Phew... that was a long week.

Thanks SCott for picking up the motor.

Hepcat, you never called... I still have the mirrors if you need them.

Anthony, I took the A pillar pieces off and have them... call me when you can.

Everyone else, welcome back to TGO...

Rob

 

welcome back indeed... i'm glad Dirk was able to leave status updates on the site tho. If i just got one of those funky "page not found" thingys, i'd have gone nutz.

 

HELLO ALL!
I am down witha 3 week case of pnuemonia.
The last week has been rough, and no chatting to boot. UGH
Hope all is well.
Oh rob, did the box make it yet?
shawn

 

Ok cool thanks Rob. I'll give you a call hopefully soon. Man it's good to be back. I've been suffering thirdgen withdrawals lol

 

Shawn, box will go out this week.

been swamped at work and had to get a new watchdog for the house... did find a box for the console plate... so you should be getting three packages...

let me know when you get them...

 

Thanks for the engine, Rob.

I'm glad the site is back up because I've been waiting to do more research on TPI's.

Scott

 

No prob Scott, thanks for taking it off my hands... (I really needed the space...)

 

What info are you looking for? I've done a lot of data compiling on TPI, since both my cars run on them....

 

Ed, Scott's looking for swap info...

most importantly, the C100?? (12 pin I believe) connector that connects the ECU harness to the under-dash functions. ECU, Ground, Injector 1, Injector 2, crank signal, ALDL, etc.... (well, thats 6 of them...)

He needs the relative positions for an '87 5.0 TPI, and how to hook them up.

 

Both the 5.0 and 5.7 TPI systems are the same, except for injector flow.

I have all these diagrams in JPG format, plus hard-copy of the Chevy TPI Fuel Injection Swapper's Guide and the '87 and '92 GM Camaro factory service manuals.

Rather than congest the TGO server with probably redundant files, I can provide these directly via email and Scott is always welcome to browse my reference library for additional info that I can copy for him.

Guess he's ready to swap out the carb and join the rest of us TPI guys getting 20+ mpg in town with the AC on...

 

I think I got 22MPG with my ElCamino W/TPI/700R4... including lead foot... and the A/C NEVER turned off...

 

I'll probably take you up on that offer soon.

You guys and your rediculous mpg disgust me! That's even better than my 3.0 V6 maxima- and I'm sure 100x more fun.

Scott

 

Well, if you do wanna go TPI, I got some extra TPI stuff I can sell you for cheap, mostly geared towards MAF, but some parts could be used for SD. Got a MAF plennum (unported), xtra MAS, 165 ECM with MAF BIN, fuel rail, fuel hardline set, set of 8 22# injectors, full gasket set, Painless MAF harness conversion, TB for a MAF car, but thats about it. One of the runners is dented and the base has a hairline crack. But honestly man, if you're gonna go EFI, I'd skip the TPI and go straight to either a LT1 intake converted to fit or a HSR. It would require about the same ammount of work, and your setup will breate better above 5000rpm, gives you more potential.

 

lol, i think there's somethign wrong with my car, i aint gettin no 20+mpg...

 

Thanks, when I figure out the other half of what you said there, Shawn, I'll let you know. It's like you're speaking half english-half french there to me....

I'm hoping this will be a "budget" project for my truck, so I'm not worried about high-rpm anything. Low to mid range torque is perfect.

And since it's my truck, I doubt if it'll even get 20 mpg goin' downhill! 10-12 mpg will make my day.

Scott

 

I think the right foot has an effect on gas mileage...LOL

 

I just did my rear brakes (OEM crap, oh well) adn I've noticed a slight increase in my economy. I almost hit 21 on the last tank-up. I'll know early next week if that was a fluke or not. I don't run the A/C much, and I run with the windows down a lot of hte time. If I had t-tops, I'd have them off a LOT!

 

oh how true I have the same problem

 

hehe right foot... that is true, I bet it does, but I rarely stomp on it ever, makes the car go sideways n stuff... scary kind of but i finally got the hang of it. I drive the Z pretty easily.. no speeding, sudden acceleration etc. I suppose the poor fuel economy comes from living up st.louis heights, but thats one thing i cant change. The dude i bought the car from said that the TPS sensor was all fudged up, but he replaced it, set it at right voltage... dont know if this is a problem though hehe...

Also, the car has the dual cat setup, but the previous owner evidently removed both, and straight piped em both, adding a SLP cat back at the same time... could this be causing poor fuel economy, O2 sensor issues?

Well in anycase, im trying to get the 91z up to selling condition, i.e. paint etc.

 

Yep, this is a great conversion -- add a more radical cam and the combo moves the powerband higher for much more power and less low-end traction problems. Should cost $700-1,000.

Cheapest though, is the stock TPI, doable for less than $300.

 

sure.. IF you can find a TPI that cheap... Scott scored on his... came complete... engine, trans, ECU, harness, fuel pump and all lines...

 

Most of the eBay transactions for TPI are completed for $300-400, it's really popular for all SBCs, especially street rods 'cause it looks very cool.

In fact I have an extra complete 1986 TPI system with wiring harness available for the same price.

 

I sent you a PM.

 

I assume you are talking about the TPI intake and related components, not a complete engine/trans...

Found some locally for 150-200... but Scotts one came with perfect runners...

 

My car used to do that at half throttle from a stop. Sure is fun and it impresses (certain) people, but you really need to get some good tires bro! Unless you're makin' assloads of power, that shouldn't really happen with sticky tires.

It's sorta like goin' fast vs. lookin' fast. Both are pretty fun though!

Or, did you already get tires? I don't remember, I just hope you threw those warriors out a long time ago. 'Specially in the rain.

Hey Ed, ya' think I could make a copy of the TPI swappers guide? It's not a very long book is it?

Scott

 

It's 128 pages ... you might wanna look at the book and select pages, we can scan and PDF the ones you need.

 

I have a copy of that book n' Ben Watson's, Hot to Tune & Modify Chevrolet Fuel Injection & TPIS' Insider Hints books if you wanna borrow them...
The swappers guide is a pretty good book if you just want to learn about TPI specifically, while Ben Watson's book goes a lot more in depth as far as how each of the components work. He goes into the details of some basic electronic theory and applies them to the various sensors used in engines... how map sensors work, square waves from the dizzy and a better explanation of how things interact with each other. Half of the TPI Swappers guide is straight out of a Chilton's manual for trouble shooting SES codes.

 

Yeah, I've got the swapper's guide, and it's good for troubleshooting problems, but htat's about it. Some good information and theory, but I was hungry for more. I'll have to get the TPIS hint book sometime. Actually, now that I JUST MIGHT score on this TTA, I probably need to buy some 'Buford' tech books and start hitting up on turbo theory.

 

actually, i woudn't reccommend wasting u're money on the TPIS book. I mean, it's interesting to read once over, but as far as learning the specifics of fuel injection, Ben Watson's book is far better. The TPIS book is really a giant advertisement for their miniram intake manifold and their cams. It does have a lot of dyno comparisons though, so i suppose their claims are somewhat justified. Just keep in mind who's running the dyno and assembling the motor...

 

Is the TPI swappers guide the book sold by Jags That Run?...

I used that for a TPI swap I did some time ago into an S-10... I think I gave the guy the book though...
