you can run 12.5 compression on 87 iof your tune is really good. hop on d-series.org

highstrung? no it wont be high strung. think about it. d15b7 makes 102 stock crank. Y8 head alone brings that up to a calculated 120, just from the headflow characteristics and increased compression,. that cylinder head also has teh best quench pad for VE. a mild cam will net another 5 or so horsepower. what do you have? you have a motor with OEM parts that has similar characteristics to teh stock B7 setup, but it simply has more power across teh entire spectrum

not by any means high strung, and the Y8 head adds about 10 peak torque, and some of teh low and mid range is increased over 15 tq

Im thinking your one of those people that lean towards a swap then to deal with the stock single cam

 

good info thanks.
here is some good info for you guys.

I hope this info helps ya and good luck there is a s load of things ya can do i liern new stuff every day Ltr.

 

Thank! Very informative. Will come in handy. UHmm, I'm not sure which civic generation to buy for project. I'm thinking either 5th or 6th generation. Some of you were saying that the 5 generation might be eazy to swap and install than the 6th generation? Possiblity much cheaper too?

 

I think the d series is great for one of two things: either turbo it or just get groceries. Engine building is tedious work and for the cost of aftermarket parts and the time spent in the garage, a built N/A d-series just does not sound even remotely worth the effort to me. And, yes, I consider anything with a 12:1 compression ratio high strung, and you'd have to be a tard to put 87 octane in it. I'm not trying to be a hater, that's just the way I see it.

What do I have? Bone stock 99-spec b20 with a gs-r transmission. I consider this an upgrade from my previous motor, which was a built b16A with BC spec 3+ cams, omni valvetrain, decked head, etc, etc, etc. When it comes down to it, I'd rather have the car go when I hit the pedal rather than having to drop two gears and scream like a banshee to pass a minivan on the highway.

 

The swap process for 5th gen and 6th gen civics is pretty much the same. The main difference is that the 6th gens require a different rear bracket engine mount. For a 5th gen, all the stock integra mounts work for swapping a b-series.

Performance-wise, the 5th gen is a little lighter, but it's not going to make a huge difference. As I mentioned earlier, the 5th gen EX does have the added benefit of rear disc brakes and a stock rear sway bar (which makes aftermarket or ITR sway bars easier and cheaper). Ultimately, the car you pick doesn't make a huge difference performance-wise if you're swapping. Some of them are lighter than others (the DX is the lightest 4-door model), some have more options. But I would just get whatever you get the best deal on.

 

I was hoping to get a civic which's 4 door standard. I'm newbie so i was thinking to get something eazy to work on. I know the newer civic probably need must modification on engine swapping. I was thinking to go for b series engine for now. I don't have much to spend on. Just want to learn and understand as i build along.

There isn't any places around my area does engine building. I know it needs alots of work and proper tools to build it, so i was thinking to just swap another one. The link i posted seem to be o.k but will have to check by and see what they actually selling and policy about their businesses.

Would be better to swap another engine than building from the stratch. Would be eazy that way for starter like me? I haven't brought a civic as yet so I'm still checking around. They are alots of HOnda civic for sale in Ontario for cheap and the mileage's high. I think i might go for 5th generation since it the parts might not be expensive than the 6th and 7th generation.

Does anyone here knows about engine swapping. While I'm doing this. Is there anything else i need to about it? Do i need to change the ECU or configure it, or do i just have to plug and that it?

 

Depending on what you're swapping to, and what you're swapping from, you will have to change the ECU, along with the wiring harness. Shouldn't have to actually mod the ECU unless you want to.

 

The H series was in Preludes. It had like 230HP stock. Good engine, but it's hard to do a swap with an H.
I've seen boosted H22s 350HP at the wheels. They're along the same lines as a K20, HP wise. :irock:

 

I know what the H and F series are, I simply dont know specifics like what mounts and brackets are used in a civic swap

H series suck in comp[arison to a K series actually

a B20 vtec will rape a K20 though (B20 block, new rods, B16 head)

 

Yes, an engine swap is a lot easier (and a lot less potential to ruin a perfectly good motor) than building one.

Do a search (in the bar near to top of the page) in the hybrid forum for all the information about various swaps and how-tos. It's all been covered a thousand times.

But the basic run down for a b-series swap into a 5th gen civic is: motor, trans, ecu, wiring harness (not 100% necessary, but nice to have), shift linkage, motor mounts, axles. Research up before hand, and the swap can be done in a weekend. After you've done it once or twice, it can actually be done in a day
