hi, as always i like to share my set ups with you and hear your opinions about them

b18c1 81x87.2
head pr3 polish, valves, spring and retainers all skunk2
manifold godspeed polish with 68mm thorttle body
nsx injectors 340 cc
toda spec C2 cams
honda oem gasket
block stock bore,
ctr pistons specting the compression to be between 12.0 and 12.5
arp rods and studs

planing to rev 9500 rpm
stock gsr rods

planing to tune with chrome

do u think i need to have something else? should i be able to reach 220 or +?

thanks guys i appreciated

 

So stock bottom end other than CTR pistons ? you won't see 9.5K very many times let alone make power into it. alot more is needed to hit 9.5k let alone make power into it

 

what do YOU think?

This is a technical discussion forum. Without specific questions there is only going to be random people recommending various changes to your build for various reasons. Some good reasons, some bad reasons. And some advice is going to come from people who are uneducated on these builds.

So with that said, what do you think? And what research have you done that would support the goals you have set? Not that revving to a certain RPM should be any goal.......

 

i havent found many builts with toda c cams, i made some specific questions, but im have my doubts about the high range power cams and the reliability of the engine.... with that said...

 

i dont mind revving to xxxx rpm, i just want the best from the engine.....

 

HOW are you going to rev to 9.5K on virtualy stock internals and make power.... have you looked at this https://honda-tech.com/forums/all-motor-naturally-aspirated-44/10-000-rpm-2234173/

 

i thought it was clear that i dont care about rpm, just making those cams to produce or do what they should....

 

not going to happen. Advertising is BS. Quite a few cams say "9000" or "9500". Dont believe everything you read.

 

Not in you'r OP you weren't. throw it on a dyno and see where you'r power drops off.

 

and overall do u think is going to work together well?

 

post the IM you list here and list the specs on your cams..

 

what brought you to choose Toda C cams? what is "polishing" the head going to do?

You gotta give us something to go on because it it appears you are just throwing parts at it then that means you havent done much research to know the parts will work well. What have you researched that supports the goals you are looking for?

 

Nope..more like 190 or -

 

thats what am thinking....

 

those CTR pistons in a GSR will be more than 12:1 compression. I specifically went with Standard B16 pistons instead of CTR to keep the compression DOWN to 12:1... CTR will be no less than 13:1 and now you're talkin race gas only. But my setup, b16 pistons .5mm oversized, titanium valvetrain and custom grind cam thats hardly as aggressive as stock ITR cams tuned with an s200 made 188whp at about 8000rpm. Revs to 9000 easily, but not making any power there. So if you actually put it together the way you say with those cams and pistons, it should make much more power than me easily, probly at a higher RPM, but have fun with that 7.50/gal race gas every fill-up.

 

Where is this 13:1 compression you speak of coming from? It's more like 12:1 and at most 12.5:1 with CTR pistons in a GSR. I personally ran this set-up twice now, once with P72 head and once with PR3. Both motors had measurements done and did not show anything over 12.5:1

 

is ported and polish and valve have some degree i cant tell, that head was able to produce 250 on a b20 sleeve of a friend of mine,

 

thats what i say, i also have my p72 head but im using pr3 to low compression a bit

 

wrong....

 

that makes me unhappy... :p

 

With the p72 head its approx. 13.08:1

 

interesting page!

I calculated with pr3 head and is 12.7 pump gas it is

 

I hope you have a good tuner. I dont run into bad gas.

 

i actually have a good one, pump gas is not to good here in DR , im thinking of mix 2 gal of 103 oct fuel and 4 premium fuel to ensure the quality....

 

The online compression calculators are to be used as a ballpark reference...it is in no way accurate. I only trust real world measurements of the actual head/piston/block whatever.

If i go off that zeal calculator, I am currently running 91 octane on a 13.83 CR motor? Doubtful...
