LOLOL, $230? What kind of a turbo setup is that?
You're already out at least like $750+ to turbocharge a non-turbo a second or third-gen Supra (or likewise, a Cressida)... you know, the Supras with popup headlights. And turbo Supra manifolds bolt up. And these 2.8L 12-valve or 3.0L 24-valve inline six engines can actually take some boost while stock (stock boost from the '86.5-'92 Supra is <7psi). No guarantees that a DOHC Zetec will take much boost at all.
Trust me man, I know my turbo game (can't say I've DONE it, just KNOW it).
- - custom exhaust manifold (unless a kit is offered somewhere or one from another existing factory turbo car bolts up; it'* possible to turbocharge 2.2L four-cylinder Camrys this way using an older Celica'* turbos, lol)
- the turbo... generally your manifold is custom-made around it. How big? What are you looking for in the turbo? Big boost, big lag? Smaller boost, zero-to-none lag?
- oil return lines into your oil pan, as well as other assorted lines, ie, cooling.
- blowoff valve; waste gate.
- BIG exhaust. No sense in turboing a car and retaining a pee-shooter exhaust. 3" downpipe, and at least 2.5" from then on. Ah hell, 3" all the way back. Quality straight-through muffler. That'll get the turbo boosting at its best.
- some sort of intercooler setup. The intercooler core itself can be had in any size, as long as it fits. You may have to fab up all this stuff. To be turbocharging a car without an IC is not feasible at all.
- fuel delivery. Rising Rate Fuel Pressure Regulator (RRFPR), fuel pump, bigger injectors, boost & air-fuel ratio gauges are all a MUST.
- Computer tuning. Your stock engine computer won't know how to deliver that extra fuel. Low boost may be okay with a piggyback on the ECU, but anything more and you'll need standalone engine management.
This $230 won't be for a kit of any kind. Generally, kit makers have to make a profit, you know
If anything, all that this $230 will get you is a used
turbo. And if you're really lucky, a manifold. And you'll only be able to use this manifold if you buy all this turbo gear from somebody who'* done with a previous DOHC Zetec project. And who knows, this amount of money may get you a hunk of fins and metal that needs a rebuild. Which'll cost more than $230 alone.
Like an L67, mods (ie, pulleys) can't be just slapped on. Proper preparation and tuning beforehand is a must (ie, rockers, computer tuning, etc). Killer, you don't know enough about the turbo game. Hit up Google. Hit up Contours.org. Anywhere that can help you.
