T3/T4 turbo on a DSM?

[randyknightjr]

i have a t3/t4 turbo im running on my 05 camry it think its a 63 A/R and i was thinking of putting it on my 91 laser AWD turbo. has anyone done this? im sure someone has. and next question will it help the car any? like is it a good turbo to put on my DSM. i have all the upgrades to my fuel system, full 3inch turbo back exhaust and a MAF/t with 3 inch GM mass air sensor. ( planning on getting a DSM link setup in the future) any comments, info, or tips are verry welcome. thanks!

That's because you're not really asking anything of any relevance. T3/T4 turbo is very vague, there are dozens of turbos that fit that description.

Is it a good turbo? We don't know since we don't have enough information. It might be a good turbo or it might be a Chinese knock off.

What are your power goals for the vehicle? What kind of turbo (more information) do you have? You'll need a different exhaust manifold and probably need to modify your exhaust. Be sure to have good engine management (dsmlink is great).

A .63 A/R T3/T4 is not enough information to know what the turbo is like. It could be one that maxes out at 250 hp or 500 hp, you need to find out more information about it. Why not leave the toyota alone? Is there something wrong with it that makes you want to rip it apart?

Are you tuned good and up to 20 psi of boost on your stock turbo yet? If not, don't waste your time or money on a different turbo yet. There is a huge power difference between 15psi and 20psi on a 14b turbo. If you are not maxing out the turbo you have there would be no gain in putting a different one on.

.63 A/R t3/t4 is about all i know about it, and it is a garrett turbo, so not a knock off. my laser is going to be my "race car" so if i can make alot more power with the t3/t4 i have then i will take it off my camry. i know it took my camry with a 2.5L from 130hp to 215hp with 7 psi. i have no tunnig on the camry because they dont make any tuning options for a 2005 toyota camry. so i cant go any higher with the boost without worring about my auto tranny. and having the only toyota camry of that body style that i can find with a working turbo system on it is gettig old and played out.

 

[marcmsj]

Your stock turbo on the laser can get you way past 215hp.

Just FYI you cant just switch turbos unless its mitsu flanged.

Since you specified T3 T4 you will need a Manifold. Oil feed/ Return. Water lines ( if water cooled) .63 is NOTHING so dont think your going to big. you will be fine.

Good luck

 

[randyknightjr]

yes but at 7 psi that turbo isnt even breaking a sweat on that camry!

 

[randyknightjr]

and i know the diffrence in the flages and understand all the mods i will have to do i.e header,external wastgate, down pipe, oil lines and change the water lines out so they will fit. what i need to know is will there be a considerable power increase if i use that t3/t4 turbo over my little DSM turbo.

i am tunned good at 15 psi and have the ability to be tunned good at 20 if i could get the turbo to push 20psi. the only time it has pushed 20psi is when the boost line poped off the wastgate one time when i was racing. i bought a boost controller but it raised the boost to about 17 or 18 psi for a few seconds in 3rd and 4th but went back down to 15 at about 6200 rpm. how do i get it to run 20 psi if i cant find a wastegate acctuator for 20psi? leave the boost line off the wastegate?? seems risky to me!

I say slap that mofo on there... crank the boost up to like 25psi and street race every SRT on the road... you'll dominate the streets.


as said above... why are you upgrading? sis you know you can get 350+ from a Big 16g?


also... DSM are not Yoda's... espcially a 14 year differnce in technology... I'm sure your stock ECU from the camry can adjust it's fuel and air to compensate to some extent.. your ECU in the DSM wont... it dosnt know how... or maybe you are trashing the crap out of your camry since you boosted a N/A platform.


also... on a stock 4g63, slapping a big Turbo on it will have crappy lag and the power will be usless unless ## going lightspeed.

because i dont have a big 16G, i however do have this t3/t4 and the camry is fine, the ECU in the camry is adjusting for it and thats not the problem with the camry. i cant turn up the boost because im afraid it will damage the trans. a/f ratio on the camry on the dyno is 12.3 to 1.

i need to know how to get the boost up to 20 psi on my DSM.

All you need is a boost controller.

It's all just a matter of having enough fuel, a way to control it and meter it, and tune correctly. You already mentioned a fuel system, MAFT, and DSMLink. Just add an intercooler and a clutch and you should be set. Of course this is a little simplified, but you get the idea.

well junior... 20psi on a 14b is not the same as 20psi on a t3/t4 Turbo.... those turbos have different flow rates. if you are looking for topend power, the t3/t4 will get more... if you are looking for more bottomend power... the 14b can get you into the 275-300awhp range.

also remember... if you put in that bigger turbo, you'll need a new turbo mani, DP, EWG and such... plus tuning will be a bi*** w/o Link.

IMHO... build up that 14b man.. it's much more safe and reliable...and should be able to push out 17-20psi w/o issues.

 

[beezwax]

oh and you never said what your goal is....

and getting 20psi isn't a goal

 

[randyknightjr]

well my goal is to have a bad ass street car that can kill all thease damn civic's and shit around here with H22's in them! i can hang with them now but i cant get past them in the quarter, p.s i hate 1/8 mile racing and i hate it when people call me junior!!im 24 years old im new to DSM, not cars in general. i have 4 of my ASE certifications and i went to school and hold a two year degree in automotive service tech, and have 4 years of hands on in addition to that. i post on here to get brain storming ideas, i believe there is no stupid questions when youre not sure about something, or you are confirming your thoughts. thanks for all your help. im taking my time about learning about turbo's and turbo cars. i know alittle and alittle is common sence, but for the rest i ask lots of questions.

now i bought a manual boost controller and installed it the way it is ment to be installed, and it gave me 20psi far like 1000 rpm's then the boost went back down to the wastegate set 15psi for the remainder of the rpm band. what went wrong? whats the next step to get my 14B to stay at 20psi? i know the turbo is good because i just had my turbo guy rebuild it a month ago, and it has no play.

On my talon, I just put a different T in the line that goes to the wastegate actuator and have the line with the BCS removed from it and it goes to 20-21 psi and stays there perfectly. That works a lot better than a boost controller ever has for me. I ran it that way both with stock exhaust and now with my 3" turbo back. All stock except for injectors and tune for E85 and then put in a 255hp pump later on.

i have a straight line from my intake to my waste gate actuator.so u are saying i should put a restriction tin that line? wouldnt that just delay the actuator ans do the same thing as that peice of crap boost controller that i threw away? not being a smart ass, im just asking.

 

[jrohner]

Having a T to bleed off pressure in the line makes the WGA (wastegate actuator) 'see' less boost than there actually is.

Use a hose going from your lower intercooler piping to the WGA, with a T in the middle of it; have the 3rd hose on the T going to your intake pipe by your airflow sensor. If you need another pound or so of boost, remove the 3rd hose from the T and leave it open.

You have to use a different T than the stock one, because the stock one will probably only get you up to 15 psi or so. A bigger line after the T or a smaller one before the T will also raise your boost slightly.

The other way to do it is to put a spring (like a carburetor throttle return spring) on your wastegate flapper, it's like installing a higher pressure WGA. I did this on my eclipse and got 19-20 psi with no T, just a line from the lower intercooler piping directly to the WGA. It takes a pretty stiff spring to actually up your boost.

 

[We're on Boost]

jrohner, you've got a heck of a dyno sheet there in your profile. You are making more hp at 4000 rpm than most people make at redline!
Makes me want to stick with a small turbo and look for a place that sells e85.

The wastegate controller you are describing, can you accomplish the same thing you are doing by using a bleeder type manual boost controller, like the Hallman?
