Compatible Pistons are available trough either Vitesse or Chris white but must be made so it takes a while, mathle or wossner pistons with the right coating seems to be the safest bet.

Depends on how radical you want to go.

Crank 1500
Knife Edge Mod for Crank 1000
Pistons 1000
Rods 1200
Studs 400
Windage Ports 400
Head Mods 1000 and up
Turbo 1500
After market ECU 1500

Not difficult but it can be expensive if you are starting from scratch.

The 3.0 l you have all of the above plus a donor engine and mods to your 2.5 l head to make it work. The 3.0 l block has siamesed bores and more support around the cylinder. The 3.0 l will make more power with less boost. Just remeber the old saying: "There is no replacement for displacement."

Vitesse stage 3 and 26psi??? Love it!!!

And glad to see one more performace car owner realize the cost/benefit of running E85.

rlm328

I don't think anyone has any problems with E85 other than availability. Most tracks only allow you to carry 5 gal. jugs and at 5 mpg at the track it only takes a day to butrn through 30 to 40 gals. As my ECU would need to be mapped for one or the other. The benefits of E85 are huge. But when you are at one of these tracks in the middle of no where it is not fun trying to hunt down place that sells it. I am in high hopes that its availability increases in the near future.

Actually you might be suprised that a lot of people, even on RL, still think it is just a band aid for a poor tune, makes you run too lean, will eat fuel lines, etc .etc.

I have seen a fair amount of resistance to e85 even in the performance car crowds. Yea, in the NA world it is not really needed but in the forced induction world I think it the new white bread. lol

Cheaper than 93 and equates to 105-110 octane.

Do you have a source for e85 in SoMD?

toddk911

Nope!

I check the E85 locations often. Doesn't look like there are any plans for E85 down here anytime soon.

I guess I will just have to instal my meth inj system.

Well 26psi can not be done with out issues . I had problems with fuel delivery and spark . The cap and rotor does not perform to well luckily i have a fix for that in the spring as well as new fuel pumps from SX performance.

What did the shop quote you for the engine swap if you can say? I have had a couple of quotes for $2500 for the swap by reputable shops. I know many have done their own but my garage is too cold and wet in the winter and I don't want to miss any track time so I will most likely have a shop do mine.

Dougs951

So its been 48hrs, wheres this 2.8L?

toddk911

Well the 2.8 is safely in the hands of the shop. I will get my car up to them Wed and they will probably drop my motor and get them both on stands and then swap out my turbo, injectors, etc. onto the 2.8. As well as pulling my clutch disk and PP to have sent to South Bend.

There are a few other things being done during the swap, but the ball park cost on the swap itself is $1,200-1,500.

I got to meet Randy (piperporsche) and another guy from the shop I had not met before and we toured this new location they are at and had some nice cars in there, to include a Carrera 4 with a supercharger kit installed.

toddk911

Sounds good. Keep me posted.

I plan to keep it about 1 bar at first for a few months and make sure all is well, then up to 18-20psi with Rouge's C tune which will be making plenty of power. lol

Then maybe by summer have my water/meth injection installed and work with Rogue again and datalogs/knock counts and ease up the boost to 22-25psi with proper meth injection.

Adonay

Theoretically if 15psi is max you should go with our cars on 93, the added octane in the E85 should allow you to safely upp the boost by 6psi or so they say. That would be something like 20-21psi. By adding more aggressive timing you should lower the max boost . I believe the amount of fuel going through the engine cools very well.
Safe to say i am beyond what can be considered safe but have yet to find any evidence of detonation on the internal parts.I run a widefire gasket on a stock head. I do not recommend going above 20 psi as i have no evidence off it beeing healthy to the engine either.
There are also people who say they have been running 18psi on 93 for years with out issues, although that would not be me . Anyways anything above 22psi (E85) on our cars with a steady tune seems to bring the EGTs to new "Higher" levels. You may also look at colder plugs if running 18+psi. The cap\rotor\coil will start to struggle at boost levels above 20psi "datalogged" with E85.Make sure you get a 044 pump for stable fuel delivery so you don't get lean spikes at higher rpms.

My plan was to kill the engine and test were the limits are have not found them "yet" with E85. Engine is being rebuilt now after the oil pick up tube broke "on idle\cruise" and all looks fine. I have several sources for a 3L crank and rods and debating with my self if i should go 2,8. I wish you great luck with your swap and hope you share your thoughts. I think your 2,8 will be a blast to drive at 18-20 psi, i guess thats were your turbo work best as well. Be prepared to use allot of fuel with E85, MPG sucks.

rlm328

The 2.8s come into their own about 16 psi boost. For durability I would. Keep the boost under 18.

Friend of mine runs 21psi on Euro 98 unleaded (93 US) on his LR75 (2.5 engine), and he doesn't get much knock mostly thanks to a large front mount intercooler.
