1991 745T Mods and Upgrades
As I said, your engine sounds O.K to me, Piston slap is far from uncommon on these engines, especially when cold. They ARE a fairly large bore four cylinder engine after all.
f the valve clearances were set when they did the head, then should be no problems.

Got some work done on the 740.
It is moving very slow, but is coming out great
Here is a basic breakdown:
Headunit: Alpine CDA9883
Door Speakers: 4x JBL 508GTi
Subwoofers: 4x 8in Revel (same speakers found in the Ultima Salon2)
Amplifier: Harman Kardon CA5250
Here are some teaser pics:

Amp installed:


Subs:

Ran 1gauge powercable (phoenix gold breaker near battery and Inline Fuse holder in the rear):


Got most of it hooked up. Still need to run one more RCA cable (Belden), then finish soldering the RCA ends to the lines. Still need to cut holes out of the custom panels I made for the subs to go in the floor where the two cargo doors are. I also have to finish sealing the rear door speakers. Then it is just a matter of hooking up the new remote power switch to head unit, finish the headunit mounting location, and putting the fusable link I made in the Inline Fuse holder for power. Everything is hidden which is pretty cool.
Then the testing begins. Hope fully the ground I choose is quiet, and I wont have to redo anything...
now, if only I could get the car to sit a like it does in the sig pic

Thanks Tech.
Here are a couple more pics:
Wiring locations (might re-route some after testing)


Stock grill (had to modify the door panel to accept the new speakers as well as to get the stock grill to work)

wasn't thinking about that at the time.
dont see it being problem though.
Got sick this weekend, and was only able to finsihd the rear RCAs..
Finished soldering the Rear RCA Cables:

Basiclly finished with the wiring. Just need to finish the sub mounts and route the RCAs to the amp:

How it looks with the carpet in place:

Only 2weeks left in this semester of school, so focus is on that.

Where did you get the hard ic piping. I wanted to replace the passanger side piping. Both the ic pipe, and the pipe from the air box into the turbo. I just bought the car and the driver side pipe is hard, the other are two soft and spongey. Thanks
it was from the supra motor in the guys 745 which we gutted. I saw it and said: hey, that might fit and it did...

I'm considering options for setting up an amp/sub. Yours looks very good and has given me some ideas. That is a massive amp. I wouldn't be going with as much power or as many subs. Anyway, where will the subs go? Have you installed them yet? Pics?
They will go in the two floor openinges on the side of the middle opening where the amp is.
I have the 1/2" sheets cut to size. I just need to cut the 3/4" sheet and glue the two together. Still need to cut the openings but they will have a custom flush mount grill, so if you look, the two pockets will be slightly taller (~1/2") but you wont see anything....
Maybe pics later today.
Had some time today...
Finished soldering the front RCA connectors.

Just need to connect the purple wire to the head unit, then attach the bass level adjuster to the dash, then connect that cable... Then the front will be finished

Here is where the subs will mount ( need to cut the 3/4" and cut the openings, then carpet it, Make the grill, seal it, and screw it to the metal.):

Some more pics of cables...
Here is the ne battery posts we are using:

Here is the new Ground cable for the alternator:
