to4 turbo question

[ridebmx]

Okay I was wondering what else would be needed if i was going to use a to4 turbo on my 97 s14? Or would it be laggy...second question is where can you get a rebuild kit for the airesearch to4 a/r 60 turbos? thanks alot in advance, also is the best exaust manifold? And finally, what downpipe should i get?

[Jeff240sx]

DO A SEARCH!
Generally, a t4 turbo is huge, and will be very laggy.  I'd venture to say that 90% of all KA-T cars are t3/4 hybrids.
Airesearch is a garrett turbo, so check with garrett for the rebuild kit.
Manifold is whatever you think you should get.  Some people like log style, others like runner style.  I have the revhard, and it's runner style.  And I like it.
Downpipe.  There is not a current downpipe available for KA-T setups sans a kit.  You'll need to custom make one.
Sr20det downpipes bolt up to the resonator, and remove the piping forward of it, and the catalytic convertor.  But it will stop exactly where the catalytic convertor stops.  I was prepaired to make a 90* bend to the sr downpipe, but it didn't help in the least.  I found out the $190 way.

well i did a search and i didnt get much help, all i really seen was stuff about the t3/t4 hybrids, and the reason i asked it is because my dad owns a salvage yard, and i could probably make my car turbo for cheap compared to going n/a which i would like, but with going to college i have no extra funds...anyone have any ideas on what car/truck/semi/n-loader/skidder, would have a turbo that i could use?

the ford 7.8l desil turbo uses a t04e turbo...quite nice....a t4 is normaly for higher psi aplications...so if ur not plaing to go all out...get a t3 or t3/t4 <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=':D'>...i know all about junk yard turbos...if u see me online hit me up <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/alien.gif" border="0" valign="absmiddle" alt=':alien:'>

well the t4 that i have is from one of the many spare new john deere 8.1L diesel engines we have for our n-loaders, and i actually found one that has the t3 turbine housing, but the "wheels" (not sure what the exact term used is since im new to this whole turbo thing) have play in them, it spin nice and all, but they wiggle, where as the t4 doesnt, so could i just change the t3 housing and put it on the t4<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>? i also found a banks turbo i believe from a 93 chev 6.8 diesel, but i dont know the size of up because i am even less educated with the sizes of their turbos, basicly it would be nice to have some help from someone that knows alot about turbos, and it would be nicer if they lived near by, but as far as I know the closest Zilvia member to me is Yenpit, and thats like 7 hours from me...haha...anyways, hope you guys can imform and help me

[240racer]

with all respect for Zilvia, it isn't the end all be all of information. I would recommend searching around in other corners of the internet. &nbsp;turbos are turbos. &nbsp;you have a 2.4 liter engine, that's imprortant, it doesn't matter if it's a KA or a ford. &nbsp;The T4 is big, unless you are running lots of boost with high hp, then don't bother. &nbsp;I have a ct-26 from a supra/mr2/celica &nbsp;try that, I like the size otherwise the T3 in the 300zx is nice. &nbsp;I wouldn't go bigger then T3/T4 unless you are making more then 400rwhp
it sounds like you are on a budget, so you probably can't afford to make 400rwhp on a KA

[ridebmx]

but my last question was if i could take the t3 exuast side off and put it on the t4? I found a t3 outta a 85tbird last nite but the exaust side was alittle cracked...and the turbines didnt spin real nice, so if i cant switch the turbo housings ill just have to look at other ones....

[boosteds14]

i straight t4 is great for high boost. lag is ok. but lag means more power

it depends on what exactly you want out of a turbocharged engine. low end power, high end power.

with the right specs, the t4 can be just like a t3/t4. i know my turbo, .82a/r and stage V wheel t3/t04e has the same characteristics as a t4. plus the t3/t04e can make up to 500hp on our 2.4L with the right specs. that is why 90% of KA-T's use them over t04's. its the best of both worlds. Lag vs. low end

[sykikchimp]

Be wary of Diesel turbo's &nbsp;I hear they come with outrageously large exhaust housings... &nbsp; I would looke for turbos from the Z31's or turbo coupe fords. &nbsp;Also the Buick GNX's had t3/t4 hybrids.. &nbsp;only problem with them is they had a non-traditional round 3-bolt inlet flange that would require a custom manifold. &nbsp;Also a lot of Volvo's had turbos but they had really small exhaust housings, and wouldn't be good for much boost.

Either way, try to find something in the t3 - t3/t4 range.

[ridebmx]

well i have the t3 turbo apart...wholey fucking pain in the ass!!!!! it took me 4 1/2 hours to get the damn exuast side off...and the only thing about the exaust is im going to have to make a plate to bolt a downpipe to, and the flange where it bolts to the manifold is t/3, hope im doing this right, but i guess we will see what happens...the biggest bitch was getting the exaust side unbolt and off the cartirige...now to take the t4 apart and see if it will work...another question...would the a/r 60 be fine with the t3/t4 i am attempting to make? thanks alot so far....ill try and get some pictures later tonight if you guys wanna take a peek

[ridebmx]

well i have the housing off the t4, so now i have to put it back together, still wont know what it will be lot untill i get it on my car, which wont be for awhile, but i cant see why it wouldnt work...




update...got it all together fine, so im assuming it would be a t3/4 a/r 60...








I was wondering about the ecu, since my car is a 97, do i still have to get one out of a 95 or 96, or does jwt do the 97/98 ecu reprogram, are there any other options, thanks alot

[nissmo240sx]

hehe. this is funny. &nbsp; &nbsp;Ive had my KA turbo for quite some time now. &nbsp; let me tell you, &nbsp;straight t4 is not a good choice if your going to boost 10psi or less. &nbsp; &nbsp;i have t3/to4e 50trim, &nbsp;.63 ar stage 3. &nbsp; &nbsp; &nbsp; I WILL SAY THAt for the 240sx KA motor &nbsp; the E compressor is not efficient for boosting up to 10 psi. &nbsp; &nbsp; &nbsp;if you want to be efficient and get the maximum horsepower and torque from your setup at 7 -10 psi boost , &nbsp;you will want to have a TO4B &nbsp;compressor, &nbsp;particularly the H3. &nbsp; &nbsp;I dont want to get into the exact specs cuz im freakin lazy, but im on my second turbo after i tried the stupid t3/to4e trim for my 7psi setup. &nbsp; &nbsp;ALL ABOUT TO4B H3 for 7psi. &nbsp; &nbsp; shit fucking ROCKS . &nbsp; &nbsp;E compressors can &nbsp;eat a Deezy for low boost applications. &nbsp; &nbsp; &nbsp; you'll have fun when u complete yur setup . &nbsp; &nbsp;Lizzate

ECU:
as long as your car was made in 96, the ecu is a 96.

i have a 97 that was made in 96. therefore the ecu is a 96. JWT reprogrammed it with no problem

i had a t04b H3 compressor on my setup at first. but i was boosting to high for that turbo. i then went to a t04E 60trim. big difference.

the t04b made big power low end with low boost, like 12psi. i would light those tires up as soon as it hit boost. but it suffered top end

the to4e was quite different. i could not let the tires loose like before. maybe because it was alot more laggy. but at 12psi, the power was just not there. but at 20psi, it was a huge difference from the t04b. after 15psi, the E comes alive and puts to shame the B.

[ridebmx]

how do i know what exactly i have, all it says on it is Airesearch T04 A/R 60, and thats it, to make sure would i just have to get the 300zx fuel pump, and 756 injectors to run 15 to 20psi, along with the intercooler and what not....anyone have a picture of where the wastegate connects? ive been trying to figure it out but i dunno, its just not working, haha, like i said before my knowlegde on turbos is very null...thanks

Almost every turbo ever made was originally made for a diesel. &nbsp;This is why we often use the small exhaust housing (T3) with a larger compressor housing (T04). &nbsp;In general, diesel engines have more displacement (more exhaust) then a gas engine making comparable boost and power.

