TPI Speed density system from 91 corvette w/ weather proof computer

Beginning installation.

Ready to go in car.

In car

I'll post more as I go.

ECM

After fixing a few wiring problems it fired right up. First thought is Its gonna haul some serios a$$. You can really hear the cam, It's the Biggest cam Comp cams makes for TPI engines 260AH-14

Could you also post, IN DETAIL, which wire goes where in comparison to the carburator set up? IT's looking real good!

You lucky Bastard Absolutly beautiful!!!!!

Looks nice ... Hate to be second guessing you, but are you sure that is where you want the ECM... I realize it says all weather, but where it is at it could even get ice and snow. I think I would at least put some kind of cover over it .....I put mine in the corner of the trunk it tucked away pretty good and doesn't take up much space. Not knocking it ....It Looks very nice you will be pleased when it is done

LS1 in and running :)

absolutely sexy.

Looks very nice. Quick question I see they are older heads not top bolt valve covers so did you have to elongate the two center bolt holes on each side of the intake to bolt on. I have done that with throttle body intakes but not seen it done on tuned ports. Hope she goes even better than you expected.

Anyone using a stock TPI ECM, it will bolt right up in the original Fiero ECM location using a 88 2.5 ECM bracket.

Nice to see someone going from carb to FI..

I trust you're going to be replacing your fuel pump.. You'll need a high pressure pump for the TPI..

I was going to point out that the Vette intake didn't have an EGR valve.. (Camaro/Firebird did). But the cam you're using has enough overlap that you can do nicely without the valve.

the stock GT pmp is good enough to run a northstar at 100% , i don't see the problemwith running a TPi setup. More than likley he had a restrictor to reduce the flow from 40psi stock down to the 4-6 required by a carb.

chris moore ran a stock pump on his N* for 5 years , then swaped to a turbo trans am (89) pump ...no difference in performance

Answers To a few questions.

I do plan on covering the ECM to keep junk off of it, it's the Stock weather proof ecm from 90-91 vettes. My TPI system Came off a 91 vette, and it does have a EGR valve. The vette Alum heads didn't have heat risers in them, so a tube connected one of the headers to the intake. I made some alum block-off plates as I'm not using the EGR system, I had it removed along with the VATS from the Prom. The plate in the center of the picture is covering the EGR inlet

The two center bolt holes did need to be Elongated, otherwise its a direct bolt-on.

Looks familiar!!! You're going to have fun!

Wow they both look nice I think that is the first time I have seen a pic of California kid's engine. Good idea to get rid of the EGR I did that as well. Eventually I want to get the LS6 intake with no EGR. Once again looks very nice

Thanks!

Looks great. I love the look of the TPI. Here was mine, albiet in my Firebird:

My other reasomn to jump into this post, other than praising your work, is to ask why don't more people use the LT1 intake. It seems like such a better fit to a SB Fiero with it's high winding ability versus the TPI's low end torque.
Just curious...
BTW, this is why I mentioned it (and agin in my Firebird):

Thanks. Mine is pulling strong up to 6,200rpm, torque monster all the way! Running opened port matched plenum/52mm twin throttle body (it's asking for the 58mm)

I am curious on the rpm range with the LT1 intake and it's affect on torque/hp, if you have the info available. Not that I'm going to switch, but it would be nice information to have.

When I had the TPI, I had an LT4-hot cam, ported intake and siamesed SLP runners (not in pic), 48mm TB, TFS TW g1 heads, and 1 5/8" TES headers. It maxed out at 5400RPM. A larger TB and 1 3/4" headers would have helped, but the RPM peak would not have moved much. These are typical results from the thirdgen f-body groups. With just the LT1 addition, I can easily hit my rev limiter at 6200RPM, still spinning the tires as before. Results at thirdgen.org show approximately 30-40hp gain over the TPI. Check out www.LT1intake.com for more info. BTW, John Millican is a good guy, but I'm not associated with him in any way. So I'm not trying to sell his product. I did mine myself.
