yeah, turbo's flow well with pretty shit mani's tbh lol, forced incuction ftw!, simo's is a fine example of whats esentially a pretty basic mani, which is flowing pretty high bhp figures, my mani issues are sorted now as i bought jason's kit.....

......well for now, i think once im all fitted up i may begin fitting up and making a 16v set up for when i get bored

cut the cat off at the collector and weld on the correct flange

the middle 2 pipes are almost perfect and the outer 2 just too wide, but a cut and reweld and there perfect

my old setup had a vtr cast manifold with a t25 flange welded on and that did 200 bhp easy, ive only gone to this type as i need an external because of the nos

thats a pretty good find tbh mate! how did you manage to stumble across that? should be easy as fook to get the other two in place!

your old set up ran 200bhp? was that on standalone of mf2? pressure? just trying to gauge what im gonna make on pred at 1bar.

im thinking of building a 16v on the side next year

, looking at those gt25/28 import things from america, see how long the last, for £160 if it lasts 6 months itll be a laugh,nice external w/g should go well (this is for the ax plans

)

you need to hurry up with this mate! i want to see a super powered 8v coke can rip some awesome 1/4 miles

the old setup was on a dastek running 18 psi on a T2/T25 hydrid

ive been looking at manifolds for years trying to find one that was close, i tried that one when i was doing a head gasket on one and its the closest ive seen, i do have a 4-2-1 i was going to bastardise but this is closer

my plan is to have it running for march and get it to the strip, show these 16v how its done

blackie_2k5 · 25th November 2010, 20:46

18psi from a t2/25 hybrid? thats quite high.... did the turbo last? im thinking of taking my t25 to turbo solutions in darlington and getting them go hybrid on mine.... depending on how much they'll charge(theres also a turbo technics t25 hybrid the same unit as mine on ebay not far from me, but hes after daft money), what power exactly did yours make mate? im going pred and was gonna try crack 16psi out of my unit the way it is, by my rekoning it should be capable of kissing 200bhp, but im not sure what its gonna make :/ ..... and that annoys me some what lol

as said, i cant wait to see this finished, 8v powa! ill stop spaming your thread now

as i planed on running the car at the pod in march i thought id better start with its rebuild

ive got the bottom end back from being balanced, it was blanced with the old clutch and flywheel and im glad i had it redone

this is the balance prior to drilling

and this is after

as you can see its near on perfect now so should have no problems reving to 8.5k, the guy who did the balancing said hes built loads of roller rocker 8v engines for raceing and he revs them to 8.2k so fingers crossed it will hold at them revs :?

honed the block and fitted the new ACL bearings with paste so i can fit the crank back in

also received the new rings from omega so got them fitted now just waiting for the woosner rods that should be here this week

also converted to block to run a jp4 crank case breather

then converted my AP release bearing to work in the BE box

on the down side the S1 inlet doesnt have anywhere to fit the nitrous jets very easily and after checking space it seems the turbo is a little bigger than i 1st thought so the pipes i have for the manifold wont work so back to the drawing board on that

some coin gone in2 that m8.looks the muts nuts !!

dannygti · 6th February 2011, 21:06

what are you planning to do for the manifold now?
rest looks good mate

tweeqd · 6th February 2011, 22:41

im not sure mate, i might just convert a standard vtr one for now untill i can spare the £1k for a custom primary designs one
the only problem i have converting a standard one is my turbo in non gated so i have to run an external wastegate

can you tig weld or know anyone who can?
if so have a look at my thread and the manifold i have made, maybe come up with something lik that?

tweeqd · 6th February 2011, 23:14

thats an awsome looking mani
i can tig weld and ive had an 8v flange and t3 flange laser cut out of black steel, i just cant find any pipes/bends to use for it anywhere
my other problem is its in an ax and i dont have the room you have in a 106, my turbo has to sit alot closer to the block
