3.0 to 3.2 SS upgrade

Other than buying new parts costing me big bucks are these options viable?

1) buy new Mahle jugs & pistons for approximately 5-6,000
2) buy used 3.2 mahle pistons and have my existing 3.0 jugs bored over size & electroplated
3) buy used 3.2 jugs and get them electroplated. Will I have to re-machine my 3.0L block to accept the 3.2 jugs


Thanks


David

Looking for more power? That was fast. I'm in the same contemplation boat.

The 3.0 cylinders won’t bore to 98 because of the sealing ring becomes too close to the bore.
3.2 cylinders can open to 98mm. You don’t need to cut case as cylinders are the same spigot
Alternate idea
3.2 crank and rods and a good set of Mahle Carrera Ps will slide into your cylinders
Three L crank and rods have excellent value to defray crank costs.

I thought the benefit of a 3.2ss was the 3.0 stroke with the larger bore giving it a rev happy nature. I may be wrong, i'm mostly an idiot.

hmmmm, no replacement for displacement. Wonder what the cost difference would be, would be cool to see a kind of chart from a 3.0 rebuild to a 3.2SS build to a 3.4 build

Call EBS Racing. I bought the 3.0 plated cylinders and JE pistons. Should have bought the 98mm bored out cylinders.

I totally agree with last posts = if u r increasing displacement for what ever reason, why not maximize your value on the new parts going to b using...
“ there is NO replacement for displacement “...........

On a 79 SC - I found a good used set of Max Moritz P&C, 98mm 9.3 compression (going up from 8.5), then added 964 cam grind, aluminum flywheel, SSIs and M&K 2 in 2 our exhaust, still have CIS and I assume I went from 180Hp to a little over 200hp, but the torque is unbelievable. Built it up in 2010 and have been autocrossing it ever since. I love the car.

If I couldn't get the Max Moritz I had planned on getting a set of 84-89 Carrera Jugs and sending them to EBS for enlarging and plating and matching to J&E pistons.

i went 98mm replated carrerra cylinders from ebs and cp pistons, twin spark EDIS and SSIs/Dansk Sport I am happy with the performance. Still not 'fast', but sufficiently better than stock that I finally stopped having negative thoughts. I chose to stay w/stock cams which I am happy with for road use. I wish I had gone with 9.5CR instead of 10.5 because of the increasingly limited supply of premium gas here. Now I need to carry octane booster on trips. But apart from that I am happy with the compromises I made. Swapping crank and rods, ARP bolts needed. Will the CIS handle that ? Big port heads or not ? What kind of exhaust to use with 3.4 ? Much larger scope than 3.2SS

I find myself spending a lot of time reading and learning about adding a turbo.... just so much gain for the money.

I built my 3.0 into a 3.3SS using 100mm Mahle pistons and LN Engineering "slip fit" 100mm cylinders. Added 964 cams, Carrera big port heads with twin plug crank fire ignition and an early large port CIS air box. Pistons are about 10.8:1 compression. I think I paid $4k for the cylinders, about $1.2k for the pistons, $1.3k for the Electromotive ignition and a couple hundred for a set of clean 964 cams. One big advantage to building a 3.0 engine is having the stronger rods and rod bolts compared to the 3.2 engine. I think my engine is making about 250 hp, maybe a bit more. Pulls strong up to 7500 rpms where I have the ignition cutout set. Total cost to do the engine was in the $10-$12K range.

Where did you get this done for $12k?
