 |
|
Hi,
I have a rare Japanese 75 toyota import and currently running twin aisan SU carbs which repair kits are finding impossible to find, i have been offered the choice of installing some new SU carbs, but this has been estimated at 3.5-5k (im guessing for the conversion?), does this sound correct to everyone? Its just a lot of money to put into something im currently trying to sell, and i dont know what to do as im going to be loosing more than a few grand if i flog as a project

Don't buy them.
You don't say which SU carbs you need. NO WAY should they cost that much. You could buy a supercharger for that!

Ray is right.
Someone is trying to scam you!
If you're planning to sell the car anyway, then you'll almost certainly be better off just selling it now. Sell it as it is, for what it will fetch, even if that's a fraction of what some "expert" thinks it ought to be worth, even if it's only scrap value. There's no surer way of losing money than spending it on "fixing up" an old car with the sole intention of selling it on. |

I think we are both probably speaking from bitter experience!
There is a saying in the restoration business that you make your money (if you ever do) when you buy a car - not when you sell it! |

What model Toyota/Aisan carbs? Have you tried the owners club? Ebay USA, or New Zealand?

Well, I never poured money into a car and lost it like that; but it's been my experience that whenever I try to sell something - anything really, not just cars - it eventually goes for a heck of a lot less than it should have, that's if it sells at all and I don't end up giving it away, humping it to the tip or putting it on a bonfire. I've also seen cars advertised over and over again, sometimes for years, because the vendor wants what some book or magazine article thinks it ought to be worth... but the potential buyers don't agree or can't afford it. Anything is only worth as much as someone else is willing to pay, and with a lot of stuff finding that someone is a challenge in itself.
A very few people do manage to turn a profit on fixing thing up, but they're a particular type of unusually lucky (or crooked) person... if you have to ask how to do it, you're not one of them and you will only get burnt by trying. |

I am unsure what carbs they just said SU make a similar one, ive heard H6 a lot. Ive also just found out mine are aisan SU ISO carbs which are even rarer, im losing a lot of money as is, may just take the bullet now |

Toyota corona mark II 1975 18R engine so very rare with twin aisan su carbs (shes also a japanese import) - ive tried the owners club, the garage contacted toyota australia, im messaging aus and american carb companies but no luck this far
The main part theyre saying is the diaphragm being worn - shes basically idling but the revs drop then bounce back up. Im losing a couple thousand as is trying to sell at 8000 so i may just cut my loses and loose a lot more rather than cause more pain |

Hi
Is this car advertised, the car in question?
https://www.carandclassic.com/car/C1481724
Looks like it has twin SU carbs fitted....
For a 2 litre engine I would think a pair of SU HS6 carbs would be adequate?
Brand-spankers, you're looking at around £1000 for a pair from Burlen Fuel....who make the things.
The presence of a diaphragm suggests your carbs are similar to the Stromberg types?
These have a similar operation to the SU, but have a diaphragm instead of the basic rising piston.
If switching to SU carbs [cleaned up, 1 1/2 inch SU...HS6, off ebay?] then you'd need to measure up the manifold to carb flange sizes first. It may be possible to utilise the existing Toyota manifold?
Another option is to go to a single, twin choke side draught Weber[40 or 45 DCOE, perhaps?]
Both the SU carbs, and the Weber, are fully adjustable to suit the engine's needs...the Weber by changing the multitude of jets and emulsion tubes, etc...the SU by sorting out the needle tapers.
Another option is to embrace the concept of fitting bike carbs?
[Especially appropriate if the cylinder head is in fact a Yamaha product, as some were?]
These can be selected and tuned to give better efficiency from the engine.....it isn't necessary to equate the fitment of bike carbs, to outright horsepower, believe me!
The people to contact for this route are Bogg Brothers, in East Yorkshire.
https://www.boggbros.com/
Their pricing is not in the least outrageous, and they have their own rolling road for fine tuning. Tuning, incidentally, is their forte! None of this fancy-pants computerised stuff.....long thin screwdrivers and decades of practical knowledge have won out over high tech!
Bogg Brothers are also the people to contact if a new manifold is needed to be fabricated for whatever carb or fuelling route you take....

Hi yes it’s that car, gonna be selling it for a lot less now, would it really be 2k+ on top for labour? The garage I’ve taken it to is one in West Yorkshire who specialises in 70’s cars & can manufacture new parts so they’d be doing it all, just very confused by this all, my first carb car so trying to learn things too |

There are lots of pairs of refurbished HS6 carbs on eBay for around £500 (think Triumph Dolomite/Sprint) - even if they need adaptors and re-jetting for the Toyota I can't see the bill being as much as £1,000.
