1.8 turbo motor

[vwpro]

Turbo GTX3583R garret.

It will use a 1.8 16v steel crank, we will use a abf block and head with 82.5mm wossener forged pistons and Eagle forged vr6 164mm rods, block will be sized to suit setup for a 9:1 comp ratio, girdle plate on bottom and will use full set ARP bolts bottom and top, fully nitride and balance bottom end.
Mod the 20v intake manifold and custom build exhaust manifold. 48mm waste gate and 48mm blow off valves.76mm s/s exhaust with mandrill bends, and why we doing this? so we can run higher rev range, previous n/a one run 10000rpm with no issues what so ever.
Rod ratio on this setup is 1.898


all pro`s and con`s below.

Long rod pros:
Less rod angularity
Higher wrist pin location
Helps resist detonation
A lighter reciprocating assembly
Reduced piston rock
Better leverage on the crank for a longer time
Less ignition timing is required
Allow slightly more compression to be used before detonation is a problem
Less average and peak piston velocity
Peak piston velocity is later in the down stroke
Less intake runner volume is needed

Cons:
Closer Piston-to-valve clearances
Makes the engine run a little more cammie at low rpm
Reduces scavenging at low rpm

Short rod pros:
Increased scavenging effect at low rpm
Helps flow at low valve lifts (a benefit if the heads are ported with this in mind)
Slower piston speeds near BDC
Allows the intake valve to be open longer with less reversion
More piston-to-valve clearance
Can allow for a shorter deck height

and cons:
More rod angularity
Lower piston pin height (if the deck is not shorter)
Taller and heavier pistons are required (again, if the deck height is not reduced)
More ignition timing is required for peak power

Things that I gleaned that are of direct interest for those of us that are boost-assisted:
Ignition timing.. less advance is needed with longer rods, which reduces the chances of detonation(well, detonation brought about by aggressive timing). Another thing of direct interest is longer rods don't move as fast and thus lower the reciprocating load placed on the rod, which is supposedly the leading cause of rod failure..

Interesting setup, curious to see outcome. Nice turbo btw.

Will save this for an Mk1 one day

What mods was or will be done to the head to support the higher reving range aswell?

stage 3 head flow job, solid lifters,titanium retainers, audi rs4 4.2l v8 forged double valve springs, with SINUS titanium valves and cotters http://www.sinusperformance.com/en-us/p ... rformance/

When this moster is built, please oh please post pics and vids, it's the stuff of dreams!

when you dyno and tune this beast i would love to see the results ....please crack 400hp on the wheels !
Is the 1.8 16v crank stronger than the stock 1.8t crank ?
do you know if the 2 litre 9A crank is also steel and strong ?

[dood786]

This turbo is good for 600+hp

This turbo is good for 600+hp

GTX3582R is rated for between 450 and 750Hp

I will do that, this is for the caddy when 4x4(audi TT quatro) drivetrain installation is done on the caddy

maybe, can`t say, but know the 1.8 16v steel crank is strong, have to use it as I use a ABF block

if you have 053C mark on the crank its a steel crank, best on 2.0l cranks available.
