Can anyone tell me how I can do this if you have any idea/ experience ( looking for detailed reply’s ) Dad isn’t keen on engine swapping so trying to work with what I have to get best performance something like this- Attachment: CC5F1DA5-66AF-46FC-9E12-34C8C059DE99.jpeg And, or this - Attachment: 93B804E5-966B-4C58-AA2A-52EC76D4123E.jpeg

Why bother when Suzuki already made two MPFI engines that bolt in? (G13b and G13bb) bother if which offer cylinder heads tat flow better and a superior bottom end? You’ll still have plenty of work ahead of you with the turbo work but at least let Suzuki get you started. |

Woah there a minute What does your dad have to do with this? If you need him (or his permission) to swap in a motor that literally bolts in, how are you going to go raising the thousands of dollars required to build a motor like this? What is your budget? Have you converted any engine to EFI before? Do you have fabrication skills? Does this need to be finished before you go back to school? The image in the first photo you posted has an Edelbrock performer manifold on it. That's a Honda part for a B16 engine. It's $860 locally. It will need an adapter plate made to suit the G13 head. It has bosses on it to accept injectors, so you could have them drilled, and then have a fuel rail made up to suit the injector spacing, but I'm going to suggest you could easily end up $2.5K in on the inlet alone by the time you get a fuel rail, injectors, throttle body, adapter and machining. To complicate matters, this inlet will eliminate your thermostat housing. I guess you could use a rear mounted thermostat from a swift to get around that, and the engine would probably prefer that too. There isn't a bolt on manifold to accept injectors for an 8V G13A, the closest was the TBI Escudo manifold, which is nasty. (TBI doesn't play well with boost due to low fuel pressure) so this is a substantial hurdle to overcome. That doesn't take into account the hot side, turbo, intercooler, exhaust, fuel system or engine management. It's well understood that G13 engines don't like boost, any more than 6 psi and you're going to have problems. There is a vendor in the US that will convert a G block to closed deck, you can read about it here: viewtopic.php?f=4&t=56862 , but unfortunately this thread hasn't been updated in a long time. All up I'd say this is a $5-8K project, which is a lot of coin to hear you car go stustustustu. What problem do you need a turbo to solve? Why do you need substantially more than 100HP? Have you considered (and budgeted for) the consequences of all that torque on the rest of the driveline? |
