Six Sigma Racing/Quartersports 2.3L H2B CRX budget build MONSTER!
We haven't posted anything up in a long time, but I guess it's a good thing because we've been so busy working on our new product line, rebuilding the racecar and renovating the shop. Even though we don't have a racecar to play with, due to Danny's little accident, we have been helping out one of the guys at the shop on this little budget project.
Here is the break down of the build:
Picked up a core H22a4 block about 6 months ago from a dismantling company here in Stockton for $100... "yeah what a deal huh" Tore it down to fine out it only had a spun rod bearing, so out went the 90MM crank and in went the 97MM F23 crank.

Thanks to Seth Townsend of Quartersport for supplying us with a set of F23 Rods that we attached to our H22A4 pistons. Knowing that our f23 crank/rod combination with H22A4 piston would put the piston out the hole roughly .038, the pistons were sent to our machine shop to have the pistons decked .030" and valves reliefs cut .040 to give us proper clearance for a set of Blox Stage 2 cams. Before the block was reassembled, all balance shafts were removed and plugged. Since we are cheap, a fresh coat of copper spray was used on the original head gasket seal the factory non ported head to the block.


Anyone that drives a late model H22a4 knows that these blocks are usually matted up to a type SH transmission Well this was a problem for us because on the back of the block we were unable to fabricate a B-series half shaft adapter plate for our H2B kit. Our only option was to weld aluminum bar stock onto the back of the block and tap and thread our own half-shaft mounts. You can see on the picture below that its a B-series half shaft mounted directly on the back of the H22A4 block

Since fabrication is our forte and spending money is not....we made our own engine mounts.. We used a 94-00 driver side integra mount and a 96-00 civic mount for the passenger side and a factory 91 CRX rear mount along with a custom rear engine bracket. We had to taake into consideration that the engine would be removed and replaced several times during the build so we used mount combinations that would make it as east as possible for us.

When the motor was finally set inside the CRX, we had to address the issue of using our Hydraulic B16A tranny. We tried making our cable to hydraulic conversion kit similar to the Hasport one, but we were not satisfied with the results. Our next idea was to get rid of the whole cable completely and run a hydraulic master cylinder. It took us a minute to figure out how we would mount the cylinder, but after seeing a similar setup (thanks Joe), we started ripping out the dash..... We mounted the master clyinder ina reverse position inside the dash hooked it up to the clutch pedal.. don't ask how we figured it out, but it worked and that's all that matters..



With the clutch issue addressed, the last thing we had to do was to make a custom H2B header.. Since our product line already consists of a H22 Prelude chassis header, it wasn't a big issue for us to make a H2B header by changing the pitch of the lower section by about 15 degrees. The picture below shows H22 Prelude header on the right and the H2B header on the left.


here is what it looks like all done

Gangsta *** build can I get a Header like that even the used one you have there for a cheap price. Do you do military discount hahaha.
That's pretty good what amazes me is that peak power is well past 8000 and you're taking the stock F23 rods to 9000? those spindly little rod bolts and those heavy slugs are holding together? Man that's good news for me.
Thanks for sharing! I hope business is going well for you guys.

WOW!! thats what im saying. This is about the kinda power I am hoping to make with my engine. You've given me lots of hope here Danny.
Now get that beast out to a strip ASAP

Impressive, thanks for posting it up. How was it tuned, and did you get an A/F measurement? Stock OEM F23 rods were used, right? Any idea what your static compression ended up at with the modified pistons? It looks like the various mounts were well made, which is nice to see on a "budget" build!
Danny hit me up, we were supposed hook up last weekend...I have the sunroof cap for this car...Let me know.
very nice results 
I wanted to do this setup, but like Pirate, I'm very skeptical about spinning those skinny, long rods that high, but hey, looks like its holding up well so far, which is great news
Are the blox cams skunk regular series replicas or pro series?

F20C pistons with their 1.171 CH are a much better option than H22 pistons. They work perfectly with the FRM liners, they share the same pin diameter and bore size as H22 pistons, they are forged and they can be found fairly cheap on S2000 web forums.
No machining required and they sit a few thou in the hole as apposed to sticking way out.
Long live the H, nice job Danny/Derek
