K-Swap Guide: Fitting a K20A into an EG/EK Civic Chassis Without Hitting the Hood
The moment you drop that K20A into your EG or EK Civic engine bay, you realize the factory hood isn’t going to close without some serious negotiation—but with the right mount kit and a few clever tricks, you can make this legendary engine fit without cutting a giant hole in your hood.
K-swapping an EG or EK Civic is one of the most rewarding upgrades you can do to these lightweight chassis. The K20A delivers strong power, modern reliability, and huge aftermarket support. But here’s the challenge—that beautiful engine sits taller than the original D or B-series, and the hood clearance issue can be a real headache if you don’t plan ahead.
Here’s the good news: aftermarket companies have spent years solving this exact problem. With the right mount kit and a few modifications, you can fit a K20A into your Civic hatchback without sacrificing that clean, stock hood look.
TL;DR
The key to fitting a K20A under an EG or EK hood is choosing the right engine mount kit. Hasport’s EKK2 kit uses an EG/DC2 subframe, positioning the engine slightly further back for better clearance. For EK chassis with the stock subframe, Innovative Mounts offers a direct bolt-in option. The DC2K2 raised-height mounts add .75 inches of ground clearance by taking advantage of the Integra’s taller hood line, though EG/EK fitment requires hood skeleton cutting. A K24 swap requires more attention to clearance than a K20.
Key Takeaways
- Mount kits determine clearance—different kits position the engine at different heights and angles in the bay
- The Hasport EKK2 kit positions the engine further back, improving hood clearance, axle alignment, and radiator space
- EG Civics need EG-specific mounts—EK mounts won’t work in an EG chassis
- The power steering pump often causes clearance issues and may need to be deleted
- Hood spacers or cutting the hood skeleton can gain an extra few millimeters of clearance
Understanding the Clearance Problem
The K-series engine sits taller than the original engines in EG and EK Civics. The cylinder head and intake manifold take up more vertical space, and the fuel rail is often the first thing to make contact with the underside of the hood.
The problem is worse on some chassis than others. EK Civics generally have less hood clearance than DC2 Integras, which benefit from a taller hood line. K24 swaps are even more challenging than K20 swaps due to the taller block, though all K-series heads share the same height regardless of displacement.
The mount kit you choose has the biggest impact on whether your hood closes or not.
Mount Kit Options for Hood Clearance
Hasport EKK2 Kit (EK Civic with EG/DC2 Subframe)
This is the most popular setup for EK Civic owners. The EKK2 kit uses the EG or DC2 subframe, steering rack, and lower control arms. This positions the engine further back in the engine bay, creating more clearance for the radiator and air conditioning compressor.
The dual-height adjustment optimizes engine placement for better alignment, ground clearance, and compatibility with headers and intakes.
The engine sits further back, which can help with hood clearance and keeps the axles at a straighter angle.
Hasport EKK1 Kit (EK Civic with EK Subframe)
The EKK1 kit is the older design that works with the factory EK subframe. It’s simpler since you don’t need to swap subframes, but the engine sits higher in the bay.
The EKK2 is strongly recommended over the EKK1 for better oil pan clearance, axle alignment, and overall fitment.
Innovative Mounts B90050 (EK Civic with EK Subframe)
Innovative Mounts offers a billet mount kit that allows K-series swaps into EK Civics while keeping the factory subframe. No cutting, no welding, and no subframe swaps required.
Key specs:
- Fits 96-00 Civic with EK subframe only
- Compatible with K20A, K20A2, K20A3, K20Z1, K20Z3, K24A2 (K20 transmission required)
- 75A (street), 85A (track), 95A (extreme), or solid billet bushing options
- Not compatible with K24 transmissions
The B90050 kit lets you keep your factory EK subframe, though it positions the engine differently than Hasport’s subframe-swap design.
Hasport EGK1 Kit (EG Civic)
If you’re swapping into an EG Civic (92-95), you need EGK1 mounts specifically. EK mounts won’t work on an EG chassis because the subframes are different.
Hasport DC2K2 Raised-Height Kit (For Extra Clearance)
This kit is specifically designed to take advantage of the taller hood line of the 94-01 Integra. It raises the engine by .75 inches, increasing ground clearance for both K20 and K24 engines.
