Audi RS2 -94 Swe

[s0_big]

Yesterday i got some time in the garage for the RS2. Like i said earlier the head was refurbished by the last owner (newer) mounted. The lifters they didn't change though. As the car has about 240 000km on it it thought it was very stupid not to change them. I did have a spare head from the URS4 that i had brand new lifters in, so i dissasembled the head and took my new lifters to the ADU-head. I can' stand noisy lifters
Happy i changed them, there was some old burnt/lose oil particles under the lifters, the company that refurbished the head didn't clean them at all.

Head without cams/lifters:

Camshafts in place and alligned, caps tightend to 15Nm, waiting to get mounted, will clean the outside of the head a bit more:

Parts delivered to the painter yesterday. After some thinking and looking at colours I choose to go with a colour from Porsche called GT-Silber effect. On their cars it will be with shiny clearcoat. I don't want "shiny" so I went with a matt clear coat. Hopefully it will look good. Don't want to blast everything again


Today I sorted out some bolts and brackets thats going on refurbish. Will be yellow/gold galvanized as it was from the factory. The "aluminium" colored bolts is harder to get refurbished around here. So i think those will be stainless instead. Maybe I manage to leave them this week.

So, today was work day in the garage, i woke up a little late but i think i managed to do as much as i wanted to today.

The block was cleaned with break cleaner from dust and stuff since i clenaned it last time with brushes. Blew it off with compressed air in all channels.


Cleaned the oil jets for piston cooling and installed them, loctite and 10Nm according to manual.

Bearings installed in the block and lubed up with assembly lube:

Crankshaft cleaned for the last time. Put some lube on the bearing surfaces and on the surfaces for the thrust washers:
45764-341a86858c8ce8e3e49efd65712198a6.jpg Crank installed with factory bolts, no need to change them according to manual. Torqued to 65Nm with oil between contact surface and bolts. Bearing caps should be intalled with bearing caps number (1-6) facing the exhaust side. Nr 1 closest to pulley side:

Torqued 30Nm+90 degrees according to manual, oil the surface between nut and conrod:

Conrods installed with "lugs" pointing towards pulley end as manual.

Pistons installed, valve pockets facing intake side. Hopfully i will not have to see them ever again after i put the head on

The ADU head nr 002094 , it should be just PNP as it is overhauled by the last owner. New valve guides, sealings, grinded seats, valves and resurfaced. The lifters is as far as i know the olde one's. But i will take my "new" lifters from the AAN head that i had for one summer on the Urs4. It would be stupid to run it without changing them. I hate noisy lifters

That's all for today. On monday i will leave the aluminium parts that i glasblasted to the painter. Can't wait to get them back so i can continue with the assembly.. Then it will start to look like an engine again!

... How do you delete posts?

Do you need the orange hose between the turbo and IC? If so i have a fully funktional one i dont think i am going to use ever.

I think i got all hose in the kit from do88, but thanks for asking =)

Some parts i ordered arrived today! Missing hose between airbox/turbo. Clutch disk and the little extra water cooler. Tomorrow i will hopfully be able to assemble crankshaft/pistons with the block

This is a nice catch! 10 years back I was looking at RS2's from the swedish Blocket site, and they was as low as ~10k€, but hadn't the money at the time.

Can't you just grind off few gramms with an dremel tool to get the weight match? From the inside of the piston..

Yeah I got it for a decent price as the engine was out and dismantled.. otherwise I could never afford a RS2. Yeah I could do that. Will think about it. Hopefully I can find time to assemble the block during this week. Put a big order off stuff yesterday as a early Christmas gift to myself.

All new stuff:

Extra water cooler
Water thermostat
All water hoses
All pressure hoses
Hose between Airbox/turbo
Engine/gearbox mounts x-line from cp-s
Sachs pressure plate "724" for dual mass flywheel
Sachs reinforced clutch disc
Sachs throw out bearing
Billet water connection back of the block

Hopefully I will have most of the stuff to assemble the engine now. The other big thing I have to buy is a refurbish of the turbo or an exchange one. The compressor wheel has some damage unfortunately.

Hopefully I will have it running before next summer

Sure, in a perfect world it should be 0g. Anyone weight the difference of 5 original pistons from a stock 5 cyl engine?

[_ShurikeN]

Good weight difference is not more than 1 gram.

[s0_big]

Yesterday i had a quick visit to the garage to measure the weight difference of the new vs the old piston. It was about 5g, The difference is not much, so i think it will be allright. Hopfully i can assemble the crank/rods in the weekend. What do you think, is 5g to much difference or is it nothing to worry about?
