1991 Accord LX Race Car

So for months a friend and I have been slaving over an '86 Mustang to enter in the upcoming Sears Pointless LeMons race at Sears Point.

LeMons is a race series for cars that cost under $500. And the cars have to have a theme. Our mustang was themed after the 1971 Porsche 917 pink pig (google it).

Two weekends ago we got it together and test drove it. It went badly. Really badly. After some wailing and moaning we decided to dump the stang and look for something else. Yep we decided I spent days scouring craigslist and considering multi-state road trips to buy a car that had already raced in LeMons. The advantage of a raced car is that it passed tech inspection so the cage and safety gear is good enough. We got super lucky and found a 1991 Accord for sale just 20 or 30 miles from us. It had been in LeMons for one race in 2013. It's even registered (street legal) through the end of the month! Of course I know nearly nothing about old Accords. My knowledge of 911s from 1965 to 1995 is encyclopedic, but hondas, not so much. I've joined up here where it looks like there is a bank of knowledge and helpful enthusiasts.

So it was advertised as having just one problem. They cross threaded the crown nut on the bottom of the right lower ball joint. After getting it on jack stands I took off the wheels and one of the rear lug nuts was waay overtightened. It sheared right off. I took the drum off and took apart the hub so I could hammer out the broken stud. $1.99 for a new stud and $5.99 for 4 new lug nuts and a bit of banging and it went back together. We found the cross threaded nut on the ball joint and got it off. We're going to use a tap and die to clean the threads and get a new nut on there.

On more thorough inspection we found a few other bits that need work. The exhaust manifold has a crack. The ball joints are pretty hammered. The 14" wheels have some all weather touring tires.

But the on the bright side it looks like someone did some front brake work. The calipers are single piston but they are big and the disks are vented. I don't know if that is stock but with some DOT4 and some race pads they should do the trick.

I'll post again shortly with some pictures. It looks like this forum doesn't host pics so I'll have to update my blog and link to them from there.

In the mean time, as soon as we get that nut on I want to take it to get pre-smogged. If it looks like it could pass I'll have to replace the manifold because the inspect for stuff like that and a leak in the exhaust will fail. Any way that presents an opportunity. I imagine there were several different manifolds available. I'd even guess that this engine might have been in some acura with a proper header on it. So since I have to replace the dang thing anyway, what should I be looking for? Any suggestions where to look?

F22Chris is very helpful F22Chris is very helpful
I'm going to assume you have an F22a1. For the header[if you're on a budget] go out and get yourself the header off an F22a6 found on EX models. They'll net you the same HP as the generic 4 to 1 headers you'll find on eBay or what have you. If you can weld, putting a 2.5" collector on there will net you even more gains. If you can't weld, and you might not find an a6 header that isn't already cracked from age/abuse, DCSports headers are CARB approved. If it doesn't have to be CARB legal, then Megan is the next best thing.

Here is the interior



Here is the cracked manifold :-(



Look at those pretty welds and that nice spreader plate.



I forgot to get some overall pictures. Later.

Bloody hell, next time I'll resize the photos first.

which motor?

F22Chris made me think of a good question.

How can I identify which motor I have? Based on looking up the car on automobile-catalogue.com it is probably the 2.2L F22a1.

I have seen it, it's fantastic, but I'm only on page 2 at this point.

It's stamped on the block under the water outlet & right of the tranny. Looking at the header, you have an a1 block. The 30HP for 500 bucks thread is .

This is accurate. But the header on the F22A4 is also good - perhaps even a bit better than the F22A6 header.

It's cool to see another Lemons car.

F22A4 exhaust manifold is better than the F22A6. I have several of each laying around. A4/A6 downpipes are interchangeable.

I'm really liking that seat and that roll cage! My car is begging for those.

I have seen the $500 hp thread. I wouldn't be considering the header if the existing one weren't cracked.

To me success in Lemons means getting to drive lots of laps and getting to do it again in another race. So the most important things are don't crash and don't break it.

This weekend I'm going to the Newark pick-n-pull their website shows that they have about 20 similar vintage accords and a handfull of preludes. I hope to get a header, a lower ball joint, and a rear sway bar. We're working on wheels as well. After that she's ready to roll.

Yes. My bad. The a4 header is a better design. It even looks like an aftermarket header.

Less than a week to the big race. God I hope it holds together. It's peppier than I expected, and though the suspension is very soft it should have prodigious grip due to the huge Dunlop Direzzas.

Sears Pointless 2016 Feb 13 and 14

We are just about ready. We've got the a4 header and a race muffler installed. The suspension we upgraded before thunderhill was magnificent. We are debating getting another day or two out of our tires or starting with new tires. I got rid of the AC compressor. We have new stoptech rotors and porterfield pads. The brake fluid is flushed with fresh Redline 600 fluid. The oil is changed. We replaced the windshield. I think we are ready to race.

Tomorrow we will do some cockpit de-scuzzification and maybe give it a bit more of a wash before we take it around the block.

We are entered in Feb 13 and 14 LeMons race at Sears Point (currently called Sonoma Raceway). It's going to be a blast. Tonight I will be updating the blog, after I have some new pics up there I will get them up here as well.

Build f or H series.

F22a6 worth rebuilding and boosting vs. swapping a H22a1 vtec?

Nothing will land a Honda in A class faster than VTEC. SOHC totally stock looking boooring early 90's motor is what we want. We put a VTEC in there and all of the sudden the judges will be sweating us for every detail of our car, when right now they pop the hood, say "this ain't winning anything" and give us B class with no penalty laps. We like B class.

Plus the thing people don't get, lots more horsepower means more wear on everything so parts break more often. CV joints, bearings, transmissions, motor mounts, motors, all of it. It means you need better brakes to slow you down at the end of straights, it means you chew up the tires faster, it means you burn more fuel. All of that costs money that could have been spent on tires, brake pads, and the next race's entry fees. The cb7/f22 is perfect for low budget lemons racing.

Also I hate to say it but VTEC motors don't do that well in Lemons. They're always blowing up or spinning bearings. I don't think it is necessarily that VTEC motors are unreliable but that the VTEC motors that can be bought for Lemons money aren't likely to be reliable.

Thunderhill Video

Video for all day Saturday is up on youtube.

Our first driver, Tedd. He's our ringer.
If you want to see how fast a CB7 can be driven:


Here are Derek's and Dennis' drives.




Finally my inauspicious Saturday drive. If you want to see what it looks like when a CV joint is failing skip to 27:30 and watch my hands shake.

upgraded brake problems

I got the knuckles off an acura CL3.0 with the assumption that they would hold the calipers in the right position for the 11.1" diameter disks. But once we got them on the car the calipers bottom out and cannot line up with the caliper bolt holes on the knuckles. :-(

I'm thinking I need to go back and get calipers from an acura cl3.0, but those will almost certainly be nissin calipers, and race pads are not readily available for the nissins :-(

Any suggestions?

I just ended up getting the calipers with the 25t brakcets off another acura cl 3.0. Now we have to order our pads to be made for us from Porterfield. Also got the sway bar off a Vigor and mounted it. That should be cool
