Turbo!

Turbo and manifold installed

The turbo charger and manifold are here and already installed!

The turbo of choice is a GT35 sourced from the aftermarket (i.e. not a name brand), class type T4 with A/R (area/radius) ratio of .70 on the compressor side and .68 on the turbine side. After Ed received it he sent it out to have the seals upgraded and the rotating components balanced to a tighter specification than standard.

As anyone would know, class T4 of course defines the flow capacity (as well as flange style) which means by definition that this setup can deliver enough air for an output in the 400-800 HP range (gulp!). The A/R numbers represent just the right balance between spool-up time and output. Rather than ball bearings it uses journal bearings in order to keep it fully serviceable.

For the manifold, Ed chose a cast iron, really stout unit from ATP Turbo specifically designed for use in a turbocharged VR6 motor. It drops right in, already has the T4 style flange to match up with the turbo as well as the wastegate port.

Ed also reports that the clutch is completed to his complete satisfaction (“MUCH nicer than my 2JZ car felt like”). It has a full stroke with the expected performance stiffness and an overall fantastic “feel”.

And finally, the new Bosch EV6 injectors are on the way. These are standard issue on the 420 HP Porsche 996 Turbo with a nominal flow rate of 450cc/min each. He also tells me that these injectors are good for at least another 100 HP so, if ever needed, there is plenty of room for growth…  

Water pump, remote oil filter/cooler

After a brief (and planned) break, we’re back up again! The motor has now been fitted with a water pump, tubing and thermostat housing. This is all brand new and stock VR6.

Maybe more exciting is the remote oil filter/oil cooler arrangement: This is a complete SEO custom solution; sure it looks cool and makes serviceability a snap but the real driver is the fact that the stock oil filter location would have interfered with the new motor mount, so as a result, the filter was relocated. The oil cooler function may not be obvious, so to explain, the oil/coolant exchange takes place in the metal adapter that bolts to the engine block; the coolant return flow runs through the block, through the metal adapter (where it cools the oil), up the little black hose and into the coolant return pipe. Very neat.

In other news – the MS3 Pro Engine Management System controller is on order. This is an upgrade from the regular MS3 we had planned to go with but this way Ed does not need to add any expansion modules and such; it’s all integrated into one extremely capable unit.

Also on order is the catalytic converter. We’re going with a 3” high flow unit from APTuned, specifically for forced induction. I don’t really require a cat since they do not do emissions testing on cars older than 25 years here where I live (not sure if it is regulated at a city/county/state level) but, hey, it’s always wise to be prepared for any changes in the laws or if we move…. not to mention doing the right thing for the environment!

Ed also ordered a new 3/4" clutch master cylinder from Wilwood.... No reason to fool around with the piece of junk that I had bought from the guy who sold me the manual transmission.

Base motor + transmission go in for the final time

All of the transmission and clutch modifications are now complete so the whole schebang is going into the car for the final time. Now, all that space everywhere is of course going to be filled with intercooler, turbocharger, custom intake and exhaust manifold, fuel injection etc, so lots more to come of course!

Starter, pilot bearing, slave cylinder fitment

Parts are starting to come back from the machine shop. It's great to see how the custom pieces are coming together. Here is a picture of the pilot bearing adapter that is going to support the input shaft (with bearings too of course) and the spacer for the starter:

Here is a view of the starter motor installed with the spacers in place. Looks like a perfect fit:

 The custom flywheel is installed ....:

And here is what it looks like with the input shaft and the complete clutch installed:

Input shaft and complete clutch assembly - some top notch engineering there!

The new SpecialTAuto clutch slave cylinder had to be set back using a couple of spacers in order to clear the motor. No problem, but that also meant that the geometry for the clutch fork had to be re-worked in order to achieve the correct fulcrum. I don't have a picture of the latter, per se, but Ed is telling me that it worked out great, so the stroke and the feel of the clutch is going to be just right.

I can't tell you all how pleased I am with this project to this point! Ed and SEO Motorsports are not cutting any corners, all details are addressed - always with my satisfaction and the car's performance in mind.


New clutch, upgraded shaft coupler is installed

The complete clutch package including pressure plate, throw out bearing etc. come from Nissan 350Z. Nice to know that stock parts are available when that day comes. I am very pleased with how it turned out:

Sourcing the upgraded shaft coupler turned out to be quite the chore. None of the usual Delorean vendors were able to provide it so we turned to "crowd sourcing", i.e. the Delorean community. Turns out, there was a huge demand for these couplers and a lot of owners joined in on the order. Read all about it here. Here is a picture showing the transmission with the heavy duty shaft coupler installed (circled):

Heavy duty coupler in place. Tranny ready for high power!

VR6 first fitment

Being that this is a customer build, some things such as sizing up the engine mounts to get the entire drivetrain in the exact location can only be done using actual mearurements, so the as-is transmission and brand new adapter were mounted (no clutch) to the engine and then the entire package was "floated" into its exact, correct x-y-z location in the engine bay using the transmission mounting points as the basic reference:

Perfect fit

At this point, Ed tack welded the engine mounts together and once he was confident everything lined up as it should they were finished off and sent out for powder coating:

New engine mounting points

The ideal VR6 engine mounting points happen to be located exactly where the stock tow hooks are so they were lopped off:

... and new ones were welded on:

Then the entire engine bay was painted with oil based Rustoleum paint:


New engine anchoring points in place and engine bay looking good!

I've had very good results with grey POR-15 but, as Ed pointed out, while that may be ideal on rough and corroded surfaces, it may not be intended for overcoating an existing layer of smooth paint. This happens to be Rustoleum's strong point, so why risk it? Rustoleum it is. Good call, Ed!
