300hp in a Civic. Best way?

The other thing is the way minimum weights are done in SMF. So with a N/A K24 I could be at 2050lbs, a turbo D16 would be 2075lbs and a turbo or supercharged K24 would 2175lbs. The car currently is at around 2250lbs with sunroof, power Doors, stock seats, airbag steering wheel, some of the A/C system and stereo wiring left. Backseat, windshield washing system, stereo (except wiring under the dash), all the underhood A/C components are gone. 

About to do the suspension rebuild and then later this year hopefully a lot of the weight loss.

Kpro is the only game in town and they sell for about the same new and used (~$800). Yes I know there's another ecu option but their customer service is so ridiculously awful I won't so much as mention their name. 

I forgot about that. It seems like getting the power out of the D-series is going to be a lot cheaper and will let me doing in stages which kind of spreads out the budget. 

I'd argue the best way is to buy a Type R new. 

Good luck getting to minimum weight. I don't know if stripping the interior will be enough. I think you'll have to trade glass for lexan and strip the doors to just the skin.

I am planning on using a decent amount of carbon panels. I'd have to look at the rules again but I am pretty sure lexan and skinning the doors isn't class legal. I am not really sure it is going to hit the mininum weight. 

Nothing else to add other than I'm a big fan of built d engines, they're so lean and simple. Very cool looking in the engine bay, plus relatively cheap to build since they're usually thrown out for b or k swaps. 

You may want to think through transmission and gear options at some point. LSDs seem harder to come by for d-series, but a d2b adapter allows you to install a b series transmission. Cable vs. Hydro clutch might matter depending on how old your chassis is. Chris Tybor at WDR racing in TN is the go-to guy for d-series transmissions. 

Not sure what chassis you have, but almost anything EF can hit the 2k weight mark really easily-even the EG hatch should get you there. See below for chassis weights.

Either D or B allows you to stay OBD1. Crome is widely used and still free. Honda Tuning Suite currently has a lot of development effort behind it, Neptune is commonly used by tuners and like Byrneon said, the S300 is pretty common too.

"Usually thrown out" means "hard to find" in my experience.

I had a WTB thread on RX7club for 4-lug FC parts.  Was willing to buy at 2x the value of 5-lug FC.  Only had ONE person respond, everyone else was like "lol I scrapped that E36 M3"

Scored a pair of good condition 4 lug front hubs for $50 plus shipping and we both felt like we made out like bandits.

You know what "usually thrown out" means?  It means air pump pulleys for '70 Mustangs selling for $2000 on eBay.

While ranting:  The D17.  Dammit Honda how could you take an easy to work on engine and BERK IT UP SO HARD???

J35 swap?

I don't think they're comparable to your situation. They made a lot of d series cars, and they're still fairly "new" in the grand scheme of things. It's closer to the 1.6 in the Miata, but more plentiful. I can find 1.6 parts all day and for cheap even though they're the unloved engine.

Built a 1995 Civic with a D15 for the 2008 GRM Challenge. Used ebay turbo components with a volvo t3 turbo,  and a tune. It would drive every day like that, run 12.1s all day in the 1/4, and autox/HPDE just fine. That was also with the car at like 2000lbs

I'm no honda expert, but K-series swap with a turbo?

I kind of thought about it but being a teen in the Sport Compact Car era I always wanted to do a b-series swap or d-series build. 

I can relate to this era, but I now have a stock DD k24 in a TSX and I would have considered it quick 20 years ago, yet its bone stock and well worn. I had a good friend with a b swapped stripped civic and remember it fondly. I'm really sold on the k platform with its current aftermarket and parts sources (crv's, accords, accuras etc) 

I find the motoiq site painful to read due to spreading the articles over a billion pages, but sometimes they have quality tech. Check out the 300 hp NA pump gas k build, I would say its a "cheap" bolt together affair, but the costs are relative. They definitely give you a well thought out recipe for pump gas NA at a reasonable budget.

part 1,  Part 2,  Part 3,   Part 4,   Youtube summary  

Adding low boost or E85 may get you a little more attainable hp for a little less cash (they lost huge HP with a cat, I'm no longer a fan of megaphone exhausts on hondas) 

I won't comment on size or weight as I don't really know but will say I like the evolution of honda towards the k series.

My god the d17 is awful. I currently dd an ‘04 civic.  It’s reliable and all, but a far cry from the civics of the ‘90s 

I'm pretty sure cross manufacturer engine swaps are allowed in sm now.

Also XS is a little more open than SMF. But drivetrain is open.
