Question:
I Have a 1963 Austin Healey Sprite MKII, A series 1098cc Engine and need to get it rebuild, Is this something you can help me with?
Answer:
We don't actually rebuild 1098cc engines - only 1275cc engines. However, we can rebuild the ribcase gearbox. The rebuilt gearboxes are found here: https://www.minimania.com/part/RJM1109E/Transmission-Rebuilt-1275-Ribcase--Sprite--Midget

Question:
I am interested in purchasing a rebuilt 1275+ engine from you. Do you offer the 1275 just as a short block? I'm using a Datsun transmission with the thicker backing plate. Can you ship without your backing plate? Is the engine balanced? Will this engine need to be broken in or are the rings and cam already set when you started it and checked for leaks?
Answer:
All engines are built and run on a test stand and checked for leaks. So, the timing is done and the rings are run-in for at least the amount of time the engine is on the stand. The engine can be shipped without the backplate. Engines aren't generally balanced with the entire rotating assembly but it can be done.

Give our office and we can give you all the particulars.

Question:
Hello, I'm looking for a complete engine or a cranked engine for a 1275cc sprite (austin healey mk4 from 1968). Have you got some ? What is its price with a shipment to France? What is the lead time of supply. Thank you.
Answer:
Hi,
Currently we do not have any cores for sale.
thanks for asking.
 
 
 
 
Question:
Can I order without the carb, exhaust header, and spin-on oil filter stuff? I have my own. Would like the better 1.5 to 1 roller rockers. What would it cost?
Answer:
Hi,
We can customize any motor for you, just give us a call and I can work up a bid.

Question:
Hi, I have a 1966 Sprite with a very tired 1098. Last year after 2nd gear failed I purchased a rebuilt ribcase transmission from you. I am finally getting time to reassemble and I have decided it would be a mistake to not rebuild or replace the engine. New engine parts on the car that I plan on using with the new engine: Webber downdraft ManiFlow LCB header and full exhaust Distributor with Pertonix Alternator in a generator case The questions that I are: 1. I notice the 1275 High Performance includes a back plate, if I purchased one of the other engines how much would a back plate cost? 2. Do you have jetting recommendations for the Webber downdraft with each of these motors? Thank
Answer:
Hi,
We can certainly build an engine for you with the upgrades you listed.  I can get a quote if you need one.
We do offer used back plates  U-AEG552  .
Give me a call and we can go into details.
thanks,
Mini Mania Tech Support
