Backstory, so I stumbled on a junkyard pulled RSX type s K20 w/trans back in late 2017 for a steal of $300, so with extra spending money I had ordered performance parts to go with it.

I had an engine with nothing to swap it into. - I had gotten rid of all other past projects at this point and only had a CBR250R swapped Honda Grom as a toy.

So I set out to find a car.

I'd first bought a 1st gen insight with the intention to have feather light drag car, but after I'd already bought it with a little remorse to wanting a FWD again, I'd found another deal on a $3000 zz30.

Now that I had that correct chassis, I put it all together with a gt35 turbo, 2200cc injectors, E85 fuel system, and other matching performance parts short of internals I had it tuned at Humble Performance in Tulsa OK, making 544wHP on 24psi.

I've since swapped the turbo manifold for a more efficient one and have the boost setting at 28-29psi, with some mild compensation to the fuel table to keep the afr safe, so I'd imagine at that level it's closer to 600wHP.


I've had one chance to take it to the track for a single run. I was on street tires so the launch was very soft and even still it had a fair amount of wheel spin.

1/4mile: 11.3 @ 135mph

After that event I ordered a set of drag radials and drag wheels.

Now that I've realized my full intentions with the car the progress so far has been to;

-Remove as much weight as possible to make up for the installation of an 8.50 NHRA cage, & accompanying safety equipment.

-Move my Air to Water Ice box and fuel cell as far forward as possible to act as ballast for some wheelie control.

- Build out a CSS k20 block and drag cartel valvetrain

Don't forget to budget for a decent gear set. That k20 gear set won't last many passes with 600hp and drag slicks in the rear of a mid mounted car
A dog box transmission is part of the plan, it will just have to wait until this one inevitably breaks.
It's the most expensive single item in the process.
It's going to stay H - pattern, in case I want to sign it into events I don't get placed in the sequential category.

At which one do you look for? I am interested as on a side project I am also looking for one. The cheapest I've found is the Infinitude 6 gear set, but the gear set is more a circuit gear ratio then a drag gear ratio. Here in Europe there is also SQS Racing, which is a bit above pricing of the later. But they got good feedback from the racing scene. The MFactory set or even the Quaife dog box set is above my budget. So I am curious if you have some other options at your place.

There's only four dog box gear sets to choose from that I'm aware of, with a drag ratio set up.

Graf 1-4: $5899
(2.91 / 2.00 / 1.40 / 1.05)

PPG 1-4: $6038
(2.615 / 1.611 / 1.150 / 0.909)

Gear-X 1-4: $4895
(2.455 / 1.667 / 1.222 / 0.950)

Current ratio is a factory '03 RSX type s:
3.267 / 2.130 /1.517 / 1.147 / (5th gear) 0.921 / (6th gear) 0.738
FD Ratio 4.389

**these prices are on Nov. 21st, 2021 so they might be priced on a black Friday sale... IDK

great build, thank you for sharing. Do MR2's have a traction bar systems available similar to the ones the sell for the FWD market. A few buddies of mine have had MR2's with high levels of boost on Toyota engines and they would spin around and do 360 like nothing at 100mph from traction problems, hopping etc. With a Honda K, the engine will have more snap to it.
