What to do?

Sorry for the long post but I need to set the scene. I have been building my Supra for the last three years, here is a link to my garage for photos and current spec.

 

http://www.mkivsupra.net/vbb/vbpicgallery.php?do=view&g=1991

 

The car made 591bhp at the fly at 1.75bar which was ok but I decided to get the head ported and polished to see what improvements this made. After this was completed the car was took to Mark Shead for mapping.

 

Unfortunately on the road run at 1.6 bar a water hose popped off and we feared the worse as the temp gauge maxed out. The car was stopped immediately to minimise any damage. After letting the car cool down, refilled the radiator the car was taken out and driven steadily to see how it drove. All indications were good, temps were back to normal at normal driving and there was no obvious signs from driving to make us think there was a problem.

 

After road mapping I continued to get a single power run on a Dyno Dynamics dyno. The car made 516bhp at the fly which was obviously 75bhp down on the last power run prior to porting and polishing of the head. I was obviously upset and seeked answers to why the power had dropped. It seems the brief overheating has caused some damage. A compression test confirmed this with the following readings

 

piston 1 150

piston 2 150

piston 3 150

piston 4 140

piston 5 131

piston 6 130

 

Actual diagnosis for the exact problem still needs to be confirmed but indications are that at best I need new piston rings, at worse, new pistons and rings. So is suppose anywhere between £2000 - £4000 to repair.

 

I have had enough of the car now and have decided to sell, my questions are the following

 

  1. Should I repair the car in full,mapping and power run and then sell?
  2. Should I sell the car as it is with a obvious price reduction?
  3. What would the car be worth in a fixed state?
  4. What would it be worth as it stands?

 

Dont really want to break and sell the parts as it will take to long. The car was built from an empty shell upwards and has an extensive build including full respray and currently owes me in the region of £40k:(

 

Please advise as I have lost faith!

 

Thanks

Get it repaired and sell it mate if you have had enough. You have a STUNNING car. With some very nice parts. It would take a long time and a lot of effort to brake.

I saw it outside halfords a few months back and still looked great.

 

If you wanted to brake it i'd take the tubby kit off you but i dont have the money :(

 

gutted for you :(

It will always be worth more being fully functional. It would make sense to fix it and then sell it if you so wish, the fact of the matter is, you won't see 40k, but you would see something realistic.

 

Hi Gav

 

Yeh i know it makes sense to fix it but what do you think a realistic price would be? f i could get £10k as it is and £14k as repaired, I could see the worth in fixing it especially if the damage isd not horrendous.

 

What do you think it would be worth in a fully functional state - I was hoping for £16k - realistic or not?

Hmmm, it could go offshore for more. Perhaps have a word with Jurgen, given the amount of work that has gone in, I would have thought it would possibly be worth more.

Wahtever happens, the car is definitely going!

 

It is a shame, as it is a lovely example...

 

If it were me, I get it checked out properly to diagnose which bits have gone, as it may not be as bad as you think, and I'd still maintain a working car like yours is worth SOO much more than a blown one.

The compression is not that bad, ive seen worse, how do you know its the rings and not a head issue?

 

Does the car smoke? was is dyno'd on the same dyno?

 

Being auto i think you will struggle to get good money for it.

 

Hi Jamie

 

No smoke, no overheating, some glazing on the bores so possibly rebore and new piston rings i hope. Until the engine is took apart, no way of really knowing.

 

I would hope £16k would be realistic a few grand for a manual conversion and a high spec manual supra would belong to the new owner.

I just dont think there are many people that would spend that sort of money (Gaz1's stunning single 6speed never made that much and was forsale for a long time) on a auto supra in this climate, i hope im wrong though and good luck with what ever you do.

 

On another note i thought this car made over 700bhp? maybe im getting mixed up with somebody else:)

 

Edit, no it was you.

Different dyno mate, 591 on dyno dynamics, i was expecting more hence why head was ported and polished. i was hoping the spec would of produced 600bhp at 1.5/1.6bar but not so laggy

Are you sure the head`s 100%? Valves seating ok?

If it IS pistons/rings wouldn`t a s/h engine work out cheaper?

 

Not sure mate but my engine had a lot done to it and I am hoping alot of it is still ok to use, not sure what the costs would eb to transfer together with buying a 2nd hand engine

Thanks for the advice guys, well i decided to get the engine repaired. On further investigation the damage was not as bad as first thought. The rings were knackered and there was glazing to the pistons caused by overheating due to the water pipe popping off. As we speak all issues are being sorted with new parts and I should have the car back by friday.

 

The car will be for sale shortly so if anyone is interested prior to the official add, please drop me a PM

 

Thanks again for the advice

All that hassle for 36-months and you want to sell your pride and joy.

 

I think your passion will reignite once you have her up and running again

 

Unless you need the money for other plans then I would certainly consider keeping the Supe.

My previous Supra was stock engine running a PHR Stage 1 - great car with no problems. This one has certaintly been a test. In all honesty I dont want to drive it as I know I will want to keep it. The missus wants to keep the Supe as she is insured on it and loves driving the car.

 

I have just decided to sell and buy a sensible nice family car, a shame i know but FAMILY first:)

No worries mate, I thought glazing of the bores and pistons was caused through light loads in the running in phase of an engine build where the rings/valves dont hone properly

 

On further reading I found that overheating can cause relaxed rings and glazing to the pistons causing low compression. Either way, a aggravation which has been costly to repair. I am surprised that a water pipe slipping off can cause so much damage - :)

 

I suppose it could have been worse, damage to the HG or head was possible but no damage was found luckily.
