turbo upgrade- what gains to expect
Hey Guys
I just removed my engine again! and had a good look at my turbo, it is a VF10, great turbo it hits full boost (14psi) at under 3000rpm but doesn't
pull that hard. only made 140kw@ wheels.
I want to make around the 200kw @ wheels. but not have a lag monster as it is still a street car.
Is it possible to do this with just a turbo upgrade? obviously injectors will be upgraded, my cooler and exhaust are up to the job. (air intake hits a
max of 40 degrees)
if so what turbo will I need (under $1000) I have a friend that will reco / hi-flow it for me on the cheap so that's no problem. Would a hi-flowed
TD05 be up to the job? any other ideas?

Im sitting on about 14psi, cant remember/quote intake temps but I know they were running well when sitting on dyno for ages. The way my cooling is
setup, I know the air/water i/c is always ambient temp or there abouts even sitting in the hot engine bay (very little heat soak).
I dont think its laggy, some might, I suppose what your used to but it pulls very hard from just under 3k all the way to redline.

Your little vf10 is off the Auto. I run a vf24 which you can get for about $650. It is a fast spooling ball bearing turbo. Ideally you would get a
vf34, which spools like my 24 but flows like t5. I have a tdo5h ($350)I am about to put on for a comparison, so it will be interesting to see. The
bigger turbo wont increase air temps its more boost related. You want to keep them low so you can wind up psi and advance that timing.....all adds up
to kw.

VF34 sounds good to me but will it bolt straight on to my stock exhaust manifold and to my dump pipe?
i under stand ill need a new banjo bolt cause the BB turbos requires less oil (me thinks) thats easy.
how much should i expect to pay for one?
obviously theres no point in hi flowing my baby turbo is there?
and the only other mod i will need is a injector upgrade corret? and re tune of the wolf?

As far as I am aware, it will bolt straight on with no mods. My old VF28 was a straight fit.
Retune yes to take advantage of the new turbo but at this point still no need for injector increase. Just make sure your fuel pump is working well and
the fuel reg is up to it all, but these should show there weakness with the dyno tune.

So the debate is down to a TD05 or VF24 or VF34,
ive found these:
http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&rd=1&item=1802130630...
http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&rd=1&item=1901962062...
and the TD05 just got sold for $250 on RS Lib Club.
what would you guys estimate my power increase to be?
would i need to get it hi flowed to make a serious increase in power?
would i still need to get rexy heads or head work to make around my target of 200RW KW?

Firstly I would be hesitant of buying a $250 TD05 from RS Club. Dont scrounge on the $$$ for your turbo.
Im not having a go at you as Im always keen on what can make more power, but read the posts carefully. Im making 181.9 kw atw to be precise with a
safe tune and stock TD05, what more do you want? Is everything else around your motor going to take your desired 200kw?
With my limited knowledge but years of crapping on in forums, everyone seems to think VF's are the ants pants. Again, Im running a TD05, so is or was
JVL with 300+HP (albeit modified). From memory Jak Rizzo is at about 150kw atw with the lesser TD04. My last little praise for the TD05, correct me if
Im wrong but havent Mitsubishi been running a TD05 in all the EVO Lancers up until the last model or two?
Let the tune tell you if your running out of juice and then look at pump and inj options. My 2 cents worth.
Either way, go the Fasty

I found a AVO400S for about a grand, think ill slap that sucker on, only problem is I need a new intake manifold to run the turbo under neath instead
of the 90 degree bend.
Does anyone no what year the higher manifold started? and if it will bolt onto my engine?
and can I but just the manifold and then run my throttle body and injectors on it?

TD05H is the go, not sure what the "L" is, tjhere is also the TD05-16G6 if you want to be confused more.

The RS Heads you guys think are no good?
i was told that subaru in the early 90's would replace RS heads for WRX heads under warranty because they had noisey lifters. Now i know my engine is
100% japspec RS, how do i know if the heads are allready changed? (cause they are silent)
I still have my old 96 quad cam non turbo motor siting around, should i swap head with these?

I think JVL made this comment due to you thinking of using the AVO turbo. You would need extra fuel in the tune as well .
I think 200kw atw is achievable from your stock engine but you will need some small mods to the (say it again) TD05H as per JVL's suggestions and
looking at the injectors and fuel pump/reg. From what I have heard, good exhaust flow will be a big key and if this is done then the stock Suby
inj/pump and reg should still be good. Mine isnt at its limits at 182kw.
What you think John?

But you of all People on here know shit JLV !
The heads fail 100% of the time after doing some ks !The retaining clips all so fall off , they are piss poor & FAIL !
RS cams do not get any peak power , porting these are a total was of coin .
Yes the closed deck non turbo motor is the way to go .funny thing many of these motor subaru contracted out to supply other motor companys .I removed
two of these from a JDM izusu wagon on the cover was subaru ej20 quad cam 2ltr .I still have one of these motors running 1994 wrx big bucket heads
forged pistions & a VF28 turbo
Get a set of heads like GTB > AKA V3 STI ( over $1000.00 ) if you can find them in good cond
These days it is worth to build a 2.5 ltr motor for the same cost of parts as a 2ltr .
Follow sam Mean RS build on the RS forum
Do away with you rs heads they are not worth the cost of a set of subaru head gaskets !look out for a wrx motor that has droped a pistion skirt &
you on your way for a good set of heads .

say you motor came into Australia & subaru of australia replaced the heads with wrx units subaru would of placed some pink paint on the heads
.Simon has a motor like this & I have serviced many over the years .
RS heads have two bolt holes to hold the coil packs in place + the rocker cover has grooves top & bottom
on removal of the cover you will see a small rocker .
WRX heads have one bolt hole to hold the coils in place grooves to the top of the rocker cover & smooth in the lower area
on removal of the cover you will see under the cam a disk ( bucket ) about the od of a 20 cent peice .
I hope this helps

Having sqiz on certain forums such as RS Liberty Club, it would seem that most are in favour of changing to WRX heads. I know nothing of the specs for
each unit but Neil has just reminded me that I have WRX heads because of the 1 bolt. Have heard the cam in the RS is like the Forrester cam and not as
radical.

The RS Heads you guys think are no good?
i was told that subaru in the early 90's would replace RS heads for WRX heads under warranty because they had noisey lifters. Now i know my engine is
100% japspec RS, how do i know if the heads are allready changed? (cause they are silent)
I still have my old 96 quad cam non turbo motor siting around, should i swap head with these?

Wat a load of hot C**K.....theres nothin wrong with RS heads.......
|
But you of all People on here know shit JLV !
The heads fail 100% of the time after doing some ks !The retaining clips all so fall off , they are piss poor & FAIL !
RS cams do not get any peak power , porting these are a total was of coin .
Yes the closed deck non turbo motor is the way to go .funny thing many of these motor subaru contracted out to supply other motor companys .I removed
two of these from a JDM izusu wagon on the cover was subaru ej20 quad cam 2ltr .I still have one of these motors running 1994 wrx big bucket heads
forged pistions & a VF28 turbo
Get a set of heads like GTB > AKA V3 STI ( over $1000.00 ) if you can find them in good cond
These days it is worth to build a 2.5 ltr motor for the same cost of parts as a 2ltr .
Follow sam Mean RS build on the RS forum
Do away with you rs heads they are not worth the cost of a set of subaru head gaskets !look out for a wrx motor that has droped a pistion skirt &
you on your way for a good set of heads .

Are you for real?...its JVL

Is porting these RS heads are a waste of time using bigger cams.....etc
