i recently posted about the new rx7 im planning to buy an the guy has proposed that he will either put a short block or long block engine in the car. now i dont know to much about these engines yet but im wondering if anyone can help me out cuz i wanna know the difference between them

With some variation, Short block is the "block" only. No intake system (manifolds etc), no turbos, no sequential control systems parts, no fuel system..rails, injectors lines etc, no ingition parts, coils, ignition harness, wires etc, no cooling parts, waterpump housings, water pump, t-stat ect., and no accessories...PS, AC. It's JUST the internal parts of the engine, along with irons and housings.

A long block typically includes all of the above mentioned external pieces with the possible exception of the accessories.

i see, so by internals your saying it has like the rotors the crank an everything inside the engine just nothing else.

an then i pose another question. im buying a roller for 5k, (obo so hopefully less) if the guy throws in a short block, how much extra would be an acceptable asking price?

In a rotary it's not called a crank, but an eccentric shaft. But you're correct.
I have no idea. And no one else will either without BEING THERE and looking at the car. As for extra for the short block, you're buying the proverbial "pig in a poke". No way to know what kind of shape the block is in. It could be a fresh professional rebuild with new everything and cranking out 100+ psi in compression....or a pile of iron and aluminum needing an immediate rebuild. Or worse yet, a worn out pile of aluminum and iron that isn't even rebuildable.
I suggested to you in the other thread that until you know more about cars and particularly rotarys you were getting in over your head. I still feel that way.

Sgtblue is giving you very wise advice. Once you've been on the forums for several years, we see potential new owners such as yourself in a similar situation 10-20 times a year.

I'd say 80% of them ignore the advice given by experienced owners and within a matter of months their car "sucks" and they are parting it out or selling it cheap.

Buying a FD roller I'd strongly suggest you have 5k-10k to put into it...a roller typically ends up being the most expensive way to get an FD experience has shown.

If you have 5k, I'd save up another 3k-5k and get a well document, running FD with good compression.

Regardless, I hope you choose to listen to members such as Sgtblue...I suspect you are jumping into more than you anticipate. Good luck!

i do understand that im in over my head, but currently is about the only time im gonna get to do this so i must admit im just kinda diving in, an thank you for your advice it has been very helpful thru this whole buying process. i guess i need to know where to start then. like where do i begin learning about rotary engines or these specific ones atleast. i know that experience is the best teaching in this industry but where i live there is maybe 2 rx7's within a 50 mile radius an maybe a hand full of rx8's. i just dont know where to start beside jumping into it like this.

Hi Zack-

Thank you for understanding I was not (and am not) trying to bash you. I didn't get into cars until I was in my early 30's and fell in love with RX7's and eventually the FD in particular (although I miss my first gen!).

I believe you will find that there are quite a few owners on the forum who have had their car from the beginning (20yrs...wow!) and many who have had their cars for 5-10yrs. The vast majority, if not all of us, want to see new owners have a great experience with these cars and understand the blood, sweat, frustration and ultimately joy that comes from having one of these unique machines.

That being the case, you are correct in that you need to "jump" in. There are very few reputable shops and in a case like yours...you are REALLY far from help. I'm sure you have already but make sure to read the FAQs and New Owner info in the 3rd Gen Section. I'd suggestion trying hard to use the search function for your questions as you may get a ******** reply if you ask, "How do I do the sleepy eye conversion?" which has been covered a million times!

I'd also advise to make sure you download all of the FSM's and Body Part Fiche's. Learn who Ray Crowe at Malloy Mazda is and take your time (but don't be afraid to ask questions if you really can't find an answer).

Good luck!

Let's be blunt. I doubt you've even changed oil on a car, let alone know how to fully assemble and install an FD engine and maintain the car.
If you don't know how to swim, you don't "jump in" the deep end of a pool. Likewise, you don't "jump in" with an FD.

ZackyVengeance

thanks gringo grande for the support its quite a change an very helpful. an where would i download those kind of things? are the like diagrams of the car? an i will look him up. thanks for the support an encouragement

sgtblue - no your right i havent changed the oil in the car. i havent sat in one. but i know a beautiful machine when i see one. an maybe jumping in isnt necessarily the right way to do it. but what else would you suggest? the nearest place for me to buy an talk to people about this car is 300 miles away from me. im basically alone in this town on liking mazdas. here honda is supreme. an i want to change that by learning about this car an bringing it to my town so that maybe i can bring that motors automotive culture to this area. but unless i jump in with this i dont know what else to do. so please if you have ideas for me tell me. im all ears an open to all suggestions besides what im doing is just wrong. please. i can here so experts like you can help me. help me

I know how you feel. I've always wanted to play classical piano, but everyone around here just wants to play the guitar. Oh well, I think I'll just spend/borrow $15,000, buy the biggest, coolest grand piano I can find and teach myself. Of course first I'll have to have a room to put the piano in. Then I'll have to learn how to read music. But that's not important. The only thing that's important is my wanting to be a classical pianist. And to be different than all my guitar playing friends. And since there's no classical piano music teachers that live within 1000 miles, if I run into trouble I'll just watch alot of PBS.

No sir... I'm not going to hold your internet hand and answer every little question you're going to have. And I doubt anyone else will either. Once outside the NEW MEMBER Section, you'll also find alot less tact and patience.

ZackyVengeance

then ill stay here in the new member section until i can get a good basis for what im doing. an if that doesnt work out for me then yes ill spend 15000 to teach myself an get frustrated an pissed off. cuz atleast then i will have taught myself something instead of just sitting here doing absolutely nothing about it. an if you dont want to help me then dont. ill find someone on here who will. but it makes me wonder why it is that you even bother with the new members section if you have no want to help them. cuz yes i thank you for your knowledge on the long an short block thing. now i know and wont make the mistake again. but if your so against helping me further then why did you answer such a mediocre question in the first place?
