A friend has a MY94 wagon JDM scooby turbo with FMIC, 10mm manifold insulator spacers, TD05 20G turbo, billet fuel rails etc.

Turbo is AFP TD05 20G so is a front entry turbo.
Currently using 90 degree bent silicone pipe in front of manifold rear to get air in from MAF/Air filter etc.

What he wants to do is convert the inlet pipework to proper front entry feed to the turbo going under the manifold.


He's been told he needs to fit later ( phase 1.5 ?? ) manifold and power steering pump and reservoir to make clearance?


Is this right. and any other things he needs to do / get to do the job?
Can you buy a kit of parts & instructions to do this?

Thanks

i think your friend will get away with it if he fits the later power steering pump or even if he relocates the power steering reservoir, your best bet is to do a search on here for a "how to"

I'm sure you can get a silicone 90degree pipe so no need to change inlet or any other bits,someone correct me if I'm wrong though

He already has that. WAKE UP!

That's the easiest way of doing it, as far as I'm aware though it is possible using the early manifold.

If using the early manifold I'd reckon you'd need to go parallel fuel rails, to try and clear some more space under the manifold.

o sh*t i didnt read properly lol,thought he wanted to fit a 20g that has front entry and needed it 90degree lol

think u need a phase 1.5 inlet and pas reservoir and thats it,can be wrong AGAIN lol

You can use the existing manifold mate. Get a set of these...

97 onwards Ps pump will help or newage remote, fuel rails will need slight modification. Also the metal coolant pipe that runs to the base of the header tank will need modding. You can remove the small pipe that attaches to the crossover pipe and replace it with a rubber hose joining it to the metal pipe near the oil filler neck if that makes sense?

Have a car here done this way running a FP green with a 3in inlet on a phase 1 manifold.

Thanks guys, useful advice!

It's already got Carl Davey 10mm manifold insulator spacers but could double up or go to the 20mm ones.

It's my old car, so want to help the new owner with it!

The PS pump/res would get in theway of the inlet pipe under the manifold so it needsto move somehow, 2 ideas above to look into.

Cheers, keep 'em coming!

Why does he want to fit such a huge and laggy turbo?
Would he not be better off with a 16G as there is no other mods mentioned and a 20G will just break his car is such a short period of time....

Sorry, didn't want to bloat the thread, but the car is "built"
- forged pistons, steel rods, comp bearings, full H&S 3" decat exhaust, lightweight pullies and flywheel, AP Organic clutch, PPG geaset in later 'box, Quaife front LSD, high flow/pressure oil pump, FMIC, GT spec2 headers lagged, STi4 heads & cams, Apexi AVC-R, Apexi PFC, forge recirc adjustable dump valve, billet fuel rails / parralel feed 800CC injectors with braided hoses / ally ends, Walbro fuel pump, fuel reg, resonator delete, cold air induction, upgraded throttle body, manifold and water head tank thermal isolators, Iridium 2 grade colder plugs,

and loads I forget, as well as AST suspension, fully PU bushed and all adjustable whiteline bits, big brakes etc.

Was running 360 bhp / 325 lb ft on the TD05 16G ( well lane rollers ), uprated to 20G to break the 400 bhp barrier was 384 bhp / 360 lb ft at rolling road day in December ( other rollers ).


Andy F mapped.

The TD05 20G isn't laggy on this engine IMHO.

Ohh yeah, last time out at Scoobyshoot out at 360 bhp did a 12.08s 1/4 mile at 117 mph terminal.

Not bad for a daily driver shopping car! ( yes it is a wagon! ).


Next step to release the potential is to help the airflow into the turbo / engine by using the 20g front entry and change the inlet route to suit.

The car will not produce any more power front entry over a swept 90 degree bend on the front of the turbo compressor intake. It is a lot of work for no gain.
The OE inlet manifold and 20mm thermal spacers will allow you to go front entry if you are sure that is what you want to do. No need to go to a 1.5 inlet manifold although it is easier to do but causes its own problems with throttle linkage and idle control.
You do not need to go parallel fuel rail.
You may or may not have to alter the power steering reservoir

Thanks Harvey.

We were looking to straighten the airflow path out - it is very squashed 90 silicone hose going into turbo, expected small improvement in mid range driveabilioty and upto 10 bhp with FR inlet pipe.

Will only continue if the bits can be done cheaply!

Suggest you go up to Darlington and see Harvey, get FE mod and special up pipe for the headers while there, and maybe a remap to get the best out of them and Apexi & AVC-R.

You still have a bend on front entry setups, it's just at the front of the inlet by the ps pump instead of by the turbo! I really can't see the hassle is worth it.

thanks guys
