waking up the b18 in my 65 122s

What ever you do stay away from VPD and John Parker. There are plenty of other places to get cams. Isky and Schneider are two that come to mind.

I would suggest boring to B20 displacement and using a stock E head. I can promise you won't be unsatisfied with the improvement over the B18.
 
ive heard the kd needles are great. from what i hear thats what came in the 123. where can i find such a thing? im hearing conflicting things about using a b20 head on a b18. some say it works well, others say no fn way! does anyone have first hand knowledge?

I've not put a B20B/E/F head on a B18, but put several B20E/F heads on a B20B. It should work, but not the best combustion chamber when your done.

The 123GT came with a B20B and if equipped with the KD needles was fairly done over to gain the correct a/f ratio. The KD works well on a B20 where the flow is much greater. On a B18 it would need some good porting work, hot cam and plus size on the bore, too. If the B18 head is mildly worked, then the stock SM needles for a B20 will be your best starting point.

to compare the needles, go here:

To buy them order from SU directly or one of their US dist.
 
if the bottom end on this b18 wasnt nice and tight, i got 165-170psi on all 4 cyl when i did a comp test on the dead cold motor, i would absolutely bore it out. im also working on a budget here. the d cam looks like itll perform well w the stock b18 bottom end and some decent porting on the head. looks like ive found an m41 to put in her and possibly a set of hif6's. would the hif6's perform considerably better than my hs6's w a kd needle?

Try Bob Griffith at bhpdev@ptd.net for a cam, he has a great street cam. Truth is, he is the developer of the cams that the a**hole sells. Bob has been around B18/B20s for over 30 years.
 
Here are the pics of the manifold I have. I seem to remember it is from an injected 144. It looks like it had an air pump, hence the 4 blocked off ports. I think the flange thickness is different between injected and carbed cars, so it may require some creative washers. JohnMC, does that sound right?

does this manny bolt right up to my b18 head? will it flow enough to keep up w a fairly good amount of head porting, slight shaving w a .030 hg and slightly bigger valves and a stock (tight) b18 bottom end?

Yes and yes. Volvo Competition Service specd the F/I manifold as an upgrade to B18 engines.

The replacement manifolds all came with plugs for the air injection ports so they would fit any year. Only 75 240's used them AFAIK. The manifolds are definitely different thicknesses. F/I manifolds being thicker than than the carb ones. You can also cut apart a unified cast intake and exhaust manifold from 68-, the 67 one's are too rare to cut (no stupid flappies in the intake). I have a machine shop cut down ? a piece of flat bar the difference of the thickness of the manifolds, then use a hole saw to cut out washers starting from the flat side. Welding together half washers is a bitch, but I've done that too. The thick material is for the super thin flange on my Stahl header and thick D-Jet F/I intake manifold on my 142E.

Thanks hyperfauto, it's been so long since I really played with pushrod stuff that I could only sort of remember the details :) Brickdaddy, if you keep your HS6 carbs, you will also need your 2 throttle return spring washers. If I can find an early intake in my storage unit I could probably make some stepped washers for you.
 
wow, what a pita those washers look like! i am planning on running my hs6 carbs w dx needles so it'd be real cool if you could hook me up w a set of washers thatd work for me. i can pp you the moolah as early as monday if you could make it all happen. could you possibly send me a pic of the needed throttle return spring washers? thanks for all your help good sir!
 
I am headed out of town next week for work, but I can whip up some washers when I get home. Don't worry about sending money until I get it all done, I don't like getting $ until I have everything boxed up and ready to ship, just in case something falls apart on my end ;-) If you look at your carbs, there should be 2 throttle return springs running to washers with little eyelets on them. Do not lose those when you take it apart. They are a royal pain to recreate.
 
The 1800E downpipe has a 2" outlet and is easier to ship because it's short. You can have a custom exhaust fabbed up from there.

sorry my friend. im dyslexic. misspell stuff all the time. i dont see words the way usual people do. but again, sorry. id much rather buy from you. keep it in the family, ya know! just let me know when/where to send the money. what would you want for it shipped?

Mike Dudek from IRoll motors also sells this DP and the entire Simons exhaust system. I have one on my 122 and absolutely love it. Has a very "sports car" sound to it, and has definitely woken up the motor with the dual plane exhaust manifold.

No sweat. I proofread my posts 3 times and still misspell stuff (even with spell-check). I'll call tomorrow and get a quote for shipping, and find out what my price is. PM me your shipping info.
