need some advice (building my motor up)
 

ok, so i am rebuilding my b18b. i am going to be putting SRP 8.8:1 or 8.4:1 pistons(havnt decided) darton sleeves and tuner toys h-beam rods. plus a guard block. my question is, how much horsepower do you think that setup will hold? i might be thinking about nitrous in the future, so keep that in mind. so what comp ratio should i go with. 8.4 or 8.1, i want to run somwhere around 20-25psi SAFELY on crome. is this possible? thanks guys

and if you have a setup that you have done in the past like this, post up what you used and what you accomplished with it! THANKS!!

Re: need some advice (building my motor up)
 

with a block guard AND sleeves, its gotta be good for at least 1000hp. sounds like you need to learn a hell of a lot more before you go taking that motor apart.

Re: need some advice (building my motor up)
 

like what

Re: need some advice (building my motor up)
 

A blockguard is used as a substitute for sleeving for those lacking the money.If your going to spend big bucks sleeving you might as well get something better than SRP&tunertoys combo.

Re: need some advice (building my motor up)
 

another words u cant use a block guard with sleeves O0

and as to running 20-25 psi is fine on either 8:4 or 8:1, just use a good tune, i would prolly even go a little higher but you gotta choose what u want you might want to do a little more research before commiting to this project

Re: need some advice (building my motor up)
 

i thought a block gaurd was just extra support for the sleeves. I dont want to spend BIG BUCKS, and thats why i am choosing to go SRP and tuner toys. whats the matter with there stuff? I would like to make UNDER OR AROUND 500hp. I think that that 450 is a Goal to reach. I am thinking of just going with 8.0:1, thats a pretty good compression ratio for my wantings right?

Re: need some advice (building my motor up)
 

and yes i need to do more research i know, but i was just getting an idea, and i would still like to know if anyone has similar buildups and could let me know what they did! thanks

ALSO IF YOU HAVE A BUILT TURBO MOTOR USING UBERDATA, CROME, WHATEVER, YOUR INFO IS GREATLY APPRECIATED! THANKS!

Re: need some advice (building my motor up)
 

block guards help protect stock sleeves

Re: need some advice (building my motor up)
 

8:1 is low to me....id go with 9

Re: need some advice (building my motor up)
 

with 20-25psi? if anything i would go max 8.5....right? 9 just seems to high to me

Re: need some advice (building my motor up)
 

Why sleeve it and then throw in a gay block guard?

What the ---- does PSI have to do with anything? Sure, it's possible, not with the stock MAP sensor but whatever that's not important.

I think the fact that a lot of factory boosted rides run sub 9:1 compression would lead me to pick the 8.4:1, but I havn't done enough reading on it yet.

Some people don't like SRPs, Tuner toys rods are same quality as Eagle stuffs.

If you're looking for 500whp I think you've got a lot more thinking to do than just deciding which set of rods and pistons you're going to run.

If it were me, I wouldn't bother ------- around with sleeving the block or running a guard. Pistons and rods, and plan the rest of your system out well.

Re: need some advice (building my motor up)
 

I don't even know if it's possible to Sleeve and Block Guard without making a custom block guard. The overall diameter of the sleeves is usually bigger, not allowing you to slip in a block guard in the water jackets!! If you want sleeves. you'll pay for it, and it's not cheap. IMO Block Guard are crap. Best would be closed Deck Sleeves.

Running sub- 9:1 CR is for -----s who don't know how to tune or Real Cars running Helacious Amounts of boost. Like 29+psi. You will need the extra psi to make up for the lost power from CRs Stick it around 9.1:1 and you'll get a nice spool time, and yet a safe enough motor with a good tune. Look how many B16s and B18s ae livig making 300whp stock at about 10.5:1CR. It's all in the tune!

Most Factory Boosted cars run low CR to cover te warrenty asses because they know that the customer is oing to jack the boost up, which the car isn't tuned for. If the car is at 8.5:1 or less, not too much risk, if it's at 9.1:1 or slightly higher, raising boost without re-tuning mean alot of warrenty claims that they would turn down anyways!!!!

Re: need some advice (building my motor up)
 

See, I don't buy the lost power/spool time crap. Of everything I've read, the people who actually run the lower compression setups don't have a problem with them.

I'd much rather drop a point in compression, jack the timing right before boost and run a few more pounds if that's what it takes to hit my power goal.

I think low factory CR is due to shitty gas, and shitty drivers. I was just illustrating the point that most factory boosted cars can hit some pretty nice numbers stock blocked, with minimal to no tuning.

I can't decided whether to keep my ZC stock, or have a spare set of A6 pistons dropped in. I'm going to be running water injection, so I'll probably skip the piston swapping, but I'd like to do it just to have some personal experience with a low compression car.

Re: need some advice (building my motor up)
 

When I was starting the parts collecting for my DOHC ZC Build I was contimplating 8.1:1 CR. EVERY and I mean EVERY Person I asked on here and other places say that with the ZC(becuase that what I was asking about) and on some older motors, dropped from 9.5:1 or higher down to Low 8:1 CRs and said they wished they kept the stock CR area, and that some of them even wish they kept the stock piston setup. They hated the feeling of the lower CR.

