240Z-DET Posted September 24, 2002 Share Posted September 24, 2002 considered converting a carb'd small block to EFI using the factory TPI retrofitted to the GEN I heads? I saw the website LT1intake.com and thought about a hybrid system. Let me know if this would work. I want to install the LT1 intake but use the TPI harness with ECM and all sensors. I purchased a 350 instead of the DET, and am gathering all the necessary info and parts. I have the basic JTR manual and read it inside out, but I need to order the one on EFI. Any input would greatly be appreciated. Thanks. Rob Quote Link to comment Share on other sites More sharing options...
Mike C Posted September 24, 2002 Share Posted September 24, 2002 If you have the L98 TPI parts, may be easiest to just buy the Holley Stealth ram. After acquiring an LT1 intake and having it modified for cooling and distributor you'll be about even, but done already. Quote Link to comment Share on other sites More sharing options...
240Z-DET Posted September 24, 2002 Author Share Posted September 24, 2002 Thanks Mike. Another question. Has anyone successfully switched the speed density to mass flow in the TPI? Is it even feasible/worthwhile to do? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Mike C Posted September 24, 2002 Share Posted September 24, 2002 The '85-'89? TPI engines are MAF while the 90-92 are speed density. This is obviously easy as you can use all GM parts. The 85-86 manifolds are for old style cylinder heads, while the 87 and up are for the new style cylinder heads (but not Vortecs) Scoggin Dickey has a Vortec TPI intake.
