Hi im interested in stickin some throttle bodies, well bike carbs on my mk2 vtr. The engine is about to be rebuilt, and then hav added mods such as cams and head work. I having it all carried out not by a garage but sumone who rebuilds engine and stuff so overall shouldnt be too expensive.
Any ideas how difficult it would be to fit during an engine rebuild?
Wats needed? Wanting to keep spending as low but not too low so its goin to break all the time!
Found bike carbs on ebay for lik £55?
any other ideas or suggestions

you think adding some bodged inlet will gain you 30 bhp alone? lol

mines runnin 161 and i had a vtr previous. jus waited till i could get a vts rather than wastin money on a vtr. but its jus my opinion dude. i dont no how these tuned vtr' s survive a day on 8v. no wonder i dont c any at track days.

yeh i no dude. i wud think of waitin but my vtr needs its engine rebuilt, well i want it rebuilt. but was thinkin of puttin tb's on at the same time. most ppl go for the vts, but i using wat i hav. wantin to be different.
and 2000 nah i dont think a bodge one will jst giv it that. with the rite management and everythin, its easily possible

a well setup vtr is just as reliable as a vts to the same spec


to run bodies (dependant on type) you may need custom inlet manifolds an maybe standalone management as the sensors may be different ect

it can either be reasonably simple to drop on and plug in the sensors (if allready on standalone)
or it can be a rigt pain

good on you mate be different would think 125/130 would be achivable i am sure sophia bush said people have got 130 from a 1.4 bottom end with a 1.3 rally head so sure that power could be gained from a 1.6 to

Cheers for that mate. yeh its good to do sumthin a lil different. I would hope to get that power from it.
Its an idea and was thinkin if i was ever goin to do it. while it was bein rebuilt wud be the rite time
and cheaper

if you do deciede to go down the 16v route with tb's 106owners are having a group buy on kms direct to head tb's www.106owners.co.uk/forums/showthread.php?t=58444, i think on some other website are doing the standalone mangerment on a group buy aswell.

If u cant afford the insurance on a vts how you guna be able to afford the insurance on a vtr will bodies?

carbs are a massive backwards step on fuel injection.

food for thought :P

cant you use the injector rail and just use the boddies to let air through.. sorry if its a nooby question?

you would need to drill holes in the carbs to run the injectors, with the injectors you are then really wanting standalone as trying to run a map sensor on bodies is nigh on impossible. Just carb tuning alone is very basic and in many cases often runs poor and needs tuning quite often.

Im not a fan of the wannabies with bike carbs tbh, imo if you want to do it, do it properly

fair play mate so more work than it is worth? wish i could afford some nice boddies and a s lump:(

people get them to work. But then again ive known of a few over the years to do it on the cheap then bin them off quite quickly...

as ryan said bike carbs are a step back in time.

have a look as some model bikes went from carbs to throttle bodies, they can work, but you need an inlet manifold from bogg bros or sandy brown??

the tbs then fit onto this via silicon tubing, you will need to sort out the linkages etc. some bike tbs use 2 injectors per a tb as well.
to run it you will need a standalone management and an uprated cam will give you a good setup with a set of tbs.

but it really isnt a straight forward job, but it can work. i have seen them on a 106 rallye and on a 106 gti.

stay away from bike carbs, some bike TBs can work. im not 100% on the models as some changed to electronic injection. could be the R1s after a certain year, think the gsxr and hayabusa did as well, but dont quote me on that.

What bodies do these look like? I have no idea so posting it in here as its on an 8v. Looks quite impressive when you look on the other videos from the user...

im guessin turbo is the easier way forward then, unless its proper throttle bodies. anyone no of a low milage vtr engine goin cheap???

turbo is no way the easier option. will cost you about twice the price for a decent setup. you could run a low boost setup, not sure what power you would achieve, maybe 140? depending on spec. but it wouldnt be as reliable as throttle bodies.

if you do it properley, you will need forged rods and piston, thats £1600 already, not to mention, turbo, manifold, ecu, mapping. the turbo route is much more expensive.

bike bodies are the cheapest route, about 200 for the bodies, send them to sandy brown to be machined, 450 i think. then you just need management and a cam to make it worth while.

but the management side can be done cheap, i have heard of people using piggy back ecus like dastek.
