mobythevan Posted May 16, 2005 Share Posted May 16, 2005 Man does it run good. I am impressed. Starts fast, idles really smooth. Throttle response and acceleration are amazing. This is regular old sbc with an 87 TPI setup on it and mild performance build. MSnS_Extra controlling fuel and spark through original small cap TPI distributor with 8 pin HEI module. Thinking about putting TPI in your z? Go for it and throw away the GM ECU so you can use MSnS_Extra. Quote Link to comment Share on other sites More sharing options...

patzky1 Posted May 16, 2005 Share Posted May 16, 2005 What did that cost you and what exact parts did you use? I'm getting tired of my carby and thinking that TPI fwould be easy enough to do similarly to yours since I have a 77. Pat Quote Link to comment Share on other sites More sharing options...
mobythevan Posted May 16, 2005 Author Share Posted May 16, 2005 It broke down something like this: 87 TPI -- $300 (with distributor/coil/fuel rails/harness/etc) megasquirt -- $180 TPI air filter -- $30 EFI fuel pump -- $100 Around $600 depending on what the TPI setup will cost you. Seems like I am forgetting something. Ask if there is something obvious missing from that list. We hacked up the harness to re-use it with megasquirt. A couple side notes, we had to machine the four center bolts because 87 TPI manifold center bolts don't fit old style sbc heads. Easy enough to grind/re-drill them. Checkers sells a thermostat neck for TPI. This was missing on the one we bought. Try to get the throttle cable ad water kneck when you buy a setup.

tannji Posted May 16, 2005 Share Posted May 16, 2005 I currently run TPI in my 240.... what gains could I expect stock, and/or what would I be looking at to get some gains out of my relatively tame 350 setup with the MS ECU? Quote Link to comment Share on other sites More sharing options...
wheelman Posted May 16, 2005 Share Posted May 16, 2005 Is $250.00 a good price for a TPI setup? A guy I know locally is selling all the intake parts forward of the firewall as a package. The setup includes the following: Upper and lower manifolds Runners Fuel rails Injectors Distributor Coil HEI or ISE module? ECU All sensors Wiring harness Custom programmed chip for high performance 350 Air filter intake tract from the filter box(es) back He says it uses a MAF sensor but I'm not sure about that, when I started to try to get more info regarding this aspect of it he seemed to get his terms confused. Maybe I'm wrong but I thought those systems were speed density. He also said it came from an 89 IROC Z28 Camaro. Wheelman Quote Link to comment Share on other sites More sharing options...
mobythevan Posted May 16, 2005 Author Share Posted May 16, 2005 wheelman, that sounds like a good price for everything. Another thing to watch out for is injector size because most of the TPI units are off 305 engines. tannji, megasquirt shouldn't give you much gain over the stock ECU. But it gives you flexibilty to tune yourself and add any upgrades you want. Like nitrous, turbo, bigger injectors and re-tune fuel and spark more easily than the stock ECU. The plan with this setup is to add 2 280zx stock T3 turbos this winter and run 8-10 psi. Quote Link to comment Share on other sites More sharing options...
Tony D Posted May 18, 2005 Share Posted May 18, 2005 One thing to remember about going V8, injector soucres from import engines easily make big power potential. Most V8's only run around a 24# injector... Low specific output per cylinder. Most import units are that big, if not bigger. Supra 440cc, hell Ford TBI is almost 500! That's serious fuel flow potential! I have had TPI on my mind for a project, but for some reason the obvious application of the MS to it totally never came into mind... I guess I flake from time to time, eh? Quote Link to comment Share on other sites More sharing options...
randy 77zt Posted May 18, 2005 Share Posted May 18, 2005 if you like fancy high dollar stuff for tpi you can get high flow runners from arizona speed&marine.throttle cables specific for tpi from lokar.i get lokar part# from thier website then order from summit.tpi unit makes good low/mid torque-just the thing in a z with good hook up.there is a guy on ebay that sell injectors cheap.the 350 engines had 24lbs.the 305s had 19s.30s and 42 are easy to get.

Guest 73Turbo240z Posted June 8, 2005 Share Posted June 8, 2005 mind sharing a small install writeup on this? i have a 305 TPI motor in my volvo, and the stock harness is all buggered up (was done by the P.O.), i have a complete 305 TPI in it, and i have a complete MSnS sitting on the parts shelf... sounds like somthing that with a decent write up i could knock out in a day, currently the car runs like ***...

mobythevan Posted June 8, 2005 Author Share Posted June 8, 2005 I could probably put something together. It is an easier install than the 280zx turbo I think. If I have time today I'll put up a small writeup. Quote Link to comment Share on other sites More sharing options...

If I have time today I'll put up a small writeup. if you've got a digital camera and want to just shoot photos of all the places you tapped into, label em up, then upload your photos and tune files... should be pretty simple. do you know off hand if the 305 is super picky about heating? were noticing a correlation of if it gets around 200+ degrees on the water temp it starts running like ***... since this is in a volvo we can't tell if its a normal camaro issue, or if were overheating since its in a volvo engine bay.

mobythevan Posted June 8, 2005 Author Share Posted June 8, 2005 Nothing was tapped into for wiring. We had the TPI manifold on the car and megasquirt on the side and built a complete wiring harness from every sensor/injector to the megasquirt. So if your looking for a wiring diagram from original harness to megasquirt I can't help. I'll put up the info and see if its any help to anyone, but it might not be.
