#350227 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 :) :D :? :thumb: :woot: :woot: :woot:

#350313 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.
