A European high-performance version of the LNF with 9.3:1 compression. This engine is also known as A20NFT and A20NHT by GM Powertrain Europe. The LDK engine uses a Gen 3 "sand cast" block, larger oil pan, higher compression pistons, and several enhancements over the LNF. In its stock form it makes ~10 more HP than the LNF and can handle up to 400WHP. To make more than 400whp we would suggest our upgraded rods and pistons. We offer a full forged engine here. This block itself can handle a over 500whp.

Ordering Options:

This comes as a direct replacement engine for a '11-'13 Regal GS with the LHU. If this is the vehicle you have, please select "Regal LHU" when ordering.

This LDK engine will bolt in a front wheel drive LNF Cobalt or HHR SS, we can simply remove the factory Regal vacuum pump and install a block off plate in its place. If this is the route you are going, please select "Cobalt/HHR LNF" so we can set it up properly for your application before shipping.

This engine can also be installed in a rear wheel drive Saturn Sky or Pontiac Solstice GXP, however it will require a LNF head swap. if you want a complete engine, we can do this for you, but you would select "Sky/Solstice LNF" We will simply swap the head for a new LNF head/cam and it will clear your firewall. You will need to reuse your RWD specific balancer, oil pan, valve cover, and cylinder head coolant bleed fitting for the easiest install. The ZFR will require extensive modifications to fit the RWD application. It can be done, but it would cost a few hundred more.

It does not come with an intake manifold or fuel rail/injectors, the stock K04 or a ZFR turbo is optional, however to run the ZFR in a Kappa (Sky/Solstice) it requires extensive modifications. (power steering reservoir relocated, custom wastegate bracket, compressor cover modifications)

You can simply bolt on your factory intake manifold, throttle body, and fuel rail/injectors.

Note: Warranty for this product includes a 1 year manufacturer's defect warranty. If a part fails you must reach out to us, remove the part, then send it back to us for inspection once an RMA (return merchandise authorization) is sent.

ZZP DOES NOT cover exterior costs such as labor, shipping, lost wages, rental car time, etc. 

Power related failures are also not covered under the engine's warranty. 

Important break in procedure:
We recommend running Comp Cams "break in" oil for the first 200 miles. Before you start the car with the new engine, we recommend that you fill with oil, then leave the injector harness unplugged and turn engine over until the oil pressure light goes out, or even better, use an oil pressure gauge. This ensures that you are starting the engine with full oil pressure.

When the engine is running in gear and at light throttle, bring it up to 4500rpm, then coast down to near idle(still in gear), then 5000, then 5500, then 6000, and 6500 each time letting it coast down to idle. This will help seat the rings. Then after a couple heat cycles, start running it under power.

Freight shipping is free for the lower 48 states. Feel free to email for a shipping quote for a different address.

Long block for lnf 08 hhr ss

So far an excellent purchase. Still in break in period but everything has gone smoothly. Cant find a better deal anywhere and a complete update to old platform. I couldn't be happier with zz performance. I've purchased several things from ZZP and haven't had any complaints. Their customer service is excellent (i have been blowing their phones up with questions and not had a single one they couldn't answer) I will absolutely be recommending them to any person I know with an ecotec platform. Thank you very much ZZP Johnny

LDK long block for 2009 HHR SS

Purchased LDK long block without turbo for my 09 HHR SS with 175k on it. Had the engine delivered to my local shop in AZ within 10 days of purchase. My mechanic said it was a straight forward easy motor swap with no issues. Put a little over 1500 miles so far no problems. As always ZZ Performance Thank you!!!
