much like building a V8. Our TBI
people remind me of these stock class guys trying to make a 318 2 barrel run without going to a 4 barrel lol. Big cams and ported heads, etc aren't going to work lol.
Actually the TBI
cam is not small. V8s and the Ford 2.3, etc only wish they had a cam so big lol. The Shelby dak has a .385" lift cam lol, going to a .450" was MASSIVE.
Adding a Weber to a 2.2 is like adding nitrous. Yet you have to look at why. The 2.2 likes air pure and simple is restricted on the intake side with every engine but a T3 lol.
One of the best running NA
engines out there I've seen was a guy that ran a blower B&M intake with a 390 Holley carb and the 280M cam. Side drafts are better but a lot harder to tune. That 4 barrel setup made for a reliable every week end road course car.
You can get the Holley, reman pretty cheap without sensors and an injector, the core TB
unit. You need to run the 2.2 injector and sensors anyway so getting a core isn't bad. You need to use a wide band to find AF
and you need the OTC scanner to see if the 02 is adding or removing fuel. Then adjust AF
to compinsate the best you can.
Being that the Chevy based TBI
units are shorter than Dodge versions you could add a box under it, a 2" tall spacer / adapter for more plenum volume too. From many directions it looks to be a good idea, we just need a TBI
loyal to try it lol
