Internal Engine Mods? Help/Suggestions Please!

[DBoy 0]

Ive got a 1992 Vento VR6 with the engine blown at the bottom end.

Rather than buy a new/used engine to stick in, i am going to temove the blown engine and get it sorted properly!

Ive recently bought a Crankshaft and Pistons, as i know they are f*$ked.

I know that the head will need re-skimming, and i am going to have the crank that i bought re-ground.

As i am going to go to the trouble of pulling the engine out, I would just like to know what i could possibly do to the engine, in terms of internal modifications to possibly improve the BHP/power/torque?

Probably the main one would be a bore/stroke conversion, but that wouldn't sit too well with either your new crank or piston purchases. I've seen adverts to go to 3.1L on the standard 2.8L engine in Golf+

Cams of course, but they alter the power band of the engine and that might not be what you're looking for either.

You could get the crankshaft and flywheel lightened.

[vr6turbo 27]

crank, conrods pistons balanced

arp conrod and main bearing bolts

expensive but super strong 2/3rds sronger than stock

heavy duty oil pump

rods shot peened to strengthen them

ceramic coating on the piston crowns

forged pistons if you are going forced induction

total seal rings

are the pistons the same size as the ones you took out?

if so you will only get half a job done.

the bores will be worn if the engine is the original one

you should really as mentioned get a rebore and use 2.9 pistons, or go for 3.0 pistons,

you will have to get the cylinder walls checked to make sure they are thick enough to take the 3.0ltr piston rebore

have a stroked crank and go to 3.1 or 3.2 ltr

the mods depend on how deep you pockets are

make sure the company reboring the block have the experience in doing them and the right equipment.(the right torque plate)

there are very few engineers that do and they will try to hone the block out,

i found out to my horror, my local engineers said they could do it, and honed cylinder 4 out a tiny bit off center and the block lasted a few thousand miles before the cylinder went oval.
