hey guys,

been a while since i have posted but i think i have a real crappy problem...

ok..

i havnt drivin my car in weeks which is an r33... and this morning i thought i would start her up and let her run for a bit...then take her for a wash and a little spin.. i let her warm up checkin all the fluids first and so forth.. everythin was just as i left her... and as i backed her out of the garage i heard a weird rumbling sound coming from the high mount manifold... so i jumped under the bonnet and gave the car a rev.. and man was my car loud!!!!.. so i checked all connection for anything suspcious until i came across the devil!!..lol... i noticed that there is a hole (about half the size of ya pinky fingernail) in the manifold... its just under where the turbo sits on the manifold along the pipe that goes to the external gate.. WHAT DO I DO???

is there anyway to fix this with the manifold still in..or does my whole setup have to come out!!.... this is the third time this yr ill have to bring out the turbo!!... so sick of it.. anyway anyhelp would be greatly appreciated.. from where to fix it to a shop where i can buy manifolds.. btw from the s/e suburbs if that helps..

You might be able to have it welded, totally depends.

You will need to see someone who can weld DECENTLY and see what they say.

Poor man pays twice, cheap china manifold is now almost worth what a decent one outright is :(

only problem with probably 90% of stainless manifolds available atm is they are all crap...wall thickness too thin, design is piss poor. If you modify them and brace everything they will last a while, on a road car that is. But the time, money and effort that goes into pulling it off every 6 months because the flanges have warped and cracks have formed and need welding makes it worthwhile to actually spend more and buy a descent one that you wont have to touch after its been fitted the first time. On the race car i got sick of pulling it off and repairing it and putting it back on every 2nd race meet.....discovered 6boost manifolds and have never had an issue......ever.

Nothing wrong with stainless.

My old Nismo stainless manifold is almost 20 years old (now with a friend) and its never cracked once :O

All about the quality of the stainless, thickness and design.

most stainless manifolds and every stainless manifold ive seen on the market are made from 306 and 316 grade stainless and this is a very poor grade to be making manifolds from

trust would have to be one of the worst when it comes to big brands, ive seen so many of there manifolds crack

X2, stainless isnt a problem, infact i've noticed recently alot of race cars (i've ben lookin at US ones) have been using them, but obviously thicker/of a higher grade

full race use CAST STAINLESS for there manifolds which are alot stronger compared to most of the junk stainless manifolds out there

personally i would still go for the steam pipe option

LIFE TIME WARRANTy :)

by "bracing" the pipes - are they little bits of sorta U shaped metal welded on right at the ends of the flange? just wondering, i just picked up a new manifold with these things on it - i guess by no means is that a garuntee of quality - worth a try though.

yeah the U shaped bracing is standard on most stainless manifolds

nah ones i saw were hand made from pipe and steam-pipe-esque bends

although yes i too would opt for actual steam pipe

Yeah we had a stainless SR highmount gate flange break off...right in the middle of the pipe, and on top of that while it was broken off, the turbo still spooled up to a bar! (previous boost control issues)

The material was rubbish. So was the design. Was bought from a reputable retailer too.

Bought one from Just Jap, havent tested it as yet. Its twice the weight too, should work good.

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
