Hey...i recently blew up my engine, in my R32 GTST...too much boost and it was running too lean...looks like it blew a hole in the piston...anyway its stuffed

So rather than fix it...i picked up a half cut for CHEAP($1600) with 70,000km's on it and completelly stock...which happened to have an auto gear box in it

...So, will the new engine go straight onto my manual box...and will the ECU out of the auto be any good for a manual...im asuming there the same

the reason i want the other ECU is cos mine had been tuned by Mines in japan and i wanna start a fresh cos the other was maped for japanese fuel etc...

Also is there anyway to convert japanese dates to ours...i got stuff in the glovebox which says 15/3/29

thanks

Note: its easy to run more boost...but remember that u will need more fuel...or u r car will end up like mine...and its not fun :D

Is there any way to re-map the ECU here in Oz?

Also, just a few quick questions, i'm about to wind up the boost in my rb20, and wanted to know a safe level. What were you running when it blew?

And with your half cut, did it come with the headlights? Coz i need both left and right headlights and indicators... If you have them, i'm willing to buy them off you...

Cheers. Matt.

i was running 12-13psi when it blew....so if u do wind up the boost make sure u have enough fuel going through it

my halfcut only came with headlights...but i wanna keep them for mine as they are like new :D

i bet just the headlight on their own would cost about 1/4 of the price of a half cut

hey..

need help..

i'm having engine problems while i was cruising at around 30km/h...

my mech said my engine blew....

the engine looks perfect externally...

n he adviced me to convert the engine rather than to fix it...

what advice do u guys have n how much would i be looking at if i were to fix it n to convert the engine..

thanks....

JO3, sounds like u r in the same boat as me

is u r car standard...if no what mods have u dont

wouldnt hurt to check u r fuel pump

It was cheaper for me to just buy a half cut than it was to fix my engine...only $1600 for a auto R32 GTST thats done 70,000km's

that way u have heaps of spares and u will be all set

Im just swaping over the engines myself...cheaper than a mechanic

do u know what exacilly went wrong with u r car???

mine was running too lean and blew a hole in the piston

I hope this helps!

Its either buy the front cut like hawker stated or outlay another 500-600 for a standard RB30DET rebuild OR slap forged pistions and shot peened rods in to the RB30DET which will add around another 2k on top of the 2300 for the standard RB30DET rebuild inc. the RB25DE non-vct head.

Its really not worth going the RB25DET as you have to do the whole ecu thing, change plenums etc etc and it doesn't look stock.

The RB25DE Non vct head uses the Rb20DET plenum, exhaust manifold & injectors & ecu. Then chip the ecu to suit the setup and yoru hauling arse with the std. terd on full boost under 2k.

Or a RB25DET turbo making 200rwkw and full boost still under 2k.

Or 300rwkw :D

No more worrying about the Auto V8's off the line and having to get the rev's up quickly incase they gun it. :D

Only if you keep the bottom end stock and leave the head as it is & do the labour of fitting the motor your self.

i.e

RB25DE Head - $750

RB25DE VRS Kit - $275

RB30E Short Motor - $150

RB30E Rebuild std. Internals, Nissan bearings, bolts & origional pistons, balanced - $1100

Waterpump - $80

Coolant - $60

Oil - $60

I've rebuilt the head and had it ported polished, 3 cut valve job, comb. chamber cleaned up and polished etc. The head work cost all up inc part $1100.

Then you add the price of the RB25DE head on top of that which I picked up for $750 from Adelaide Jap.

If you rebuild a RB30E short motor with standard NA pistons & balanced I was quoted $1100 from City Dismantlers. I then decided against and decided on forged pistons, shot peened rods, o-ringed block.

This has bumped the price up by around another 2k.

My RB20DET manifold bolts straight on and with the RB25DE VRS kit I bought for $275 it has both plenum and inlet manifold gaskets, head gasket, exhaust gasket, cam seals, rocker cover gaskets, valve stem seals. So thats the top end gaskets done.

It is possible to use the RB20DET oil pump but that is the next decision along with which ecu to get. I was told to budget on 4.5-5k for a Motec or Autotronic from Turbo Tune so i'll throw that Idea out the window and stick with the AP Engineering PowerFC that will be heading over from Greenline for $1398 inc. postage & gst.

I dont know what to do:(

Maybe i should start reading the RB30 thread:(

There is a slight noise from my engine bay on start up... im hoping its some engine ancillary:rolleyes: but the noise warants attention.

I hope the engine is ok for a few dyno pulls with the new turbo. I want to see what a RB20 (albeit perhaps a worn RB20) can muster with a nice turbo setup and a healthy dash of boost.

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
