In light of what one member on this forum is going through ( https://www.s2ki.com/forums/index.php?showtopic=497188 ), how would one inspect a used S2K to determine if it has ever had any forced induction modifications or any other major modification?

 

A situation like this is where belonging to a local "S2KI" community is invaluable. Most of the S2KI communities should have members who have some type of forced induction. Those running F.I. should know what to look for...especially if they did their own installation. Having someone you know from a local community help inspect the car with you can be helpful and give some peace of mind.

If a potential buyer doesn't belong to a local "S2KI" community, I would suggest looking for some common sense signs. Some of which include: ecu wires that have been cut or spliced, oil pan modifications, engine cross member modifications, excessive clutch slip, missing hoses, vacuum lines, etc...

I would also suggest having the car looked at by a Honda garage to make sure no one had tampered with the internals. Maybe even have a compression, and leak down test performed?

IMHO...What happened in your link wasn't caused by running forced induction. Someone (who shouldn't have) tinkered with the engine and did not reassemble something correctly. Replacing a headgasket (or pulling a head) isn't as simple as unbolting a few bolts and slapping it on. There is a specific sequence that needs to be followed as well as a specific way in which the bolts need to be tightened and torqued. My guess would be that the above mentioned sequence was not followed.

 

1. compression test - normal compression or lowered compression (head gasket changed- running high boost)

2. holes in the firewall.

3. Wear and tear of the normal screws.

4. marking on the passenger side strut bar wall - rubbing of the turbine housing

5. Hoses changed - for putting in MBC

6. Additional holes in the front support beam - mounting FMIC

7. additonal wear and tear around where you would normally see IC pipings would of gone.


that's all i could think of now.

 

also possibly holes in the dash or piller for boost gauge

 

Directly under the stock air box is a support beam that runs from left to right and should be painted the same color as the body of the car, to install a supercharger kit properly you need to notch said brace near the passenger side. This is the easiest and first dead giveaway!

 

Wouldnt there be a oil return line tapped in the oil pan...?

 

Not necessary for a Comptech.
