Rebuild a engine at home?

[interloper393]

Hi guys just after some advice here, i love the rex but hate the 4k rebuilds, was wondering where the best places to buy the rebuild kits are and whats best to replace when rebuilding a engine? id rather replace the housings just for piece of mind..
Iv got the dvds coming soon for the rebuild and i also have a friend with a gen 1 rx7 that he`s rebuilta few times so i can grab a hand of him when im stuck lol..:Thumbs-up ..
Id love to give it a go as iv alot of space to do it and id love 2 know i did it

Any links to cheap parts and kits would be great..

cheers for the help..

p.s im importing the car from japan so will be low mileage, i know this dosnt mean a great deal :spank

I think the rotaryavation kits are good, there is another one out there or you can get your own parts. Not sure you\'d need to replace the housings, just get them checked by one of the specialists.

I\'m going to be rebuilding mine at home with a couple of friends later this year. Hoping to get some things like porting done and I\'ll see what I can replace in terms of piping and other bits once the engine is out....don\'t need it for driving day to day so no rush

Good luck anyways!

been looking at that kit but been reading abit about them and think theres somewhere in the uk the does them cheaper?

Really looking for the best kit that a few peaple have used and know its gunna be good lol.. think i`ll start with the basics then work up to porting and things.. would like to replace thepipes for better/newer ones so theres less chance of them spliting..

lol cant wait to get started

i\'m doing mine had all my parts checked over by a specialist and replaced a fair few parts.  just got to save up that last bit now for oils etc etc and some piping. There is a company in the states thats lists all the piping your require for the rats nest with the dimesnions and lengths so you could use that info and buy from somewhere in the UK.

but then i need four 19" tyres so there isnt a rush not exactly a lot i can do with a car that has no wheels

I\'m going to be talking to you a lot when I start Dean

interloper393 know what you mean....there are noises which i\'m sure i could fix and stuff but i can\'t wait to rip everything out and tidy it up and clean it all

[interloper393]

kewl dont suppose you have thelink for that site do you bud lol.. think there quite a few willing to attempt a home rebuild now that they know a fair bit about these engines.. think the most worrying part.. (for me anyways) is the engine removal.. but with the dvd`s i dont think you can go wrong as long as you take yer time.. im really itching to get started lol.

Dont suppose anyone can arrange a cheaper group buy for a master rebuild kit or the basics on what all rebuilds need?

i think hose techniques was the company name but this is what you need according to them

kit for all vac hoses contains:

40\' of 3.5mm for small solenoids
15\' of 4mm for washers and boost control
16\' of 6mm for larger airlines on engine
 4\' of 8mm for the big airlines on engine

hope that helps

[interloper393]

Seen a few topics and theres 60 all in ?? lol wow sOOOooOOooo many..!! would like to upgrade them to better pipes with metal clicks to stop them flying off at will lol..

On the side of the rebuild kits saw this on ebay.. not for the turbo tho, add another 300usd for that..

But i`ll still need rotor tips wont i? anything else in the kit that id be best to change? i know i`ll prob need housings and ill jus get a new pump for peace of mind.. also gunna upgrade the radiator and ast tank while im here..
What cha guys reckon?

I think general consensus is that it\'s best practise to go with genuine Mazda parts for the rebuild. Mazda have invested millions into developing these parts, whereas other do not have the resources to do this. The Mazda parts may be more expensive, but there\'s a reason for that: the quality, experience and research have gone into it.

[interloper393]

Can you tell what what bits n pieces you used to rebuild yours bud? specs n prices lol..

Good on you for rebuilding yourself. I rebuilt my first zed engine which is much more complicated than the rotary. I had no experience, just a lack of money to get it done properly at the time . I was amazed when it started on the key! (especially considering the box of bits that I didn\'t put back on!) It did die again 3mths later prob due to not replacing the shells ,but I still think it was worth it due to how much I learnt doing it.  If I have some spare money I\'d like to pick up a rex shell and build it up, the rotary engine makes so much sense.
I\'d deffo recommend it, don\'t be scared about pulling the engine and all that stuff. It just needs patience, and if that fails then a big iron bar!!

[interloper393]

Ooo i have a big iron bar i got it from kwikfit lol..

[interloper393]

Ok heres a list of what i reckon a full rebuild will need, is there anything iv missed out gasket/seal wise?

Main (internal) Gasket Set* 1  
Rotor O-ring Lg 4
Rotor O-ring Sm 4
Rear Main Oil Seal 1  
Front Main Oil Seal 1  
Corner Seal Plug 12  
Corner Seal 12    
Corner Seal Spring 12  
Side Seal 12    
Side Seal Spring 12  
Thrust Bearings  2  
Oil Pump Chain 1

Thermal Pellet Plug 1  
Apex Seals 1 set  
Apex Seal Springs 1 set  
Water pump to block gasket 1

Also would it be worth while upgraded to 3mm seals and would i need to make any otherchanges if i added them?
