Kam 1 Posted February 22, 2013 Share Posted February 22, 2013 Is there a turbo kit out for the Spark yet? Link to post Share on other sites
sparkplug 1 Posted February 22, 2013 Share Posted February 22, 2013 (edited) this is irrelevant to your question but it sure would be nice to have the extra power wouldn't it. it is hard going from 400 horsepower in my truck to 84 horsepower in the spark. it is a completely different mindset you have to get into Edited February 22, 2013 by sparkplug Smikster 1 Link to post Share on other sites
weetsj 39 Posted March 9, 2013 Share Posted March 9, 2013 torcon makes a turbo for the Spark Link to post Share on other sites
dbnspark 7 Posted March 26, 2013 Share Posted March 26, 2013 I've been wondering if one of these http://www.ststurbo.com/universal_turbo_systems would work. Link to post Share on other sites
Greg_E 211 Posted March 27, 2013 Share Posted March 27, 2013 You might be able to make it work, that hardest parts will be the exhaust header and the programming for the fuel computer. I've seen some universal kits that add and extra fuel supply like what you use with nitrous so that the extra computer keeps the mixture in the proper range and doesn't mess up the stock fueling. I'd also like to see an inter cooler, I know a lot of people are using water injection for cooling and knock control, so it might be an answer here too. Link to post Share on other sites
Lil Dew 14 Posted June 5, 2013 Share Posted June 5, 2013 It could be done. Get a GT1548 or a GT1241 for quick spool and around 120-150hp. Use a RRFPR for fueling, and set the timing back a few degrees. Turbocharging an NA engine is actually pretty easy. You just have to stay within the parameters of the stock ECU in this case. 5-6psi is about all the stock ECU can probably handle, fueling wise, even with the RRFPR. After that the stock injectors will probably get maxed out. The intercooler could be tricky on our cars because the intake area is high and rather small. There may be some room behind the fog light areas for a small intercooler. The hardest part is making the manifold and downpipe. You could cut the manifold pipes off at the flange, weld new pipes, and then weld on a T25 flange or better yet, a Vband. The downpipe is matter of fitment. Of course, our exhaust is probably 1.75 to 2 in, so it will be restrictive, but oh well. You could always do a custom 2.5 in exhaust to free up the system and help the turbo spool even faster. I built a turbo set up for my Mazda Miata from scratch. I used a T3, 60, Megasquirt standalone, and I made 247hp w/ 197 lbs tq at the wheels. It was a blast to drive. My wife was happy when I sold it, but my son was not. Emma Romero and ANewSpark 2 Link to post Share on other sites
malibuguy 14 Posted June 6, 2013 Share Posted June 6, 2013 Rising rate fuel pressure regulator. Wont work on a spark do to fuel on demand (returnless). Stock fuel pump should be able to handle higher fuel demand...its a matter of getting it to. I converted my tercel to a return style...was not too hard to do... Link to post Share on other sites
Greg_E 211 Posted June 6, 2013 Share Posted June 6, 2013 That means the bypass is in the tank like most other vehicles, just need to pull the pump and change to a higher pressure regulator and hope the car permanently learns the new injector times to match it. Link to post Share on other sites
Lil Dew 14 Posted June 6, 2013 Share Posted June 6, 2013 Hmmm, lemme see how the Miata guys did the turbos with the NB's(99-05). Those systems were returnless, unlike my 96, NA. Link to post Share on other sites
70-yenko-nova 12 Posted June 10, 2013 Share Posted June 10, 2013 ^^^ let me know.. GregE.. I talked to STS it WILL work but i think they use big turbos.. they wont help out with it though... they just want 2000 for the kit... assholes. they could be just trying to sell me a kit.the exhaust is EXTREMELY easy... the injectors would need to be pumped up and we need to figure out the MAP or w/e sensor is so we ca boost it.. i forgot what the part is (GregE remind me please) someone recommended looking into getting Cobakt SS parts. the tuning is what scares me. but if it could get enough fuel and the A/FR is good i wouldn't care. good solid 120-130 hp would be awesome.

austex04 48 Posted June 10, 2013 Share Posted June 10, 2013 GM should consider changing over to gdi, it would bump up mpgs and should raise hp to over 100. The downside with gdi would be carbon build up on the intake valves, but this usually happens to gdi engines that spend most of the time at idle. This way, you can get more power without the complexity of turbo. Link to post Share on other sites

