So, this just happened.....

There was a much heated debate here before about CTSC causing a catastrophic failure. There's was an East coast guy also that cropped out because he didn't have a stand alone nor FIC at the minimum.

Really sorry to hear Jinks. I've blown up a car before and it was a sinking feeling. You seem to have a great attitude about it and that's the most important thing IMO. Hope the news gets better as you investigate.

Well Jinks add me to the list of those who didn't like seeing this. Hope you figure out a good solution for you.

I'm just your lower than average intelligence person, but I don't buy into all of the fueling debate anymore. Sure it can be done far more efficiently IF you have a fantastic tuner. I understand detonation is a killer, but I don't know if there's a way to definitively blame your failure on that. All of the NSX specialist in the game know that blowing the ringlands is common with the factory pistons. The fact of the matter is you and many others have 20ish +or- year old engines with a good number of miles, cast pistons, and god knows how many heat cycles. My view is that boost is a liability no matter how it's done or fueled on old stock internals.

I've been boosted before and it was a riot. However, I don't really miss that particular aspect of my old car. It was fun with 450ish hp, but it was never enough even though it was way too much all at the same time. A non-boosted NSX is still a heck of a fun car, just not so much off the line.:wink:

Another option for you is to sell the SC and damaged engine. Purchase a decent stocker and you'd probably break close to even. With the money saved you could buy something else that has some torque.
Or if you really want to man up you could be the first to do the Gen2 swap.:smile:

Whatever you do best of luck and I still owe you a beer!

What does rrfmu stand for? Were you on the stock ecu and running a supercharger then without any piggy back?

Rising rate fuel management system. The boost a pump regulator that comes in the kit.

I was just about two months from going fic and high boost with an aftercooler too. Now I guess I will do all of that with a built motor for boost. At this point I cannot point to the reason yet, only decide the future of the x.

Thanks! The nsx is just far too slow for me in oem form. I was quite happy with low boost for two years without a thirst for more. I think 450hp is perfect for me in this car. I will most likely go low comp and 10 psi. I am too far into restoring the car to quit now!

Thanks! The built motor is something I wanted anyway. I drove the new car, didn't care for it like the old one. I'd rather sink 20k into my car than get something else.

Have Shad take you for a ride in one with a 2.3L compressor. That's not an expensive upgrade and if you're building the motor, it will turn your car into an animal. Pretty sure you can get it smogged with that too.

Thanks, yes I will be talking to him about that along with what tuning I can get away with here in CA. 1K2GO ran that set up. Supposedly Shad told him that it makes far less heat. He also is stocking his DA aftercoolers again after the laminova set up was discontinued. If I can go full stand alone with a cheat tune for smog, than I will definitely do that.

saansijack · 4 March 2017

If your goal is 450 to 550, you should be fine without decking. Anything over will be a time bomb(depends on your tune, as seen in catheys 650 NSX stock block that lasted him quite a while, he did have a very good tune). Get the HD rods and nice pistons. Stock crank should be fine as seen in auto waves build making more than 1k, while you at it, pp them heads. He'll, turbo it too!

So I spent the morning picking up the pieces so to speak. I pressure washed the motor and got the remaining oil off of the body. I wonder if there is an award for the cleanest blown motor nsx?:biggrin:

RYU · 5 March 2017

oiiiiiii, why am I just seeing this now. I'm sorry pal. That's such a bummer. If its any consolation, I think you're the only one in recent memory I can remember that's blown a motor on the stock CTSC setup. Not sure if that makes you feel better or worse.

