i want to build a 400hp ef civic for weekends and the strip and would like some input on wether im on the right track so far

ef civic
peakboost ramhorn kit with gt3076r 38mm wastgate
b18c4 stock block(its and engine we get in the uk and i think its very similar to the b18c1)
b16a2 head with p+p and uprated valvetrain(currently searching info on supertech)
type r cams
cp piston 9.0 81.5mm
eagle rods
arp bolts
oem oil and water pump
750cc
2.5 motorola map sensor
tuned with crome

obviously ive got to get stuff like brakes and clutch etc but do u think im on the right track for making that power and am i right in saying the block dont need resleeving for 400hp or have i got it all wrong

dazcivic

bump for a new day

dazcivic

o yeah this will be on 99 ron uk pump fuel

tony413

your on the right track an yes the C4 an C1 are basically the same in specs.
some things your gonna want to look at is 1000c.c. injectors or more to be safe
aeromotive, eldon, or walbro fuel pump with ATLEAST -6an lines those are the same size as stock.
some people are gonna say get different rods but eagles with big bolt arps are fine.
other than that your in good shape and sleeving the block might be needed search around

dazcivic

is there a problem with eagle rods then? i chose chose them as they are a name that pops up alot
wats the reason for changing the fuel lines ?

tony413

no reason at really the stock lines are good up to 500hp an are -6AN. if you want some add bling go SS. also eagles with big bolts are just fine, its just that there small bolt rods have a bad rep of not holding up to power an abuse to well. i rate the forum favorite as follows: pauter, manley, carrilo. the carrillo's come in 3rd cus of the nice $900 price tag

those eagles are fine like tony said.

walbro 255 isnt on the list though im sure you are likely getting one.

supertech makes great valvetrain. i wouldnt bother porting the head but thats just me.

fast2camciv

pistons, rods, arp's, 750cc, 2.5bar map, walbro 255, tuned on crome and pump gas will get you 400. the rest is just trivial...keep it simple.

dazcivic

cheers guys
yep a walboro is on the list thats in my head just forgot to put it in my post
i read somewhere that eagle rods come with arp bolts ,is there any truth in this or do i need to specify arp bolts or get arp rod bolts seperatly

as for stuff like gaskets ,bearings etc that will be used in the build do u recommend honda only or uprated or other manufacturer oem spec

dazcivic

i think i will try and find a type r head cause then it flows better as stock and has the type r cams
do u think the type r valve train is up to the job or replace for supertech stuff
even if i replaced for super tech i could recoup some cash by selling the type r valve train
id like to rev it passed 9k without any issues

tony413

bearing = ACL
Gaskets= cosmetic
also if you did get a type r head you should be fine with that just stock. the B16B and B18C5 an B18C7 are the ways to go for heads. if you plan on keeping the head you have now just get valves, springs, and cam/cam gears that will cost les than switching the entire head

0morgan@synapse motorsport

gasket=oem

if you want to rev to 9k i would just upgrade the valvetrain on the head you have now

CivicVX94

use oem bearings. acl bearings are generically sized and only come in two different sizes for each engine-standard and race. use oem Honda bearings that are properly sized to be on the safe side. don't just go with standard acl's or honda pinks....

dazcivic

been pricing things up and it looks like im either gona have to cut back on certain things like the type r head and a few other things ive got on my list or im gona have to cut back on the build for the time being and just run the peakboost kit on the stock block
i have also thought about piecing a kit together myself but im a little worried about any fabrication there would be and mainly welding as although i can weld i only have a mig and it certainly wont be as pretty as if i bought the peakboost kit
also im gona need to try and by everything from one place so i can try and get a deal on shipping cause otherwise the shipping costs really add up and use a bit chunk of my budget

any cost cutting tips u can give me would be great and any one stop shops that aint to pricy

and i hope this dont sound like im being cheap cause id rather sacrifice power than sacrifice the stregth and quality of the products cause i want it too last and lets face it even though 400hp is gona be fast 300hp in a sub 800kg ef civic aint gona be slow

tony413

the old saying "speed cost money friend. How fast do you want to go?"

keep your block and keep your head
get type-r cams or crower stage 1 cams
get valve springs and valves
eagle rods and arias pistons combo is like $750
stock ECU an hondata, crome, or uber ( your pref) $50-$400
catch can set-up
traction bars ( your pref )
just the simple things take you far people hit 11's with only the 275hp range

dazcivic

i aint got any of it yet as the car is a d16 twin cam
so i aint got the block or head and here in the uk i could get a type r head with cams and valve train still in it for alot less than i could get a b16 head and type r cams and a good valve train seperatly

some of the pricing ive done was guess work such as £100 for water pump £100 oil pump and i over estimated on alot of stuff and im sure they will be cheaper and prob even cheaper if i got everything i could from america

£1= roughly $2

why would you want to rev that high, rpm = ruins peoples motors. if your going to do this you might want to lower the compression a little. i don't think that turbo's effeincenly range goes that high on a b18 you might want to look at the compressor map for that turbo and do some math before you drop all this money into parts. from what i am looking at your car will be great till 7500 with the turbo after that its out of the range for usable power

dazcivic

any links that really simplify compressor maps

tony413

check my sig its all there an very nicely put to laymans

^^ Listen to the man, he knows what he is talkin about.

For a hg you can use oem or cometic and bearings you can use oem or acl. Your choice. Just make sure the builder knows wtf he is doing. That is where most of these builds fail, not in the components.

Maybe you can explain what you mean here. The gt3076 comp map (yes just the comp map without taking into account the turbine curve), flows ~50lbs/min efficiently. Why would he not be able to flow 40lbs/min efficiently on this turbo? Maybe am missing something here and you can enlighten me.

Just wondering what exhaust you plan to run?

dazcivic

thermal r+d if they do em for the ef or possibly a custom
and im even trying to find out if it would be legal to run it straight out the side of the bumper
