[alivr6 0]

ok peeps, just placed a bid on the above item, but thing is its for an obd1 engine and mine is an obd2, whats the difference and will it fit on my car.

i asked the owner and this is his reply:

Hi there, Thanks for the interest. The manifolds are from an OBD1 corrado VR6. I beleave the manifolds from engine code AAA and ABV are identical. The throtle bodies are diferent and obviously the ECU. Should not be a problem. Hope this helps,

i believe the 2.9 tb is slightly larger internally than the 2.8, although no doubt someone from here will confirm/contradict this. it will therefore be of no significant gain as you need the tb to to make any inlet advantage, and it is also designed for a big valve head so, it will not gain you anything on the standard set up! unless you plan to purchase for future upgrades i could think of wiser ways to count your cash! bearing in mind a good big valve head is gonna cost you the best part of a grand fitted!

The 2.9 and 2.8 throttles share the same throttle butterfly diameter but the 2.8 has a very pronounced step in the TB mouth, which the 2.9 TB does not have. This was there on the 2.8 to make the throttle response more pogressive.
