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

look just ring AVO and they can tell you on the spot seeing as our answers aint good enuf. grrrrr

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....

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?

**string** · 21-09-2005 01:02 PM

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.

I'd like to know why quangsa said this
