I just bought a high flow turbo which I was told was a genuine bolt on job. Being fairly new to the scene I thought that bolt on meant it was pretty much a straight swap ie. no stuffing around with oil and water lines / fittings. Instead I get a turbo which isn't even close to being a straight swap. None of the stock oil/water lines match up and the turbo needs to be "clocked" so it matches up with the stock air inlet.

These are all questions I should have asked before I got the work done, isn't hindsight great.

Anyway, I just wanted to see what other peoples ideas of "bolt-on" were.

Cheers

well bolt on is.. straight on no mods.. custom is doin something different to make it work..

when u have to get new lines or something like that u cant classify that as straight on.. ur mucking around...

Tis bolt on if your engine can handle the turbo upgrade..

a turbo that requires some bolting requirements

LoL..

Is the HKS GT-RS kit with the oil water lines and all fittings and shit.. is that classified as bolt on? cos everything is designed to fit like the turbo and oil n water lines in the kit?

i class it as 1 that you attach with bolts, rather than with say, glue or zip-ties.

but seriously, i would class it as oil and water lines screwing straight in, even if the oil line has to have 1 of the fittings drilled out to let more oil through (e.g. a slide highflow). and most importantly that it bolts up to your manifold.

Bolt on = bolts onto the stock gear.

Manifold, dump, intake pipings

If you need to mod a oil/water line, big deal. Its really not that hard.

I wouldnt count oil lines depending on the type of turbo (covered further on)

As for the turbo being "clocked" what you do mean?

One of the housings rotated? If so, thats pretty much gonna happen on any turbo as no-one is going to get it perfect for your car

Also depends what types of turbos (as i said earlier) ie Bush --> Ball bearing and vice versa.

If thats the case where your changing from one type of turbo to another (and reason for the oil/water mods) then its a bit of buyer research aswell as the seller IMO.

Two way street on that one as an owner you should really take a little interest in what they are purchasing :(

Can you give more details?

Type of turbo you had, type of turbo you have change too? etc?

Would kinda help us to give you a better idea maybe :)

The product is a direct competitor with the GCG highflow. Stock turbo to ball bearing highflow.

It was explicitly stated that no modifications to the stock lines were required. The only change needed was to change the banjo bolts (not the entire fitting, just the threaded part) because the thread on the new core was different.

The reality is the oil and water lines need to be changed, the oil drain needs to be modified and the wastegate actuator needs to be modified. The fittings provided look like they are designed for rubber hoses and as such, are completely useless.

I personally wouldn't call this a bolt on affair.

Thanks for the input.

if that is the case then it isn't a high-flow, it is a whole new turbo. it obviously isn't using the stock housing, otherwise it would just bolt back up.

i'm not aware of any other high-flows that use ball bearing other than the GCG. i know slide's are a bush bearing and it needs the hole in the banjo line drilled out to let more oil in.

      Quick Lifts? Anybody got one?

      By PranK · Posted

      The jack pad placement always had me scratching my head. I only have a small section to work with on both the E90 and E70 (and insert new project car here ) and I could see lining it up to be a bit of a bugger. For me, the E90 is just too low and needs small ramps and then the front centre jack point is a bit tricky to line up (it's half way down the subframe and about the size of a tennis ball, its really hard to see unless your head is on the ground), so I definitely like the idea of not having to do a multi-stage jack and just sliding these bad boys in under the sides. There's only one small point at each corner, so I can't jack AND add a stand on the same corner. Or, maybe I can and I'm too nervous to try. 😟

      Is this not the biggest deal of all? I was hoping the whole "will slide under cars with skirts etc and lift evenly quickly with minimal fuss" was the entire point of such a device?

      Yeah I've got one of these, Quick Jack not Quick Lift, but your link looks like a good copy For me, it's better than no hoist, but it is definitely not as good as a hoist  It lifts the car about 60cm which is a nice working height compared to regular stands and it is only under the sills so it doesn't get in the way like regular chassis stands do.  No need to use regular stands, it has a safety lock on it. On the down side it is really heavy/unwieldy to drag into place, and you have to place it after the car is there (no option to drive the car to where the frames are. You need to try and line it up with the proper sill points which is hard as it swings up in an arc and there is surprisingly little adjustment in the distance between the rubber pads for different car lengths. Not a big deal, but in practice a jack + stands is probably quicker. Also there are hydraulic lines to each side and you need either a 240v or 12v source to power it depending on which option you have, I use 12v as I always seem to have a battery around.

      Finally addressing my catch can and oil setup Plan is to do as much as practical without having to remove the motor or pull it apart. (no back of head to sump drain/breather or oil restrictors) First step is a set of full length baffle plates from Hypertune and a Tomei cam cap stud kit. I could probably have laser cut and bent up my own ones but this took any guess work out
