I think youve got the S4 rear iron but I cant be sure. If you want to be safe, you can get the oil pan brace from banzai racing.

Its basically a thick hunk of metal you bolt over the oil pan that is supposed to keep the motor from twisting itself apart. I assume you are worried about the dowel pin cracking?

 

Maybe I am wrong but I thought only the S5 center iron had NO egr valve on it so I would say the center iron is DEFFINATLY a S5 (not sure if n/a or T2)
looks like a S5 housings and a s4 rear plate

 

Sounds like I've got a winner

 

Its an S4 front cover because in your exhaust picture I can see the swing arm for a mech. omp

 

Bah run it til it breaks then drop in a 13bre.

 

Actually its a 1st gen front cover.........hence its ability to be bolted to the 1st gen body.

You my friend have a mis-match, multi generational keg on your hands.

Only way to get true answers is pulling it apart.

From the outside I can see:

S5 Housings
S4 Rear plate
FB Front cover
S5 front plate

Sometimes mutt's make great pets though...........othertimes...................

 

I need to pull it out for a portjob anyhow so I'll just throw a S5 rear plate on there and call it a day.

Plenty of guys making ridiculous power with the TII motor.

 

I hear ya !

 

I have a full set of S5 irons, if you're interested, pm me.
