B230F+T questions

[charlesridgway]

Currently working on turboing my 91 b230ft using a td04 from a 940. Ive got it almost all figured out besides the oil filter adapter and the oil cooler lines. I understand that water and oil hook up to the adapter, and im assuming that the 2 big hoses coming out of mine are for water? Also I’ve heard that a filter adapter going bad can mean ur motor so how should I inspect mine to see if its chill?

Im also lost on the oil cooler. Ive got one ready to go but no lines. Where is the oil cooler looped into the oil circulation. At the adapter?

Not to mention, my turbo itself is a little gunky even under the open oil feed and return holes. is that something u can just toss inna parts washer?

Thank you to anyone reading!

And lmk if you or a friend needs a 940 intercooler, or a 740 turbo radiatior in nice condition!

edit: I found this picture under an ipd listing for the filter adapter but not sure what to make of it

You need the steel water line that goes from the water pump to the heater core hookup behind the head off the 940. It has a Tee in it for one of your water lines then you need the water line that screws into the block where the block drain is for the other water line. The oil gets cooled in that big chunk the oil filter is screwed onto. You could always lightly pressurize or somehow vacuum test the oil cooler body with the water ports but mostly just look for milkshake colored oil in it.

There are no oil lines that hook up to the sandwich plate.
Just the two water lines.

As it was already mentioned, the coolant pipe that goes from the back of the water pump to the heater core is different on Turbo cars and has a T where one of the lines of the cooler attach.
The other line goes via a hard line to the coolant drain port in the block.

Skandix has a good illustration and parts list (https://www.skandix.de/en/installat...00/Oil-cooler-with-Water-Oil-cooling/2000741/)


The big arm is just a relocation bracket because the filter is in the way of the turbo.

Every single part you need is still available from what I can see except the short pipe to the block drain.

Well I also have one of these air oil coolers. On my buddy chases car which I looked at for reference had these oil lines running to an oil filter sandwhich plate like in the second image. Since I dont want to buy all the stock water lines and stuff I’m planning on just running my oil cooler like that, and water to the turbo from the expansion tank hose. I think I could get a generic sandwhich plate like this one. Not sure if it will be the right thread size though. Probably just gonna get aftermarket oil cooler lines but what do yall think?

You need a different sandwich plate then, coolant is the only thing that goes through the one you have, the oil stays inside.

Ok update I ordered a ebay thermostatic sanwhich plate that I will make work for the time being, but I’ve got a b21 oem wahler plate lined up that I’m gonna run eventually. In the meantime, what do yall think about na fuel pumps on a +t? Is it even worth trying? If i do need a new fuel pump is it possible to just get a new in line fuel pump and not have to upgrade the in tank one?

I also heard you can run an AFR using the stock o2 sensor wire. Anyone know what kind of AFR I would need for this?

I would start with the N/A pumps and see if you run out of fuel, then upgrade appropriately.

If you need high capacity pumping the best choice long term is probably to switch to a single in-tank pump like modern cars use. It's been done pretty often and takes some work but is not too bad.

Running one fuel pump!

I want to run one fuel pump, my car is a 89 760ti LH 2.2. What all is involved? I have been searching around and the most info I found was in this post: http://forums.turbobricks.com/showthread.php?t=137152 Is it the same for a 7 series? I want to run a walbro 255 and delete/bypass the under...

the stock O2 sensor is a narrowband. You probably want a wideband instead for diagnostics and tuning, so it will need to be replaced. many (but not all) off the shelf wideband setups will also provide a simulated narrowband output to feed into the stock ECU.

Awesome! Thanks for the info. For now I think I’ll finish my +t and if shes not running beautifully I’ll look into fuel pumps and afr
