And im i two minds on going for a locked transferbox, what power can you shove in to it?

You should be able to use the standard Air flow meter, just relocate it so it not being blown through. Put in on the intake side if the turbo cos they dont like being blown through with forced induction.

I put 350bhp through the standard f25

That dash looks wicked. I've always wanted to do a V6 turbo. just never had the money or time to do it. hope this turns out ok. can't wait to see it running.

**jamied** · 22-06-2005, 21:42

evening gang...setting myself up for a big weekend of work on the car since the weather looks to be ok again, most of the work shall be on the body but im also getting the rest of the engine ready, now heres a few questions..

at the moment i have a 2.5 and a 3 ltr v6 block and bits...reading a few messages on the board should keep my 2.5 ltr rods as they are stronger than the 3ltr ones ?, also can i use the 3 ltr crank or are they the same?..pistons should be on there way from Matheus428 soon (forged with a comp ratio of 8.5:1) i have the 3ltr heads which i need to start work on the porting and flow and also upgradeing the springs and guides and mostly all the pipework is done for the turbo...just need to locate some flanges for the exhuast and turbo. Nearly finished fitting the side skirts and also going to have a look at the rear suspention because its sitting a bit high and looks like a tractor..

were this one has less pipework meaning less heat loss and the pipes are all equal lenths.

is there any real rule on this or would the difference be non noticable.

...can't you put a smaller turbo on each three cilinders?

**jamied** · 23-06-2005, 11:11

Twin turbo 3ltr v6....hummm...would be nice..

..but i think the room at the rear of the engine bay is a bit restrictive and the heat produced by the rear turbo might cause a few problems.

**jamied** · 03-07-2005, 19:26

Evening Gang...another busy weekend spent on the car, was working on the brackets for the rear of the gearbox and trasfer box and some more of the electrics, also a bit of the bodywork ready for spraying in about 2 weeks time...

...got my cam covers from astrarally

mate...cleaned them up and gave them a coat of paint while the wether was nice and hot

Next week i shall be fitting the drive shaft from the trasfer box to the rear box and finishing the rest of the bodywork ready for the spray session also re-tubeing all of the brake system....phew..also the pistons should be here soon from Matheus...

**jamied** · 12-07-2005, 22:17

evening gang....off to Dorset tomorrow night for a long weekend and then i have all next week off from work to....spray the car....

..cleared the garage out and have picked up some kit to make a spray booth in the garage..so by this time next week the car should be very black and very shiny..

...then with any luck the engine shall be finished in about 5 weeks time ready to go in...slowly its getting there..still doing well on the price..3lt V6 turbo with NoS and 4 x 4 wheel drive..spent about 2k.

and a gazillion man hours

**jamied** · 12-07-2005, 22:28

lol...i only get weekends on it due to it being in the g/friend dads garage..so if you look at it..2 years = around 100 weekends..which is around 200 days...take off weekends away and rainy days..still works to about 150 (ish) days...not bad for something that started as an oil change..

**jamied** · 07-08-2005, 19:54

Started painting the car today with 2k high build primer..

in my makeshift spray booth...was going fine until the gun failed on me..

the setting neddle in the gun has threaded resulting in the primer spitting out of the gun and 'blobbing' over the place..also the primer started to dry quite quick for an mix of 1000ml primer and 300ml hardener...might need to get some 2k thinners along with a new gun tomorrow. as for the enigine, the pistons from Matheus should be flying there way here soon and i have sent the head gaskets off the cometic as a template for some copper ones...soon the monster will be alive...just got to finish off the primer next saturday, then spray on a few coats of black 2k on sunday..leave it a week then sand and polish... phew.

Danneth · 07-08-2005, 20:48

only just read all this think im more excited then you lol

**jamied** · 07-08-2005, 20:51

lol...mostly everything is done or halfway and once painted its all just sling everything back in so it should be 80% finished in 2-3 weeks...

i can't wait to find out what power i shall get from her..should be above the 300's i hope...

Danneth · 07-08-2005, 20:53

James82 · 08-08-2005, 11:32

I cant wait to see this thing around Northampton!

Ginge · 08-08-2005, 11:36

Sweet omg i cant wait....

dathers · 08-08-2005, 11:37

Been following this one for ages,looks like the end is now in sight!

Are the new pistons your using standard size and just hone the bores for new rings or are they oversize requring a rebore?
Either way,the run-in miles are gonna be a nightmare,just waiting to fully unleash the beast!
Just out of interest,Are your new pistons cast or forged,and what are the piston manufacturers recomended piston-bore clearance?

One of 3 things will happen:

1. It will get nicked
2. Jamie will crash it

3. It will get nicked

**jamied** · 08-08-2005, 12:02

the pistons are forged ones from Matheus on here with a comp ratio of 8.5:1 same size as 2ltr let ones and fit in the block like a glove (tried some LET ones for size first) as for running it in i think i might just sit on a rolling road overnight...

...as for security Dom..i still have my Tandy made car alarm..

and by the time anyone has nicked it they will need to stop at every petrol station to refuel the thirsty beast..so it will be a big possabilty that the crash would be top of the list.

Lol.

Can always keep it round my house, pretty safe here and we have a pretty mean dog, lick any potential thief to death!

Promise I wont take it out

dathers · 09-08-2005, 12:02

Just a tip regarging an alarm system,
I built a nova XE from a bare shell a while back,and before the dash-board went in i installed a TOAD Ai606 and rather than just cable tieing the alarm wiring ontop of the main loom i unraveled the loom,installed the alarm and then got a roll of the proper non-sticky loom tape to loom it all up again,so all the alarm wires are totally hidden,i also made all the connections 'in' the loom(soldered and heat-shrunk),most alarm installers make alot of the connections at the ignition switch/indicator stalks just because its easy to get to,its also 'dead' obvious which the alarm/immobiliser wires are to a thief.
Another thing so called Pro-installers do is just stuff the main control box up behind the dash,not properly screwed down,and not in the metal casing that 'needs' to be fitted for thatcham approval,If you do it yourself you can secure it properly,neatly and out of the way.
Then to get your thatcham approval you need to visit an alarm place to have the system checked and the certificate signed,which i needed for insurance.
I got a brand new TOAD Ai606 for £99 off E-bay,fitted it myself to a MUCH higher standard than so called Pro's,£20 for the certificate,so all in all i have a top quality alarm/immob for £119 that is over £300 fitted by a Pro.
Well worth it,get rid of the 'tandy' rubish!
Dave

**jamied** · 09-08-2005, 17:41

The Tandy is a joke with me a Dom, he use to work there with my brother..

(poor dom)..as for the alarm, i have seen the TOAD ones on ebay so i might get one now its been recomended.

ALSO...my pistons are on the way....

...Matheus p.m.'ed me to say that they are done.....cool.

pic of the pistons at the bottom of page 1...all 8 of them..(6 for use..2 for spare...lol)
