RichLV's UrS4

[hunker7]

I think exhaust is a very personal thing.

[RichLV]

I like it. Some of my friends don't. I usually drive with loud music since my audio system is pretty good and I like loud and shouty cars in general.

[hunker7]

How is it under normal driving? Not too loud?

[RichLV]

Oh I think you'll love it. It's a very raspy and powerful sound. When I'm driving, I can be heard like miles away. When I was picking up my GF, she was already waiting outside because she heard me inside the house. And it's a pretty unique sound, haven't heard any other cars or 5-pots sound like that.

[hunker7]

You shall make a video when she's running. Want to hear that

[RichLV]

It's 96 db(A). We have a max of 85 here.

[hunker7]

How loud is it?

[RichLV]

Somewhere I do, but it's nothing special. OEM downpipe with the T piece cut and welded, and a straight 60mm pipe afterwards. I'll go for a 76mm downpipe and exhaust after the turbo upgrade.





It's not a solid piece for a reason, I can't pass MOT with my FK-Automotive end muffler, I have a spare quieter one which I swap over.

[Kieron20V]

Have you got any pictures of the exhaust you made?

[RichLV]

Finally got an assembled bottom end. And I've disassembled it right away.


The crank is out and seems fine. There were some wear signs on both main bearings and rod bearings. The block and crank will go to a shop for wear check and grinding if needed.


OEM rods will probably be sold, since I'm going for an upgrade.


Pistons also seem fine, a bit of cleaning and they'll be like new. I'll get new wrist pin retaining rings. A question though, do I need new piston wrist pins? I couldn't find any part number on those. I suspect they only come with pistons.

Nice Car!

[RichLV]

So I went and took off the head.


^ this is how my pistons look like. The car has been on a pretty generous oil diet.


^ manifold cracked in one of the usual places. Doesn't seem to be going outside.




^ and I've got a unicorn you guys! Crackless head. It's a very early head, 1992, engine build 3390. Aaand it's crackless... Happy as hell... It has bumps and bruises and scratches on some of the surfaces inside, probably because someone used screwdrivers there. Two of the front valve cover bolts cannot be tightened, the thread has been stripped. Basically nothing major, all fixable.


^ only Cyl 3 has some sort of piece broken off. A very little piece. I think I shouldn't look for a new head just because of this one.


^ A piston close up.

The manifold will probably go into the bin or something, I'll fit the RS2 one. Cams are in very good shape. Though I will hunt for the 7A exhaust cam. Checked the cam pulley sprocket, all good.

Question. Can I stay with cylinder head bolts or should I get the ARP studs?

[RichLV]

It's either the oil pump (which I highly doubt) or the bearings. Most likely the bearings as the pressure drops a lot when car gets hot. Dude who I bought it from probably lied about them being replaced. I'm suspecting that's why it has a 3B block, they killed the original one & strapped on a tired 3B just the sell the car.

I'm gonna get the head off today, to see if I need to look for a 7A.

Yeah, it's gonna milk money like a motherf**ker.

[macspring]

Would agree with your plan.

Assuming you tear down the current tired engine, if would be interesting to see what is the cause of the low ol pressure, assuming it is not a little bit of everything.

Good luck on the bread and water for the next while.

[RichLV]

While waiting for the replacement turbo I changed the action plan for my UrS. I have bad oil pressure when the car heats up, only 0.9 bar on idle, and barely over 2 when at 2000rpm. With that pressure I'm gonna kill another turbo and the engine in general. So I'm starting to rebuild it. I already found an assembled bottom end, gonna get it and start working on the engine.
