As title.
As hard as it may be to believe, HKS (ie the famous jap tuning company) once tuned BDAs!

I know bugger all about it, but just reading (well, not, just looking at pics ) a tuning mag from Japan, and it has a small B+W pic of a BDA with a HKS cam cover.
"HKS SIGMA" on the one side, "FORD" on the other.
Proper cam cover with the writing cast in to it, not a sticker or paint like.

Long shot, but anyone know anything about em?

Must have been before HKS made it big, they wouldn't waste time on Fords now.

what car did they put it inn?

It probably relates to the tale that a 4age engine is similar in dimension to the BDA,

That'll have been the engine they imported to copy.....

Tony Ryan

I dont think its a BDA , i reckon its an FVA or another derivative ,



1966-68 , Brian Hart Designed and featured in many period sports and single seaters , a lot of these would have been home tuned in Asia , i assume thats where the rocker cover design comes in , a bit like warrior or burton used to do with x-flows and v6's etc..

Stavros

Its got the BDA water pipe bit on the side of the head etc, did others have that too then?

And it says BDA in the writing, and Option magazine usually are very very correct, esp as it was a feature on the history of HKS.

Sure does look like the pic you posted tho

Interesting indeed. I wonder what they made of the Ford engines in terms of tunibility etc...

Anyone remember that feature in Max Power when they brought over a Jap tuning boss (Top Secret's main man maybe?) and tok him out in a fast white Saff Cossie (Mark Shead's?).

that engine starvos pictured isnt a cross flow is it, looks like the inlet and zorst on same side of the head?

didnt think the bda came in that format?

Stavros

i presume you have never seen a crossflow then.

and the inlet and exhaust doesnt come from the same side on that head.

zippyobrien

iTrader: (2)

i no that, read what i said,

i thought all bda engines WERE of the cross flow formate.

the one youve pictures looks like there both on the saem side of the head.

which is why i asked if it was a bda, as i thought all bdas where crossflow

Munch

Crossflow is an 8v mate

zippyobrien

iTrader: (2)

i just ment cross flow format, not the engine name,


in the picture starvos put up, you can see round holes and oval ports,
are the round ones core plugs? or ports aswell,

thats all thats confusing me dude

xr2i-carl

cumon guys lets get to the bottom of this one

Stavros

2 things mate.

the inlet and exhaust ports on that engine are on different sides.

and you might want to learn what a cross flow engine is before you say that looks like one if you think it has the ports on the same side

ian sibbert

Seriously Steve, It looks to me like a BDA,

But it is a little hard to 100% confirm....

best pic I have of a BDA head...

zippyobrien

iTrader: (2)

ive already said that i understand the difference, slow down and read what ive wrote,

all i originaly asked was if the ports on the engine youve pictured were on the same side. and youve answered so cheers dude.

incedently, what are the round holes then, core plugs?

and i no that a cross flow is a push rod 8valve, with the inlet and exhaust on different sides of the engine.



has any one worked out what the hks lump is then?

Stavros

Ian- exactly, looks just like a BDA, soon as i saw the water hole and the ports i recognised it.

fook knows what HKS used to do with it tho.

"Sigma" is what the S in HKS stands for tho, ive found that much out.

H-Hasegawa, as in Hiroyuki Hasegawa.

K-Kitagawa, as in Goichi Kitagawa.

S- Sigma, as in Sigma Automotive Company, Ltd.

Hasegawa and Kitagawa formed the company with the assistance of capital infusion from Sigma Automotive, hence the name HKS...

wasnt one of the toyota engines very similar to a bda ???

like ian said at the top, whats the story behind that?

ian sibbert

Although the it says BDA in the Jap txt, it could well be one of the kits sold by cosworth into racing and rallying in the late 60's early 70's....they were identified as a BDB and BDC respectively, the BDC being fuel injected....1700cc engine, IIRC producing about 200 BHP

ian sibbert

As with everything the Japs do best, they looked at the best engine at the time (the BDA) and copied it, then mass produced it and slotted into some production cars, the mk1 MR2, the Toyota Coralla and many others had basically a BDA in them.....

Stavros

Zippy- Toyota 4AGE engines are very similar, incredibly similar, to 1600 BDA engines.
They later made a 5 valve per cyl version that was even better.

Ian- HKS first existed in 1972, which kinda tallys up with that.

ian sibbert

Its my ambition to own a mk2 with a BDG in, for when I'm old and grey....lol

I love BD's....

Tony Ryan

iirc, the FVA and other period versions used the pre-x/flow block , 5 bearing old 116e unit , its that i think in your mag cutting as the block is deffo not a later x/flow one . The BDA was a later engine really designed to replace the lotus twin cam and was Belt driven , not gear driven like the picture you posted .

HKS definately dont just do Jap stuff, for example they did the head gaskets on a lot of the big power XE vauxhall engines.

(still available now at silly money)

JohnnyB

its not a BDA, its some sort of jap copy but its not a BDA or FVA

Block is wrong

foreigneRS

if you put up decent pictures of the whole article in japanese i can get it translated for you if you're that interested in reading it?

JohnnyB

what were the japs good at ofter the war, steal a good desgn and make it better.

Point incase above

Tony Ryan

looks like a later Hart block

ian sibbert

You thinking its a 420R.....now that is some engine

GARETH T

as its not belt driven,,, i dont think its a BeltDriven derivative at all!

ian sibbert

The later Hart engines (as that pic) were chain driven, they were still derived from a BD....they were a later engine made IIRC about 1976 - 77

GARETH T

Ill shut my mouth LOL

ian sibbert

Trouble is they changed design,

same 420R but belt driven...



People even today are changing designs of engines, Wilcox or Jondel are doing a belt driven Duratec, Steve Banister has one in his car...

Stavros

What would be the reason to go from chain to belt anyhow?

foreigneRS

possible reasons would be:

less noise with belt - not really applicable with a race engine

less inertia as there is less weight to accelerate with a belt

ian sibbert

I'm sure others will disagree, but the only reason I can see would be the hydaulic tensioner on the chain drive, from initial start-up, some race chain engines had a habit ot skipping on the drive, other than that the chain is probably better, IIRC Roy Millington did some chain some belt, the later milly's are now belt driven....

JohnnyB

its not a hart block chaps, I am a total fucking nerd when it comes to old cossie engines.

But I must admit I know more about BDA than FVA

But the Hart BDA block was amost a exact copy of a Xflow block, but in ally

JohnnyB
