R33 NA bolt on conversion

[MirKz]

Hey all,

well ive finally decided that im gonna bolt on a turbo onto my car,

I have a front mount for the car, a standard r33 gtst turbo

and plan to get gtst ecu, and injectors.

I am also leaving the high compression pistons in, rather than getting low compression in.

Has anyone else here (im sure someone has) done this before?

If so, how did it go? any problems things i should look out for ?

ive still got to get some of the stuff for my car yet and it wont be getting done for another few weeks at least...

hey mate, firstly check the link in my sig

in there is a list of what you will need, also feedback frmo Dan whom did it to his r34

it's a bit more involved than just bolting on new manifold etc etc and starting the car - holes need to be bored into the block/sump for oil/water lines etc all is in that topic feel free to ask any questions in there as it will also help me

Mind sharing where you got your bits from and how much for?

good luck mate

so far i only have the turbo and intercooler.

bought the turbo off of a member of SAU forums.

and bought the intercooler brand new for $400.

not sure on dimensions. got it through a friend

The ecu and injectors i will be getting through a friend or 2nd hand from somewhere...

cheers for the link, checkin it out now.

[gatty]

no worries mate, feel free to ask questions there - help us both

You'll also need to keep the boost low, around 0.7 I believe, not that I've done this but someone on the UK site, www.skylineowners.com has.

Firstly..hoorah another one

Secondly, just keep an eye on gatty's link, that'll be the best place to look.

0.7..that's a fair bit of boost for the high compression...I'm only on 0.4 hoping to go to 0.6

[MirKz]

really?

damn i was expecting to run a max of 7-9psi.

I suppose the lower boost would be better.

What sort of power do u have Dan?

1/4 mile times?

dyno?

Im thinking of getting it done at a workshop so it doesnt take me forever to get it done (whereas if i did it myself it would take forever and i would be bound to stuff something up)

um how do you get into file of yours re the conversion

could you be a bit more specific about where to find that info . by .7 what psi do you mean ( i figure 10 psi ) , am i correct

[666DAN]

Don, go here http://www.skylinesaustralia.com/forums/sh...newpost&t=63667

I'm assuming he means 0.7 bar...which I wouldn't call low boost for a 10:1 engine...the effective compression ratio would be pretty high.

[666DAN]

Also this is a rough way of working out what pressure you can shove in your newly boosted N/A.

Going by this you can see 12psi in an RB25DET is ~ 9psi in an RB25DE, which is as far as I'd personally take my one for now, so seems quite accurate

Note it's a very rough way as dynamic compression is probably a more useful indicator, and this can be changed with cams.

Can't do it. It won't work.

At least give a reason Jay...you're more creative than that!

hi mate,

if i were you, try and find a rb25det bottom end, so that you an run normal boost, you Na head will fit onto the det block which is good. also then you will need bigger injectors, either a new ecu, or try and get your old one remapped. make sure you get your turbo checked just incase it has leaks or it is blown. you will also need exhaust manifold.

if you want to use your NA motor, the most boost you can run is 6psi which isnt very high considering you have a front mount.

the best thing to do is either find a bottom end or get a half cut, less hassels and you can boost it up higher.

Turbo'ing an NA is inconceivable and you'd have to be crazy to even entertain the idea. You'd need at least one spare weekend a lot of parts and too much beer...

[Driver]

hah to much beer + to many parts = too much money..

Buy a rb25det - probly work out cheaper in the long run, and the final product will be so much better.

[Squizz]

Too much money? We did my conversion for under a grand!

[Driver]

Im talking about if u wana get sum decent power out of it..

[gatty]

under a grand, wtf how?
