I have been doing a lot of research on here and other sites lately. Still kind of unsure what I need to use. My setup isn't in a Camaro its in a 67 C10 but this seems to be about the most knowledgeable site when it comes to TPI setup's.

I have a fresh rebuilt 307 that I have picked up a TPI setup for. The one I got is the speed density with the 7730 ecu (if I recall correctly). My goal is just a nice dependable DD with decent power and decent mpg. My questions are with the fuel injectors, egr system, VSS, and if I think of anything else I will add it.

My setup is as follows.
307 short block just rebuilt
305 HO 416 casting heads 52cc
Edelbrock 2102 cam, roller timing chain, hyd flat tappets
Comp Cams push rods
Headman long tubes
'90+ TPI setup
MSD dizzy and coil
Accell 8.8 wires
B&M Holeshot 2000 stall
Th350 with stage 1 shift kit
Afpr & rail mounted gauge
Efi high pressure inline fuel pump

With this setup I should be in the 9.5-9.8:1 comp range.

Here are the questions I have came up with.

1. Will my 19lb injectors be good for this setup or would I be better off with something along the 22lb mark? I don't have a HP goal in mind just don't want to run lean and have probs. I know if I go bigger I can back off my fuel pressure a bit or change the tuning on the prom. I do have a wide band I can tune by. I have some buddies that are mustang guys and knew I could get some of their 19lb Bosch III and run the normal 43.5psi rather than the 39psi and get approx 22lb. I just didn't know if it would be pushing them to hard. I do know the atomize better and would result in better mpg. If I don't need more than 19lb I cam just run them at 39psi. I have seen other with the same engine/head setup and sim cam break the 300 hp mark. Just don't know if that is where I will be.

2. EGR delete. Is if going to be ok to delete my EGR system and remove it from the prom? Would I be better off leaving it functional?

3. VSS. Since I have a TH350 and no VSS I have read that I can remove the VSS from my iron with no ill effects. Is this true?

4. O2 sensor placement. Since I am running long tube headers and true duals what's goin to be my best placement and options? I was figuring in my driver side collector with a heated O2. I know there I am only goin to be getting readings from half the engine but better than just in one runner.

I know about the vats I am either goin to remove it from the prom or get a simulator.

Thanks for the advice and help in advance.

Justin.

 

since you dont' have to go through emission I would delete the code 32 and change the egr vs mat setting as well as the air. You are correct on a heated o2s that far down in the stream. I would install southbay fuel injectors bosch 3 19#hr. The vss would be a wise idea to install to help when you come to a stop to control the iac.

I will get that VSS. Will it run a aftermarket electronic speed-o for when I upgrade all my gauges?

I was thinking about just buying a .bin file for the prom. The only company I have been recomended to right now is pcmforless.com. They are wanting about $150 for the file with settings for cam, vats removed, EGR removed, and if I change injectors new coding for the injectors. I just haven't messed with any GM programming yet and I need it running soon so it looks lime I am goin to have to just buy a base map. I can always may another to play with and fine tune later on.

Is there anyone on here that would be good to get/buy a base map from?

 

I know this is more of a matter of opinion but what would be the best sparkplugs for this setup? With having the tpi system, ecm, and MSD ign I am not sure what to run.

 

I run nothing but NGK in mine and it runs great.

 

I have always ran NGK in almost all of my Imports other than Europeans and I run Bosch in them. I wasn't sure which to run in this. What plug and temp?

 

What water neck/outlet would I use? The stock tpi onr is like half the size of my stock one and my radiator hose. What outlet would I need to get? I have thought about the aluminum swivel one but everyone I have talked to say they leak.

Not sure of it makes a diff but I have tall aluminum valve covers.

I have a 1985 TPI Trans Am and i need help with a wiring diagram because my fuel pump is strait wired and my mass air flow,fuel pump,and cooling fan relay pig tail are gone can any body help its a 305 H.O. heads PLEASE HELP It acually looks like they've cut the wires out of the wiring harness all i see is two thick orange wires that have to be hook up in order for it to run

 

I didnt even think to check on there. I have a build thread on there.

 

I know there wiring diagrams on here. I have downloaded them and have them on my phone. I can't tell you right off where they are.

 

Please don't hijack you can see them at gearheadefi or chevythunder.com or austinthirdgen

 

Its been awhile since ive done them. I couldnt tell ya anymore unfortunately. Sorry.

 

Chevythunder is where I seen them.

 

I ordered that waterneck it won't be in til mid next week. Oreillys got it on they way. They only want $14 for it and pay for it when its picked up. As long as its the right one that solves my prob.

I have noticed some people have a air foil in their throttle body. Mine does not have this. Is it goin to make a diff at all not having it?

 

the claim is increase hp but my sensitive butt dyno can't tell a difference.

My Bosch gen III 19lb injectors came in today and I made my EGR block off plate so I was able to get my intake on.

Here is where I have the motor to now. I need to get 4 lower runner bolts, 4 throttle body bolts, locking header bolts, alternator, aluminum power steering pulley, also have to make a custom CAI. I also think I am goin to get a new harmonic balancer cause mine do appear to be in the best of shape.

 

looks like your airfilter is off a ramjet 502

 

No clue it was with the tpi setup when I got it. I thought at first it was a K&N but its a GM Performance.

 

Does anyone have a single Accell 8.8 spiral core rfi suppression wire laying around? One of mine has a bad spot on it and I don't really wanna spend $90 on a set over one wire. The one I need is 44" over all length with 90* plug boot.

 

yes it is a k&n made for gm performance 12490257 ramjet 502 same as the rc-5000, looks good

 

I figured it was I cleaned it with my K&N recharger kit. I like how it looks but I want a cold air kit so I might have to get rid of it.

 

I will send you my address again when you done with it. lol

Posted it up.

 

Ok got another question.

What's the knock sensor I need? I wasn't sure if the 305 and the 350 sensors are the same or where to start looking for one at

 

I believe It a acdelco 213-91 gm#10456019 you need one for a 90-92 tpi 5.0L

 

What are the size of bolts that go into lower plenum. The longer ones that go into the bottom of the flange. I need bolt size, thread pitch, and length.

 

All the runner bolts are M8 x 1.25. You'll need three different lengths: 30mm, 40mm and 55mm

 

I have all the runner bolts except the 4 long ones and the 4 throttle body ones. Well I have the 4 tb ones but I want them in stainless allen head

 

Just thought I would post pics of the Lokar throttle cable and bracket for anyone interested in them.





I plan on making some brackets to hold the cable up above the runner using some SS clamps and the upper front and center bolts.

 

Does anyone have a link to pics of the connectors and say what they go to with wiring colors?

 

I have no oil pressure sensor and the wiring just has 2 female spades crimped on. What sensor do I need? Is it just goin to be a universal sensor or a specific one with the tpi sensor? Also can I use this sensor for a aftermarket gauge?

a C1804A may work gm 19190665 I just checked a switch and its a n/o switch until you get oil pressure, you would not connect the idiot light just the gray and orange.

this was a 85-87 corvette and camaro tpi oil pressure switch.

 

Mine only has 2 wires though.

 

If you look at the link with the diagram I am missing the tan wire to the I/P. What is I/P? I am figuring its for the idiot light but not sure.

 

I/p Is instrument panel the ground side of the low oil pressure switch idiot light.

 

Ok cool thanks thats what I thought. I won't need that anyways cause of my setup.
