Highest Powered CA18??

[float_6969]

The best I've seen was 28 miles to the gallon. That was with my laggier, non-BB, modified T25, as oppossed to my current T28. That was on the highway, and still seeing boost. With the new turbo, the best I've seen is 27. The quicker spooling tubo makes it very hard to stay out of boost going up big hills on the highway, wich kills mileage. I think if I had a big T04R turbo on my CA, I think that I could pull off 30 mpg as well. This car gets great mileage off boost. Even getting on it alot, the worst I've seen is 17 mpg.

I'm gonna have to believe teambuiltnissan on this one.

Hmmm,

Twenty something mpg is nothing to sneeze at when you're talking about a performance motor. I guess if you guys say you are getting these miles per gallon with your vehicles, then perhaps you are. I just find it to be almost impossible to get such a huge injector to squirt such a small amount of fuel without risking the car to run too lean somewhere along the way or have driveability issues. I stand by my opinion on this and teambuilt, I hope you didn't take offense by making the comment "but I don't see anyone here doing as well as we do" because no one here is trying to out-do you or your gang. And it wasn't an attempt to make you shut-up as you put it, but if that's what you chose to do, then that's your perogative.

Congratulations on extracting 489whp from the CA! The guys here needed that boost in confidence and you and your crew provided the video of a good running car. And though there is no video of a dyno, I truly believe that you guys own such a beast.

well 489 is just a base pull.. I added intake manifold, 80mm throttle body, 1600cc injectors, new garett t04r BB should be interesting to see ... I just dont have a time to do anything since I am organizing the contaier from back home (japan) plus got 8 cars as up yesterday that I will be working this week..

whenever I find the time I will see the the number that I would like to see with VP import on 30psi+.

I am also working to find out how well will stock sr20 ecu will work with 1600cc injectos.. those for rom tuning.

dee. I am just trying to help other but I can careless what other poeple say if they dont listen. thta is not my problem. and also its not a problem for me to shut up . and I dont think I ever say anything about wrong about what I do and what I have showed. eveyrthing is shows my work and proof is car is runing like first day after 1.5 years and over 10000 hard miles.

I tunes and builts car for living and garage paddy is working with me to fill in insight of CA engine.

that is something that you dont have but I know that you know about ca engine than anyone else in US.. but that does not mean you can call BS on alot of thing that you dont agree with. but again I am trying to give you guys little of insight of what I do and what we do so rest of sr20 community dont give a crap on ca.. ca or sr.. both engine are great.. its just different.

matter in fact paddy is coming to my work sometimes this month. we have little bussiness to disscuss. we will have alot of dyno time at my shop. BTW. dee I emailed you..

Hey man, I only used the B.S. icon on the miles per gallon issue, not your tuning abilities or anything else. I do realize that I may have been a bit premature to raise the B.S. flag as I am doing my best to attempt to validate you high mpg claim on a high performance motor. If I can get anywhere near 28mpg (like say 25mpg), I will personally apologize to you in front of all other members, remove the BS flag icon and edit my original post.

If I drive my car normally, I may get as little as 13mpg (city) and maybe 17-18mpg (hwy). As of now, I'm driving the car like a straight-up bytch only gunning it to get out of the far lane just to get off on an exit and this driving may very well yield 20+mpg. But with a car like what you have and a car like I have with my car being the lighter of the two, there is no way sanely possible for you not to enjoy it and be mileage conscious.

So do any of you agree that, if you do not romp on the pedal, keep speeds under 70mph and keep vacuum below -10hg by keeping that throttle plate closed as much as possible, it will yield decent mile per gallon, but at the same time possibly defeat the purpose of owning a turbocharged car? I'll get back to you guys when my tank runs low and teambuilt, I'll check my mail in a minute.

Keep up the good work and keep the group informed with your collaboration with garage paddy; that ought to be interesting as well. Hopefully within the next month, I can get a few cars I worked-on including my own to a dyno to see if they can break the 500whp barrier. I believe they can, but we won't jump the gun as of yet.

I do agree with your that having a high performance motor and worrying about gass milage doesn't go hand in hand

On the ONE time I have taken it very easy with the fun peddle I have got over 30 mpg, mostly I'm lucky to get into double figures lol

[float_6969]

Oh yea, I never said that the car was fun to drive to make it get that kind of mileage, but it can still do it. I also have the car set up so that the limits to enter and exit closed loop are very broad, so it's often running near 14.7AFR. That in combination with the rear end and KA-E transmission I think has something to do with my mileage. I'm not sure what effect the 48:11 rear end and the CA transmission 5th gear will have on the mileage, but I should know what the diff will do by the end of next week as I plan to have the 48:11 + Helical on in the next couple of days.

Quote »full boost by 5600... power band 5600-9000. is not bad.to be honest. its very streetable. only way to know if it is streetable or not is to own one.. if not you will never know.. this is 1.8l small engine.. if this was my old lexus then yes it is pretty useless til 4th but that is 6cy

I did 1.41 60ft with my old turbo and intercooler popped off.. but with this new BB turbo.. boost transition is great and be very pleased.

I only spins on 1-2nd on street tires 245 50 16.. good traction on 3rd.. [/quote]

wow thats pretty sick, i am running the same tires now (245 50 16 nittos) and i only loose traction in 1st & 2nd, small chirp in thrid.. i am making about 300rwhp.

you quickly learn when to step on it when the rear end can kick out under hard acceleration on the street, and laggy turbos help you behave.

i would also beleive the MPG situation, once i stay outta boost i get real good mpg, once i step on it i can literally see my gas gauge going down once under 1/3 tank. i just dont get the opportunity to give it gas during the day with all the traffic so my gas milage is great for my daily commute during the week..

c'mon man, show us some vids, pics and dynos..

[CA19DET]

and a couple more things, why two wastegates and what kind of turbo manifold is that??

also where did you get the plenum for the intake manifold??

thanks

[teambuiltnissan]

one 38mm is not a enough .. boost creep. I have tried 60mm wastegate.. dont work on CA.. too big. same as 50mm.you need to be able to figure and keep the adequate amount og backpressure. 60mm valve is way too big.. when it opens it drop the backpressure bunch.. tested with gauge to be sure on pressure.

intake manifold is one off made..I made most of it. I just bought outside of intake housing and volacity stacks, put together.

you can get most of parts from http://www.rossmachine.com

[CA19DET]

thanks

and is it a HKS T04R or a Garrett T04R/T3 hybrid?

and why not a GT3040 or GT3037R or GT3076Ror even a BB T04E ??

just cutious what made you choose that turbo, in know its good for 1000hp with teh right turbine and trim, was wondering if you could have made the same power, with a smaller turbo, with better spool but more boost (i guess running more boost will lead to boost creep and hotter intake temps, more fuel etc)

also what turbo manifold is that and can we have a better looka t it (photos from different angles)

PS - i would also like to PM you about my engine and tuning set up etc.. i am about to put in my forged engine and would like some pointers.

and once again really impresive

[Kouks]

Yes i would love to hear what you have to say. We ( as a community) could greatly benefit from that kind of information.
