2zz or turbo?

[michaelb]

Hi folks, I have been back and forth as to which route to go! I've watched some interesting videos on utube and still can't decide! The turbo seems to deliver power gains right through the range and the 2zz at the top of the range. However, the 2zz would likely be more reliable if I was to thrash the life out of the car. They seem to be around the same price, unless you decide to go big on the turbo. Any thoughts? I'm not going to be installing myself so those costs would have to come into it too.

Plenty said on this already.
They're so different you need to drive one to see what you like.
Remeber not all 2zz swaps make the power you would expect.

[michaelb]

I was reckoning a 2zz would deliver around 190hp, and perhaps a bit more with some other mods. A turbo should produce quite a bit more though and the turbo's are pretty small so lag/spool shouldn't really be much of an issue. It's a big decision and it isn't cheap, so I need to make the right one! Lol

Personally. After just doing a turbo conversion. The work is soooo much easier than an engine lift. That's including fitting a fake moroso sump etc. mines currently running 5psi actuator pressure on a gt2554, road tuned by myself (badly) and I reckon it's not too far off giving a 2zz a run for its money.
Although maybe not mikeks lol.

Definitely not a decision to rush into. I agree that test drives/rides would be the next best step.
They are going to be very different driving experiences so you need to know what you are looking for.

If I was looking for more power I would be seeing what comes up secondhand and looking at everything available.You have just missed a turbo coming up for sale.

[mikek]

As said above. You need to drive/ get a ride in both as they are very different.

@dan944 I think after Saturday I will be doing very well to stay anywhere near you!!!! Although I'm hoping after my visit I might be a little bit closer!

I'm getting worried about Saturday but your right. Until you supercharge that is
It's all about what you want to achieve. And remember to look into the future. If you can see your self having a power trip then sticking NA may not be best. If a little boost and great reliability is what ya want...scream away!!!

[michaelb]

I saw the turbo stuff for sale but wasn't in a position too buy it at the time, plus I remain a bit undecided. Dan keeps saying how easy it was to install a turbo but it's all the sourcing of parts that would do my head in! I'd want them all at once so I could begin! The only full turbo kits that I see for sale are in the states which I'm sure aren't cheap shipping over here. The local tuning shop thought a Subaru Impreza turbo might work nicely but I'm unsure. I don't want to be without the car for months on end either, especially with summer coming up!

[dan944]

If you use the list I've knocked up you can purchase the parts virtually in a oner. The only thing I imported was the manifold and it was the second most expensive item. But it is sexy. And took 5 day's :0.
But I'd recommend driving them first.

[dan944]

And don't buy a kit!!! Lol. Soooo not worth it.

They make 189 box fresh from Toyota.
A secondhand engine with 100k on it will loose some.
Then there is intake and exhaust which is crucial to get right.
We have had a few members who have felt completely underwhelmed by 2zz swaps.
MikeK's is definitely running well and I would suggest following in his footsteps to get the best from a 2zz.

V6 is the best anyway.

[michaelb]

I see there is a company in Rugby that sells the whole 2zz conversion for around £2500, then it needs fitting. I think I'd be happy to spend about £3k on fitting a good turbo though. I get what you mean about trying them first but there aren't any here in NI lol I'm a lone warrior over here!

[dan944]

Ahhh. Of course you are.

How power hungry are?/anticipated to be?

[michaelb]

Dan I think I'm about the only NI member! You actually see very very few Mr2s here. I think I'd like to go around 250bhp, not that power hungry....yet lol I suppose after a while you'd get used to it and want more!

If 250 is your starting point and you're likely to want more than it might be an idea to start with a 2ZZ and either turbo or Rotrex it...

I must be using the search function wrongly or something, I can't find Dan's Turbo Build! I had considered tubroing a 2zz but then my brain said "how much?" Lol

[michaelb]

Can you put any other engines into a 2? Like a 3L Alfa V6 or something?

[s12vea]

You need to drive both they are completely different beasts.

Apparently Audi v8 is t that hard

[michaelb]

Cheers Dan! Audi V8 it is then lol I would like to try them guys, but just don't have the capacity to do it! From watching stuff on utube the Turbo seems to be the more fun though and more powerful!

V8s
4.2 Audi

V6's
2GR
1MZ

V4's

Let's not forget Megillian's 1.8 VAG turbo conversion. He's about 80% there.

Talk about tuneability. 300hp+ easy peasy

[1979scotte]

What other cars have you driven or what car convoy want your 2 to be like.
With a 2zz it is going to be S2000 like.
With a V6 more like a Boxster.
Not sure what it would be like with a 250bhp turbo but bloody quick remember these cars can weigh as little as 950kg with that sort of power you are looking at Boxster GTS territory.

Anything over 200bhp and these things fly.
You should have come to ding day. 2zz/turbo/V6 all there plus an Elise a Cayman S and a Z4 to benchmark them against.

I've had a shed load of cars over the years from Jaguar XK8 to STI impezas, I'm just looking for something with a bit of punch to get the juices flowing! Lol I had to ditch all my 'enjoyable' cars when the kids arrived and so my weekend mr2 is my little bit of pleasure! I would have loved to have gone to Ding Day but I'm a 24/7 dad and it's hard to get any time. That's kind of why I was looking at just buying a turbo kit and getting the local tuning garage to fit it as I just don't have the hours in the day to shop and try and install.
