HMMMMMM? the number 7 gives me a solid 9 lbs of boost. I tried a 10 (tiny), got an instand 15+ but it dropped of right away, heated up the charger and belt slippage was an issue with the small pulley.

 

My engine comments were directed to the car owner not the engine builder. My builder, Andy and Dan all alike recommended a rebuild when I went with the charger but I thought my engine was healthy.

 

So is she up and running yet?? How did things turn out??

 

Incase you guys didn't know BlueTII is the owner of unargueably the best S4 rx7 ever made. And those triangular foam air fileters are terrible. they flow crap and are known to melt and cause catistrophic engine failure when your engine sucks in melted plastic.

 

looks nice

 

looks cool

 

DITTO!

 

i dont know so much about the whole best s4 thing...

 

then search and yee shall see

 

still waiting on dyno numbers

 

I hope it stays together for the owner...at least for a while. Are you using solid engine mounts? I would never go back to the stock one's unless I was building it for a cruiser, which would never happen! Talk the guy into a good clutch and a light flywheel if you can.

 

sorry to thread steal, i was just wondering, is it easier to supercharge a carbed 12a than an injection 13b. i had asked about the 13b in the 2nd gen forum and was told it was a bit hard to tune.

 

Nice setup, too bad people talk to you like you did not suggest an engine rebuild. People just do not read the whole topic possibly? Either way, nice work man!

 

Man, rxdoctor's always got a stick wedged up his friggin ***.

 

No one can claim that the engine will blow just because it hasn't been rebuilt. That's a bunch of nonsense. If one does it's because there was either something about to break in it anyways or because it detonated and broke a seal. Added intake pressure in the form of a few extra psi doesn't just blow engines up. If it blows up soon after a blower was added to it, it probably wasn't going to live long anyways. If everything is in good condition inside without any previous damage to any seals inside and it doesn't encounter any detonation, it should be just fine.

 

That wont happen until we can get it out on the street, right now there is too much snow

If you looked at the project link, you would see we installed Banzai Racing Poly mounts, lightweight flywheel and ACT clutch

True, we will see if the engine holds and go from there


BTW it is the #7 pulley

 

I'm glad to see it's a #7 pulley, good choice, How much boost is it making?? As for the engine holding together, it may hold up fine, the 2 biggest factors are tuning and abuse. Since a reputable builder is doing the install I would assume some wideband tuning will take place and given the turbo knowledge of the builder care will be taken with timing issues. As for the driver, well we"ll have some faith there too, nobody would want to spoil that investment. I feel with mine the carb was shitty (trusted the seller) and I put a suitable new one on my new engine and haven't had any problems. Plus, I admit I pounded her pretty good on the first day. Sooooooooooo, reputable builder + a sensible owner + a healthy engine = a long run.

 

Currently, there's too much snow to drive & tune.

Also, there's a PLX wideband permanently installed. So when the weather permits, we'll be able to report how much boost it's pushing.

The distributor is locked, timing is taken care of. Next up is installation of poly bushings kit.

 

The engine was rebuilt by a Mazda dealership back in '91 due to no/low compression. Due to stock speedometer failure the engine mileage after rebuild is estimated at 18k-20k miles. I trust Chris's expertise to get everything tuned safely. I am extremely satisfied with the work he's done so far. I’m not looking to squeeze every ounce of power out of the engine and a lot of the modifications are for future reliability and ease of serviceability. If he or I notice any problems they'll be addressed.

PS. The car will never see Korea, I doubt more than 10% of the cars on the road don’t have any type of body damage. Too many other drivers, narrow roads, tiny parking spaces. I have however seen two other RX-7s here in Seoul, and I think one is an SA like mine (red), the other is an FB (gold). But I didn’t get up and close.

 

Just voicing my educated opinion about not running a fresh rebuild with that type of setup. Was not saying that blueTII did not know what he was doing or that he would not warn the customer about the consequences. Now that I see that the motor has been rebuilt and has low mileage I'll remove the stick from my ***.

Not that I need to explain why I am so adament about doing things right or the need to explain them to the person that is paying the bill. But, I will just for you Sterling. Being that I was a service manager for a period of time I found that alot of Techs or even shop owners would not inform their customers about potential problems. Alot of this was not due to them not wanting to do the job right. It was because of the bad rep alot of shops have and that the techs or owners did not want to lose the customer. Meaning they did not want the customer to think they were trying to sell them they might not need.
BlueTII has a good rep and seems to be very genuine in having the best interest for his customers and I commend him on this.

Sterling, the stick has been up there so long that It has turned to petrified rock.

 

I love Supercharged Seven's. Where about in Indiana can I expect to be seeing this car once the snow clears up?

 

Usually it would be the Warsaw / Ft. Wayne areas. I don’t think the car will be seeing too much road time in the near future. Even after completion it will go in and out of storage. Believe me - it's not my choice!

 

Hello, I gotta inquire how that carb hat worked out for you....

 

BUMP, still looking for feedback on the carb hat please

 

Until about 2 days ago we had a foot of snow, now the suspension is coming apart for the poly bushings after that is done we will take it out on the street and we will know how the carbhat CIA does.
