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.

FAQ

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.
