I was thinking about installing a Weber 32/36 carb and want to know what others think about adding a new intake manifold that matches the carb. Its a 1987 4x4 that already runs good but I would like to improve milage and performance if possible. Already installed larger exhaust which helped but I have alittle more money to do at least a little more. Tell me what you think. Also opinions about getting the carg with manual or automatic choke from those that have already installed them.
if you got the coin, offenhauser intake manifolds are pretty sweet. if you are going for power though i would get a 38/38 instead of a 32/36. I have a 32/36 but thats cause i wanted fuel economy and a little oompf when i floor it. http://cgi.ebay.com/ebaymotors/Toyo...ptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories
thats what I heard but trying to figure out which manifold is the right one is giving me some problems. Did the Weber give you better milage then the orginal and have you had any problem with the choke or is it manual?
The Offenhauser dual port intakes work best on a stock engine, the divided intake runners reduce the port size which gives a little crisper throttle response off idle, but run outa breath at upper RPM's. The Offy "C" series intakes are better suited to mid and upper RPM use as they don't have a divided runner. You'll get better economy and a slight gain in power with the 32/36, the 38mm is better suited for modified engines but fuel economy will suffer. The electric choke models work fine and are pretty reliable if adjusted correctly, the manual choke is fine too, pretty idiot proof.
Is that a camper? Thanks for the info on the manifold. My main goal is to get better fuel economy which sounds like from what you said the divided intake would be okay since the truck will be in 5th gear going down the highway and low RPM's. Am I correct in this thinking? Also wanted to know if thats a camper on the truck in the picture and did you fabricate it? It looks sweet.
i got better mileage with my weber, but i also stepped up to a 5 speed trans and a 3.07 rear end all at the same time. It was a stock 73 that I blew the motor on so i swapped in a 22r and a w58 and the rear diff swap all at the same time. i get 28-30, but i also dropped my tire size a little when i lowered it to help get some of my gearing back. if i was running a taller tire i think my mileage would suffer cause it would take more throttle on the freeway to keep up speed cause of the wind resistance
For a daily driver the dual port Offy intake should work fine for you. Yes thats a camper in the picture, They were originally built by Chinook, I bought this one about 23 years ago in junkyard condition and did a frame up restro with many additions from stock plus added the 4wd drivetrain. Heres a few pictures I posted for another member of it and my other one, Thanks. http://www.toyotaminis.com/forum/off-topic-12/dudevato-few-pix-4-ya-8695/
38 is way overkill for anything close to stock, my truck had one when I got it, Drove like I had an egg under the gas pedal and BARELY got 13 mpg. Picked up an Empi since Weber was on strike at the time, jumped to 18-19mpg around town, even got 25 on the trip to La Pine with Super Swamper tires . The 38 are meant as a replacement for the straight 6 yotas like in the old FJ40s. the 32/36 gets better mpg because for the most part you are only running on the 32, then when you get on it the 36 opens up too. With the 38 both sides open at the same time.
Nice work on the camper Thanks for the advice-going with the dual port offy and Weber 32/36. I'll have to keep staying in the tent thou to keep the cost of the fish down as the spouse still isn't convinced catching your own is cheaper than buying them.
