N/A K24 Atom '300' in Norcal

**Payne** · February 18, 2011, 07:10 PM

Jason here. I'm building a K24A2 powered Atom3 in Norcal (buying a roller from TMI and building the driveline myself to be legal in CA).

Hoping to make about 260rwhp and 180rwtq on the first motor (stock longblock + cams + all bolt ons), and then step up to a 300-330 rwhp built longblock (high compression, ported head, etc) next season, or possibly go turbo.

I visited the TMI factory this week, chassis is coming along well. Should be done next month, and I'm hoping to have her sorted this summer. Eventual goal is to run faster than 1:33 at Laguna Seca.

Basics of the car:

2011 Atom 3[/*:m:m2fe6urv]
matte chassis[/*:m:m2fe6urv]
matte panels[/*:m:m2fe6urv]
Wilwoods[/*:m:m2fe6urv]
most of the other track goodies - fire suppression, 6 point harness, roll bar, etc[/*:m:m2fe6urv]
15/17 combo with at least RA1s, likely A6s.[/*:m:m2fe6urv]
All custom LED light bars - no Madonnas, no tractor lights.[/*:m:m2fe6urv]

Planned driveline:

K24A2 engine - 2.4L K series out of a 2005 Acura TSX[/*:m:m2fe6urv]
Medium cams[/*:m:m2fe6urv]
Stronger timing chain tensioner[/*:m:m2fe6urv]
Dual Valvesprings[/*:m:m2fe6urv]
Ported K20A2 oil pump[/*:m:m2fe6urv]
oil pan baffle[/*:m:m2fe6urv]
ported RRC intake[/*:m:m2fe6urv]
74MM TB - cable operated[/*:m:m2fe6urv]
K-PRO ECU[/*:m:m2fe6urv]
shift light[/*:m:m2fe6urv]
oil pressure safety light[/*:m:m2fe6urv]
Atom 300 electric water pump (for AutoX staging lane cooling)[/*:m:m2fe6urv]
K20A lightweight flywheel[/*:m:m2fe6urv]
OEM style clutch[/*:m:m2fe6urv]
K20Z3 tranny[/*:m:m2fe6urv]
K20A2 Final Drive and 6th gear (4.38 FD for the wider powerband of the K24 and shorter 6th to pull it on the track)[/*:m:m2fe6urv]

As an introduction, I've owned a few other performance rigs in my day:
1993 RX7 with a 400rwhp LS1 that was a CARB legal swap
2002 z06 with a 383, nitrous, coilovers, etc
1998 Viper with a supercharger, HREs, Wilwoods, etc

Looks to be some great experience here and a lot of racers/tinkerers, and not too many waxers. I'm hoping I fit in well.

Cheers,
Jason

Welcome, The black matte looks good.

So do they pull the engine back out before shipping it to you?

I think the green tape in this picture says "just visiting"...

Welcome Payne! Your car looks great. I do think I see a quarter inch of clearance between that valve cover and body cover.

Welcome Jason, I do like the matte black

Welcome! Can't wait to see her all finished!

The motor is TMIs mule motor, they'll finish the car, run it with the mule for a few miles to make sure everything checks out, then pull the motor and ship the roller to me with no driveline.

Here's my motor : I've not cracked it open yet, but have a huge pile of parts ready for the build:
