Honda with 4G63?

[stock1g4g63]

Hey guys, I know it's probably been done before, but I've heard of a guy who has a 4G63 in an MR2. I was thinking, how feasible (costs vs. speed) to put a 4G63 into something small like a CRX or FC3S (2nd gen RX-7) for weight purposes?

I know people are putting B16's into CRX's and are running pretty quick with a 160hp engine. Now, since the 4G63's in the 2g's put out about 210hp stock, wouldn't that make a big difference in the CRX just in stock form. Now with a few basic bolt ons, and turbo upgrade, imagine a 270-300 hp engine in that tiny little thing. Let me know what you guys think, and if anyone knows what I could be looking at spending. I know it's a lot of $$$, with custom motor mounts, and drivetrain and all that, but an estimate would be nice.

if possible, that sounds like a badass idea. a three or four hundred pony rex would wreck it, definetely. though I dont' think you're going to get much support in this forum, unfortunately. board's full of closed-minded fools that ostracize you for simply uttering the word 'honda'

 

[Libila]

I think a build 6 bolt in a rex would be awesome. But like the guy above me said, your probably not going to get much help here (Honda Haters). Go to www.honda-tech.com and ask around there. Good luck

right there, can't wait to see how it turns out.

nothing wrong with the 13b in the fc3s or the 3sgte in the mr2.

the crx would be a good choice since its light and the engine it has sucks. any little civic hatch actually.

Take that back!

I love the D16A6. The 1.5's are nothing special, but the A6 kicks ass.

Cheaper, easier and more popular to swap a B16A or B18C5/1 than to do a 4G63T swap. Go with whats easy, unless you have the time and money.

 

[krustindumm]

turbocharging the SOHC is easier than a swap, and more torque, and cheaper. Plus you get the cool spooling and BOV sounds, and after all, it is all about the cool factor

yeah, i'm rebuilding (or putting back together) krustindumm's civic right now. The thing is so simple, its a weekend swap if ya blow an engine. (which he did, quite well too)

 

[stock1g4g63]

Well, let's say I theoretically swap a B16, obviously making power out of those (Nitrous not included) would require more money, I.e. turbocharging it, building the motor, yadda yadda. The 4G63 makes power so easily from basic bolt ons consistently. A CRX with a turbo'd B16 would costs what (turbo kit, labor, building the motor)? As apposed to a CRX with a 4G63, injectors, fuel pump, 16g and intercooler. Upping the boost with a boost controller. And for the RX-7, I like the rotaries, but it seems like power would be more consistently pulled from a 4G63, I use to have an fc3s, and it game me a butt-load of times more problems than my DSM, not to mention finding people to work on them. Oh, and as for the MR2, I was talking about the 1st gens. But thanks for the input guys, i'm not trying to make this a bashing contest or an argumentative one. Just post your opinions. Thanks.

any civic motor = t3h suck. if you think otherwise, you are pulling the wool over your eyes.

just do it to a colt. why bastardize a 4g63 like this?

 

[wishihadatalon]

im surprised you guys have never heard of this. it has been done. i think it ran 9s but then rules change so the motor had to be same make as car. put a s2k motor in it and it ran 11s. it was buschars crx. i believe it has the 4g63 in it agian though

 

[krustindumm]

I believe you are the one who is blinded by a superiority complex.

Honda has a nasty habit of overkill, my motor will support aproximatly 300whp with a stock bottom end. While that may seem low compared to your numbers, it is an over 300% increase from stock. Mild upgrades (pistons, rods, pin it if you feel unlucky) and you can do 400+whp. All this from a 1.6L SOHC non-VTEC. The transmission will also take all the abuse, the clutch does need upgraded, as do the axles, if you want the power to go to the ground.

The DSM motors are nice, otherwise I would not bother posting here, but claiming that all civic motors suck just to feel better about yourself is pretty low. After all, I have yet to see a F1 engine with Mitsubishi on the valve covers.

Personally I dislike the B16. The B18 is okay, but still not my favorite. My problem with the B16 is that Honda shortened the stroke to increase the rev limit, not the best way to do things since that also reduces torque. The B18 has a longer stroke, but increasing displacement is also not the right way to gain power. I have never really liked VTEC (except for a 3 month phase I would like to forget), so that is also a hardpoint of mine.

I have yet to see Honda be a major competitor in F1 recently...

