I'm running between 15-18psi

Good info. Thanks. I wasn't too sure. This is my first time doing more than just the basic bolt-on upgrades of exhaust and intake, so I'm trying to figure it all out. And I found out that another issue that is making my car feel sluggish is the fact that my rear differential is going out so it's...

I'm sorry if what I said is confusing. I'm not trying to adjust fuel. I'm trying to get my timing correct. I was told that after putting in bigger injectors and having more air flow, I would have to adjust my timing to compensate. Is this correct?

I have a 7mgte that I have been slowly upgrading. SP61gt DBB Turbo RC 550s Lexus AFM 3in Exhaust PWR Radiator I just recently put in the RCs and lexus afm. It ran great for a about a week and now it seems to run a little sluggish. I dont have a wideband yet so I can't read my A/F...

when my rear end was wiggly and stuff, i looked and found out my rear subframe was cracked in 3 places......

But wouldnt it flow better through a t4 setup?

how much boost are you running and where do you see full boost? I'm curious because I want to see if it'll be worth it for me to go with a t4 setup or stick with my sp61gt dbb bolt-on turbo

well you do need to get a walbro or mk4 fuel pump. but you also should get an aftermarket fuel pressure regulator to adjust fuel pressure

build specs?

slap a turbo on lol

Can you post some videos of some pulls?

i only wish i had power like that. im trying to work my way up there

yes you can you can get one from the junkyard or someone on here

Well I haven't had any issues with it yet and I've put like 7000 miles on it. I think everything except the turbo has went out actually lol. But I have been having thoughts of going with a T4 setup lately. I dont know why

I was running street tires up front and the khumo ecsta v700's in the rear

well i plan on slowly replacing everything. but i just couldnt find aftermarket axles so i was just curious because i always hear of other cars needing to replace their axles for higher horsepower levels in competition

So the axles on our cars wont ever really be an issue with drag racing or drifting? I will probably max out my car around 600hp at most.

I'm curious to know if anyone selld aftermarket rear axles for the MK3. I've been looking and haven't found anything yet. I will be drag racing my car and maybe getting into drifting later on and I want to make sure my drivetrain is up to it.
