That won't be for a while though, I'm sick of working on it now. Link to comment Share on other sites More sharing options...

I went to try the two I've got a few years ago but couldn't get the nuts (or bolts?) undone from the housings so I gave up. My boost was similar to yours with 18 in the mid and around 14 up top, punched out cat though and the usual bung removal otherwise stock exhaust and it sounds like a sh*t diesel truck when idling lol Link to comment Share on other sites More sharing options...

I hated it, only time it was acceptable was on load. annoyed me for cruse especially since being a family car. I fitted a fg turbo manifold and a 4inch xforce dump. I had to cut and reweld the bottom piece of the dump, I feel as it was touching something or pointing the wrong way I wanted. I cant remember now it was many years ago. But it goes into a 5inch cat, then 3.5inch pipe to a hot dog and still the standard 3inch rear as ive been to lazy to make one. but its on my list, but in current form it sounds good on noise and pretty close to stock on cruse. 1 Link to comment Share on other sites More sharing options...

I have most items for the usual mods except for the dump valve for the exhaust as I don't need a 3.5" even though I'd like a full system Link to comment Share on other sites More sharing options...

Here's a tip for making the car quieter, use an fgx sprint cam timing map and it'll be all kinds of quiet. 1 Link to comment Share on other sites More sharing options...

Now I can stall it up in 2nd gear, 3500rpm, full boost which is around 16psi and let it rip. It goes ok but it's probably just as quick using first gear. Nothing a bit more power wouldn't fix though 1 Link to comment Share on other sites More sharing options...

No doubt there is something there but the seat of the pants was lacklustre. Pretty sure I can have my custom four inch turbo back system installed in a few hours. Gotta cut an shut a bit of it but the parts are here and I'm getting antsy. Hopefully it's not too loud lol 1 Link to comment Share on other sites More sharing options...
