1zz / 2zz difference below 6000 rpm

[105e]

I am not thinking about a 2zz transplant but just wondered if the 2 engines feel similar below say 6000 rpm

If you look at the dyno graph they pretty much are the same, 1zz gets a bit more low down torque due to the difference in bore and stroke

Yeah they feel very similar in my opinion having owned both at the same time. The 2zz felt more dramatic but that's only because it had a more fruity exhaust. But once you get to around 6000+ RPM in the 2zz it kicks you in the back. Fantastic on track and the right road. 1zz much more usable day to day though depending where you live (particularly if built up).

Day-to-day, the 1ZZ and 2ZZ engines feel quite similar. Its only when driven quickly the 2ZZ comes into its own.

I still believe this is something Toyota should have done from the factory. Had the MK3 MR2 had the option to come with the 2ZZ in a TRD/T-Sport version, I think it would have helped shake the hairdressers sports car image that the car had 25yrs ago, and carry more kudos beyond the MR2 enthusiast crowd and be remembered as a modern great small sports car.

That said, is it worth the cost of a transplant for road only use? IMO No.

I guess like anything, we'll agree to disagree.

I absolutely love my 2ZZ and would do it all over again - although there are a lot more choices now. I'd probably be tempted to go down the route of the Zurawski 1.8T VAG. But it's a lot more money.

It's fun as hell on a regular road and teamed with the JDM ECU, it's a hoot once it's in lift.

Never tracked it. Never will. Don't have the talent or the wish to ruin my car.

I love to hear them on song, but I know I don't want one.

Just doesn't fit my style of driving.

No right or wrong just a taste thing.

I just think the cost of a 2ZZ transplant these days - and let's be honest, finding a good donor 2ZZ is getting hard and it is starting to be serious cash - even a +150k mile engine, high risk, with no history, is selling for +£1k now. The 2ZZ, with its MMC, is not such an easy (or cheap) engine to spruce up.

That sort of cash that starts putting it in the realms of other options.

5-6 years ago you could DIY a 2ZZ swap for <£2k - the MR2 became a lot of car for that money. Unfortunately those days are gone.

The advantage of the 2ZZ will always be it drops (almost) straight in and changes very little to the balance and feel of the car. Its one of the easiest and most natural engine swaps going (which is why I think Toyota should have did it from the factory).

I drove a car converted by rogue and in general driving there was no difference whatsoever. It was only when you got on a country lane or accelerating on a dual carriage etc when you held the revs that suddenly at 6k it's shifted when the 1zz was out of puff. Unless you're hammering lanes daily it's a really an occasional kick. Not really worth it IMO and I guess why they never offered it as a stock engine

[Alex Knight]

Lest we forget one thing: reliability.

The 2ZZ is miles ahead of the 1ZZ in terms of that. 2ZZ is orders of magnitude less likely than a 1ZZ to start consuming bottom ends.

My 130K mile engine burns absolutely zero oil in between changes, including heavy track work.

I don't recall ever having to top up my oil in the last 12 years.

Admittedly, mine was a couple of years back, but it was around £3k fully fitted. Engine was a mint 50k miler and JDM ECU. That included gearbox rebuild etc.
 
I'm intrigued on what else could be done for under £5k? The two options on the table appear to be the K20/24 which is in the region of £8k. And even then, I'd be questioning the provenance of the Honda engine.

I saw quoted £10k plus engine for a 2GR.

The alternative is the 1.8 BAM which gives you 225 out of the box, but is unlikely to cost you less than £6k.
