Corsa 140 or Turbo
Posted by: Revlane ()
Date: January 04, 2019 12:21PM

So after spending month's looking for a corsa I may have found 2 options that sort of match what I'm looking for.

One is in great condition but is a 180 turbo the other one is a project that someone left unfinished. both would need work in different areas to get them to be what I want but I'm not sure if the turbo is worth pursuing.

From my research the 180 turbo models are not that powerful and suffer from lag but I wanted to run this by the forum to see if anyone has had any experience or opinions.

Alos if you have any corsas that you are imnterested in selling please let me know.

The turbos seem to fetch a higher value/price tag.

The Turbo's can be a bit cold natured and sometimes finicky but when they are running correctly, they are great.
The 140's can also be a bit finicky when it comes to synchronizing the carburetors but run well when properly tuned.
Unfortunately the 140 is more likely to drop valve seats than any of the other engines unless they have had replacement "Deep" valve seats installed.

I am sure others will chime in with their two cents worth as well.
In the end, you are the one who will live with the choice you make.

IF you want dependable and enjoyable, my suggestion would be to find a Corvair with a 95HP or 110HP engine in it.
IF you really like the Corsa dash, you can often find a car that already has one or install one yourself.
It is also possible to find a Corsa that has a non stock 95HP or 110HP engine in it too.

I don't mind replacing valve seats or tuning carburetors, the ladder is actually kinda fun.

I don't have much knowledge of what it takes to maintain a corsa turbo specifically, but willing to learn.

If you had to classify the driving experience, which one would be faster and/or more agile?

Thanks

Show car,make it a turbo.A car to drive everyday,make it a 140.I'll put up with the carb sync problems and the valve seats dropping.Turbos drop seats too.

If you are looking to maybe autocross or something like that, the 95HP motor with a 3:55-1 positraction differential, heavy duty suspension, and fast steering is a good combination.
It would be a good set up for spirited driving on twisty winding roads.
You can have the same experience with virtually any of the 95, 110, 140, 150, or 180 engines when running correctly but that's just one person's opinion.

The basic ones also seem to be the most reliable and have less problems.
I love driving my 69 Monza Coupe 110HP 3 speed.

Thanks, I'm leaning towards the 140 as well.

Curious through, do you think it make sense to pursue a corsa, or would a Monza cupe be ok, with a 110hp manual

You won't enjoy replacing valve seats after they exit and impregnate every part of your engine. On the other hand, a properly tuned 140 will dust a 180 from 0 to 60 every time.

It really depends on what you are looking for. A 140 will give you better drivability off of idle and pretty good power through out the power range. Only downside in my opinion is keeping the 4 carbs in sync with the stock throttle linkage. Thank linkage can be replaced by an excellent aftermarket one.

A stock 180 turbo is a little weak on low end power but when the boost comes on, well it’s altogether another story. The YH Carter carb. is finicky

My first Corvair was and still is a 180 turbo. I was told from day one that I had made a huge mistake it getting a turbo. Poor drivability,turbos don’t last, the 140 is quicker and of coarse faster, la,la,la. So I built the engine with all of this in mind. Otto cam E/B flow turbo, 45 Weber with progressive mod,ceramic exhaust and a few more tricks. Off idle drivability is equal or better then any of the 140’s in our club and they are all fresh rebuilds with cams.From 25 MPH I can pull a hill in third gear.once the 140 guys have gone for a ride in my turbotheir ball busting stops immediately lol. Walk softly and carry a big stick!

It just really comes down to what you plan to do with the car. Leave it stock yet drive it often, the 140 might be the better route. Investment, turbos are worth more. Piss off the 140 guys, oh yea, a turbo is in your future! Lol

Thats actually great advice, just curious does the turbo makes any whine noises and is there a blow off valve.

Apologies if these are ignorant questions, I'm not well versed with carburetor turbo's.

On mine I did install a waste gate. I can hear the turbo at times, I have rather load muffler at full throttle.

With good carbs and solid linkage a 140 is not really hard to tune up. I am running a 140 with OTTO OT-20 cam, 3.27 rear end. Very drivable that gets 24 mpg on highway. If you are building a 140 go with deep seats or a very solid staking of the valve seats. As I stated earlier you cannot believe how far a valve seat can go if it lets loose on 140 heads. The smaller valves on 110's and turbos will trap it one combustion chamber. (For a while)

I have owned several Corvairs over the years and driven just about every stock drivetrain combination out there but it has been almost twenty years since I have actually driven any Corvair. The last one I drove was my V8 car back in 1999.

My current Corvair hasn't seen the road in close to 35 years but I finally began working on it this past June right about the time we started getting rain on a regular basis. The car sits outside these days as the garage only fits two vehicles so not much got done over this past summer.
The car is a 1965 Monza Coupe with a 110 block, 95 heads, it has TRW Forged pistons. It is balanced, blueprinted, the heads have been CC'd and hasn't been started in twenty years. The transaxle is a 1965 355 positraction unit with a 4 speed. I have replaced ALL of the rubber components in the suspension and have invested close to 15K in parts for it.
My goal is to get it together and on the road sometime this coming year and make it a reliable driver.
At my age (Early sixties) I would actually prefer an automatic transmission but will stick with what I have.
As you can tell by the attached photo's, I still have a long way to go.

500's Monza's Corsas are mechanically the same!

Interiors and Trim / are all that is different...


the 180 hp was offered in the CORSA only...

I have a '66 Monza with a 180 turbo... no difference in driving...


But since you say "Classic"...forget the Turbo's.... things that make a difference are visible...

Don't buy a project if you have the money to buy something complete!!! I've spent 3 times what I could sell mine for and that was with getting hundreds of hours of free labor. Corvairs still don't fetch much money and there are enough of them out there where people did a labor of love and will lose their shirts when the car sells.
