Frank Build !

[K20z3_Si]

Hey guys hows it going. I just picked up a k24 block. I'm doing a all motor build on it. No nitrous boost nor supercharger. m interested in maybe boring over .20 or .30 I don't want to sleeve it. If i could have some advice on what do do that would be great ! so far this is what on the list

- Eagle rods

- Wiseco Pistons 12:1 Cr

- Acl Bearings

Shoot me advice on boring it over... if so what CR should i run on the piston. Thanks for all the help

[K20z3_Si]

Nobody has any experience with this ? I'm sure 1 out of the billion users here has built a k24 up lol . I just need to no is it going to be worth boring it out rather than just honing the cylinders at normal bore size. Hope someone can help me out on there opinions !

It's too early man. Lol It's 1:30am here in hawaii so it's what.....7:30 in Ohio? (i'm originally from Ohio) There have been a lot of people doing K24 builds. I'd suggest looking through some of the other posts in the All motor section.

What are you power goals? You say your staying n/a right?

[Gunner]

If you do a search for k20/k24 you will find about 100 plus threads on it.

[brado]

If I may make a suggestion? Change to cp pistons 12.5:1 and Carrillo sa-pro rods. While both of these are more expensive than your current choices, it is worth it and you shouldn't put a price on a good engine build. As for bore you shouldnt go past 87.5 mm without sleeving. I hope this helps, btw this what my build is

[K20z3_Si]

Ok thats kool guys i have searched and coulnt really find what i was lookin for. Yes it was 7:30am here lol i was getting ready for work haha. Ummmm my power gains im wanting are around 300+whp. im currently at 237 at the wheel with just a built head and spporting mod. Im hoping to get more than 300 with a fully built motor. Ill do more searching but thanks for the responces guys !

[bulliedog]

Your going to be atleast 12:5:1 comp with a very aggressive cam. Either a ported RBC or Skunk2 manifold. Bigger TB and a 3.5 air intake. A good flowing exhaust. You are gonna have your work cut out for you. Not many have hit the 300 hp mark on a K20/K24 build. You can PM OldSchoolFA5 and see what he did for internals. He hit 309hp/223tq on 93 octane. It can be done.

[K20z3_Si]

Man i totally told u guys wrong. it was 12.5:1 on my pistons. My bad. Yes it can very well be done. I have supertech internals ( dual springs, retainers, seats ) Skunk2 stage 2 cams. Im prolly going to do some valve work while my head is off or something like a port and polish.

You will need way more aggressive cams, something like Drag Cartel stage 4's to hit the 300 hp mark. With SK2 stage 2 you might hit 260hp- 270hp with the right supporting modds. Of course depending on what dyno your on. most likely it's not worth porting the K20 head. I would put the $1500 in something else.

[reid1980]

Another build to look at is the black widow build. 13:1 compression pistons and Im not sure either stage 3 skunks or stage 4 dc's. They also hit the 300+ hp mark.

[K20z3_Si]

Ok yeah i wont wast the money. Ill do something worth the hp numbers !. I go get the block tomorrow morning. I'm going to ask some questions regarding the 300+whp. The shop i go to is really good very very legit. Ill do some asking and see what he says. Ill post what is tlked about then we can go from there. Thanks for the advice guys ! ill chime in tomorrow after noon.

[K20z3_Si]

OK so i decided to go up and get the motor today. The block looks great. I was asking what do i need to hit the 300 mark. Basically he said something along these lines. RRC Manifold, Port match the TB, Mild Head work, Stage3 cams, and then of course building the block up. Plz add in whatever u can to this. Im not sure if i want all motor or build it for spray.

[K20z3_Si]

The More looking that i do im NOT spraying. Its going to be a all motor i don't want to put all this money into it and some go very wrong the first time i spray !. Here is what my shop got together for me

1st...

Clean/Boil Block
Bore/Hone Cylinders
Clean, Polish, and champher crankshaft.
Resurface block

2nd

Purchase Eagle Rods
Wiseco Pistons 12.5:1 Cp
ACL/OEM Bearings- To get exact bearing clearance

3rd

Short Block Build
( Spec main bearings clearance and adjust, rod bearing clearance and adjust, Crank end play, Piston to wall clearance, blueprint sheet, Front and rear main seals. oil pump water pump )

RRC Manifold/ Skunk2
Port Match TB/ J35
Stage3 cams Larger injectors ( 410cc currently)
Walbro 255 pump.
Mild head work ( Not sure what to do )

Plz give your .02 on this i need all the help possible

[reid1980]

Also throw on the k20a2 oil pump. Go with a larger tb than stock like that j35 or skunk2. A header with a 3" collector and a 3" exhaust and you'd be pretty close. Engine hp would be 300. Oh and obviously flashpro to tune.

[Strate L O S S]

Looking like a good build.

[K20z3_Si]

Kool ! Yeah im looking at headers and i cant seem to find one with a 3'' collector. everything is 2.5'' def opening it up tho ! Yes the j35 is the one im getting. Anyone ever port and polish there stock RBC ?

[Will06SI]

Go Power offers custom headers with a 3" collector or there OTS 575 header with a 3" collector contact them asap.
