GT4 COA and Fuel pump mods pics ! Fri, 26 December 2003 08:18 Go to next message
Well its done - i got my cold air induction up and running today Smile - and also ive taken a pic on which fuse needs to be jumpered to get the 13v fuel pressure thingo happening on an St185 Gt4

this is how it was done - in a nutshell .

First - jack thecar up - remove passenger side front wheel

then - remove the plastic shrouds under the guard - taking care not to break it . - the main ones BIG - it leads all the way to the front of the car.

OK - you now should see this !

http://home.iprimus.com.au/utahraptor/gt4_pics/gt4mod1.jpg

that ugly big box is the induction resonator - or something - better known as a total waste of space and plastic ..

Notice on the up theres a pipe leading off into the engine bay !

thats the one were liberating for the cold air induction !

To remove it there 3 bolts - one below the battery , one clearly seen from in front of it that bolts to a metal brace to the fender - and One up above that - behind the electric motor for the pop up lights .

This last one in particular is an Arse to remove - ALOT of fiddling to get into it - but it can be done by raising the lights , then using a 10 mm socket and extensoin - you can make it loose enough to take off with your fingers..

After its out - youll have a BIG space under that arch - to pipe up air from outside the car .

http://home.iprimus.com.au/utahraptor/gt4_pics/gt4mod2a.jpg

Pipe measurement for the opening is 50 MM - so you can either use flex hose and clamp it on as shown - took me 10 mins to do - and cost 20 dollars for the flex hose from repco - or use PVC piping and make it a little more solid ..

I may use a combination of both as soon as the other bumpers on - to use the brake duct on the passenger side as the inlet.

You can use bigger diameter hose if you want - but that will require opening the hole in the side of the engine bay up more.

Lastly - if you want to use the 13v constant fuel pump voltage mod - as mentioned on the gt4 faq's - this is the fuse you need to jump - Pretty simple huh ? though READ THE ARTICLE FIRST - just incase yours is different to mine !

good job dude, it's amazing how much space that opens up isn't it. Yeah I did mine with 65mm PVC but the box that's thats in an ST165 is a little different to that so you don't need to make the hole in the panel any bigger to fit larger pipe.

im sure a 65 would fit though for now it was easier to clamp the 50mm on the outlet ..

now that the hunk o useless plastic is gone - i can get in there and experiment

still wondering if the 50mm pipe is too " small "

so far no hitches - the car seems to accelerate alot smoother ( this also could be due to the exhaust ) and its using less fuel it seems - both positives

its also no noisier on the road Smile

if it wasnt for a small shiney piece of flex pipe cable tied to the grill - you wouldnt even know its there

I did mine out of 100mm PVC pipe but that obviously involved grinding out the hole on the inner guard so it would fit. 20 minutes with a trusty die grinder, a bit of paint and a rubber edge seal and it's all sweet again.

DAMN THAT LOOKS GOOD....
U know how u took off the resonator, what is the clamp actually holding onto???

Would it be almost the same for a 162?

Regards

Nice work!!!! Very Happy

Hmm... Interesting.

You are still using the standard airbox etc are you?

Have you got your GrpA front bar on yet? everytime I remove the splashguards it stuffs up the mesh on the GrpA bar and it takes me a couple of weeks to get it all lined up sweet again...

im trying my best not to cut/grind anything - I have a feeling a 65mm one will fit - though it would require removing the inlet thats there and the section of ducting that goes behind the light to draw air from there ..

How do you find the 100mm ? is it going into the stock airbox ?

Pics would be sweet to justen Smile

As for mine - I slicd a small nick on either side of the plastic duct seen up top - then fed the 50mm pipe into that - then clamed down on the hose .. pretty easy - though im not 100% sure if its the most effective way of doing it

plusses here is it all looks stock as a rock from the engine bay side of things . And yes - its straight into the stock airbox for mine

As for the grp bumper - ive got the last section of mesh in production ( ie im having to make it ) Its not on the car as yet.
( want to get all the bits ready so it can just be painted and bolted up in a day or two )

I just need to figure out a effective way of mounting copper saddle clamps to mesh - outside of riveting ..

Epoxy/araldite ? or solder ?

Solder may work best - though its copper to alum mesh ..? Ideas ?

Hey Stuart Do you mind if I do a quick hijack of your post and chuck some pics up here af an ST162 setup, or is that a nono Rolling Eyes

Justins actually just feeds air to a pod filter he has sitting to the side
