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

Hi. I've called you a couple of times already, but I want to be sure I'm doing the right thing. I have a stock '58 Morris Minor 1000.I'm trying to figure whether to go with the 1380cc or the 1275 but will my existing gearbox fit either engine? I welcome any suggestions about how to make my car a bit more competitive on todays roads. I already have disc brakes and good suspension. I am used to SU carbs, never had Webers; can the specs be changed to take SUs if we go that route, the 1380HP?
Answer:
No, not really. The smoothcase gearbox isn't a good fit for the 1275's. It would be best to get a ribcase gearbox for any 1275, no matter how bored over. Hope that helps
Question:
I have a 1974 Midget. I want to give the 1275 a lot more power but I don't know where to start. I am not going to race it. It is just for fun. I own a '76 that is done but is nutless even with a Kent Cam, weber, header and Monza exhaust. I was thinking of adding a supercharger too so can you point me to products you have for a complete rebuild. I want to add a new cam, crank, rods, heads, valves, lifters, pistons, flywheel, the works. I don't know what parts would work best with each other or would be best with a supercharge or not. I want the engine reliable and cool running in the end. Your thoughts for the best engine for me?
Answer:
Thanks for asking, let me share a few thoughts.Your objective is pretty common. You should note that a stock '76 Midget cam with a 1500cc Triumph motor that only put out 56HP. We offer no parts for Triumphs and thus also no advise. As for for your 1275 my first suggestion is that I would NOT suggest a supercharger upgrade when you also wont a reliable and cool running car. Looking at your list of other potential upgrades (" I want to add a new cam, crank, rods, heads, valves, lifters, pistons, flywheel, the works") I would suggest a more cost effective proven direction would be for you to simply order one of these: https://www.spridgetmania.com/part/1380HP_INLINE/1380-Cc-hp-High-Performance--Sprite--Mg-Midget---Morris-Minor

Question:
I have a 1972 MG Midget and it needs a power upgrade.
Do you have the 1380 cc performance engines already in stock? Are they custom-built to order? If so, can I make changes to the listed setup? (ie. different color engine paint, different carb, etc.)
Answer:
We don't stock engines as they are all built to order. You can pretty much have one built as custom as you like. We can either have you send us your engine to rebuild or we'll use a core of our own. However, if wanting to go to a 1380, it's imperative that the core be standard (not already over-bored) since 1380's require offset boring and anything already .020" over or larger generally don't make good cores for this process.
It would be best to call our office to discuss your needs.

Question:
I'm looking for and Classic Mini HP engine and 5-speed transmission for a 1959 Austin Healey Bugeye. HP Engine the best thing that you have that will fit. I want power but I don't want it to look like it.
Answer:
The HP engines are our higher end engines we offer online - however, we can build just about anything on the A-series engines. Full custom builds are what we do. If you're looking to keep a stock "sleeper" look, then the HP is the way to go, you can always bore the engine out for more power, the 1380HP_INLINE is good for about 115 horsepower (and can go higher with some add-ons) Best to give us a call for details on custom engine builds.
