Turbo Kit

yea would be worth it i suppose if you were building a race truck haha about it though.

 

You better do a write up, i was up at addicted offroad the other weekend getting my new bumper and Scott showed me the turbo system they have on their sas'd 4-runner! and now i want a turbo!

 

addicted has a turbo setup?? News to me..haha

and i will. As always.

 

Yea its pretty bad ass i wish they had a write up of it, btw Blackdawg what else would you need if you picked this kit up to run it? and that intercooler and mounting system would not work to well would have to grab a smaller one and re-pipe to toss it behind the grill!

 

There is a member on here, XRU, or both. I cannot remember. He has a 5vz. Out of Cali. Red truck. Was making about 450-475 with his setup. Has a video of him drag racing a Viper and beating it.

 

Here are a few pics that PSI Racing emailed me. Enjoy.

 

I have an account with CXracing and should be getting a kit in soon to work on the EMS.

Kind of feel bad posting though, as even though I can get the kit in fast, I'm strapped on time to install it. If there are any SoCal locals that want to see the kit in it's raw form, I'll have it lying around I guess. I want to have spare parts around as well as I want to play around with intercooler placement and such.

 

Yea so far i have this:

-Turbo port injector manifold from URD
-6 addition 380cc injector
-MAP ECU 3
-Walbro 255lph pump
-URD fuel rail tap
-Misimoto small intercooler
-custom IC piping

yea i saw that!

you have an account?? do tell?

I tried getting in touch with them just for some question on the kit last week..got nothing back.

And are you developing a EMS or something??

 

^^ I'm 99.9% that the AEM FIC I'm already running on my S/C is more than enough for the turbo kit. It has a MAF clamp, it tunes for larger injectors the same way the Emanage Ultimate does (directly intercepts the injector drivers and modifies the duty cycle, no "tricking" the ECU into doing this thus throwing off timing and lets one run much larger injectors), tunes live on the fly, uses AEM's nice data logging, has a switch for two maps, controls closed loop air fuels via an o2 sensor tap (works on both narrowband and wideband) and o2 tuning MAP etc etc.

If that isn't enough (doubt it), or people simply want more, I already have IS300 Plug and Play MS3Pro standalone setups, and can make 5vz versions. That would be good for guys with built motors going for big numbers.

Due to laziness, I'll keep the S/C on, but I don't like compound boosting, so I'll find a way to highjack the S/C's bypass to turn the S/C off when the turbo comes online, like the new VW twin charged motor design. The difficulty will be smoothing out the transition. Hoping the CXracing wastegate is very responsive.

 

Interesting.

However..do tell me how you plan on running a MAF with the turbo? the inlet is 4'' and there ain't a whole lot of room there.

Speed density is the way to go about it IMO. Much more accurate as it goes off Intake pressure as opposed to how much air is moving..


Id be curious on the MS3 setup. I almost did that to my supra..but decided to go with the MAFT Pro piggy back for speed density.

 

The kit does not delete the MAF, it has a MAF flange near the BOV- that is one of the issues I'm concerned about from my past tuning experiance.

If one does not want a MAF, the AEM FIC has a MAP sensor, and with data logging you can use it's MAF output map to simulate a MAF, somewhat converting your setup to speed density while keeping the CEL off. But thats extreme. IMO just put the MAF the same distance from the TB as OE, and get the BOV away from that area to avoid turbulance. Amazingly MAFs seem to do great even in boost. With the IS300, people run into way more problems putting the MAF pre-turbo vs. OE distance from TB. But thats why I want to run the kit- iron these things out.

The MS3pro can run speed density, mass air flow, alpha-n and blended maps. The mass air flow is not that refined yet, but I can't see many wanting to run that anyhow- but a blended setup much like the newere OE boosted cars could be cool. It also can run a flex fuel sensor and compensate. Its overkill for the kit in its raw form IMO, but for those going big, its a great EMS, especially keeping in mind the price point.

 

Yea MS3 is great for the price and cusomization.

and interesting. Did not know it kept the stock MAF. However..the BOV being right by it is an issue...Is it post MAF or Pre MAF??

and yea MAF does work i have no doubts. My supra was MAF to begin with. I just know you can get a more refined tune with speed density.

I would maybe try the FIC in MAP mode personally.

Let me know when you have a good product..id love to help test it out or anything. Very interesting kit you have for the SC.

 

Holy hells shits, I thought the 5vz went away...

Sweet build. W/e happened to your build? Ive been following for a while (not a member, just lurking):

my build died

i parted out all the big parts and sold the stock parts and car to the owner of our local Toyota dealership. He rebuilt it back to stock. Drives like a dream now. He let me drive it and lets me take it out for a spin some times whenever i want. Said he would sell it back to me when im out of school with a real job haha

i said deal. Motor still has the all the work i did to it. Just running stock turbo and fuel and quiet exhaust.

Just waiting to be unleashed.

the part out helped pay for my trucks resurrection and the Moab trip i rolled it at as well as my rear bumper and RTT.

i regret selling it a lot..but at the same time..i don't. It was a fun car though. and ill get it back someday

And yea i wish that guy would post more vids! i know somewhere he posted dyno results..just can't remember where..was awesome power band though. compared to most of the 7mgte's.

 

Videos.... quarter mile pull if possible. And Dyno (with stats). That would be awesome.

 

On Customtacos there's a kid (guy?) with a green 98-00 4x4, homemade turbo with meth injection, making something in the ballpark of 430/550 HP/TQ.

 

Don't forget that a flow straightener can also be added before the MAF to aid in reducing the turbulence. I have one on mine. About a 1/2" thich honeycomb piece. Even better if the BOV cannot be moved to far away, and are staying full MAF.

 

Damn... Just so you know, thats my dream car/engine.

 

what would you think about running this kit with low psi and no fuel or computer mods, how low would you need to run it you think? and then eventually upgrade the fuel and get a piggy back.

 

really? A MKIII supra and the 7mgte?? cool man! i loved it..and miss it..can't wait for another..someday.

no possible. The wastegate that comes with it has a 8 lb spring. In other words the lowest psi you can run is 8 psi. you can get by with 4 though without an ecu piggy back. but this kit can't do 4. 8 is the lowest.