I do not quite understand why you would swap out the rotary, but if you wish to do it, go for it!

look what I found....

Anyways, I'm not a honda basher of any sort, and if anyone is going to try to bash on honda's or any other car, please refrain from posting. At least there's only been one immature person on here...

Anyways, about the rotary, they're really really nice, just that I feel more power can be extracted from the 4G63's. More reliably anyways. However, the rx-7 trannies will murder the DSM trannies, so bleh. Anyways, the reason I'm saying this is because I would like somethign different, but I don't think i'm ready to give up my DSM heart yet I'm on the verge of just giving up and buying an NSX.... But then again, I'm more than likely going to turbocharge that too.... heh

 

[OverboostXS]

Hondas and dsm are two totally diferent fields. AWD TURBO and a NA that revs high and is damn powerful are way different sides of the spectrum. For the power those engines make is pretty amazing sometimes. Dont get me wrong no company can beat runnin 11.7 and still driving to school everyday 12 miles away.

 

[stock1g4g63]

On a side note, John Shepherd is my inspiration for staying with DSM's. I don't think any other import has beaten his DSM (street legal that is). I think he ran something like an 8.79 ET with 156mph trap, give or take. Not to mention that car is still sometimes used to go to the grocery store, has no weight reduction beyond a hood, and still gets 20mpg. DSM's, I salute you. *a single tear rolls down my cheek*

the titan motorsports supra is his only competition... i believe they are still faster currently.

 

[klipzedgsx]

did anyone else notice how dumb honda people are, this one guy said that it will be cheaper easier and make more power to put in a b18 all motor. no cheaper and easier yes but to say a hond motor will keep up with a 4g63 is just nuts

 

[stock1g4g63]

Well, there's no need to go around bashing people guys . Seriously.... But from what I've concur, it might be cheaper to bring a street legal crx with a DSM motor into the sub 11 second range, then it would be it would be to bring a CRX with a B16 or B18 into the same range. Granted, the DSM swap would obviously cost more and require more fabrication, but the costs of building the B-series to handle a turbo, not to mention the turbocharging costs (turbo kit, labor) would surpass the cost of simply swapping in a 4G63 and putting some bolt-ons on right?

Does anyone know the weight of the CRX, and of the different hatchbacks?

Also, how much do our DSM's weigh? I know the first gens are lighter, the 2g's are around 2900 right?

Just thought I'd point out that all the Honda motors I know of have floating cylinders and are pretty much maxxed out for block strength somewhere below 400hp at the crank. One guy I used to talk to on a Honday forum slowly worked his Integra up to 427whp in a process of breaking 4 blocks and finally building one with block filler in the cylinder walls and some kind of plate that supports the tops of the cylinders. This is the first Honda engine he's been able to reliably make that kind of power with.

 

[ABK]

yeah #### hondas. I used to drive one it ####en broke down so much for realibility. DSMs will rip on hondas all day long, especially with D16 wtf is that ain't shit. atleast give a b16a1 but even that my cruiser heavyweight maxima with nothing on it will rip on it all day long too.

You might not want to start off that way, ricers are everywhere. tbTalonES94 (from this forum) has a N/A talon with a CO2 intake sprayer. You could also read ABK's last post.

But from what I've concur, it might be cheaper to bring a street legal crx with a DSM motor into the sub 11 second range, then it would be it would be to bring a CRX with a B16 or B18 into the same range.

Does anyone know the weight of the CRX, and of the different hatchbacks?

88 CRX Hf was about 1900, 91 CRX Si was about 2200, the rest are in between. The 1G CRX's were all lighter (84 Hf~1600, 87 Si~1800).

You are right the 4G63 swap would probably be faster than any 1.8L VTEC swap into a CRX, it would also be cheaper since those motors are heavily overpriced. The B can make alot of power with a turbo w/o internals, so there is not much prep work needed for boost.

This is the first Honda engine he's been able to reliably make that kind of power with.

It is called an open deck design, and this must have been 2-3 years ago, because no one is having those problems anymore. The plate is a block guard, and it is not used in most high power applications. Resleeving is popular, and pinning is gaining popularity.

To summarize all my posts: the 4G63 will be cool, but the Honda motors are pretty good to.

Some day I intend on putting a 6-bolt 4g63t in the MK1 Mini shell I have We'll see how that goes.