Re: need some advice (building my motor up)
 

as for the cr. i would go with 9.0.1- 9.2.1 nice spool time and not laggy as hell
eagle rods endyn pistons the rollerwave ones
remember that head work is very important when you have a shity flowing b18b head
get it ported and polished nice 5 angle valve job ,and get the valves back cut 30* after the first 45* trust me this helps out alot on Ls heads
get that block sleeved dart or earl its your choice im getting a dart block

it goes like this you want to play you got to pay
im going to dump around 4 grand into my next motor how much you spend and how many short cuts you take is up to you

Re: need some advice (building my motor up)
 

If you have to ask some major questions(ie. Is this compression good for what I'm looking at?), you might want to do a lot of research. 450 HP is a lot to pull from a B18 4cyl, especially without droping a wad of cash into it. Sleeves are going to be quite expensive, and if you're going the extra mile you might as well upgrade the rods and pistons. Email the rod & piston companies and ask the rated HP or the items you're buying. They might not be rated that high.

Re: need some advice (building my motor up)
 

Sleeves and a blockguard, ------- hang yourself you idiot ::)

Re: need some advice (building my motor up)
 

I can get darton sleeves for around $100 a piece, and still no one has told me why the srp pistons are so bad. I think i am going to go with 9:1 CR with a thick headgasket to drop it a litttle. I mean, if i have new pistons, rods, sleeves, it should be able to withstand 9:1 with some good boost.

Re: need some advice (building my motor up)
 

Add about 5-700 for machining the block for the sleeves. Around here the average price for sleeving a olck is 900 total.

SRPs aren't bad. They are not great Race Piston, but on a mid-level DD they are fine. That's why I'm going to use them.

Re: need some advice (building my motor up)
 

Definately go with 9:1. D series compression calculator put my car at 8.8:1 with vitara pistons, then i had my block decked .026" Turbo spools just where it used to, but i probabaly only dropped a half a point of compression.

Re: need some advice (building my motor up)
 

jon ever since you turboed your car you havn't been very nice to the nublets

Re: need some advice (building my motor up)
 

Don't ---- around with thick/thin headgaskets if you're buying pistons, you're spending money on this thing, spend it right.

There's no doubt that sleeves/rods/pistons make a good combo for high boost, even just piston and rods are good to 500WHP if you can find someone who knows how to tune. The problem becomes making the rest of your setup work together properly to hit those numbers with some degree of efficiency and thus reliablility.

Re: need some advice (building my motor up)
 

can someone than direct me to where i can find info on building engines? because i thought all u needed were, APR headstuds, some head work to match up with the sleeves, copper headgasket, new darton sleeves, low comp pistons, TT's rods, new main bearings, what else do you need? do i necessarily need to beef up my valvetrain if i am going to stick with the stock redline?

Re: need some advice (building my motor up)
 

You can leave the head alone if you want. But with a LS being such a shitty flowing head, you probably won't want to. If you want to take it eas at first and do no machine work to the head if it's no neccessary, just do cams and gears. Depending on your cam decides whether you need better retainers and springs. Normally if your not revving higher you won't but if you cam has a HUGE lift you will.

When mine goes under the knife, which is right now, it's getting just some re-grind cams, JG Gears, and a Intake Manifold. I might Port match the head, but I heard toss ups on whether you can do this with the Vavles in or with them out. I don't want to dissassemble my head this far. So if anyone can clear up this please do!

Re: need some advice (building my motor up)
 

I wouldn't say the LS is a "shitty flowing head", but a nice set of cams/springs benefit it nicely in keeping the powerband up in the higher rpms. VTEC is for faggot ricers and people who like a nice idle.

Just copy this guys setup and like Evans says in it, get bigger injectors and a good clutch.

Really, that's all 99% of people do, look at HMT, 90% of the setups are the same, because people see what works and use it. Can you do it all a better way? Probably. Can you do it copying somebody else's setup? Definately.

Re: need some advice (building my motor up)
 

Ha, a lumpy idle is way nicer then a smooth idle!!

Re: need some advice (building my motor up)
 

Right on

Re: need some advice (building my motor up)
 

Lol, judging by this thread this build is never going to ------- happen. I'd say do some darton sleeves, with a blockguard and some block filler.

Re: need some advice (building my motor up)
 

^^^
Nah, at that level you might as well fill it with cement!!!!

But ya, I sort-of have te same feeling as Whitey

Re: need some advice (building my motor up)
 

It may never happen, but maybe the info will help somebody. Plus I just wanted to say faggot ricer.

Re: need some advice (building my motor up)
 

this will deff happen. i want to have it built by around may. so i am going to piece it together over time so that i will have enough money for it. plus its christmas. from all the relatives and parents i get around a grand. so i can do whatever i want with that. thanks

thanks for ur info too minor threat, finally a person who gives me a real answer
