Anyone pulled their current motor from their coupe and swapped it into a hatch? Trying to get a rough estimate how much faster the times would be swapping your exact coupe setup into a hatch chasis.

For example...

160 whp GSR Swap in a 96-00 Civic Coupe => 160 whp GSR Swap in a 96-00 Civic Hatch.

How much faster (roughly) is the hatchback now going to run now with the smaller chasis compared to the coupe chasis? Reason why I'm asking is, I was origionally running 13.5 in my EM1 w/ITR swap and wondered what it'd run if I swapped my setup in a EK hatch?

 

I pulled my b18c turbo from a 96 ex coupe and put it in a 92 dx hatch. Both had full interior. The motor was tuned with hondata when it was in the coupe and it made 232 whp. I ran a 8.29 @ 85 in the 1/8th. I pulled the motor out and put it in a hatch. I DID NOT have the hondata installed in the hatch. I used a FMU, but I do plan on installing the hondata in the hatch and getting it re-tuned. With the hatch I Ran a 8.33@ 85 in the 1/8th. I know for a fact when I do get the hatch tuned, I will be in the mid 7s. It is definately worth it imo.

 

anyone else? You ran slower in the hatch than you did in the coupe... thats not very convincing..lol

read his post, he didnt have the hondata tuned.

 

eric, ur building a NA car i would never ever run a 2500 lb coupe in NA configuration. even with weight reduction its still heavy compared to a hatch.

 

about .3 to .5 sec faster in the hatch

I know, thats what I'm debating on... I was gonna buy a $7000 quad this late summer but I got to thinking about it and maybe I should buy a hatch and use the money to do something like yours in a way so I can get those faster times.. $5000 for a hatch and $2000 for a trailer set aside could prolly buy something reasonable (haven't really looked around yet) then I'd put my Si Coupe back to stockish form and daily drive that again or sell/trade it in on something else...

 

u must have read about the reason i swapped to a hatch. i guess because i was tired of my daily driver breaking axles from track abuse. i got my trailer for 1800 brand new down by boise.

 

First of all hatches and coupes of the same year and trim do not have that much of a difference in weight. For instance a 92 dx hatch is 2178lbs, the dx coupe is 2240lbs, and the dx 4door is 2275. What the heck is the big difference. Yes in the 1320 it may slow you down a little, but not enough to pick one over the other, unless you race 4 $$$$$ which most Honda guys don't.

 

u have a valid point but who the **** cares about comparing trim levels???? he drives a 99 civic SI, that right there is 2560 give or take. now drop him into a 92 CX or VX that weights 2080lbs bone stock and u lost 500lbs. i picked up my hatch for $1300.

 

First of all if you read his first lines carefully, you would see that he is asking a general question. He asked if anyone has taken an engine out of a coupe, and put it in a hatch. He didn't say has anyone taken it out of a 99si and put it into a CX. Now in that senerio it would be a huge difference in performance, but the question was general.

 

sorry about being so braud... What I was thinking is swapping motors with a 99Si into like a 99CX Hatch

* 1 2 NV: What header are you running? I'm thinking about upgrading headers this season and I'm stuck on what header I should run..

 

would swapping everything over from my Si to a 99 DX hatch be benifitial? whats the weight difference I'd save in chasis weight? How much lighter is teh 99 DX hatch to the 99 Civic SI

Lets put it this way, when the coupe had the fmu, it was running 8.80s in the 1/8th. The hatch ran 8.30's with the same fmu setup.

 

so any basically with any hatch whether its 92-95 or 96-00 you're ideally gonna shave off roughly a half second on your time?

 

SI coupe 2601
CX hatch 2359
DX hatch 2388

Don't count us coupes out completely. Coupes are sexier We just have to make more power to beat you hatches

 

the ladies jock the coupes more than the hatches

 

I wonder about the weight on that dx/mt hatch at 2388 lbs. I did very little weight reduction to my 98 (virtually identical), and have had it on scales a few times (autox car). It weighed between 2220 and 2239 every time. That's with full stock interior, stock motor, removed spare tire, and race wheels/tires (light but not that light..), and 1/4 tank of gas.

A friend's 92 VX did weigh very close to 2094 lbs though..

edit: and I know there hasn't been any "funny business" with this car because I bought it new..

96-98 hatches arent that much lighter than coupes

 

and the weights that were given in that list, don't include your extra weight from the swap. If you not trying to set records, i'd stay with the coupe. spend your money and time to pull some more hp from your current setup.

 

i agree 96-00 coupes and hatches arent too far apart from each other especially if u do some weight reduction to switch wouldnt be worth the time and effort unless u were gonna go with a 92-95 hatch in which case u would be 300-500 lbs lighter

Hell yeah and those pesky CRX's damm lucky HF guys lol

 

I'm not sure but I think when you go from a D series motor to a B series you gain between 50 to 75lbs. Also I feel what u sayin. Some of the same people that want to take a motor ot of 1 car to put in another car ain't even racing for $$$$$, or trying to set a record. They just running up and down the street hitting VTEC every chance they get, and lining up occasionally at the weekend races. I know some personally. Now taking a motor out of a 99si into 88hf crx ain't that bad.
