hey guys looking for a little advice on my planning of my 87 lx fox project. revisitng the car after a half ass restore/ build 12 years ago when i was a broke college kid. im looking to add a vortech blower to my car, i always wanted too and the previous owner built the motor to handle 12 lbs of boost and his intention was to add the charger. fast forward now im getting to repaint and restore and hopefully after add the charger. im leaning towards the vortech v3 si kit from anderson ford motorpsort. my goal is 450 hp to stay safe within the stock blocks specs. i have tfs heads, cam, gt40 tubular intake, rockers, forge pistons arp hardware etc. i currently have 30lb injectors and a set of 42 on the shelf car is not raced and is driven weekly on nice days in the summer. i see different stages of kits my first question is
1. is it overkill for me to get the holley terminator x system for my car. or do i stick with the msd btm setup. or do i do a chip and tune on stock ecu the car will never be raced and i dont see ever pushing it past the stock block limits. my car does some weird idling stuff occassionally already...
2. is it worth to buy the advance kits from anderson or simply buy the low end kit and purchase my own walboro 255lph pump, aeromtive fuel regulator etc.
3.) id like to keep the stock fan setup can this be run with this blower> ive seen some youtube videos and people run it not a big fan of electrical fans and currently my car stays cool just fine.
4.) are 42lb injectors enough for my goal or do i need larger?

i appreciate any feedback that is offered thanks!

In the garage
V3
Anderson power pipe
42 or 60 # imjectors
340 Wahlbro fuel pump
Ed Curtis or Anderson B41 cam
COmetic head gaskets
ARP head studs
Kirban Adjustable FPR
Boost, Fuel and AFR gauges
Ford Racing or Pioneer Balancer
Contour Dual FAns and good Radiator- Champion, Griffien,, Be Cool
I would go with a PRO M MAF or SCT at least 80MM
70 MM is plenty
You only need an MSD if you get spark blow out, the stock Coil and ignition system is very good and will carry you well into 500hp

Up to you if you eant to go Holley . I have owned several supercharged Fox Body cars using stock A9L/A9P with an SCT piggy back chip tuned by Thinder Autosports, but there re several good tuners you can work with and your a9;/a9p- leech motorsports, Dirty Diry Racing , Decipha

Thanks for the reply. I plan on getting the kit with the power pipe and upgrading my fuel system. Idk how much I trust my old ECU so that was my thought if I'm gonna spend 600 on a new computer and chip maybe just go the extra mile and get the Holley. I have a stock dizzy and upgraded coil. My heads r supposedly o ringed?already have arp studs That's what the paper says I got from the guy when I bought the car. Didn't really wanna pull heads off if I don't have to. Motor has maybe 20 k on it. But I have to redo my intake gasket and one bolt hole had messed up threads so I may have to take the head off anyways to get it fixed at a machine shop.

Personally, I'd ditch the stock ECU. Newer technology is so much more versatile and user friendly. You can ditch the mass air then too.

255 Walbro pump
47lb Ford injectors
Air to air intercooler
Tial blow off valve

Vortech V3 H.O. Kit
47lb injectors
340 lph Walbro
Stock ECU with a custom tune

Edelbrock Performer heads
Ford Racing B cam
Cobra upper intake

Stock original 5.0 block

Car made 426hp at tires, which is just at 500hp at crank. That is the number you should try to limit your build to as I hear that is about what the stock block can take.

Would 42lb injectors get me to 475 500 crank hp? I most likely will go the Holley terminator route. I already have 42. But I can buy 60s if needed. And I plan on doing the 255lph hi pressure pump.

Sparky and @a91what, why would someone want to ditch MAF to go with speed density?
My understanding that might need updated - I figure the speed density will run great under the conditions it is programmed for. But the meter (MAF) should work well from a cold day in Death Valley to the top of Pike’s Peak

@87fox72mach The ECU exchange has been on eBay for quite a while, and their service is great. The actual username is bmwsalepro
Even with an electronics background, (I have repaired keyboards, amps, etc), I will still send a stock computer in for service AND a test instead of just replacing the caps and giving it a visual inspection on my own. At this point, it’s preventative maintenance, like the caps in a tube type amp or radio.

MAF units do work well if you are running NA. However they cannot see boost levels, you can have the same mass flow at a different density and need other fuel requirements.
The vast majority of oem now tune speed density and have moved away from maf.

I have had very good luck with maf installs as long as they are setup as pull through.
MS is a very flexible platform, you can tune maf with a stock unit or if it hits the wall you can easily transfer over to speed density.
I like to use the 90mm Lmaf they are good to around 450hp and have great resolution.

I have no issue driving my SD tuned 393w with twin turbo in any weather condition and baro does not effect a tune as much as you think it does unless your running pikes peak. I simply run a method called %baro and using a datalog or 2 setup the baro correction curve.

I've driven my MS speed density tuned car at temps below freezing to over 100 degrees and several thousands of feet in elevation change without a hiccup. I can run open breathers and open atmosphere blow off valve without unmetered air throwing off my tune. I can change injector sizes when I decide to throw more power at this setup without having to re calibrate or changing a MAF sensor. Dumping the stock ECU and MAF is the best upgrade I've made.

I will add my vote for ms based ecu. I’m running speed density with no issues.
