Thumbs up new motor good!

this is a teaser... i will post something a little more complete...

but vacation comes up on sat, and i have to learn how to embed photos and such...

i am going to include one photo.. and it is a good. one... will make you think...

i was at the dealership all day.. watched the install.. i learned a whole lot... if you think you are a diy kinda guy and going to do a motor change with out a lift. you are doomed...

first point... the master tech i have dealt with, had juan, a senior tech do my car... juan is from puerto rico, this starts out well... juan also has a 13b in a 80 corolla. that does hi 9s. with just nos..

7 hrs.. start to finish... included replacing the flywheel and clutch with stuff i provided... sig is a hint..

also motor mounts were spent. repaced... h2o pump had a weep in it.. new one came with the crate motor.

idle so smooth now... not v 12 smooth, but close...

and the photo.. i took lots of the motors from different angles.... if you have something you need a photo of i will try to help...

beers

nice! Congrats man.

I would be really worried about a botched install. It's good to hear yours was smooth.

Do you know if yours was new or reman?

i am pretty sure they were.. as no cel for the motor that runs them failed...

bad news... the only way to clean them is:

1 track days with 44k in the tank must keep motor over 7500 rpm to clean these valves...

2 some sort of induction cleaner... injected behind the maf.

3 pull the motor and clean it with carb cleaner... that part of the manifold will not come off with the motor in the car...

did i mention i learned a lot...


btw.. that was 55k miles..

I've done three now with nothing more than a floor jack and an engine hoist.

Congrats on the new motor. Get started on that pre-mix.

it went in 5 miles out of the dealership.. could you make a video of your removal style????

the secret for juan was no pulley on the eshaft... and the hood never came off...

btw, when you did the first one how ugly was it???

The first was not ugly at all, just slow. (Technically, it was my second, but my first on my own - MadDog's was my first RX-8 swap, but we did the swap together at his place in NM.)
The second took about 9 hours on my own.
The third took about the same, but I went out the bottom like Juan did it.
Next time, I'll go back to taking it out the top. I hated pulling the power steering rack.

juan took it out of the top... with hood on ... steering rack in place...

i was in awe.. everything was within a .5 inch of not happening..

repitition is the teacher... i was just learning... i just cant think of getting the bellhousing bolts out from a creeper...

as they were getting the motor on the input shaft... we all know how fun that is...

i had a flashback of my first motor install... 66 mustang.. to get the perfect jack / engine hoist / height / angle. took two hours...

the second time 10 min... it was a good and bad flash back..

Hood-on is a bad idea.
First of all, breathing on it will bend it.
Second, why work so hard when it is 4 bolts and self-aligning?
It takes a total of 3 minutes to re-install it and can be done alone with ease.

I was looking at all the sludge on the intake valving. Any worries of these valves carbon locking down the road? I have read of otherw who have had it happen.

were those apv's really as bad as they look in the pics? I can't remember, at what point did you switch to synthetic oil?

you can't pull that part of the manifold with the engine in the car?

which clutch and flywheel went in with the new engine?

Can someone please put some context to the picture for those of us that don't understand what it is or what it implies? Thanks.

I wouldn't worry about it. Every single 6 port in take manifold I've removed from a 13B has looked like that. I've seen at least 3 where the actuators were completely carbon locked shut and it can't be blamed on synthetic oils! That can't happen on the Renesis though.

Yet, I know for sure of one person and I believe two on this board who have had the intake valving(APV's ?) carbon lock to a tune of 5K to replace/free them. This dose seem to be issue on the Renesis or at least on one or two so far. I would imagine the right synthetic would help this but I can say with any amount of confidence.

PS I'll try to track down the original posts to confirm.

So what exactly is this APV and what does it do? Is it part of the S-DAIS? If so now we have to worry about our 2ndardy and Auxiliary ports not being functional if carbon locked?

I thought we had no valves... hehe I know in the rotary itself, but now the word 'valve' being tossed up here sounds awkard and we can't say 100% valve free?

Please excuse me for my lack of the proper names of these components. When I am saying valves I am speaking generally of the intake system and the mechanisms that opens the 2ndardy and Auxiliary ports. In the picture we are taking about the two large cylinders which rotate to adjust airflow to the engines ports. It is these that I worry about carbon locking.

when you shut the car off, you can hear the intake system valves open and close as part of procedure to make sure they don't lock up.

Here are 2 treads about the carbon locking the intake system on RX-8s.

https://www.rx8club.com/showthread.p...uild-up+intake

https://www.rx8club.com/series-i-trouble-shooting-95/ssv-stuck-open-code-p2070-79403/

This appears to be a real problem.

I have been concerned about them locking up too. I drive about 90 miles round trip every day to work and back and it's mostly highway. Mine began exhibiting power loss occasionally in the middle of a long cruise at 65mph. I finally threw a CEL last spring because of it. Since then, I have made sure to rev it out in 2nd and 3rd often. For me, a rev a day really does keep things from getting gummed up. Mine passed the recall tests and is running smoother (and stronger) than it has in a long time. I tried to keep it light for the first tank of gas after the recall flash. It got me 22 mpg and... a bad bog around 7500 the next time I revved it out. Think I'll just be happy with 19mpg and spin it higher more often.

those were the problems i was having and why the motor was replaced.

if i were you and that is still a problem and you can duplicate to a tech, do it...
