Infiniti G35 Engine Replacement in Phoenix

Both the coupe and sedan share the same engine family, but "VQ35DE from a G35" is not a single part.

The Infiniti G35 was the first generation of Infiniti's compact sport sedan and coupe, built on the Nissan FM platform and powered exclusively by the VQ35DE 3.5-litre V6. Both the sedan (2003–2006) and the coupe (2003–2007) used the same engine family, which makes identification straightforward in principle.

In practice, the coupe and sedan diverge in transmission options, wiring harness part numbers and in some cases the engine mounting hardware. The manual-transmission coupe and the automatic sedan are different enough in their surrounding components that a "VQ35DE from a G35" is not a single part. A 2006–2007 Rev-up higher-output variant also appeared in the coupe, with different internal specifications that matter for a direct replacement.

For buyers of the 2007–2008 second-generation G35, the engine changed to the VQ35HR, a different engine entirely. Confirming which generation you have before requesting a quote avoids the most common misorder on this vehicle.

Coupe and sedan are not the same order

The G35 coupe and sedan both use the VQ35DE, but they differ in transmission options, wiring harness part numbers and some mounting hardware. A manual-transmission coupe and an automatic sedan are different enough in their surrounding components that a supplier needs to know which one you have.

The Rev-up variant that appeared in 2006–2007 coupes adds another layer. It has different internals from the standard VQ35DE and is not always clearly distinguished in used-engine listings. Confirm which variant you need, and supply the body style, transmission type and VIN.

Where Infiniti G35 orders go wrong

  • Coupe and sedan VQ35DE applications differ in wiring, transmission hardware and some mounting details. Specify both the body style and the transmission.
  • Manual and automatic cars use different flywheel and torque converter arrangements. An engine pulled from an automatic may not bolt to a manual transmission without additional parts.
  • The 2006–2007 coupe Rev-up variant has different internals from the standard VQ35DE and is not always distinguished in listings. Verify which variant you need.

None of this needs to be worked out on your own. The Engine Finder asks for the year, model and trim and does the identification from there. The engine code field is optional precisely because most people do not have it.

Check availability for your Infiniti G35

Year, trim and ZIP is enough to start. If you have the VIN it removes the guesswork entirely.

Which vehicle is the engine for?

Year, make and model get us most of the way. Trim matters more than people expect. A 2008 Civic is a different engine depending on whether it is an Si.

LX, EX, Si, Type-S, V6. Whatever is on the badge.

Know your engine code? Add it here.

If you do not, leave these blank. That is genuinely fine. Working out which engine a vehicle takes is the part we do. Here is where the code is stamped if you want to look.

We do not confirm that an engine fits your vehicle until it has been checked against it.

Common questions

Is the G35 engine the same as the 350Z?

Both use the VQ35DE, but the applications differ in accessory layout, sump configuration and mounting. A 350Z engine is not a direct bolt-in for a G35 without addressing those differences. Supply your body style, year and VIN so the supplier can match the correct application.

What is the Rev-up engine?

The Rev-up is a higher-output variant of the VQ35DE fitted to certain 2006–2007 G35 coupes. It has different camshafts, pistons and other internals that give it more power. It is not always clearly distinguished in used-engine listings, and fitting a standard VQ35DE where a Rev-up was specified can cause engine-management issues.
