Hi guys, first post and I'm already asking annoying questions...

I'm looking into fabbing a turbo set-up on my Ford ZX2. The best way I can see to fit a turbo in my engine bay would be to mount it approx. 2-3 feet away from the exhaust manifold (where my battery currently resides)and plumb the exhaust to the turbo, rather than directly mounting the turbo to the mani itself.

What are the major drawbacks of this set-up? Why do I not see this very often? What would be the best I.D. piping to run from the mani to the turbo?

Thanks for your help!

just get a custom made manifold that goes to the position where you want your turbo.

 

Others have bolted T25's and RHB5's to the stock mani (using a custom adapter plate), however, I'm looking to move the turbo itself to more convenient place within the engine bay.

Really what I'm asking is "does moving the turbo away from the mani. cause any major issues?" Like decreased exhaust flow velocity/temps or increased spool time.

Like most others starting out, I'm looking to boost between 4-6 psi reliably.

Thanks,

Justin

 

i'm guessing there might be more lag.

but I should also note, people dont use stock mani's,
they use HFor CX or STD manifolds..

and no one turbocharges those cars thats for sure.
most other stock dseries manis wont work good with a turbo.
adapter plate or not.

 

Ha, I wish there was the aftermarket you Honda guys have for my car.

I'm running a 2001 Ford ZX2 (escort). It a 2.0 DOHC engine with a stock log mani. and returnless fuel system (I know, big PITA) and DIS.

I'm playing around with the idea of running my Kamikaze 4-1 header over (approx. 3' of exhaust tubing) using a custom fabbed 'S' pipe (I'm an effective, but not so pretty welder).

The collector at the bottom of my Kami is 2.5". If I run a 2.5" 'S' pipe to the turbo will I get sufficent exhaust energy to sp[ool a tiny turbo (T25 or RHB5)?

Thanks for the replies, this is turning out to be an interesting project!

 

remember that the oil system for the turbo will be gravity drain. if you move the turbo too far away from the block, the drain line must be longer, and generally at less of a vertical angle. more chance for the drain line to plug and blow oil through the compressor seals.

if you're an effective welder, maybe you'd be better off fabbing a manifold as well. it's not that hard..

 

i second that
