    Glad your happy with your results Steve, they are very good although the torque figure does seem low.

    Surely if that torque figure is more accurate, shouldnt that mean you shouldnt need any upgraded internals such as rods. I know its "more safe than sorry" but standard rods should be able to withstand a increase in about 50ft-lbs.

    even on 113k engine?
    rods is peace of mind for sure. fit and forget

    log block 122 and see what torque the ecu thinks is going on...

    I agree (if) the torque being seen on my dyno is how it is and not some measurement issue, then the rods *should* be safe, however, anything thinking that one of these hybrids will just bolt onto a stage 2 car will see >2bar boost spike, at which point they will more than like get intimate with their engines internals rapidly.

    The hybrid took some calming down in the initial spool within the map to prevent this spike. (mbc fitted now anyhows, which achieves same thing.. n75 alone will nuke the rods I think left alone without map to suit)

    So are you saying if you fit a CR hybrid turbo you may be better getting a MBC & mapping to suit instead of the N75 Bill ?
    I only ask as I was speaking to Mark the other day & we were wondering wether just bolting on to a stage 2 car would work....
    Also when are we talking about changing valves, over 350bhp ?

    I dont think there is any way that bolting the CR turbo onto a stage 2 car will work as bill was saying at start the turbo wanted to go to 30psi. Injectors i would say are the best bet so then your not stressing the fuel pump! If you look at it as close to IHI power without as much expense (no manifold) unless of course yours is cracked

    Those manifolds are worth replacing if possible, with a better item when more become slightly more readily available at a reasonable price. The OE item of us have which most of us have is simply ****!

    MBC would clamp the inherant spike it would otherwise have.
    It might suffice initially on a stage 2 car, but injectors wont be up to it, and fuel scaling will need to be adjusted. I dont know how much of this adjustment can be achieved by unisettings fuel adjusts, but 4bar +pump or larger injectors will be needed judging by what I logged on steves s3 this weekend.

    high revs/heat/power is where I would be looking for valves. hybrid is the limit of what I would feel comfortable doing without valves. All depends on how lucky you feel. I have run IHI myself on bog stock ibiza engine for many 1000's miles without valve issues. revving to 7800rpm. maybe i was lucky?

    dunno.

    did you keep my revlimit at 7800 bill or did you lower it again i forgot to ask?

    Hello Speedy Steve, good to see you are happy with the results, I have been waiting to see the results of the hybrid (as I am sure alot of people have).

    Now that you have been the guinea pig and won I think I will go down the same route.

    Can I ask where you got the 440 injectors from, and/or the part numbers as there seems to be quite a few varients. or does anyone know of any 'scrap yard cars' that have similar sized ones as standard?

    Thanks again for starting a good post, and you will have to keep us updated

    brand new for less than £140 for a set of 4

    Badger with the everything speedy steve's done to the engine what would you suggest the next engine mods would be?

    Exhaust manifold?
    Inlet manifold with R32 T/B?
    Large port head?

    Thanks for the info. I was thinking about adding a hybrid turbo, injectors and uprated fuel pump to a stage 2 setup up then get it mapped to suit.

    Be good to see how a hybrid K04 and GT28rs compare as dont they give similar power outputs but different delivery, similar cost to ini.

    WMI next
    exhaust manifold as and when one comes onto the market and is proven to be reliable


    I dont see a largeport being needed as such on these airflows or larger tbody

    Would be good to see a power graph or even better drive it lol. 300+bhp / 250lbs is an interesting figure. Wonder how it feels compared to my (roughly) 250bhp / 290lbs.

    I had to Google WMI! No idea what it was! So what difference will water meth injection make?

    lets hope he comes see me in it then :beerchug:
    think the misses will end up hating him though as it be more cash injected into the car oppsss..

    i currently have; fmic, 3 inch downpipe and cat, tip, 4bar, bmc, stage2 mapping
    so if i was to go for the hybrid all id need is the rods and turbo correct???? also how much would you charge to mapp it and would you trace any faults etc in that price such as boost leaks, i dont mean spend hours fixing stuff, cheers

    As Bill has said before its prob better to go 440 injectors and 3bar to save the fuel pump from having to over work itself. So id be tempted to do that aswell Kev

    It would be good to know how well this flows with the supported mods and extra mods like ex manifold and a large port head/manifold,do you think it could reach the 350hp mark with these?

    i dont think going to a large port head with valves and spring a 75mm TB and inlet manifold a new exhaust manifold (when one comes out that works) are really worth it to get the little extra power if you want 350+ go BT to do it with a K04 youll just be pushing it to much and it wont last! the only things i plan to do to mine are exhaust manifold when a good one comes out and WMI as the EGT's get rather high as it is
