GSR vs. ITR

Hey guys

talking to a guy that owns a Civic with a Type-R and he heard from some guy that only works on ITRs that the problem with the ITR is that they are a "blueprint" engine, says to upgrade them messes everything up. Like putting a cam in requires upgraded valve springs and so on (any internals require major $$$). Also says that GSR and the rest of the B18's are upgradeable piece by piece.

Anyone know anything about this??

Mike

performance

sounds like your friend read a bad thread on Honda Tech and is giving you some sour information...or is trying to keep you from buying an ITR engine

when you put anything on an engine it "throws" things off...its called tuning

I think all honda motors are sensitive to internal upgrades. One has to choose the parts very very carefully.

It took plenty of engineering to perfect it...


Just my two cent

If I were to put a cam into an engine. I would at least go with a Stage 2 for the extra little $$. It's not that hard to replace valve springs, etc.

Also your friend that only works on ITR might have too much of an EGO for the all mightly B18C5. :P

anything you do on a car affect everything else too. even a set of wheels 'throws' things off.

the ITR is a superior engine. if you can afford it, then go for it.

if you want a motor that makes more hp and trq then a type-r or gsr pm me and the cost is under a type-r swap.

Awesome guys, the guy that only works on the ITR is not my friend, don't even know the guy (by what you guys are saying, maybe I don't want to know him). A guy at a stand at DKN7 said he could sell a B18C5 for 4500 with everything needed, is there any cheaper prices to get one, or is it less expensive to get a GS-R and work with it.

Seems like everyone had a GS-R for a swap at Darknights, plus the Integra Type-R with that 9700 RPM redline just seems like it would be a lot of fun.

Sorry guys if I seem like a newbie to this

ITR at 9700 rpm??? I think not. You would get some serious valve float and would be looking at a blown engine with 0 compression. Highest stock Honda redline is 9000 rpm on the S2000.

I think many people fail to inderstand the forces at work when something is spinning at even 6000 rpm.

Just think to yourself.

by the time you say "eleven", the crank has turned SIX THOUSAND TIMES!!!!!!!!! you try counting to six thousand it'll prolly take you the better part of an hour and a half.

peak power for the B16B is 8200 rpm. I doubt redline is far behind. the B16B is the highest revving B-series

though it was 8400 for B18C5 and its power maxes out at something like 7800.

rpM or rpS? i think its 600 times not 6000.

i would take a gsr over a type r just ecause of the combustion chamber design and i know that i would be hopping it up so that is an important thing for me.

Consider that the JDM ITR engines are hand ported and polished as well as torqued using a micrometer. OF COURSE mods will affect it.
