Putting a GA16DE in a B12 Sentra is not a simple process, though you get get great results. As for wiring from an E-series to a GA-series, I don't have a clue in all honesty. I've never worked with E-series wiring, though I imagine you could probably cut and splice the harness if you needed to. It might be easier to go straight MegaSquirt stand-alone ECU. Most of us GA16DE-swappers have gone from a GA16i to GA16DE.

P.S. I don't have AIM anymore, but I do have Yahoo! Instant Messenger. My screen name is "cairnaec". Just hit me up sometime when I'm on.

Well, man, I talked to blownb310 and have pretty much come to the conclusion that I am not gonna do this sentra. I might yet, but chances are if I do i would just fix the E16, cope with it for a bit, and plan on the swap later on. For a motor I have never driven, I am pretty hooked on the GA16DE.. its a beautiful little motor, and I look at it as an ultimate incarnation of the old OHV 1600 from the mid 60s fairlady roadsters... which (along with the 2000 OHC U20 motors) my uncle races.

I looked at a 93 maxxima the other day that (if he hasn't sold it) I might pick up, and tonight while making a delivery I found an Isuzu Impulse for 700 bones. My first car was a 12 valve Geo Storm, and the Isuzu is like the bigger, meaner cousin of that car. Actually, the Isuzu has a bigger, meaner cousin as well.. and it is called the Lotus Elan. Isuzu built the motor, Lotus built the suspension, and Geo got nothing but a chassis and an 1800 that went into the GSi model. Sooooo.. I MIGHT abandon "the family" and go for the Isuzu, even though it IS an auto.. because the Maxima is too.

The sentra would need a head set, a timing set, and a few valves... PLUS a windshield, and its pretty ratty. It looks OK outside, but... I dunno, I will see.

Thanks for the help though! You helped me avoid jumping into a decision I probably would have regretted.. at least until I finished the work, heh.

Ah yes, Lotus, an amazing manufacturer I am quite experienced with. I've actually been to their manufacturing plant in Norfolk, England. Pretty cool beans, them. I find it hilarious that Toyota takes the same 1.8 litre engine in their Celica and produces 140 hp, and Lotus in the Elise produces 177 hp! We won't even get in the Exige. Anyway, the only problem I see with buying an Isuzu Impulse is parts. I know a guy down in Chattanooga with an Impulse, and finding parts is like pulling toenails. Painful. I've driven one with the Lotus-tuned suspension, and it handled like a dream, though. Just make sure you get the DOHC 1800cc engine, as opposed to the DOHC 1600cc one.

Actually, I have an Exedy clutch stage one. I actually got it cheaper than an OEM replacement one from CarQuest. For Christmas, I just purchased a JWT clutch and pressure plate. I had to splurge, so I went big. I don't remember off hand what stage it is, but I am sure it is better than stage one. Wes has been raving about them forever. Prior to the Exedy, I ran a Centreforce clutch and pressure plate. Didn't like the feel of it, though. Sorry about getting the timing for the car, but I'm currently overseas in the UK and can't exactly time my car in a different country. I'll be back in the US come Wednesday, so I should get it then for you.

Hey not sure if your aware of this but there is a tunable ecu for the GA16 although I haven't worked with it yet. There is a guy on SR20Forum who puts a daughterboard into a bunch of the sr20 guys ecu called Calum and he has an application for the GA(I'm 95% certain anyways he was working one a while ago I believe he got it working correctly) He is under the Vendor list on that site and they are fairly inexpensive as far as I can tell. I'm running the JWT ecu right now and have been very happy but for the fact you can't tune it... Just the JWT ecu on a basic tune dropped 1.3 secs off my 1/4 times. I like your build making me want to keep my GA over the SR...

Okay I officially suck at life(good thing I said 95% sure HAHA) I guess Calum is still working on the GA ecu but is planning on coming out with one still in R&D. Sorry about the misinformation.:confused:

Almost one year later now, any updates?

Biscuit, did you ever add an intercooler?

Mike

P.S. Just as you did, I lost one of my turbo to manifold bolts and blew the gasket between them. I replaced the low grade TSi hardware and added graded studs/bolts/ with red loctite.

I did add an intercooler (front-mount), but I haven't gotten a chance to drive or tune the car with it. I changed out the headgasket on my GA, and since then, the car hasn't run right. At first I thought a timing issue, and then the headgasket not sealing correctly. But, I've finally narrowed it down to the engine wiring harness. To put it bluntly... it is f*cked. Somehow it grounded out and fried itself. So, I am currently in the process of acquiring a '91 Sentra B13 GA that is going to be a daily driver. Once I get the B13, I'll rewire the B12 and get the beast back on the street. Once the B12 is fixed, the B13 will become a test platform... I plan on using the same setup as you are blown... SR20 ECU, MAF, and injectors.

GO Biscuit!!! You can put the daughterboard on the SR ecu :) Biscuit, you can use "fire ring" setup on the head with OEM gasket, I use this on SR+T builts and no issues at 25psi ;), (On SR 15+psi + no fire ring = blow gasket!)
