i heard that a gsr with a type r head and internals would be the same as a type r engine. is this true?

 

It would if you got it P&P'd

 

he already has the head so there's no need

the only thing that's the same between the B18C1 and B18C5 is the bare block.

 

There are some more differences. I have been told that the heat treating process on the C5 block is different which makes it more rigid. The type R block's inner sleeves are thicker for continued higher cylinder pressures, oil pump gear is designed for more output, there is an oil cooler on the type r block also. the crank, rods, pistons and oil squirters are also different. they maintain the same engine control systems, same sensors, same water pump. if you want to make a GSR with the ITR internals, put some money into the oil cooler, buy a new oil pump and install it. you can run shot peened stock rods with the ITR pistons. I say get the JDM PR3s they make a bit more higher compression. change the rod bolts out to ARPs and also buy the stock HG and ARP head studs. With the ITR head, you will need the ITR manifold. If you stay GSR up top you will maintain good torque and just about 11+:1 CR. I have 1K on my new motor and it is loving its life so far. 800 miles of under 6K and I started getting on it tonight. I have 1K now and its time for its first oil change within the next 500 miles. Good luck with your project. I estimate my first dyno will be in the 165whp + 125-130tq
and 125 at 5250.

my frankenstien:

Unmodified P72 GSR head, ITR stock valvesprings, ITR LMAs, Skunk2 Ti retainers, GSR cams, VVIS manifold w/ported secondaries and portmatched to 68mm TB exit, ITR block: non-modified, stock intake with comptech filter and 4" wide by 3' long fresh air extention, stock header and ECU with a 98 ITR muffler.

 

GS-R's also have the oil cooler. It's water cooled and fed directly into the main water pipe on the back of the block.

Also, in order to use ARP rod bolts, you have to resize the big end of the rod to prevent out-of-roundness. It doesn't happen all the time, but it does happen, so you don't wanna be one of the many that succumbs to this.

 

GSRs do not have the oil cooler. maybe they switched from oil cooler from OBD1 to OBD2, but i know mine didnt have one.

 

gsrs do not have the oil cooler. I dont think it would be smart to argue that seeming as how I just changed to the ITR block, this past weekend I was staring this sucker in the face. GSRs are not so equipped from the factory, we welded/made a copper t fitting to feed the cooler from the GSR water pipe to the cooler and the heater core. working guud.

 

Actually, the '94-'95 GS-Rs had an oil cooler. For some reason the '96-'01 GS-Rs did not have an oil cooler.

94 GSR for SURE have oil cooler "sandwiched" between the block & the oil filter.

a type r head comes p&p from the factory

 

ok. I will check this... my dad drives a 95 GSR the damn thing is rock solid with 146K on it and very quick. I wouldnt be a bit suprised if it did... but doubtful.

 

Misread the post
Heres the other changes: http://www.team-integra.net/sections...p?ArticleID=35

 

hey hey...go eat monkey nuts! lamanamnoomy!

 

hes right on that one, checked my pops Teg and he definately has
one on his 95. DAMN! At least mine has one now
