The EFR is a bolt in turbo that retains the factory exhaust manifold and downpipe. It is a water cooled, dual ceramic ball bearing, extended tip turbo with built in wastegate/bypass valve, and uses a custom exhaust housing available exclusively from ZZPerformance.

So what makes this turbo so special? Easy answer. Same spool as stock, fully bolt in to factory parts or aftermarket parts setup for the factory turbo. Power levels comparable to our 256 turbo kit.

Model: This will select what size turbo you are ordering.

6758: This is the turbo we have been selling since 2012. It has a 54mm compressor wheel and spools early and quick. This is an excellent choice for daily drivers and road course cars. Full bolt ons and e85, Matt Meekhof made 540whp with this turbo.

7163: This turbo has a 57mm compressor wheel and supports up to 50 more horsepower compared to the 6758. The 7163 also adds an amazing new feature. The center housing is actually made from aluminum for reduced weight and better cooling characteristics. This turbo is a great choice for drag racing, or more modified cars when looking for the highest power numbers while still retaining quick response and spool time.

Regal note: Must use an aftermarket or ZZP upper charge pipe that has a coupler connection to the turbo because the factory charge pipe bolts directly onto the turbo.


Is it a full bolt in?

Yes. We include longer oil lines and modified coolant lines to accommodate the large size of the turbo. New bolts and a wastegate bracket. The turbo mounts up same as stock but being larger we include parts to clear the larger body.

Why is there smoke coming from the exhaust?

This can happen when there is a restriction in the turbo oil drain line. Check your oil return line to ensure that it is not kinked. Slide the heat sleeve all the way up and then all the way down in order to inspect the entire drain hose.

How much power will I make?

Depends on mods and your tune. Basic bolt ons(intake, downpipe, 1.0 pcm) with 93 octane you can expect approximately 350whp which is 50+whp over the stock turbo, add Stage 2 LNF cams and it can achieve 380whp, e85 over 400whp. We have achieved 450+whp in a few customers cars with the following ZZP mods: IC, charge pipes, ZFR 6758, downpipe, 3" catback, Ported head combo with Stage 2 cams, and 82# springs/retainers. With this turbo Matt M achieved 540whp using E85. His car has all of the ZZP bolt ons.

Do I need to tune after install?

We always recommend getting a tune specific for the ZFR, however if you run the 6758, you might be ok without one. However the 7163 turbo comes with a high pressure wastegate and will require a retune. Scanning is always recommended on any performance car and will most likely be beneficial.

Will it fit on my car with XXX brand parts?

This turbo bolts to any parts that work with the factory turbo.

Do I need to do anything special?

Premium fuel is required.

How long is the install?

For us it takes 4 hours. For many users w/o good tools or who are unfamiliar with the car, it may take 5-8 hrs.

What cars will it fit on?

It will bolt up to any FWD LNF based car but we have only test fit on Cobalt, HHR, and '11-13 Regal.

Does not fit the Sky/Solstice.

EFR bypass is the same as the stock K04, so a blockoff plate will interchange.

Great ! This bolted right on my existing manifold and intake also came with everything I needed to swap out my k04. Included was a new oil feed line, turbo to downpipe bolts, valve-cover breather pipe, nicely coated black coolant lines, helpful instructions and a zzp sticker !

I bought the 6758 for my 08 hhr ss. Getting the stock k04 was kind of a pain in the *** as most of the bolts hasn't been touched since the car was made. I also don't have everything I need but being a marine, I adapted and overcame. Putting the new turbo in was alot easier then I thought it was going be. As soon as I get my tune from Matt I will update on difference in performance which from the looks of it will be substantial.

Great All Around Turbo Upgrade!

I haven’t put it on my car yet but a friend running it made almost 500whp on e85 with everything I’ll have on mine car. Sadly I’m stuck with 93 but I know it’ll be a huge difference and run great. Spool time isn’t a huge problem like some may say. It does come in slower but not huge.

For the price, it would've been nice to get all the gaskets needed. Fit & finish, some sanding had to be done to allow it to fit... (bummer) Is mentioned on several forums... Bit if an issue tuning due to the waste gate but is being handled well by the knowledgeable tuner. A coolant leak from two cracks on the coolant feed input due to a poor casting issue showed up. Which is being assumed more towards an installation mistake instead of the possibility of a part issue. I am a mechanic/fabricator by trade and always do my best to be by the book on specs. I have the torque spec for the nuts and bolts for this install and all of the hardware can and is to spec. Even brand new parts of any kind can and do have faults.... Every mechanic knows this. The company is working with me on this to some degree and asked me to send it back to them for repair, which I'm in the process of. We will see how it goes from here in regards to a revised review. Let it also be noted that this is the FIRST problem with any of the MANY parts I've purchased from ZZP. As for power, we are still in the tuning phase...
