Hi I'm looking at buying an 91 Uzz31 supercharged soarer. I flipped my standard Uzz31 and I'm looking to rebuild but it will take years.
So the new one was raced in Targa Tasmania 7 years ago. Last 5 years an 70 year old man has used it as his Sunday drive, services it every 5,000km, lives in the shed.
It has a adaptronic piggy back computer which I'm told needs a retune. The car ideals very high, he said it would rev to 3000 and then cut out when starting so they put a fuel regulator to fix it. Every now and then it throws the ENGINE ELECTRICAL FAULT up on the dash. Guy tells me its the new computer over writing the old but I'm not sure as it does it when put under a lot of load.
Also it doesn't kick back a gear automatically and it feels very slow like it has no bottom end grunt like my old one. I don't know the first thing about superchargers so if you have any useful information please help me understand as I don't want to buy something if its already has big issues.

It could be a faulty factory ECU causing some of the issues, may have issues with Fuel Pump ECU also as it's a common thing - but these are all guesses as it could be other things.
Sometimes if piggy back ECU's aren't tuned right they can cause conflict with the original ECU as they both run at the same time
You don't want to buy a Lemon, so you could ask how much they would sell it for if they got the issues fixed? May save you a headache.

I'm doing a lot of research into it! they have full history of the car including when they got parts, fitted, fixed and costs. I'm trying to get in contact with a local company which are the best for tunes. Also looking at maybe getting a new computer

I am running EManage Ultimate with my supercharger works very very very well... I didn't need a fuel reg at all to run 10PSI, just a Walbro fuel pump. What injectors are currently in? You can check by color of the cap, what you are describing is how my car ran when I dropped in 7mge injectors and tried to mess with a tune my self, check vacuum leaks, Idle control valve. Main difference I can see between my set up and what that car has, is I got rid of MAF, maybe try the same, just unplug it? maybe its just dirty, electrical fault you are seeing is probably caused by it.

Sounds like it's got a lot of issues that most likely are not related to each other - transmission could be a solenoid for example or may be related to ECU issues. Plus if it's been in a targa it's had the balls thrashed out of it.
I'd steer clear unless part of the deal was for the current owner to get the problems fixed, or at least find out what the causes are before any money changes hands, or you were getting it really, really cheap - otherwise you'll be inheriting a project of unknown size.

Hi Jessica,
Do you think that the fact it was supposedly raced in Targa Tassie is having a positive influence on your decision to buy it ?? or were you just mentioning it ??
As i cant see much from your photo but it appears to be quite standard apart from the super charger in regards to other Mods like the seats, shocks etc etc, if it doesn't appear to have had a harness and roll cage Now or in the past amongst a lot of other upgrades including Big Brakes fitted to it I would take it as a grain of salt that it was actually raced in the targa, if It ever did so called compete I believe they have like a Non competitive touring type entry level that they are not allowed to exceed certain speeds & I think are almost driving at the road legal speed & so don't require the safety stuff the big boys have & so can be basically a standard road car driving around Tassie following the same course but quite some time later after the big boys, which in my eyes accounts for zippo as far as the owner saying its been raced in targa tassie ..
As you said it appears to have some issues, do you mind me asking roughly what sort of money they want for it, as that would be the big deciding factor if I was in your shoes ..

Rob your right with the tour stage, it was entered by Stevo(driver) and Naz(navigator) for a few years who are both paraplegic and a couple the funniest and most inspiring people I have ever met, I still see and have contact with Stevo, he has moved on from the soarer a few years ago into a saleen mustang The car has been very well looked after. I am aware of the intermittent cutout/miss but would think with all the knowledge here that it could be fixed.

Could it be possible spark issue? I had a faulty coil that gave similar problems. Not sure about the high idle tho unless they've done that with the adaptronic.

cleaning up someone elses electrical gremlins is a costly and frustrating exercise, even more so if you have to pay someone else to do it, how much are you willing to spend to get this thing running right?

i think maybe the idle air unit is ceased for it to rev high but these engines can handle big rpm so if •• using it as a daily driver i recomend putting a reuild kit aprrox $150 to $200 on the supercharger because the bearings would need to be replaced and the oil. That prince includes parts and labour maxiumum
also ull find u will have to retune •• engine piggyback which isnt a big issue with that set up you have piggybacks are great for slighly modified cars ut if u up the boots to mor ethen 10 psi onwards id recomend a standalone which is anywere from 1500 to 2500 including tunning but you will gain fuel efficancy and more horspower gains

Failing to kick back could be a misaligned TPS. This car has been raced. Thrashed. It probably has high km's also - and many lil dings.
Don't go for it - simply due to the fact it has been raced. Sure, it has a charger, but what's that matter? It's a dead charger which has been thrashed, along with the engine and so on. Already the car has issues with not kicking back.
Low fluid, vac leak, misaligned tps, or bad maf can cause this.
To find out the cause, will take some hours - or some dollars.
I suggest finding a better/cleaner soarer - an old womans soarer from ebay or something - and then putting a supercharger on THAT.
If this car you are looking at is $4000 or so, go for it. Charger costs like $5000 fitted anyway.
If the car is $10,000 - ignore it.
But a nice low km soarer - hell, even import one from japan for 4k in total. (1k for car + shipping and compliance).
You can get superchargers fitted on any soarer - for around 4-6k. So, yeah...
I'd steer clear of THIS Soarer you are looking at, But if you can diagnose the TPS/MAF/Tranny and so on, and it turns out to be an easy fix - buy it.
