Yeh. I reckon one of those bad boys and a good ecu with good traction control and it would shit all over alot of other cars. The supercharger guys told me of a hill climb car they fitted a supercharger to over in Perth somewhere and it was turned into an animal.

Lol workshop tomorrow mate! Engine and gbox are going back in and then start hooking everything back up and finish exhuast system and fuel system. Then test. I had to get the head reco'd. Valves were not sealing. Lol lucky I did a leak down test before putting everything back in the car! Pretty much wasted a week there though ;)

Speaking of exhaust system i/my brother might have to make a custom 3.5" cat back. i cant find any that are close to/are legal DB wise (or would be with a small amount of modification). I want to try and get something that will allow 400kw and still pass an exhaust sound test.

Keeps the neighbours off my back and avoids any unwanted attention (not that there will be much to pick on with the thing engineered)

think positive, better that you find it now than when its all back in there.

That's why it's good to have sympathetic neighbours haha I leave the turbo timer on for 5 mins at 4 am and they don't care at all

There was a guy somewhere out west who was making exhausts for about $1200, he would ask how much power it needed to flow and then the db it needed to be. It was guaranteed to meet those specs. BenM was talking with him years ago when he had his White GTR. Don't know if that helps?!

you wouldnt happen to know any more specifics on the guy?

Not off hand sorry

It would take a fair while to search for his name I think, send BenM a pm, I'll have a look tomorrow incase he's forgotten the name

Yep id be happy with that!!!

How was it in the top end?

Its so frustrating trying to get the "perfect" set up. I want to get mine coming on about 1500rpm sooner, so i think changing cams is the go. Makes 400rwkw at 5000rpm now.

Id hate to be chasing something like a 180sx with a 3L and a super responsive turbo through hills though, there's just no chance of catching something like that haha

Shithouse in the top end, had the limiter set to 6800 and from 5800-6800 it went from ~250rwhp to 90rwhp :)

I can tell you though the little 32gtst with the 3L and 25 turbo was ballistic through the hills, highway was awesome too, never needed to drop it back a gear, just roll on in 5th :)

is that with a aftermarket computer or the standard one? wouldnt mind getting mine going on the standard one for the moment then putting the aftermarket one in abit later. can do it all now/whenever i want if i really want but would love to get it running again without spending all my money on it.

has anyone used the standard ecu on their rb25-30? sorta worried about doing that coz it might be in the rich maps and wont allow the new motor to bed in properly from running rich. piston rings and glazing the bores and crap like that

I ran mine untuned on the RB20 ECU for about 4 months, I just didn't rev it over 5500-6000rpm because a) afm was maxing and b) turbo choked the engine up.

It did actually mean I was slower than a standard 32 because I couldn't rev it to 7500rpm, some 3.9 gears helped that.

i got a 3076r 0.82 on a 26/30 with stock rb30 n/a pistons, stock 26 head and stock cams, it makes 21psi at 2900rpm in 4th on flat road, though its hard to tell exact as i cant log the boost/rpm to double check. It does die in the arse abit up top but i think its due to cam timing which i still havent bothered to sort out. Its making a lack of power due to the same reason but just doesnt have the feel of a bigger turbo i am used to. The whistle of the thing annoys the shite out of me too, i hateeeeee it.

Not off hand sorry

I went and had a chat with the local exhaust shop as i needed to get a euro 3 cat for the emissions test, using a rough guestimate on required materials i can make my own custom 3.5" catback with two large mufflers for about $1000. Thats assuming i can fit decent sized off the shelf mufflers under there.

So for about the same money as a jap catback i should be able to get pretty close to legal DB. :)

lol im at work and its lunch. If only I was at home and working on it..

Side note, I got to briefly speak to Mike Vine at the speedway saturday night and I told him about my project and he said they did something similiar but had to run two throttle bodies because apparently there will be abit of lag in the time it takes to fill everything after the supercharger to the plenum as its alot of volume in vaccum and takes abit of time to fill.

The old codger scared me with the lag part! Making me thing I should have just left the throttle body were it was..... DANG!

    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
