It's a 88 turbo II


Was able to do a cold and hot compression test today.


Front 90 psi cold 75 psi hot

Rear 105 psi cold 80 psi hot


Guess the motor is done... to bad because when it starts (pretty much only when cold) it does run great.




Looks like i'll be swapping motors.




How much is the bad turbo motor swap worth (complete with turbos, transmission, ECU all sensors etc)?

I'll probably put in a different motor

 

how much is a low compression motor worth? not much.

You'd make more money ripping it apart and selling the rotors, housings, irons, e-shaft etc, by themselves.

 

ah that sucks.. i need to do a compression test on mine.
it drove about 40 miles when i picked it up though without trouble.. cant imagine it having bad compression.

 

Rebuild the one you have. The best time to rebuild them is when they have low comp vs blowing a seal.

 

disassemble the motor and spec everything out. even if you don't intend to rebuilt it yourself, you can still part it out as everyone said, and it will be a good learning experience.

 

Yeah I've taken apart a rotary before... anyways I didn't buy it with the plan to use the rotary engine.... just wanted to see if it was a good motor before i sell / part it.


Anyways I know most of you guys will probably hate me for this but here is a teaser of whats next for this old rx7:

... ehhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

 

lame.....

 

SUPER LAME I KNOW


Here are some pics of the FC and my other whip:


WHEN I GOT IT:










Needs a lot of work!


HERE IT IS NOW:









Yes the car in the background is my mkiv supra. Part of my motivation for this swap!

Under the hood of the supra:

 

Show off!!!
cool cat is cool.

 

thats not the safest place to store your kittens. what happens when one morning you forget to let him out and u drive off and your big single eats him? huh, then what?

good swap tho should be fun

 

That made me lol I love cats.
Not too bad, but I think the cost of a non Mazda swap versus a rebuild is meh.

 

Exactly! A good rebuilt would cost just as much.

Besides I want a reliable 300hp rx7 that can get 25+ mpg

The entire swap is going to cost less than 3k because i'll be doing all the work myself.

The car was only 850!


I've done a few custom swaps but this will be the biggest undertaking so far. VERY EXCITED!

 

do a write up off the swap, id like to see this

 

You should drop in a re and be happy
on another note a buddy of mine is doing a 1J in his 240...

 

RE?

I'll be doing a write up on this swap for sure. Where should I post it... Other engines?

 

Dude, if that is an original turbo II...... I forbid you to do the swap. Get a ******* gxl and swap it, but don't molest the precious few turbo II's that are still out there.

 

Rolling Chassis.. Much better candidate for the swap..

Please in the name of all that is holy do not molest the TII

 

What a ***** engine.

 

har har har

 

why would you want ANOTHER piston engine car. you have a 3.0L 2j so there no point in swapping a 2.5L in. thats just retarded. it would be cool to have both worlds of the car scene, a bad *** 2jz and a crazy *** 13bt.

i think it would be boring driving the same **** all the time.

i have a mk3 87.5 supra/turbo and its kinda stock ish 7mgte and then i have my 87 TII and i love having both worlds.

 

Because I can

 

hmmmm
I would use a 4G63T

 

Would cost just as much and make less power. Silly greg!


If the rotary could make reliable power with good gas millage cheaply I would totally keep it. It's a fun motor and I love the concept. But communism works in concept too... Lol


I'll be starting a build thread soon...
