Tom this is a very well thought out built and really quality built , but is it really safe running over 30psi on a stock turbo . I'm asking you this because I need a sd/3port tune . Just seems it would greatly reduce the life of the turbo and exhaust manifold from the high EGT.

 

absolutely. the intake manifold and exhaust manifold and o2 dump are responsible for a lot of the gains. not sure how much the duct helps on cool days.. that kind of mod shines when you're in 90F+ heat and being pounded by heat.

ya you can run over 30psi.. mitsubishi turbos are very strong, but running 32psi on 93 is not something you wanna keep doing. we wanted to see what we could max the car out to on 93 and this was the result.

its since dialed down to about 29psi now. owners in the process of putting back OEM intake mani and exhaust mani so i can retune it and show the overlay of the other mods if there's interest in it..

 

Lookin good

 

Is this a USDM RS or JDM RS? Do you guys get the proper 9RS turbos with TiAl turbine and Mag alloy compressor (571) or just the vanilla non RS (580) turbos?

What are the turbo outlet temps like at almost 30psi @ 6K?

 

i think its a US rs

 

The turbo is the same across all 9's here in the US


Thanks for the response Tom, I would be very interested in seeing how much of a monster this one is even with stock manifolds. I got a feeling his is a freak

 

very interesting build. not something you see often. nobody matches those parts to a stock turbo build.

very impressive results!

 

It goes to show that those parts do not create "lag" like almost everyone claims on this site!

 

heres a really cool comparison between this car and another evo 9 stock turbo with 93 and meth that went 120mph traps.. i dont care about the traps as much as i care about the torque curve comparisons though and boost curve.

i guess this does show that bigger intake mani and tubular mani really doesnt hurt the low/mid range as much as we think it does.. (or atleast i thought)

id honestly expect more difference here.. id expect mid range losses but there isnt much.. maybe a 14tq/hp loss at best.

so once we put this car back on stock intake mani and stock exhaust mani i will show you guys the comparison overlays.. this should be interesting!

but heres this comparison against another car i did on 93 + meth for now.



whats even more interesting is the amount of boost i was able to run with no knock.

so were getting practically race gas results from straight 93 from just a few simple bolt ons it seems.

im really hesitant to putting a f1i on my personal evo.. because im so obsessed with torque curve and power
under the curve.. but this kind of makes me want to at least find out what happens.

 

I had similar bolt on but with fp green with my old setup.. I couldn't get pass 27psi with 94 octance or else it will knock.. with DBB red/MAP exshaust manifold/muse 02 dump and the magic from Tom, I hope I can get better result than what I had!

 

actually I do think the exhaust manifold and F1 are hurting torque from 3000-4000. what I though was impressive was reaching over 425whp on 93 with stock turbo. that is hard to do in florida.

if I were looking to make 425whp I would choose my parts differently. here is my hta green at 21psi on 2.3 liter. note how late pull was started and how fast it builds torque. and the tune is no where near done. I have 5 degrees pulled from spool area cause the throttle response was actually too jumpy on the street. made it hard to drive smoothly.

 

Nice job on the tune Tom! Glad the ToxicFab manifold helped him make some nice power on 93! I like his little DIY cold air box, I will be doing the same once I delete all my ACD stuff. Do you know if the finished product (wrapped in gold foil) is made out of aluminum or SST??

 

Tom when you say no knock, do you mean never any at all? I didnt think none was possible. How much timing you running at peak torque and at say 6.5K?

 

Yea I also would like to build a similar intake box setup. A how to thread describing how to make that intake box would be awesome.

What kind of fuel pump was used?

 

no doubt im sure it effects it some yes, but doesnt seem to be enough to bother me based on the 2 graphs i overlayed there.. but and its a big but.. it may vary way more once we do testing back to back on the same car itself with and without the parts. so ill for sure share how it responds after we remove the parts.

i just bought all his parts pretty much for my car lol. the f1i should open my car up a lot since its a 2.3 and the rest of the parts shouldn't really hurt me to bad if they do ill remove and put what i have back on now.. its worth seeing what happens though.

nice graph you got there though.. the green and 2.3 is a wicked street combo.

we had knock during the tune sure, but once i finalized everything there is no knock anywhere.. there's around or over 10deg uptop. bit more on the 29psi tune though. with ecu boost we can push it hard in 3rd gear then drop boost in 4th so you have clean 4th pulls also.. thats one major plus with ecu boost.. typically 4th induces knock when you tune 3rd aggressive.. but with the luxury to alter boost per gear we can knock it down in 4th.. car pulls clean 1-2-3-4, etc no knock. if any maybe 1 count, but timing isn't effected, aka just non detonation noise. load doesnt vary enough from 3rd to 4th to taper timing left to right to control ignition advance, therefore boost per gear is super super nice.

I believe modified walbro 255.

Thanks BJ. The ToxicFab is mine now lol.. i just bought all his parts for my car

I asked him and he said he used DEI reflect a gold.
