Just picked up a 91 si with this set-up, can someone help me figure out what the heck is going on here. Rod's were ready to bust through the block and by looking at the exhaust side, i know thats not normal, the dizzy on it is td-02u.thanks guys

 

forgot to mention, pm6 block while the head says pm3...

 

Ok so the dizzy can be 91 si, Can the stamp pm3 be of a crx si head?

 

Is the head Vtec or not?

 

Kinda looks like a stock 91 si

Unless its a d15 head or obd1+ its the si head, the civic and crx have the same motor and the si had the only mpfi d16 in obd0. The a6 block is the si block and si dizzy.

 

Non Vtec.

 

The guy i bought the car from said everything is original on the 91 crx si, 2nd owner. Block says d16a6, Trans is an L3 with 2 grooves, Now the Head being a pm3-5 and the IM being without the mpfi label is confusing me.

 

You have a stock Si, nothing weird

 

Yep, stock si. The head was made in 1990, so unless it's a d15 head, its the stock d16 head.

 

The mpfi logo can be shaved off pretty easily. Same as the valve cover can be if you want just the H or nothin at all

 

Clean car though, what's your plans? Like my crx's ls swapped

 

Thanks guys, My plans is to restore it 100% Original Oem and enjoy it, but who knows how it might wind up.
