What's the difference between 1ZZ-FE and 1ZZ-FED

[MIKEP]

I am trying to get a new engine for my Spyder and I can get a low km late model Celica 1ZZ-FE at a good price.Whats the difference between a 1ZZ-FE and a 1ZZ-FED besides 8HP and the fact they are built in different factories.

Is there any other difference.Do they fit and connect up ok? Any advice appreciated.

I haven't seen anything official but it seems to be most the time there's a different cam setup unless it's old enough to have something to do with the carbies

HI Michael

Thanks for that but they are both late model and both Injected so im not sure that applies

Thanks anyway

Mike

Sorry I was referring to how Toyota uses the "D" in their engine designations, when I said old I meant older than our cars. I think the only difference between the 1ZZ-FE/D is in the cams hence the small power difference

The D in Toyotas engine coding system means Carby "Twin downdraft carburetors or Toyota engines used by Daihatsu without VVT-i (e.g., 1KR-DE)" But the new engine coding seems to go outside of this coding system.
Like you all I found was a mention of cams but only one and nothing on the proper engine specs. The other thing I found was the "fracture-split forged powder metal connecting rods" for the 1ZZ-FE and the FED having lightweight cast rods.
The camshaft part numbers do change in October 2002 but only the last number 1 by 1 digit usually meaning the product could be moved to another place rather than big change to the part but the pricing on them is quite different. Not sure if this an FE vs FED difference though.

Like I said, nothing official. I wouldn't trust Wikipedia for fringe cases about engines, it is wrong often enough about Japanese cars and can be very wrong about them sold in the NZDM. As you know, it's much better to use OEM EPCs but they can be incomplete and shouldn't be used to say anything other than something exists.

Hahaha....AHAHAHAHAHAHAHAHAA!!

just put a 2ZZ in it - save yourself the disappointment that is a 1ZZ

(seriously, just do it.)

All 1ZZ motors are just as shit as the rest - there is no noticeable performance difference.

[GDII]

Yeah. It's hard to find data on NZDM and JDM cars as most information on the net is from America. Many people get confused about the difference in the SW20.

I used the EPC to find part numbers on cams but all it gives are numbers and never any specs.

He's going to slap you for suggesting it but I'm with you. The 1ZZ was an economy engine and should have never been put in the MR-S. I'll take a slap for that but I stand by what I say.

[EssDub]

I get 'slapped' a lot.

I then end up converting cars.

Can't argue with cold, hard facts and tangible evidence, eh?

I like Mr Green.

[MIKEP]

Thanks and Slapped (Some people might think you get slapped so much cos you don't listen) LOL

The 2 ZZ swap is bloody expensive The motors are expensive here and a lot rarer than 1zz and all the ancillary bits you need to change. engine mounts , ECU,Headers , Throttle body, wiring loom adaptor, air intake etc It isn't just a straight "bolt in plug and play proposition"

For the money and the amount I use the car its not worth it.Performance isn't an issue .

Also as I have Arthritis in my wrists and I have hands like tits I wont be doing the job so I will have to pay someone. Everyone will do a like for like swap but no one is willing to take on a "nearly the same but a little bit different " job on a fixed price and im not about to write an open cheque.

Anyway all I wanted was info on the difference as I thought I had a reasonable solution.

[EssDub]

They wont be any more expensive than a rebuilt 1ZZ...

Just to clarify:

engine mount (redrill the 1ZZ mount)
ECU (comes with a motor kit)
Headers (mod Celica header to fit MR2 exhaust)
Throttle body (Part of le engine)
wiring loom adaptor (wut... 6 wires to change, 3 to add, job done)
air intake (use stock)
It isn't just a straight "bolt in plug and play proposition" (Might as well be, given how similar they are)



One day, you might get the chance to slap me IRL... but please, not with arthritic boobies... that couldn't possibly be a nice thing

[MIKEP]

I still don't know the difference between conventional 1zz-fe and 1ZZ-FED.

I am not putting a 2ZZ in so all platitudes aside thanks anyway. They are rare and expensive here and cars with 2ZZ in go for the same price as 1 ZZ when sold .

And what you end up with is what you got. An MR2 with a celica engine in ....>

[EssDub]

Different rods.

Thats it.

There were revisions to the pistons in late 2002, but that was simply a modification to the original (shit) design.

[MIKEP]

cool thanks

I got t a1ZZ for $250.00 so im good to go.

Thanks . Must be some villages somewhere that have lost their idiots.......................................Some of the guys at wrecking yards and engine importers are just plain thick

[MIKEP]

Didn't realise how stuffed my engine was till I got my car back today to test . 2008 1zz fe with 68 k on it new water pump,crank seal both ends,rad clean,gutted cats,new thermostat .

Put an Exedy performance clutch in. Different car.I am impressed.

Watch out next run!!
