Ok so some of use know that you can put a 2.3 head on a 2.4 block and it will make somewhere aroud 200hp (flywheel hp)

so i was wondering if you can take a 2.2 eco head and put on the 2.4 eco block?
what kinda hp's are we looking at?
What would compression be like?
driveable?
easy or not?
possible or not?
anynone done it yet???????

Its probably easier than doing the Q4 head on the TC block. That's not a straightforward swap, btw. Nor is the 2.6 hybrid with the 2.4 crank in the 2.3 block. It requires crank machining.

At any rate, you'd see a loss going to the 2.2 head. the 2.4 head contains VVT goodies that the 2.2 head does not. The only reason the 2.3 head thing works is that the 2.3 head carries much bigger cams and has bigger ports.

Not so in the case of the 2.2 vs 2.4 Ecotecs.

understood what you mean

Hopefully it can be done


My ecotec "hybrid" L61/LE5 (aka 2.2L head and 2.4L bottom end) has been running since early this summer.

I dont look at it as a "loss" of power, since I considered adding the .2L of displacement to the 2.2 lol. But Megasquirt, and a few bolt-ons bring it back up to power. Getting rid of the LE5 head and VVT allow much more upgrades to the valvetrain also.

can you give more info pics vids? how does it run?

Just a few days ago I got it going good, I had issues with AFR and the coils. From the outside it looks JUST like a L61. I had to convert to the L61 coolant tubing, that runs around the tranny and exhaust side of the engine because it was in the way of the adapter plate and I also removed the oil cooler because of the lack of room. I also had to change to the L61 oil pan as the LE5 pan I had was cut in the bottom.

It seems to run identical to the L61 I had in it last year, but I never got a chance to tune it because of the weather . I will be converting it over to E85 over the winter. I assume it should hit close to 200hp0 once I get it tuned correctly and a few other problems sorted out, and with cams and a some valvetrain work should be able to nail the 240-250 range.

you HAVE to show pics. What type of car do you have? So do you have aftermarket anything or is it just the
head swap? Do you know what kinda compression your looking at? could you boost on that head swap w/o changing compression?

Its a fiero lol. I have a tsudo 4-2-1 header, custom drivetrain using a Quad 2.3L fidanza flywheel, ceramic 9 5/8ths clutch, custom CIA style intake, LSJ injectors, and tuning. The LE5 pistons are relived for the valves, stock form it runs 10.4:1, using the L61 head it creates quench pads that I believe may bump the compression up a bit higher as well. You COULD boost it, as the L61 can be boosted up to the 280hp range at which point the rods become a issue, the LE5 rods are stronger so It should be able to go a bit higher than that.

I have pictures over on ecotecforum.com, look up "EcotecFiero"

So, you're saying that a Quad 4 flywheel will bolt to the ecotec, no mods required?

No it needs quiet a bit of modification done to the flywheel to work.

If you cannot do the machining yourself, it would be much easier to do the ecotec transmission to it.

so why would you use the Q4 tranny instead of the eco tranny?

sorry coun't see your pics got a myspace?

Myspace is /Fosgatecavy98, I dont have much on their tho I'll post a few here.


I used the MT2 Isuzi 5spd. 1. I got a auto ecotec tranny with my motor, 2. the gearing is slightly higher than the ecotec trans. This + a higher RPM band allows me to run 1st gear to about 45mph, 2nd to 70, 3rd 95mph, the stock ecotec wants you to shift around 85 in 3rd.
