Just interested in what you guys think the power of my car should be judging by others with similar mods. Also,what would be an expected 1/4 mile time ?

'96 Impreza WRX
Rebuilt engine by Api with '05 wrx pistons
Apexi PowerFC Ecu,commander and boost control-Mapped by Paul@Zen-Performance
550cc injectors
Walbro 255 fuel pump
Fuel reg set at 3 bar
Hybrid front mount intercooler
TD05-FE running 1.4 bar
Ceramic coated Gen II spec headers
Hayward&Scott full exhaust(heat wrapped)
Lightened and balanced flywheel
Exedy organic clutch
Rebuilt STi-5 Type-r gearbox
Different diffs but cant remember what they are !!!

The previous owner told me the car should be 340bhp/ 320lb/ft but never had it dyno'd with all the mods,ive been told it might be more so wondered what you guys think.

Also,ive seen a TDO5 20g turbo for sale.Will this fit straight on ? I know ill need a remap,how much power could I expect with this turbo ?

 

if your car is pushing out 340bhp then somewhere around the 13.1 to 12.8 sec. Terminals of about 100mph to 110mph. It is quite a hard question to answer.

I know my car was producing 294bhp ATH and managed a 13.2 @ 103mph. depends on a lot of different factor's to be honest. Get to the Pod and post up you times.

Will be taking it to the pod sometime this year. My E36 M3 ran a 13.6 1/4 and I would hope that this would be quicker.

 

I would of thought that a Td05 would need to make more than 1.4bar to make 340bhp.

The limiting factor would be your heads and cams, doubt that you'd make much more power with a 20g than you would with you turbo.

 

Im running pretty much same spec as you but with bigger turbo. At the same boost 1.4 and I managed a 12.2 at 113 yesterday at santa pod

 

Now thats quick !!

What turbo are you running ?

 

Standard position Gt30.

 

So,will a TD05 20g give me any benefit over what I already have ?

 

Im not really an expert but if yours is a standard tdo5 then yes you will notice a decent gain from the 20g. If you just want a decent 1/4mile time then lag wont be too much of an issue.

Mine is pretty laggy but you dont notice on the 1/4mile.

 

Mine isnt laggy at all at the moment,picks up really well.

Will the 20g fit straight on,I have a front mount ?

 

Yeah should be straight swap for yours

 

Might go for it then and see how it goes

 

Anyone know how strong my engine would be with a view to fitting this TD05 20g ? Its a '96 wrx engine rebuilt by Api about 9000 miles ago with '05 pistons and crank ?

 

20g will not quite fit straight on, 20g is front entry, 16g has the 90º entry. SO you need to mess around with a samco hose, which is tricky to get just right, or weld and aluminium elbow on the front, or change/raise the inlet manifold.

There are better turbos than the 20g now IMHO, they just cost a little more money. On a standard wrx bottom end, even one with 9000miles on (I bet it has the original rods) I wouldn't be looking to run anything more than an 18g.

I have mapped a number of 16g equiped cars that have made over 340hp on a variety of rolling roads.

Paul

 

I was under the impression that my TD05 had been converted to front entry and the TD05 20g would therefore fit straight on ?

 

If Paul mapped it, it will be just fine. I like Paul!
I think the organic clutch will let you down if you're going for it on a strip.
Much as I agree with using them on road cars, they soon fry when up against flat out gearchanges. Hard choice ahead!

 

Pauls a top bloke

I thought the organic clutch was good for around 400bhp ?

 

Well, the organic clutch in my Evo ( sorry ) is good for that at least, and has to be! but it still slipped when I hit the strip! On the road, no problem at all. Red mist, you know...
When I get around to it, I have a twin plate Cusco, that'll learn it to mess wiv me...

 

PMSL !!

Ill be getting up santa pod sometime soon so ill see how it goes

 

It is not a front entry converted TD05, standard configuration.

 

Oh,the guy I bought the car from said it was a front entry TD05 !!

What benefit do you get from converting to front entry ?

 

Why has this thread been moved to 'drivetrain' ??
