I would say that is well worth it... That's twice the horspower.... I mean, it's not a big deal since the Hf is so slow already, but it's alot more HP and I'll think you'll be happy.... and I would guess that an Si engine into the Hf is a rough equivelant of an SOHC VTEC into an Si... do it... it'll be cheap too....
Yep, no wiring mods. If you can find a good Si engine, do it. One thing to note though is the HF has weaker drive axles and different spindles than the DX or Si. Honda did this for weight savings. The cool thing is that you have the lighest of all 2nd generation production CRX's. I believe the car tipped the scales at just under 1900lbs. By the way, you will have to change the tranny is you want to use any of the performance of the Si engine. The HF is geared for fuel economy, more so than the DX tranny. Have fun!!
that means i will have to cut my door caps off my current doors assuming I can find 88 doos in near perfect shape.
I think I will just have to stick to my doors with the seatbelts taken out.
I was needing new doors for my 89 CRX, so looked into swapping out the doors of the 88 because they were lighter and I could save almost 50lbs. If I am not mistaken, they won't swap over. The 88's are different at the window frame close to the rear quarter glass. The 89's have those two large pins that catch the door there. I looked at one in a junkyard to see the difference and to take measurements. If anyone has done, this swap, I would like to know how they did. From what I could tell, it could not be done easily.
