Looking Into Turbo

[1nz]

Im also in process on installing an NCP31 HKS 1NZ-FE Bodykit on my yaris got the turbokit, rmanage ultimate n greddy pressure sensor, still saving to get an injector RC, FIC or Bosch/ Walbro 255lph fuel pump, double head gasket and custom piping

dude, if you want the turbo inlet to be on the passenger side........... turn it around and reclock the inlet side.

oh and do a top mount intercooler.

[mrbond]

^ yeah, just like the JDM NCP91. You'd probably need to either get a new hood, which would look awesome, or do some under-hood air rerouting.

or just cut a scoop goin down into the IC and fiberglass/paint and call it a day

You can do that with any T25 turbo and with a regular revhard manifold...

No need for anything custom for what you have in mind...

Actually a top mount intercooler is what I had in mind. I was thinking about using the kaminari hood and mount the intercooler in front of the engine.



My main concern with switching the turbo around is it not fitting, you seem to have a lot of space behind the engine so I would just feel more comfortable knowing that it would surely fit.

Aren't revhard manifolds the same quality as ebay? where would you pick one up?

Also I think i'd rather get a Turbinetech manifold imo.

Look how close that is to the brake lines.

I would suggest that you might want to get the pistons slightly over sized, say 75.5mm rather then standard size at 75mm.

Due to wear and tear the cylinder bore might be a little worn out and hence a slightly over sized pistons will ensure the rings fit in nicely.

Best if you could get your mech to properly measure the bores to determine how much larger you need to go if you want to be really sure.

It is always better to be safe than sorry later, just my 2 cents.

By the way, I got my CP pistons from Race Engineering together with the piston rings and side skirt coating for less than USD 600. The compression ratio is 9.0 and the piston design is flat top.

now i've been comparing supercharger vs turbo cost and this is what i came up with is that for 2-3k i can get the hks turbo kit and for 3-4k i can get the blitz supercharger. My question is EMS, once again... I know I'm going to need a ems for the turbo but i see tons of people running the supercharger w/o. Now I can find a shop that will tune the yaris my question is if it's worth it to grab the hks kit, get some custom piping done with an intercooler and try and tune that or grab the supercharger and play it safe. I just have a gut feeling that a turbo would make my car go boom if something was slightly wrong with my setup and for the little extra the supercharger would be safe and easier to maintain in the long run. Am I just being paranoid and think I should go for the hks turbo? I'm not going to buy it till summer when I have a place to install the turbo.

Also I was comparing weight to power ratio against other cars and I found that with the supercharger you should technically be about as fast as a stock rsx type s or prelude and with the turbo you should be about as fast as a stock wrx( not the 09+ with 265bhp)

[1nz]

it could actaully beat the rsx s, tested against one of those

[RacerFreakXXX]

supercharger or turbo

[cali yaris]

get the TRD trans mount, you won't need the torque damper.

beating a dead horse here

top mount + meth injection + HKS kit (that comes with engine management)

skip the front mount

[RacerFreakXXX]

for intake and top mount intercooler i was thinking about running the intake tube up against the firewall and then use a wider diameter tube leading up to the intake and then putting a long thin intercooler more towards the front of the engine, over the intake manifold. Doing this would eliminate the issue of heat soak if you use a vented hood, such as c-one or kaminari. Also running an intake tube along the front of the engine would interfere with the radiator hosing. Opinions?

[Tamago]

do it.

i wont hate you for copying my setup either ;) if you so choose

[RacerFreakXXX]

I love your little custom turbo inlet (yes i searched the scion forums) and your bottom mount turbo design or even the super top mount but, custom piping is the furthest I'd go. I'm not going to start the build till next spring/summer. Like i said I have to use my buddies garage and a 93 240sx coupe is sitting in there ripped apart awaiting an sr and some power by max coilovers. I know he said he is fully building the car to race spec so I hope it's done by summer. Until then I'm gonna save and build

Honestly this is the exact turbo setup I want (found on changchewsoon's blog):



link to original site, click NCP91
my translation:
-greddy turbo
-blitz sus intake
-hks f con pro
-custom turbo manifold, piping, and intercooler
-370cc injectors

I believe this is the infamouse zage kit with a greddy turbo and a blitz intake. After looking at the hks kit I am 99.9% sure it is a bottom mount kit, unlike the greddy kit. If that's so, that means I'm going to shoot for the same setup as in that pic.
