I know this is a fairly old thread, but I just wanted to give an update on the topic. I have been running with the CBR 600 F4i coils in a waste spark setup with a MSD DIS4 CDI box since December of 08 with great success. Although I cant say how it will work in boosted applications, I have tried...

The Number for the dark blue / green 250/251 injectors is 23250-50020

According to Lexus, all the 1uz's 92-97 (didn't chech 98 and up VVTI engines) got the 251's. Only the 90 and 91 LS's had the 220's

Ok, So I just went and did a little bit of research and found that the 220's were only used in the 90 and 91 LS400 engine's. In 92 the SC400 was released and all the V8's (atleast here in the US) came with the 251's.. This explains why I have never seen an LS400 with the 220's, I have yet to...

I here so much about the LS400 having different injectors then the SC400 and yet every LS and SC that I have had my hands on have had the same injectors... What gives here??? David, I have yet to see an LS400 engine with the gray tops, have you verified what years they were used? I have...

No, there are no direct replacement sensors that will work unless a "little Black Box" or sort is made. Unlike typical AFM's the Karmon Vortex type meter sends out a digital signal to the ECU where all the others send out an Analog signal. The ECU monitors the frequency of the digital signal to...

Yeah, you should be in the low 200hp range at the wheels.

Hmmmm, This sounds identical to the issue Matt (RedPhinonex) was having. As it turns out, it was simply the AFM module was not seated correctly in the AFM housing... His was doing the pretty much the same identical thing, it would miss anywhere other then idle and WOT. He had after going over...

If you look in the picture in post #11 you can see that the bearing is a rounded nose bearing. It is the same bearing that Im running on mine and it also happenes to be an actual toyota bearing. I dont remember what model Toyota, but I do know that the part number of the bearing that I have and...

A new intake is probably the first order of business... The stock lower half as been found to be a big airflow limiter... I dont recall if Justin had dyno'ed his car with the lower section that he made, but I do know that he said that you could really tell a differance in the top end and this if...

Bolt the suspected problem head onto to block and torque it down and see if the cam spinnes smoothly then... I've had numbers of heads that were very tight when relaxed but the cams spun like they were on ice when the head was torqued down...

Yeah, john what rod said about the wood to make a small ramp is how I get my jake under my car..... Those air bags are nothing new really... via compressed air, they've been used in the trucking industry for years now... I remember the first time I saw / used one was back in 94 or 95 and even...

Yeah, the timing is high to help stablize the engine. Plus the ECU advances time when the engine is cold. From what you said, while in diag mode it went to 10* which is exactly what it should be so all is good there...... I've never heard of there being issues with fuel return. If it were...

That is the correct gap, plus the OEM ignition system has proven strong enough even if that gap were to big, it should still fire the plugs with no problem...... This is not an issue with his problem. For starters, we had gone over diagnostic codes that he had. There were no diagnostic codes...

Yeah, your sensors should be fine where they are. I have mounted several wide band sensors in the 10 to 20 inch range after the turbo and have never had a problem to date.

Your welcome. I also really positive now that that sub is from an 86-88 car cause it also has the early style swaybar endlinks. Chance are that diff is going to need to be rebuilt. Luckily though, the disks, plates, and springs from toyota are not to badly priced and they are pretty easy to...

I beg to differ on how weak the W58 box really is.. They are a lot stonger then what most think. I personally have laid down 473 rwhp in my supra on an old turbo set up. Jake as laid down close to that power too... Its all in how you treat it... The point that MPW made about the button...

Actually it could be, but its not worth the effort to do so when decent standalones are cheap enough now-a-days....

They are not your usually dizzy's with electronics and what not like older cars.. All you have to worry about is the caps and rotors.. They are very simple to change, just remove the plastic covers on the engine and there are 3 screws that hold each cap on and then 2 screws that hold the rotor...

Hella deal for $150.... From the looks of it and its lack of two braces, it came from a 86-88 car.. If thats true, then its either got a 4.30 or a 3.909 rear gear depending on if its from a turbo or N/A car. About the bracking that I said in my earlier post, the are known to crack around the...
