well i have come up with a game plan for my new setup.
F22A head cnc ported
F23A block bored 1mm over
CP piston 87mm -9cc dome for k20/k24
Carrillo pro A-beam rods for k20
Rosko racing modified K24 crank for use in F23 block.
bisi v3 header or custom long tube 4-1 header
3" exhaust
ITB's (probably kinslers)
only a 1.4 R/S ratio but hell i dont plan on anything past 7400rpm anyways.
im projecting right at 198whp if i use all the same bolt-ons, ie before the new header, ITB's and larger exhaust. this may sound stupid or be wrong but i knew my current setup would make 187whp. turns out my bisi level 2 is the same as my web level 1. they're both stamped from web 148E+3. so i figured in my old static compression (8.8:1) with my old whp (174) and put in my new compression ratio here http://www.wallaceracing.com/hp-cr-chg.php which gave me 178.79. then i divided that by the old displacement in cc then multiply it by the new displacement in cc. example: ((178.79whp/2156cc)x2254cc)=186.9whp. i did the same math for the new setup i want to build and came up with the 198whp before the intake and exhaust upgrades.
That is what I like about you. You have real world numbers and the experience to back it up. I hate it when people say that if they had a "built" motor that it would make like 300whp and would run a 10 second quarter mile.
I've learned quite a bit from your build and your knowledge, gotten a few headaches too (hate math) but it's refreshing to see that you're still focused and continue to go deeper into the build. Good luck with new plan!
I use that Wallace racing site all the time to validate/compare with my calculations. It is a great utility.
That new build list looks pretty solid! If you are going this in depth. I would try and find someone to build you a dyno run custom header. It would be well worth the money spent.
ive been thinking more about a custom header in the past few months. i have all the formulas to build what i want i just need the materials. the cost of the materials is the biggest issue next to welding. i cant weld at all so im stuck paying my buddy Ben to do it. he quoted me $1500 completed, bolted on and tuned. i think with the custom header, properly sized kinsler itb's and a 3" exhaust i would put it at around 215-220whp and 180-190wtq. it'd basically act like a v6 in a I4 package, lol.
I cannot imagine what this thing will do at the track with 200+ whp / 180+ tq.
Also, accorn the guy who bought your hytech rep header. Has he ever reported back about the gains from that thing? Just curious, somewhat sad that it never got to be on YOUR car :/
You never know, I might make another one now that the car is running again and I have a backup. I might try to make a rmf replica aswell and do a comparison between the bisi, rmf rep and hytech rep. I also might be picking up a del sol for a F2D or F2B swap.
