Similar speed worked OK on most other laps in the rain, just requiring a dab of opposite lock to keep things sweet! I just turned in too late and aggressive on that one, and it all went tits up very quickly!

In other news, we just bought six part worn yoko A048's on ebay! so that's next years tyres sorted
 
Hi prawn, i know your the guy to go to for advice, iv been offerd two lcr hubs for £70 and the two wishbones for £70 and £50 for the lcr quick rack, is this a good price for 2nd hand in good condition and how easy is it to fit all of the above myself or how much do you think a garage should charge? Thanks for any help and advice.
 
Winter is here, and it's miserable!

Now that I've got the Rotas, I've been able to take the TT rims and use them as winter wheels on the daily.

I managed to pick up a set of fairly budget tyres, brand new on ebay, for just £101!

I went up to my mate Bruces last night, and fitted the tyres, Bruce was busy, so he showed me how to do the first one, then I did the rest myself, quite enjoyable actually :)

So, here it is, the daily, on it's winter rims:

17x7.5J TT 6 spokes, spaced 17mm front, and 20mm rear giving ET15 front, and ET12 rear, with 205/45's

Pretty happy with them, they look fairly good I think, it's a bit different, and it's all good and legal now for the winter months.

With that done, I set about curing the nasty rattle I've had in the exhaust for months, I took a gamble on a toyosports exhaust back in April, and to be honest, it hasn't paid off, as it developed a rattle within a few months. I couldn't send it back, as I'd had to modify it hugely to fit my car anyway.

I tracked the rattle down to being inside the centre box, so today I whipped the centre section out, and cut it open:

With the flap opened up, it was pretty apparent what was causing the rattle!

Cheap nasty **** :(

Rather than try and weld the tube back into place, I decided to just rip it all out, so I emptied the box of all it's cladding, and the broken perforated tube, and welded it back up again. excuse the awful welding, I've not used the welder myself since last christmas, and welding thin stainless with mild steel wire is not something I'm good at!

Welded up, and linished down, I gave it a few coats of VHT silver paint, to stop the mild steel weld rusting on the stainless box:

Refitted it after going into town with Tori, and all is well. the rattle has gone, the sound hasn't changed that much, so I'm happy.

that's half a day spent on the daily this quarter, so that'll do! Will get back to the track car again asap :)
 
I'm really liking those wheels!
It's mad how wheels change the look of a car so much!!

Mine are different to yours westy! These are the ones I had in silver for years, then in orange on the track car, then finally in black.

Pats right, it's amazing the difference wheels make, here's a comparison shot:

Are you sure our 17s aren't the same? They look the same to me but I'm not a wheel whore like you :think:

It is amazing what a set of wheels can do to a cars appearance. Also the contrast of the silver S4s to the black TTs makes such a big difference too!
 
definitely not the same mate, yours have a kinda sharp lip at the edge, whereas mine go smoothly into the edge of the rim,

here they are in orange many moons ago: you can see the shape difference compared to yours here:

17" ronal TT off the mk1 TT i think?
look loads better with out the centres in! been trying to find some plugs for the smaller centre but no luck as of yet
 
In a slightly different move to the usual, I've just bought myself a small port inlet manifold to replace my large port!

It turns out, my original plan to fit AUM injector seats into an AGU inlet manifold wasn't going to work, due to differing thread sizes. I'm sure this COULD be overcome with some machining, but this isn't something I wanted to have to do at the moment, so I decided to try another route. Big thanks to tufty for checking this out for me on the AUM/AGU sizes.

I figured that Welly and Tufty have been running small port inlets on large port heads, seemingly with no adverse effects, so I decided that the easiest way to fit my genesis 550's was to run a later style small port AUM/AUQ inlet.

As per Paul and Welly I'll run a phenolic gasket and port it across the transition.

Injector fitment sorted, and all for £35 :)

Should have the VR6 MAF housing sorted now as well.

Having a massive sale over xmas of just about everything we own to get this funded and finished asap now,

Got an AEM WMI kit lined up, toyosports massive FMIC core, going to replace all the FMIC pipes with 63 instead of the 51mm it's got, going for a gizzmo EBC to allow us to run variable boost too.

Only thing I'm stumped on: KO4 oil and coolant lines, anyone got any they fancy selling me?

There were some on PH/ED38 last week or the week before mate, might still be there.

EDIT: FKN Fred
 
Cheers boys, I've e-mailled the chap, so lets hope he's still got them!

