Do you need a special set of heads for the tpi system. The heads that I have are
New Dart/World heart-shaped chamber, 200cc intake runners, straight plug heads with 2.02"Int/1.600"Exh swirl polished stainless valves with undercut stems for even more flow.
and I want to make sure I don't need a special set of heads for it. First timer with converting carb to tpi so any help would be helpful.

Depends on what year your TPI baseplate is.
First of all, they need to be center-bolt heads,
If you baseplate is for an 85-86 setup, bolt patern will all be on a 90' angle.
If it's for an 87-up setup, the four middle holes will be on a 75' and the outer 8 will be on a 90. Check your heads, see what the patern looks like.. either or will work, just depends on your baseplate.

 

Ok so the intake that I have on there right now is the Edelbrock Victor Jr (maybe that will help).
Sorry I do not understand what you are asking me to look for. I have not brought the setup yet but got one in mind and want to make sure I am buying one that will fit on my heads that I have.

 

Do you have MSN/Aim?

 

I am at work but will be home at 3. I live in new mexico so I don't know what time range you are in but we could meet up later on it.

 

If you have a victor jr, you have the older style heads, you will either need to find a 85-86 TPI base plate, In 87, they changed the bolt patern for the intake manifold on the heads, and the four middle holes are a bit more angled than the older style heads. These base plates will still fit, with a bit of grindage on the holes for the baseplate. i have seen it done.

if i were you, i would find a 85-86 base plate, or buy something universal from edelbrock

I bought my engine from tuff dawg engine on az about 4 years ago. And I was new to working with engines. So like a dumbass I cut the wiring harness because I was going with a carb. Now I relize that I could of keep it tbi. So with knowing what I do I would like to make tpi. And there is a guy on here that is going to sell one to me. But before I buy it I want to make sure it will fit.

 

Easy enough, just ask him what year the base plate is for. If it's for an 85-86 you will have no problems, if its for an 87-up you will have to re-drill the four middle holes on the baseplate.

this is what you are looking for (base plate wise):

If you don't mind me asking what all do i need to swap over to the tpi. I just want to know from someone that has experience with tpi so I am not missing anything. This will help the install go by a lot quicker.

Well, obviously you will need the complete TPI system (base plate, runners, throttle body, fuel rails, fuel injectors.. etc.) the main thing your going to need is the ECM and harness to power the TPI. you will also need a distributor/cap for a TPI gm to plug into the harness. If the TPI system you are buying doesnt come with the harness/ecm, look hard on ebay.. they are laying around. Also, make sure you have atleast 22lb injectors.. its not necessary- but is recommended. Depending on if your doing speed density or mass air flow.. you will need a few sensors for the air intake. It all depends on what ECM/Harness you happen to get ahold of. If you get a MAF harness/ecm, you will need to buy a mass air flow sensor and the air intake for the vehicle you have to adapt the maf sensor. i myself am only farmiliar with the MAF setup as its easier and more 'universal' to newer vehicles. If you do happen to get a MAP (speed density) harness/ecm, you will have to do further research on what sensors your going to need.

Thats just about the wrap sheet.. may i ask what vehicle and what year this is going in?

I have a 91 camaro. It had the 305 with over 150000 mile on it when I bought it from my mom. She told me she would sell it to me if I would not make it a race car. So I told her ok(hahaha). So I drove it down to where I was station at. It was super slow. SO my wife told me to buy a new engine. So I bought a engine from TUFF DAWG ENGINE in AZ. A 350 440hp 450flbt. IT was 3000 free shipping to my door. I put it in and like I said early I was a dumbass and thought that a carb would be better. So i cut the wiring harness and end up doing alot more work. I rewirer the whole car. So I found a couple of tpi systems. There is one on here. The price is really good but the runner have some big dents. The other one is really nice but is going to be a lot more. But it comes with everything. The one on here come with almost everything. So I think I will end up buying the other one. Do you know where I can find the wiring harness for the inside of the car. Plus I need a stock gauge assembly. Right now I have the stock t-5 tranny in it and I put a rear end out of a 4th gen friebird that my friend had. He put 3.73 in it. I have not drove this car in a long time. The only thing I do is start it every week for about five to ten mins. I am so ready to put them horse on the ground. Anyway i am running at the mouth so I just want to say thanks for all your help. And this has been the best website I found on third gen Camaro. KEEP IT UP!!!!!!

No problem at all m8, im quite new the the community myself- they all have been greatly helpfull to me.

I swapped a 4.3 V6 with a 383 stroker TPI into a 00' S10. www.FuelInjection.com did both my harness and ECU for the swap, and made everything plug and play like it were directly from GM. My harness/ecu was quite expensive because it was custom, but you can give them an email to see what they want. Also, check out www.eficonnection.com.. im not familiar with them but i know they do the ecm/harness's for f-body's.

To keep things simple, i would look around for a MegaSquirt ECM/Harness ready to go.. Didnt you say you cut the harness? you still have the original ECM?

If you do have the ECM and only need the harness you will save alot of money. Sense you have a 91 im pretty sure thats the year they switched to OBD-II so you are going to have to find a harness for a 91-92 f-body.

So heres what you need to be exact:
85-86 F-Body TPI system (or just base plate for 85-86, with later guts)
91-92 Complete Harness
91-92 MAF sensor
91-92 Distributor/Cap

John

 

OK
So i just got off the phone with www.FuelInjection.com. He told me first I am going to need to get a different cam. The reason is my cam will not pull in enough vaccum. But thats nothing. But then he said since my engine is a high performance engine and they are having trouble with thier chips. he said to go with a after market computer and harness. THey would be able to store a close chip set in the after market computer but I will still need to take it somewhere to get it tuned. Anyway any help.

