Cheap lil N/A setup...

[Sonnick]

It'd be nice if someone hurried up and installed thier cam and hit a dyno. Then we'd have somewhat of a base for others to improve on and look at. Guestimate...10whp? Port and Polish jobs vary...if you're going N/A you dont want to hog them out too much cuz then you lose velocity. A good cleaning up of the casting, blending the ports, matching the ports on IN and EX side would be good enough.

Only 10whp from the PnP plus cam

The cam alone should yield 15+ whp if tuned right. Plus, coupling everything together, like the bolt ons together provide 10-15whp, while alone they don't do much at all. The high compression along with the aggressive cam will make great power too when everything is combined. I say the F23 is capable, N/A for about 250whp. The F22 did it..

I was referring to the cam alone, and it was a guestimate on an all otherwise stock setup.

FYI - you dont need to bore the block. The F23 and K20 have the same bore (86mm) all it'd need is a good cleaning hone job.

So then your saying the only thing that I need to have work done to is the head?? If thats the case it would save me A LOT of time and money.

Oh, ok

Jmillz the H22 tranny has very short gears..unless you plan on revving over 7, I'd say the H23 would be better suited for our motor because of our inability to rev that high. Unless, like you said, forged pistons and rods, etc, then you should be ok to rev that high, along with better valvetrain of course. But unless you are revving over 7, I'd say H23 would better suit your goals.

Thanks for the input..............

seems like a good little build for our engines.

greg, you should try it out man

 

[CrosCntryAccord]

and the plans begin formulating in my head

 

[Roadrage]

Hey, another nub question, can this be run on a stock block on a stock tune safely?

Yeah what he said.....can it? or I we have to look for another block?

The pistons are not in the head and we're talking about pistons

To change to the K20 pistons, which will give you higher compression you will have to open up the bottom end. The point BCK was making is that the labor will be less extensive/costly than if you were to go to a larger bore piston and have to bore out the cylinders.

I'd love to, but I'd probably end up doing it ghetto style.

AKA - pull the head and oil pan, pull the rods and pistons out, wipe off the rod journals and cylinder walls, install everything, shove the head back on. Not exactly the best way of doing things.


This setup is gonna raise your compression a good bit, I'd say minimal VAFC or SAFC just so you can adjust the fuel accordingly. The better choice would probably a stand alone or maybe a piggy back with better options like E-manage.
