F22A SOHC non-VTEC boost build

[ivarcj]

Ok all... after blowing my first stock f22 i decided to up the stakes a lil bit so this is where i'm at thus far with my new build. I'm building an f22a4 i picked up after my original f22a6 blew. Well not totally. The cylinders held up great and showed absolutely no signs of cracks so why didn't i re-elect to just rebuild what i had you ask? I'm glad you asked! i didn't rebuild it because i previously had the block bored over .030 and id been tossing around in my mind .."just how much boost can a stock block take"? So with that in mind and not enough money to have it sleeved, being bored .030 was taking a fairly big chunk of iron from my stock cylinders and seeing how under 19 lbs and some cracked ringlands later the cylinders still looked great. i almost elected to go with an 86 mm piston and those are easy to come by as there are several companies out there that produce em but it still lingers in my mind that its thinning the cylinder walls quite a bit and i'm wanting to build a reliable DD. So i elected to have a custom set of 85 mm 9:1's built for me in hopes to make good HP and keep reliability. Thus far the block guard has been fit and the pistons matched to the cylinders and the block has been honed to spec. im waiting on my ring set from wiseco to continue as my "2nd" rings were to loose from what was spec'd. So here is my current build sheet


Engine:
f22a4
9:1 forged pistons
forged H beam rods
KMS block guard
Stock crank
ARP head studs
Toga high volume oil pump
ACL bearings
Hondata s300
precision 880cc injectors
Hondata 4 bar map sensor
hondata electric boost controller
AEM wideband 02 sensor and gauge
OBX intake/H series throttle body
omni 70 mm throttle body
ACT 6 puck clutch
ACT extreme pressure plate
Walbro 255 fuel pump
ebay turbo log manifold
precision turbo 6152E
turbonetics delta II wastegate
Stock Sohc head with upgrades:
5 angle valve job
mild port and polish
supertech valves(1mm over-sized intake,2mm over-sized exhaust)
bisimoto titanium springs
bisimoto 1.2 cam
bisimoto 5 layer head gasket
bisimoto intake gasket

that about covers the engine. I'll edit it if i forgot anything.

I dont always make stupid post, but when I do its to let some one know that they are a Honda Enthusiast and have SPELLED VTECH instead of TYPED the acronym VTEC!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!9k!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!9k!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!9K!

baaa haa hahaaaa tnx man im so used to doing it screwing with my friends.. i also usually say soch as my name in another forum is sochbandit.. get it SOCK bandit. Vtec? whats Vtech? LOL

ok well so far nothing but issues...honed my block and began clearancing and matching my pistons to cylinders... checked ring gap clearance and tops came out to spec. 2nd's were way to loose so i called weisco up and they sent me out another complete set.. Back to building... opps THEY SENT ME THE SAME EXACT WRONG SET. so i called em up again and the send me a tighter set and i filed them myself to specs which was .016 tops ..... and .018 2nd's. on to the build... clearanced my main bearings and they came in ok but rods were to loose so i took my crank and had it micropolished and rechecked the rod bearing clearance.. still to tight.. so i had em take it down a couple 10 thousandths. and they seemed to come in good.. so we assembled the bottom end.. as i went to go get some oil oil pan gasket and a filter to finish up the bottom end... my buddy began to mount the oil pump.. to his dismay the engine was locked up.... upon further inspection and alot of measuring we came to the conclusion that the rod big bore opening was not properly machined to hold the bearings..... after some somewhat heated conversations through email with the manufacturer they are sending me a new set of rods"although they claim the ones i sent back were within tolerances"...PSSSTT HARDLY!!!!!! the bearings seemed to big when they were placed into the h beam rods though they seemed to fit flawlessly when put into my stock rods,,"GO FIGURE"... so as it stands im waiting on another set of rods and ordering another set of rod bearings..... hurry up and wait...

Just a question, why would you order rod bearings before you even have the rods in hand with measurements? Also what brand H beam rods are you buying, wouldn't happen to be Eagle would it....... They have been said to have some differing BE diameters from time to time.

Nothing a little machining or different bearings wouldn't fix. One size fits all bearings aren't always the best bet if you want to run specific clearances. IMO OEM colour match bearings would be a more reliable way to go.

Oh BTW, nice build list..... Good luck!



P.S. don't forget to hone/bore the cylinders after setting the block guard in place. Are you having it welded in place or press fit?

Just a question how much money did you put towards this build?

i just pissed my self.LMFAO!


anyway.i have to agree with gost here,.how did you acquire your clearances for the bottom end?i believe you would have to plastic gage the rods and mains.honda i think recommends .15-.18 clearance.

A micrometer and dial bore gauge would be even better.

as of now i haven't ordered any bearings JUST YET.. IM WAITING TILL I HAVE THE RODS IN HAND LOL. funny you asked why yes they are eagles... they ranted and ranted that they were within clearance even after i sent them pics with the stock rod with the bearing in it VS their rod with the rod bearing in it. yea im running a lil looser clearances to be on the safe side since its a boost application... oh and yes sir i did hand sand the block guard till it fit in just perfect then tig /tacked it in a few places and this was done before i honed the block. thanks for the kind words. you have been a big inspiration to me in regards to what can be done with an f22 sir.

As of now with hondata s300 and all parts im up at a bit over 3k.

you would be correct sir.. i plasti gauged my mains and rods TWICE and then double checked with a mic and dial bore gauge and surprisingly enough the plast gauge "at least in this case" was very close and yes im running my clearances at .018-.019 to be on the safe side" i dont want to starve the bearings under boost" since im planning to run somewhere in the area of 15 to 20 lbs consistently as a DD.

Well to be honest with you I love the fact that you will have a boosted car no doubt about it. And I would love to see your project lift off the ground but once it's done your going to want more. I strongly recommend that later on that you down the line get a already boosted from the factory car.

To be honest with you for the past couple of years of wasting money the speed was great ,what a rush but the reliability and the feeling of beating the piss out of a car without it having to break down is much better than something a little experimental you know what I mean?

[ivarcj]

Idk how many"from the factory" boosted 350-400,HP cars there are out there...much less one that I can afford.why you feel like mine won't be reliable? I'm doing the right things?

[deevergote]

350-400whp from a boosted 4 cylinder is going to be a risk no matter what. No factory 4 cylinder makes that much power, and there's a reason for it1
An engine that was built to push 300hp at the crank is built from the factory, designed by engineers, to withstand that power for a long time. Building an old Honda engine, even the right way, will always be a risk. The parts aren't all "made for each other", and even with care and experience, you're still touching EVERY part of the engine. The more you touch, the more chance you have of making a mistake.