Scotty

 

I replied to the other post for your heads again, sense you dont have the center bolt heads, you will need to find the tpi baseplate for an 85-86 to fit. I would recomend crane cams 104224, its what im running. Do some research on a MegaSquirt system, or just ebay after ecm and harness for f-body

John

 

The person I spoke with at Fuel Injection Specialties said that he could get me a cam with the same specs as the one I got but with a different cam lob seperation. But my cam spec is 280/230 .512 valve lift. DO you know where I can get my ecm programmed at.

 

Let me get a few more details from you.

When you originally bought the car, did it have TPI?
If so, Do you still have the stock ECM in the car for it?

A very popular mild TPI cam is CraneCams 104224. I run it myself, and i know a few others in the community do. Check it out.

 

No it was a 305 tbi. But I do have the stock ecm.

 

Well the reason fuelinjection.com cant do anything for you is because they are strictly OBD-II, if you wanted to go threw them.. you would basically have to do what i did.. build a vortec 350, with older heads and TPI sitting on it.

Sense it was TBI, i wouldent get into the mess of having someone re programing your current ECM for TPI, try eficonnection.com, see what they have to say.. they close in an hour so hurry.

Also, get on ebay and search Camaro ECM Harness and see what you can find.. there quite pricey new, sense it sounds like your going with a stock setup you wont 'need' after market tuning.

John

 

Oh, and dont forget to check this cam out, it should be perfect for your application:

John

 

My engine is not stock. Go here and this is my engine http://www.tuffdawgengines.com/chev_350_440hp.htm

 

Ah okay, well let me do some math and figure out a good cam for your setup.. also remembering that you have all them horses, you will need to stick with atleast 24lb injectors, otherwise TPI might be a loss for you.. another thing to find on ebay. Remember ford injectors!

Call eficonnection, see what they can put togehter for your ecm/harness. ill find you a cam.

 

So i found this whole seup on ebay for sale. It comes with the wiring and everything. Why is it that i need a newer wiring harness. I am waiting on the guy to email me with the year the whole system cam off.
----------
If i could get on ebay at work i would give you a link.So when I get home i will give you a link. But this setup comes with new ford injectors aswell.

 

I left a message we will have to see when they call me. But the setup that I am buying comes with the ecm and wiring along with the maf and intake runners all of it. So if I am understanding all I will have to do is get the ecm programed for my engine.

 

Okay, found a COMP Cams cam for you, you are loosing .2 lift on both intake and ex, but its the only thing i can find close for your engine that is computer compatible, and hydraulic roller.

http://store.summitracing.com/partde...8&autoview=sku

That cam should keep you in the same range your currently in.. and wont give the computer hell.

 

And a new cam because of the lobe seperation is 110.

 

If you just want to go with a stock cam like the rest of us you can do that, but yes your going to have to get your ECM programmed for the cam you swap to otherwise your going to have timing issues.

CraneCams 104224 is the biggest aftermarket that you dont need to mod your ecm for.

The cam i listed from comp, will give you about the same lift and such so your not 'loosing' what you originally had. But EFIConnection should be able to do the the programming for that cam.

John
----------
The lobe sep on that comp is 114, mine is 112. Shouldent have any problems.

 

Cool hopefully I will win this setup on ebay and then get that on order. I was reading up on here about radiators and some people say that the stock one will work up to 500hp. I am having problems with over heating. What is your take on that.

 

if your using the stock radiator from the 305, im pretty sure its the same core as the 4.3 v6. call your local scrap yard and find a radiator for Z that had a 350.
----------
another thing you might want to do to get some advice on where to get your ECM tuned, post in the ECM forum stating that you are putting a TPI on your 350 and need to get the ECM tuned for your bore and cam, a few people should be able to refer you to some mail-in company's that are cheap.

May i see the TPI setup you are bidding on ebay, ill aware you that it is for an 85-86 to fit your heads

John

 

OK my wife called me and told me the setup that I was looking at is off a 1988. So that will not work

 

Ok so I called back the people from FUEL INJECTION SPECIALTIES and he told me to get this cam CCA-12-366-4.

 

Correct, you need one for an 85-86 to fit your heads.

Still, if you can get it cheap.. get it then find a baseplate for an 85-86.

 

http://store.summitracing.com/partde...4&autoview=sku

That is a flat tappet cam, you need a hydraulic roller cam. The page you sent me about your engine says its a roller block. The cam i sent you before is a roller cam.

 

New Hydraulic flat tappet cam with .512" valve lift


This is the one I am looking at.
http://cgi.ebay.com/ebaymotors/5-7-T...spagenameZWDVW

 

Here is the setup you would need:

http://cgi.ebay.com/ebaymotors/86-ir...ayphotohosting

You would just then need a ecu and harness. Also just noticed that your engine is a hydraulic tappet, sorry about that. The cam the guy showed you will be good for your setup.

Or, if you can win the one your bidding on, also try to win this and just swap the base plates:

http://cgi.ebay.com/ebaymotors/TPI-C...QQcmdZViewItem

John

 

Thats what i would try to do, get the one your bidding on, and get that base plate i listed. Swap the base plates, and boom your good to go.

Then all you will have to do is get your ECM programmed, like i said.. post on the ECM forum here on thirdgen and see if anyone has advice on where to go for the programming.

 

What about that cam.

 

Now that i noticed that your block is a hydraulic tappet, The cam the guy showed you will be good for your setup.

http://store.summitracing.com/partde...4&autoview=sku

Try your hardest to get the TPI setup your bidding on, and the base plate i showed you:

http://cgi.ebay.com/ebaymotors/TPI-C...QQcmdZViewItem

 

OBDII started in 96. 90-92 did not have a MAF they were MAP, and a small cap distributer with an external coil is interchangeable with all years that had them (87+).
