Hi this is my build list and motor should be ready this weekend. I'm looking for opinion from those who have or had turbo d16. i have access to a garrett t3/t4 .50 a/r, or ebay specials i have lying around currently used for paper weights! I want to make sure I have enough turbo so I don't waste my 800 on tuning! ebays are a gt35 replica .70ar and a genaric t3/t4 says .63 on exhaust side. But will the garret provide enough flow? rather use the good stuff! 300lb tq I would like or 400-450whp what ever it works out to be. any help is good thanks in advance.

May I ask what kind of use will this car see most? And what is your budget?

You will save a ton of coin and have the same, if not more control if you go with Megasquirt stand alone ems. However, if you don't have much experience with ecu's/tuning, maybe you're better off going with a chipped obd1, Ectune and having someone else tune it. Just seem like a shame to spend so much on something you can learn to do yourself.

Anyways, make sure that cam is for forced induction and not NA. Otherwise it will hold it back and reduce the potential power due to excessive overlap in the timing. You should also get an adjustable cam gear.

Also, don't choose an amount of boost. You already have a power goal and that is what is important. The amount of boost required to make that power on this application will be determined by the turbo you use, how well the engine is tuned and a few other factors based on the components of the setup.

Also, I don't recommend you weld the diff.

I just want power to go fast 10 seconds or less. I looked at Megasquirt stand alone ems and looks cool but I would have no idea how to tune my car, I would be scared to blow it up! I have an adjustable cam gear to go with the cam and the cam is meant for boost.

I have been looking at hx35 turbos and GT3076r turbo. any feed back on them ?

K-Tuned

I tune lots of Megasquirts on Mazda Miata's and I would never recommend one for a Honda. You would be best to get a Neptune Tune in a chipped P28/P06 ecu. We normally charge about $600 for a Turbo tune and that includes the neptune license.

Megasquirt is excellent.. (I have one on my Mazda, but my Acura with a K series runs a Hondata since I find nothing does it as well as a stock based ecu)

Just my 2 cents...

D.T.P

^^How so? Would you care to elaborate. Just wondering really...

Also, OP if you can get an HX35 cheap, its a great turbo and doesnt cost an arm and a leg. If i recall correctly, brand new they can be had for around 800-900$ (or maybe that was my price...not sure)

Moreover, make sure its NOT internally gated. The stock boost setting, depending on the model, stock boost can be as high as 18psi...

Megasquirt is a great system but you have such easy and wonderful solutions for Hondas using Honda ECUs. No point messing with a megasquirt when you have easy solutions which work.

MPR

^There is no "messing". My MS setup on my b16a2 is basically plug and play with very little "messing".

There are many ems solutions for hondas. MS is one of them. I happen to be familiar with it and that's why I chose to go with Megasquirt. Its a lot less expansive as well for an extremely capable full stand alone system where the tuning software is 100% free.

My whole setup has cost me $450 and I'm nearly ready to tune. And I don't have to take anywhere and have someone else tuned it.

But like I said, there are tons of options for tuning hondas. If you don't know how to tune it yourself, then neptune is probably the next best option.

K-Tuned

I'm very comfortable with Megasquirt I & II and use Tunerstudio to tune all my customer cars. As someone who uses both MS and Neptune I can honestly tell you that Neptune is better for a Turbo Honda.

Plus when I charge $600 for a Neptune License, Dyno and Tuning it is a damn good deal. You purchase a Megasquirt you still need a dyno to maximize your power, and maybe a tuner if the customer can't do it themselves.

I'd be more than happy to tune a Megasquirt Honda, but when I have to advise someone I advise either Hondata (Lotsa $$$) or Neptune (Little $)

MPR

^I agree $600 is a good package deal for someone getting it done by someone else. And the neptune setup is definitely more convenient and easier since you're using honda oem ecu components.

As for the hard-core DIY'er and TIY'er (tune it yourselfer... :P) Megasquirt is a lot less coin for the same or higher level of tune-ability. MSII is $250 and a decent wide band is about $200 (innovate MTX-L), that's $450 and ready to go. I just have to fabricate the wiring harness for it that will plug in to the factory wire harness. This will allow me to switch back to the stock ecu at any time. So there's no butchering of the stock harness.

As for tuning, we have only ever tuned our MR2 on the street using 3rd gear pulls (on the same stretch of road, which btw is out in the middle of nowhere) and a person in the passenger seat with a lap top and a calculator with the data logs to determine approximate output (yeah, we're nerds...lol). When we did dyno tune once with the supercharger, we found we had pretty much already maxed out it's full potential. There was very little left to gain. Also we weren't too concerned with peak output but rather a wider, more useful power band (for autocross).

Anyways, yeah neptune is great and a good price for those non-DIY'ers, for sure. I just enjoy doing everything myself and would rather save a couple hundred dollars, have fun learning and building the MS and the ability to tune it anytime, anywhere.

To each his/her own.

Any thoughts on eCTune? I wouldn't mind learning how to tune as i could help friends out. I have access to a dyno from a friend.

I think I am going with a t3/t4 .60 trim stage 3 wheel .84ar I can get mine built like that for 600. Good deal? any turbo re builders you recommend? that was from cherry turbo. thanks for the input

You're going to have to look at compressor maps of different turbo, plot your engine and hp air flow on the maps and see which one will work best.

If you don't know how to do this, there are lots of web sites that can help walk you through it.
