Hey guys,

Got an RB26/30 and a big single turbo - the bonnet is so close to shutting but just wont shut!

What have you guys done to get around that?

Im trying to avoid spacers, was wondering if there's a carbon bonnet or whatever thats got great clearance?!?!

Cheers :P

Well yeah guess i could, but would really rather not :D

Good suggestion though

Translation: Shit didn't think of that.............. :)

Were is it hitting? Timing belt cover or the turbo.

If you get a genuine c/f bonnet it doesn't have the support frame, as it is very strong/stiff on it's own. I have a full c/f bonnet made by Custom Carbon (currently not fitted to car and at the mechanic's w/shop), it consists or 3 layers of carbon and resin, that's it, no fibre-glass, etc.

spacers are the only way to go...

on the xmember or on the bonned hinges

Looks that way unfortunatly

I rearranged my piping and put 10mm spacers in the hinges.

Cheers :D

Long time no speak!

lol, it was suggested by the mechanic and yeah - not a fan of the idea

Hitting turbo, im going to get prices on carbon over the next few days and if i go down that path (currently spacers is the go) ill spray it white to match

i dont know if anyone has thought of this, but any one thought of using LD28 engine mounts instead of hacking holes in bonnet subframes?

this was suggested from a retired mechanic who helped with my hilux rb30 conversion.

DIfferent mounts cant fix the problem, as the sump is about 4mm from the crossmember

then theres def something wrong my rb30/26 has 28ml of clearance from sump to the nearest piece of crossmember/steering rack....... and still have room for the 50x50 ml overkill strut brace over the top of the motor.

Im guessing your isnt AWD, we have a diff/adapter plate to fit under the motor as well

That must be a HIGH high mount manifold or is the turbo THAT big?

Cheers

Here's a pic :)

It was taken a while ago when it was dummy fitted together and before anything was done to the sump

Hey Steve!

Just occured to me now: WTF are you always bringing the auto supra to DECA. HTFU and enter the GTR, once it's up and running :)

PS: I want to see pics and details :thumbsup:

lol, the supra does so well down there though, 3L, small turbos - great response :)

Im organising a car trailer for the gtr so i can bring it to the deca masters ;)

Ill show you around it when i see you next, take it for a 'fully sick' lap of shepparton, basic details are;

3l bottom end

2.6 head with a little bit of work done

giant turbo

built bottom end

dry sump

triple plate clutch

talentless driver

ap racing brakes

tein suspension (got to get swaybars sorted asap)

there's more to it but thats the rough details :)

+1

Is it RWD?

lol, I did predict this happening months ago when you showed pics of your worlds highest high mount. I would look at possibly a more suitable turbo/manifold combo which will not only clear the bonnet but make the car nicer to drive, but I know you have your heart set on the mack truck version. in which case I say just go the spacers and be done with it. it's the easiest cheapest way out of this problem.

lol so true. Well its all a stop gap to be honest, got a spare rb26 at home that im going to get built and do the dry sump thing with aswel. It will have some -10's so clearance isnt an issue once i get that one back in

pffft bonnets are for sissies :down:

lol

Damn that's a huge turbo! :wub: How many Hp?

I wanted response with my rb25/30 combo, so i fitted the smallest recommended turbo GT3076R; also a fully built engine.

Love it! :ermm:

Can't wait till the next DECA, will be awesome.

How many hp? Oh, its got enough :whoops:

Ill see you at the next one :whoops:

Have you got it in the car yet?

    • 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.
