So rather than keep looking for a shorter R&P I will embrace what I have and build a killer 7000ish RPM stroker motor with parts I already have or are readily (cheaply) available. I currently have a short deck 220mm 2l with 144mm rods, 92.8mm stroke, I also have a TDi crank with 95.5mm stroke, couple that with the (free) ABA tall deck 236mm block and its 159mm rods for roughly 2.1l with a better rod ratio, only added cost would be to lighten the heavy TDi crank and clearance it for the oil squirters. 13:1 Pistons, lumpy cams and ITBs, ABF clone on steroids. Gotta love VWs, tall-block 2.slow 8V block and rods, TDi crankshaft, 16V head all bolt together without to much crazy fanfare. 51mph first gear will be interesting, not that I have to shift that late...... Power means nothing if you cannot control it! |

Not sure.......VW ran a lot of years on this exact gearset, and regardless of FD if you want 105-110mph for a top end 1st is pretty tall. I'd prefer to run well below 8000 and have a lot flatter powerband, if I go with that motor combo I will be able to lug it pretty low. Hopefully the syncros are beefed up too.

Some very very fast people ( in what used to be a big powerhouse in rally) have been known to just leave out the bronze synchro rings "so you can shift with no clutch while Left Food Braking. Just pull that lever---it'll go in" Imagine my shock when I took the lid off my first real rally box and found no synchro rings...

Either way, your ratios are much better than what I can do on a budget with OEM USDM mitsu shit from my car's era. They look evenly spaced which should be nice, no huge jumps. Lastly, I'm not speaking from stage experience- so take anything I say with a big grain of salt |

Gear ratios look like 2nd is about the same as a production car 2nd but 1st is taller so actually useful, and 3-4-5 are smooshed together so that they are all useful instead of big drops. I like!
If you wanna see weird ratios, look at the 6 speed box Mazda is putting in the new Miata. 1:1 top gear, 1st gear is 5:1, and they run a sub-3:1 final drive. Probably to get driveshaft speed down or something, or make 6th gear super-efficient. 1st 5.087 2nd 2.991 3rd 2.035 4th 1.594 5th 1.286 6th 1.000 Reverse 4.696 Final Drive 2.866 But I see it and think, hey, remove 1st and 2nd gear, that looks like a really sweet 4-speed box.

No dice , it's 16V, I don't think I'll waste any more time hunting, the only 16V 4.20 I found is in Kenya and is $1500 plus whatever it costs to get it here. Power means nothing if you cannot control it! |

Is the diesel 4.25 AVX R&P 8v or 16v splined?

8V, same as the 3.94 ACH I have, which would be ideal. If I get a 4.20, no stroker would be needed/desired since I would likely chase 7600ish. Only reason I am looking at the stroker is that it would be pointless to go much past 7000 with the 3.67.
Oh and regarding the crank failures I remembered that is in the short deck height blocks (220mm) not the tall block ABA/ABF mainly, back before the tall deck it was almost impossible to keep a stroker alive. Likely due to a really shitty rod ratio side loading the crank. The rod ratio in a 95.5mm stroked tall block with the 159mm is better than the factory 220mm deck 2.0 92.8 stroke with the 144 rods. Anyhow back framing bulkheads in my basement in prep for drywall. Power means nothing if you cannot control it! |

I am a dealer for Overland/EuroSpec Sport......could do 90x84 if I really wanted, just not much meat in the walls left once you bore it that much. They have an all aluminum 130HP 2.0 from a Passat as well brand new which might be interesting, although not that much weight savings. 8V as well, only 16V FD from factory was the 3.67. My other option is to get an MTS 1.43 4th and then an 8V FD in whatever flavour. Or I buy a diff and button it up with some new bearings and call it good. Build a somewhat suitable spare out of my remaining 16V trans parts and the ACH that is in the car now. Bonus on the Gemini kit is that they use a different bearing style that fits the standard retainer that will make the trans a lot easier to take apart quickly if I ever want to change angles or preload. It's a standard FAG bearing doesn't look custom, I'll post the part number next time I open up the box. If I'm not mistaken Derek Bottles ran the exact same gearset for many years and seemed to have done quite well so here's to hopin! Power means nothing if you cannot control it! |
