This video is to help you swap a 2.5 bottom end with a 2.3 disi turbo speed head. This swap is intended to save you some money and help you increase displacement. I will add more info in the next couple of days

Just did the timing chain on my s6, if it ever kicks the bucket ill use this. Thanks man

The 2.5 standard rods are suppose to be good for 450hp

What's the size of the adapter on the feed line

[@tonykarata9398]

I will do this when i blow my 2.3 that i just rebuilt..... i thouth abt dong it but i was my sure if i was going to run into a shit showwww i can get the 2.5 under 350 bucks from my local junk yard ...... they have a ton of them with low miles ....... i paid 1250 for my speed 3 enyway still on a budget ..!!!!

[@gxih4074]

What oil feed line did you use? Also what kind of fitting is that on the oil filter housing?

[@mungewell]

lots of good info, but I think you missed mentioning the oil pressure sensor. If you keep the spin on filter assembly you will want to move the 'green sensor' across - I've read elsewhere that the trigger point is different.

[@Awscheetz]

Seems I'm late to the part, so the block is a closed deck on the 2.5 ? Of did u use the 2.3 block ? I'm wanting to build a swap for my RX7

[@jonstechchannel]

I didn’t watch the whole thing, butttt are you using stock 2.5 internals or do you want upgraded internals or the stock 2.3 internals? What’s the best way to keep it as strong as possible for max power and boost

[@JL-qh5jz]

Your not using the oil cooler from the old speed engine? Isn’t that needed? The one with the coolant lines that sits on top of the oil filter housing?

[@carsandbeatzofficial7545]

Yes I am. I mentioned it somewhere in the video. I advise everyone to use it

[@Marshallbuttholeman]

What was your final hp tq numbers? I just bought a speed6 with a brand new one of these In it with the 2.3 head. Cst4 turbo. Looking for info on what the oem internals are good for.

[@needforspeed6384]

Had a question, im doing the 2.5 swap aswell but from a 2013 ford fusion , i noticed the big timing chain had one blue mark on it , does that mark have to line up with the crankshaft somewhere?

[@davidfernandez62197]

What is the exact motor for the 2.5 I should be looking for this swap looks like a way better option then getting a used speed motor. Just bolts ons and should be fine no ?

Is the oil pan needed to still be tapped for the return of using factory oil cooler?

[@FlipBoji]

Ridiculous question, but can you swap a speed engine into an automatic Mazda? Gen 1 or gen2 ?

[@thecritic8318]

Not without swapping entire engine harness and ecu you would need a doner for the wires to make it work or ebay

[@hlhoover2427]

Hey I'm in TX too. I am going nuts trying to figure out if I need to open up the ring gap on the 2.5l. Should I worry about it running 17 to 20 lbs. boost? I am doing the Molnar rods, so I'll have the pistons out. The Fusion engine engine only has 32K on it, so i;m going to swap the rod bearings straight over. Thank you for all your videos. I learned a lot going into the swap. Thank you for what you do!

@joshuacase8866 yes it is best to regap rings. Shoot for minimum 18 top and 21 bottom

[@driver31111]

@Cars and Beatz Official , Great job, thanks a lot! Got few questions btw.. 1 Fuel system. Is there anything useful from 2.5 motor ? Never had experience with them, but looks like we need everything from Speed(injectors, ramp, Hpfp), isn't? 2 All components like AC compressor, alternator, PS pump, bruckets, bolts, knocking sensor, EGR parts -all that from Speed as well, right? 3 Turbo oil return line adapter for Speed 6 should be drilled to tge oil pan a little closer to the passenger side, isn't? otherwise transfer case will be on the way I guess. 4 Timing cover and all pulleys/tensioner for belt , flywheel coming from Speed too?

[@carsandbeatzofficial7545]

Yes I use everything from the speed fuel system and all components including sensors. If you use the adapter for the oil return it will work for the speed 6 perfectly. Otherwise you can have a bung welded to your oil pan.

[@carsandbeatzofficial7545]

And yes use the speed timing cover , otherwise you won't be able to use the correct pmm.

[@Alabastard]

My question is can you reuse the speed 6 ecu and continue using an accessport for your tuning and datalogging?

[@carsandbeatzofficial7545]

Yes sir you use everything including ecu,and AP.

[@brianbrennan9476]

What size rods did you use? And how did you look them up? Did you look them up for a speed or for whatever the donor block came out of?

[@carsandbeatzofficial7545]

For stock pistons use the 20mm pin size. I went to Fab9 . Look up mazda 2.5 molnar rods

[@jacobhogan3958]

May sound dumb, but what are the advantages of the 2.5 vs 2.3? my guess would be initial cost for the motor for 2.5 is way cheaper than a speed motor. Anything else? Are forged parts around the same price for 2.5 vs the 2.3? also what about the crank? since the 2.5 is naturally aspirated wouldnt it be weaker? thinking about doing this for a buddys speed 3

[@carsandbeatzofficial7545]

Like stated cost is the main thing. Stock internals have been proven to handle around 400hp. Crank hasn't been an issue for higher hp yet. This is still pretty new to speed owners. On this build , the bottom end with forged rods cost way cheaper than a used speed motor. Apart from all that, there is no replacement for displacement. I do like the 2.5 better for it's faster revs.

[@jacobhogan3958]

@@carsandbeatzofficial7545 thanks man! I know my car has forged pistons and rods with a stock crank and is holding 380 hp no problem was just wondering if that applied to 2.5 as well. Seems like a fairly straight forward swap, thanks for taking the time to make a vid about it.

[@Hyperno47]

There is no advantages apart from cost. The L3T DISI has a forged steel crank, the 2.5 has a cast iron crank, the L3T DISI has forged conrods, the 2.5 has cast conrods, the L3T has stronger cast hypereutectic pistons, the 2.5 does not. The 2.5 is a great grocery getter, quite a perky motor actually, but it was never designed for forced induction and the cylinder pressures encountered regarding direct injection.

[@carsandbeatzofficial7545]

@@Hyperno47 apart from the forged crank the disi has I see no other advantage. I've seen every type of failure on the disi. The so called stronger pistons from the disi are a joke and plenty of ring lands fail. The so called stronger rods the disi have are a joke and bend alllll the time for no reason even in well maintained stock vehicles. Have you ever driven a 2.5 swapped speed?? If you haven't you will feel the quicker spool and the car is more enjoyable.

@@Hyperno47 not to mention you can forge a 2.5 bottom for half the cost of an unreliable disi swap.

Question is there any way to pm you? I am currently doing the swap. I want to push atleast 400hp on stock internals. Will I have to open the piston ring gap alittle since I'm pushing boost on a high compression motor?

[@lukaszpasielak3539]

Pulling apart the 2.5 block from the ford fusion. Ive noticed the cam gears didn't have friction washers unless they fell off when i pulled them out. If the 2.5 cam gears didn't have friction washers, would you put friction washers in them while reusing the 2.5 timing components.

No. You would need to put that setup in a speed because the wiring and ecu are meant for the speed head.

[@carsandbeatzofficial7545]

My personal opinion is that the 2.5 timing components are an upgrade from the 2.3. The chain is beefier and it only uses 2 friction washers so it might have less of chance of slipping. It is a direct fit but you must use either all 2.3 components or all 2.5 components.

[@tonykarata9398]

I was just wondering sens the timingg gears look a bit smaller
