Not much, still waiting to get my car back from the shop. they've had it over 2 months, cuz they don't seem to like working on it. New hub bearings, rear end new bushings, new harmonic balancer. My daughter wants her CRV back, and I'm getting tired of fixing it and putting money into a car I don't own! I miss my baby bad!

I replaced my fuel injectors a week ago, and while doing so noticed my throttle body gasket was quite cruddy and torn at one edge. I figured I would have to put in an order with Sewell and wait a week, so I put everything back together and hoped for the best. Unfortunately, I ended up with the high pitch whine that's most likely a vacuum leak. It occurred to me today, I could buy a TB gasket locally for less $$$ and no wait, so I might as well start with that obvious item and see if it's the culprit.
But, having just wrestled with the coolant and air lines below the TB, I really wasn't looking forward to doing so again. I had to replace the dry rotted and cracked air hose last time, and the closest size I could find is a bit thicker walled and a very tight fit in that space. It took me an hour or so to get it on and clamped down. And having to drain the coolant to remove the TB just plain sucks. I can only assume the engineers got lost in a moment of "more complicated is better" and decided to route the coolant lines through a solid metal object instead of wrapping a flexible line around it. I would think you want the air as cool as possible, so warming it with hot coolant makes no sense. Am I crazy, or is the coolant bypass there for absolutely no reason other than convenience?
There was just enough room to wrap a longer coolant line around below the TB, making the air hose connection (disconnected at the bottom left of the pic) way, way easier. It took maybe 5 minutes to squeeze everything into place this time. It would be even easier without the now-unused coolant barbs in the way, but I don't dare cut them off just yet... I haven't fired it up yet -- still getting the coolant level up and ran out of daylight -- so we'll see tomorrow if the engine explodes.
Edit 1: The best I can come up with is to keep the throttle plate from icing up in severely cold weather, but that would cause enough other problems that I don't plan on being out on the road. Edit 2: No explosions (or implosions) in mild weather testing. The TB gasket didn't solve the air leak whine, however, so I may need to replace the manifold gaskets next. In which case, I may grind the coolant barbs off the TB at that time to free up more space below. At least now I won't have to drain the coolant to remove the manifold! Edit 3: After a bit of research, I see this is actually an old and well-worn topic ("coolant line bypass"), with no conclusive numbers either way. Much like with the EGR Delete, actually, which I'm quite happy having done.

Gave it a wash after a month or so. Guess I didn't realize how dirty it was until I started lol. Blinded by the dirt, behind the rear wheels looked like I went mudding and the front bumper had a colony of love bugs plastered to it.

shes still in surgery
Heres a little run down :coil-overs done ( M&S performance) just needs to be adjusted. Wheels on ( Vossen VFs1- 20×9.5 front, 20x12 rear) but the rear fenders need to be rolled and flared 2-3 inches. All new fuel and break lines. And last but not least, the pipes, stainless.

Spent two hours chaning my oil and filter fir the first time in the rain...
That oil filter took 1 hour plus to remove reaching it from the top was impossible. Going underneath and twisting it took for ever as it was installed real tight!

took it drifting yesterday.
(just to be clear, mine's the dark one in the back, not the fancy one plastered with greddy all over, whatever that is)
and today, worked on the sr while the sc relaxed and watched me screw up the 240's motor.

I just picked my 92 sc4 up a few weeks ago....after taking a week to replace the rotted out subframe, yesterday I put in a new thermostat, new serpentine belt, new fuel filter, and a full synthetic oil change with B&G MOA additive. Next week I'm doing plugs and wires, and new tires probably next paycheck. (Winter is just around the corner).
Planned I will be doing a tranny flush/cleaning , new power steering, brake, and fuel lines. I'd like to do thay before the end of the year.
I'm getting her back into the best stock shape before I start the major stuff. First up is gonna be a suprastick shift kit. I'll be doing that over the winter most likely January/February when I won't want to me driving it much anyways.
Then I will start he major planning and gathering of supplies to for boost. I'm probably going to go the supercharger route, but I haven't fully looked into both options yet. Tentatively, I'd like to start that by next winter.
I look forward to keeping in touch with you guys here.
Here she is yesterday in my shops parking lot.
