Hi, Guys Im New to Club Lexus And I really wanna put a T70 in my SC400 but The whole electronics and tunning thing scares me ****less lol, i think ima mess it up for some reason, so yea my question is , Can I use the stock injectors and ECU and run that turbo?
I only run 6 psi now and smoked many cars in the 350 hp range. I haven't lost yet.
You might need to have a hp goal to decide which turbo to go. And I think you might need to start another thread to avoid jacking Ca12los69's thread.
go to www.lextreme.com then www.google.com and LEARN about what a turbo is before asking that question.

Yup I would back off on the application unless you have plans to continually build the car up and up.
Like was mentioned, start with a Horsepower goal, a realistic goal.. Size your budget up. Then research.
Something like 350-400hp is reasonable with a budget of 4-5grand.. Less if you get or skip certain things.
Say you run 350hp, you don't have to replace the tranny, you can get away with alot of factory components that otherwise would need replacing because of the newly introduced friction/force from your power adder. Engine has to be solidified when that kind of power is introduced. A more reasonable power addition is cheaper, and well, easier overall.
It does take alot of homework to do yourself,.. even to pick the right parts. If you have the money take it to a tuner, and work out the details. Leave it with em for X days (week) whatnot.. and pick up your new car done right =)
But, half the fun is in doing it yourself.

Hey Carlos! How is the car running? I have not heard from you for awhile. My piggyback is going up for sale if you are interested. I finaly completed my 6 speed swap! A supercharged 6 speed Sc400 is loads of fun. I should have my stand alone any day and will be boosting to 11 lbs. this will be my indermediate step. Just shot this video today.
FYI these are my track wheels, CCW w/MT ET streets and front skinnys.
Yes I know I bounced off the rev limiter a little. I really was hovering it around 4000-4500 RPM but it keeps climbing up. This is just thru first gear, It will throw some more down if I hook second hard.
Enjoy

i know i'm new to this board and this thread, but...
In the landcruiser wold, we are turboing the inline 6 1fzfe motors and also there is a TRD supercharger available for these motors.
One problem we were running into was saturating the MAF sensor and throwing it into openloop soon. We had a member machine a larger diameter MAF housing and replace the stock MAF with a larger unit.
This eliminated the quick saturation we were seeing.
may be worth looking into.
here is the thread for anyone who is interested: http://forum.ih8mud.com/80-series-te...f-gen-1-a.html

Update:
I have recently machined the blower pulley down to about 61mm.
This has resulted in about 9 PSI. I initially had belt slip problems, but I just finished added another idler and that has solved the slip. My wideband A/F meter shows 10.5 at peak boost. I am also running 70/30 water-meth injection from 6 PSI up. I do not hear any knock and the engine is pulling very strong. 10 PSI is achievable I believe, but this would be cutting it close without engine management. The drive belt would probably contact the radiator hose as well.
I have a BEGI RRPFPR and a walbro high pressure pump hooked up at battery voltage. This seems to be doing the job, but an aftermarket ECU and injectors will be needed for reliabilty and more timing advance. I had a chance to drive a stock LS400 and the power difference is amazing. It was all worth it.

Great news Carlos! love the progress. Just a FYI, I may replace my full ported M90 soon and that would probally give you a extra 2lbs.
I have a stand alone coming soon, Just trying to locate injectors.
Anyways I am really loving your project, great progress.
