I'm researching the best options to boost a 5th gen Accord, and it looks like the non-vtec is preferred, due to the better flowing heads. Is that to say that it's going to make substantial power over the VTEC head? I like the EX platform since it has some nicer features such as sunroof and factory 4 wheel discs, but as far as the engine non-VTEC sounds like the way to go. Would it be worth getting rid of the VTEC head and going non-VTEC head like the F22A or is that going to cause more headaches trying to do away with the VTEC and ecu/wiring? Would I be better off just finding a non-VTEC model and upgrading to EX components throughout the car?

As far as the F22a, the reason I would consider it is because it has the better flow (is the A6 or A4 better?) and because it would make sourcing a turbo mani a lot easier since you can run a DSM manifold (either stock or a nice tubular should be easy to find). Is there a writeup on how to swap an F22a head onto an F22b block? I tried researching but couldn't seem to come across anything, maybe I'm just using the wrong search parameters...

 

Some will say that F22A6 head flows best which is true but You can always make alot of power from the F22B1. Just PNP the B1 head and you'll def. the big gain.

man i can get a f22 for 400 right now should i get it and turbo it or not

 

Do a leak down test to see if motor's still good in compression. If it is, Turbo it. You won't regret.

 

Get the car that already has any options that you want. IMO, any difference in the heads is minor, unless you're on some quest to have the highest-horsepower, stock-block Accord. Which brings me to the question, what are your goals with this car?

F22's can be had for cheaper. Whether or not you should get it depends on what you drive, and what your goals are.

 

I'd love to have a decent handling, good gas mileage turbo DD. I don't want to get crazy like 600hp, maybe 350ish on pump gas if that's possible without getting too radical, perhaps a rod/piston setup. Main reason I was looking at the F22A head is because DSM manifolds are plentiful, and thus much cheaper. I've been trying to find out what kind of power the block can handle without needing sleeves or block guard, but not getting much response.

 

h22 head, f23 block, k20 pistons = g23 someone try it

 

There's a lot of varying opinions about how much a stock block can withstand reliably. Of course, it all boils down to tuning. Can 350 whp be done on a stock block? Sure... but the pistons (ringlands specifically) may not last that long. The sleeves can withstand a lot more than that, again, assuming the tune is good.

I'd say if you're aiming for 350 whp, and you're on a budget, you could probably do without sleeves. Pistons, rods, and a safe tune, and you should be good to go. Just remember that power is addictive, and it's just too damn easy to turn up the boost...

 

True. I may just go ahead and spring for a block guard or do like ashb82 and create my own of sorts from that liquid aluminum like he used. F22's are pretty cheap, so I can experiment a little

 

There was one thing I don't remember ashb82 ever mentioning about the DIY liquid aluminum (Devcon) block guard. For it to cure to it's strongest and have it's full aluminum like qualities. It has to be bake cured @ 200°C for 2 hours. Do you have an oven that you can bake a block in? Maybe he didn't use this curing method???? It will probably still hold. All I know is that it states right on the instructions. For strongest results let set for 2 hrs. Then cure @ 200°C for another 2 hrs.

I did port shaping work on my head and intake with Devcon. I used the bake cure process because it said to do it on the instructions. Also from what I have been told by a local race engine builder. There is a big difference in the end result. It acts more like aluminum when cured this way. It will withstand the heating and cooling cycles much better. Just a heads up.

 

Thanks for that, I'll have to keep that in mind for future reference. Would a powdercoating oven be hot enough?

 

Yes, most powder coating processes require ovens that will range between 160°C - 210°C.

 

how much boost will this motor being bone stock
