    Could you guys upload a dyno chart? I'd love to see that. Also what are you guys using to tune it with? maf or map based?

    Sorry for the double post forgot we had this thread Doh!

    Thought an update would be needed on these cars as they have moved on a bit since the first builds, the Black and white one has now gone to Ireland to be driven by Shane O'Sulliven for the 2011 Prodrift series.


    Shane Lych's still has the VH45DETT engine from last year and is getting an overhall for the 2011 season

    Before work started and how it finished the season

    So is the dash as we have put a tighter fitting roll cage into the car, thanks to Peter at Fabricage as the last cage was slightly off the A pillar and Shane was banging his head

    As you can see the cage is much tighter to the A pillar and roof

    Now just all needs painting

    Engine bay after one season

    Now all painted

    Engine had all been checked and was perfect, considering its a standard NA running 260BHP from stock and we was running just short of 600BHP though it all it held up quite well, just gave the engine a refresh and a coat of paint.

    More heatshielding as been fitted as this thing gets so hot under the hood. Also new style screamer pipes ;)

    Just bolting it all back together now and hopefully will be ready to test next week

    looking good man. whats with those looped lines on the passenger side of the dash? surley you'd tuck them and put the front face of the glowbox back to make it look 100x cleaner?

    They're the brake/clutch reservoir lines - assuming the glove box is left out for easy access to wiring/fues ;)

    When you guys changed the tubs on the car did you loose any angle?

    Also how much angle over stock did you gain by doing the tub style the way you did? (to allow for the turbo's to fit)

    Hi Pual
    ok now I'm lost really lost
    I've been been around nissan's since days of high school

    I have a R33 and currently sitting in the bay is a VH45 with a S14 crossmember and the mazworx mounts and adapter plate. now im looking at how you guys mounted the alternator and ps pump, and was thinking 'how the F@#% dose that work'. as the swaybar/anti roll bar is 20-30mm closer towards the crossmember in the S14/S15 compared the R33.

    but when i look at all your photos the swaybar is not there, So where is it and how did you move it?

    I think the Sway bar is gone for good.... A lot of people in the US also do not run Sway bars when doing this swap, if the car is used for drift. as a Daily I'm not sure I would recommend it. Another option some people do in the S14 (since that is the cross member you are using and therefore the engine location is the similar) is cut a culvert in the oil pan to allow for clearance of the sway bar. but doing this be sure to add larger cans on the side of the oil pan so that you don't loose any capacity. I hope this helps.

    nah i don't have that problem with the sump, as the sway bar is positioned more forward in the R33 compared to the S14/S15 (due to the RB being longer). just make it hard to put an alternator there with the sway bar there as well, i might be able to drop the sway bar down a bit to get it to work tho.

    I can't really understand why'd you'd wanna get rid of the sway bar altogether?
