skyline turbo in a zook

[zookieboi]

i probably sound like all the other kids that want to make their zooks the next ricers but im not. My friend is twin turboing his skyline and giving the old stock turbo to me. ive read that people use these turbo's for them and run them low about 4 psi or around that. This 4 psi mark is what i want.. nothing too stupid, paired with large tyres say 32 inch itll have heaps of power and yet still have good traction cause of the large tyre diameter.

open to all opinions and will trash the idea if you guys think its stupid.
i can also get manifolds made up etc for it.

[suzukigav]

ha ha still have traction...That's a good one.

[grimbo]

Just curious why people think power is a good idea in a Sierra rather than getting appropriate gearing?

well you can see where im coming from. constructive comments only please..

well mainly for fun. i dont see any other reason lol
i just want to know if it can be done and still be appropriate for 4x4 ing

[drakan69]

no too big for the suzuki's 1.3

maybe if you had an efi 1.6 and the turbo was off a series 2 r33 (i think they were the ones with the ceramic turbine wheel) because they spool up pretty quick. But other than that

and get a small turbo off ebay

doooo ittttttttt....i know i want to

"heaps of power" ahahhahahahah can't half tell it's the school holidays

thanks mate.

any one else got an opinion on this?

I went out a few months back with a shorty patrol on 38" swampers, standard gearing with an RB25DET - twin-cam turbo (T28 Turbo) (245 to 250 hp and 319 N·m) in it and this thing f*ken hammered. I can't imagine what it would do to a zook driveline!

As with that 4age turbo thread...Its too much power zookboi.

I'm putting in a 20v NA 4age and this thing has 160hp/120kw which is probably going to be at the upper limit of a stock driveline. I'll be upgrading my rear axles and driveshafts as well. my front already has HD cvs and 26spline axles... Mine is geared as well.

yeah there is alot of problems with adding power to a zook. although the total increase with weber + the turbo and exaust wouldnt be more than say. 50%, so you think this power increase will open pandoras box on my driveshaft?

[grimbo]

driveshafts, axles, chassis in some circ umstances, what about your braking that will also need a major upgrade. Sierras are built for what, 60kw, so suddenly tripling the power you have alot of areas that need addressing as well.

But I can't say that out loud anymore it upsets people

my sierra is a stockman with front disc brakes and when i step on the brakes hard.. you could say it has good brakes lol. maybe because its so light. only problem is the back end swings around sometimes.. but most old utes have this problem.

what kind of weber are you going to be using, and where did you get it from? keeping in mind it has to be boost referenced to handle air pressure not just volume. Also what are you going to be using to control timing of your spark?

Not wanting to pick holes in your dreams, just interested in how much research you've done on this mod.
Speaking of mods, you know if you do this conversion you wont be able to drive it on anything under an open license, and no-one will cover you (3rd party) until your 25, unless your older already?

[grimbo]

how old are you? Isn't their power restrictions in force for P platers?

i havnt even begun to research timing issues etc. right now it looks like a lot of work. and i am 18 on my p's dont buy insurance. saves money =P
and cops wont suspect a lil zook having a turbo under the hood lol ill jsut put a fairing over it haha

its not goign to be something i drive every day either though.
i have a jacked up shorty vitara =)

If this is going to see the road, check what you need to do to legally drive it. I would think that an engineer will require a much improved suzuki brake system. What model skyline. 4psi is not much boost. For that small amount of boost you would be better off getting a smaller turbo with much better response time. If you plan to run 32's with stock gearing, you will still have the issue of being out of the most efficient part of the motors opperating range, so you will not gain anywhere near the driveablility that is on offer with correct gearing. Also allow to inject the motor, as carbys and turbo's are just a PITA.

I have no problem with a turbo zook, but there is a fair bit to look into. Depending on what turbo you are getting, you probably would be better off starting from scratch. See if you can get some more infomation.

Layto....

I missread your post. I thought you were thinking of dumping the whole engine from the skyline into your sierra.

If you want to do something cool and have a turbo setup that would spool quickly on a zook look at a twin turbo setup with the IHI RHB51 660cc (2 cylinders per turbo) turbo from a Kei Class jap car. I thought about doing this and then went the 20v 4age in the end...

I reckon this setup would rock on a zook. Plenty of room to setup the twin turbos and would give great usable power as the displacement for 2 cylinders is close to a stock 660cc (1300/2=650cc)

that would be a cool project.

Note: I know nothing about turbo charging engines...in theory it sounds good, but someone might care to correct my recommendation for this setup.

i shoulda explained in more detail the specs of this conversion

the turbo is out of a r33 gtst. meant for a 2.5 litre engine it runs his at 8 psi and goes to 14 no problem. the only reason i mentioned this turbo is cause hes giving it to me other wise i would use a small turbo maybe a t02 garret or something of this nature.

I like this idea ill look into it

[drakan69]

I'm pretty sure you need a min of 3 cylinders to power a turbo properly, something about exhaust gas pulses

[zookieboi]

[quote="lay80n"]

ill only be running 4 psi and will have a weber carburettor.

[drakan69]

weber boost referenced - $600
MSD boost timing master - $360
o2 air fuel ratio meter - $360
boost guage - $200
intercooler/plumbing (ebay) - $500
2nd hand plumb back BOV - $100
exhaust manifold (mates rates) - $400?
rest of exhaust - $300?
2nd hand turbo T2 or such (ebay)- $350 (good condition running)
fittings silcon and worm drives - $100
nuts bolts and brackets for intercooler mounting - $150
+ labor to install and tune 1 guy @ $77/hour for 12-14 hours
labor - $1,000

total $4,420

max expected power after all of this ~ 50-60rwhp?

it's a bit of an over-the-top list but i'm sure there would be things i'm forgetting about that would cost extra.

silver top 4age conversion would cost say $6,000 (including t-50)
100-120rwhp
+ upgraded diffs and drive shafts = more $

[zookieboi]

your weber will not be able to handle positive boost pressure, therefore you motor will run lean, and you may blow the seals on your carby.
You could get your weber rebuilt for boost, that could cost you upwards of $600.
MSD boost timing masters are around $350 and allow you to retard the timing up to 3

when me and my mate were playing around with his skyline's psi ( its meant for 8 psi ) it didnt start missing untill 11-12 psi.

Grimbo,

Im one for power, sandhilling needs it, slow just looses traction. Have you ever tried climbing sandhills where traction isnt there.

Rocks, yes, slow and steady wins the race, sand, power is the go.

[zookieboi]

Do you guys think i should just try it and then go from there. get manifolds made up. lower compression and all that stick the turbo in and see how it goes with the weber carburettor 32/36 on, bought off ebay.

[sierrajim]

The turbo will be the cheap part, save the money, buy some gears and weld your diffs.

[tanshi]

i think the general concensus is that you should research this course of action. and make the decision your self based on that. some think its a good idea and some dont. its your car, if you wanna do it, do it but be prepared first.

@_@ 4k+
thats quite a pricey excercise for that kind of power increase, but thats the kind of power i want.
+ rear air lockers too
then again im willing to spend that type of money on my car. Ill be keeping it for some years yet.

any more opinions??

You are aware that a RB25DET has fuel injection and a much better ignition system than a zook. Research is your friend. There is much more to a good reliable turbo system than you are looking at so far. Drakan's list should give you an idea. Why not fit a 4A-GZE motor, more power, factory reliability (motor build for boost).

well mainly i know turbo is the wrong way about it but i still want to retain some fuel economy. and also i think with just a turbo the drive line may stand a chance if i dont thrash it everywhere which i wont. with a hotted up toyota engine itll be a full driveline upgrade too
