Whats the best OE system to use? And which harness would make it easier to adapt to a maverick one? Its going onto a built 5.0L and i wanna tune it also with Tweezer. I will be using a GT40 tubular intake.
tweecer is a really picky tuning software... take a look at a few others before you make a purchase... as for harnesses get a MAF harness... i know some people prefer to use an auto harness even if they are going five speed... your choice though... i suggest a plug and play aftermarket harness... your time digging through wires and diagrams is worth more than you might think good luck with the swap
Im not really into the plug and play or preburned chip redneck type of tuning. I mean it was fine back in the early 90s but in this day and age i want something that will let me controll all variables. Down to the pulse width. Im comfortable with wiring so thats not an issue. Thanks for the info guys. Really appreciate it. Also if anyone can recommend a better tuning software id like to hear about it.
this is how i plan on switching to efi. use a stock efi harness from a fox mustang. use the 5.0 microsquirt kit from this company http://www.efisource.com/products.php?category=2 get a ford explorer intake assembly or use a vic jr with fuel inectors depending on funds. i have a mallory efi pump already. there are endless pump options so you can figure that out for your self. the microsquirt is a megasquirt2 built extra compact.
I have often thought of EFI for my Comet GT and I have a complete set up from a 93 mustang gt, including the complete wiring harness. But I think the Ford set up is the must butt ugly system out there. On the other hand, and I hate to say it, but the chevy tpi is a sweet looking set up. I've often wondered if there is a way to mate the tpi manifold to the 302 and accept the Ford throttle body and injectors. Or maybe just use a standard aluminum 302 manifold and adapt it to use all the Ford components. Any of you FI gurus have any ideas?
what i meant by plug and play is that companies like painless and even ford racing have harnesses that you can purchase that only need hot in run and start signals to hook up... still uses factory ford eecs and keeps the same tunability... as opposed to spending a week trying to fish through a spaghetti plate of wires and most of them being useless... as far as tuning software goes if youre sticking with a ford eec then binary editor and eec analyzer, or cal edit and cal con are a couple good choices.... if you wanna start from scratch... you can do like bryant suggested and get a megasquirt system... i think they even sell start-from-scratch harnesses so you can loom it up exactly how you want...
it would be very hard to adapt the tpi intake to a ford. 1st problem the sbc inake ports are ran in pairs if that makes sence. where ford is evenly spaced 2nd is the distributor of the ford would hit the the throttle body on the tpi set up. best way to get a similar look is to switch to a distributorless system. the explorer uses one and has a cam sensor that goes into the distributor hole wich would give clearance to a front mount throttlebody. then you could build a sheet metal upper inakte manifold for a stock efi lower or you could use a tunnel ram intake with custom plenum.
Yea, I know how the runners are on a sbc tpi, but they are aluminum,. Was thinking one could cut them off at the upper end and fabricate runners to a ford intake. A lot of work plus the distributor issue. Why cant you take an PRM air gap manifold and weld bungs near the base to accept the injectors and make an adapter to bolt the throttle body where the carb usually goes?
you can ... have seen it done quite often... and make an adapter to accept a stock carb style air cleaner... sleeper
just went on edelbrocks website and they have quite a few different intake adapters in order to convert a 4bbl intake to accept a ford efi throttle body.... most are elbows though
This is what I just put on my Maverick. http://www.retrotekspeed.com/products/powerjection-iii/ I like the old school looks and it runs fantastic! It's still not cheap but not as much as the Edelbrock system.
