    I have 1987 LX 5.0 hatchback and 1991 GT convertible. Both are stock* - 87 has speed density, 91 has maf. Will BBK 70 mm throttle body w/EGR spacer be compatible and beneficial with otherwise stock engines*? Any other cost effective improvements? *stock EXCEPT Flowmaster mufflers, K&N filters, 3.55 gears on 87,

    • Yes the BBK 70mm Throttle body and EGR spacer will give you performance gains on a mostly stock car.

    With throttle body is bigger the70 or the75 and can I bolt it on a stock 5.0

    • Hey Chris, The 75 is larger given that it is 75mm and the other is only 70mm. So the bore is 5 mm bigger. As for a stock 5.0 the 70mm is better for a stock application, the 75 is more for force inducted motors (i.e. superchargers and turbochargers)

      Amazing product, issues with idle/running

      I have a 1992 Fox with a built 5.0, roller rockers, pistons, cold air intake, smog pump delete, headers and exhaust back... ect. Fun installation and job. Did it myself with minor issues. Would recommend doing spark plugs when you do this too. Had an issue with running at idle and when throttle is applied, it would sometimes die out when it de-accelerated. Taking it to a shop to figure that out. Check engine light came on with it too but regardless it drove well. Opens up the sound, intake, performance, and you can even hear a little whistle of air coming in.

      Easy install

      Install went smoothly without any issues. The quality of these parts are superb to anything out there and they're American made so that's a plus. Not sure if it's just my car but at initial startup and idle if was rough, stalling, pegging, surging, until the computer finally adjusted after around 15 minutes. Double checked for leaks at the egr spacer and nothing so overall I'm very pleased with this addition to the car.

      This made the difference in my 5.0. I already had a cold air intake and new BBK headers. Running the stock throttle body really didn’t do much but put this on and I can honestly say is the #1 greatest upgrade I’ve made that I’ve seen the most amount of horsepower from. Wasn’t hard to install, but setting idle was tricky. Awesome!!

      Good additional performance upgrade

      The good part: the difference in the way it sounds and performs is night and day over the stock throttle body and egr spacer but, Now the bad part: i could never get it to idle correctly. come to find out when i took the BBK TB off anitfreeze was leaking into the TB and being suck into the intake. I have tried 3 times to try and get the egr spacer to seal up with the throttle body no luck. No problem with the stock unit which is what is on the car now. If i wasnt having a problem with it leaking I would have given it a 5 star. will try again in spring

      Best Bolt-On so far!

      This Throttle Body and EGR Spacer gave me more increase in performance than any other bolt on I've had. Most people get new intake manifolds to match 70mm but I highly recommend that you just port match the intake manifold. Should cost $100 or less for port match and installation. Highly recommend this product!

      BBK throttle body

      Performance is much better than stock throttle body, be sure to reset your tps sensor voltage. Also, If you have an automatic the bushing on the linkage that came from BBK is not the right size as it is too small for the tv cable to snap into. Ditch that bushing and go with an oem one an you will be good to go. Other than that it is a nice performance piece, go with it.

      Great Product!

      Paired this with a 70mm Mass Air, 70mm EGR spacer, and a Typhoon Intake with a 70mm opening. Sounds great when punching the gas. Throttle response also feels much better. Over all a great product.

      More Power

      The throttle body was very easy to put on once we got the old one off! Twenty some years of rust and corrosion made it very difficult and time consuming to get the old one off. Once the BBK was in place, the only other issue was the grommet on the TV line. The new one did not fit the old line connection. We tried drilling the grommet out, but ended up popping the new grommet out and putting the old one in its place. So far so good! The throttle response is great, much more giddy up in her now!
