While I'm waiting...

Not too much going on around here lately, so I figured I'd make a thread to ask for a few suggestions.

Since my car is totaled and I'll probably have the engine out all winter if I can find a garage, I was thinking of working on it some.

I did most of the regular wear and tear parts when I put it in originally, so I was looking for more suggestions on how to build it up a bit.

I'm mildly intrigued by the idea of putting a snail on there, but I'd need to do a LOT of reading before I'd feel comfortable putting a turbo in.

Anyway hit me with some ideas.

You can do what I did, take it down to the bare block. Replace all wear items, and then you when decide to turbo all you'll need is good headgasket and studs :)

I just might. On a side note, and because I don't feel like searching because I'm tired, is there any difference between the b32, b34 and b35 intake manifolds? Besides cosmetically I mean. Just curious.

Yeah, lack of port for the brake booster for one. Mounting holes for the brackets to the valve cover...maybe more? Then IIRC it was b32s that had 2 piece intake manifolds? Might be wrong on this, going by memory here.

Maybe the early b32's. AFAIK mine is a one piece intake, it looks just like the b34 ones with the brackets to the valve cover.

I'd have to take another look at it.

I want to get working on it, it's tough losing the only garage I had access to. Maybe I can convince my girlfriend's dad to move his 39 Ford out into the weather instead of my car...

I've entertained quite a few ideas in the past week or so (easy to do when you get fired and have nothing to do) including turboing, itb's, as well as a few other slightly more insane ideas.

I was considering using a b35 head for a while since there was one available locally but according to various sources that would lower the compression ratio from 8:1 to 7 something:1 which would be kind of a waste unless I wanted turbo right away.

However, coming across this old thread,

Euroshark mentions the m10 pistons available from IE. Now they're relatively affordable but I was curious as to whether it would be worth bumping my CR up to 8.5 or 9.5:1

So that's what I'm looking into now. Of course I have to get a car first.

Yeah, the intake ports on the b34 are smaller than on the b35 manifold. You would have to have the b35 manifold port matched to line up with the b34 head correctly. Other than that the only differences are as Jean noted as far as I know. Also if you are seriously considering aftermarket pistons I can put you in touch with someone that has tons of specs and research on M10/M30 performance. Feel free to drop me a PM.

This is interesting, some info I got from Paul, who wildstoats referred me to:

You can stick with your B32 as it is the same stroke and will take a 92mm bore ending up the same dimensionally as the B34. If you decide to swap it for a B35 stay away from casting dates newer(later) than 1of 88 . These blocks are a lightweight version of the B35 and not a good turbo platform (decks crack). The only B35 block that I currently use bares a late 87 casting date and is rather hard to find.

All the B35 heads are the same and have a larger intake port than the B34 which works well when a turbocharging.

If you decide to use the B35 head on the B32/34 short block it will require a custom piston (flat top is approx 9 to 1 ) .

You will pretty much have to commit yourself to a N/A build going any higher than 9 to 1 on a street engine . If you want to gain any worthwhile performance out of the B32/34 (N/A without turbo) it will need to be at least 10 to 1 comp. which will all but rule out adding a turbo.

If you want to combine stock parts and stay normally aspirated for the moment, I would get the B35 short block (has flat top pistons) and use you B34 head (60cc chamber) which will result in a comp. ratio of approx 9.6/7 to 1, combine that with a decent cam and you will have a nice (very cheap) 220hp M30.

There is one draw back however, all the B35 blocks except the 87 date coded ones only have the E32/34 pass. side motor mount provisions so you might have to deal with making a new motor mount bracket.
