Due to the off set different of the hole... you will need to cut it a an angle to ensure
smooth flow. The flange adaptor(spoilt) in the picture is a bad example......

The gsr head in the picture original bolts have nt been remove. It should be removed and fitted with sunken head screws...

For SOHC 4G92/93 head.... no space for flange adaptor... so just modify the holes and cut off some area of the b series intake to fit it in... Here's some pictures...

Thanks brudder for sharing. It's not easy to find ppl to share fully. When I did mine, I'll post the technical drawing with dimension.

But it's gonna take some time as I'm kinda busy with some other projects at the moment
 
Bros....
U are most welcome...

Well, not alot of ppl are willing to share what they know. Lot of different type of ppl in forum. Some likes to share but dunno what they are talking. Some knows what the talk and likes to teach ppl, but when it comes to the important things, they would just keep their mouth shut. And I think alot of ppl are not willing to share and keep things to themself.

Less n less ppl will share what they know. Sooner or later, the Malaysia automotive will end up like other sports for being selfish.

Thanks again.
 
True...very true...
Nowadays with internet you can learn abd DIY alot of great stuffs.
However, if got share share info... will speed up things and waste less...

We can do it...so Just do it.

Lolz. Thanks e-tech. Just got it installed. Since my engine is off from the bay. Still waiting for the engine to start. Run in and tuned.

But I went for the modification way instead of adapter.
 
no need to go through all the trouble in mating the flange with the intake unless ur buying genuine skunk 2 intake.the fake skunk2 is out with 4g93 flange.

I'm using a B16 stock manifold. Not skunk 2... I'll expect improvement on the low end response due to the shorter runners and bigger volume plenum. Well, and the answer will unveil when run in completes. haha...
