View Full Version : B230ft swap, newbie questions

So I have been researching swapping a b230ft into my 145. I have a line on a late 80s motor from a 700series at a great price which I would do a complete tear down on (new rods, pistons...) if I go that route. I would like 250hp out of it and reliability as it is my daily driver. I will be running a SDS stand alone and T-5 tranny. I am new to the Volvo world, so please excuse the questions if they seem kinda retarded.
Motor Mounts... is this a direct bolt in, or is going to be some massaging needed? I think I read somewhere that I have to move the dizzy to the front.
Fuel delivery (new fuel pump) do I need to plum in a return line, will the stock tank work?
Is 250 realistic? If I'm going for that should I just go for 300hp (forget that it's a 145:roll:)? Can the motor take that with out constantly needing attention (above and beyond a thorough maintenance schedule)?
I thought I saw a few places/members that sold headers/manifolds (RSi...) and intakes? A point in their direction would be helpful.

Thanks

250-300 hp is a realistic goal. But it will require some parts and fabrication especially going in to a 145. The motor mounts are not bolt in and will require fabricated mounts. There was a member here selling motor mounts for that swap but I don't remember the user name. The distributor if you use one should be moved to the block like on a 240. You can swap in the intermediate shaft from a 240 if you need to. Most B230FT don't have the drive gear type intermediate shaft in them. You have to plumb in a fuel return line but it shouldn't be a problem since you could use a fuel injected 145 fuel tank or just put in your own fitting.

A well built engine with late B230FT internals or even better aftermarket internals should still have a good service life if it's not abused. People have made this kind of hp on their daily drivers and the engine is reliable and powerful. It's the rest of the driveline like the trans and clutch which will also need upgrading. You have the right idea if you are planning on a T5 trans. RSI and JVAB sell upgraded internal parts and more.

I was a little worried about it being a non-squirter block, but I think thats ok. I see RSi sells bigger rods, although I'm not building a race motor, just a fun street motor, it's probable a good idea to add them to the build and go for 300hp. So I think I'll pick up this motor and get started on it.
I found a good write up on the distributor issue, as well as other swap info for anyone else looking...

but, as stated...'The distributor if you use one...' How does one do away with the distributor?

Any other parts site, someone who sells custom parts off the board or build threads that someone could point me towards would be a great help as I slowly put together the pieces for this build. Any suggestions or comments about the build are welcome as I am new to the Volvo world. I'm coming from Ford 302s and Cheby 350s... gasp!:omg: So this is a sharp learning curve for me. Hey, at least I get to bring my T-5 along!

If you just want a fun street motor, the right combination of stock parts will get you a reliable bottomend. Squirters are by no mean a necessity on a street motor imho. You see a lot of nuked bottomends on this board but you also see a lot more horrid tuning etc. The difficult thing with volvos is that there are so many different paths to follow. Everyone has their opinion on what the best direction is to go and there is a lot of conflicting advise on here. I suggest you read awhile and decide where you want to go before investing a lot of money into parts you don't need. Checkout Yoshifab (http://www.yoshifab.com/store/) we sell a few party you might be able to make use of. RSI also offers some real nice parts.

Yes, there are a lot of different paths to follow in the Volvo world... the reading has been a bit overwhelming but should all meld in due time. I would totally be in the dark if it weren't for boards such as this. This is by no means going to be a rushed build as I have been down that road before and ended up with bad results. Like you said you may have all the best parts, but that doesn't mean much without a good assemble and tune. Most of the work (engine build, SDS) is going to be done by a local shop specializing in turbo cars and aftermarket engine management systems, particularly SDS. I , however would like to do as much as I can. Mocking up the motor, fuel lines and such... so it's back to reading. It's funny, one thread leads to the next and before I know it, I have 4 or 5 different pages open.
