How much will it take
 

Lets start from the beginning. I have an 88 crx Si that was boosted using a 14b @ 8-10 psi 11 afr on stock internals with no problems. But then I got in some trouble and will be walking for 6 months.

In that time I want to build a new motor for my car and the one I chose was a d16z6. 8-10 psi was great but I want to try to get more. But I don’t have the money to sleeve the motor. So my question is how much boost can I run safely on this setup?

D16z6
Stock crank
Eagle rods
Block Posting/blockgurard (which is better?)
Cometic head gaskets
Forged pistons (does anyone know if Suzuki Vitara pistons are any good)
450cc injectors
Intercooled
Crome for tuning running about 11.5 afr

i whould say 12-15 psi if tuned really good

Re: How much will it take
 

thats not even worth building a motor for imho....id run at least 15+

Re: How much will it take
 

fyi, vitara pistons aren't forged.

Re: How much will it take
 

fill your block instead.

good 500 dollar forged pistons

and run 20+ psi.

I'd rather have the D16A6 you run now, and fork out for some oversized valves and a mild cam.

Both suck dick. Do you like to pay to suck dick? I didn't think so. As other people are likely to tell you, sleeve the block if you are a richman and fill it with epoxy if you aren't. Or maybe just fill with epoxy regardless of your budget.


When you absolutely positively have to pay more than you would for a stock headgasket, but get the exact same thing as the stock headgasket.


Limiting yourself to 300 whp? Not that a 14b will get you much past 240 whp...


What's wrong with Turboedit, and not fooling around with an $$$ OBD1 conversion? You like to complicate things and spend time working for no reason? Personally, I like to spend my money on beer, and my time on drinking it.


I'm shooting for 300 whp on a single cam without "intercooling." D16A6 block, Z6 head, GX pistons, and milled LS connecting rods = 12.2:1 CR. .60/.63 T3. DSM 450cc for fuel, secondary fuel rail with stock Honduh 240cc injectors run to an electronic water injection controller courtesy of Dan at www.myo-p.com. YAAAARR!!11 As soon as the goddamn machinist gets done with the engine I'll lay it in the red hatch... should have less than $1100 in everything, including the car.

Boost? Water injection? Secondary injectors.....and no I.C.? Dude you got balls that clank...

Can be done, it's just the 12,2:1 CR I'm worried about!!!

Re: How much will it take
 

Air is not very dense. However much heat you take out of the incoming charge, really, isn't a whole lot of heat.

Water is pretty dense - pick up a heavy ass pail of it sometime. The energy required to heat it from ambient temperature to boiling point - which is a ---- ton more than 212 deg F thanks to pressure cooker compression - is a LOT more, if injected in significant quantity, than you remove with a shiny homo-magnet intercooler.

Trust me, no balls involved. Pure intellect.

Sir Harry Ricardo discovered, oh, about WW1 era, that after a certain volume of water was injected into an engine that the engine's cooling jacket was no longer used to shed heat. He took a brand new $$$$$ radial aircraft engine, dropped all the coolant out of it, and cooled it solely by water injection. Ran it in the lab for something like 200 hours of wide open operation. Upon teardown and inspection the engine turned out to have suffered completely normal wear and tear for the amount of time it had operated - still brand shiny new. OH NOES!!!!

Now, the only reason why everybody doesn't run water injection is because it's another container you have to fill. Oh, god. Pouring free water into a reservior everytime I fill up with $3/gallon 87 octane, in order to have a knock limit and engine thermal safety orders of magnitude greater than a mere $500 intercooler it took a sawzall to clear enough space to fit, is such and inconvenience. I am such a Christian martyr.

Guys, don't try to pour water at home. Leave this to experts.

I'm talking about keeping my coolant jacket AND running water injection. Balls of steel? Try total safety.

Intercooling is like an MSD - it gets the riceboys hard, accomplishes very little worth the price and effort. You meet LOTS of really nice, excited young men, with a really big intercooler. That's what it's all about, right? Just like OMG V-TECH Y0! you have to have it to get the respect of strange men you haven't fucked yet.

heheh...

Someone has done is Homework!!

I can't wait to see this! I was something i was thinking of doing in the past.

Re: How much will it take
 

nice write up joe.

oh and darton MID sleeves are pretty nice. i've delt with darton for like 900.00 you send your block off and they will resleeve it for you. i got mine back in 3 weeks and never had any problems with it. it was worth it to me. i'm sending my new block to them to. but they are giving me a deal this time ;)

Me thinks i have been wrongly accused of I.C. envy...?

Re: How much will it take
 

wow!

Re: How much will it take
 

Nah, I was razzing the performance aftermarket in general. You should see how HUGE and SHINY my IC is - the one in my sig that I can't fit.

Been calling BOVs, especially RFLs, Riceboy Mating Calls for some time now. Now ICs are going to be "Homo Magnets." Anytime the Riceboy hears the mating call, or sees the IC, they absolutlely positively HAVE TO BE YOUR SPESHUL NEW MALE FRIEND WITH POSSIBLE LONG TERM RELATIONSHIP.

Yup, no IC, and I think I'm routing my BOVs back into the intake ducting. I don't want speshul male friends - I just want it to really really hurt when I break it off in a built domestic or a Honduh-Tech Super Stunna. The dents + dirt + rust give the car it's trailertrash mystique... why ruin it with the over the top stuff, eh?

Re: How much will it take
 

Mr.Davis. I'm curious about your planned manifold and wastegate setup/design? I also don't understand raising the static compression ratio when the current school of thought swings in the other direction, espicially with the use of pump gas.

Re: How much will it take
 

With a pump gas knock limit of ~350 whp on a 10:1 CR D-series, in traditional air-air IC fashion... pushing 300 on a 12.2:1 CR with liberal water injection isn't going to be that large of a stretch. To make really big power, at some point you HAVE to have a bigger combustion chamber, period, but I'm not there yet.

The water will keep things cooler than an air-air IC setup, so my pistons will remain strong instead of becoming soft as aluminum is wont at higher combustion chamber temps. The water will also raise knock limit considerably, preventing the pressure waves/spikes that cause softened, overheated aluminum ring lands to break.

I'm running GX pistons on the SOHC, because they fit on the ends of the LS rods with minimal ------- around. It's cheap. It's expedient. If I was made of the dollars, it would be ~9:1 CR, have a bigger turbo, and I'd be pushing for a bigger goal. As it is, I just want to overspin a .60/.63 and watch it die after 7000 miles.

O, i get it now.

Re: How much will it take
 

Dude you are way way too smart for this ----, drop a resume at N.A.S.A and get their ---- fixed so we can actually go to mars and build drag strips there instead of the lumpy ---- i have in Canada.....man i need a life....i swear to god i spend more time on this site and im pretty sure my kids forget who the hell i am, cant wait to get my junk together so i can just not come home......
