SCing or TCing an I6 - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I see a few of you have blown your I6. What sort of increases have you gained, and at what cost? Supercharging seems to be the way to go, although I know some guys that have got some pretty good figures from turbos on their I6 lately...not to mention the new turbo XR6 (detuned from 300kw!).

Have many problems been encountered?

Im looking at doing something like this with mine,but just wondering if the amount it would cost would be better spent on a deposit for an AVXR8!

You cannot beat the feeling of a good turbo motor.If set up right I would say forged pistons and a.r.p.bolts if not better rods.Or keep bottom end std and run say 6 to 8 Lp boost..Once a turbo is set up "right" they have no trouble,so long as you don't go overboard on boost etc.The cost and there is no drive in drive out places that do it. Fairfield exhaust's in Seton st do make up turbo exhaust manifold's on site..The same co. that make Haricane headers and others...Go for it you will always wished you did and it is your creation.. AAhhhh I see you are a Mexican....

I have a blown EF I6 powerdyne 9psi. If you have extractors and you want to keep them the only option you have is to supercharger. With a surpercharger you don't get the powerband a turbo gives because of the relationship between revs and boost pressure. The next point is important, once the engine is SC/TC it must get an engineers certificate. He will ask you to pass the ADR37 test (engine emissions). With mind the CAPA boys had done this test, all I had to do was get a copy and it was passed. Sweet. If you go for a turbo you may need to present the car to the RTA for testing, hassles.

The only problem with the powerdyne kit is that it is limited at 9psi. The vortex is adjustable but requires engine oil lubrication (hotter charger).

The first thing to go on my car with the auto transmission, required a complete overhaul and adjusting of the band pressure.

The car has produced 189rwkw using factory rods ( de-beamed and shot peaned), pistons (20 thou oversized) compression (9.3:1) and hypo bearings. You may have noticed I have had the engine apart, excessive blowby. So don't let tools talk you into doing up the bottom end.

PS Also running 75hp of NOS on the track. Done 12.3 sec for 1/4 mile and more to come on 'standard' engine.

What was the blower worth? Got a T5 gearbox so that should be no worries. Just in the process of getting my hands on a nice comp system too, so that solves that problem. Shouldnt have any other real problems eh? What does the supercharger do as far as torque is concerned?

blown EF 6 · 03-08-2002, 02:07

Oh! You have a T5, you know their towing capacity is lower than the auto and don't like lots of torque!

What are doing with the computer?

The torque for is engine is very smooth, feels like a V8 on steroids.

should still handle it alright though eh? they used them in everything! oh well if it breaks...itll give me an excuse to buy something better!

by the way, how much was the blower???

blown EF 6 · 03-08-2002, 02:18

Should be alright if you don't go slamming into gears, 2nd gear shaft flexs. The best box is a Tremec cost around $4500 (started to look for one myself).

The kit cost $5800 through CAPA 3 years ago

does it matter what stage your cam is? ive heard that you can have heaps of trouble if its too big.

I will be giving them a call on tuesday...will check out vortex price too

blown EF 6 · 03-08-2002, 03:12

Cams came be a real problem don't go for one with alot of overlap. This were both inlet and exhaust valves are open letting boost thru, a standard cam is better. You need a cam with less overlap and more lift. I have a crowcam #2522, around $400.

Check out Forced Air Tech They are setting up a bolt on kit for AU six cylinder (should fit EF / EL) at the moment. Should be available by mid year.
It is going to be a full bolt on kit, very neat and professional looking.
Not sure yet what the cost will be.
