I am sure it will work Rage. I was thinking you didnt want to stroke the motor because you will make a high reving motor with that bored 2.5 Are you going to do any work to the crank, flywheel and what kind of rods will you use?

Luke

you gonna bolt on a 62-1?

Rage, I also want to say that it looks like you are in the process of building a very nice engine!! Many of us are looking forward to hearing about how well your new engine performs. Are you sticking with the stock 100mm bore? Or, something different?

And, I am wondering if you wouldn't mind sharing some information about the sleeves that were installed, such as:

1. Who is the manufacturer? Are they the Darton units?
2. What is the finished OD of the sleeves, both for the main portion of the sleeve and the top flange?
3. What size interference fit for the sleeves was used? I am guessing somewhere in the range of .003" to .005". Can you confirm?
4. What temp was the block heated to before inserting the sleeves?
5. Were the sleeves put in a freezer before installing into the block? Did they need a final chill in dry ice?
6. When the sleeves were installed, did they just drop in? Or, did they require some pressing to get them in?
7. Were all of the sleeves installed at the same time (i.e. during ONE heat cycle of the block)? Or, was each sleeve installed by itself by separately heating the block and chilling the sleeves each time?

Sorry for all the questions . . . I am hoping we can take some of the "mystery" out of steel sleeving our blocks.

Best regards,
Jeff

Rage,

Are you bringing your 944 up this weekend? I assume that she hasn't had the transplant yet.

Rage,

I posted something about this grouting process on another thread. I am really interested in this stuff. Not because I would use it, but you are! I'm at a loss why. Did you research the use of this stuff? Who told you it would do anything? Have you looked at your block and thought thro' what exactly you are doing? Seems to me all you have done is make the block heavier. Please tell me what this is going to do, how it will do this and what your engine builder is telling you.

I look forward to hearing your opinions.

Jeff,

To answer your questions, I suggest you ask the person who has your block. I cannot say if he would tell you, as this sort of info is usually keep secret. Its what makes their business one of the best. I know who has your block, because I am having them make all of the new parts etc for my engine project. Opinion or not, the experience there would be hard to beat. Look at the owners background. Ex F1 with 2 world championships, ex Cart/Indy, ex TRD, ex Porsche Motorsport. You picked the best place to have your work done. Not only because they know how, but because they do it all inhouse. I don't know many places that do.
Not only do they do their own work, they do alot of the special work for many well known tuners. A 944 turbo engine is probably the least complicated engine they do. From 904 4 cam engines to 962C and the new GT3R types, you can always see a wide selection been worked on.
There are times when you have to trust the people who are doing your work.

1. They're from John Anderson, not sure who makes them.
2-7. Ask John Anderson, I promised him the info would not be leaked .

Let's hope the weather is good, and air pressure is high! Hopefully our team is stong enough to win the cup.

You're right, the transplant hasn't happened yet. Make sure you stop by and say hi, I want to check out the Turbo S in person too!

As you know, the shop is called Performance Developments and is located in Costa Mesa, CA.

I just thought I would ask Rage these questions to see if he would feel at liberty to share his information. Since not everyone will be able to use Rage's shop (or even mine for that matter), we could learn from the specs that were used to build his engine. If his engine works out well, then we can assume the specs for his machining were pretty good!! If something fails on his block, then we would want to try something different. If we never know what specs Rage used to build his engine, then we will never know what worked for his particular setup.

A quick update... most of the parts have arrived, just labor now! I've decided to toss out the copper head gasket. My friend's M3 gave it a try, and he gave up after constant leaks and ripping the head off 3 times to reseal. Danno sent me one of his Ultimate Headgaskets with a 106mm bore.

Balance shaft delete parts :

JE slugs :


This should help my 400whp on pump gas goals :


Lucky me, we get 94 at the pump now .

Looks great Rage,

One small tip regarding balance shaft delete and oil leaks, in the above picture there is a roll pin looking thing where the shaft was, that pin and the bolt holes around it I had to use JB Weld to plug them up, caused major oil leaks until I filled them.

You might want to weld them before the engine is put together. Top and bottom shafts same problems.

Did you get the block from anderson? That looks like my old block I sent them.

rage2

Nope. I bought the "broken" block used locally for $50. The walls were scored too deep to rebuild. I did get the rest of the 2.8L gear from Anderson though.
