I read some other threads but could not find exactly what i was looking for. I have an 85 Z28 with a 305 TPI, 700R4 trans. I am looking to drop in a blueprint 383 crate motor from summit. I am going to keep it fuel injected and need to know what i need to do to keep it fuel injected and have the TPi work. What size injectors you guys used? type of throttle body used? Manifold used? I cannot afford these ram jet kits and stuff. i need to get it to work as cheap but right as i can. Do i need a new chip? whats involved in the tuning the new motor will need? do i need new flex plate? I am trying to put a parts list together so i can get everything i need and any help would be greatly appreciated.

I wouldn't use the 85, 1226870 upgrade to the 1227165. The baud rate , code of the 870 ECM isn't that great. For a 430 hp engine you will need 32#hr or could use 36#hr injectors.A Hsr or knock off on eBay would allow the 383 to breath fairly well.

 

Thanks for info, that helps alot.

 

np contact member southbay08 for your injectors. If you mention Tuned you can save 10%

 

i am having a ton of problems trying to find a mass airflow meter to go with the 36lb injectors i have. even summit had no answer.

 

Use your stock max and have your ecm tuned. You will need to buy some equipment like a Aldo to USB cable and use tunerpro rt or tts data master to capture data.

 

The ECMs dont come with chips, so what should i do about a new chip?

 

Post a wanted add in the classifieds, look on eBay, I have a few and would sell you one, tpiparts.net has them.

 

Hopefully not hijacking thread. just looking for more info on this...
Do you know what years this 1227165 came in? I have an '89

Capture data to send to someone to mail order tune it?....or is there a way to tune it myself. I have TTS and also TunerCat for LT1 I used to have. I'm new to TGO as you can tell.

 

bump this back up please...
