So I’m trying to determine if I’m gonna need bigger injectors than the rc 550’s that I currently have. I’m stock b16, gonna be on 12-13 psi, on e85, with a walbro 255, stock fpr. I think 550 would be enough on pump gas, but on e85 I’m not sure. Right now on my na tune, at 8200 rpm the injector duty cycle is at 60%. Add 13 psi onto that and I don’t know if that’s gonna be enough. I just wanna try and figure this out before I get everything done, tow my car out of town to get tuned and then find out on the dyno I’m gonna have to get bigger injectors.
Those injectors arent enough, im 400 whp on 14 lbs e 85.
My 750cc are maxxed out at this point.

=[ Wanna trade for some 550s? lol. I guess 750’s would be enough for my power goal, but fuck it. I might as well get 1000’s and call it a day. Wonder how much I can sell my 550’s for.
Got my new pet snail today!!! It’s name is Gary >=] It’s a Garrett t3 50 trim .63 ar hotside with agp housings. I can’t wait to get this thing on my car! =] I love it
Some people fill up their shelves with books, magazines, or movies. I prefer to fill mine up with turbo parts >=]
Nice setup and turbo choice! Should have great response and spool time with that. .63 should be good on the B16 in the higher RPMs.
Thanks. Oh yea, it should be great. Picked this turbo for several reasons, but the main one was with my pressure ratio and psi i’ll be right in the center of the 78% island of the compressor map, which means this turbo will be very efficient on my set up. Not only that, but I’ve got room to increase the psi in the future if I want and still be in that same efficiency island.
I’m gonna wait till it gets cooler before I start putting all this one for test fitting. This is Texas, so hopefully middle of October it’ll start to cool down and become less humid. I’ll continue to post photos as things happen
Got the catch can installed
These are the last shots of it as an n/a car. It’s been a fun n/a car…slow, but fun. I’m gonna start putting the turbo stuff on now and it’s gonna sit until it’s all complete =[ I’m excited for what it’s gonna be in the end, but i’m sad it’s just gonna sit for a couple months. I hate when I’m not able to drive my cars. I figure though if I do this it keeps anything bad from happening to it (knock on wood). If it’s sitting I know it’s safe and healthy.
best of luck to you sir!
Thanks
Very nice, I’m looking forward to seeing how you make out. I think this is a great setup as well!
Thanks. For a relatively cheap and basic setup I think it’s gonna be good. I have a vision in my head of how I want it to look when it’s all done, but unfortunately I have to wait until it’s all done to see if it really comes out as nice as I envision it. We’ll see
Anyway I got bored today and test fitted Gary to see how it would look on the manifold. What amazes me is how fast cast iron gets rust on it. All this has been sitting in my room since I got it and somehow with having the windows open it aloud it to rust =[ I’ve gotta get it all ceramic coated as soon as I can!
Looks good. Yeah, I got my housing coating and did everything in SS. Can’t stand the rust on there. Do you have a specific plan with the exhaust and DP? Looks to me like the housing is on the wrong side as far as utilizing the groove in the oil pan. It makes things a lot easier on DA’s since the exhausts already sit low.
My plan is get a downpipe made that will connect to my exhaust. There are plenty of performance shops around here that can get it done for me. Some people will say I need to get a full 3 in exhaust when boosting, but I refuse to get rid of my rsr. Even though it’s only 2.25 or 2.5 whatever it is I love the way it sounds and it’s the full stainless version which is rare. Now the wastegate dumptube is not going to be routed back into the exhaust. I love the way it sounds when a wastegate opens and just dumps
Gotcha. I guess my question relates specifically to how the down pipe will come around from the transmission side and back under the oil pan. It’s been done plenty of times but it might make things easier to mount the housing and compressor in the opposite direction than in your photo. You should simply be able to flip the housing on the manifold if you choose to do that. I ran my setup with a 2.5" exhaust and it really was a night and day difference from what I have now (3"). Turbo really needs a minimum of 3" but I totally get why you want to keep the RSR, very cool item. With the 2.5" there was so much back pressure on my motor. I would recommend a recirc for the dump tube, do some research and you will prob change your mind…the loudness will get old quick. Personally, I think it’s kinda ricey. If you do go that route at a minimum the dump tube has to go at least to the oil pan, otherwise you will actually be loosing power as the gases get sucked back into the motor. Great work so far though. Bay is clean!
i think with your set up and hp goal 2.5 should be enough.
Thanks for the compliment. I’m proud of how my bay came out compared to how it used to look (here is how it looked when I first bought it ImageShack - img0139vj.jpg ). I’ll see what happens when I go to test fit it on the car. Not sure which way it’ll be mounted yet. As for the dumptube, I want it dumped and I know that 100% lol. Might be “ricer” or not as classy, but I’m around 500-1200 hp cars every weekend when I film for Thirdhonk.com and I’ve grown to love hearing the wastegates open up and just start screaming. I’m not just gonna stick a simple pipe on there and call it a day though. I’ll make the tube go down below the motor and slant back with a bologna cut so the air passing under the car acts as suction and pulls the gases out. I know a little bit about physics and I know if I put a tube straight down at the ground that air under the car will act as a barrier and wont allow the wastegate gases to pass out nearly as well.
Yea for 250-300 it should be fine. If not, then I’ll get an electronic cutout put in. I love exhaust too much to get rid of it for a bit more power
So no update yet =[ I had planned on raising the car up this passed week and getting to work test fitting and making my hotside piping. Unfortunately, mother nature decided I should wait a week until it stopped pissing on my parade lol. The rain here has finally stopped and the temperatures and humidity have finally dropped =] So this weekend I will start putting things on. I’m still waiting on my boost gauge, it was shipped but idk where it’s at. I’m still trying to find someone in town who can ceramic coat my stuff for me. Anyway I’ll post back as things get done, thanks for the support everyone
So small update
I got my car up on jackstands today, drained the last of the gas out of the tank, and test fitted the manifold and wastegate
This is how she will sit till it’s all done =[
The wastegat just barely clears the head. It touches the head, but just a tiny bit. It’s not pressing into it though
I’m gonna have to either get a slim fan or mount that fan on the opposite side of the radiator if it’ll fit. Not sure yet until I test fit the turbo later this week
Ugh so bummed right now. Went to test fit the turbo and it wont work with the manifold I have =[ It wont mount one way cause there is no room for the dp cause of the radiator, and it wont mount the other way cause it hits the block and wont allow the manifold to sit flush on the head
This is the way I wanted to mount it, but look how close the hot side is to the radiator. There is no room for the dp even with the fan off because the turbo sits at a weird angle.
See, no way a dp would fit cause the radiator not cause of the fan
Inlet part hits the block and wont allow the manifold to sit flush. I’ve already shaved as much off the block as I can
I see two feasible option here.
#1) I can keep this manifold, buy a 1/4in steel flange and use it as a specer, and get some extended manifold studs. Or #2) I can sell this manifold, sell my injectors which I’ve been trying to do anyway, and have just about enough money for this manifold (http://www.go-autoworks-store.com/goautoworks-log-manifold.html) which will fix my problem. I don’t really want a spacer and 2 gaskets on there. I don’t want it to look janky and half assed, but that option is cheaper
Damn man, of all the things that could happen…
What about tucking the radiator under the radiator support? I suppose it’s not likely that it will fit because it’s not designed as a “tucked” rad… Fuh…
