Hello community;
I have been reading from alot of posters about the heat issue w/a 14b turbo, and that they are too hot running and that they can damage your engine because they are too small etc...
ON the contrary, people have been reliably modding their DSM's with this upgrade for a long time. The turbo flows 405 cfm, and has a td05 housing(Same as a 16g) and is a much better turbo then the t25 that 2g's came with, or adversely the 13b that the autos came with.
So I suppose I dont understand where you guys think this turbo sucks for the 2.2 liter accord. Ive asked, but not really gotten any solid responses. The compressor mapping for the turbo ligns up great with the motors natural CFM's, and I haven't been hearing the right kind of complaints about the turbo to think its the turbo thats giving you guys the problem. If the turbo was too small for the engine, it wouldn't hold boost through your pull. It would drop boost at a higher RPM and build boost almost instantly. Similar to the T-25 on a 2g DSM. It runs out of turbo in stock form, boost drops or starts dropping around 6000RPM. So I guess what Im getting at, is maybe theres some miss information going around here.
I have been a DSM guy for 10+ years, but am doing a CB currently for a fun DD. As Ive been learning about these cars, this was something that Im just baffled by. The 14b is a great turbo. I have as well as many others have had great luck w/a 14b.
I think that whats going on here is too many people on this forum think you dont need to run the coolant lines on the 14b, thus creating a heater in your engine, and creating the heat soak issues Im reading you guys talk about. Think about it like this;
People run the 14b on 14-20psi, daily. Their DSM is a gas, combustion engine just the same. Most of us running a turbo on a CB have a front mount intercooler, as opposed to a side mount the DSM comes with. SO what do you guys suppose is the difference from the DSM crowd that runs a 14b all day long without any heat issues and have tons of miles of regular driving, where as people in this forum think the 14b could lead to catastrophe in an accord.
I think its worth pointing out that a turbo is just a compressor, thats it. So, its not going to perform that drastically different, over .2 liters of displacement or the tiny bit of extra compression. Nope, not at all. In fact, when you replace the stock pistons with aftermarket upgrades on a DSM they come 9/10 times in 8:8.1 compression, the same as a CB. So, all that leaves is the .2 liters of displacement, and the idea that nobody is COOLING their turbo.
Lets remember here, cooling turbo=getting rid of the heat. Not just running coolant to the turbo, the coolant then travels to the radiator remember, then the heat is removed from the coolant. If you dont REMOVE the heat, it has an opportunity to build up, gradually getting hotter.
The displacement difference comes from the length of the stroke, not the size of the bore. So, dwell times are different, but minimal at best. All that would do for you is sloww down the boost spooling, not over heat the turbo, and a little ignition tuning/timing would account for any differences in dwell times.
Plus, a CB only rev's to 6500 or so and the DSM rev's over 7200 sometimes up to 7500.
So, after scaveging all of my memory, using all of my knowledge, doing the math and comparing CFM's of the two motors I just dont understand why the hell so many people talk poorly about the 14b on this platform/forum. I honestly believe some of you just arent using it correctly.
Someone, please prove me wrong....
Theres enough SMART people on this site to show me some REAL SCIENCE that supports your guys' claims. I hate to think that all this hype is just a bunch of repeated miss-information.
