hi everyone im new to this site so sorry if this is in the wrong place, im buying a sti blobeye soon and im looking to push it to 400bhp, this is my shopping list and need advice on if anything else needs to be added or changed, i also have a number of mods like brakes and strut braces but dont need advice on them.

3" Decat system

Short Ram Air Induction Kit

Fifteen Row Oil Cooler and Relocation Kit

Front Mount Intercooler Kit

Universal Oil Catch Tank

Cosworth High Performance Kevlar Timing Belt

Exedy Stage 1 Organic Clutch Kit

750cc Top feed injectors

Walbro Fuel 255ltr FSE

NGK IRIDIUM SPARK PLUGS HEAT #7

FP Green Turbo

Remap

From tht list seems like uve got everything covered buddy jst ensure its mapped by a reputable mapper..

You dont need all that on the list, You can run 400 on standard airbox and intercooler(Personal chioce), Plugs NGK Platinum PRF7B would do, 650cc injectors are fine for 400bhp, Wouldnt need an oil cooler(but if tracking it i`d reccomend it), One thing that is not on there are some form of gauge to read temps/fueling etc....

sparky2008

i'm sure i read somewhere that with the tmic when your pushing nearly 400bhp as the engine temps go up it warms the air on it because its so close and ya loose power so read its best to go for a fmic but thats why im on here to ask really because people on here will have more knowledge. anyone recommend any turbos other than the one i have listed?

The Pink Ninja

iTrader: (23)

Yep the inlet temps do increase with the top mount but i`ve know a few that are 400+ on the standard top mount and airbox, Now granted you will see lower temps and more than likely a bit more torque with a front mount thats why i said personal choice as its borderline with 400, If you had said 450 it would be front mount for definite, Best bet is to speak to the mappers as they would be able to advise you best, Regarding turbos there are plenty of other choices than an FP Green, Speak to Scooby Clinic who do the SC series and Lateral Performance who do the MD series.

wouldnt recommend an FP green... just dont work well on a subaru

Looking at the list the short ram induction kit could cause issues with the MAF sensor due to turbulent airflow. I found this when I wanted to get the OE ecu OS mapped, as I normally run a GEMS ECU which uses a MAP sensor instead. Going for a CAIK that relocates the filter to the inside the wing should solve this. The FP Green turbo does work well on my Bugeye Scooby and pushes out a nice 440 bhp on the Clinic's rollers. The one thing missing is an adjustable Fuel Pressure Regulator instead of the OE item get a decent one such as Aeromotive not a cheapy of Fleabay.

My Spec is;
F P Green Turbo
APS Hard inlet pipe
APS parallel fuel system
Yellow injectors (740cc I think)
APS 3.5" De-cat
Front mount intercooler
A big K&N filter
Aeromotive FPR
I did get a oil cooler fitted as I thought it was the right thing to do I am going to look at blanking it as the oil does not get over 80 C unless I kick it for a long time. Had it fitted when the cambelt was replaced so was only £15 extra on labour.
GEMS ECU
Uprated fuel pump from Lateral. I do have a Bosch 044 to fit at some point.

That is on my 51 plate bugeye with standard internals and as mentioned pulled 440bhp oin the clinics rollers with 104k miles on the clock.

thanks for the info guys, i think im gonna change a few mods but if 360ste says he had 440bhp from that turbo then i think i will sick with it

If you have it already the yes.

I thought it was a list to buy, hence the suggestion.

sparky2008

i mean stick with it on the list lol unless someone recommends a cheaper model that does just as good

Now if it were me, I'd be taking the advice of a REPUTABLE and RESPECTED mapper like JGM........

There are plenty of turbos out there that work as well, or better.

Agreed on FP Green,not the best turbo choice


Jura

Agreed, just because a turbo can make 450, doesnt mean it will be a nice usable 450!

A spooly 350 will be ALOT more fun and real world quicker than a laggy 450! If your chasing numbers then fair play to you, but its more money for less real world guts at the end of it all. Personally i dont think you can go wrong with the scoobyclinic billets or the right MD321.

Also, 3" decat isnt required until you get to 480+ ...... keeping it smaller will drop your peak torque and make a much nicer raspyer noise.

