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!!!

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...
