Fitting my front mount

[Dave_GSR1.8]

I know this has been done to death but I thought a few pictures of the fitting of a front mount to my stock GSR might be of interest to those like me who are new to all this. Nothing too clever, just a cheap XR6 FMIC mounted up to the stock pipes.

1) initial mounting to get best position



2) Close up of the connections to the stock intercooler pipes



3) Final fit



4) and with bar reattached

looks good mate! i thought it might have been a bit low but seems to sit inside the bar nicely.
hows boost levels now? pick up better?

Yep. Great job. Stealthy as

So having got that done the next thing was to get a tune done by another tuner (not happy with my initial tune, not because it was a weak result, but because the tuner did not try to find the problem). See my initial thread in Intoductions, "Hello and a story of the mild mods on my CC GSR, so far"

Anyway, second time round was a good result, went from 104kw atw to 131kw atw, I'm pretty happy with that as still running stock turbo, injectors and AFM so I have taken it as far as I can without upgrading turbo with supporting mods. Given that I have run out of budget I can only do small stuff for a while, next is the camber adjusting bolts on front struts, to go with rear sway bar and castor adjusting bushes already fitted.

keep an eye out for the evo stuff it comes up cheap from time to time and collect it over an extended period. you wont regret doing it

Thanks guys, yes, just fits inside the bar, the low pipe required a fair bit of trimming to get it to fit but all invisible from the front. The bar is a bit rough where I have trimmed it, I will clean it up with filler etc when I get some time. I tried an angle grinder (big disaster!), jigsaw (uncontrollable at crazy angles) and finally found one of those new vibrating cutters did the job nicely.

Pick up is dramatically better, upped boost to 14psi, now I think it is a moderately quick GSR! Not having driven or ridden in an EVO I can't tell for sure, I'd like to to think it was better than stock though.

Watch you dont bend the rods. And check for boost leaks letting all that boosting air out.
You should run it on the strip. Should be way better than my 'nearly' 100mph.

Would like to see a ecmlink log 3rd gear pull from 2000 rpm up. Just to compare with mine.

 

[Dave_GSR1.8]

Thanks Jack, hopefully I won't bend anything! From what I have read it seems that 14psi is OK on these engines, lots of discussion here about how much boost it will take, 14 ok, 15 ok with good tune, 16 -17psi, pushing it but some get away with it and a timebomb any higher...

When I fitted it all up I managed to borrow a beading tool so was able to bead all my cuts and I tightened the bejusus out of all the new clamps.... I should do a leak test though, just gotta make up a tool.

I will try and get some logs for you over the weekend if I can get all the chores out of the way (you know, mowing, putting up new clothes lines etc etc !!)

One thing that came out of the tune that I thought was interesting was the issue of power loss through the drive train. I have often wondered what this is on the GSR, well now I can speculate a bit. I have seen figures of between 25 and 40 % suggested. Now if I'm getting 131kw at the wheels this means that a 25% power loss translates to 174kw at the flywheel. This is believable, if one assumes a 40% loss this means that there would have to be 218kw at the flywheel, which I don't believe, I can't see my 93T making that sort of power on the mods I've got, so I reckon 25% loss is a good upper bound on powertrain losses, from the numbers I have.

BTW, anyone know what sort of power (roughly) I can get with a TD05-14b + EVO1 injectors and AFM (already have FMIC, ECM lite chip and 3" turbo back exhaust)? I have gone through the forums and don't recall seeing any specifics. Just idle curiosity but fun to speculate !!

i made 180fwhp on a td04 or 5 can't remember which turbo was in at the time of dyno it boost creeped to 15 psi was still running std gsr injectors afm and ecu so i don't think around 180flywheel kw is out of the q for awd

 

[4piknup]

I still say 30% loss on awd.

 

[ENGINR]

Very neat install job and completely sleeper - well done.

 

[evo-gsr]

Agreed...looks good mate.

 

[CYBORG-X]

I made 110kw on stock gsr setup even exhaust was stock, but it had a hi-flow turbo at 10psi, re-shaped manifold and dump housing only.
And i made 138.8kw on gsr with 14b at 16psi, injectors, afm, ecmlink, exhaust, evo cooler, cam gears, larger tb.
Go figure...

 

[Dave_GSR1.8]

That sounds right, I'm on 131kw atw (well according to dyno anyway) with ecmlite, exhaust, XR6 FMIC, magna TB, everything else stock, TD04 at 14psi (too chicken to boost it any further). I've come from 93Kw atw bone stock, with leaking sidemount, so I am pretty happy, except I am an addict... sooooo starting to assemble parts for turbo upgrade, might take a while though...
