Turboing a D16

[mattcivic]

In the June 2003 issue of SCC mag they have a section on Turbos (page 174 to be exact). They have all kinds of turbos for just about any kind of import car, and some domestics. They have a Turbonetics kit listed for the 92-01 D16 motor. I'll list all the particulars in case people don't have access to the mag. Turbo Turbonetics T3/4 Hybrid - T3/T4B V / Stg II .48 A/R Wastegate External - Turbonetics Mark IV wastegate; High nickel cast steel manifold Blow off valve Turbonetics Raptor Bypass; Spearco front mount intercooler; additional injectors, additional injector control and ignition control. Boost: 8 Psi; Now heres where it gets interesting. The claimed Horsepower at the wheels is 225 HP (dynapack dyno). Is this possible? Thats like a 100HP increase over the factory Flywheel HP! Not to mention its like over 125 HP difference at the wheels over stock. Is this possible with leaving the internals stock?? Everyone always says not have the boost level over 7 or 8 psi on stock internals. So will this work?? Somebody with knowledge of turbos please give me some input. I guess I should stick with the old addage, If it sounds to good to be true...it probably aint true I would love it if it wasnt though. The price listed for the kit is $3,799. Let me know what you think

that claim is on an EX motor which has 127 stock. yes it is possible with the correct tuning. if you just strap on the turbo and run it .... not a chance of 100hp. most turbo kits run 6.5-8psi with an FMU and thats about it. well the FMU is a good fuel system to give you enough fuel not to blow the motor. but if you are looking to get some major hp, you're going to have to go with an electronic fuel management system such as Zdyne, AEM, Hondata, etc.. these systems control bigger injectors which allow you to safely put more fuel into the chamber without raising the fuel pressure from stock (or using a high flow pump). It also controls the injectors very precisely. the more acurate the control is the more power you are going to be able to gain. the system you talked about included electronics such as this and an ignition system to retard the spark. that means that this system is easily upgradable. I would say that this system is not scamming you with the hp increase that you will gain. but it's torque that you want to gain. horsepower is nothing without torque. you will probably only gain 20-50 ft-lbs of torque which is a noticable increase. for almost $4g, I don't know if I'd be all about that kit though.

I would be upgrading the fuel system as well, with Walpro 255 lph pump, Aem fuel filter, pressure regulator, fuel rail. So I should be looking for the kit that raises both Hp and Torque? I was looking at the Fmax kit which claims only 155 Hp but 205 ft/lbs of Torque at 4000 RPM, and produces this all the way to redline. The only problem with that is that it is done at 15 psi of boost. They say that it has been driven around as a daily driver for 7 months with no problems, however they did change the head gasket. I am inserting the link to the page so you can read about it.

Let me know what you think of this one.

I would jus do a GSR swap...Probably about the same price MAYBE cheaper with a lot more bang for the buck

[mattcivic]

From the looks of things, it sounds to me that it wouldn't be that much of a difference by putting the F-max turbo kit on my D16, over the GSR swap. 155 Hp and 205 ft/lbs isn't to far off from the 170 Hp of the GSR and the torque numbers are way better. Not to mention that the GSR torque #'s of 128 ft/lbs doesn't come until 6200 rpm, and the F-max turbo kit hits 205 ft/lbs from 4000 rpm all the way until redline. If you click on the link that I included in my other post on this topic and than click on the Dyno sheet from the turbo, you'll see that at redline the D16 is pushing 200 Hp. The reason I say redline is because the d16 redlines about the same time the GSR hits it's HP peak at 7600 rpm. So overall I am fairly confident that this turbo kit would beat a GSR swap, and if it's for the same amount of money???? I'll take the turbo over the swap. I guess I should have expected someone to throw the swap option in there, since everyone is all about swap swap swap nowadays. But just look at the numbers, the GSR will NOT give me more bang for the buck.

Check out www.turbod16.com . That has alot of good information for turboing a D16 motor.

First of all, its true that you don't want to run anything over 7 or 8 psi on stock internals. I don't even recommend bolting on a turbo kit unless you upgrade your pistons, rings and all the other things really necessary that everyone forgets about for running a turbo kit. A 125hp boost on the d16 motor is a lot. That is the most I've ever heard. On any turbo kit at that in d16 sohc engine. My guess is that they are trying to sell you a product. One thing what they could have done is put on a larger than normal size turbo in the kit. It would deliver more power but it would take forever for that turbo to spool up and deliver that 125hp increase. And with an oversized turbo on such a smaller engine, you would have to also run at least a 75 shot of nos so you can help that turbo spool up faster. My recommendation is to upgrade the internals of your car and than ask a professional in your area about what would be the best thing to do in your case for a turbo upgrade.

I am currently building a custom homemade turbo kit for my D16Y7, and i am plannin on runnin high 13's low 14's with it on stock internals except for some LS rods, I am building the turbo kit with a 14B turbo, with custom 5 inch intercooler. I plan on runnin 6psi daily driver, and about 9 psi at the track. But here is the kicker this turbo setup i am plannin which i have most of the parts for already, is only gonna cost about 900 dollars, so compared to a swap its worth the money.

I can give you a complete parts write up if you want me to.