Big turbos = good effieciency at high flow/boost
small turbos = good effieciency at low flow/boost

you have to decide what you are shooting for.

[sykikchimp]

You do not want to try to boost 15+ psi on a stock bottom end KA.. &nbsp;I personally (just b/c I like to be safe) would not push above 14psi on the stock bottomend. &nbsp;

Even if the turbo you have is an e compressor it will still work for the low budget setup just fine.. &nbsp;don't worry about it right now. &nbsp;get the car running, and then if you decide you want something different, then do it.. &nbsp;lag is not a bad thing.. &nbsp;lag is just the engine without boost.. &nbsp;With no lag you have no Huge torque increase to look forward too. &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

found a fmic today, its from a 92 dodge 250 turbo diesel, sure it might not be as good as a new one, but when its free, and i can mount it in there, why the hell not, now all i need is a bov, wastegate, injectors, fuel pump, manifold, and to get ecu reprogramed, and the little stuff like guages and what not....hmmm, wonder what other parts i can find....anyone know of any other cars/trucks that would have some of the parts i need?

EDIT-i neglected to say that we had 2 in stock that were off, and im sure that there are some intercoolers still out on cars....we have something like 2500 cars in the yard, plus all the stuff that is in inventory, and heavy equipment....

756cc injectors for 18-20psi??

i would not do that at all. 550cc injectors handle 19psi
the 756cc are good for 27psi. they are a over kill for the boost uu want to run. plus the idle is not that good at all.

Make sure you pressurize that IC to make sure it doesn't leak before trying to use it.

where do you get 550cc injecters and cobra maf...thanks...

[email protected]

[boosteds14]

wait,
you want to run 550cc injectors and a cobra maf which is good for 18-19psi of boost and u are going to run a junkyard intercooler?

i sure hope you understand that when you want to obtain high boost, u can be CHEAP! you will need to buy top line products with a reputation so your setup can be reliable. get a nice greddy or apexi intercooler. i mean u want to spend money on turbocharge motor, might as well do it the right way.

i hate to say it but it is true and dont flame me but
"A Budget Turbo Kit does not go with high horse power"

if you are going to run high boost, atleast let the motor get the best of the best.

[ridebmx]

well im pretty sure that that intercooler is capable being effiecent at 500hp, from a dodge cummins turbo diesel, i would have to look at the magizine my dad has that has upgrade kits for his 94 dodge 1 ton wrecker, (same as a truck, different rear*hence*wrecker)and iirc they dont change the intercooler, but i can check tomarrow to make sure, and i think that i would be probably running 10 to 12 lbs boost to start, then stage 2 would be tearing the motor apart and getting a nice fmic....

EDIT-looking at around 2600 right now....could possibly just make it 800 more or so and get the fmic since my car wont see the road till may....

List.

turbo-have
bov- havnt decided which one..roughly 200
wastegate-240
fmic-have or 800
550cc injectors-425
cobra maf-375
ecu- 600
300zx fuel pump-125
downpipe-200
boost guage...?
manifold-600
and i think i have everything else

damn...looks like im going to have to actually work more than 9 to 2 five days a week...that or go for low boost....but blah...i dont want that...guess ill wait and see you keep you all informed

[Jeff240sx]

Just FYI. &nbsp;I have nearly $3k invested in my turbo. &nbsp;Granted, I didn't go buy the cheapest I could have, but still... I have the best equipment available. &nbsp;Stuff that Boosteds14 uses at 27 psi, and I'm only running 4. &nbsp;But thats not the point. &nbsp;I had a turbo, wastegate, manifold and bov in hand at only $2100. &nbsp;But then I needed many other things, so now I need another $400 or so to run 6.5psi. &nbsp;Just letting you know... it will be expensive, and then... once you get boost, you'll want more, and it will get exponentially expensive.

what are you using for fuel managment, you need a re-tuned ECU or something

yes i know i would need a retuned ecu, i pretty sure i decided that with all the stuff i wanted, it would almost be better to get a kit, so i guess we will see in the days to come, thanks for all the help guys
