what is so bad about gen ii engines?

You can make a TB adapter for dirt cheap to use the 3500 plenum, then just find a 65mm TB at the junk yard and bolt it on. No sense in purposely limiting power.

It's not so much peak power, but gains throughout the RPM range that really makes it worth while to use the 3500 UIM.

You'll probably lose 10 or more HP on a cammed 3x00 using a 56mm TB/3400 UIM VS a 65mm TB/3500 UIM. The engine will also pull a vacuum at WOT which is a huge indication of too small of a TB/not enough flow. I've seen it on the dyno several times.

Its your car man, You gotta decide what direction to go with it and what you want. If you want all out power, the 3500 the place to start. 3400 still makes good power, and still can be made into a strong motor, but it wont achieve the power a 3500 will. If all you want is a cammed motor, just get a 3400. They are usually cheaper from a jy, and easier to drop in place. But if your wanting a cammed motor, and you plan on getting all the work done to do that, the price difference between a 3500 and 3400 doesnt matter. My .02

well i have two options 1. get a 3500 and swap just the intake- 2. just use the whole 3400 sfi. i think the 3500 with just the plenum+tb off the 3400 would still have decent headroom for a cam. what do u think?

[19Cutlass94]

Close enough its not worth the trouble your going through in this thread. Just use the 3400 intake. Later on down the road, if you have money burning a hole in your pocket, upgrade then.

[SwiftDrift]

yeah people dont like the idea of older parts on newer motors. if it is as bad as putting a small port intake on a 3400, then obviously i wont use it. but they seem pretty damn close so i just wanted to know exactly how close.

[19Cutlass94]

The 3400 intake is not a bad intake. Just use that. I am, and its working just fine on my motor!

[SwiftDrift]

how will i know exactly what tb to look for in the junkyard???? and whats the big deal, i hear the 3400 intake isnt bad, though the tb does seem a wee bit small. and everything else is gravy, i know people who i can get trannys and axles and everything, except suspension, i will have to save up for that. but really how bad can the 3400 intake restrict the 3500?????

If you know where to look you can get decent used tires for free. The local drifters buy brand new tires for $70 each mounted for drifting which is a really good price. These tires burn up nicely too unlike other cheap tires that will chunk away once they're hot.

[34blazer]

Anybody mention the cost of tires???

[caffeine]

Ya a proper suspension setup will cost more than a motor swap. Steering angle would probably be the first thing to address IMO.

I guess I'm just confused about your entire project. You are wanting to build a Camaro for drifting and are talking about all of the mods needed for drifting, but then you are concerned about the cost of a TB and adapter. Sounds like you need to make yourself a plan and figure out a budget before you go much further along. It'll help in figuring out what questions you really need to be asking.

Several paycheques? Most pull-it-yourself places seem to only charge about $30 for a throttle body. If you have a drill and a holesaw set you can make yourself an adapter plate for $5-10. I did.

agreed.

honestly, if you can't swing a junkyard TB, you might be better off going job hunting.

while im at the junkyard, after purchasing the 3500, i was going to get a 3400 sfi plenum and tb. most likey dirt cheap or free... vs. saving up several paychecks to blow on a tb and creating an adapter to use it.....
