40 IDF vs 44IDF on 8VTC

Choosing twin carbs for your 8 valve TC on 1800 cc or 2000cc engines it is recommended that you have a big valve head before jumping up to a 44 IDF or a 45DCOE twin carb system.Max choke size on a 40 IDF is 34mm,44Idf starts with 36mm chokes,(depending on engine modifications ,valve sizes,pistons et...

Re: 124/2000 Stock Suspension Coil Springs

I would contact pierce manifold and see what they recommend.They might be able to re-bush that for you,what about the throttle shaft,if that is worn,you will need that redone as well,buying a replacement carb might be ,or finding a used one for parts.Thad Kirk is an 850 freak,drop him a line,he will...

casting No#

Csaba, Your right,in the US.These are Fiat no#s printed from their engineering manual.Those general casting no# were used apparantly for more than one design,different markets etc..Csaba I have a Clean 1592 head on the bench,it looks like the best stock head to use on an 1800/2000.no egr plugs etc.....

TC 84mm and 1592cc Combustion Chamber Offset

84mm bore and 1592cc (80mm bore ,sister engine) not including 16v engines is that no1 and no4 combustion chambers are offset 3.5mm toward the crank centre journal.This resulted from the use by FIAT of the same patterns for the 1608 cc head castings being adapted to suit the longer 84mm block.

heads

Casting no# 4372291 41.8 inlet valve 36 ex valve (mm) was used on 2 litre and 1800 blocks,unleaded seats.That casting no# I'm pretty sure was used from 76' to 79 1800/2000 cars. Earlier heads with the the 43.5mm inlet valve will up the compression in 84mm bore TC's and can increase power up to 10bhp...

Haeds and Pistons

Yes Ron It really is a myth.I used to think the same thing,I will take some pictures to show you the difference between the two piston types.A 2 litre engine has a longer stroke(90)vs (79.2)mm in the 1756 engine, same 84mm bore.A 1592cc head does have a slightly smaller combustion chamber and is a s...

1800 head vs 2 liter head

Ron, That's a Fiat Twin Cam Myth,the combustion chambers sizes are the same. A 1608 and a 1438 are a tad smaller but can't be used on the bigger engines. 1800 pistons will up the compression slightly in a 2 litre block because of the smaller fly cuts. But why bother to even do that...just install 9....

LSD posi rear for spiders

This is the link to Phantom Grip.You can have a stock rear made into an LSD for your spider,or just about any Fiat for that matter.Some simple, machine work might be needed on some differentials.I believe Vicks is selling this set-up in the 3:90 LSD they are advertising.here is the Link: http://www....
