If I remeber correctly the GA16DE engine does that too. Those guys splice the lines together and bypass the TB. You would have colder air going in the engine. Just don't do it in the winter because the throttle can freeze

Hi Guys, I have been following this thread with interest, and I thought I would tie up a few loose ends. I hope you don't mind. There are no injector upgrades for an Electro-Injection [or TBI] unit. You can't put a GA16DE injection intake manifold on a GA16i [and certainly not an E16]. The GA16i head has no injector tip cutouts, for the direct port GA16DE intake, and the center studs are spaced differently. As for finding a twin side draft intake for an E16, they exist [I have one on my B11], but they were discontinued many years ago, and are very rare today. They do make great power, but it is all at high rpm, and really not the hot setup for a street car. They have very little low rpm power or torque. I agree with Ricebox's quote: [This sounds pesimistic but I don't suggest trying to mod the e-series engines past intake and exhaust or maybe a "euro" cam. It has been done before, but the engine was just not designed for big power, and all the work is not really worth it]. The reason I agree with him is because I have found that unless you basically build it as a race engine [raise the compression, get the twin carbs, header, cam, etc.] it won't have the power you all are looking for. And when you build it as a race engine [like I did, read about it at: http://www.b15sentra.net/forums/show...Rebello+Racing], it makes no sense to try to run it on the street, because you always need high octane race fuel for it. There is one exception: an E15T. If done right, you can make good streetable power with a turbo E15. Bottom line is, if you want to make good power and still buy cheap gas, you need an SR20DE. I hope I haven't offended anyone here. I have spent many years developing my E-engine combinations, and am still a fan of the mighty E16, but it does have its limitations.

do you have some hp to give us on your all-race e16 engine you got ... have it been dinoed ??...

just to see the possible N/A possibilities here...

Hi Marty, no I don't have any dyno readings, but I'm sure there is a formula to determine it. The important specs. you'd need are what the car weighs and how many mph in the quarter mile it ran. We have both of those specs. My B11 is stripped of all unecessary weight, and weighs 1680 lbs [but you must add my weight{170 lbs.} to that for true race weight]. The car went 96.9 mph in the 1/4 mile. Anyone got a program or power/speed calculator to figure this out? My guess is, that at the crank she makes about 150 hp. [more than twice the stock figure].

Crazy-Mart · Aug 31st, 2002, 11:59 AM

well it is very good... you got some ass kicker out of that e16 engine there... sur would be better if it wasnt that bad on pinging... but you could probably get about 115 hp at the flywheel without that many mod and probably less pinging too... could kick ass too !!

Crazy-Mart · Aug 31st, 2002, 12:01 PM

forgot,,, wath time slip did you make on the track with it...

96.9mph... and need to know final gear ratio if not the original tranny... or if you bought the nismo FG...
the program i had calculated it with the ratio to...

blownb310 · Aug 31st, 2002, 03:24 PM

Thanks Marty, The ET was a 14.18. The final drive gears were 4.16's. The transmission was a rare Nissan Motorsport Option #2 Ultra-close ratio 5 speed gearset. Those ratios are outstanding for a high revving E16's. I also have the option #1 Middle-close ratio set too, and it improves accelleration alot over the stock RS5F30A box. But unfortunately, [and I was warned about this when I bought these gearsets], I blew up both of these ex$pensive gearsets. One broke 2nd gear and the other broke 3rd gear. Just sheared the teeth completely off of the cluster gears. I bought these sets from road racers in CA, and they said the reason I couldn't get any replacement parts to fix them, was because THEY blew them all up! Oh, by the way, I've got to tell you guys, that my 150 hp E16 is SLOW compared to the E16's that Rebello Racing builds in CA. He's got normally aspirated [twin Mikunis] versions with dry sump lubrcation, billet crankshafts, custom steel rods, ported turbo heads with oversize custom valves, etc, that make 225hp! That was 10 years ago. Who knows what they're making now? The reason they sold me their Motorsport gearboxes, was because they were totally inadequate for their race E16's. They use some aftermarket dog engagement racing transmissions, with straight cut teeth. Which brings up a good question for Hybrid DET [when Charles ran the E15ET] and Ryco: How have gearboxes been lasting for you guys?

Crazy-Mart · Sep 1st, 2002, 12:12 PM

on a test ive found on internet it give me the falowing
wich i think is at the wheels...

128-130 hp...

Crazy-Mart · Sep 1st, 2002, 12:16 PM

well ive founded another who give me those:

155hp at flywheel and 130 at wheel assuming 18% drivetrain loss

wich i think is probably good...

blownb310 · Sep 1st, 2002, 09:13 PM

Very interesting Marty. Can you list the websites that you saw those figures on? I'd like to read what engine pieces were used in those tests. Thanks.

Crazy-Mart · Sep 3rd, 2002, 08:15 AM

well im gonna refound those and list them here tonight....

On one of the threads recently, someone was throwing some ideas around, and wondered if they could increase the power of an E16i, by using the throttle body injection from the GA16i. I didn't give it much thought, because they look basically the same, and I consider both to be pretty useless for high performance applications anyway. Then it ocurred to me tonight, that the GA16i makes 20 more hp than the E16i. I suspected that this couldn't be done, with the same size TBI. I have both of them here, and I removed them for a closer inspection. My hunch was right. The E16i has a smaller 38mm throttle valve. The GA16i has a much bigger 46mm throttle valve. Here's the good news: the bolt patterns are identicle. It'll bolt right on. You'll have to open up the small 38mm hole in the E16i's intake manifold of course. There are some definate differences however. The E16i uses an AAC [auxiliary air control] valve to control the idle speeds. The GA16i uses coolant to expand a wax packing, that pushes on some linkage to control cold fast idle. The size of the little coolant elbow hoses are different too. These things can be gotten around. The airmass meters, are physically the same, but not electronically. That's fine, just swap the original E16i airmass meter into the Ga's TBI. I have not personally done this swap [I don't think ANYONE has], but I think it can be done, if you've got the inspiration to do it. At least there may be some hope to make an E16i perform better on the cheap!

Crazy-Mart · Sep 4th, 2002, 12:02 AM

well thats great, when im gonna get to my junkyard im gonna buy one and try it out !!

Now you talk about a cheap mod!

very nice Blownb310, you got wath i originally looking for !!

Thanks alot !!

RiceBox · Sep 4th, 2002, 10:02 PM

I too want to see how this works out.

mustang302 · Sep 10th, 2002, 06:25 AM

When i get a second car i'll try it out.
But i was thinking of swapping in a ga16de enginr what do you think.
What would i gain by doing this and which injector do i use
