How is 12 lean? What are you running under full boost?

Definitely a great technique for larger turbos. There are some turbos that take up to 10 seconds to spool, so in those cases yes. Otherwise there are better methods as mentioned above.

I am thinking about changing my fuel pump because i have the little rpm hop that others have talked about. It just doesn't idle super smooth and also can cut out a bit under full 14lbs of boost. It took me 7 months to build this 1jz and i really don't want to destroy it. Well, i have done a...

i know, but i am also not redlining her, i have only taken her to about 4700rpm. That was when i had the bad thermostat in. The last fuel map showed 12.5 under full boost. I am being very careful. I am guessing it is just the 7m fuel pump. Anyone else have ideas? It has the little rpm bump at...

Mine have been super erratic. The first fill up after the swap i calculated about 21. I was extatic, after that it was like 16. Since then it has been between 12 and 17. I just changed my thermostat to hopefully help, but i am kinda worried. I really dont drive with a heavy foot, so i was...

HAHAHA! :aigo:

Is the Bosch 044 just for people going for more then 500hp? Is it more reliable. I thought the walbros were kinda the standard.

Hmm, i am having the popping issue also. Only happens under low rpms. Over 1700 you don't feel it, but if you are cruising down the street at like 1500 or lower, it lurches a bit every about 2-5 seconds. Kinda annoying. I have a car that was originally a turbo auto. At idle it pops about every...

Here are the pix of mine. WIth a clean denso number, 128100-46080, second number:1280000-9294. Both before and after the rebuild. Sadly it looked perfect before i was stranded in a parking lot at night and i had to take a tire iron to it, so i could get home without a tow truck. :)

i wish it could have been confirmed before i spent a week trying to figure it out. From what i dig up, they were not threaded. People have shown some that were, so i am seriously confused. The rebuilder shop had no cross match for the denso number on my 1jz starter. I wish someone had pictures...

Interesting article that is sorta on topic of this thread. http://www.mkiv.com/techarticles/filters_test/2/ I still have the hardest time understanding how the Apexi is a zero maintenance filter. Anyone else have views on their power filter?

Yeah, i am not quite sure where it comes from. I have only dealt with it once so far. It only happens when i drive and it is only a few drips over a 10 minute drive. It is hard to troubleshoot when it is kinda random. But thanks for the feedback. This car should be all original, it only has 100k...

I already have everything else, i just need to bolt in a new filter. I was wondering if anyone had studied the perfect size or cone angle for our engines. Do you have pix of this filter that he hooked u up with?

I wouldnt trust this filter. It is from a cheap intake upgrade kit. I slapped it on simply because i did have a new one. Anyone else have ideas on the optimal dimensions on a air filter? K&N has a ton of combinations.

I was looking for a replacement filter for my 1jz. I have a crappy paper one right now. On my na supra i had the one from a K& N kit, but i just need a filter. I found there catalog and there are a ton of filters there. http://www.knfilters.com/search/univcone.aspx Anyone have an idea of the...

All good, i have been driving her for 2 days. Very good starter. I dont think a Japanese one would be 200 bucks from Toyota. This one isnt even in the American denso catalog.

I was hoping for a simpler fix, meaning less expensive i guess it is just the front seal. But the car hasnt had that much use,i was hoping i could fix the stock ones.

Well, i have now driven a targa for about 3 weeks. It is winter and it rains a lot. I have noticed in hard rain, sometimes i get a few drips from the corner of my targa, where the window meets the targa. I have tried to put the window as far as possible. Anyone know of an easy fix for this? It...

I had it rebuilt. It is all pretty now. The shop did it pretty inexpensively, being that they had to track down some random parts and rip apart a few other starters to get it to work. It was 157 and it took a day. I will snap a picture before i put it in. Everything was shot internally. They...
