaps 90 headlights have a vent in them to help prevent moisture buildup. 90-91's are the heaviest, the 89 is lighter, and the 88 is the lightest. In each year the hf is the lighter model, then the DX and finally the Si weighs in at the most. 88 manual transmissions have an input shaft with 21 slpines 88 has a 21 spline input shaft, the 89-91's have a 20 spline shaft 90-91 clutch is 212mm, the 89 is 200mm and the 88 has either a 200 or 190mm, I can't remember which. 88 does not have a clutch safety switch. Which means it will start without having to press the clutch in. 88-89 Si models have 105hp, the 90-91's have 108hp due to different ecu settings and possibly a slightly different cam. 88's have pillar mounted seatbelts,90-91 have door mounted belts, 89 si's and dx's have door mounted belts, 89 hf's have pillar mounted belts. I could be wrong on some of this belt stuff, if you can confirm or deny any of it please let me know. Models with door mounted belts have a wider pillar at the end of the door to accomodate the belt mount, this also means that the glass is and inch or so shorter. 90-91's have a red seatbelt warning light built into the dome light. 88's have what Honda called "passive rear steering" which makes them slightly more agile but some owners complained that they didn't like the "twitchiness" feeling of it so it only existed the one year. Rear lower control arms changed between the 88 and 91 years and the rear shocks have different mounting points but I'm not sure what year the change took place. 88 has slightly different sized front shocks. 88 ecu has a different internal design than the 89-91 but the inputs and outputs are the same and ecu's can be swapped between years. I know this one since most chip makers don't offer a chip for the 88 and my car was a gunea pig for Dinan to test a later year ECU on. 88-89's have the hazard light switch on the top of the steering column, 90-91's have it mounted on the dash. 88-89 Si seats have a white pinstrip, 90-91 Si seats have a red pinstrip. 88 has a pocket at the bottom of the drivers door 90-91 Si's and perhaps the 89 Si have a mesh pocket on the back of the seats. 88 cam indexing is the same for all the engines, 89-91 si's have indexing that is different from the other engines. 90-91 and possibly the 89 have larger reverse lights that are set further to the sides than the 88 Link to comment Share on other sites More sharing options...
