OPTIONS FOR FUEL&TIMING; TURBO KITS
OPTIONS FOR FUEL&TIMING; TURBO KITS
--------------------------------------------------------------------------------
I'm researching doing a turbo kit for my car, and have a few questions...
To those that have turbo S2Ks... How does your turbo kit deal with engine management?
The low-tech approach appears to be an upgraded fuel pump & fuel pressure riser, with stock injectors, and no timing adjustment.
The higher-tech methods tend to use upgraded fuel pump, injectors & AEM or E-manage to adjust timing.
What are some other approaches taken?.. from low to high-tech & in between.
Other than AEM or Greddy, how else could you adjust timing (lower-tech method)?
Thanks, Mike

wait wait wait... u can turbo and s2k?.... i read on s2ki.com that it was impossible because it was something about the ratios....so it CAN be turbo'd!?!?

For a guy who owns an S2000 you sure don't know a lot about your car. Yes, it can be turbo'ed and you are talking about the compression ratio. You can lower your compression ratio to 9:1 and install a custom turbo kit. There are S2K's out there boosting as high as 18-20 psi on the cars. Of course, you'll need to build your engine for it. EX: Forged internals, blueprinted, PnP'ed, and sleeves for high boost, bigger injectors, fuel pressure regulator, better fuel pump, custom hard piping for your intercooler and many other various things that I haven't listed.

And for a guy that doesn't own one, you seem to act as if you know a lot about it.
This isn't a ***** size battle here over who knows what....but when you use words like "need" and "necessary", you should use them with caution.
You don't "need" to use forged pistons and connecting rods. However, by doing so, they will withstand more abuse and leave a greater margin for error. Upgrading the fuel system is almost imperative when doing any kind of FI or extensive N/A build. Porting and Polishing is absolutely not necessary. But, when done correctly, it can help the air from a turbo or supercharger flow better.
One thing you didn't mention was something to control and tune all the. Engine management. All this good equipment is useless without it. You "need" one of these to extract the full potential out of your setup.
I have seen 1 s2000 turbocharged that only upgraded to 550cc injectors and was using an Apex-i VAFC. He boosted 15 psi. I couldn't tell you how long it would last, but, it's possible.

Re: OPTIONS FOR FUEL&TIMING; TURBO KITS (s2kDinesh)
I know its possible to turbo the car. There are kits out there for $4000-$7000 & higher. The difference in quality of components between a $4K kit and a $7K kit is huge. I'm putting together a kit myself, and am trying to find out what other people have done, and with what success.
The biggest problem to be aware of is the 11:1 compression ratio. Ideally for a turbo car, you want the CR to be in the neighborhood of 8.5:1, but without changing to "dished" pistons or a thick head gasket (both of which I don't want to do at the moment), you have to carefully deal with the problem via fuel & timing management.
What I'm looking for is other's peoples experience (550cc injectors + Apex VAFC + 15psi)... Sounds dangerous to me, but thanks for the input, ScreaminTeg

Re: OPTIONS FOR FUEL&TIMING; TURBO KITS (sportridermike)
Yeah...550cc's, and a VAFC sounds like KA BOOM! to me.
While the CR wasn't as high, before upgrading to an E-manage, I successfully ran the AFC 'hack' on my old Integra. But, I don't know that I would do that ever again.
without taking money into consideration, what kind of HP goals are you looking for? Are you going to race your car? Auto X it?
Just curious.

holy unneccessary parts list! Do you even know what bluprinting your motor means?? It has nothing to do with FI, same with PnP, sleeves, fuel pressure regulator, and forged internals.
Companies like Full-Race make turbocharging sound like it costs $50,000,000 to do it right.
What you need: turbo, wastegate, intercooler, injectors, engine management, BOV, and piping. Thats it. The reliability of your kit depends on your choices for fuel management and the person behind the wheel.

LOL this **** is hilarious... I ran 7.5 PSI on my bone STOCK D16Z6, however I used a Hondata for proper fuel and timing management. I later sold the engine, and the current owner is now running 10 PSI on the same STOCK engine, again using a Hondata. Call it luck, call it whatever you want. The engine isn't going to last forever, but you could build the above "Fast and Furious" style engine with all the three letter abrevations in the book and the thing might not even turn over depending on the shop (or person) that put it together.

Re: OPTIONS FOR FUEL&TIMING; TURBO KITS (TommyV)
Ehh... some people don't read, I mentioned 18-20 psi not 6 or 7. I'm not tryin' to dick the guy. My answer was yes you could do forced induction if you wanted to. Yes, I don't have one yet but I will soon. Gosh, its crazy how many people get all heated when they read someone else's answer. My apologizes to all if I offended this man in anyway.

Re: OPTIONS FOR FUEL&TIMING; TURBO KITS (ScreaminTeg)
I've already looked into the Inline Pro kit, and don't think that is the best engine mngmt approach. I don't plan to race the car... I want a reliable street-worthy kit. I think a reasonable engine HP goal (with no engine work req'd, including changing the head gasket) is 350.
Sorry to "bash" you guys that commented on other cars, but this is the S2k forum... what you did on some other car is not really applicable... I'm looking for boosted S2K experience. Thanks.