For EG and EK Civics, the DC2K2 kit can be used, but:
- Hood skeleton cutting is required (the engine will clear the hood itself, but the internal bracing needs modification)
- The power steering pump will not clear the hood in EK or EG chassis
Hood Clearance Modifications
Even with the right mount kit, you might need to make a few modifications for perfect clearance:
Hood Spacers
Simple hood spacers (washers or dedicated spacers at the hood hinges) can give you an extra few millimeters of clearance. This is a popular solution when the fuel rail or intake manifold is just barely making contact.
Spacers are a cheap and reversible solution, but they do change the hood gap and can affect aerodynamics.
Cutting the Hood Skeleton
For setups using the DC2K2 raised-height mounts, the hood skeleton—the internal bracing structure—needs to be cut to clear the engine components. The outer hood skin remains intact, so the car looks stock from the outside.
This is a permanent modification, so plan carefully before you cut.
Power Steering Deletion
The power steering pump is often the component that creates clearance issues, especially on K24 swaps where space is even tighter. Many K-swap builders delete the power steering entirely:
- The EG Civic chassis doesn’t support power steering with the DC2K2 mount kit
- Without PS or AC, you can run an EP3 idler pulley with a 50.5″ belt (K20) or a 52.2″ belt (K24)
What About K24 Swaps?
A K24 swap is trickier for hood clearance. All K-series heads share the same height, but the K24 block is taller than the K20 block. K24 swaps generally need:
- Raised-height mounts to gain clearance
- More aggressive hood modification
- The power steering pump deleted for best results
However, with the right Hasport mount kit, a K24 will fit in an EK without cutting a large hole in the hood. Some builders have fitted K24a2 engines into EKs using Avid mounts with excellent clearance results.
The K24 is possible, but it demands more careful component selection than a K20 swap.

Real-World Tips from Builders
“If you’re running a K24 with a K20 head (a K24/K20 ‘Frankenstein’), it’s the same clearance as a normal K24. It’s the block that matters, not the head.”
“The EKK2 mounts helped me get the oil pan higher and the axles aligned better. I strongly advise using the EKK2 kit over the EKK1.”
“Even with Hasport mounts, the TWM throttle bodies will hit the hood for sure. It’s not the motor that hits, but the fuel rail. Hood spacers on the latches can solve this.”
“The DC2K2 kit works in EG Civics but you’ll need to cut the hood skeleton and the power steering pump won’t clear.”
Frequently Asked Questions
Will a K20A fit under a stock EG/EK hood?
Yes, with the right mount kit. Hasport EKK2 or Innovative B90050 mounts position the engine for proper clearance. The EKK1 mounts may require hood spacers.
Do I need to cut the hood for a K-swap?
Not necessarily. The EKK2 mount kit fits without cutting the hood. The DC2K2 raised-height kit requires hood skeleton cutting, and some ITB setups may need spacers.
Which mount kit gives the best clearance?
The Hasport EKK2 with EG/DC2 subframe offers the best balance of clearance, axle alignment, and radiator space. It positions the engine further back in the bay.
Can I keep power steering with a K-swap?
Yes, but check your mount kit. The DC2K2 kit doesn’t support power steering in EG/EK chassis. The EKK2 and EKK1 kits work with power steering, though space is tight.
Is a K24 swap harder than a K20 for hood clearance?
Yes, the K24 block is taller. It requires raised-height mounts and more careful clearance checks. Some builders have fitted K24s to EKs with good results using the right mounts.
What’s the best transmission for an EG/EK K-swap?
RSX or 02-11 Civic Si manual transmissions are the most common and compatible with the major mount kits.
Final Thoughts
Fitting a K20A under the hood of an EG or EK Civic without cutting a giant hole comes down to one decision—choosing the right mount kit. The Hasport EKK2 with an EG subframe is the proven solution for EK owners who want proper clearance, axle alignment, and a clean install. For EG owners, the EGK1 kit is the direct fitment option.
Here’s the truth about K-swapping these classic Civics—you either choose the right mounts the first time, or you’re chasing clearance issues, hood rubbing, and alignment problems for weeks. The mount kit is not the place to cut corners.
The investment in quality mounts pays for itself in peace of mind and a finished build that looks and drives like it came from the factory. Whether you’re building a weekend warrior or a track weapon, the K20A in an EG or EK is a combination that’s hard to beat.