Mini will NOT be for sale though :p
 
Starting straight after the new year Karl, I've got a week off at the start of Jan, so I plan to spend that ripping it all apart, cleaning and painting everything that's had 200k of use, then start putting it back together and seeing what I'll need to refab for the ko4.

Should get it back together and running by the end of Jan, then I'll talk to Bill about mapping :)
 
OK, so I think I might have been a bit hasty buying this small port inlet manifold, as I've just found these on USRT:

Have short injectors and the fuel rail doesn't reach down far enough? (e.g. Genesis 550cc in AEB/AGU or 16v). The Genesis "Unspacer" is your solution. These slip on top of short injectors and seal against the o-ring. The Unspacer itself has an o-ring on top that seals inside the fuel rail.

Unspacer [INJUNSPACER] - $10.00 : USRT, Usually Sideways Rally Team

at $40 per set + shipping it seems silly not to do this I think

Oh? And what made you change your mind?

The knowledge that I'd never hear the end of it from you if I slapped a small port inlet on my large port engine :p

Still, I'm glad you prompted me to search, those spacers are actually cheaper than the small port inlet I bought! i guess that'll get cleaned up, painted to make it look special, and stuck back on ebay!
 
$70 shipped via express international mail, problem solved for £44. Wish I hadn't spent £35 on the small port inlet now!
 
Money my dear man, and the knowledge that it could be sorted with a small port inlet if nothing else came up.

Also, I was under the impression at the time that AUM seats could be screwed into the AGU inlet, and I've only just found out this wasn't possible after Tufty did some testing for me.

Knowledge on ~550cc AGU/AEB injectors seems pretty limited to be honest. and Bill has proved on Steves setup that 440cc injectors arn't up to it.

At the time, the genesis 550's were retailing at £400 for a set! and we paid a lot less than that :)
 
I think standard AGU injectors are 206 or 231cc, I've read varying reports.

They're ****** tiny though!
 
i'm guessing no need to upgrade them unless going BT set up ?

will they be fine for the K03S/stage 2 set up
 
standard injectors are OK for 99% of ko3S stage 2 setups yes mate.

You get some odd mappers who claim they can't do it, and some freaky cars like jardo's that run too much boost and max out the injectors leading to all kinda of trouble, but generally they're absolutely fine.

Typically you need 380's for a ko4 setup, and 550s for a ko4 hybrid from what I've gathered.
 
Thanks Kev, handy page that one. I don't know much about the brake specific consumption aspect of it, but it confirms my thoughts that I need 550cc injectors for what I want, ultimately when the engine has forged rods we will be aiming for 320bhp or so, so there is some headroom in them still.

Welly tried the astra VXR injectors which are claimed to be 470cc, but tehy maxed out straight away.
 
BSFC of 0.5 is fine. I dont think modern engines end up at 0.6 or higher as that page suggests.

I think the ratings for those VXR injectors might be out, or they're rated at a different fuel pressure.

If they really were 470cc, then they're ~23% larger than the standard S3 injectors.

Given the standard S3 injectors can manage ~270hp, the VXR's should have managed 330ish. I dont know what welly managed to get out of them, but his final figure was around 330hp and he needed bigger injectors to get those figures.
 
Yup, welly did indeed need bigger injectors for his final figure of 338bhp, and it's those very injectors which I now own.

So far, nobody with a hybrid has come even close to matching Wellys results, but as of yet, noboby has built the exact same setup, something has been different every time, manifold, head port size, compression ratio, FMIC size, etc etc.....

Mine will be pretty much identical in every way (same turbo, manifold, downpipe, FMIC, full AGU engine with higher CR and large port) so hopefully I stand the best chance of replicating his success!

VR6 MAF housing paid for this morning, so hardware wise, all that's left is the TIP from Bill and a downpipe before I can bolt it all up and get it running on actuator pressure to see if it's going to work!

Will probably fit the VR6 MAF housing, and temporarily throw on a 4 bar FPR with stock injectors just to get it running and idling so I can put a few miles on it.

obviously I wouldn't dream of running it full throttle even on actuator, but if previous setups are anything to go by, it should make a max of 230bhp on actuator pressure, and the AGU injectors can provide fuel for 230bhp with a 3 bar FPR, so with the 4 bar in to gain some headroom it should be fine. Still wouldn't risk full throttle though, just want to put miles on it to test it out before mapping, to hopefully avoid all the problems Bill has had with previous cars that arrive with him untested and end up requiring loads of corrective work!
 
Woow I didn't think you would start on any of the hybrid parts until the new year.looking good prawn

Jardo where are those sold linky please!
