2.7 Rebuild.... Advice?

[Fishcop]

Thanks Wayne, that's just what I intend to do. I'm just having a bit of trouble locating someone who can re-Nikasil barrels here in Australia.

Plating isn't cheap and I wouldn't plate the 2.7 Alusils cylinders unless they were like new. The cylinders tend to wear in an oval pattern. If they show wear I would bore them out to 92mm and then plate them and get a set of 92mm JE's to give you a 2.8L motor. Plating is about $1200 for the set and the pistons are $1000 for a total of about $2200. You might also consider a new set of 2.9L Mahle P+C's for a few hundred more.

The cheapest alternative is a new set of Mahle 2.7RS P+C's. You can pick these up for about $1400.

The 2.7 RS are forged, not cast pistons.......Ron

[Bobboloo]

That's a good point Ron. Are the 2.7 Euro sets that are forsale these days from people like EBS forged like the original ones?

I can only imagine that they are.

I bought my 2.7 RS forged from EBS in '98 for about $1600US

I'm sure we can beat their price easily on any available piston and cylinder sets...

I've noticed a couple of sets on Ebay for around $1700 USD, is this good price, or can I do better?

You're right Cam, 71.43 today

[Fishcop]

You were too fast for me Wayne! Okay I'll test you... What can you do a set of RS P&Cs for?

Cheers

[Wayne 962]

I'm having Tom check this right now...

I mentioned the info as a data point.. I always give PP the 1st shot at my parts, except the wierd ones. I didn't know PP existed in '98..
no dis-respect intended.......Ron

For the BBS, we can offer them on special for $1599. This is brand new, and applies only to the two sets that I have in stock. If you want them, then give Tom a call at 1-888-280-7799x221. This is a below-normal-margin thank you deal to people who have contributed to this forum. This is the forged, Mahle, 1973 911RS 2.7 Piston and Cylinder set.

What happened with the 2.4t uprated to S specs and Webers that was for sale? Did you get to look at or drive that motor. I believe that it still for sale.

[Fishcop]

I don't believe there was anything wrong with the 2.4, It was just that I found a complete 2.7 for half the asking price of the 2.4

ber911????

Wayne, thanks for getting back to me on the RS pistons. I will make some enquiries in relation to additional import costs. What do you think the shipping weight/price would be to Australia? I'd phone you but you lot are asleep when I'm awake!

Nope, I'm awake. I'm not sure of the shipping costs - where are you located? Probably about $100 or so - we won't ship this Internationally without insuring it...

I had a set of P&C DHL'd from California for slightly more than what Wayne quoted (US$128). They arrived in only a few days.

(disclosure: bought before Wayne started stocking the P&C - I would have bought from him, of course)

[RoninLB]

I was using the 2.7 RS 8.5:1 with stock CIS.
and not a problem with getting a good mixture and smog numbers were great.......Ron

John - Some encouragement for you: I dyno'd my new race motor on Wednesday, the base specs are:

2.7 litre 7R case - hpc coated
Carrera RS ports/valves (with some massaging) (36/38 I think?)
10.5:1 ARIAS pistons - short skirt, hpc coated
GE80 cams
Early heat exch's
Single big outlet monty exh
40mm Webers

Made 228hp basically untuned and running rich.

Now just have to sort out the MFI pump, finish the dual distr and connect up the second set of plugs...hoping for 250hp

Cheers - Ryan

ps: the GE80 cams are great - no probs at all driving on the street

[Fishcop]

Ryan

Your engine sounds quite similar to what I'm building:

7R case
S cams
Webers (34 venturis)
RS P&Cs (8.5:1)... or something similar
Early exhaust (with the heat exchangers removed)
Big Mili Miglia silencer (single out)
Heads are standard 2.7 with some mild porting

I'm chasing 200 (reliable) hp

What's the story with the HPC coatings and what sort of cost?
