Hi guys im Chasing a 95-98 940 b230ft block to build for my speedway car i dont need/ cant use the turbo and dont need starter or altenator or injection basically bare with internals prefer in qld but could organise freight at the right price
So you want a non turbo b230f then? There is no difference in the motor from 93 on, it's there a reason it needs to be 95?
Thats just what i was told i needed for what im gunna use it for
Maybe you've had it explained wrong, because you can open up your options, so what is the purpose exactly?
Its gunna be used in my speedcar on methanol with ported 16v head
With new pistons? If so, any 93 on block is suitable with squirters.
The 93 model year (7/92 build) on motor has oil piston squirters stock, with any luck it means the bore is still perfect. But I've seen non oil squirter blocks with good bores after 200,000kms too that did not need an overbore.

I'm guessing you're using the yoshifab.com 16v kit.

I'm in Melbourne so my sources are useless as there will be parts up in Queensland. However I am keen to see the results!
I have one im currently leasing makes about 200hp but i need around the 300- 350hp to be consistently competitive have a video of it but unsure how to post here
300hp on a na engine?! That's possible? Please keep us updated!
Yeah theres a guy ive been speaking to who has 356hp out of a n/a on e85

If you have the pictures hosted on another side, just post the URLs to the pics. They would be interesting to see.

You can source the correct engine block for your goals out of any 940 from 1993 year model onwards (donor car will have a 'P' in the VIN). These are the so-called 'L' blocks. They are identifiable by having a rounded tooth timing belt.

If it's for a Speedway car wouldn't it be easier to fit an actual B234F than modify a B230 to take the 16v head?
volvomidget;121623 wroteNot sure how too post them
If the phone has internet access upload the files to a site like www.imgur.com; or browse to them on the phone and open this page then drag and drop them on this window; or email them to a computer and then drag & drop here.

If no internet access on phone, connect it to a computer via a cable, copy files over, then do one of the above.

The Volvo Penta AQ171 (aka 251DOHC) was essentially a B230 with a long stroke forged crank, a pair of Solex carbies, a Bosch electronic ignition, and a bunch of boaty bits for exhaust and water pump, etc. Here's some pics of the one in the Volvo Museum. You can see its still got 'B230' on the block.









So fitting the 532 (aka 16V) head on a B230 block isn't a big deal.

Using the B234 block carries a number of disadvantages. It means you are forced to use either a head-mounted distributor, or a trigger wheel on the crank pulley or flywheel in order to do ignition; unlike the B21 / B230 blocks, the B234 block doesn't have any auxiliary shaft to run a distributor or a conventional redblock oil pump. The B234 oil pump is mounted in the front of the engine and is driven from the timing belt.
I know what is required to fit the 16v head onto the b230 as I have one that has been modified to fit.
How is having a head mounted distributor or external oil pump a disadvantage of the B234 if its stock fitment on the motor, is reliable and doesn't need changing?
It's going into a speedway car that isn't hampered by firewall or inner guard or engine mount issues which is the reason why the B234 doesn't easily fit into the space an 8v redblock usually resides. A couple of engine mounts and it's done.

I know nothing about sprint car rules, but they may require a points-based ignition system, so I may be completely wrong about that.

The oil pump issue is a reliability problem - the B234 oil pumps were made only for the four-year run of B204 and B234 and they used to break oil pump pulley bolts and take the timing belt to oblivion with it when they did. On top of that, the oil pump pulleys were known to crack. Even in Mum and Dad road car use. Again, the pulley was a uniquely B204/B234 part, and they are NLA from Mother Volvo. Nobody in the aftermarket AFAIK makes oil pump pulleys for them, either. These are not good omens for a competition engine that's going to spend much of its running life revving its mammories off.

OTOH the B230 oil pump has been around forever; quality replacement pumps are easily obtainable from Mother Volvo and Melling, and when the little retainer ring is used on the pump drive, they very rarely fail in competition use.
