Grape's 20/20 build thread

[GrapeBandit]

Contents: 20 valve true 2L AEB stroker build
I am going to document build with as much detail as possible and keep it updated as it progresses.

I had no intentions on doing this, but I had some recent carnage


wiped out all my pistons and all 8 exhaust valves.
so did i smash my pistons with my valves? or did I smash my valves with my pistons? either way, the damage the done.

the culprit: sheared keyway on the crank timing gear


this is not the first time this happed on a 1.8t I owned, but it will be the last. im going to dowel pin my new crank timing gear into the crank.

before:

how it sits now:


Since this is a spur of the moment ordeal and a big surprise to me, I really dont have a turbo picked out, so I will run this on a measly K04 for the time being.

parts on the way:
92.8mm forged ABA crankshaft.
83.5mm supertech 8.7:1 pistons.
supertech inconel exhast valves.
144mm scat rods w/20mm wrist pins.
all applicable bearings and a full engine gasket set.

Sucks that a build had to start the way it did. Ive thought about picking up another complete AEB motor building it and possibly do a Precision 5857 turbo. I would just be upgrading the rods, valves, springs and cams, no stroker kit.

you aint shitting. I had zero plans on building this, as I have special parts for another build laying around until I had the funds to go crazy. now I have to build this shit, and make it worthy. idk if I want to BT this, or rock the block until I have enough money to finish my "special" build, and sell this block. I dont need or havent planned on having to BT blocks

efr and full-race mani...if only i had the 3k+ that i wanted to dump into a car i dont drive.
Good luck with the build!

[rodgertherabit]

Oh, im just gonna rip this apart!!! Grape style

Seriously tho! congrats for taking the plunge! Im thinking about selling the gtx, its no efr but its still nice. ;-P

no full race mani, I can get a nice custom one done for around a stack.

you can rip this apart, idc, I dug deep into many other members. is it my turn now? lol

the full race is machine welded with a lifetime warranty for $164 more then a stack doe

what is this mani you speak of?

[coolgraymemo]

I've thought about an 18/18 build.

18 valve true 1.8L AEB build.

18 valve, huh? lol

Going to take two out for weight reduction.

Going to take two out for weight reduction.

thats hot! hopefully they are intakes

sent my intermediate shaft to FFE today to machine for #4rod clearance and balancing.

[MetalMan]

That coolant tank wants to be replaced so it won't look out of place in your white engine bay
Will be watching this!

ahh shit. I have 3 of these coolant tanks in the garage. im actually going to paint it black instead of buying a new clear one haha

Pfffftttt, pnueb

silly ass! ! !

am I a pneub, noob, or a newb

[RoadRage]

I need to find a cheap spare engine. I'd love to build an engine, but I need my car to be running.

This should be good. Subbed.

do you have 06a or 058?

[RoadRage]

do you have 06a or 058?

I'm 058.

[GrapeBandit]

I'm 058.

so you can find a cheap blown engine somewhere for like $300. keep it in the garage and build it slowly

[Seerlah]

Just busting chops, Vince

Waiting to see you get back to something better than your old B5 A4 with the GT35R. What are your HP goals? I know someone selling a brand new (rebuilt) Comp Turbo 5858 triplex for $900 I think, if interested. He has two of them.

its hard to outdue a gt35r 2L b5.

I dont have hp goals with this car since tbis build is just happening due to a faulty crank timing gear

as for Comp turbo, ill pass. its hit or miss with that company.
I will rock my K04 for now while I decide what I want to do with this engine.

[Seerlah]

And I know you are not a noob. Most likely know more than me (not even joking). But then again, I only know what I know.

[GrapeBandit]

lol@ninja edit

I am a complete newb when it comes to the 058 block though. the 2L I built for my last car was 06a, and the few others I helped out were also 06a. this 058 seems like a lot more work and BS to accomplish the same thing you can easily do with 06a, hence my next "special" build has alh(06a block)

[redline380]

ooooooooo, awwwwwww.

Sign me up!

[GrapeBandit]

ooooooooo, awwwwwww.

Sign me up!

thats a long way off, its what I have been saving for. now this happened and threw a monkey wrench in the whole program lol

Wish i had the bucks for this man great idea though!

I want to see a bw 7163.

[RallyeBourne]

That blows big testes. But I'm glad I can watch you do this. I'm going to pull an 06A block from a yard soon and stroke it out to 2L. It'll be nice to watch you do this first.

He's stroking an 058, so a little different. The 06a is actually easier and less money involved.

