Rebuild....How hard?

[Mikey22]

Simple really guys.......how hard is it to perform an engine rebuild on a twin turbo RX7?

I don\'t know, but I know you can get a DVD with a step by step guide, might be one on eBay too? Someone will know more than me!!

Engine consists of a few plates, pair of rotors, 2 housings and lots of long bolts with some seals, the main issue with rebuilds is working out which bits you can reuse or not

[Lacey]

Rebuilds with a bit of knowledge aren\'t hard to do, as has been said there are instructional DVD\'s etc, and looking at a fully dismantled engine there really aren\'t that many parts to it, but as Mitch said it\'s the knowledge and experience, and eye to spot which things can be re-used and which things are toast - mostly it\'s just very time consuming

[Brett]

Depends on your experience TBH - there\'s nothing overly hard in the actual build per-se, just some fiddly parts etc.

Seeing how many seem to break within 10,000 miles of being rebuilt I\'d suggest it must be harder than it looks !

[Lacey]

Depends where you took it

i have rebuilt impreza sti engines and rotor engines in the past, and the rotor in my eyes was much easier, but that prob because i didnt use any old parts.

altho the tips were the most nerve racking part lol

Which ones are those? mine on 89k with compressions of 7.2 on the front, 6.9s on the rear, they only fail if you don\'t look after them, also less moving parts to go wrong!

I\'m just about to rebuild my fd engine never tried it before, but armed with the dvds, a full rebuild kit from atkins my housings and rotors look ok but ill be taking them to someone that knows to make sure they\'re not screwed machine shop to make sure they\'re totally flat and get them ported

My thread is over on driftworks, ill post up a million pics and vids of it

yer def keep us posted dude

I would say it depends on why you need to do a rebuild?
If it\'s a apex seal gone...it\'s going to have damaged the housing possibly iron plates and even a turbo or 2, if it\'s a water seal gone... Then perhaps easy... But depends on if it went due to a simple over heat , time... Or dreaded water seal Chanel corrosion which means new housing and plates possibly!
Now if it\'s just low compression but running all hunky dory then yes should be an easy rebuild with many parts able to be reused!
However the majority of people wait till it\'s broke broke which by then the damage is done!

Yes I am a newbie but done a fair bit of reading on all this due to my pending engine rebuild mayhem myself...

Mines had a coolant seail failure, all the apex seals were in good order and both housings seemed to be too. although they have marks on the inside, there is nothing you can feel with a finger (scoring etc) Both rotors in good order, and the area where the coolant seal has failed hasnt corroded through
 
Ive taken it all apart and labelled it all, the engine parts are going to an engine shop to ensure they area ll 100% flat surfaces and to be chemically cleaned.
 
Just bought the atkins rebuild kit (should be here soon ) My turbo\'s are in good order, though I do keep looking at a single longingly lol (not sure why)
 
Im aiming for a budget home made rebuild without skipping any steps to hopefully build an engine that will last 15k+ miles experience though is everything

[merlin2002]

Also the housings and the plates all have a nitrate hardening process which can not be done by any machine shop!  They cannot be milled down till they are flat! As they will score and damage which will lead to lots of lots of blue smoke and another expensive engine rebuild!

If anyone wants to correct any of my points raised here, please feel free
