turbo b18c7 vs b18c,

if you was to turbo the type r engine. including the internals would i be the same as turboing a vtir b18c? power wise. you would get the same thing right because everything is changed? or would the b18c7 be stronger as its type r

id say it would be similar but the type r would go better as it has a much better intake manifold and it has a different head.

if u gonna do internals dont waste the extra money gettin the R becuz u gonna change everything insides anywayz.

yeah i know thats where im stuck man. but still you got type r interior and shit! haha

interior? i thought ur talkin about the engine? :confused:

as for the intake mani. you can change it to a skunk2 manifold

well if ya got the cash then get the ITR cos its got the better brakes and strengthened and lightened body that u need

are we talkin about the entire car or just the engine.

ive been told by a few tuners here in WA that if flowing a cyl head or porting it wont make much difference if your going to go FI as opposed as staying NA.
i was gona get my cyl head flowed and get a edelbrock manifold but it make f all difference once i boost, this is looking at the cost of flowing and manifold wich is well over 2gs including all labour as opposed to getting and fitting at turbo kit which i can get for under 4500 and fitting is only bout 1000.
i think that is way better bang for buck than ripping you engine open and shaving off 1 gram off Aluminium

But is it wrong to say that the more power you have NA, then the more power you'd have under FI?

Given the price difference between the vti-r and type R (around say 8K or so, you could buy a vti-r and boost it for the price of getting a type R. So price IS a big factor i'd say.

yeah but if your after power wouldnt you rather spend 6 7 gs go FI, rather than spend 4 5 gs on porting and polishing, flowing intake mani, cams, header,
when you just bolt a turbo kit with everything you need and get 100hp+ and the torque to go with it that comes on at round 2 to 3K rpm
as oppesed to NA 50hp+ that you wont feel till you hit 7000rpm and id emagine torque aint that great ona smaller displacement b motor until your in vtec.
well thats the way i look at it,

I just re-read the first post and it doesn't seem to be a thread about NA vs turbo.

Its about whether to boost a vti-r or type r engine.

oops sorry well id say buy the cheaper motor so you have more left over for mods

lets bring up the question of......

B18C7 Vs B18C using only stock internals.???

b18c7

speak to toda au on the forums. he was one of the first in aust to boost the type r back when he workd for hypertune

F.I ype R all da way....im doing mine now and its real nice to think there aint too many typr R turbos out there! + spend 4.5k on a gsi and get 160kw-180kw or spend 4.5k on a type R and get 190+ Kw.

Great.......stupid replies with no reasoning behind them.

So can anyone confirm that the more power you have NA, the more power you'll have FI if you tune correctly?

Also, if you turbo a vti-r teg and a type R with the exact same setup and boost.........would the Type R make more power and how much more?

type R cost 5 times more then a gsi.

so you'd rather pay 5 times more for the R to get that extra 10kws

a rule of thumb to remember wyn. if you start with more then youll always be ahead of a motor that has less. so if you had to put the same turbo on a vtir and the type r youll be ahead again

thanks for all your help guys, yes 2mprss ill run you, probably loose but.
ive done research and found the following. vtir and type r block and heard are 99% same. just different internals. if you change the internals to a turbo setup. eg all the headwork changed to turbo, pistons, rods. the type r wont be type r. TYPE R IS only high rev. thats what makes it type r. so the vtir and type r engine would be pretty much the same as you change everything anyways including the cams.

well keeping to the question of retaining ur stock internals....

ive always heard that the vtir will react better to mods as oppose to the type r....with this mentality, the vtir in stock form if turboed shuold give more gains then the type r

reason the type r has been tweaked and tuned heaps to squeeze everything out of it to produce a high revving engine....to turbo it will loss its high revving capablities which means all the R&D that went into it to produce a high revving engine will go down the drain...ie (the rods, cams etc have been designed for high revving N/A purposes)
the vtir is also a high revving engine but the piston rods etc are different and are not as highly tweaked and tuned to squeeze everything out of the engine therefore may respond better to the turbo....

keep in mind if u FI either car with stock internals the internals of a type r are alot stronger and therefore maybe more reliable but then again the compression could stuff you up...

i guess there are many factors to it and each with ther pros and cons, and thats leaving the money factors out of it...

after saying all this i could be totally wrong as i havent tried FI to any car let alone either of these.... :D

hope it helps in some way...

p.s. just talk to an experienced mech

Why can't you rev a type r once its boosted?

You can, boosting will not change a thing in terms of rpm.

Honda vtec engines rev high from a good rod stroke ratio and balanced rotating assemblies, not a limitation of power.