austex04 48 Posted June 11, 2013 Share Posted June 11, 2013 Gasoline direct injection, like what Hyundai and Kia have on most of their engines already, and the Fiesta has gdi as well. Link to post Share on other sites
Ace 7 Posted June 11, 2013 Share Posted June 11, 2013 Oh and yes you are right it's why I wish they would release the Fiesta with the 1.0 in the US instead of hogging them in Europe. They are GDI and have turbo with variable oil pump with 2 stage cooling system for when you start the car up. Link to post Share on other sites
70-yenko-nova 12 Posted June 11, 2013 Share Posted June 11, 2013 DI is slowly making its way to more and more.. the next big step for vehicles will be DI and LI.... Direct injection is better power AND mpg... for example..the Cadillac CTS as a Direct Injection AND NON-direct Injection (in)direct engine produces 263 horsepower and 253 lb-ft of torque, while the direct version develops 304 hp and 274 lb-ft. however the Direct injection gets better mpg...Then you have Laser Ignition in the new Mazdas laser beam is delieved to a focusing lens that would take up much less space than a spark plug means new head and valve designs... as well. The laser beam can be split and what not which makes better burn...reducing emissions and getting better fuel economy. Another advantage apparently to the laser system is that part of the beam can be reflected to a receiver and used to gather data on the fuel mixture and the quality of the burn.

Lil Dew 14 Posted June 12, 2013 Share Posted June 12, 2013 http://www.bellengineering.net/product_info.php?cPath=5_20_277&products_id=29 This is an example of a simple FPR with a aux pump. That is how it has to be done without a piggyback or stand alone ECU. I knew it was done, but I didn't know how since my 96 was a standard fuel set up from the old'n days. Obviously, any FPR, a good one, with an aux fuel pump will do the job. This one is just a good looking unit. Again, good for about 5-6 psi, which is all you would really want on a car with stock injectors. Here is a simple website to use to gather the needed info on injector size and fueling. http://www.rceng.com/technical.htm Here is a great posting from a website called miataturbo.net. Keep in mind that the BSFC used for a Miata is .55. However, I would stick with .60 for safety sake. In most cases a turbocharged engine will have a B.S.F.C of .60. B.S.F.C is brake specific fuel consumption; How much fuel you are using per horsepower per hour. This means that the engine will use .60 lbs. of fuel per hour for each horsepower it produces. Using .55 for a Miata, which is a 1.6 and 1.8, seems to result in more accurate calculations. Most injectors will max out at 80-85% duty cycle and this is the accepted industry standard. Using these numbers as a guideline, you can select the approximate injector size in the following formula for your Miata to reach and estimated 200HP (engine) Est. Horsepower x B.S.F.C / # of injectors x duty cycle = lb/hr per injector cc = lb/hr x 10.5 200 x .55 / 4 x .8 = 110 / 3.2 = 34.4 lb/hr x 10.5 = 360cc Then determine the amount of fuel pressure you will have @ the rail to determine what injector will reach this desired cc level. Since injectors are typically rated at 43.5psi, this calculation will determine what they will flow at a higher pressure level: FUEL PRESSURE / 43.5 = New Flow Rate Square Root of NFR x Old Flow Rate = New Flow Rate of Injector At 6psi with a 8:1 ratio FMU we will have about 96psi of fuel @ the rail. We will use that to find an injector that will flow 360cc at 96psi. 96 / 43.5 = 2.206 sqrt of 2.206 = 1.485 1.485 x 265cc = 393cc That means at 96psi a 265cc injector will supply the needed 360cc (and a little extra breathing room) to reach 200 HP (165rwhp).

Lil Dew 14 Posted June 14, 2013 Share Posted June 14, 2013 ^^ Pretty much. Would you like the whole thing? I can post it. It is just large, and specific to the Miata, but can be adapted of course. Link to post Share on other sites
austex04 48 Posted June 14, 2013 Share Posted June 14, 2013 I'm sure someday someone will successfully turbo one of these, probably when warranty runs out. Maybe a turbo Spark will be able to keep pace with a Mini or Fiat? Link to post Share on other sites
70-yenko-nova 12 Posted June 14, 2013 Share Posted June 14, 2013 lol see i think imma just save up ton of money find a crashed spark... take psitons n rods out have them measured have forged ones made. the crank is probably good. then put turbo bam. Link to post Share on other sites
Rocketone 3 Posted June 27, 2013 Share Posted June 27, 2013 I'm sure someday someone will successfully turbo one of these, probably when warranty runs out. Maybe a turbo Spark will be able to keep pace with a Mini or Fiat? I own A FIAT 500 Abarth also and I can't see how they can make the Spark as quick. It would be interesting if they did though.

70-yenko-nova 12 Posted June 27, 2013 Share Posted June 27, 2013 lol the Abarth is 2 steps above the spark. give me time. =) I will work on something Rocketone 1 Link to post Share on other sites
Greg_E 211 Posted June 27, 2013 Share Posted June 27, 2013 Small amounts of nitrous should be just as good, and in small amounts you could actually last a while on a tank. The part I'm not sure about is the throttle by wire since it won't really open all the way unless it thinks it should be open so it may not trip the additional injection when you really want it.
