Fisher Price - My First Turbo....

[Kai]

Thats kinda what it feels like anyway - i got me a nice big red '91 Turbo now, picking it up soon and it's already got substantial suspension/braking mods done to it (TEIN coilovers, Fensport Cross Drilled Front Discs, Pagid Fast Road Pads), thing is the engine is almost totally standard.

The exhaust has been upgraded with a Blitz NUR Spec and theres no cat fitted. The intake is unmodified though - standard airbox with K&N panel filter.

I wouldnt have thought the intake side would have mattered too much seeing as it's forced induction anyway. The car also came with an HKS EVC Boost Controller, APEXi SAFC (dunno if it's I or II) and a turbo timer (unknown).

Fitting all these things is all well and good, but would i be okay to run 10psi on with just the intake and exhaust as they are? If so - what kinda HP would i be making at the crank and wheels? Nothing pinpoint accurate, just ballpark figure needed.

Well, i'll be having more questions from this point on.....guess i need to get used to owning a tubbie

Hey Bud!

What downpipe is on that car? If all little known problems are up to snuff on the motor and it is in a good state of tune then you are more than safe to run 10psi. You should see 275ish hp.

 

[Mr.PFloyd]

whats happening to the black car?

:ttiwwp:

Good to hear you went boosted

 

[Kai]

Black car was part exchanged against this one. Pics i'll d a little later on.

Downpipe? I cant be certain, it MIGHT be the standard one, or it might be a blitz one - whole systems here tend to be turbo back as we dont have catalytic converters.

275bhp, is that crank or wheel hp?

 

[Big Wang Bandit]

Wheel I believe. Go take a picture of the back side of your turbo by the firewall and we can tell you if it has a downpipe!

 

[Kai]

I will do, but not now - its 3:57am!

So yes, 10psi, 275 crank hp or wheel?

 

[Supracentral]

I will do, but not now - its 3:57am!

You're awake, I'll bet your camera has a flash...

Kai fails at the "being a hardcore Supra nut"...

 

[Kai]

My camera is a Sony Ericsson K750i Phone with a crappy LED flash

And i'm wearing nothing but my pants, cause i'm in bed

Aaah wireless keyboards ftw

I'll become a hardcore supra nut when its a) not so damn cold b) i have clothes on!

 

[isnms]

I haven't read the thread. I just liked your title :bigthumb:

 

[Kai]

Hehe well i thought it appropriate - mainly cause its big, red and shiny all over and i've never driven or been in a tubbie before... :biglaugh:

 

[Kai]

Oh, i also need to get an O2 sensor. Rather than getting one from Toyota, someone on the UK boards gave me this url:

Which one do i need? I know the N/A is a single wire one - is it the same for the tubbies?

 

[isnms]

Check with MDCmotorsports

Oops, last post in that thread says 'out of stock'. But that was May last year. I'd check with him anyway.

 

[Kai]

Buying one from the GB works out more expensive than buying one here

I will however, ask him if any of those universals are any good.

 

[Kai]

Aaah - its a 3-wire one, Turbo O2's are heated, right?

 

[isnms]

Yes it's a three wire heated sensor.

Sorry, I didn't notice at first you're in the UK. If he has them, he would probably ship there.

 

[Kai]

£21.60 isnt a bad price for one i suppose....although i think i'm going to need a throttle position sensor too :S

 

[TurboWarrior]

fyi those mdc sensors dont fit in some aftermarket downpipes. I had to file down the lip for an hour that the mdc one has that the toyota one doesn't have right under the flange. Luckily the sensor still worked after.

 

[Kai]

I hadnt thought about that...i'll take the other one out and see if its a stock denso part, or an aftermarket OEM one

 

[TurboWarrior]

Most aftermarket ones are thread in and have an adaptor or another bung welded on to accept it. if its a bolt in one chances are its toyota. The mdc one is Denso and bolts in like stock but is shorter than the factory one for the supra, which doesn't matter.
