Title: Already Put a Deposit on a FD
Post by: darknight7777777 on June 14, 2009, 09:37:22 PM
Hi,
i have put a 1995 Black Type R with 60k  on the clock. I already am expecting to do a rebuild or to refresh the engine but i wanted to ask you guys for a opinion. All i know is that is it has 6.0 bar on both the front and back rotors.
 
What do you guys think.
 
Rebuild or Refresh.
 
thanks in advance.

Rebuild and refresh are the same thing bud. But if you can afford to, I\'d say get it rebuilt, cost a hell of a lost less than when the engine has gone pop and give great peace of mind.

Ah ok sorry keep hearing both but never together. I guess I will start looking for some one to do for me. Can you give me a rough idea on cost. So I know I not getting ripped off.

Figures wise:

8.5 - 8.0 = Fresh engine

8.0 - 7.0 = very good engine

7.0 - 6.0 = ok at the mo but will require rebuild soonish

6.0 - 5.0 = critical not very long before failure.

You can\'t get a simple answer than this. I wish someone would stickie just this part for future buyers.
 
I have the Rebuild dvd\'s from rotary art so i am gonna get my uncle to do the rebuild but he hasn\'t done a rotary before do you guys have a list of items or things or mods i should do to increase the life of engine.

the block itself will last if built as per the dvd\'s,  the things that make it last are the ancilleries like good strong coils and a good water and oil cooling system.

The problem with compression test results is they tell how well the engine is performing and yes lower results mean its more likely to need a rebuild but its still a lottery as to how it will last as it doesnt take into account how long water seals will last.

Very true as well, the compression results tell a story but just like most tuned engines somethings can give even if the compression is good, boosting issues, fuelling issues and so forth.

But as a general guide compression results are a good start and you should deffo have a compression test done on a possible purchase, if i went to view a rotary and the compressions were: 5.8 / 5.6 / 5.7 personally i would not buy as the rebuild would be inevitable, i should my satin black rx with compressions of 7.8/7.6/7.7 as a guide :yes
