First few set of pictures was from BigTurbo's motor rebuild. Nothing drastic was done on the daily driver, but it does have an e6k and some other goodies. We're going to do several dyno sessions on it to tune the exhaust later. Will post those next month. The last picture is a few motors I'm doing for some locals. Miltsthemans turbovert motor is there, waiting to be ported and assembled. The center FD motor is a half bridge thats getting dogmission and a to4R bolted to. I'll post pictures of those rebuilds here shortly.

I like your Wankel :-)

Purrty. I started my rebuild today, I can't wait to have a running 7 again.

Good job.

Jager 11-29-04 12:41 AM

They look great

RotaryWeaponSE7EN 11-29-04 12:56 AM

Very nice and clean.

RotaryEvolution 11-29-04 01:02 AM

looks good, most people don't realize that it only takes about 20 minutes to disassemble and reassemble a rotary but about 10+ hours is all the cleaning and prep work. :D

Syonyk 11-29-04 01:09 AM

Add a few hours if you don't superglue the corner pieces of the seals in. It's also occasionally a pain to convince the coolant seals to STAY PUT (at least with the teflon coated ones - not sure about the stock ones). But, yea, they're insanely simple engines to deal with.

looks like he glass bead blasts his housings also, my prep work took forever and his looks even cleaner so i'm sure he spent quite some time on his engines. :)

mcnannay 11-29-04 01:19 AM

yeah i had to laugh when i torqued down the last tension bolt on my engine, i remember being pretty hesitant about rebuilding my engine, but damn it was soooo simple! great experience, can't wait to get some money saved up to rebuild the 13b in my fb, and do my first port job :D

Clearancing and porting takes the longest time. Hand polishing rotors also takes awhile.

The 1st motor I did with a friend, the last one we went to torque down, wouldn't screw in. We had impacted the T bolts loose on disassembly and it must have been so corroded that it ripped out that threads!

Couple shots of forum member MiltstheMans's motor all done.

i used to be that intricate until i pulled apart a motor i fired up and the carbon had already covered half of my previously polished work. i now just clean them up as good as i can without huge amounts of detail.

Turblown 12-09-04 01:24 AM

We you premixing also? I plan on pulling apart one of these motors withink 5-10k miles to check things out inside. I am curious if the carbon buildup will be less or not with the polished rotors.

ddub 12-09-04 01:38 AM

Polished rotors are hot, though I don't think I'd ever take the time to do it. I'm too lazy and impatient =|

FC3S.USD 12-09-04 01:43 AM

That would be really good 1revvin7. To actually pull apart the motor again and see IF polishing the rotors is anybetter ( more/less carbon build up ).

jacobcartmill 12-09-04 03:01 AM

i wish i had enough time/cars to be able to build an engine, drive on it for 4 months and take it apart just to see how bad the carbon is inside :)

Yea there is a lot of stuff I want to check, for example how fast all the seals wear down, how many miles does it take for the corner section of the apex seal to start cutting away at the rotor housing, etc....

RotaryEvolution 12-09-04 10:41 PM

where the carbon really builds up is in the exhaust ports, which sucks because polished ports flow best compared to rough ports which can cause turbulence. you can't do anything to keep carbon from sticking to the exhaust ports with the exception of possibly a water injection system working regularly.

silverrotor 12-09-04 11:13 PM

1Revvin7, busy shop you got going there. Looking at these pics makes me miss my rebuild of my Engine. Oh, I've replied back to your PM. ;)

RotaryResurrection 12-10-04 02:03 AM

What's the red stuff on the rotors, atf? Ports look nice. I thought mills' motor came from a car that had already been rebuilt? He was going to bring that down here to get it installed, glad he found some local help ;)

SureShot 12-10-04 08:12 AM

So - what's the red stuff on the side of the rotor? Assembly grease? ATF?
