What would you do? Sadly I shoudl have seen this coming a mile away and knew that in no way was i going to be able to just put the engine in storage for a rainy day.

Can I SC an 85? the engine is actually a 86.5 US but will go in an 85?

I wasnt going to SC at all. BUUUUUT since I have this engine and it is out of the car. Why not?

What do you guys think? And what should I do to this thing to "do it right"

Discuss. Please!

I like DR's kit, will it work? DR please chime in!

 

The 86.5 engine is essentially the same as the 85, but has updated:

Pistons
Cam gears
Head gaskets
Intake gaskets
Dipstick and tube
Timing belt covers
Outer valve springs
Cyls ¼ valve timing
Timing chain tensioners
Timing belt tensioner, tensioner arm

Late 86.5 also have socket head bolts for the cam covers.

 

put in S4 pistons to lower the CR then pump up the boost

 

Perhaps this thread will help...

short answer... Yes

 

#1. yes
#2. yes
#3. works for me, but it is your car to do with as you please
#4. the list is long, but a basic rebuild before adding a blower is a good thing/ doing blower prep is even better
#5. yes--but confirm with Dave.

"discuss:"

if it's a stick car, I suggest looking into clutch upgrades---a slushbox can be modded too.

exhaust system, fuel delivery system, ignition system, etc, could also need to be upgraded as well.


too many folks throw on a blower and expect everything else to live forever without thinking of what the added stress does to the rest of the car......John Kuhn put two turbo's on a 150,000plus mile old (I think that was the number...) S4 and immediately trashed the clutch on the first dyno pull----think about it.

Whats the mileage of the engine?

If you do plan on boosting it I like the idea of throwing S4 pistons in it. They should be cheap but make sure you get pistons in the same tolerance group.

With the engine out and on a stand, i would consider refreshing the seals and gaskets. If your going to put 7K into the supercharger install I would think you could be doing yourself a favor by refreshing the engine now.

Roger has a friend/customer who's cherry low mile 86 has a number of leaks after sitting for 5 years or something. With that in mind, i would just reseal everything and then your starting completely fresh.

If you do just gaskets and seals you can buy the engine kit for less then $500. If you do a valve job (not a bad idea but cost goes up significantly) you would have a really great starting point for a boosted engine.

 

Buy Brendan's stroker crank and go nuts. Then supercharge it later.
