Just took out my throttle body because I noticed it was wayyy smaller then the intake opening. Throttle body is 55mm(from a d series enigne?!) and Skunk2p intake has 70mm opeling. It looked like someone tired port matching too, and tried to do it in 5 min. But it looks salvagable, so i was thinking about portmatching it to a 70mm skunk 2 Alpha TB.


b18c1
chipped ECU
skunk2 pro intake ->Whale penis(password JDM powerchamber)
plm Try y hytec reps standard tube ->2.5in w/ only 12 in res/muffler
ARP head studs oem HG(Not relevant?)

Future plans

ITR cams
Pr3 nippon pistons/reuse rod bearings->will probably recheck clearance
Supertech Dual valve springs
Dyno tune

Looking to make about 200whp at about 8600rpm or so

Any advice on anything will be appriciated

You can't open up a 55mm throttle body to 70mm. You need an aftermarket TB. I would not recommend going that big. Replacing the TB is really only beneficial on a turbo or supercharged engine.

I would recommend getting an LS or Type R TB. I think you should get dyno pulls with the aftermarket and stock intake manifolds. Maybe the stock one will make more power.
