Hi guys, can you please critique my build? I have tried to do my due diligence, but I'm still a full blow noob and know just enough to spend a lot of money on the wrong parts. I'd love your help or suggestions on my build.

I have read that a lot of people are getting 250whp FWD from Franks on 93 or higher octane. I'm trying to do the same but RWD (with an S2000 Transmission) and 91 octane so my results will be lower than your typical FWD frank build.

I'm starting off with two long blocks (both engines are sitting in my garage right now)
2008 TSX K24a2
2006 RSX K20Z1

My build is as follows

Used Parts
2008 K24a2 Bottom End
2008 K24a2 Cams

K20Z1 Head
K20Z1 Oil pump
K20Z1 Oil Cooler
50 degress VTC gear

TWM ITB 52mm (Bought on a whim)
440cc injectors (Came with TWM)

New Parts (Not yet bought)
AEM Infinity ECU (this is on purpose for the data logging features, Flex fuel E85 features, and communication with the CD-7)
Morso Pan
ATI Super Damper
Ballade Sports Flywheel and Engine Adapter
New Clutch
Thermal Spacer
Long Tube Header, 4-2-1 Tri-Y design 48mm primaries, then 54mm secondaries and finally 3" exit
AC, Power Steering delete


k24a2 Head Gasket
Valve Cover Gasket
Head Studs? (are new ones needed?)
K24a2 Timing Chain and Oil Chain
K-series Lower Timing Chain Guide
OEM timing chain tensioner


Thoughts, suggestions? It's for a locost build, see image below.
Thanks!

Where I got most of my build ideas is from, Evans Tuning videos.

250whp K24 is pretty easy. I don't think in RWD form you can get there on stock cams though. I think you will have a hard time getting there on stock head ports. Strongly suggest you read my build thread. https://www.s2ki.com/forums/automoti...years-1175851/
You need to remember the K20 and K24 heads don't flow that great compared to a F head. The F heads flow like 330cfm. The K24 (rbb head) that I flow tested only flowed 280cfm. A K20 head (there are several) at best will flow like high 290's cfm. Thats at the peak of things like 20-30hp less then what a stock F series head will flow. A Civic Type R head flows like 310 and I think thats the one to go with if you don't want to spend money on head porting. I had my RBB (K24 head) ported by hand by someone locally and it easily ported out to 320cfm. That said the K20 head currently on the car is ported out to 360cfm. Non-ported K20/24 combo's make over 250whp all the time in FWD setups. But in RWD you just have to many losses to get you there In my opinion.
