I have a NEW Datsun Competition 2-stage oil pump, with a New Tholen Designs TDC oil pan (that has not been drilled and tapped for the oil scavenge yet, and a valve cover that was welded shut to seal the engine. I would like $1500 USD for the set plus shipping. If you think the price is too high, make me an offer. Who knows, I may accept it.

The pans were designed for the A12 crankshaft, but with a little massaging, they can be used on A13/A14 engines.

I buy, sell and trade Datsun A-series parts in connection with my racing (and for fun). [I've got 10,000 Datsun A-series engine parts in my garage. Need something?] I bought these items from racers who started projects in 1984, and never finished the engines. My current setup does not require these parts, so they are for sale.

Thank you, Peter

Here are the 45 DHLA bodies bored to 48; and the original 48s with a repair plate to fix the cracked mounting flange. They do not look pretty, but they worked.

My suggestion would be to transfer everything over to the undamaged bodies.

Hello, I have been running Dellorto 45 and 48 DHLA and Weber 45 DCOE on my Datsun A13 powered race car. I don't think I need to have 4 complete sets of carbs for one race car, so some of these are offered for sale.

Set #1: New/rebuilt pair of 48 Dellorto DHLA with only dyno time and 1 test day at the track. These were built up by taking a set of good 40 DHLA bodies and boring the bodies to accept all of the 48 chokes and throttle plates. These have large, 40mm chokes in them and they are jetted for my 1300cc Datsun at high rpm (using 7500-10,000). $1000 USD plus shipping. I have invested probably 2-3 times that much. These are compete and ready to bolt onto a manifold and race. 2-DHLAs.

Set #2: A pair of 48 DHLA carb bodies and all of the parts to build them. $500 USD plus shipping. This is a package that includes (2) 48 DHLA that were running; (2) 45 DHLA bodies that have been bored to accept all of the 48 components; and all of the parts to assemble (2) complete carbs with jets/chokes etc. You will get many extra DHLA parts. The 48 DHLA pair has been repaired, so you can either use that pair OR put everything into the bored out 45 DHLA.

I also have Set #3: A complete and running pair of 45 DHLA with 40mm chokes. Used but in very good condition. $1000 USD plus shipping. [I also have other smaller 45 and 48mm chokes, so these can be made to work with lower rpm engines.]

OR PACKAGE: IF someone bought all of my DHLA carb sets listed above for $2500, I would include large storage bins with jets of all sized and DHLA tuning parts. I spent tens of thousands of dollars over the last few years doing dyno tests to find the best for my engine. My air/fuel ratio curves are very flat for carburated dyno pulls.

Thank you, Peter

My 1300cc engines (using the 45 or 48 Dellortos and/or the 45 Webers) are 9800 rpm engines, 15:1 compression, 0.650" lift at the valve using either 1.60 or 1.65 roller rockers, camshafts built on blanks (when I can find them) with banana shaped opening ramps, Carillo or other H-beam rods, billet crankshafts. We use 10mm or 3/8" rocker tower studs and make our own steel rocker towers. Each tower is built for that engine, so to maximize the rocker ratio. Titanium valves are 7mm stems. Valve train is "little" beehive valve springs and Titanium retainers about 25mm diameter.

Four years ago I did extensive dyno testing and built up several sets of twin Dellortos. My baseline was my longtime set of 45 Weber DCOEs. [I run high RPMs, so I use bigger chokes in all of these.]

When I was all done, the 45 Webers with 40 chokes; 45 Dellortos with 40 or 41 chokes and the 48 Dellortos with 40 or 41 chokes all gave me about the same results. [I learn the hard way. I should have spent my time on something else.]

For Sale:
1) I have a pair of new (rebuilt) 48 Dellorto DHLA. Carbs were bought from Italy as 45 DHLA that the Italian company bores out to fit 48 parts. I have several thousands of US dollars in the pair. (about $2500 USD for 2 DHLAs). I will sell them complete with the jetting just as they came off the engine in dyno tuning. They were only run on the track in test days after dyno testing. $1000 USD plus shipping.

2) I have a different pair of very good 45 DHLA Dellortos. These I dyno tested and raced for several seasons. Complete as they came off of the engine. $1000 plus shipping.

Now, for the bargain hunter, ...... I have (2) original 48 DHLA carb bodies that were used and running, great carburetors until ..... Someone tightened them too tight on the manifold and CRACKED the mounting flanges. At that time they were the only carburetors for that car/engine, so some 3mm thick aluminum plates were fashioned as braces and then drilled, tapped and attached to these "cracked" 48 DHLA carbs, fixing them. We raced with them and they worked good. But later they were disassembled and now sit on the shelf. PLUS I will include (2) more UN CRACKED 45 DHLA bodies as donors if you want a prettier finished carb setup. So: (2) repaired 48 DHLA bodies; plus (2) 45 DHLA bodies; and all of the DHLA parts, jets, throttle shafts, plates, etc to put (2) carburetors back together. $500 plus shipping.

I have a Datsun Competition limited slip for an H145 rear end. [I use the H190 rear end in my Datsun 1200, so this piece should go to a new owner.] Very little use.

$1000 USD plus shipping from USA.

I will try to get pictures up.
Thank you, Peter

For sale: I have a set of (5) A14 forged dome pistons, 77mm is +1mm overbore. The dome is 0.300" high. The dome is not undercut, so they can be machined flat top. I will include this for no charge if you tell me you want flat top.

(3) are good used and (2) are new, never used but cut for valve reliefs and modified for 2-ring design.

These are 2-ring design pistons that started life as 3 ring Wiseco race pistons. [Ignore the top ring, except that the top ring is welded shut for 20mm near the intake valve relief.] See picture. This modification was used competitively. [I did not think it up.]

$300 USD plus shipping.

Note: I have two sets of 77mm Wiseco race pistons for sale, a total of (9) pistons. If someone wants both sets of pistons I would ship for free (a good bargain for international buyers) and I would include several sets of piston rings and pin clips.

I am now racing 75mm Wiseco pistons in my A13.

I have a set of A14 forged dome pistons I took out of a running A14 race engine. $300 USD for the set of 4 good pistons. These are Wiseco forged 2-ring design. The dome is not full height as new (0.300"), closer to 0.200" above the deck. These pistons have very large valve reliefs. They can be made made into flat top pistons too. The underside of the dome is not relieved.

These can be used in an A12 with con rods with the 19mm small end.

Note: I have two sets of 77mm Wiseco race pistons for sale here, a total of (9) pistons. If someone wants both sets of pistons I would ship for free (a good bargain for international buyers) and I would include several sets of piston rings and pin clips.

I am now racing 75mm Wiseco pistons in my A13.

You will have no problem using the early GX head on the later A15 block. The oil will come up the center spark plug side head bolt over to the rocker tower.

Use the A15 head bolts with the "13" on them and remember that the middle spark plug side bolt is longer than all of the others. Use the FelPro 21199PT-1 head gasket.
