i have a 2.7 & im wanting to make it bigger with out spending 3000.? does anybody have any good suggestions.any info would be very helpful.thanks jim

swap it for running 3.0 and sell your core. Look for a motor that has already been upgraded and documented. Rebuilding a 2.7 into anything bigger is going to be tough for under $3k. Good luck!

Steal a SC..............

Or get one for a steal. Agreed that building the 2.7 is not the way to go. Find a good deal on a 3.0L and do a swap. Hopefully your core will be a solid one and help you recover some of the cost. A refreshed 3.0 is going to be hard to get a good deal on. The ones that are a little tired are those that can obviously be had cheaper.

yes but let me explain i have a perfect 7r case that has alot off nice machine work done by olies this case has never pulled a head stud,i have a realy nice set of rsr spec heads(small stud spacing) 964 pump s rods olies did all machine work ive got to much in it to throw away im looking on a deal on pistons and cylinders?

Jim,

Andial 2.9 conversion set is around $5 less than $3K ...

EBS might be able to supply some reconditioned 3.0 cylinders and JE 9.5:1 pistons for a little less ...

Those are about the only real option, unless you expect a windfall estate auction, or something of the like!

Oh. Well that makes a big difference! Gotta tell us that up front.

sorry about that, I thought your 2.7 was a used up core.

For $3k, maybe custom J&Es and cams. What induction are you using?

birel23 · 01-29-2004, 06:45 PM

mfi manifolds with 40 pound msd inj. and a tech unit from electromotive,intercooler on top like 934,twin 996 turbo's with 1&5/8 headers.

Doesn't JE make their own 2.9 pistons and cylinders now for something like $1900? That's what I was told anyway.

birel23 · 01-30-2004, 07:45 AM

that is the first i have heard that they make cylinders ill call today thanks ill give that a shot thats more in my range!

What kind of heads/headwork is need for the 2.9 conversion? Is twin plug necessary?

birel23 · 01-30-2004, 05:26 PM

andial says its not a nesesity but im twin plugging mine cause of turbo.i guess it depends on combo and useage.

birel23:

The Motor-M says $3k for the kit and the case needs to be open. Any idea what other mods they need to do? Open up the spigots? etc... have you heard / seen performance on this kit?

I ask b/c I have a "spare" '74 CIS 2.7 that I might upgrade.

Thanks.

the kits i have seen have studs cylinders/pistons rings ect and all say machining case. i just want the cylinders,but i have not seen them sold seperately. i drove a car before and after the andial kit was installed. it much better torque.it felt like sc then. i am worried about the case getting to weak. i race mine. i have never had a problem with it yet. i have never even pulled a head stud & i run 1.2 bar of boost.my case has been align bored & has had oil update& dilivars upper and lower.all the kits i have seen are for non turbo applications that is why i just want cylinders & then ill have pistons made or find a set of good used ones.

Did anyone find out if Tyson's post was correct? It's too early to call JE where I am.

I have a 2.7 7R case with 9.5:1 JEs and Mahle jugs and MFI. Engine is currently apart for re-build.

Do you guys think the 2.9 set from JE would work with my heads or am I going down the road of no return? I could sell my 2.7 JEs and jugs. Upgrade would be around $900.

Oh. Almost forgot. I thought Bruce Anderson said that the wall thickness of the 2.9 cylinders was too thin. Are these custom cylinders???

Cheers,

Tristan
