ok, i am starting on a engine. i knwo that it is going to be ls/vtec, but what i want to know is, what is a reasonable amount of HP to expect out of a n/a engine?

plans, je 12:1 compression pistons, crower rods, stock crank
head will be p/p'd, honed to a mirror finish, o ringed copper head gasket(will not blow), bigger valves(probably 1 mm) skunk 2 stage 3 cams, portmatched intake manifold(custom sheet metal-power bling) and all the regular boltons-2 inch headers to a 3inch collector(4-1), bigger throttle body, and all the basic needs. nitrous may be an option, but what can i expect with out? please give me a reasonable estimate, cuz im kinda thinkin turbo too.

 

310 whp. tell all your friends.

But seriously, the build list seems a bit silly. settle for something realistic and simple unless you really know what you are doing. otherwise go turbo.

 

why is this silly? my brother in law will be assisting me along with his cousin, who built a motor just like this, but he never dyno'd it or ran it to get hp or times, but he was able to run a 200 shot and it did GREAT believe it or not , and they knows thier expletive. im just wondering what i can expect without nitrous, and with if you want.

 

bump for something or other

 

4) E-Racing/Bench Racing/Guess my 1/4 or HP
There is no place for it here, it is not productive, frequently leads to arguments, and is generally pointless. Go find a dyno or a drag strip.

fine, hows this, does someone have a similar setup that they have dyno'd or ran times. if so, what hp/times did you get? hows that?

Let me break this down.

12:1 compression. thats arguably threshold of pump gas, better tune it carefully. but you never mention tuning or ecu at all.

p&p head. who is doing the work, are they experienced in b-series. also, why run the bigger valves on a 1.8? re you really expecting to flow that much air

o-ringed copper headgasket, wont leak. o-ringed block you mean? has oem gasket been giving you troubles leaking before?

honed to a mirror finish. what exactly is that. fine stone like 400 or so? what makes that great.

custom sheet metal power bling. again, who is doing the manifold work. are they making the plenum size , runner length and diameter to match your motor and powerband?

all the regular bolt ons. ?? please explain what is a regular bolt on

2 inch headers with 3 inch collector. are you saying 2 inch primarys?


I'm not trying to flame, but this sounds like a wish list from somebody who doesnt understand the modifications. I hope your motor builder is very knowledgeable and can come up with a good combination.

of course it will be tuned, and yes this is my first engine, i am somewhat knowledgable in the honda world. i may not use the same names for things that you do, but i am probably from a different part of the country than you. tamato-tomOto(cant sound it out)

ecu will probably be hondata. again, im still researching for myself, i know what CAN be done, just not what SHOULD be done.-taking advice from people that have done this.

air dynamics are air dynamics no matter what motor. the shop that is doing mine is the same shop that does Chriss Tuttens mustang-Rebel Machine in Columbia,SC. then sending it to california to get it honed. they basically take medium grit rubbing compund and force it through the head at a high preassure, then go higher and higher till it looks like the Dart gsx heads. its called extrusion honing.

the i.m. is also being mad by rebel machine so it will match. about the powerband and all that, i say w/e

you o-ring the area around the combustion chamber on the head, then you use a copper head gasket. wont blow. the guy that is helping me did the same, and ran a 200 shot, didnt blow the gasket, fubar'd the pistons.

regular bolt ons, ignition, header, exhaust, injectors, fuel rail, fpr, regular bolt ons, the basics, the things that everyone does.

2 inch header, 2 inch primaries, w/e you know what i mean, tube coming out of each cylinder is 2" and they collect into a 3 inch section, might go with 2.5 instead though, we'll have to see.
