June 12, 2009hey im pretty new to toyota but they have been in my family for a long time... i need help with somthings and hope sombody can help my 22r blew up on me so i bought a 22re and im hoping to put it in my truck .. but i want to convert it over to carb because i dont want to spend all the time to figure out the wiring harnesses .. my question is what all will i need to change it over to carb.. the engine was rebuilt with everything redone.. so i know its a good motor but what will i need buy *or* do it to make a carb system work? and will my transmisson bolt up to the bell housing?
June 13, 2009Well, since you are needing a lot less of the wiring involved it should be as simple as taping off all the unused portion of the harness that ran to the fuel injection system. If you later need power to something just untape and put a volt meter on wire ends until you find one that is hot when you need it to be. Retape harness when you find what you need and just keep it intack as much as possible. Maybe someday down the road you might sell the truck and the next person will want to reverse back to a 22re set up. most manufacterers, like Toyota, change the harness from year to year. So it makes it a bit more difficult to know exactly what to keep and what to tape off when there are often different ways to look at what you might be trying to do. Unless someone on here has the year and accessories you have and are changing to.
June 13, 2009cant i just take off all the fuel injection crap and put on and intake system and a carb... i know that i will need some wiring.. is it just a matter finding which ones ill need.. *or* what?
June 13, 2009I am thinking it should be that easy. If head gaskets are the same for both engines, then yes. Ask a parts counter guy to bring both gaskets out for you to look at. If the locations match and the size of the ports are the same. Then there should not be any problems in the conversion as far as bolting up the manifolds.
June 13, 2009kk well do you know much about like versatility between engines... like the engine is from an 85 *or* 84.. and my truck is an 83 so as far as being interchangable for like mounts and stuff.. *or* even from my transmission .. i guess when i get the new engine pulled out of the truck ill find out if the manifold pattern will fit *or* now.. *or* the intake sstem.. but like will i have to use the alternator.. outa the new one *or* still use my old one.. and with like vacum lines...? and do you have any preferances as to what brand of intake/ carb system i should use.. like weber *or* edlbrock.. cause if im going to do this.. im gunna do it right and get all the power i can outa it
June 13, 2009GOOD FOR YOU! Yours is a great attitude to have. I have done conversions and like the parts companies you mentioned. When it comes to fuel components it is critical to get it right on the mark the first time. If not the installer can have some time involved and head scratching trying to figure out what went wrong. My personal choice is often to put a OEM (Original Equipment of Manufacterer) part on if it fits. Like all mechanics, I too, hate to do things twice. Liked your thoughts on seeing what the transmission pattern is like when you see it in person. Take some good measurements and then you will know for sure if the engines are the same. I am thinking they are. But always better to double check first. I havce not done what you are thinking of doing. It has been done the other way by people I know. They took out a 22r and put in a 22re. So I am thinking you should not have any big problems.
June 13, 2009ok so you would advise me to try and put on the original intake system first, to see if it works.. and if it does would ou put on a performans one? cause i still want to get all the power i can outa it.. but im jusst hoping it all works out.. im prety sure that the between the 22r to the 22re the block stayed the samme so the bellhouseing olt patternt should stay the sxame.. i had an 87 pickup that had a 22r in it but the transmission wanst the same as the one i had in m truck.. but it was still a 22r and i got alot of parts off that engine that fit my engine..the transmission in the 87 was alot longewr then the one i had in mytn and the new engine has that same transmission as the 87 bolted to it.. so if my thinking is correct.. the block stayed the same .. and my transmission should bolt up with my new engine!.. i hope
June 13, 2009When the length of an engine and transmission are longer **or** shorter than what was stock can often mean the driveshaft will need to be modified. If you have the one from the ''''87 it should bolt right into the truck you are adding the tranny to. Do take a little time to think it all through before you jump in. I was not a big note taker. But have known people that are. It helped them stay ahead of any problems they might face whan in a changeover. if you are wanting aftermarket extra performance from another carb. maker I do not feel comfortable giving you advice on that. I am not a fully into Toyota stuff type of person either. My truck is not even powered by a Toyota. This kind of choice has to be to your liking not mine.
June 13, 2009well see the new enginew i bought i bought the whole thing, its a 4 runner and the trann went out on it.. and i dont have the 87 anymore i sold it awhile back.. so i have my transmission and thats it.. i will agree with you that making sure of everthing is the key to making my project easy..when i found this site i was extremly happy. because i knew i could get some insite as to how to do things.. from peopke with more experiance then me
June 15, 2009hey so i checked and the gaskets are exactly the same.. smae bold pattern and all.. what else would ou recommend me checking?
June 16, 2009Well, a lot of little things. Besides the shape and pattern of the transmissiion you are going to install. Look closely to the splines on the input shaft. Check for ware on splines. They should not show any, **or** be narroewed in some places and without ware on the places where the clutch disc is not riding. If ware is noticable take the clutch apart and replace if ware looks pretty deep into the rivits that hold the disc together. Also check the operation of the throw-out bearing. If it is not smooth while turning *or* makes a noise it is better to just replace it now. Remove the gear fluid out of tranny before assembly. Once the tranny is bolted in and all the other components are bolted to it, with vehicle on flat ground fill tranny up. This will let you know right away if you forgot something important. Like a seal *or* bolt someplace. Take some good measurments for the rear driveshaft. Might get lucky and the one that would be on the back of tranny in a truck like yours will fit. Can save a lot of money if a used one will work in place of buying a newshaft. Use bolts and nuts made for the briveshaft. They have to be stronger than normal nuts and bolts to stay working on driveline. The torque reading us usually a lot higher. Before bolting in the driveshaft check for the factory torque settings on the transmission output nut and the companion flange nut on front of differential. This can be an area of vibrations if either of these nuts are loose **or** become loose. Well, those are some of my thoughts on the transmission. Are you set on the install of the carburator and manifold? Your service manual should tell you step by step on how to do that. Follow the instructions carefully. One very important thing to remember when installing a fuel delivery system. Everything must be clean. Just the smallest piece of dirt in a close tolerance, machined surface can cause it to leak vaccum, air *or* fuel. So keep it all clean and assemble on a clean workbench. Even your hand tools shouls be free of any dirt before you start. With clean hands feel for burrs, scrapes, *or* other inperfections while each piece is assembled. Even a small piece of tape *or* thread locking gel can effect a surface if it leekes onto a place it should not be. If this is a first time then go slow and double check each stage as you assemble.
