i have a tdo4h turbo on my 99 civic dx. i think the turbo is the 15g. i was wondering if anyone knows if the 18g from the b16's and gsrs will bolt up to the exhaust manifold? i want to go bigger just dont know what will fit. also if anyone knows what kind of greddy flange the 99 civic sohc uses. thanks for any help.

 

you may get a quicker response in the FI forum.

 

I don't see why it wouldn't...if it doesn't fit you could always get an adaptor plate and run it that way .

 

Yes it fits the manifold but I'm not sure if it will hit the block after installing it to the manifold. If it works let us all know here cause when I did the greddy kit to my d16Z6 I wanted to know the same thing. Never got the ***** to try it though.

Good Luck hope it works.
