Hi, I’m new to the forum and I’m from Ireland.
I’m just about to start into building a 3.0 duratec turbo, I have been looking gather more info on the build so have turned to you guys as I can’t find anything this side of the pond.

So far I have picked up an S-type jag which has the AJ duratec with VVT about 240hp. I think this would be equivalent to the Mazda 6 in the U.S.?
I’m heading to new York in a few weeks and when I’m there I intend to pick up a set of K1 conrods.
From either http://www.campbellenterprises.com/....0-Duratec-Rods-FH5440AGFB6A-K1-Rods_3434.prt
Or
http://buddyclubwholesale.com/k1_te...rods_sport_compact/fh5440agfb6a/i-589039.aspx
any of you guys any experience with dealing with these guys?


I’d like to also get a gasket kit and main and big end bearings but need to find out where to get these so far I have found http://www.store.partsdinosaur.com/page465.html
 
what car is your swap going into? As most would say that the jag 3L will not work with the Contour/mondeo because of the VVT. There needs to be a harness and ECU introduction to the vehicle. So in other words no one has swapped this motor into a contour/ cougar/ mondeo/ mystique yet.

i will be fitting it to a ford sierra cosworth. it will be a rwd set up, this is the main reason i went with a jag set up as it already has the rwd format so i will use the jag transmission which is a getrag item so should be strong enough.
i will also run a stand alone ecu, at the minute i am looking at an emerald ecu for this but there are a few others too.

its choosing the turbo is where im stuck at the minute. i've looked at precision turbos, holset hx35 and holset hx40's and GT35 garrett
what i have worked out that i want is
twin scroll
journal bearing
prefer an external waste gate
3inch exhaust outlet probably v-band
about 3-4inch inlet
thinking a 80 exhaust housing?
 
Sounds like a fun project. As for picking your turbo it is going to come down to your power goal, type of fuel, boost pressure, intercooler configuration, just to name a few. You could start with using Garrett's "boost advisor" (http://www.turbobygarrett.com/turbobygarrett/boostadviser). It asks you a series of questions and provides some recommended turbos to choose from.

It sounds like you know what options you want, but maybe not your targets. It really comes down to looking at the compressor maps to make sure you have sized it right for your application. Garrett's website has some good information on explaining how to read and use compressor maps for turbos. I would start there.

Hope that helps!
 
i race with a guy that has a 3.0 Jag motor with VVT in a miata. He is using a megasquirt to control it. Its quite the frankenstein of parts to get it to work

I'm aiming at around 400hp with a nice torque figure hopefully
The car is a drift car so will be track only, I want some thing that will spool up nicely but need the power from mid range to top end.
Not too bothered about a small bit of lag down low as I'm hoping the v6 torque can keep me going there. I'm hoping to have anti lag as an option on the ecu so it's there if I need it.
Fuel will be 97 octane pump fuel, and if nessessary I will add octane booster.
Intercooler configuration will be a large front mount and prob about 3" core with about 2.5" hard pipes
I have had a look at Garret's turbo adviser but it's the housing sizes and compressor wheels I need to study as I don't know much about all that end of things yet.
Boost pressure I will probably be looking at 14psi as I will be using the standard pistons and standard steel layred head gaskets.
Maybe I would be better looking into aftermarket pistons? If so what is available for them? As if there was something I should be looking I'd rather get it when I go out to New York in a few weeks.
I don't know yet what the limitations are of the standard form engine and it's internals are except for the rods being the weak point.

I looked through your build CSVT#49 and you've a lot of good info on there and a nice build going on.
Look forward to some running videos.

I will look up the boost adviser and see if I can understand what I need to be looking at as regards to what I need/want
Thanks
 
As soon as I get the engine stripped down I want to get it left off with a guy I get to do machining work to add the oil squirters added.
Has anyone who done this advice on doing this?
What is used for the spray jets themselves and what size of jet to use?
Thanks
 
I can get some information from a guy I know with a Mazda 6 who added squirters. He spent a lot of time figuring stuff out Ill shoot him a text soon about them, Im sure hed be happy to share and have someone benefit from his time. Hes the only person I know of who has added squirters to this motor that I know of.

Any more info on this? I'd be interested to know more about this. Is he running it n/a? Mega squirt is ok but takes a lot of messing about yourself and not many engine tuners will work with it. Plus I want reliability so I'll go for good ecu
 
Oil squirters need to be installed at the right angle to work efficiently. I had mine installed at a shop that has experience with the Duratec engines. They already have a CNC program setup to drill and tap the block for them.

Contact Kinetic Racing Engines in Westland, MI. http://www.kineticracingengines.com/default.htm

They charged me $300 for the work and I sent them the block disassembled and all cleaned up. Pics of the final results are here, http://www.contour.org/ceg-vb/showt...rived-let-the-build-begin&p=843000#post843000
 
he is running it NA for now. its got a lot of modified bits that he did to make them work, including headers, trans adaptor and a bunch of others

my understanding of it would be to aim the jet at the gudgeon pin/wrist pin when it is near TDC as this will be its hottest point?
i will contact kinetic racing engines to see if they will share the information on it.
cheers for the info and pics i'll go over this with my engine machining guy and see what he thinks, he's maybe done something similar before?
 
i had a nosey through summit racing website there and came across piston rings, but dont know which ones i need yet.
seen these ones
http://www.summitracing.com/int/parts/slp-e-970k/overview/
but need to check sizes.
also noticed they have K1 conrods but they are about $100 more expensive than buddy club or CE
so think i'll just order the bearings and piston rings
also need to look about ARP head bolts
and maybe some ARP big end bolts
 
How long has it been since you looked at megasquirt? Its come a long way in a short amount of time. In fact, they just released a new version of Tunerstudio that has autotune for the warm up enrichments. I could supply you with a base map as I have megasquirt and a D30 engine on a standalone.

My daily driver runs on MSII V3.0. I built it from scratch myself and it has never let me down once in any way. It was $330 and the best investment I have ever made with cars. Im not saying to build it yourself, a preassmbled MS2 V3.0 is about 410$ iirc.

Any standalone will easily be able to control the VVT...its just a solenoid controlling oil pressure against a 2D map of RPM vs Load or TPS. The more pulsewidth the more retard on the valve timing.

Ah I keep forgetting your in Ireland. Try contacting JetStream Motorsports. They specialize in Nobles, which have the oil squirters. They should be able to point you in the right direction for someone locally that could do the work for you. https://www.facebook.com/pages/Jetstream-Motorsport/158956534184330

I worked with Dave over there when I purchased my up-rated Noble stage II cams. He is a good guy.

I would stick with a 97 octane tune. Octane booster for the most part is snake oil, as it only bring up octane a fraction of 1 octane.
And from the test school put on adding multiple bottles doesn't really add any worth while octane after the first bottle.

Otherwise sounds like a fun project look foward to reading more on it :)
