im collecting parts to upgrade my 05 blobeye to about 360bhp heres what i got so far

garret roller bearing turbo rated to 425bhp

aps tmic

aps cold air induction kit

pink 550cc injectors

i know i need sti scoop and tray, and 3" sports kat system (anyone got one for sale)

but do i need any other ungraded sensors like maf and other things like that coz i know naff all

Fuel pump and remap

I thinks thats all, however if you only want 360 bhp from a 425 bhp turbo, your not going to be mapping it to its potential and may be a bit laggy to drive.

just contact a mapper with your requirements and take their advice probably easier to invest in changing car to sti though

newbee

i was told 360bhp was about as big as you can go in the hp stakes safely to avoid being more prown to blowing the engine and you would be unluky even though it not heard of for it to let go at that

3 port boost solenoid would be a handy mod.

my intention was not to do anything with it,it already has ppp on it but after a month of ownership ive got the scooby bug and you can never have enough

Billet

no, your engine will be fine, im saying i think that your turbo may be too big for your power goal, and the drivability of the car may be compromised. Maybe a vf35 instead or if you want a very quick road car then a TD05 18G, however the TD05 will be more likely to kill your gearbox than a vf35

newbee

iTrader: (8)

name says it all really just been offered one of those but what does it do

newbee

iTrader: (8)

the aps is supposed to handle upto 400hp its as big as you can squeeze in without going front mounted so i could push it up to that if the other mods would let it if u think that would inprove driveability

KAS35RSTI

iTrader: (73)

It will control boost better than your current 2 port one. So less boost spike etc. Would be useful as you do have a pretty large blower.

KAS35RSTI

iTrader: (73)

What he means is the bigger turbo is not going to spool as quick as a VF35 or 18G etc. Basically you will make power later regardless of how much power the turbo can take.

The others have amply covered the turbo issue. Buying one that is bigger than necessary compromises the driveability of the car - slower than ideal throttle response, slower than ideal spool. If you haven't actually bought this turbo yet I would get something different in your shoes.

Also, have you actually bought/paid for the APS bits? If not, you may well want to save your money. Standard induction tract is fine at this level, while the obvious (and more cost-effective) intercooler would have been an STi one.

All said on the assumption that your "05 blob" is a WRX - which you haven't actually specifically said.

There's no need to change sensors, although as has already been said, a three port boost control solenoid is worthwhile as it gives better, more granular boost control, which is worth having, and especially so if you're going to stick with the inappropriately sized turbo.

Split, im also guessing its a wrx and not an STI, the mention of 550cc injectors, sti scoop and tray pointed me that way, in which case sell the car, buy an STI, its going to be cheaper to start with and in the long run.

what BHP will the std injectors run out of puff?

s70rjw

iTrader: (2)

De cat up pipe to help spool up. The Classic up pipe and STI ones are catless and are a direct fit I'm told

BoozyDave

iTrader: (8)

yep, get an sti up pipe, you'll get one for about £30

dynamix

iTrader: (3)

wrx injectors will run out at about 310bhp (give or take)

550's will get to 400 ish.


The APS top mount is very good and easily capable of handling that power and more although a good fmic will net more power ultimately.

One good thing about using a slightly bigger turbo is that your gearbox will be under less strain than with an uber spooly turbo so may well cope with the higher power better. As it is ball bearing cored it should respond quickly so that is a good thing.

What turbo is it?

BoozyDave

iTrader: (8)

i've got a decat uppipe and 3'' decat downpipe, vf35 and ported headers

what size injectors? yellow 440's or pink 550's?

what size are std?

be needing a remap soon too dunk....

dynamix

iTrader: (3)

Yours are light blue 420cc Dave.

No probs mate - gimme a shout and I will let you know when I am yorkshire bound

newbee

iTrader: (8)

its a AET VT272-64 Garrett Ball Bearing Turbo (Zen Performance Spec) which I have been informed is a GT3071-64 standard fit turbo rated at 425bhp

thats off the advert i havent gained uber knowlege over night

and thanks for all the other peoples input

newbee

iTrader: (8)

would this make it fail an mot on emissions would you have to take it off evey year for mot

A turbo like that is good on an STI, not good on a wrx, these engines dont seem to like much above 350bhp without throwing something out of the pram (or through the block), if I were you, sell the car, buy an STI and then you have a good starting platform (plus a better all round car), it will cost you considerably less to modify and you will have a better handling car thrown in
A wrx isnt a good starting point if you want over 350bhp, it just gets far too expensive, gearbox, clutch, brakes, injectors, turbo, top mount/front mount, rear diff to go with that gearbox (note a PPG new build 5 speed gearbox is like 5.5k and they still retain the standard 5th gear cog which seems to cause all sorts of problems on high powered scoobs).

Rethink what you want, go look for what you will get for your wrx, look at the prices of the STI's, look at the cost of all your mods and you will see how much cheaper it is to start with an STI in the first place

If you do decide you want to fit that, it will need to be held back to such a massive extent to stop it blowing the box that it will feel lifeless.

Good turbo but needs to be set free.

Would need 650cc injectors and a few other mods to be allowed to perform it's best.

newbee

iTrader: (8)

does the wrx have and different gear box to an sti then

mervil

iTrader: (5)

Yes, the WRX is a 5 speed and the STi is a 6 speeder and a hell of a lot stronger!!

An STi is a better base car and will get you better results!!

BoozyDave

iTrader: (8)

if you want over 350bhp, i'd start with an sti

better engine, gear box, suspension, brembo brakes, adjustable centre diff, thicker anti roll bars

other point, you are starting with 225bhp and wanting to increase power by 60%. how long before something fails?
wrx's can get to 330bhp before prob's start, sti's 450bhp is achievable

If you go for an STI, be sure to go JDM
