need help with this one. i have a 86 n/a turbo. i bought a 89 n/a turbo rebuilt engine from canada with a turbo middle housing. i was putting it together when i noticed that the old intake does'nt cover all the holes in the need engine. it has some extra holes. since this is a turbo middle housing, should i use a turbo intake? my friend was telling me to put some epoxy to cover the hole. what should i do?

 

ok, I'm really confused here? Whats an 86 n/a turbo? Is it a turbo, or normally aspirated car? Same with the 89 n/a turbo engine...is it turbo or NA? Turbo engines are 4 port engines, NA engines are 6-ports. You should be able to count the ports on the engine block.

 

Its an N/A block..the builder basically used a TII MID HOUSING so he can have the bigger middle intake ports. NOw, when he installed the NA lower intake the rectangular hole below the 2 lower intake ports does not cover it. I think NA has a round one but factory blocked off (i might be wrong)..Can's he just block off the rectangular hole with a high temp epoxy???..

 

Bruce Torrentein mention this mod on his video. NA engine with TII mid housing. But he didnt mention what to do with the extra hole.

 

guys, this is TII mid housing. should i get a turbo intake? i don't know what to do with this one.

 

The TII middle housing has larger ports (as mentioned), so it is sometimes used in NA rebuilds to get a little more flow...

Just plug the hole with some high-temp epoxy.
