Rear Mounted Turbo (scratch build)

DIGItonium · 08-24-2010, 11:23 PM

Have you guys seen the vids of a blue IS-F with Twin Rear Mounted Turbos? It's a bit raspy.

[EDIT] Ninja edit... thanks AK!

Yes.

If significant boost comes on before 4.5 K I will be impressed...

i put an sts kit on my buddies 350z and while adjusting his boost control we could make over 10psi by 4500. as soon as you hit 4000 there was good boost. besides the gearing and redline on these cars means that spool at 4000 will let you let you hold boost for a 1/4 mile run due to the gearing and high redline.

Eh, derisive responses and gainsaying accepted -- I hope it works out and turns out to be a good option to consider.

I generally see these set ups making very uneven power, and therefore being preferable for drag racing over daily driving, but I've been wrong before...

on that other setup i reached full boost @3800 rpm (12psi).which the motor was smaller, i am torn between selling my gears or going back stock. With my 8k shift point and stock gears... man are they going to be long....i was kinda thinking to help off-set the boost response it would be a good idea to keep the agressive gearing, but traction will be an issue when boost comes in.

My buddy had a rear mount on his 3.8 camaro. Not too shitty. Ended up scrapping it for a built LS1

I seen a Porsche once with rear mounted turbo. It was awesome....

Really though good luck, im thinking of going this route myself.

jnaut · 08-25-2010, 01:47 PM

NYBladeZ · 08-25-2010, 02:41 PM

The Porsches have a rear mounted engine so a rear mounted turbo is a given.

theDreamer · 08-25-2010, 02:54 PM

Interesting, in for good results hopefully.

Sorry that was my attempt of a joke.

What turbo did you go with J?

RCZ · 08-25-2010, 06:27 PM

Jay, dont rev to 8k with turbo. Not recommended IMO.
