Fuel injectors were at 62% roughly. The 30psi pull we did next, the turbo decided to grenade itself. That run was not complete yet but it crossed the 740whp line roughly. Our goal was to max out this turbo in the 900whp range. Hopefully Precision warranties this turbo and I go back for some more numbers.

God damn !!! Just what ive been looking for thought i wouldve pioneered these turbos on the ka. Thats one clean engine ! Keep us updated and be the first the make 700wtq.

Whatc are you using for rods/bolts
& are you running thick wristpins ?

Keep us updated on the turbo, if precision doesnt have you covered im definatly going with fp's new 6466tz. Ive heard negative about precisions service before.

Exactly the same here. The turbo is less than a month old. The thing that keeps me returning to Precision is that their turbo's makes really strong power with small frames. Regardless if they do or not, I'm going to go back 6466 again.

I just looked at their site. I'm going to read up some more on them and try to find some reviews. I wonder how the spool up on them are.

Personally i think its a middleground between precisions 6466 and 6765 because precision does have the CEA turine wheel on thier 6466. 6765 is rated for 935 if i am correct and the 6466tz should spool decently faster.

Edit:Not to mention all the great reviews about fp's customer service

Cool. I'll definitely keep that in the back of my mind if I have to make a next purchase. I know the Evo guys managed to break 1000whp with the 6466. It most likely was out its efficiency range but they got the numbers they were shooting for.

I haven't personally owned a 240sx with power steering since I was 16. I have a really bad habit with deleting the units and persuading my customers to delete it also. Actually just the other day I drove a convertible 240sx that wanted to keep power steering after a swap and the car felt too light. The wheel felt too sensitive over bumps etc. I guess I'm just used to none power steering.

You(BoBaCk1) and I have a very similar simple setup. This setup has been running strong with my 6262 for years at about 25psi on the street. 25psi is all i ever needed to beat anything local around me. I've been working on a lot of customer cars (side jobs) because I was given an opportunity to go out west with a partner to set up shop, so I need to save a good bit. I hope it works out but the only way for me to find out is if I give it a shot. But anyways for stuff that your interested in. After I burnt up my twin disk on the street I had some down time so i ripped apart the engine to refresh it, then I started to look at Precisons Gen2's, and a rebuild for the clutch etc. My engine is a basic:

Crower Pro Rods
Aries 8:8:1 (.20)
11mm ARP
Cometic Headgasket
Stock Crank

Stock Head
Kelford 272's (not degreed)
Stock (New) Valve Springs - (Reason why I don't rev past stock redline)

Godspeed Intake
Stock Throttle body
Godspeed 50mm BOV
Ebay Stainless wastegate (I need to find the seller and post it because it really it top notch, its not Godspeed or EMUSA etc)
EMUSA 4.5" intercooler
EBAY FPR

T3 6466 Gen2(The 6466's has always been Gen2)

But yea that sums it up for the components. I have ebay stuff on this setup that has been making awesome power for years. I trust them enough that I put them on my customer cars. I dont trust the typical wastegate off ebay because they don't hold up so if someone reads this dont misread it and go buy an ebay wastegate.

That's good bro sometimes to be successful you have to take risk so I applaud you for making the leap of faith. Yeah I have a lot of fun driving around on 20 psi. I've beaten 2 600cc bikes so I'm happy. I've been thinking of upgrading my turbo also but I'm gonna try and push this 6262 to its limits. How is the spool difference between the two?

I'm currently installing an xcessive intake, converting to drive by wire throttle body and building a complete engine harness from scratch. I'm also hooking up traction control. My boy is building my harness for me and it's looking sick lol. I've been watching your car for awhile because our setups are very similar so congrats on the great power.

Thanks for the compliments. From the short drive to the dyno with the 6466 I swear to you it felt as if the bigger 6466 spooled faster to my 6262 which was journal bearing. On the 6262 I managed to pull 35psi before 4800 in my 3rd gear log. I haven't had time yet to do any logs on the 6466. The aem isn't reading my vss so I'm going to wire up the vss straight to the aem and run boost by mph. Traction control is a great idea for these cars with these power levels. I just purchased some Hoosier radials I'll be using for the streets.

That's nice to hear That's the turbo I was thinking of upgrading too. my Ecu is called proefi and the traction control strategies are really nice. Plus it also has boost by speed and time also.

