LS head build
 

tell me what u think or what i can improve

its a p75 head
gonna run stock valves with stage 2 crower springs and retainers
with crower 403 all motor cams
gonna port match the head to the gaskets so maybe a 1/16 of an inch port maybe lil more a then polish it

them polish the intake many run obd1 injectors and aem fuel rail and regulater


ganna run it on s300 hondata with a tune

just looking for opinion let me know what u think

:thumbup:

Re: LS head build
 

but what are your plans for the block?

Re: LS head build
 

im building an other block everything stock except ganna run p30 pistons for high compression

i know a stock block with a good tune can high rev at 8500 im planing on running that with the hondata and a good tune

Re: LS head build
 

and a block guard

Re: LS head build
 

ok...you can slap that head on a b20 block, and if you happen to be on a budget, use rs machine "itr" pistons....youll deff make good power with those pistons and your compression should be 11.5-12.0 depending on headgasket thickness, milling of the head and deck height...

i used rs machine pistons on one of my old allmotor builds (all motor b17) and they were great. never had a problem with them and they were the p30 pistons also at 81.5mm bore...i used them for just a little more than a year before i sold the car.

i plan on using rs machine pistons on my b20vtec build.

Re: LS head build
 

i dont understand why this is in the force induction forum

if the non vtec head is anything like the vtec head, its not recommended to run stage 2 cams or in some case stage 1 cams on a stock valve train. do you think that valve train can take the revs up to 8500 with bigger cams? get rid of the horrid block guard, its not going to do any good for you...at all.

Re: LS head build
 

I'm confused

Re: LS head build
 

lol i totally overlooked his intro post about stock valvetrain...

highly recommended to upgrade valvetrain!

and someone relocate this to the allmotor section

Re: LS head build
 

Don't worry, I am as well.

Re: LS head build
 

He's just running stock valves
He's using Crower valve springs and retainers

You people suck at reading

Re: LS head build
 

doh!!!

Re: LS head build
 

An ya. I know. The.valves can run all stock turbo with a good tune. pushing 8500 rpm

but that what's the valve springs.and.retainers.are.for. to back up the.valves so I doing.visit a.valve

Re: LS head build
 

8500 is pretty risky with the way the rockers are designed on the non vtec heads. I would keep it below 8k.

Browse over to the all motor forum and check out some of the non vtec threads and the p8r thread. There is some good tech buried in them.

Re: LS head build
 

What is your power goal? That piece of information is step one.

I could list a number of things that you could improve if your looking to make 800WHP but that list would be different if you're only looking to make 250WHP.

Re: LS head build
 

And move this from forced induction....

Re: LS head build
 

Ya around 250 who for.now

Re: LS head build
 

While I'll say Im not particularly fond of revving that higher, I did it all summer to 8750 and the engine was still making power.

Re: LS head build
 

so the engine can hold up to high revs it a good tune

Re: LS head build
 

Is this a damn turbo build or all motor?

If its all motor you will never make anywhere close to 250 whp unless you spend mega dollars on a B series or do a k swap.

Even the set up you are talking about, if its going to be an all motor b18b, will be a slow turd with itr pistons and a cammed LS head. You be getting your ass handed to you by stock block boosted single cams, so why bother?

Do some more research and figure out what's even worth doing, then ask questions.

boost ain't everything. I've.scene Portman build rape boosted single cams bro so learn ur Shit. it's a lot.better to build ur Shit than just slap a cheap eBay turbo and.call ur Shit .fast.

I putnthis.on the wrong foram. my mistake.

Re: LS head build
 

To most people, the money necessary to make all motor power on a D series engine just isn't worth it when boosting a D series can be done cheaper. Knowing simple economics of making power is knowing ones shit.

Re: LS head build
 

Trolled.

Re: LS head build
 

Np thsys dimb thats jist the cheap way of making power its not hard to slap. A turbp on tobs engine and cann ur shit fast.


Now.building a motor that rapes does so called. Fast turbod. Motor. Ya thats a good thing dont try an dnplay being a cheap ass off. Nd how did. Dis bwcome abot a single cam.

Re: LS head build
 

Ad to talk about.money my hea dbuild is only costing 600 bucks with crower everything. Brand new


How much does ur turbo kit run.a full turbo kit all the pipping.the turbo the wastegat blowoff valve injectors all that
Unless ur.buying a cheap ass ebay turbo ot buying. Used shit...... mines cheaper

Re: LS head build
 

Speak fucking English
You make no sense whatsoever.

And how's yours cheaper?

He was saying that even the most basic of turbo single cams will destroy an all motor ls?

Hell I can make more power with a built all motor VTEC single can than an all motor ls
