Im compiling a shopping list before having the bug remapped. Its completely standard at the mo, but have a quandary....

should i change my WRX TMIC for a STI TMIC or should i get a FMIC?

I know the STI TMIC's sell for about £160 - £180, and the FMIC's range from £200+

What are the pros and cos of running either, and what you would you choose given the choice ?

If you would say FMIC, what would be your weapon of choice? (please be kind in my bank)

Thanks

Shaun

 

depends on what power you are aiming for...sti tmic is good for 400hp

 

+1

 

Looking for around the 350 ish mark when all is done. but I want to get as much as i can (except a new turbo) before it has the initial map.

with the STI TMIC will i have to butcher an STI under tray to adapt it to the standard WRX scoop?

 

If your car still has std internals, & its a wrx the the gearbox will limit your power before your engine, then the sti topmount, Andy Forrest was running 460bhp on an sti topmount.
With a topmount you will get heat soak from the engine, you will not get this with a frontmount.

 

Yeah, still running standard internals unfortunately. What kind of power would I be restricted to with the standard gearbox?

Sorry for the noob Q but what is heat soak on the intercooler and what effect doesn't it have ?

 

standard turbo stay intercooler as is, upgrade turbo go front mount

 

FMIC look's cool makes the car sound better

 

This is the path I followed.

 

Im glad you understood that fella, im still trying to unscramble his message

 

fmic do look good, but id get an sti tmic for the power levels you are wanting.....

 

I have a wrx bug running 350 std internals with a vf34 but have changed to a 6 speed but I did not break the 5 and it run over 300 for three years, I have just gone fmic from a big tmic and when remapped it spools a little bit slower but I got 7 hp more 20 ftbs more mid range .

 

What about adapting the STI TMIC to go on a WRX, will there be and mod to the scoop under tray for it to fit

 

i just put a sti top mount on a wrx in the dark 2night in about 15mins

 

hahah,

the standard wrx turbo (td04) is a bit like an asmatic blowing into the engine, makes changing to a front mount not worth it.

as soon as you upgrade the turbo then front mount is the way to go.

While other top mounts, such as the sti, will make 400bhp with the right supporting mods, after about 300 they start to be the restriction and you will see a better result from a front mount with inlet temps, they also dont suffer from heatsoak when stuck in traffic and give the mapper a bit more to play with.

 

i would spend £150 on exchanging you td04 for a td05

 

Is that all it would cost to go from Td04 to Td05... what are the benefits of that turbo over the standard WRX one.

 

Cheers for explaining that fella

 

just got quoted that from ken at scooby split for a mate with a wrx tonight and thats a recond td05

 

What is the main difference with the Td05 turbo unit fella?

 

You'll probably have a cat in your up pipe too. i am selling an STI one with no cat in, can email you pics if interested. Will be selling for around £40.

 

well i went out in 2 wrx's today one with td04 and one with td05 (both felt slow getting out of mine lol) and the td05 was noticeable quicker but the turbo come in a bit later

 

Thats one thing i do already have, but will wait until just before the remap to get it fitted.

Please, guys keep an eye out for either a STI TMIC or a decent FMIC..let me know if you spot any.

Cheers

 

I'll be selling my 2003 sti top mount in a couple of weeks pal.

 

Hi Bud,

Heat soak is when the heat from the engine & hot turbo warms the intercooler when a topmount, with the front mount you will not get this.
this only happens when the car is stood after a run.
looking at what you are wanting to do I would look at an sti top mount TDO5 18g turbo that will get you about 340 to 350ish then when the gearbox goes save for a 6 speed.

This is what I am running with a top mount, I get very little lag and its a GT3076 and as you can see from picture, I am running a Hyperflow topmount, I do get heat soak though.


Front mounts do look good and no heat soak,
De cat the zorst will help reduce the Lag and give better throttle.

Good look with the mods and get your name down for the overtime at work

Bez

 

If i upgrade my 52 wrx bug to a td05 will I need to re map it straight away ?

 

Hi Bez,

What undertray are you running with that intercooler? With the strut brace there how are you making a seal around the intercooler for best cooling effect?

Thanks

Dan

 

yes

o and also, dare anyone mention the cost of a hyperflow top mount? lol

 

I'm on the list for a Japspeed fmic so will look out for a td05 and get it all mapped up then ! Cheers

 

bear in mind td05 isn't your only option, it can be got cheap but doesn't always get best results. vf35, vf34 or even sc series is also similar. It all depends on budget in reality.
