wishing your family all the best sir!

Remco

thanks mate

john.. bit of a sore point so stop poking it..kicking a man when hes down an all that.. i'll bide my time for the ideal oppertunity to have my turn..i shouldn't have to wait long i'm sure

if i ever do another one i will just list everything i can possibly think i might need on top of all the parts and labour , then double the whole estimate and i am likely to be about somewhere near

Rob is Barbz running the same spec as yours?

no mate different piston , rods, manifold, turbo and of course mine has an external gate...having said that he has another one of these turbos and a manifold same as mine but i believe they may be for sale..as he is happy with the 400+ he has for now as its just a runaround..when he has time and inclination he may go full power but with him not competing or tracking as yet its pointless him going any further for now plus he has too much of other peoples to sort out ....thats my understanding of the situation..the manifold would be a good buy for someone as we got discount for buying a couple so it would work out cheaper than trying to buy one direct..

Cylinder head 1


I guess they are NOT too shabby

WOW you got to love Barbz's work!!

Bloody hell what size these valves are....

i've got a feeling they are the 2.4 stilo head sizes as per my head, however the valves are custom made ( i'm guessing, mine were anyway ).

Oddly enuf you loose torque, but can flow tons more, thus the limit to power here is your turbo setup, hence why he's fitted a monster turbo with a ported shroud...

one I'm looking at closely ( once he does the guinea pig bit ! )

I'm sure it'll be fine

more the reason to keep your aux belts in good nick !

did you get the pics of the clutch mate?

valves are custom made and head is a well doctored stilo should flow well thats why i had to go with that manifold as well try and let everything flow to its maximum capabilities ..same with the external gate..i have tried to remove all potential restrictions from internal gate to standard manifold (not that it was particularly restrictive but it would have reached its limits before the new one)..

good luck friend

Good luck with it - I would be interested in hearing more about the turbo, 100 bhp gain and faster spool than a GT3076 is a big claim...

Has the manifold been flow tested at all?

I hope the Mrs. gets better soon.

With such a turbo it is time to install a block guard... else you could kill your block at high loads!
Interesting project - good luck with that.
Juergen

thanks for good will toward my wife its nice so many people have wished her well

with everything that went onto or into the car i drove barbz mad with my internet scouring and asking him to read this and that and give his opinion..even he thinks the turbo is a real find though yet unproven on the coop.. but there is a fair bit of info on evo and subaru strokers using it and theres a few direct comparisons with data sheets available everyone made over 50bhp more plus big torque gains and all spooled and responded quicker everything we could find on the turbo was really positive and as i say it made just over 100bhp difference on one of them..i have said already i expect around 600bhp from this set up providing it can be mapped cleanly and we can deal with any little niggles that (usually)arise
i know i have stuck my neck out and would have been wiser keeping shtum but i genuinely expect it judging by what the other 2.4 have made and the improvements across the board and the information on the turbo...

as for the manifold the makers assured me it will be good for 600 but we would be finding its limits if pushing toward 700..they have had a 20vt engine though in a marea or some such do 612 with it (or so they tell me) ..

i hadn't planned on a block guard but will look into it

if it all runs right i am going to nos it higher up the revs and in the higher gears but i have so much to do including strengthening/building a stronger box as it will be the weak point ..the clutch has been rated to 550lbsft i said 530 in one post but its 550.. but the way they test them cold with a big force (its been explained to me how they rate it) its definately able to cope with 600lbsft and thats all at once cold so it will not be the weak point i think the box will go first

Any idea how 'drivable' the clutch will be?

we need more photos!!!

Let's just say you don't want to get stuck in traffic with it

as begbie says it wont be as good as the standard article but what they have done, as it was explained it would be a daily driver, is make all the concessions they could to make it driveable..the one john s used i believe from barbz was a little heavey the surface area is much bigger which will mean less force should be needed on the pedal..they have also fitted leaf springs to keep it under constant tension..they also built it with drivability as one of the factors i specifically required of it as i say they knew it was a daily so although it will be more on off and certainly sharper and slightly heavier i am hoping it wont be as bad as some paddles as mentioned they are not nice in heavy traffic ..but it remains to be seen how good/bad it will be for normal driving..all will be revealed in the next week or so and i will be giving a full rundown of my first drive in it for those interested

I have some experience with precision turbos, on an evo 3 belonging to a mate of mine. It's a touch on the smaller side than the one you pictured, fitted to a 2.3 lump. I was sceptical at first because I'd never heard of them, but wow ! it's a cracking unit. You had better get to work on that gearbox because it comes on hard, thats all I'm saying.

