Simo's Turbo re-build Progress (GMC pics & video - page 18...) - Page 11 - Saxperience

I think the standard bumpers could look good if they are extended to meet the arches but they need to be fully colour coded imo....and i would remove the fogs and mesh behind them.

Kind of missing working on the car already!

But it is giving me free time to get some other stuff done, like clearing out some of my spare parts, which are now up for sale. If anyone is looking for turbo conversion components, take a look http://www.saxperience.com/forum/sho...d.php?t=311204

I'm planning to go and visit GMC shortly to confirm the spec of the work and I may well spend a little time tarting up the engine bay, once the engine has been removed

GMC appear to be making good progress.

I think I'm going to treck oop North on Friday this week to do some extra prep work on the engine bay, now the lump is out

Turbo has been sent away for diagnosis - should find out what the problem was in the next day or two. Lets hope its not something too expensive

The jobs list has now been agreed, but I dare say a few extras will creep in during the build (isn't it always the case?) The only thing that is certain, is that I'm not going to like the bill one bit!

For those who are interested, condensed list...

- repair turbo oil leak
- supply & install 4 x larger fuel injectors
- supply & install turbo-spec cam shafts
- supply & install 6-paddle clutch/cover/release bearing
- supply & install MA shaft spline kit
- supply & install Quaife ATB
- remove & inspect gearbox. Advise to use or replace. Source as required.
- supply & install race spec valves & port head to suit
- supply & install modified manifold and turbo studs
- supply & install forged pistons to suit bores. Advise re rods
- supply & install modified water circulation through turbo
- supply & install appropriate oil restrictor (banjo) to turbo inlet
- supply & install alloy header tank
- supply & install genuine driveshafts as required
- remove ABS block, wiring and all sensors.
- supply & install twin master cylinder with bias adjustment and appropriate piping
- supply & install wideband LC-1 and display - link with ECU
- map Predator ECU on rolling road - actuator pressure set at 1bar
- customer to advise setup of AVC-R to modify boost pressure up towards 1.5bar for mapping. (if transmission can handle it!)

Bits to remove & keep to one side

- AP twin plate lug drive clutch & cover
- Weber Alpha AFR meter
- Unlocked ECU

always the case that random bits creep up! and sounds like it is going to be a fair bill

rather you than me! haha

and what has been done so far other than the turbo? any news on if the gearbox is good or not?

Quite a lot has happened so far... John certainly isn't hanging around!

The brakes are off ready for modded hardware/pipes, engine is out and will be in pieces by now ready for cams/valves/headwork. I guess John will soon be measuring up for pistons. There's a suspicion that the turbo casing is cracked, so will be interesting to see if thats the case.

The car went up with either a knackered clutch or gearbox, so that will need to be looked at to determine whether box is at fault or not... if it is, another will be needed before fitting the Quaife.

Im still not 100% sure on what gearbox to fit. Close ratio for acceleration isnt necessarily what I need with the turbo having oodles of spare grunt. A more civilised ratio may help the transmission to last a little longer?

CAn say nothing but good about johns work. I took my 106 on bodies up to him for sorting an mapping an his work is top notch an if there is any updates or probs he rings you straight away.

An he sticks to his tight time scale which he sets unlike some!!

Your in safe hands simo

Andy_K · 12th May 2010, 13:45

Will be watching Johns progress on your's Simo, as its 99% probable that my car will be going up there for final tweaks/mapping at some point. Hope they sort it all out for you

Alanapone^p · 12th May 2010, 13:47

MY GOD!!! that's a lot of work... and a lot of cash! lol

Hope it all goes well, really looking forward to seeing the car all done

Well said.

I've used John for the last 5 years or so. I rate his workmanship, respect his knowledge and enjoy having a few beers with him too

Sophia_Bush · 12th May 2010, 15:55

fair play Si thats a fair amamount of work but at least you know it will get done no worries.

adzvtr · 12th May 2010, 18:17

lots of work here si, will be worth every penny tho when its all finished,
keeping my eye on the progress as wen mine is ready will be looking at going to johns for finishing myself.
cant wait to see this car running again, it is the original after all. keep it up m8

i have been thinking the same thing but im unsure what you thinking of fitting? a more civilised like the vtr box or something a little different

Simo^p · 13th May 2010, 00:38

Ive always used VTS or 1.1 boxes, but have been considering fitting a VTR box for longer gears, better top end and less load through the revs?

I'm taking a risk sticking with the MA after the trouble I've had in the past, but am spending too much on the rest of the engine to warrant changing the MA at the moment, lol.

that sounds like a plan! and yea not worth it to play around changing boxes if you get a vtr one and it explodes within no time what is it on at the mo a 1.1?
