With all of the type 4 turbos that folks on this forum are building, and people like the two Jonas's showing what can be done with a some creativity, I thought I would post my type 4 turbo specs.

Engine:

- Type 4 2.0 GA series engine, stock, has not been rebuilt, from a '73 914, using stock head gaskets
- CB performance dry sump oil pump with 8 litre oil tank
- 96 plate mesa cooler with oil T-stat
- FAT Performance 911 cooling system with custom directional vanes inside shroud for much improved air distribution
- CSP 1.5L breather box
- BAS 21152 header system slightly modified for turbo attachment

Intake / Fuel System:

- Custom intake system using 914 2.0 runner castings placing injectors in stock position
- 52mm Ford Taurus TB with IAC valve
- 4 x 40 Lb/hr (420 cc/min) Accel fuel injectors with custom bungs by www.vdubengineering.com
- MSD 43 GPH (2713 cc/min) HP fuel pump
- Carter 30 GPH (1893 cc/min) LP fuel pump
- MSD Boost sensitive fuel pressure regulator
- 1.0 L custom made surge tank
- 5/16" fuel feed line, stock return line to fuel filler neck
- 9/16" ID billet fuel rails with -6AN fittings

Electronics / Ignition:

- Megasquirt V2.2 board running MS&S - Extra
- FORD EDIS ignition system
- 8.5mm custom ignition wires
- Innovative LC-1 wideband O2 sensor and controller (not installed yet)
- Custom made 8 channel datalogger ( 4 CHT, 911 fan intake temp, ambient air temp, oil temp, rear wheel speed) Have wired up my VDO CHT gauge to this logger to show the highest CHT of the 4 cylinders, updated every second

Turbo system:

- TD04L-13T from a 2003 WRX (360-400 cfm @ 13.5 psi) stock
- PWR air to water barrel intercooler (4" x 6", 390 cfm rated to 270 hp)
- 2.25" piping from turbo to intercooler to TB
- Tilton differential/oil cooler scavenge pump to scavenge low mounted turbo
- Ford F150 Lightning intercooler water pump (not installed yet)
- Yamaha YZ125 radiator X 2 (not mounted yet)
- HKS SSQV BOV

Progress:

Everything is installed and wired up except for the LC-1 and water cooling system for the intercooler. I am just waiting for my ignition wires to come in before I can install them and perform a N/A start up and idle to make sure the MS is working. Hope to start engine in a week.

Next step is to weld up a 3" dia down pipe (not too difficult) and then install the LC-1. I am not sure about a muffler at this time as I don't think there is room for one !

Then install the YZ125 radiators and water pump for the intercooler

I am looking for about 160 - 180 fwhp for this summer (hope the motor stays together) and then will look at opening up the case winter 2006/2007 if anything needs attention.

Wish me luck !

These pics were taken about 3 weeks ago, engine bay is all tidy now.

VERY nice work!! Looks outstanding and a very clean installation thus far. Keep up the good work. Thanks for the pics!!

Wow, keep us posted ...

Cool, looking good!


cheers,
type3

Looks great!!

The only problem I see is the stock head gaskets

Really SWEET header! the headgaskets is not a big problem, just change them every week of my own experience they work with boost up to 0,9bar but they constantly blow with 1,4 bar of boost.. (dont really know those numbers in PSI)

Damn. That looks clean. I was possibly thinking of using the same header...

Good luck!

Wooooooooooooosh

did you cut the body for fuel rail and injector clearance?

Thanks for all of the comments.

The reason I am using the head gaskets is because the motor has never been apart, and still runs strong. If I blow a gasket, then that will give me a reason to pull the motor and upgrade the internals a bit

I don't plan on running crazy boost this summer, only about 10 psi max.

I did have to cut the "shelves" on each side of the engine bay for rail / injector clearance, only because the engine "rocks" clockwise (when looking from the rear). If the engine did not rock, then the clearancing would be really minor. I had to cut about 1.5" into the shelves on each side.

A solution would be to re-weld the shelves in about 1" higher than their original position, will do this winter 2006/2007

Still have not received my plug wires .... just itching to start this up !

Sandeep

Like other have already mentioned: very clean install! I always have a problem with that
The location of the turbo in combination with the Ahnendorp header looks to be the most logical one. Its also a very good one IMHO, as the heat can easily get away from the turbo in that spot.
You seem to have used all the 'right', again imho..

So, it must work very well

BTW, did you make the case-ventilation part in the dizzy location yourself?
(very nice)

Looks great Sandeep, awesome spec. The whole Beetle is impressive!

More pics, really good to at.

Will you be resuming your cooling tuning/datalogging? Now, after turning up the heat abit? All in good time, eh?

Thanks for the comments

The future goal of this engine will be about 250 hp. I have an idea of what it will take to make this amount of hp with a T4, but will be happy with 160-180 fwhp for now.

I want to wait to see what Jake has up his sleeve with his turbo T4 program.

The aluminum dizzy plug was made by www.vdubengineering.com and is really a nice peice. The bottom part that fits in the case is spec'd to the dimensions of a 050 dizzy in diameter, including the o-ring seal, and is drilled all the way through and tapped with a 3/8" NPT. A -8AN fitting with 1/2" ID pushlok hose feeds into the CSP breather.

I am still unsure what to do with the 2 top vents that once were connected to the tops of the carbs I had. Do I just put a filter on the opennings or do I cannect them to the intake pipe of the turbo ?

I hope the refinements I made with the 911 cooling directional vanes will be enought with the extra heat but the logger is ready to go .... STILL waiting for ignition wires.

Will post more pics and some video when this thing is ready to fire up !

GOT THE IGNITION WIRES IN THE MAIL !

This will be a very interesting weekend for sure.

Put some kind of vaccum on those ports or you will have oil everywhere In the filter before the turbo will work! In the downpipe with the "v8" style connectors will work too

Hi Sandeep. I was wondering if you have any pics of the parcel tray area?.

Looks sweet.
