Greddy Turbo Kit

[gaki]

There are so many comment against turboing an NA engine. For one is that the internal is not as strong as the factory turbo setup engine. But how weak is the internal, in term of attaching a turbo to it?

I've seen a fair few automotive magazine from the States, with Greddy & HKS selling a bolt on Turbo Kit for the 350Z, and Greddy bolt on Turbo kit for those Hondas.

Wouldn't it be a fair argument to say that those 350Z and those hondas internal weren't meant for turbo charging, and therefore would not be as strong as.... say an RB25DET or other factory turbo setup engines?

Can some one shed a light on to this for me, so that I may understand more about what works and what dont?

It can take it Judging from your other posts, you've got an N/A tiptronic R34....if you want to talk about it sometime, give me a PM and I can show you what's involved 1st hand.

i'd like to know how much work would it be to turbo my Rb25DE - nothing crazy, i'd probably want:

run lowish boost

maybe FMIC?

What parts would I need dan?

I'm actually thinking baout going halfcut then doing a swap....

[666DAN]

Halfcut would probably be the best option unless you can get the turbo and other bolt-on bits relatively cheap.

bits would included

Turbo

Exhaust manifold

Dump-pipe & Front pipe

Injectors (stock GTS-t ones or better)

Intercooler and piping (stock or better)

ECU (R33 gtst one may work fine)

Fuel Pump

I think that's the minimum you need to get it going

headgasket... lower the compression ratio to aid in actually having a point in bolting a snail onto a higher compression n/a motor

[666DAN]

head gasket isn't essential, and just adds $1000 to process, unless you're chasing boost over 9psi don't worry about it. You'll find the low-end torque from the high compression to be rewarding enough

[gatty]

hows about some explanation into the lines that go to the turbo?

[666DAN]

I really should take some pics of under the engine bay, basically the oil feed comes from where the filter goes, the return is via the block near the sump.

The water lines are fed via the heater hose system for the climate control.

I'll g some photo's up

[gatty]

could you mate?

if you don't mind

good detail too?

i know basically nothing about the turbo lines, manifolds, etc etc good pics would be great

[HKS34R]

Go the front cut swap. Although more expensive in the short term, it will work out cheaper in the long run should you wish to modify the engine further down the track.

[gatty]

yeah i guess - but somone said i'd have to re-wire loom and shit?

[666DAN]

Looking at the wiring for the R33...the only thing I can think you may need to rewire is if you put the factory boost solenoid in. But if you don't bother just use a boost controller.

The R33 wiring is 1000 times more forgiving than in the R34.

[Squizz]

If we could do it to a R32 half pissed in a weekend you can do it to a 33.

[gatty]

if i was going to do it i'd get elec boost contoller

i found a guy who said he'd do the converison for me for 500-1000 bucks

seems resonable

[paulr33]

gatty

before you go and get it done, find out just how much for an rb30 bottom end conversion, could work out similar pricing and youll get a crapload more torque and better off boost repsonse., even with the stocker 25 head and 25 turbo it should be a monster with no lag at all.

[gatty]

what, rb30 bottom end - then turbo the current motor and run 7 PSI?

[666DAN]

Yeah RB30 bottom end is really the way to go, something I should have done...and maybe will do though.

[gatty]

surely a rb25de + rb30 bottom running 7 PSI wouldn't get more rwkw than a rb25det running 12 PSI?
