t25 turbo set up

[Tyler]

okay, im going to turbo my KA with a t25 from a redtop. and im just going to run low boost(8-10psi) because this is my daily driver and i dont plan on racing anytime soon with it, cause im builing a track car for that. so i was wondering around what WHP you think i will be able to make with this set up. i would love to have around 230 at the wheels. the motor is all stock internals.

-t25 turbo(freshly rebuilt)-ssac bottom mount mani-hks ssqv bov-3 inch sr downpipe-370cc sr injectors(will i need bigger?)-ebay intercooler-mishimoto rad and e fans-emance ecu tune-Walbro 255lph-2.5 inch exhaust

Thanks, TJG

at 14psi with front mount and bolt ons you should be at your goal power with the T25. get it tuned tho

i made 247whp & 245wtorque with 7-8psi(stock wastegate) using an AFCneo, t25 from sr. even got dyno chart to prove it!

what was your complete set up?

[240sxvaj]

450cc deatschwerk, 255lph walbro, nismo fpr type-B, z32 fuel filter, bottommount manifold (nobrand), sr hks hotpipe/ssqv combo, sr megan elbow, sr blitz3" dp, delete-cat, buddyclub spec2 exhaust, Greddy type-M FMIC, Z32 MAF, e-mance, AFCneo, etc.

I made 247whp before i installed Z32maf and e-mance.

Make sure you have wideband or dyno the car before running it into boost, plus the right spark plugs, gauges to monitor fuel and a knock light is a must. detect detonation if you dont know how it sounds like(like me).

One more thing, i recommend you getting bigger injectors around 450cc and bigger if you are planning to upgrade to t28 or t3/4. E-mance can tune it to run real good to save gas so no worries with having bigger injectors, just saves your motor.

wow cool! i will probably run 450's then. was your motor stock internally? if it is it sounds like my planned set up was pretty close to yours, and i might model mine after yours even more now, those are impressive numbers

yes, stock internals. But i am planning on going Arias .020/over piston and eagle rods, hopefully done by next month.

just to let you know this was done on a dynojet. i first got my car tuned on a dynodynamic(reads lower than other dyno) with a rough tune and running fuel ratio of 10's at 4K-6k rpm and still able to make 286 torque to the flywheel. the guy that first tuned my car doesnt know how to use an AFCneo. so the second dyno was on a dyno jet and this guy fixed everything which gave me 247whp maybe around 280+ base hp.

so u run those e-mance chips?? i was thinking about doing that myself but was just curious on how well they work.

I ran it for about 2 weeks, they are good and way better than safc. i ran an afcneo and after installing the e-mance there was a big difference in response. e-mance is good but just make sure you have a wideband. dont just drop in the ecu and assume you're good to go, that also goes with enthalpy and JWT ecu. every car is different.

[Tx-Sx-FS]

well i have access to a wideband so ok, but isnt safc good enough if dyno?

safc is good, but it doesnt have timing control and etc.. with ecu such as e-mance they cut the speed limit and set your redline for you, plus timing control for maximum power and the best gas mileage. only for around $150!

i been through 2 dyno shop to tune my afcneo and still wasnt satisfied. plus i was getting crapp mpg. save yourself the trouble.

I'm also not advertising for e-mance, he just told me to tell everyone of my great experience.

[Tyler]

anyone else have any ideas on what kinds of numbers i wil be making?

240sxvaj, i was just wondering how much u spent on your complete set up. I need to get some ballpark prices on what kind of a budget I can run with. Thank you

I kind of went all out on parts so it costed me around $2700 just parts. You can get your whole set-up for under $2000. if you custom some parts and buy some ebay parts then it would be pretty similar to my set-up just not name brand like mine.

i'm also getting my engine built so its going to cost me a grand total for labor and parts of $2400

Honestly i plan on making my car look really clean. after i get it all tuned right.

(sorry for bringing back an old thread)

240sxvaj, 1 more question for you. Are you running both the AFC neo and the e-Mance? or just the e-Mance? Also for injectors, do u think the sr 370cc will work fine for a t25?

I didnt use the afcneo even though it was still hooked up to my ecu, i set it to 0, because the tune was good enough. jason offered a fine tune if i send him a graph of my air/fuel ratio. honestly you dont really need the afcneo. I blew a piston ring so car is going through surgery "arias piston(.020" over), eagle rod, etc...." my fault though not the ecu, i didnt have a wideband...biggest mistake!

370cc is a common t25 set-up so it wouldnt hurt to run them, but i recommend you running bigger injectors if you plan on going bigger turbo/boost. safeR w/bigger injectors, saves you a lot of money and the ecu can be tuned for bigger injectors so you can save gas when normal driving.

Hey 240sxvaj could you post your T25 dyno I'd like to take a look at it, thanks.

the dyno tune was the first dyno from jerdevelopment in westminister which ran really rich making around 220whp on a dynodynamic, i did a second dyno tune on a dyno jet(osr in hesperia) which made 247whp241wtq since the second shop knew what they were doing.

On the very first video titled "dyno day" at .27-.28-.29 seconds listen to that noise (very distinct), is that detonation, my car makes that very same noise once in a while at most throttle tip in, I believe for me it accurs at 3k- mid 3k.

BTW do you have an actual dyno graph/chart

Thanks for sharing that BTW.

from what i remember there was a rattle coming from the long pipe that he stick in my tail pipe to read airfuel ratio. But there was a lot of detonation on this dyno. i didnt know much about detonation at the time but i later took it to osr and reggie redid my timing and got rid of detonation completely and gapped my sparks with better tune on my neo which gave me a whole lot more power compared to this first dyno. honestly i recommend reggie if you need a dyno tune.

the dyno chart is on this page just scroll down and you'll see it. btw this is the second dyno shop.

Im sure the sounds at ~.28 seconds in the video is no the wideband rattle, I have always wanted to record that distinct sound but you have captured it for me...lol...thanks........

That "dyno pull" was that on a stock ECU if so what was yoru base timing set to or did you have a rom tune?

Reggie, is that Andy's friend from Moval?

BTW im running the same setup but I have the Nistune program and Innovate LM-2 wideband.

[240sxvaj]

Yeah the first dyno shop was using stock ecu w/ afcneo to tune. timing was pretty close to stock(i dont recommend jerdevelopment), they told me it was okay at that timing which was B.S.

I'm thinking about it and i think it is detonation. well dont know much about reggie, but one of my buddy Riley cahill told me about him. riley goes out to drift buffet and use to drift w/sponsor black r33 gts-t skyline. i'm running emance which have timing control now, but my motor still in the shop, hopefully upgrade the turbo after i break-in the motor. still need to buy a wideband.

You live in fontana? how long have you been ka-t?

Oh yea definantly if you were on a stock ECU and running a base timing of 20* no doubt you were most likely detonating even at only 7psi on T25. I bet that sound at ~.28 seconds was when you were coming on to yoru peak torque.

Yea im in Fontana, been KA-T for about 5 months now....but im not new to turbo cars, I come from the FWD platform of the B13, B14, P10, P11 crowd.

I also had a B13 SR20DE 9.5:1 turbo T25 and that same exact sound occured when it started to detonate so teh KA24DE(T) sounds exactly the same as my SR20DE(T) did as well also that particular engine ran a stock ecu as well.

[240sxvaj]

thats kool i have a buddy in town that is also going ka-t, and met other guys on nico in socal that are ka-t. we should have a meet or track day at california speedway. but thats after i get the car done which might take a while.
