Hey guys in the market for an R32 and have found a mint one, but just wondering about the RB20 silvertop.. is this the stock engine for the series? Car is 1989 R32, with an RB20 silvertop obviously. Is the silvertop any different from the other R32 engines? And if so does it have potential... with a realistic budget ofcourse.

Cheers.

No that isn't the stock motor only later model 32 gtst's had the silver top NICS Rb20, it is a good thing though as it is better than the red top ECCS Rb20 which is the stock motor for the car. The silver top has bb turbo and rated at a bit more power.

As for potential Rb20s are good for stage 1 mods like exhaust, bit of boost, ECU, gives about 160-170rwkw.

Turbo, intercooler, fuel pump, AFM, injectors gives 200+kw but they lack torque and people usually dont bother and dump them for rb25s

hey mate,

from what i know..

the rb20 has been around for quite a while now. started out inthe r31 in japan as an rb20 redtop NICS. then, after some development, along came the rb20 redtop ECCS version, also in the R31

the r32 came out with the rb20 silvertop ECCS version. all r32's have the rb20 silvertop version, all have a ball-bearing ceramic turbo, all are intercooled etc.

they are a great engine for modifications. now remember that they are only 2L in capacity, so when the turbo is "off boost" they lack the ability to get the car moving like a commodore would. but, after say 3000rpm, they really get moving.

on a manual car, with about 2000 spent on an exhaust, boost controller, and maybe a front-mount intercooler, they go like a cut snake.

Nope all r32's rb20's were the silver top. R31's had red tops. NICS were the old red tops, ECCS the silver top.

WTF are U jabbering on about? ALL R32 GTS[t/4]s came out with a silver top (RB20 ECCS).

Hmmm yeah that would be cool bubba.. going to have a squiz at the car tommorrow arvo.

Well i'm not so worried about all about power... the car seems to have ALOT done to it.. what i'm worried about is that he told me it has 'alot of lag'... it has a Garrett T-04 turbo fitted to it... I'm concerned about a mismatched turbo... full boost isn't until 4500 so i'm told..

Anyone know of this turbo being fitted to an RB20?

Cheers.

sounds pretty big.. i get 13psi through my stock 20 turbo by 3500rpm, stock is reasonably laggy as it is.. taking gaps in traffic is chewing my tyres :no:

is the engine stock internally? coz the turbo would probably go well on a 25 when the 20 dies :P

Yeah its stock internally...

but add ons.. has secondary injectors, Greddy rebic fuel computer, HKS ext wastegate, aft manifold, 3 inch turbo back exst, FMIC, GTR fuel pump, EBC, remapped ECU..

Could be a hard one to keep on the road i'm thinking..

Sounds fun! the turbo/manifold/gate should bolt easily onto a 25 and the supporting mods such as exhaust/fmic/fuelpump/ebc are done so all you would need is an RB25/ecu and it would be even MORE fun! Oh and maybe some injectors depending on how hard you want to lean on it :)

      boost source Size Garrett gt28 gen2

      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.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      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.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      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

      Spotted on the street....

      By Rezz · Posted

      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.
