Ok guy's I have just begun to double in Japanese cars and I bought a 96 commuter car in a Sentra with a 1.6 engine. Well it has been a bit of trouble and I believe it to be somewhat worn at 200k. So with this in mind I went out and purchased a 46k engine and trans from a wrecked 96 and will be putting it in shortly for mpgs sake lol! Ok my question is I have two turbocharged vehicles in my stable as of now and Guy's if the little 1.6 is up to the task I surely would love to spank it with some boost pressure. I was wondering a few things though first who has done it and what hs to be done to get it done? I would rather not buy someones kit and if possible I would like to here from someone who has pieced it together? That is usually how I get it done but I am not sure about the engine management capabilities?? Is it up to the task? If i have to upgrade whats the best way to go? If this can't be done without costing a kings ransom I will end up passing. IMHO a small engine like this even boosted is only capable of a very low number? So if it can't be done relatively cheap I will keep the dough and put it into porting my Pontiac heads so the big engine can make more boost! Man this is a sickness for sure! Don't let anyone tell you it isn't! Lol!!

There are many of us on these forums with boosted GAs nowadays. I just finished mine the other night and finished tuning it last night. Mine is a pieced together kit; TSI turbo manifold, SR20DET T25 turbo, A'pexi S-AFC 2 (air flow converter), Walbro 255lph fuel pump, sequential blow-off valve, wideband (borrowed), and stock injectors (yes stock flow injectors that don't run lean at 8 lbs of boost!). Altogether, my cobbled kit cost me about $500; the most expensive piece was the downflow pipe from the turbo elbow to catalytic converter! eBay is great for finding steals.

I got lucky and got a lot of parts from a friend with plenty of left-overs from his personal turbo projects. If you've turbo'd plenty of cars, I am sure you have piping and couplers laying around that you can re-use or spare. There are other members who bought the entire TSI turbo kit (w/h T20 turbo) or the Hotshot kit previously made. So far the biggest turbo I've seen run on a GA16DET was a T3, but I know most guys run the T28.

Jim Wolf Technology makes a good deal of products for the GA16DET, including turbo cams, turbo-tuned ECUs, and all sorts of other miscellaneous things you might need (adjustable fuel pressure regulator, performance clutches, etc.). They seem a bit too pricey for me, though. That's why I opted with an S-AFC 2, which is very limited in terms of injector compensation (only +/- 50 in either direction). But, if you run low boost like me, and have good injectors (I am going to install 259cc ones later on in the week), you shouldn't have a problem at all.

Ya I have some stuff hanging around but I can honestly tell you that it is wayyyy bigger than I would ever think about using on a 1.6 Lol!! We are talking five inch pipe for the Cummins and four inch on the Poncho project which is still not complete. So is an engine with 46k still able to handle the turbo? What is your opinion on the auto box? Anyone have any idea on what needs to be done to beef it up? I think from experience that the auto will be quicker in the long run but it will also need to be built to deal with boost as my Diesel Truck trans was built!

My engine runs splendidly with the turbo on it. I am not one to push things, so I forsee my GA16DET lasting a long time as I will be sure to maintain it. I am also running only synthetic motor oil, and have thoroughly given my engine the once-over in regards to components to ensure long life. I changed the water pump about a month ago (in prep for the turbo), replaced all my coolant hoses, checked all my vacuum lines (the few I have), did a compression check on all cylinders, put in NGK V-power plugs (gapped for turbo and soon to be replaced with Iridiums), checked the front and rear main seals, changed my gear oil in transmission, welded tapped oil pan, NPT to BSPT adapter fitting, installed a Walbro 255lph fuel pump, put on a new Z32 300SX TT fuel filter, and just basically checked everything out.

In regards to the auto(tragic) transmission, I don't know how well it would handle boost. Low boost should be fine on it, but I wouldn't push it. Japanese car companies tend to make pretty poor automatic transmission since standards are their mainstay everywhere else in the world. I would do a filter kit change on it, and just make sure everything is in good working order. You might even want to install an transmission cooler in case things start to get a little hot.

Ya with out a doubt a nice big cooler on the trany will help for sure! I think I will try it and if it burns up then in goes the stick.
