If you know of a business that does parts or work for FJ20’s please add to the list in there area of specialty.
• ECU’s / Computers:
There is too many to list. Pretty much every stand alone after market computer can be wired onto an FJ20.
• Inlet manifold and plenum:
The standard one is pretty good for upto 350+rwhp.
Then you can modify plenum by cutting off the standard throttle body flange and putting a bigger throttle body on it. No need to go bigger than 76mm on a street or track car. Good for 500-600rwhp.
• Another trick if you are revving your FJ over 7000rpm with the standard inlet manifold is to move the power curve up the rev range by shortening the inlet manifold runners.
This is not 100% accurate and should only be used as a guide. 1” off for FJ’s revving to 7500rpm. 2” off for engines revving to 8500rpm.
Better power curve.
• For a full drag engine time for a custom inlet manifold and large throttle body.
Best to talk to your work shop or engine builder on this.
There are so many good fabricators around it shouldn’t be to hard finding someone with good skills and the know how to build an inlet manifold. Gould places to start looking would be.
• Bolt on fuel rails
The standard fuel rails are not that bad.
Billet Turbochargers keep CNC machined billet FJ20 fuel rails to suit 11mm & 14mm injectors in stock.
They can be custom order anodized any colour but come standard in a choice of Red, Blue and Purple. These are the Fantasy fuel rails that are now available through Billet Turbochargers and all of the Billet Turbochargers dealers.
• Fuel injectors:
There are so many options best to talk to the person tuning your car.
The Fantasy / Billet Turbochargers fuel rail’s cover most brands of top feed injectors.
• Bolt on Turbo’s.
Most T03 & T3/4 turbo’s will bolt onto the factory exhaust manifold but you will need new dump pipe and oil lines, and if it is a water cooled turbo water lines.
Next option is a high flow. This turbo will bolt straight back on. Any reputable turbo repair shop can do this. I recommend MR Turbo Australia.
Billet Turbochargers do twin ball bearing turbo’s from 300hp to 500hp using the factory FJ20 exhaust housing. The Billet Turbo’s will bolt to the factory manifold and factory dump pipe. If ordered for the FJ20 they will come Oil cooled only there for only needing new oil lines.
• Exhaust manifolds:
I think Brian from these forums may have a contact to FJ20 exhaust manifolds as well.
If you have a serious race car and want to talk turbo’s a and manifold’s (Fantasy)
• Dump Pipe & Exhaust:
3” or bigger people! Nothing less.
You want as free flowing exhaust as possible on any turbo car. Exhaust system back pressure on a turbo engine is evil.
If a shop tells you you need back pressure on a turbocharged engine go to another shop. They have know idea what they are talking about.
Follow workmanship advice as in the Intercooler & Plumbing section.
• Intercooler & Plumbing:
The Ebay coolers are not that bad as long as they don’t leak.
Any good performance shop should be able to fit an intercooler and do the pipes.
Best bet is to check out a few places in your area and pick the one with the best workmanship. Check out there welding. If there custom pipes are polished and don’t seam to have any welds there is a good chance they have ground them back and polished them off because they were not very good. Ask to have a look at there work un-polished.
• Engine parts:
Best to talk to your engine builder. So many engine builders have very strong opinions on what works and what doesn’t work.
Here are some brands for parts made for FJ’s
Crower, Crank, Rod’s, Pistons, Sprigs.
Many companies do cams for FJ20’s. My advice is to talk to someone with experience with camed FJ’s.
Try Ben Diggles or Jeff Watson, Mark Ashford, The guy’s from Plasma Man or Insight performance. V&E Rigoli.
I remember Mark Ashford telling me he pick up something like 6 tenths from changing cam manufactures.
Billet Turbochargers, re-man pin adjustable cam gears.
Ben Diggles, re-man pin adjustable cam gears.
Be careful buying slid adjustable cam gears for FJ’s. I have seen major disasters from locally made slid adjustable cam gears. I you do find someone making them be sure they have at leased 5 points where they bolt down.
SW Motorsport AKA (Stewart Wilkins) He has just about every FJ20 engine part you can think of.