FWIW, I was always wondering why many more didn't blow. My 1st year dyno'ing my NSX with the stock CTSC we started noticing subtle fuel mapping failure points in the dyno graph as intake air temps got hot (trust me.. it was wacky). That was a sign I needed to yank out the RRFPR et al and that's when I went with a HKS computer. ECUs are so so so underated. It's like the difference with your gradeschool calculator vs. a smart phone. The following year or so, I got lucky and noticed a weeping head gasket at the #5 cylinder, while R&R'ing the headers... I got lucky because it could have blew. The early cars are known for having a paperlike head gasket that doesn't like prolonged boost. It was at that point [MENTION=4034]Coz[/MENTION] came to the rescue and basically rebuilt the heads with a Cometic head gasket, LMAs, Toda oil pump gear and other bulletproofing materials. The last item needed was the water/meth spray system to keep the intake air temp consistent and predictable. Even though i'm only on 7-8 psi "low boost" my setup has been bulletproof for about 4yrs with several track miles. KNOCK ON WOOD

Speaking from experience after trolling nsxprime for 10+ yrs... you ought to stay <400wHP because other sh*t starts breaking like transmissions, motor mounts, axles, etc. It's a f*cking waterfall of hurt dude. I'd recommend going 400whp (maybe 425wHP boost by gear) and getting a 4.23 final drive for the acceleration bonus. Yea, there's a passionate group of owners that will swear their 600+wHP haven't broken this or haven't broken that but this is my take having known several guys here in SoCal that drive their cars hard that don't spend time online.

I'd also recommend you look at the turbo kit [MENTION=20830]A.S. Motorsport[/MENTION] is offering. It's one of the best thought out turbo systems out there. The SOS twin is also nice.

Lastly, much respect to Shad but I would never put that aftercooler on my car (see my build thread why). If you must stick with a CTSC setup, do what I did and spray meth/water instead. It's cheaper and distributes the cooling more effectively. It's add insurance by way of added octane from the meth too.

Good luck amigo. You'll get out of this better at the other end!

Thats some elite advice right there.........

Stephen@NCAutoUSA · 5 March 2017

I actually never knew you could get away with being supercharged and only have it regulated by the fuel pressure if I'm understanding correctly. I even say fic isn't great and lacks a lot of things but I guess each their own. I'm not up on Cali law but I would say get a good engine management system and monitor things like you've been doing. Know what types of pressures your car is and although sometimes things go boom quick there are situations and warning signs that something is wearing.

RUNDLC · 6 March 2017

Jinks,
NOOOOOOOOOOOOOOO!! Ah man that stinks.

Yeah, I am kicking myself in the ass for not yet upgrading to at least an fic. But I am still unsure what caused the issue. Either way, the car will be built better now.

Jinks · 6 March 2017

[MENTION=20915]RYU[/MENTION], thanks for the advice. I know you swear by meth, but I know a few people running the DA intercooler up in the North with great results. Keep in mind, I am in Nor-Cal where it rarely gets above 80 degrees. But first things first, the car is going to DA for analysis. Then I will make my selections of how I want to take it. I want either 430 to 460 hp. Nothing more. Twin turbo or single is a no go for smog. Otherwise I would have already had one.:wink:

Quite a few pages in your thread, where am I looking in the thread, or could you elaborate? I do get the pros on the meth injection, just wondering what the down side on the DA cooler is or if you had issues. I was under the impression it was a lot better unit than the SOS setup was.

mochanges · 6 March 2017

Damn sorry to hear this happened.

comptonassdaniel · 7 March 2017

Damn brother. I was surfing other threads and came across this. Very sorry to hear. I want to boost in the future, but might have to get my engine in order prior to doing so. Keep us posted!

Thanks. The engine will be built wildly now. Can't turbocharge but will build a wild ctsc set up.

Very nice! Will you be documenting the build? Interested in seeing what goes into it.

I will try to. It will depend on Shads willingness to keep me updated with build pics. Car won't be going to him for a couple weeks though.

8KC30A · 9 March 2017

Sorry to hear about the engine Jinks. Looking forward to your epic engine build thread.

What happened to IK2GO's car? I had been following his build thread, but the updates dried up about a year ago...

socalx · 9 March 2017

I'll go against the grain here and go on record as suggesting to buy a used c30 or c32 engine and either stay stock or go (or stay if the lysholm is okay) with low boast comptech. (Lysholm or Kenny bell billet). All the other advise just doesn't make any economic sense. I've thought about every scenario over 3 nsx and 15 others years of ownership. But regardless of what you decide I enjoy your enthusiasm and will be readjng and enjoying where this goes from here

So, this just happened.....
