Celica Forums General Discussion Exterior Question about turbo kits, and apexi vafc controller

Hi people,
Ok im in australia and am looking for a Turbo kit for my celica. I just basically want a low boost set up with stock internals for now. Is it better to order a complete celica Turbo kit from america or japan (i know they have) and get some1 to fit it over here, or is it better to have some1 make me a custom kit from scratch?? also if anyone has purchased the kit from america or japan how much did you get it 4?? because i have been quoted around 10+ grand (aust) to get it done from scratch. (keep in mind australian dollar conversion rate wen telling me how much you guys got it 4).
Secondly can the use of an Apexi vafc controller, shift the point of lift under acceleration and decellereation on my engine without the need of power fc? i know my mates type r's can do this without computer upgrades and their vtec cuts in at 5300-9000rpm. Im sick of redlining at 8200rpm then dropping back to 5500rpm into second and having that lag before i hit lift again at 6000rpm.
sorry for the long questions
Thanks

isn't a vafc a vtec controller?

Lowering your lift point will make you lose hp.

learn to shift better.

the better drivers can land the 1-2 upshifts at 6300+ rpms.

sounds like your shifting too slow. I'm not trying to put you down at all.

You cant lower lift engagement past 6K i've dont it and tried to go even 50rpms lower WITH the apexi power fc and you loose massive hp, were talking like 15 whp here people, the camp profile for lift is just too agressive.

if you still think your shifting is fast and getting upshifts any higher than 5500 rpms I suggest you go to the racing forum and watch Lucky317's vids of his tach it will show you that its possible.

In addition, getting the power FC is another option (should you choose to not work on your shifting) and can extend redline to what ever you want, we've found 8600 to be optimum.

shifting at 8600 rpms and "granny" shifting I can still stay above 6K on the 1-2 shift, however i traditionally land it at 6500ish rpms now with no tire spin.

lastly vfac wont work its for Vtec not for toyotas, and if you were to try to tune simple air fuel ratios on it the stock ecu may over ride it. Since your in australia, I dont know how the ecus are tuned out that and it may or may not work for air/fuel tuning, but in the states they do not work.

well in my experiences, custom kits are cheaper since companies will add on money for profit often, and you can get the parts individually at your own pace and look for deals. for example, here in america we have a kit made my Stafford Fabrications which is the #1 kit out there right now. the gts is still under development i think, but it should be released soon if im not mistaken.

the stafford kit uses a t3/t4 hybrid, and if you have intermediate knowledge about Turbos, they aren't efficient for the levels of boost for stock internals. right now im planning on running a T3 Super 60 trim Turbocharger, which is pretty efficient around 3000 rpms - the range of where i do my driving at. a t3/t4 may work good, but not as efficient as it should be at 6-7psi. basically what im saying is, pre-fabricated kits straight up come either with everything or without everything, whereas custom kits you can include everything you want to the cheapest prices you can find and you can use the parts of your choice. though pre-fabricated kits have a significant amount of r&d put into them, you can get a custom kit working just as efficiently if you spent the time to effectively plan it out.

like Illusive said, learn to shift faster. 5500 rpms is real low. usually on the 1-2 shift you want to land in lift so you will get no "lag" that you are experiencing.

v-afc's are specifically for vtec engines, a technogoly our cars do not have(although vvtl-i is somewhat similar). you would need the Apex'i Power FC to manage the fuel system tweaks, etc. after you install the Turbo, no matter how low of a PSI you are running. more air into the engine means more fuel which means tuning.

you have a 2000 so lift comes on quicker and with our rev limiters we can land in lift 1-2 jsut need to go up past red line

Thanks for the advice and help guys.
yea i am conservative with my shifts for fear of hurting my engine, gearbox, clutch etc. but i will check out that vid on shifting.
how much does the Turbo kit cost and isnt there a xs kit or something?? whats that all about

the xs kit has been known to cause problems on the gts. i must say though, its a very nice kit with everything you could need including a standalone fuel management system. its pretty pricey too..around 5,000 i believe.

the stafford kit has been installed on a few GT's and GTS's and so far so good was the last thing that I heard. you definately would want to check them out. http://www.staffordfabrication.com, or you could do a search around here to find some more info.
