hey i was talkin to my friend how i'd like to have a type-r in my crx. and i told him how i would like to build it and maybe turbo it. well my friend said that i'd be better off getting a gsr motor and turboing that cuz a type r has too much compression or too high of a compression ratio or something like that. i don't know much about honda motors so someone please tell me which engine would be the best bet to go with if you have big plans on making an insanely fast motor and money is not an option.

 

i've read that several times on this forum. most people recomend boosting an LS engine. it will be ALOT cheaper and from what i read on here, it will be much more boost friendly.

 

gsr. edit: ls might be better for your needs.

 

yea its a common topic, if you get an LS motor then you can boost higher than a GSR motor because GSR have higher compression and LS have lower compression. boosting a b18c5 is not reeally recommended

 

ok you people need to learn about turbos. and the creator, you should try searching cause there is 1000000000 threads on this already.

However you can boost anything.. I have seen 600 wheel horsepower Type R's and GSR's. You always can put lower compression pistons in the b18c's. An LS is great to turbo though as well.

Its all in how much money you got. However the c5 is a great all motor engine and if you want boost just get GSR or LS.

 

yeah so back to his topic.. type R motor vs gsr motor for turboing.. gsr .

yeah and like these guys said.. LS is good too

 

hmm ok so if for turboing a gsr beats a type-r then what about ls vs gsr?

LS engine would be cheaper, more plentiful, lower compression, no VTEC to complicate matters (arguably), tranny has taller gears (arguably better when boosting)..

 

people people people. its not the motor you boost. its the tuning.

you can boost a 13:1 compression motor and blow an LS's doors off. you just need to know what you are doing.

get a tiburon, and start with that dammit.

or learn from a huffy 5 spd.

yeah yeah yeah.. we know.

but which engine would you be least pissed about grenading? which is more common? which is more turbo-friendly (or least non-turbo-friendly)?

this guy is obviously just starting out. keep that in mind.

 

i say if you don't have mucho denero then go LS.. i saw stock LS boosted with an SC34 last nite, spank the ***** off a brand new STI.. i was laughing soo hard b/c a 30 thousand dollar car just got destroyed buy a FWD 10k car... plus the LS tranny has a more friendly feel while shifting, becuase of the long gears.. your not in and out of them like a ITR/B16 trans.. the LS head sucks, but the motor has a longer crank stroke, and shorter rods for more tourqe but less hp, but will rev 1000rpms sooner then the gsr..

a gsr is nice and has a more agressive/balanced geared tranny then the ls, but its a more expensive motor and hard to come buy after its blown up.. gsr also has higher compression shorter crank stroke, with longer rods, which will make less tourqe, but rev higer for more hp.. also the gsr head out of the box is good till about 500whp..

for the money boosting an ITR motor isnt worth it unless your gonna build it because of the out of the box cost, but its pretty similar to gsr except it has even higher compression, and a fast shifting geared trans.. ITR also has awesome cams for turbo as well and the head is good till 500whp + like the gsr brother..

hope this helps a little bit..

 

lol do some searching first, you need to figure out what you want to deal with as far as power/reliability/ work to the engine to boost, etc

engine work for turbos is expensive

i agree wit him

 

if money is a concern i would go ls if not go with a gsr engin and sleev that bad boy and lower the comp i like vtec and boost! iam currently runign high 400 on street tuning with my built type R engin and it screams wen it it vtec great power band... me like

ps..i was half awaked wen i wrote this lol ....

oh yes and b18c5 are not too cost effective too boost cuz they dont last long mine lasted me about 2 months then i had to rebuild it they are not boost friendly and are picky engine even with good tuning(aem)

 

If you don't know the Type R motor has higher compression and what that means, you shouldn't be putting a turbo on a N/A engine at all. IMO

I'd start with a VTEC block simply for the oil squirters. Since money is not an issue, send the block out to be sleeved and increase the displacement through boring it out. Of course the head will be sent out to be ported. Study compressor flow charts carefully, and pick the best turbo for your needs. Piece together the turbo kit.

Of course, if money was not an option, I wouldn't start with a CRX, but that's neither here nor there.