Clutch, in fact, looking at it, very similar to the one I almost picked, however I went for a single plate helix ceremetallic jobbie, lighter than standard...not as grippy as this one, however time will tell, certainly looks the business.

think you should REALLY look into a gearbox cooler & some very GOOD OIL & some spare boxes !


clutch 2

clutch 1


enjoy

tricky... thats why we had them do this clutch mate when they can do a single plate rated to 450lbsft as i think most including that would struggle with what we found the turbo was giving on other strokers but like you say its the gearbox i expect to be the weakest link and i am looking into my options on that

This all sounds amazing.
Cant wait to hear the exact figures of power and torque after mapping, and see the car as a whole.

You gonna be getting down some meets and Santa pod, I wanna see and hear this thing go!

Good luck once again.

I would be interested in your opinions on the clutch. from experience a lot of companies definitions of easy road use is very different from mine!

The reason that I asked about flow testing the manifold was that if you of the branches is restrictive then you'll get heat build up in one of the cylinders - not good on an engine / turbo of your spec.

your welcome to try the clutch for yourself whenever we can arrange to be in the same space but i will post my thoughts on it next week
i am trusting the guys that made the manifold as to thier claims it flows well and is ok for over 600 there are cars running them in other countries though admittedly not many as they are so bloody expensive but they do a lot for the vw/audi brigade with similar bends on and they are highly thought of..i wish i had the facilities to flow test or knew someone that did but its all built up now so we will run it up and see what happens

cheers technics i will be taking it to the pod or probably one of the other tracks as the pod seems to be a little too busy for my liking..i cant wait to see what it can do!

It looks like the tig art - I think you made a good choice.
Inner diameter is 36mm, isn't it?! This definitely will be enough for your wanted 600HP, I think.
This year I will try to get 650HP out of my new GTX3582R with a smaller manifold (34mm, only). We will see, if I am successful.
To your other points:
1. A block guard is a MUST for this performance. Else you will get a cracked inliner. Please have a look to Brazil - they all got cracked inliners with more than 600HP.
Please have a look here:

2. I have a dual clutch installed as well - I decided to use a organic disc and a sintered disc. This helps in traffic, because it slips a little bit more.
3. I decided to use minor torque and more rev. This helps the gear box to survive. Therefore my specialist ex F1-tuner Hartmut Lohman changed my oil channels of the hydraulic lifters to get it more resistant against high revs... we copied this from Ferraris with hydraulic lifters...
4. Moreover you should use the old integrale-style 5-gear box.
For this gear box three streghtening plates are available.
In addition you can buy a streghtened gear set with other modul of the gears, but same gear ratio.
I installed all these parts to get a durable gear box... but only on the street we will see, if it will do the HP.

Juergen

thanks juergen..i am using the early 5 speed and we know about the strengthening plates.. i am running it in and using it at first with standard early 5 speed but am taking it easy whilst barbz strengthens a box for me.. where do you get the stronger gears?..i may change the ratios slightly as a slightly longer 1st and 2nd i think may help me get the power down better....i know shortening it would give me bigger traction issues..anyway i thought the issues with the cracked cylinders were due to cylinder pressures from high boost..i am not going to run more than 1.8 bar probably less so thought i wouild be ok..as you can see from the pics of the head the valves are as big as we could go without even more expense so i had hoped that would help with less torque though if i had someone that could do the oil channels i would have gone for that as it is we will raise the limiter slightly to maybe 7250 but will see how it looks on dyno before making the descision

again with the manifold i went with it as the 36ml should again help with top end flow and lessening the torque which was always going to be what caused me all the problems with the way the turbo delivers so i have done all i can without having a mate thats a formula 1 tuner!(lucky man)to make it as drivable as possible but it will all come down to how well it can be set up on the dyno

i have just checked that thread and they were using 32psi which is over 2.2bar? anyway its a lot more cylinder pressure than i am going to run and 1.8 would be my lot i don't think i will need more to make what i want.... one thing about barbz work it makes good power without having to throw a lot of boost at it..i didn't want to go down that road with it being a road car i want it to have some longevity and high boost and longevity dont seem to go well together (just my opinion before i get examples of high boost set ups that lasted a million miles)

Rob

You will need a block guard at 1.8bar, most you can conceivably run without is probably 1.6bar so as Juergen says it is a must for your desired goals.

Looks very nice, well done for sticking with it and pushing the boundary's, I think that the best bit about the build

Screamer pipe FTW!

What is a block guard? Is it costly?
