Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Turbocharger kit update

Good job Chris, just read the previous post.

Brad will get me the low CR 3.0,

and

you will get me the Turbo.

Now the bigger problem. Where's the money?

John

What will be the price? please let me know playazprez@hotmail.com

Hey its been awhile since i've been on...seems like alot of interest in this turbo sytem.

Chris I wonder if you recall we spoke about the turbo system for a 95 contour GL. I am in the process of building the turbo system using a Garrett T3.

This is a warning to members that the turbo system is not plug n' play (supercharger) which seems to be what most members think.
A turbo system requires consistent tuning unless drastic changes are made to the EMS (engine management system) See TEC2, SDS, DTA, Motec..etc, if large boost is wanted (> 10psi). These changes including varying fuel pressures and spark timing. Some turbo kits even include re-mapped chips as an alternative to going to an EMS. Will you be including this ?

From your post http://www.contour.org/cgi-ubb/ultimatebb.cgi?ubb=get_topic&f=6&t=002826 you are offering a stage 3 kit which with my build up is a stage 1 - 2. I would highly recommend offering the blow off valve or a diverter valve AND a fuel management unit as your stage 1 [low boost ... 6psi] and the intercooler option [air-to-air maybe .. as this is a cheaper unit and a lot easier install .. depending on location and size of]. As from experience [btw, I own a turbo charged CRX .. garage project ... and my bro is putting together his VW turbo 2.0 at the moment] these are a necessity or else detonation will occur and crazy EGTs will occur and lean conditions occur.

Can you please explain to me your stage 4 and stage 5 ? I don't understand what you are doing here ? Are you offering a variety of exhaust manifolds for different flow characteristics?

Anyways, my point to this post is .... EDUCATE!!! everyone please surf the web about turbos, find a hi-po shop in your neighbourhood and talk to those who have installed turbos on cars. Ask them what they think about putting together a kit. It is not a weekend bolt on project but a passion in physics and engineering. Well, good luck on the kit and see you on the street !

vball,

Depending on the need and boost levels, there will be something to manage the fuel/spark. It will probably be a chip.

The intercooler will be water/air because you will be hard pressed to find a way to plumb an air/air up front.

Stage 4&5 are just examples. There is a good chance that those items will just be options. The kit will be made to use stock exhaust manifold, uncut, and with the cats. Headers in the same shape as the manifolds will also work (i.e. MSDS).

One thing I can tell you, this turbo setup is not like most setups you might be familiar with. The turbo, piping, and intercooler is different.

As far as this being a "plug and play" application, I have a good feeling the tuning will be fairly simple. They have other kits for other vehicles that don't even require tuning to achieve optimal performance.

If anybody has reliability and longevity concerns, they have vehicles with their turbo kit on them that have gone over 100,000 miles with no problems.

Believe me, I want to give as much info as I can. However, the manufacturer is not equipped to handle 200 calls a day from people wanting to get a status on the Contour/Cougar turbo kit.

Thanks for your patience,

What about boost for my POS returnless fuel system?

I don't see why other people can't get forced induction to work with returnless systems when the new Miatas have the same shiznit and STILL can be turbocharged/supercharged.
I remember reading up on an install on a 2001(?) Miata and they added some sort of restrictor in the return line on the pump (it's all done in the tank), to boost fuel pressure. Jackson Supercharger were the guys doing it. Surely something similar could be done on the reutrnless Contours!

There are a few ways to get a returnless system to put out more fuel.

1. Bigger injectors
2. Bigger fuel pump
3. Additional fuel injector(s)-(7th injector with piggyback controller, Paxton)
4. Trick the PCM into thinking it needs to put out more fuel (mess with the MAF, IAT, or O2 sensors)

These mods might also be used in combination. That "restrictor" trick you are referring to only works on return systems. Nothing to restrict on returnless.

The manufacturer for this turbo kit has found a way to work with the returnless fuel system on other cars. They feel they can get it to work on the Contour as well.

Who is the manufacturer? Why are there 50 posts on here about a turbo kit and not one has said who is developing it? Rough numbers might be nice, a price +-500 or even +-1000 would mean something but means nothing without some knowledge of the product for comparison.
