My compression tests. I'm confused. I guess my compression is super low. I did a wet test and it didn't change much.

Compression test:

Compression test cylinder 2:

Compression test cylinder 3:

Compression test cylinder 4:

Wet compression test cylinder 1:

No smoke out of the exhaust while driving. Had a friend hang his head out the window for a solid 5 minutes. Did boost and vacuum pulls.

According to your gauge you're in the green...what's the problem?


I've always used compression tests as a relative number, not an absolute. 140psi vs. 180psi vs. 210psi doesn't really matter to me...all that matters is that each individual cylinder is within 10-15%.

If you really want to know if you have a compression issue, do a leak down test...it's the only way to know for sure.

I'm worried that after 5 pumps its only at 60.

Than do a leakdown test.

I've watched your videos like 3 times...it seems all fine and dandy to me. But seriously, if you can't sleep tonight because of it then do a leakdown test. It will give you 489% more info than a compression test.

First time ever doing a compression. Test so I'm really just shooting in the dark here. I think I'm just worrying about nothing.

Just bought these because my other fog lamp broke (cheap ebay **** without a replaceable bulb)



I use them mostly as driving lights so other people can see me, but with all the fog we have had lately they will help.

Also got these in the mail:



Locking downpipe fasteners.

Grabbed some RX-7 studs and just need to get some resbond and that will be my fastener plan.

Haven't worked on mine much because this thing has been taking all my time:

Things seem in good condition. I just know I'll get a bit more money if it is buttoned up nice and looks good.

You got that right. Craigslist would call that a fully refurbished turbo kit.

Wait. No it wouldn't. Nobody on Craigslist knows what that word means.

Psh, I'm an engineer, I don't speak gud and them fancy words don't help me with math any.

I have actually managed to go the past 3 years without writing a single paper over 2 pages. Fancy words are not my forte.

I'd take a 3-page paper over a few math problems any day. Linguistics major FTW. Actually no -- FTL. I'm a car salesman with a college degree

Put some time in this morning mounting my passenger seat. I now have matching fixed back seats and 6 point harnesses. The passenger seat is mounted to the stock sliders.

Harness:



Mock up:




2 metal straps to connect to the seat:



Which are bolted to the stock rails.



Big washers to prevent pull through:



Boom:









Also, found this above my oil feed line. Could it be coming from under the head?



Bought this to try and track it down:

How did your driver seat feel on your drive to/from seattle?

Really great on my back, but my *** bone needed a pillow. The way I had my right leg up meant that the bone was right on the seat. But otherwise it did fine. We will see what my gf has to say after this weekend's drive to seattle.
