CARRILLO RODS
Racer set pricing includes the CARR BOLTS that never have to be changed for the life of the rod - rods equipped with the limited life WMC bolts are less expensive. We keep all the four cylinder Alfa units on the shelf and can order BMW, DATSUN, CHEVY, FORD, ETD. for the same price. Custom rods are available on request. Dealer and builder inquiries welcome. We also keep spare small end bushings and rod bolts on the shelf. We will sell single new rods if you happen to damage one

JE FORGED PISTONS
25% Lighter than Stock!

We can design and special order any piston you need!

We sell single pistons and pins if you damage one and need a spare. We stock spare ring sets, but unfortunately can not break sets to sell singles.

GENERAL NOTES. I have proven on the dyno that our designs on the JE billets make more power. We have been working with the people at JE on our pistons since 1978 and have yet to see a documented piston related failure. My friends in the NASCAR engine business turned me on to them and I have never strayed. Through our racing engine research and on track experience we have continuously modified the designs for better performance and ease of installation. We welcome customer input and have made a number of changes by popular request. We won three SCCA E-PRODUCTION National Championships using the same 81mm pistons you can now buy off our shelf. Our customers all over the world are winning races with our pistons. All of the professional Alfa engine builders use our JE design pistons. If you are not a pro, then you will enjoy following our three page set of instructions that come with each set. If you encounter problems or have questions, I am happy to help you over the phone or by email at any time: paul@paulspruell.com.

Reinforced Engine Mounts

	These act as torque arrestors (limits amount of engine rotation due to torque reaction) and prevent sagging of the rubber mount that holds the engine up. Never replace mounts again! Now in light weight billet aluminum!

Each mount includes reinforcement guards, but the reinforcement can be bought independently of the mount

RACE HEADERS
Equal length tri-Y design for low end torque. Mandrel bent, progressively staged, precision welded technology that makes these the best on the market at any price. Proper fit and clearance all around. Available in bare metal only.

( not available in chrome. I used the photo of customer headers
since it shows the detail better than black or grey)
New Performance Racing Headers for your Spider

***Black ceramic finished headers require heating to 750º Fahrenheit to be fully cured. Therefore, after installation, please allow your vehicle to idle for ½-1 hour to complete the curing process.***

Special instructions for exhaust/tailpipe connections..

For racing applications, one should install a 2 1/2" tail pipe somewhere between 42 and 46" in length for all displacements from 1300 to 2000. It takes dyno tuning to determine the absolute best length for each engine configuration. A good rule of thumb is that the shorter pipe yields more torque and the longer more top end. My advice is to run it straight back and hang it from the standard mounting bracket on the chassis. It is a good idea to have a 45 degree bend at the end to shoot the discharge at the pavement to mitigate the sound. We furnish a set of tabs that the customer can weld on to make this connection. We also furnish a sketch of how we mount the tailpipe on our race cars with photos from my ITB Spider (see below). Sorry, but we do not offer tail pipes for sale since they are dirt cheap and simple enough for a customer to do.

For street applications. Both the early and late model headers terminate forward of the standard system resonator with a single 2 3/8" collector tip pipe. To mate the headers to a stock exhaust system, a short section of pipe is required reducing the size from 2 3/8" header tip to 2" to make the union with the stock system. Any good muffler shop can accomplish this. Street systems should not use the tabs for attachment. The adapter pipe has to be welded to seal up the back pressure. Sorry, we do not sell custom exhaust systems.
