OBDI or OBD II?

lol thats it but yeah so i donno i may need to get the pistons custom but the ones on the G60 or other 2.0s don't need to be done???

They all Need to be done except with a PG block you can use the original stock 1.8T rods and pistons.For the 2.0 Applications I recommend giving Rodney Huss (rhussjr) a Buzz as he can get JE pistons for the 20V fr around $550US in 83mm bore.You can use the AEG conrods for the time being and if in the future you feel skeptical about them,you could always have Pauter make a set to match your crank and JE pistons http://****************.com/smile/emthup.gif

Re: (Wizard-of-OD)

what about double stanking the gaskets since i'm turboing it and will have a boost controller i can upp the boost and the compression will still be nice with added power and more valve clearance. i donno if it'll work but meh. or what about a thinker gasket

the CR is allready "low" by most standards when placing a 20V head on an 8V block.Double stacking will drop the CR down a point bringing it to about 7.5:1,Maybe lower.The stock 1.8T has a CR from 9.3:1 to 9.5:1.I didnt know thinner HG's were available...got me there.
I would suggest the pistons dude.Honestly http://****************.com/smile/emthup.gif

Re: (Wizard-of-OD)

aight thats cool but now that i looking at the ABA block with JE pistons i don't see that hes got em modified for the 5 valve i looks like its just flat up agains the top of the block.
do you know how much the valves open anyways like i'm trying to figure this out and your suggestens seem to be the best way to do it but there could be others i'm just trying to figure it out cuz i wanan do this it'll be like a mk 2.0T this way

Early AEB's had an external water pump and followed the old style of VAG Blocks.
and ABA is far from week my friend.You will have an advantage of a higher rod ratio when comparing the ABA to AWD/AEG
ABA has a rod length of 159mm whereas the AEB has a rod length of 144mm.My advice is to at least change the pistons.You wont go wrong http://****************.com/smile/emthup.gif

Re: (Wizard-of-OD)

ABA is from a mk4 isn't it or am i stupid and thinking wrong
ugh i'll just swap a 1.8T its less hassle and cheaper and then i'll get it bored out and put 2.0 forged pistons if they will fit

Good Luck,Post up your findings http://****************.com/smile/emthup.gif
Just a bit of Longitudinal mounting Reference for you Passat 1.8T guys/Audi A4 1.8T guys in terms of engine mount brackets for the ABK/AEB or ABA/AEB set-up

Re: (Wizard-of-OD)

ABA = Mk3 engine
It wont bolt into a Mk4 chassis because it doesnt have the pass side engine mount mounting points.
AEB will bolt into a mk3 no problem since it uses an older style block with the exception of extra oil drain holes.

then which is the 20v head that will bolt up to a mk4 AEG is it the AWD

Re: (Wizard-of-OD)

Like Ive told you before, dropping a 20v head on a mk4 2l block seems pretty simple. You really only have to swap to a custom pistons, 1.8t headgasket, 2l timing belt and engine management to run it all. All 20v heads are the same at the deck surface. AEB's have larger ports and AWW/AWP engines have variable cam timing.

If all goes well I will be building my buddies AVH into a 20v engine and have more info on the conversion in a few months.

hmm but which one have the 5 oil returns and which is better and is used on the 2002-2004 1.8Ts with 180 hp

AEG follows the new style of Blocks with an Internal waterpump.Only 1.8T engine to follow the old style of blocks was the AEB which was a modified old style external water pump with 5 return oil holes.
So physically a 1.8T 20V head will bolt up to a new model 2.0 block without any modifications.Just need to work on pistons. http://****************.com/smile/emthup.gif

Re: (vwpat)

well the AEB is 9.5:1 compression, i'm guessing with some porting and good tuning, the g60/lysholm at lower boost you might be able to rock out 10:1 or 10.5:1 without blasting the motor apart.
remember those guys hit 240wft/lbs at 21psi peak torque at 14.5:1 air fuel ratio, so those are some damn well designed combustion chambers to take that abuse.
i'd probably say raise the compression if all you got is a g60 to blow it

Considering Im wailin out 38 degrees advanced at 6500 on 11psi in 100 degree weather on 91 octane, Id agree http://****************.com/smile/emthup.gif Ill have some numbers here shortly. Im lookin to bump the compression to the 9.7ish range.

Because the motor puts out more hp stock doesnt mean its any better. They run more boost, a better flowing turbo and have variable cam timing. The AEB is actually a better engine since it comes with forged crank, rods and a big port head. Things the transverse motors wish they had.

AEB = German

AEB Crank = 86.4mm Stroke
AEG Crank = 92.8 mm Stroke
the 2.0 comes from the Crank guy....
