hello everyone new to the boards here i recently traded upto a 99 gs300. since ive bought the bone stock gs300 i have slammed it on tein coilovers and Black 2crave wheels and tinted windows. when i bought the car it had 200,000 miles and last week i was on the freeway and i lost oil pressure and the bottom end started knocking pretty badly.

i was contemplating a gte swap but i already have my race car and i just need my daily back. so any who i ordered up a new engine from one of my reputable vendors that i use for my shop. and 1 day later here i have a 03 is300 engine.

i swapped the motor out yesterday in the process i did a timing belt waterpump and alot of little gaskets, there were alot of broken connectors on my engine harness so in the process i repinned a few plug ends. so a few hours later the engine was in the car i used the is300 intake manifold is300 injectors,ignition coils. other than that everything is from my factory motor. so i was doing some reading bout the IS manifold that it was not the same so i swapped that back to my original intake manifold so now the only pieces that are from the IS is the fuel rail with injectors and ignition coils i was going to use the original coils and injectors but all my injectors were cracked and broken.


now the car doesnt like to stay running and i have no dash lights, no power to the obd port and cannot release the shift lock a]or pop the trunk and fuel door.

it sounds like a fuel problem to me so i was thinking these injectors are either bad or will not work with my setup any ideas?

i have checked the 40A main in the kick board and the 40A main under the hood they are fine

can anyone shed some light??

thanks a alot

ok i have found the running issue looks like where the FPR meets the rail the crush washer is a little beat up should have bought a new one so it will be here tomorrow so ill get that fixed and still no dash lights looking into that tonight.

Hey so you've put injectors off of 03 IS300 onto ur old 99 GS300 block?? Did they fit? From what i heard is that the 2JZ engine stayed the same as off 98 both IS and GS but sensors , manifolds, injectors changed as years passed? I need to change my injectors on my 98 gs300 and was wondering if they r interchangeable, if i could take it off of 02 IS300?? If anyone got an anwser for that it would be alot of help.

i ended up using the is300 injectors i just rebuilt them with a seal kit from ebay for 35 bucks. the injectors seem to work fine i did notice they did have different part numbers between my old injectors and these ones but all my GS ones were toast so i used the IS the car runs great now i had a leak at one of the injectors i found. but i pulled the the plugs and it doesnt seem to be running lean. but i do not have a wide band so i am not to positive
