Well people that know me have heard me talking about doing this swap for years... and im finally almost done!! yay Its Yvonne's Car.. Shes owned it since she was 16 years old. *shes 28 now*. About 5 years ago i swapped out the wimpy 1.6L 12v SOHC engine and swapped in the 1.8L DOHC ripper engine. Now the time has come for some boost. Over the last 4 years i have been collecting the parts needed to make it happen, along with a whole parts Isuzu Impluse RS.... Well HERE SHE IS!!
after years of telling yvonne i will get around to turbo'ing her geo storm, and never actually getting around to it, i did it! All that whining and moaning that it will never get done finally paid off lol. I have been going hard on her over the past couple months... picking away at things here and there.. but she is now running again, fully boost equiped... Shes on all stock Isuzu Impluse RS engine management (ECU,Harness,sensors) also using the stock Impulse RS manifold/turbo/intake/Top mount interccoler/hood setup.
Still a few little things left over like swapping the Turbo instrument cluster to get the higher 8000 RPM redline and OEM boost gauge along with getting a working Tach (swapped to DIS/coilpacks insteas of the old Distrubuter. I also need to weld up the exhuast for aircare... (and then weld up a custom 2.5 or 3" catless exhuast after)... also replace the spark plugs to NGK coppers and ditch the heat range 5 platinums from the old NA setup. Hoping to get her out to the racetrack ASAP and get a bunch of runs out of her. Hopfully she holds together as she is a 10:1 compression motor..
I guess ill keep the boost low for now (8psi) and back the timing back to make sure i keep a hold on detonation. I have no real way to control stuff besides boost and backing the CAS back to take out timing. I do have a bit bigger injectors in there... but no compensation so im hoping that with the 1.8L and higher compression then the normal 1.6L low compression turbo it will work out. Stock injectors on the RS managment is 322cc... i have 350cc in there now. Seems to idle nice.. doesnt stick too bad... so hopfully ill get away with it. I have a SAFC II laying around i guess if i do end up needing to take some fuel out or add.
PICS
In the future there are many more mods planned.
-14b or 16g turbo
-Custom Evolution made manifold
-FMIC with SS piping
-Methanol Injection
-Engine managment & bigger injectors.?? Haltech? MegaSquirt? maybe some OEM chip burner software that will work with EPROM OBDI chevys (impluse RS ECU is a EPROM OBDI chevy based ECU)...hrrmmmmm
-Stronger equal length halfshafts and hubs.
-Slicks.
I do also have all the AWD parts sitting around doing nothing from the Impluse RS... hrrmmm...
