I have 1991 300zx i replaced my N/A intake manifold with my friends Turbo intake manifold and know my wont start i thought that buy switching it i should see power gains but ill i get is a free gun show of pop pop pop boom!!! trying to get the car to tern on before this mode my car ran fine.

Question
Should issue Hp gains or not with this mod?
Why wont the car start? What should i be looking for?

 

I have no idea what you just said but I'll take a guess....

You trapped your cat under the intake manifold and it caught fire?

Kidding of course!

The N/A and the TT have the same upper and if I remember right the same lower intake manifold. the only difference was the Throttle Bodies and it wasn't that big a difference at all. If any

You would see more gains from a single popcharger air filter then an intake swap.

Also make sure you put the all the connections on correctly in the proper places sounds like you mixed up a few coil pack connectors.

 

No difference between N/A and TT anything from the TB's to the heads.

 

just found out my friend mistakenly placed the coil wier to the o2 mistakenly and the O2 sensor where the coil wier goes we just fixed it and still wont start did i kil the ecu or some thing?

 

You sure?

You could have mixed the knock sensor connector and the O2 Sensor connector.

 

Knock sensor and O2 are not the same size plug.

Knock and VTC are the same. 2 wire

O2 and coil are the same. 3 wire

 

Thats what I meant! Sorry!
