Fitting Gt3040 On Rb25.....

[sinistaGTR]

hey guys,

my gt3040 rocked up 2day and i put it on my manifold but it doesnt quite fit nice...its hitting on the rocker cover by a little bit so do you have to grind/sand a little bit away.....

would be much better

Thanks

what manifold?

[sinistaGTR]

dounno my t70 fit on ok just the angle of the gt3040 is different

lol have come across this problem before and i have seen some VERY VERY dodgy fixes before how ever found the easiest one was make a cut under the t3 flange.. bend flange down and weld up if you get wat i mean.. just leavers the flange away from the rocker cover a bit

by far the dodgiest fix ive ever seen for this was using 6 12mm spacer plates between the head and the manifold how ever didnt want to tell the moron that chose to go this way wat the effects would be on the way it will perform.. but how ever.. the guy is a f**kwit and its still running around with the 'spacers'

[sinistaGTR]

do you mean the flange on the manifold i would prefer not to cut my manifold

[rb26s13]

just under the flange were they all come togegether show a pic of your manifold and i'll show you were

[R31Nismoid]

comp or turbine housing hitting?

and by how much?

got pics?

[rb26s13]

im guessing the comp housing r31nismoid.. cant remember wat brand of manifold it was but have come across it a few times

[FORZA-MOTORSPORT]

I sell adaptor plates to suit stock manifold, they can run an external wastegate too

[Craved]

umm for the housing to hit the cam cover, it must be a highmount.

[r33_racer]

Quick question mate, have you tried rotating the compressor housing so it wont hit the rocker cover? I think you will find you just need to turn it around till it misses and you have sufficient clearance. Normally you would turn the housing around so the outlet is facing down towards the chassis rail.

[sinistaGTR]

ok its a high mount, the comp cover is hitting, i turned the comp cover around last nite so it was facing the strut tower as thats where my cooler pipe runs already i will ger pics tonight.

Umm... high mount would lead me to believe that this isnt a stock anifold application

Oh, and this isnt the For Sale section... so dont advertise your "wares"

If its one of those cheap XS-Power high mount manifolds, i wouldnt be surprised, you will find that there is over 1.5mm bend on both the head side and turbo flange, as well as the turbo flange being at the wrong angle hence why your turbo is hitting the rocket cover! If you try bolting it on you will also notice that number 3 runner hits the exhaust stud. These manifolds are crap half made of mild steel i.e the flanges and the runners etc made of stainless hence why they crack, i hope you dont have one....ow and i forgot but the bolt holes for the manifold most probably will be out too you will have to grind out the holes on the manifold.

its ok i managed to figure it out it was dark when i did it last nite. it sits very very close to the engine i had to move the comp cover round a touch and its sweet as. and as for my manifold ive had it on there for a while now and it works fine and every thing lines up, i had my old turbo high mounted aswell but i blew that one up.

[R31Nismoid]

i was gonna say "most" are ok.

the old turbos comp housing should have been the same as the one you have now wouldnt it?

[sinistaGTR]

the old one was a bit different shape, they were both.7 but the one on the t70 seems a bit smaller only by a bit but...... oh i cant wait till my car is actually goin but......lol
