I was just speaking with a friend and discussing how we are (myself included) say if you are going to swap a CRX to get the HF cause it is the lightest.

Here is what I am thinking though, once the car gets prep'd to accept a swap, and I'm not talking about "swap" mounts or anything like that, but just the OEM Honda parts.

Once we get a HF prep'd to accept a swap we have added DX/Si spindles (to accept axles) and items like that and aren't we back up to the weight of the CRX (DX)?

Now I understand that the HF bumper support is lighter but before we even get the swap in we are bring the HF back of to weight. You can also get the aluminum drums to reduce weight also.

So does it really matter as far weight is concerned from the HF to the CRX (DX) is there really a difference when we get done adding the additional oem items such as spindle for the swap?

Just some food for thought for everyone out there.

 

i got a 91 SI and its light enough for me

 

you dont want the hf spindles you want hf/si spindles

I thought they are sound deadining free also?
It's a very good point you bring up.

I think alot of the weight isn't that much but like the missing stuff like a colsoul wrapping to the shifter compared to the floor

 

Hf's also have the shorter turn rack, but lack a rear swaybar (which you will probably upgrade anyway). They smaller front diameter sway which is more desirable though, atleast imo. I'm sure after you swap the spindles, the HF is still quite a bit lighter than the dx or si, but I could be wrong.

 

sorry you dont want the dx spindles you want hf/si spindles.. sorry its been beer thirty for a while now

WHA I think you mean this


"sorry you dont want the HF spindles you want DX/Si spindles.. sorry its been beer thirty for a while now"

DX also doesn't have rear sway bar. You are correct on the HF sway bar it is lighter.

fixed that for you..go have another
And lay off the lacquer thinner..

 

HF is pimp because it has a 5k redline on the dash, so when you bring it up to 9k and bury the needle all your friends are like "whoah"....does the dx do that???

 

**** so I need dx si spindles.. ****!

haha!

 

but that dosent sound right.. today my buddy who bought my old 89 dx hatch. had to replace the front spindles on it because the si axles wouldt work in it.. he is also planing on doing a bseries swap.

 

my STD hatch had 0 sway bars and still does

 

maybe its a std... gay *** dpmfi i know that

 

Rewiring a DX for MPFI is supposed to be hard compared to upgrading spindles on an already-MPFI HF.

But the pickings of good HFs are getting slim now.

 

so would the spindles outta the std work? I dont know how to tell if its a std or dx

 

You need DX/Si/EX spindles that will accept axles from each of those models.

As we all know now the rewiring part is just about as easy as doing the spindles. I agree with you Fireant

Back on topic.

 

My brother and I wieghed our cars on the same scale and they weighed the same. He has an HF with a B16. Thats about it. I have a Si with the A6 and have a lightweight battery and lighter wheels. Those are about the only "major" differences. So I guess it could be said that the HF with a B16 is 100Lbs lighter than a Si with a B16b/c the the B16 is about 100 Lbs. more than the stock motor. Sry. if that doesn't make sense.

 

The HF has a smaller gas tank and
how much gas was there in each car?
how much washer fluid?
Factors to be considered..

1 gallon of water equals 8.33 lbs.
1 gallon of gasoline equals 5.8 to 6.5 lbs.

i think it depends on your level of prep and just how serious you are about weight.
some things are different, but wont matter because they'll be the same later- axles, knuckles.

some things are heavier, but may be better and are easilly swappable- sway bars, brakes

some things are heavier, but swappable or removable so you just have to do it- ac, bumper supports, sunroof assembly, doors/seatbelts .

when it really comes down to it, the shells are pretty much the same, although i've heard a lot of people question wether or not later cars or si's got more or thicker bracing. i don't have any proof other than the fact that most part numbers of the tub are in fact different part numbers, but after stripping a few cars to the shell, any differences i can see are all beneficial in the later cars. i'd even choose the extra piece of metal (maybe 2 lbs?) in the roof of an si with the sunroof removed as stiffer is better for me (autox, hpde without a full cage). ymmv.

for a daily, none of this really matters, and i'd want a sunroof.

for a race car that you aren't going to go too deep into or you want to be ahead in some areas (though behind in others), it might make a difference for you.

if you are really getting into a preped car, the only difference is the rulebook.
</TD></TR></TABLE>

on the gas tank- i've never weighed the two, but if you look at them the difference is in the flat part, so weight savings here is going to be within a pound or two when both are empty. as far as capacity goes, bigger is better. just put in however much you need to get to the end of the race and not fuel starve.

i've bathroom scale-weighed nearly everything i stripped off the car, but the numbers are at the garage. some of them are in the "how much does it weigh" thread floating around.

 

ive always though about this, but having an 89 si hatch, i dont really relate to it. I have made my car heavier since i have owned it. ls motor, ls brakes, ls spindles, stereo. I dont race it though so im not too worried about it. regardless, if you do the same thing to an hf and a dx the hf is going to be lighter.

 

Well a sunroof assy. weighs 42lbs.
Now take that 42 lbs and move it to the highest point in the car and see how bad it would effect the handling. If you added it to the floorpan in the car it wouldn't matter much because it would be below the COG. Now being at the highest point above the COG........get the picture?
Also the 88 cars didn't have that heavy beam in the doors like the rest did.

 

Another thing the HF didn't have was the rear wiper assembly. Thats what I loved about my HF, looked so clean like that.