Most important thing is the ecu choice and who you get to map it .... east anglia ..... Simon at JGM is definately your best bet.

sparky2008

ok so after doing some more research i think the turbo im gonna go for will be sc billet turbo, i read a recommendation about the fp green turbo thats why i chose it but after so many people saying about the sc turbos then i think i will go with one of them, but if i decided i wanted to push abit more than 400bhp then what sc turbo would everyone recommend? i was told as the cars a sti 2004 that the standard ecu will be remappable and be just as good as the ecutek ecu and be able to have all the features of a ecutek, also i was told a 3" turbo back system is a must have for anything 350bhp+??

ECU Features include:

Speed Density conversion
Dual Fuel/Ignition/Boost maps
Per gear boost control
Flash CEL on Knock
Eliminate 1.7bar boost control/fuelcut limit
Use any aftermarket MAP sensor
GpN Antilag
Launch Control
Full Throttle Gearchange (aka FFS, NLTS)

Hi there

Personally I wouldn't choose the FP Green just due some making numbers and some nowhere near claiming numbers,second bits is reliability of those turbo(they're in some cases too fragile )

If you will be going above 400bhp,I would choose like SC42(those turbo making nice numbers and SC selling them for good price) or MD321T Billet(we are made on MD321T 452bhp on V-power and 490bhp on 20% meth)

Yes your ECU is mappable with right mapping,should be there no limitation and some nice features too

Features of EcuTek not sure,they're don't have more features as Open source CarBerry ROM

Syvecs I would choose everytime and everyday


Jura

sparky2008

the company i found use Carberry ROM for the ecu which offer OpenSource mapping.
ok so for now i might just use the standard turbo, injectors and take it too 330-350bhp until im ready to go the next step, what induction kit do people recommend to use with the fmic? i know the standard one and tmic are ok for this sorta bhp but as i plan on going higher in the long run there what i wana add in the beginning

SC42 would be spot on for 400bhp.

"i was told a 3" turbo back system is a must have for anything 350bhp+??"

Not true, im easily getting 440/440 through a catless 2.5" with more to give ..... big exhausts for more power is a myth! Bigger than you need usually has a detrimental effect on torque (more so on an NA car granted).... and as people are starting to cotton onto, torque is the new power! :-)

sparky2008

what system do you have or do you just have the catless pipes and standard back box?

The Pink Ninja

iTrader: (23)

If yours has a Prodrive exhaust ststem that will be why you got told to change it as the silencer become restrictive at around the 350bhp mark

Mine's running an effortless 400/400 on a TSL group N decat, tubular headers and one of Harvey's trick up-pipes.

It spools to 1 bar at under 3000rpm.

Bob (Rawle) kept the boost to 1.5 bar as it has the standard UK heads.

360ste

iTrader: (1)

That is what I did, I spoke to my mapper ,not JGM, who suggested the FP Green from his experience this was 3 years ago when it was obvious that the OE turbo was dying. Every mapper has their prefered options so deffo speak to the mapper you choose to use and work with them.

my FP green that cost me £170 off ebay works very well....


But would swap it out for an SC42 if pushed.

Remove the inline oil filter from the banjo bolt on the oil intake pipe if you use the fp turbo.

im running a full 3" decat system and running 420ish so are people saying if I had a full 2.5 system id be better off? ?

nyscooby

iTrader: (12)

no difference... but you can use 2.5" ok.

Jolly Green Monster

iTrader: (4)

big exhausts for more power is a myth as in you dont need a 5inch.. but you would see benefit with a 3inch over a 2.5inch at mid 400bhp...

nyscooby

iTrader: (12)

what benefit? (no sarcasm intended)

sparky2008

has anyone tried one of them cheap turbo imports on ebay? my mate had one on his skyline and swore by it but to me if its that cheap then surly it wouldnt last that long? i see one from the uk which had warranty but a garage has to install it to keep the warranty

jura11

iTrader: (7)

Not sure if I would go down the route of the cheap eBay turbo..

Its too much risk in this involved,some people have good experience with them(mainly over Nasioc),some have bad experience,just due they're not making nowhere near numbers or they just explode etc.

If your friend using on Skyline cheap eBay turbo,he making claiming numbers etc.

Reliabilty of those turbo is sometimes hit and miss and due this I would chose wisely there...

Good luck there.

Jura

sparky2008

yeah i wouldn't personally go for one of them, was just wondering if anyone else had taken the risk. personally i don't see the point in buying a decent motor and putting cheap parts on it. if ya gonna do it then do it right.

I have seen a few really good ones and a fair few more not really good ones. Including seizing within 80miles.
