My lambda had done just shy of 140,000, so was well overdue for replacement.

Bit of a git to replace, due to the water pipe being in the way, but some judicial levering of the pipe with a metal bar had it sorted.

I'll wait untill i replace my manifold to do that job, heard it is a mare though.

Its dead easy to do, though to be fair when i did my aircon compressor i cut the mounting plate part off the pipe to allow it some movement so it made things like the turbo replacements and such like easier and it doesnt even rattle like you would think, just stays in place and has nothing to really rub against as its metal to metal

Good news on the engine though nigel, your turbo sounds very much like mine in the spool up stakes but i havent ventured past 1 bar boost yet im waiting for the LPG mapping for that to come into play, ill kindly be asking them to max the LPG injectors out and then pull it back as necessary to start off with to avoid anymore issues lol

Good to hear nigel. I dunno about your claims about the spool up but i'm sure we'll see when you get it mapped.

why

I tried it again on the way home tonight. Its giving 1/3 bar at 2,000rpm and 0.8 bar at 3,000. Two gauges can't both be lying, and I'm certainly not. I reckon when I up the boost, it'll be giving 1 bar or more by 3,000.

Nigel, are the boost figures given while you were on full throttle or just partial? Before my car stalled tonight it was around 0.3 bar just below 3000RPM, but the boost controller was off, turning it on makes it much faster. This was with partial throttle though, and if i recall from driving with std turbo and controller off, its not much far behind actually

im not saying your lying nigel. All im saying is that i doubt it will be much faster with a higher end boost. The engine will still make boost the same speed but just go to a higher figure. However yogisdk is right. Partial or full throttle will make a difference.

Ross

It was at full throttle.

the reason that I think it'll go higher than 0.8 bar at 3,000 is that 0.8 bar is all I'm seeing at 4,000 as well, suggesting that this is the base setting of the actuator. This would be about right, as the actuator on the GT28R was set at 0.8 bar, but only gave me 0.65 bar base boost. The GT2871 actuator is set at 1 bar, but seems to be giving 0.8 bar at the gauges

It'll all be academic in a few days anyway

Yeh as i said we will find out!!!! But all the best. Im planning on comming down to TOTB to check it all out!!!

Ross

Its getting near Nigel!!!

time to turn the boost up!! and get that remap!!!, hope the weathers not too hot tomorrow

Joe

I've had my oil and filter change, so I turned the boost up to 1.2 bar today.

OH MY GOD!!!!!!

The car is demented. Its waaaay faster at 1.2 bar than it ever was before at 1.35bar. It absolutely flies round the rev counter.

And the noise - it growls from 4,000 to about 5,500, then it just howls. Its completely addictive.

It feels like the 7,000rpm limiter is going to be too low - the way it attacks the upper rev reaches is truly mad.

Spoolup is increased to about 3,200 when boost starts to rise. At 3,500 its boosting pretty hard, and by 4,000 the world is in reverse.

I'm Sooooooooo pleased - can't wait for the mapping session to see what its going to be like with some serious boost.

However, there was a bit of a mild panic beforehand.

On the way home from work on Thursday, I hit a serious size boulder. It was unavoidable, I simply had to choose which section of the car I wanted it to damage. I tried to get it through the section of the car with the greatest ground clearance, which I did, but even then, it wasn't enough.

It sounded like the bottom of the car was being ripped off!

It hit my lower subframe brace first. It now has a substantial dent in it, and was quite well bent.

Next was the subframe itself. A small scuff and very minor dent. It touched the brake pipes on the way through, but only managed to take off the underseal.

Next in line was a bend in the exhaust centre section - a dent about the area of a credit card, but about an inch deep - thus greatly restricting the cross-section area of the pipe. Finally, it managed three small dents in the backbox.

Iceberg straightened the brace with some brute force, but its going to have to be replaced eventually. He also saved the centre pipe by drilling a hole, levering the dent out with a pry bar, then welding the hole up again.

I suppose it could have been a lot worse. Wheels are untouched, brakes and bodywork are fine.

Anyway, I'll post up the results from the remap as soon as I can

Sounds like its gonna fly Nigel.

Few years ago I managed to go over an exhaust that had fallen off someones car. Unfortunately i didn't have time or space to try and get it through the centre and it went under both nearside wheels - sure I got some air! No major damage but a slow puncture.

Anyway I digress. What sort of boost are you planning on running when its fully mapped? and when is the remap?

Chris

Sounds like a lucky escape there Nigel, have you broken a mirror recently or something??

Your coop sounds like a monster once again, get some videos for us.

I'm sure a few people will have cameras at TOTB next week - I hope so, as I'd love to hear the car from the outside. I sounds gorgeous from the inside, so it should be even better from a fly-by.

Planning on running at least 1.5 bar, maybe as much as 1.7 - 1.8, depending on how well it fuels on the rollers. I have a set of 5 16VT injectors ready to go in, so the only limiting factor should be chargetemps.

Temps will be fairly high tomorrow, so I certainly won't see the maximum possible power - we'll have to wait until a rolling road shootout in winter for that.

Excellent.

1.7 - 1.8 bar, thats insane. I can only imagine what that would feel like. So, the big question, is it laggy?

Did you sell your chargecooler in the end then?

Nope - not really laggy - its about 200 - 400 rpm later than my GT28R, but I can still get nearly a bar of boost at 3,000rpm, so I'm more than happy

Nobby - yes, chargecooler sold when I fitted the FMIC, as the two can't be fitted together

The spool-up sounds goood.

I was planning on coming over, but I've just done 36 hrs on 3 hrs sleep and about to start another night shift , so think I will be fit for nothing in the morning..doh!

By the sounds of it and driving Fleas car I think your spool up will be similar to a GT28rs.

Joe

Disater narrowly averted! I'm still at PTS as I write this on my PDA - car hasn't turned a wheel on the rollers yet.

About 10 miles short of Luton, I started to notice some oil smoke when I floored it. I backed off, with visions of a dead turbo or a knackered piston.

An hours diggng around by the guys at PTS discovered a split oil feed pipe to the turbo, which was spraying straight onto the downpipe and manifold. They've worked really hard and managed to change a Cossie oil feed pipe to fit.

They're now welding a wideband sensor boss into the downpipe - should be on the rollers in an hour or so.

More later.....

It sounds rubbish - have you considered getting an RX7 instead ?

Is it being mapped for the full 100 bar today ?

Good Luck Nigel.

I reckon you'll hit 355-65 bhp at 1.5bar at approx 6300rpm and 325-35lb/ft at 5400rpm.

Jules.

FCCUK'in 'ell

SPILL

Ross

still mapping, but how about 319 bhp at 1 bar

ooof. ur gonna run 1.5? hmmm..... thats gonna be a biggy!!!

Ross

So 319 * 1.8 = 574.2 bhp. Fantastic

Jayell..... if only.......

Ross

Is that not how it works then ?

Fraid not... its all down to luck!!