FWIW, the motor in my sedan came out of a junkyard for $200. I love junkyard motor builds.

[RallyeBourne]

Oh, I missed that point. Oh well, still be nice to watch an engine build.

Motors from my local go-to are $287.95, but there is a 50%off sale coming up soon. That's when I'll strike.

[viceprp]

Just do a nice DD, 2.0 GTX2871.

[B5A4coastie]

That suck man, I'm sorry to hear you have to do this work before you're ready. The timing gear key snapped on your other crank as well?

I also have the 058 block that costs an arm and a leg to modify. I understand that you're making this bullet proof, but why swap out your crank if you're not looking to stroke it? Shouldn't the AEB crank handle the added stress? I did some research and saw the size difference and forged, ect that the ABA offers, but is piecing this together really that much cheaper than buying an IE kit? I already have Scat rods, so would larger pistons be adequate if I was to aim for the 2.0?

I want to see a bw 7163.

haa. im sure everyone wants that turbo, myself included

Just do a nice DD, 2.0 GTX2871.

like i said earlier, i have no clue what im going to do about a turbo. just going to build the block and rock it k04 style. turbo upgrade most likely a few months out.

That suck man, I'm sorry to hear you have to do this work before you're ready. The timing gear key snapped on your other crank as well?

Yes, it does suck, very badly, especially since i did a full timing belt service, head gasket, full engine gasket, clutch/pp/flywheel on this car about 10,000 miles ago. everything was still fresh.

the keyway in the crank timing gear had snapped off in one of my other 1.8t's back in like 2008/2009. so needless to say, me and crank timing gears no longer get along, i do not trust them thats why this one will be dowel pinned

I also have the 058 block that costs an arm and a leg to modify. I understand that you're making this bullet proof, but why swap out your crank if you're not looking to stroke it? Shouldn't the AEB crank handle the added stress?

the AEB doesnt really cost an arm and a leg to modify, its actually the cheapest to stroke out. i decided to stroke it because the engine is all apart, so what better time, right? i needed new pistons anyway, so for the additional cost of $135 shipped for the forged ABA crank, and the $75 to get my intermediate shaft machined, it was worth it to pick up an extra 10% displacement over stock.

the stock aeb crank can handle anything you throw at it. i have yet to see anyone break a cast crank on the b5 platform.

I did some research and saw the size difference and forged, ect that the ABA offers, but is piecing this together really that much cheaper than buying an IE kit? I already have Scat rods, so would larger pistons be adequate if I was to aim for the 2.0?

piecing together a kit on your own would save tons of money, not sure how these shops charge as much as they do for shit and get away with it. i didnt see a stroker kit on IE for the 058, just the 06a, but just to give you an example, ill break it down.
Cheapest IE stoker kit, if you want to call it that since it doesnt even come with a crankshaft
$1349.99 for the basic kit which contains: pistons, h-beamrods, crank timing gear dowel pin kit, and crank trigger wheel. great kit, NOT!
http://www.performancebyie.com/integ...e-kit-8-5-1-cr
if you want to add in a crank from IE, you need $2000 to get the above mentioned w/crank. what a ripoff.

my piece together kit so far: ODBI ABA(forged) crankshaft $135 shipped
New Supertech pistons(83.5mm)/rings
New Scat 144mm h-beam rods w/ARP2000
New Supertech Inconel exhaust valves(8)

if you want to make a 2.0, you would at least need a 92.8mm crank(cast or forged), and at least 83mm pistons

[redline380]

the AEB doesnt really cost an arm and a leg to modify, its actually the cheapest to stroke out.

I disagree with this statement. All an 06a takes is pistons and an AEG crank which can be had for $75 and up. 058 usually need IM shaft machining, making them cost more to stroke.

true, but you can source a forged crank for the 058 for the price of a cast 06a crank. forged crank is not needed, but its good to have. if you want to use fsi crank for 06a stroker, it will cost more than doing a forged crank 058 stroker

I misunderstood the definition of "stroker" I originally thought it had to do with the length of the rods, but it's the crank (distance traveled from TDC to BDC) that would actually determine the stoke... Every day is a school day.

Now by increasing the stroke would decrease the gap between the piston and valves, how will you combat that? 92.8mm (2.0), 86.4mm (1.8). That's 6.4mm, will a thick head gasket be required?

In order to see the full benefit of the stroker, do you need cams to allow more air movement? What about advancing or retarding the cams since the stroke will change?

Edit: I just found a few answers here: http://www.eaglerod.com/index.php?op...d=40&Itemid=25 Seems like one hell of a headache.
