Hi all, new to the forums. I am possibly going to receive my father's 740 turbo sedan (1986 I beleive, rwd and automatic) b/c the engine is on it's last legs. The local shop says that a rebuilt engine installed is going for around 3500/4000 for an exact replacement of the intercooled 4cyl. Is this too much? Is there a better engine that could be put in there for around the same price?<P>I'm a VW guy myself but if there is a feasible way to get this sedan up and running I'll probably sell the VW to save the money on payments.<P>Thanks for your help, look forward to hearing some of your responses.<P>

For $4K, you could buy a nice '90-'92 740 Turbo with a better engine and probably fewer miles.<P>You could buy a used B230FT engine (the one you have) for about $500-$1200. The price depends on what year it comes from, because the later ones are better, and it depends on mileage. If you can afford it, and you plan to modify the engine, try to get a '94-'95 B230FT from a 940 Turbo. If you just want to run stock boost (around 8-10psi), then try to get a '90 or later engine. Don't get an '88 or earlier unless you have to.<P>The '85-'88 B230FT was not very strong. With raised boost, it's not that hard to put a rod through the block. I think it was mid-year '89 that the rods were improved (13mm instead of 9mm). In '93 piston cooling was introduced. The under sides of the pistons are sprayed with oil which helps cool them and decrease detonation. I think the '93 engines got longer pistons skirts too, so the pistons don't "rock" back and forth in the bores as much, which is a source of noise in the older engines. The '94-'95 engines had the piston cooling and reinforced blocks, so these are the best for high boost applications. In stock form they'll last the longest.<P>There's at least one good source in the area for a used engine (I live in Herndon too, BTW). A guy named Brian Leppin down in Bryans Road, MD has a Volvo salvage yard, and he often has B230FT engines. His prices are always good, and will sometimes offer a guarantee on an engine or transmission (30-100 days). He may even deliver it, since you're within 100miles (not sure if he still offers that on big items or not). Here's his info:<P>email: [email protected]<BR>phone number: 301-367-2244<BR>website: <A HREF="http://www.volvousedparts.com/" TARGET=_blank>http://www.volvousedparts.com/</A> <P>Do a compression and/or leakdown test on the engine before buying it and maybe check the oil pressure too. Before installing it, replace all the seals (3 front seals, valve cover, and rear main seal. shouldn't need an oil pan seal). Service the PCV system and change the water pump and install a new timing belt. Good time to do heater hoses, radiator, and radiator hoses too. Here's another useful resource on the 700/900 series cars, from the <A HREF="http://www.brickboard.com/" TARGET=_blank>brickboard</A> (go to this site too if you haven't been yet).<P><A HREF="http://www.brickboard.com/FAQ/700-900/" TARGET=_blank>Volvo Maintenance FAQ for 700/900/90 Cars</A><P>The engine and labor to install it with some new parts should be $1500-2500. Much better than 3500+. Let me know if you have any other questions. The Brickboard is great for maintenance questions, and the <A HREF="http://pub55.ezboard.com/bturbobricks" TARGET=_blank>Turbobricks</A> message board is good for performance related questions.<P><B> <BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>I'm a VW guy myself but if there is a feasible way to get this sedan up and running I'll probably sell the VW to save the money on payments.</B><HR></BLOCKQUOTE><P>Do you post at vwvortex too? What kind of VW do you drive?<P>

That's exactly what I would have said. While you're at it, trash the stock turbo and stick a Garrett T3 or T4 unit on there, with a boost controller. I'm not sure what kind of power the tranny and rear end can handle though.<P><BR>If you don't care about making it fast, just get a rebuilt (or otherwise healthy) B230FT from any 740 Turbo or 940 Turbo and drop it in.<P>

The '90-'95 740/940 Turbo is faster with the smaller turbo than the '89-older cars with the bigger turbo (stock). With increased boost, the bigger turbo will make more power and boost higher before it becomes inefficient, but it's not going to be quite as good for low end response and daily driving. It really depends on what you want from the car, though.<P>The Mitsu exhaust manifold needs to be machined flat to fit a Garrett turbo. Some '90-on cars had a small Garrett, so it would be easier with that manifold.<P>If the engine comes with a good turbo, use it. The '86 740 Turbo was the last to use a non-watercooled unit, so the newer ones will generally last longer and require less cool down time.<P>

Michael,<P>How about a V8 conversion from a Ford 5.0 or Chevy 350? I wonder what the price range is for doing one of these jobs? It sure would make the ultimate 740 sleeper.<P>-Drew<P>

I don't know how much modification it would require though or how hard it would be to make it fit.<P><BR>You can get a used Ford 5.0 for under $1000. Then if you spend another ~$1000 (maybe a little more) modding it, you're golden.<P><BR>I'm very familiar with Ford's 5.0 and it is an excelent engine. If you want something bigger, Ford's 351 Windsor (5.8L) is also out there. There are also stroker kits available for both the 5.0 and 351 to make just about any displacement (well not any, but a lot of different ones) up to 400ci or so. There is a phenomenal amount of aftermarket parts available for both of these engines, and either one will push your Volvo into the 12-second range easily with the right parts, quite possibly cheaper than rebuilding your existing engine.<P><BR>Since it's a domestic powerplant and Ford used it for something like 20 or 30 years ('95 was the last 5.0 Mustang, the 5.0 continued in the Explorer until '98, but stockpiles of these engines still exist) it is available relatively cheap. If you're interested, I can find you some prices and places to buy from.<P><BR>EDIT: Look what I found:<P> <IMG SRC="http://media4.motorcities.com/01FAA592248022G.jpeg"> <P> <IMG SRC="http://media4.motorcities.com/01FAA592248022H.jpeg"> <P> <IMG SRC="http://media4.motorcities.com/01FAA592248022I.jpeg"> <P><BR>1988 760 with a Ford 5.0 <IMG SRC="http://www.swedespeed.com/ubb/biggrin.gif"><P>

It didn't seem like a viable option in this case since it sounded like replacing the engine with another B230FT wasn't a DIY job. $8000 will buy a turn-key V8 swap from Ross Converse, and it will probably take a while to get it done. I have no idea where to look for someone to do a V8 swap, nor do I know how much it might cost. Plan on $2000+ going towards the Converse kit/engine/trans.<P>

Converse Engineering in Maine sells kits for the install and is quite experienced with the swap. You may want to look into that if you are considering the V8 option.<BR> <A HREF="http://www.converseengineering.com" TARGET=_blank>http://www.converseengineering.com</A> <BR>

Then another $400-800 for the transmission. If you're mechinacally inclined and can handle the project, do the conversion yourself (I would) and save the labor charge, shouldn't be all that expensive.<P>

Hey guys thanks so much for the information I really appreciate it! I'll definitley look into things.<P>towerymt: yes in fact I do and have been posting there since early 2000 (novaVR6).
