DILLA400

sorry for the slow reply, the diagnostic computer at my school hasn't been running correctly. Once thats fixed ill run a diagnostic again.

i have the same problem as both of you.. im running a diagnostics on my car tomorrow so hopefully that will tell me something ill be sure to post if i find anything else out.

hey what kind of stock system is in your sc? is it the Nakamichi? I had the Nak. system in my car and replaced all the speakers and head unit after i blew the stock amp. I got mine installed at Ultimate electronics and they had to build a custom bracket for the head unit. almost all head units should work for your car. if you need the rear speakers i have the stock ones still

Thanks Jibby! that will be my project tomorrow..doesn't look like it will be hard at all..

Hey Jibby-first i just want to say thanks for posting this topic and answering questions, it's awesome, its been a big help for me! I have a question about upping the tranny line pressure. How do you do this? Is it really worth it? Have you noticed any downsides besides the hard shift from drive to park? Sorry if you have answered this question before, but i have read threw most of this topic and i can't find anything on it.

hey if anyone needs nakamichi front/rear speakers, sub, or head unit just let me know

hey, i have a '95 SC400 and i have the same problem, but at about 40mph it starts to whistle. its annoying! i have been trying to find out what it is and i went to a mechanic and he doesnt know either, if i find out anything ill let you know.

Hey deanp here is a link to what another user has done to his sc400 and hes gotten ALOT of power out of these cars http://us.lexusownersclub.com/forums/index...22&hl=jibby this is probably one of the best descriptions on modifications that ive seen on this site. it has helped me a bunch. the 400's are pretty restricted stock, upgrading the exhaust(rod millen, magnaflow,megan), ECU(Apexi,UNICHIP,Jet) , torque converter (if you are going to keep your 400 auto,this is a MUST for quick speeds of the line), intake, those and some other upgrades will give you a good start on how much power these engines really have. hope this helps
