opinions on bisi build

[91cb7allday]

i have an f22a4, and im looking to make some power out of it.
i love bisimoto so i went and compiled some parts id like to save up for

stage 3 cam- 750
valves & springs- 440
intake mani- 550
cam gear- 140
12.0:1 pistons- 450

didnt see any headers, and my piping back from headers is pretty thick, so i found these megan headers for 160... ive heard decent reviews.

now the total is about 2500. with some new gaskets lol everything else should be able to hold up, since i drive like a grandpa, but how much power do you think id be making? im hoping for around 190, but ive never built up a motor, only worked on them.
will my money be well spent? cause damn, for 2500 i could buy ten of these motors

[erk]

Good power doesn't seem to made with these motors (not to say it cant be done) without the help of forced induction.

There are many good resources on this board all you have to do is search.

ive heard some nice numbers off my research.. but that would cost like double what i would like to spend. i would like to remain naturally aspirated but im not trying to spend an arm and a leg just to get to 200hp. it would be more convenient for an H swap but the F series are a bit more torquey. . if thats a word.

So you're basing your goals off of the product availability of one vendor's website? It sounds to me like you don't really have goals you've thought about all that much. Do you have any idea how a camshaft like that will behave on the road? I don't care if you drive like an old man or not. Have you allocated any funds for tuning? What about all of the other stuff like seals, gaskets, fluids and unforseen parts expenses involved in an undertaking like this?

When you buy valves are you simply going to toss them in and go? The answer is no as you'll need machine work to match the seats to the valves. If you're getting oversized valves then there's even more seat work needed. With stock-sized valves I'd still recommend a multi-angle valve job to make it worthwhile. That's quite a bit of machining costs you likely aren't counting on.

What intake manifold are you referring to? If your budget allows for that much for an intake manifold then I'll take my H23A1 manifold off the shelf for you and have it going your way now!

And these 12:1 CR pistons you're wanting to install make the lack of mention of a tune all that more concerning. Good luck. Also, what bore? 85mm or 86mm? If 85 then I hope your cylinder walls are perfect and if 86 then I hope you're prepared to pay even more machine shop costs for boring the cylinders.

Since the head is coming off the block you're basically doing an entire rebuild. Every seal and gasket will need to be replaced. Also, it's the perfect time to do your timing belt, tensioners and water pump. There's another $150 at least. Just for that.

Pull up a chair and spend a while reading before you post your plans for a little while. They are a little short-sighted.

Also, you couldn't find a header on Bisimoto's website? Odd.

You haven't done much research. Theres plenty of NA builds here with F series motors.

Anyways, I'm kinda in the same boat as you op. I'm compiling parts as well for a build. Idk about the stage 3 cam is too much I think. Even the stage 1 requires tuning. Which Is necessary for this list you have. But if you drive like a gramps whats the point??

Edit: damn jarett you posted all that before I did my little paragraph. I am on my phone though. Lol

LMAO what? seems you need to stop and do alot of research yourself. The F series has loads of potential N/A.

heres a members stock block/head F22 with a Bisi cam/valve springs /Intake/bisi header/exhaust currently making 174whp/161tq.
Heres his MRT...

didnt see any headers,

NO FUCKING WAY.

If you simply google Bisi, im sure the first 12 pages of Google are reviews based soley on his headers ROFL.


You did 0 research, because if you did, you would have seen PLENTY on his headers.

Sneaky sneaky, sir.

i have all the tools i need. i have access to machine shops my buddy is in. i have access to anything i could possibly need. you really think i can do this all in my garage? i dont even have a lift in there, so ill be taking that to a shop i have access to. this is all through school and my teachers like me so i can do it all for free. the machine shop teachers know me too. im not stupid, im getting a head from my buddy to work on while its NOT in my car. cause i wanna be able to.. umm. drive it?

i was on bisi's site for like 5 mins. honestly im fine with the megans. and you guys are dicks im deleting this thread

We're not trying to be dicks, but we just get upset when people don't do their research and want quick answers.

No hard feelings.

It's just funny you found no headers when if you look, it's a big deal.

[Sordz]

I'd say double your budget, still need to consider these-

rods
bearings
head studs
fuel pump/injectors
chipped computer and software
dyno time and tune
clutch
swapping to H transmission(your choice)
water pump, oil pump, timing belt etc etc

If you have a place to work on the car and people to help you it would be a fun project and you will learn a lot.

[Quashish]

No ones being a dick. were trying to help you realize that theres more work involved than slapping parts in and going. Which is what it sounds like you were intending to do from your first post. Get thicker skin like your piping.

Sorry, I meant to say GOOD power CHEAPLY, I know there are n/a builds making upwards of ~190whp but at what cost? HP per dollar FI is where its at (referring to F series atleast)

Once again I said GOOD power. I (personally) couldn't justify spending that kind of money on Bisi's parts for all for 175whp. Even then you are just getting into the power capabilities of an H22, but this thread isnt about the H series, so Ill just stop right there.
