IHI VF35 turbo

3" miltek decat system with 5" cobra backbox

255lph walbro fuel pump

550cc sti pink injectors

sti top mount intercooler

3 port boost control solenoid

Depending on what your current mileage is it may well be that Duncan (Dynamix) is happy that's as far as he wants to take your bottom end BHP wise. I have to say though i would have expected a bit more torque but maybe there are reasons for it not making so much. How long did the remap take? Couple of hours?

Whichever TMIC you currently run will denote your BHP capability. If you have an STi TMIC that will be good for over 400bhp, if not the WRX intercooler should be OK for c.340bhp.

If you fit an FMIC you will have to get the map tweaked to run better with it. IMHO the VF35's limit is about 350 anyway so unlikely for now that it's worth bothering with an FMIC unless you're having problems with running a TMIC. At your current power level i doubt your TMIC is struggling and if it is try an STi intercooler if you;re not running one already.

I mapped a WRX with a little while back up in Newcastle with a very similar spec to yours but ran a TD05 16G instead of the VF35. That's making about 320bhp and 330ftlb torque. He runs an STi topmount and removed the TGV's in the inlet manifold.

I wasn't pushing the mapping as much as i could because my customer drives like a loony and demands a lot from the car so better be on the safe side. Anyway there's definately a bit more to be had with some more time spending on it. It took about a 6hrs to get it this far, another half day and it should be sweet!!

I'm a firm believer in mapping a car for more torque rather than power. It's easy to get the power top end but it's more involved to map for a torquey bottom end which is why it can take a little while. IMHO it's also safer as far as high mileage engines is concerned. If a job is worth doing though it's worth doing right and taking your time over it.

Do you map Subaru's only?

[ScoobieWRX]

Yes.

The same mapping tools i use for Subaru's can be used on EVO's as mapping wise they are both very similar but right now i've no interest in mapping them. There are tuners out there that do only EVO's and they are expert at what they do.

I'll stick to what i know and love.

That's a shame; will hopefully be geting a Apexi Power FC for the Celica and am starting to think about who could do the mapping. Oh well, keep up the good work! You sound like someone who won't give the car back until it's perfect! Awesome!!!

Thanks for the kind words.

That's exactly how i work. I know that if i'm happy with the work i've done my customer will be really chuffed with the end result.

If i were you i would be talking to a tuner like Prolex or Fensport. They are Toyota specialists and will know exactly how to map your Apexi to suit the mods you've done to your car.

Good luck with that.

Yeah I'm not far from Fensport, though I was under the impression they did Motec only. Got to get my Evo FMIC core fitted though. After new 'box oil and a wheel refurb it will be a little while!

Thanks for the thoughts , not previously heard of Prolex... Hmmm

Now yes, Ryan has been recommended several times! Does he just use your RR vixpy? Surrey ain't that far

He does indeed, in fact he is there tommorow, weds, thurs and maybe fri as well

I'm not that close to getting it done Gotta get new shocks, wheels refurbed, apexi pfc + turbo and front mount pipe kit before i can bring it to ya!

Thanks though! I'll eventually get down to you!

Stick with the STi TMIC. Good for 450+, without sacrificing throttle response.

Disagree, they really start to struggle over 400bhp

[ScoobieWRX]

I don't know anyone that managed to get a genuine 450bhp from an STi TMIC other than Andy Forest. That's not something that happens overnight and not something you can acheive with the average 2hr remap i seem to keep coming across so often.

Depends on the Car, My JDM 350bhp/350lbs would live with the same weight UK scoob with 400bhp, a on Track or road

I'm running a Licthfield twin scroll LM400 turbo that was running 415bhp comfortably of a TMIC. Although had to be mindfull of intercooler heat soak issues with a larger Turbo I have now removed the Induction kit because it went PSHHH all day long I am running the OEM induction and nearer 395BHP. BTW The litchfield Type 25 Cosworth ran 425bhp on a FMIC.

You "Generally" and vey much depening on your usage so benefits and loses do change to Mods and Usage. So my humble guide is

look at a an Induction kit on a 2.0ltr over 400bhp and 2.5ltr 430bhp
Look at a FMIC 2.0ltr 420bhp and 2.5ltr 450bhp

Agreed about the heatsoak for sure and 415-420 from the TMIC is very doable and pretty reasonable by any standards but 450 is much harder to do.

I've no idea if he did that on a cold day, covered the intercooler in dry ice, used Meth injection or what but 450 on the TMIC IMHO is pretty impressive, specially mounted where it is right by a red hot turbo.

I've often wondered if it could be made to work even better by mounting it as an FMIC. As a TMIC working right next to the turbo and as a factory part it's a pretty impressive and well made bit of kit however i don't know anyone that's done this.

I plan to do it at some stage to see just how much better the STi TMIC works as an FMIC.

Any thoughts on this and it would be purely an experiment?? Could it work as well as a proper FMIC?

[T5NYW]

Not sure using TMIC as a front mount if newage it is Much wider than a FMIC, so not much room

The TMIC with very short pipework gives good effeciency from 25mph to 120mph. but at higher speeds, it's effeciency can drop off due to some air missing Scoop. downs heat soak from turbo at very low speeds

The FMIC has a greater surface area so effecient from 20mph to 180+ mph down side is length of pipework and lag

IMHO