Re: OPTIONS FOR FUEL&TIMING; TURBO KITS (mp7235)
proper engine management is the AEM unit. It's plug and play and doesn't require you to modify your engine harness like other standalone units. There really isn't a cheaper method to adjusting timing. I don't know what else you are asking, but that sums up your engine management. Everything else depends on how much power you want to make, pounds of boost, and your budget.

Just becuase you've seen it done doesn't make it right. The AFC hack advances your timing and definitely would kill a motor at 15+ psi. Also for your friend with the D16 he cracked his ringlands cause of poor management. I had a d16z6 running 12psi daily and never broke a ringland. I also had an integra running 11psi daily and nothing ever came apart

In my experience, and I have been working on this car and my setup for over a year now that I can safely run up to 12psi on race gas and the ignition retarded down to 14 degrees at redline (midrange at 30 degrees then slowly dropping to 13 at redline). I tested running stock ignition settings and I got knock when I would get around to 8psi @ 8000rpm. Now I am *not* using a head gasket to drop my compression, so that is probably the determining factor between mine and Inline Pro's.
The compression drop will help up to 12psi, but not 20. The setup I had I accidentally hit (boost creep problem) 23psi and started knocking (on race gas) at 7500rpm @ 16psi. Luckily the EMS retarded my timing all the way down to 3 degree's to keep the knock under control before I was able to get off the gas (thank goodness). Since the dyno video I put out on the net, I have added a NX 35 Wet Shot on there to A. help with launching and B. to keep my EGT's down.
I donÂ’t doubt that there is someone that will be able to produce the numbers he is mentioning, but in the same respect without a standalone you are shooting in the dark. You have no idea if you are getting any moderate knock, or if the stock ECU is retarding timing when it registers knock. If it is infact doing that, donÂ’t expect your motor to last very long, every time it knocks damage is done.
The F20c does have forged pistons, and in all honesty it is a damn tough block. I put it though hell and back and the only incident I have had is when I over boosted causing a small scar on the #3 cylinder wall.
The only thing that I have a question is what Inlinepro is going to do when a customer buys this kit with the impression he can slap it on and go. There are going to be driveline issues that have to be delt with or there can be some very expensive consequences.
I really just stick by my word that if you are going to boost anything higher than 7psi or so, get a standalone and a wideband 02 sensor (preferably with a display). If InlinePro pulls this off, then good for them, but I just think that people are going to be blowing up alot of motors due to improper tuning.
Again, just my .02c

How can 12psi be impossible? There are tons of people running 12-15 on B-motors with just AFC and bigger injectors. This S has 550cc injectors AFC and fuel pump if you didnt know. It was tuned on the in house dynojet and he beats the car everyday. And yes it is all stock internals(S2000 has forged pistons stock BTW). You think he would put out a kit and not be able to stand behind it? Visit there website and look at all there accomplishments and see why they wouldn't risk there reputation to put out a shotty kit. Still dont believe, give John a call at the shop call at 703-644-1788 and ask away.</TD></TR></TABLE>
My mistake it was forged pistons. I skimmed through cause I was looking for something else. But that is what I came across and I'm not just pullin' this **** out of my *** its from this thread: https://honda-tech.com/zerothread?id=806426
If my research bothers you so much, I'm sorry, but I'm only here to do research in order to find out the potential behind the S before I buy it.

The F20c does have forged pistons, and in all honesty it is a damn tough block. I put it though hell and back and the only incident I have had is when I over boosted causing a small scar on the #3 cylinder wall.
The only thing that I have a question is what Inlinepro is going to do when a customer buys this kit with the impression he can slap it on and go. There are going to be driveline issues that have to be delt with or there can be some very expensive consequences.
I really just stick by my word that if you are going to boost anything higher than 7psi or so, get a standalone and a wideband 02 sensor (preferably with a display). If InlinePro pulls this off, then good for them, but I just think that people are going to be blowing up alot of motors due to improper tuning.
Again, just my .02c

How can 12psi be impossible? There are tons of people running 12-15 on B-motors with just AFC and bigger injectors. This S has 550cc injectors AFC and fuel pump if you didnt know. It was tuned on the in house dynojet and he beats the car everyday. And yes it is all stock internals(S2000 has forged pistons stock BTW). You think he would put out a kit and not be able to stand behind it? Visit there website and look at all there accomplishments and see why they wouldn't risk there reputation to put out a shotty kit. Still dont believe, give John a call at the shop call at 703-644-1788 and ask away.</TD></TR></TABLE>
My mistake it was forged pistons. I skimmed through cause I was looking for something else. But that is what I came across and I'm not just pullin' this **** out of my *** its from this thread: https://honda-tech.com/zerothread?id=806426
If my research bothers you so much, I'm sorry, but I'm only here to do research in order to find out the potential behind the S before I buy it.

Research is fine and very good, BUT you shouldn't be answering questions when your not sure of the answers. This is how misinformation is spread on the internet.
