Hello to all fellow Titanians,


I have a 2006 Titan with a blown head gasket that I plan on replacing the FlexFuel engine. The problem is these FlexFuel engines are more expensive than the regular ones on the same block. I was wondering if anyone knows if its possible to use a regular engine to swap out the flexfuel one with moving all the sensors from the flex to the regular. I seen some information online about moving the camshaft sensor from the front to the back but Im not sure that is the end of the mods on the engine. I was looking to find out if that is possible to use a regular engine instead of the flexfuel and what needs to be modified to make it work.

Thank you to all for your help

I`m pretty sure the differences are in the fuel system and ECU itself

injectors, fuel pump pressures to allow E85. and the ECU itself for the tune to run E85.I don`t see why you couldn`t install another block of the same type, swap over all your sensors and go... I have not come across or read any other real differences.
most of the parts I`ve cross referenced in my looking have been the same minus what I mentioned.

if your swapping over your intake manifold and injector rail/injectors, you already have the Flex fuel pump in the tank.

unless there is something major that is different, someone should speak up so we all know...

I am just the opposite, have a flex fuel truck, but changed fuel injectors, fuel pump and added a supercharger. running Uprev for the adjusted tune. I don`t use E85 gas, 93 only. BUT my truck is still recognized as flex fuel when ordering parts.


what information are the yards giving you on the differences?

That is great information and that is what i thought that would be the difference. Thank you!

I think that as long as the blocks are the same size and its only a matter of moving sensors or even the cam positioning sensor that should fit one regular block. The yards are not any helpful as they are often more inclined to selling a more expensive engine.

you will have to make a visual account of the same cam timing covers, and sensors so you have an easier crossover.
assuming your buying the same year engine as what came out...

Check the parts list to see if there's a different camshaft number given for flex v non flex. That's where your acid test of the mechanical dif's would exist.

That is good advice. Does anyone happen to have some link for a parts on these engines?

Has anyone ever done this type of an engine swap that can shed some light on this question. I looked up the parts and it's not really clear from that.

He's out of town until next week, if your replacement engine is later than 06 you will need the harness from that engine send it to Brennan things changed in 07 VCT etc. he will mod the harness to make your install plug n play, having the motors ecu wouldn't hurt. oh also if you are 2wd the ecu & harness must be 2wd sane with 4wd. I found a 2014 2wd complete engine harness ecu everything with very low miles :big_grin: good luck

Something happened to the motor and it's hurt , drives ok but just ok uses around a quart every 800 miles.
I love my Titan and cant wait for the new motor! I think we went to a desert meet together?

Thanks guys. I did the overhaul and it was a pain but well with the effort. I replaced a butt loads of parts to make sure I get the most out of this beast. Also threw on a Rough County leveling kit and some rear spacers. Looks good now just need some beefy tires that would fit the 18s and I'm done.
Here are some pics.
