Mostly Stock 1987 TurboII... What else to do while rebuilding engine...??
So my 1987 TurboII lost compression in the rear rotor. I don't know exactly why since I haven't cracked the motor yet, although I can tell you it was directly after driving pretty hard for a lengthy period of time. I have no idea how old the motor was that was in there, but definitely not original since the rotor housings have the S5 knock sensor holes above plug and its a 87.
Anyway, so far I've pulled the long block out of the car and have proceeded to rebuild another S4 motor I have. Once it's back together I'm figuring I'll transfer everything to the new block from the old and then drop her back into the car.
My question is what can I do while doing this to make it a bit easier to work on & freeing up some unnecessary nonsense. It's already missing the air pump, 3" exhaust, no cats and an HKS piggyback... Everything else stock.
I do daily drive this and another car so reliability is important.
Thanks Kompressor for the reply...!! I ordered new silicone radiator and heater hoses from eBay. HPS is the company and they come in the color red. I figured since my car is red why not & now I’m really hoping they don’t look cheesy or awkward. 🤷🏻♂️ I also just noticed I ordered the NA heater hoses. I hope they're the same for a TurboII....??? I picked up an aluminum radiator, polyurethane motor / tranny mounts, & ACT Clutch as well. I’ll prob order new plugs & wires today too.
My original post & question is this tho... I’m used to a empty engine bay like in my 1st gen. This 1987 TurboII has just tooo much **** in the way which makes even pulling the plugs a chore. I know I’m sounding real spoiled rn but what I’d like to do somehow is just make this thing easier to service and work on. Here in NY I no longer have to do emissions inspections on the car, just a saftey... so I’m sure somethings can go or be cleaned up. Again everything is there minus an air pump. I’ll post a pic.
with a t2 i always end up checking everything that goes on the engine, about half the time stuff is either stuck/not working or it was hooked up wrong..
if you have the right tools, the spark plugs are easy, and its the PS/AC in the way anyways..
What do I search to find out how to get rid of this ****.....?
Rats nest / emissions delete. Usually mod #1 for these cars, unless you're a purist. With only a piggyback you might want to consider keeping it/some of it, as it's hard enough to get these cars to idle and stay running with a proper standalone and all that deleted.
Thank you DC5 for the reply....!! My brain has so much stored lately it pushes simple phrases out like rats nest and emissions delete 😂
How about this flap door thing....? Anyway to test it...?? Do I even need it...???
What you're pointing to is the twin scroll valve, and what you've circled is the flap it actuates. For a stock turbo, keep it. It improves boost response/torque.
To test, I'm sure there's a procedure in the FSM to test the mechanical portion by apply a vacuum; my guess is you could probably suck on the hose and get some movement, or use a hand vacuum pump. To test the electrical solenoid itself you can use a DMM when the car is running, or test on a bench.
