bone stock? as in stock exhaust, stock dp, stock intake, etc?

If so, that's your answer...

Open up your exhaust. You will change your mind.

Run however much boost you have enough fuel for. If your car is stock, you won't get over 1BAR though. fuel cut.

a 1jz with 10 psi will put 250-280whp down.. nothing crazy... thats why it feels slow..

and 3.5" is big... over kill i think.. the price isn't bad.. ss isn't cheap..

its all in your head.... Awd+450 awhp= fast.... Rwd+250-280 rwhp= feels slower ;) there you have it.

Slow and fast are relative terms, but a 1J with a few mods is hardly what I'd call slow. :dunno:


edit: I see your previous car. LOL, yeah. a 200hp loss in power would feel a bit slow I guess...

you can mod a 1jz all u want, but if your running stock twins.. it will be slow and barely get out of the 13's in the 1320.

Get a single blurbo. I advise a GT40-88R.

Deffinately. No replacement for displacement. Damn 5.0 quad turboed. that would be cool. lol

Yea the car feels slow because its stock. Do a few boltons and 1 bar and you will notice night and day. Shit even from a 5 min SAFC tune my car was night and day

I had a RHD 1J that is slightly modded and feels slow also. :rofl:

I sold it to my brother and hope to get some good hp out of it with the stockers so hit me back of what you guys do as well. My bro doesn't want to change stockers for a while so I am just doing other stuff for now. Car has only 51000 miles so I can see why he wants to keep them for some time.

maybe a big shot of nitrous :naughty:

check your compression ect, I have a pretty decent frame of reference on what fast is. Driven modded vipers, ferraris, ridden in singled supras, BPU RX-7, SR-20 datsun 510 (scary), and I was very satsified with my BPU 1j. Mods in SIG on a hard 1-2 shift im going sideways into oncoming traffic with brand new decent 225 series tires, i wouldnt call that slow.

Well 225 is pretty skinny though ;)

A slightly modded 1J is pretty slow and compared to the cars you post VERY slow.

But as for compression...that is a good place to start.

LOL, they should make BEASTLY V12, QUAD CAM, QUAD Turbos or TWIN BIGGER Turbos, reversed engines next to each other.....

that is , two 1JZ's, (6cylinders + 6 more, 2.5L+2.5L)) LOL then again, that wont make sense, 5.0L V12? :wtflol: :wtflol: :wtflol: :wtflol:
