My Turbo Diesel Build (evil laugh here :D)

the b2600 uses a different trans completely, but you could have probably used a b2600i trans with the 8 bolt g6 250mm flywheel and clutch, but might still have the same starter issue with placement.

yeah, I looked into that and it just seemed that the starter would have the same issues. Speaking about issues with starters and transmissions, I'm going to need to find a starter for the Bongo now, the stock B series starter will not fit, it's too small

I'm trying to find out if the starter from a B2600 will work for me or not. In all likely hood, it won't.

I was also reading one of K6's post, where a heavier crank pulley is necessary with heavier flywheels to keep vibrations down. The crank pulley that I have weighs a good 30 lbs easily (that is with the weight that bolts to the center, weight is removable), the flywheel for the bongo is in the neighborhood of about 50. Im sure that this was necessary for the stock bongo setup, but that's a minimum of 80lbs rotational weight directly bolted to the crank.

I'm pretty certain that the crank pulley is non-harmonic in the RF diesels. The crank pulley that came with the escort setup weighs about 5 lbs, that flywheel was at least 50 lbs as well. Now, with the bongo flywheel, that one is even heavier than the escort one was, and the crank pulley being a lot heavier too.

The flywheel that I'm going to be using (for a number of reasons, first of which will allow me to use readily available clutches and pressure plates) is the one from the Sportage. This one weighs in about 25-35lbs. Also contemplating using the bongo crank pulley without the weight in the center, which will still make the crank heavier than the one that came with the Escort.

ok thanks for the infor i might hit you up with that offer i have an extra trans laying around actually. I need to work out my current turbo build problems first though. How much would you be asking for the tranny stuff.

EmJay · #**334** (**permalink**) 05-17-2010, 07:06 PM

It'd be a cheap pickup, I'm sure that the delivery is going to be steep though. I may decide to try to use the contershaft in the future, I have no idea to be competely honest. I'm saving up for a bearing press for other projects, I may decide to tinker with a JY tranny. Time will tell when our projects finish up and it's time for the next one. Whomever is first lol. But if I'm 100% correct with my guess, the countershaft from the bongo combined with the main shaft from the stock trans should help with towing and initial launch, which is what the both of us are after

supposedly the f2 and the g6 starters are the same, i had a bunch of g6 ones but never compared one up to a f2 one. what makes it not fit, bolting issues, solenoid in the way, or tooth notch in the wrong place? what side was the escort starter on?

EmJay · #**336** (**permalink**) 05-17-2010, 11:52 PM

The bolt spacing is much bigger for the bongo bellhousing than it is for the B series trans. It is on the same side as the escort starter was, however the escort starter uses a different pattern (otherwise the person I got the trannie from would have used it for one of his projects as he has tons of escort parts.)

wow that really blows! i just hope once you get a bongo starter it fits with the kia flywheel teeth *fingers crossed for ya*

EmJay · #**338** (**permalink**) 05-18-2010, 08:15 AM

I don't think that I'm going to have a problem with that. The ring gear sits at the same point for all 3 flywheels. Granted, the escort flywheel is now gone (destroyed by incompetent machinist at Chix in Marietta, F*** you old man!) but I did lay it next to the FE flywheel and they were in same position. Same thing with the FE and Kia flywheel, and same thing with Bongo and Kia flywheel. I'm fine there

PearBear2k10 · #**339** (**permalink**) 05-18-2010, 08:53 AM

If it has differnet teeth could you change the starter gear just and idea dont know if it work. Yeah im always up for new ideas and trying stuff even if it might not work lol. and yeah im gonna need alot of help on initial launch

. I might be down your way later in the year depending on what we do for vacation i could prolly pick it up then that would eliminate shipping.

Well Perry you might hate me on this one, I finally got the gear box down to the bearing plate and I noticed quite a few things on this trans that I'm really starting to like a lot. First off, I noticed that reverse has a brass synchro ring whereas on the stock B trannies there isn't one (this is the 3rd one I've had apart in my hands.) In addition, if 5th gear does swap over, I think that I'm really wanting to keep it since the numbers are comparable to that of an RX7 swap. Here's the latest pics of the trans tear down and I'm going to start a thread in the main B series section as well about this (since this is a diesel conversion thread, not a trannie topic

)

For what I know to be true, if I use the 5th gear set on my trans, I'll lower that gear ratio from 0.52 down to 0.42 (note that I know that this isn't final drive ratio, I'm going through old text books to figure out how to calculate that, but I know that somehow the 0.52 equates to a .858 final gear ratio.)

In addition to the reverse synchro ring and the higher overdrive gear, I'm noticing that the bearings on the bongo trannie are in a lot better shape, and are sealed units, than my trannie bearings. The ones that I can transfer over easily I'm going to go ahead and do that.

the b2600 5th gear is .816 and you should be higher than that actually. And you should kill a rx7 tranny swap easy. Its your tranny your the loucky one who found it. I might just have to find another one. You know if i get a bongo tranny and use the kia bottom end were both gonna be in the same predicament on the starters and everything.

well, I know where to get a starter, the biggest issue right now is funding, and I'm still having a bear of a time finding a machine shop local to me that can o ring the cylinder head. Most of them I've spoke to are like "huh? what do you mean o-ring a head" **click**