Nice setup/power! Do you think the increase in HP between 7000-7200rpm is real or a false reading? If it's real there is a dip in the torque curve between 6250-7200rpm that you may be able to tune out.

I bet she is a handful with that much power. I think to be successful with the boost by MPH you will need to measure speed at the front tire(s). If you use the stock VSS your car won't know if you are spinning or actually accelerating. Maybe you could use an front wheel ABS setup? I think SMracing is doing this. Comparing your front wheel speed to your rear wheel speed and allowing a certain amount of slippage would probably be ideal.

I think its real HP reading. Atleast I hope it is haha. It never really crossed my mind for it being fake or any concern about the dip because the session was cut short due to the turbo taking a crap. This graph was roughly about 4-5 pulls into the session so I'm sure some fine tuning was still needed to get done. Thanks for pointing that out though, I'm going to make sure and pay attention to that next time. The boost by mph I was going to set up via AEM EMS was something just to help the situation out a bit. Ex. Lets say I'm going from a 40mph roll then I would let my max boost be about 12psi and not a full 25+ psi. I would gradually raise the boost up until about 90mph where I would achieve my desired boost setting. Thats how I imagined it in my head. Sometimes I live in a fantasy world so if you think this wouldn't work then please explain to me. I'm always game for learning and listening.

Re: 6466 28PSI

Rear wheel/diff VSS:
Lets say you are going 40mph and you lay into it. Your tires break loose at 50mph and your speedometer jumps up to 70mph. Your cars reaction to breaking traction is going to be to raise the boost. You could go back and reduce your 50mph boost setting and it would probably help you not break traction.

Front Wheel sensor:
When your tires break loose at 50mph, the speedo would still read 50mph and it wouldn't up the boost inducing more spin.

The rear wheel VSS boost control will be beneficial over no traction control. However, it will only be beneficial if you never break traction with your settings; the response when you break traction is more boost. The front wheel sensor boost control will limit your boost based on the actual vehicle speed when your tires break loose; this response is a power-cut compared to having no traction control and is the desired response. With the changing road/weather/tire conditions you will still get spin sometimes and the front wheel sensor setup would be superior.

I would imagine that the AEM could take input from front wheel ABS sensors. If not, the rear wheel method will be better than nothing.

^ that's how I have my car set up right now. Should be testing it soon. I bought a front hub and bearing assembly for an abs s14 and installed a sensor to it. Then for the rear I'm feeding of the vs sensor. As soon as the computer senses the different speeds between front and rear it knows it's losing traction and makes adjustments.

I would love to run those setups. I have to look into it because I actually do want to start putting power to the ground now. It was fun while it lasted spinning to the top of 3rd but this local dude is trying to come for my ass with this built rsx. I think he has pro efi's system. I was reading up some options in the aem and I have to decide what to go with. What do you guys think is the best option to go with in the AEM?

I actually am using proefi, and I love it lol. Of course I'm gonna be biased and say if you have a good tuner that can tune and set up proefi, go with that. I actually got to tune and drive my car last night. Proefi' traction control is amazing. I feel so confident with the car. I'm actually getting the car to get traction with 245/40/17 street tires .

All I've been hearing about proefi are good things. I'm going to invest in the unit. I can cheap out here and there on a certain things but for this concern I'm going to deal with the price. Can you tell me how you set yours up? Meaning what hubs did you use? I have a s13 with a 5 lug swap so I removed the abs.

Edit: I just read you swapped to s14 abs hubs.

I just wanted to give you guys a quick update. Precision contacted me after a month concerning the turbo. They mentioned that the reason for the turbo letting go is because a vacuum line made its way into the turbo during the pull. (Ugh, just my luck don't even ask lol.) Anyways, the tech who was working on the turbo cut me a pretty good deal since my unit was so new. He said to fix the turbo it would need a new center cartridge. The cost of that was $1200 but they prorated that for me and met me halfway at $600. They also offered me to add anything extra I needed at "cost". I added some gaskets, oil feed filter and a t-shirt. They ended up just charging me for shipping and gave me all the extra's for free. I was very pleased with their service and prices. Just the turn around time is a bit slow but no big deal... Time to do some body work and head back to the dyno for some fresh numbers.
