Type1 to Type2 intake manifold 101

Everything you need to know about this mod is located in this thread. I will not cover the removal of the intake manifold due to the fact it's a 3-5 hour process. These pictures should help you understand what you can keep intact when removing the intake manifold:

Front:

Rear:
Intake manifold rear (The pink circle indicates where your EGR pipe -> Intake manifold pipe would remain intact during removal.


There is only 1 modification needed to perform this swap. A item called the PAIR Valve needs to be blocked. This entire unit is bypassed on all type2 engine. You will have to fabricate a metal block plate.

Where the unit is

unit blocked:


If you look at the rear picture of the intake manifold (2nd picture) and compare them to this picture, you can see how the entire unit is bypassed.



Why a type2? Well the fallowing image shows you exactly why. A 5-10 HP increase can easily be added. A port/polish could prove to increase a greater amount of HP.




Extra info:
The throttle body from a TCS type2 will not swap with a non TCS type1.
Everything else is swappable and identicle. that includes the EGR pipe, EGR system, screws,nuts,bolts you name it.
The lower plenum, middle plenum (VIS) is identicle on both motor.

Nice to see you finally got a chance to do this, I know you had it planned for a while. Hopefully you'll pass smog too now that the EGR system is all cleaned out.

So ballistic, what is your take on this mod? Is the butt dyno happy?


To reduce your NOX emmissions you may try retarding your timing a bit. There is an adjustment inside of the black control box. Check out the service manual or I can give you more details. Try running some fuel injector cleaner also. That can make it run a bit richer (leaner=more NOX).

-Matt

P.S. You should have stuck with a 3 way cat instead of the high flow, esp in california - HC, CO and NOX.

P.S.S. Try using some GM top engine clean or berryman b12 through the PCV valve. That breaks up alot of the carbon deposits that cause hot spots which in turn cause NOX. Just make sure you do it at night cause the smoke is gonna make it look like your cars on fire.

Ballistic, thanks for the great post! What's a 3-way cat(vs say a Magnaflo that I have on now?) What kind of thickness plate did you use to block off the PAIR valve? Are you gonna run chipped or stock ECU for smog? Let us know smog results. PM me your number and times to call if you're OK with it, I would love to talk to you about what you've done so far to your car. Again we all really appreciate the DIY! mods want to sticky it in the DIY section?

PS sr5guy, although it seemed obvious, I never thought about running a cleaner (I'd likely do Seafoam) at night, thanks!

how hard is this to do?
is there a complete DIY to swap a T1 for a T2 intake?
I think you are going to need a T2 ecu to make it run at best how good do they run on a T1?

I don't think there's a complete diy, but I hadn't seen this thread before either.

I don't think you'd need a Type II ECU, you're not really changing that much by swapping the intake manifold. Getting a chipped ECU is probably the way to go even if you don't do a manifold swap. Go over to acuralegend.org and PM Telion .
