Mike ill go over this again,
Rpm, typhoon style intake
70mm tb you pick the brand
You don't need anything more than 24lbrs
Lightning maf ( has a quality sensor, no restriction, wide range in the sensor)
Anderson powerpipe 4" to match the maf
Egr , inector maf stuff will all be fixed in the tune.
And trust me the 6250 rpm redline will come quickly with this combo so don't worry about the intake.
P.s. I have a lightning maf fs (cheap) if you want it.89 dove grey lx, turbo blowthrough

Pepboys in denton sells the 4" 4bolt adapter or I usualy mill the flange off and get rid of that problemOriginally posted by 91CoupeMike View PostThat's a good deal, what would I have to use with that to make it work with an anderson power pipe? Or any CAI for my model? That one uses 4 bolts while I need a flange.
Sorry if my questions are stupid, I just want to do this once. Lol
Also, you can calibrate or tune the lighting to work properly with 24# injectors right? Do you use MAFia for that? Or is it all done inside the ECM?89 dove grey lx, turbo blowthrough

Listen, most likely you will eventually upgrade so lets do this the right way. Accufab 75mm "race" tb. That's a full 4" opening nad will be great with the LMAF and 4" CAI. No reducers will be needed filter to tb. Next, why not go with 30# injectors and a LMAF meter. When he adds aluminum heads then he won't need to upgrade those 24# injectors or get a retune. Run a systemax or RPM II intake. If you want to do any mild porting 1" into the heads or intake then do it on the short turn areas and sides. Take it back a full inch into the ports. The alignment of the roof, then the sides are most important.

"Most likely you will eventually upgrade". Those are the famous last words of someone who will never be satisfied. You don't build a car on "if's". He has a plan and he should stick to it. Should he decide to upgrade anything down the road, he can sell the existing unneeded parts and buy and/or trade for the parts that he needs at that time. What you're suggesting is overkill and unnecessary. I also don't see where he says he is going to add aluminum heads down the road. The accufab race throttle body is also a unnecessary in my opinion. It doesn't have the standard vacuum port elbow either. If I remember correctly, there were some tests done years ago that proved the 70mm throttle body provided much more air velocity than larger opening throttle bodies, which is more ideal for a smaller CI motor that is naturally aspirated like what he is doing here.Originally posted by Diabolic View PostListen, most likely you will eventually upgrade so lets do this the right way.

So bigger it is! Actually I made a mistake. I personally run a 70mm Accufab Race tb on my vehicle. It's nice to have a full 4" pipe end to end. I see abolutely no harm in it at all. I also run 30# injectors with a stock 5.0 HO cam that has a stock idle and it drives exactly the same as it did with 19's. The only difference is that I can now spray a 125 dry shot if I want to and add fuel throught he tune. I have seen numersous threads about GT40P takeouts with a TFS Stg 1 cam, 1-3/4 or 1-7/8 longtubes, 3" exhaust, and a 70 or 75mm tb putting down 300+ to the tires. Restrict or time your airflow characteristics with the camshaft and open it up on the ends.

Current set up.
90mm lightning mass air. Just ordered.
4 inch Anderson power pipe, will be picking it up this week.
70mm accufab race TB ordering today.
24# injectors.
Still looking for an intake manifold.
What signicance does the vacuum tube on the a TB serve? It just vents to the valve cover right?

I hate to burst your bubble, but I sprayed a 175 dry shot for years on 19's(as have many others). You don't always need bigger, sometimes you just need better knowledge of how it all works.Originally posted by Diabolic View PostSo bigger it is! Actually I made a mistake.
