I'm lookin to turbocharge my GSR. I got a 2000 w/ 40k miles on it. This guy from some chatroom i was in said that its not a good idea to put a turbo on a GSR. He said the "engine couldn't handle it" What is he talkin' about??? Or is he right?

 

Think he meant the compression level of the GSR. You can turbo a GSR but if your going turbo people recommend you go with LS Turbo. The difference is GSR motors are 10:0 and LS are 9:2 I think. GSR can handle turbo its just that you have to know about high compression with turbo or so. I don't even know a lot about it but my friend told me it.

 

oh. ok, i'm kinda following you on that. thanks

 

GSRs have 12:1 compression. running turbo on it is fine, you just have to be careful with the amount of boost you run.

edit: heh, my bad... 10:1 cr in gsr

You can boost a gsr motor but if you wanna go with anything more than like 8 lbs you will need low compression pistons and it would be a good idea to sleeve your block.

 

Kyo Kusanagi is correct. GSR c/r is 10:1. the general rule of thumb is that too high of comnpression + too much boost= detonation problems.

As far as turboing a GSR itself, it is kind of silly, given the high factory compression, small displacement (compared to LS or B20), and the poor flowing GSR head.

There's nothing wrong with turbocharging a GSR, its just that it is not the ideal car to turbo, that's all.

ok. then what about supercharging. or is this not such a good idea for the same reasons of turbocharging?

</TD></TR></TABLE> higher compression= more power. low *** 8:1 compression and such is just a bandaid for crappy tuning. The gsr is plenty ideal to turbocharge if done correctly.

 

Jesus christ.

We will be actively monitoring these threads for ridiculous information like:

"GSRs have 12:1 compression"

10:1 like they said above. And yes, boost is a terrific idea. Do yourself a favor and do a search in the Integra forum and the FI forum. "Boost GSR" "turbo GSR" "JRSC" etc...you can learn a lot that way, as well as pick up on any ridiculous statements people have made, and continue to make, that others have already discounted in previous threads.

haha....in our dreams they come w/ 12:1 stock. try 10:1, buddy.

 

Boosting a GS-R is awesome, but make sure that it's something you really want before doing it. It'll cost you a few G's minimum.

I had mine boosted for over 30k miles without one single problem. Stock internals and DragIII kit at ~7psi. The trick to having a problem free car is to install it carefully and leave it alone (besides normal maintenance).

 

If tuned properly GSR's are awesome for bOOsting and due to the high compression u get more power from the boost u run.

 

The GSR's compression will provide you with better spooling. 10:1 and correct fuel delivery and fuel management will provide a safe situation to boost. boost an LS and a GSR with the same setup / timing / boost and the GSR will yield you the better WHP. ask the FI forum....but search and research first......

those poor folks in cali would have to throw in octane booster everytime they filled up.

I was under the impression that GSR had a better flowing head than LS.

Don't forget the GSR tranny owns the LS one.

LMAO Thats funny as **** when its so stupid the mods get involved.

 

I actually have a turbocharged GS-R. It is absolutely possible, and I personally think it's great. One reccomendation that i have though, is not to run more than 8 PSI. A/F management is a must! When I first got my turbo in at 8 PSI, I was still getting detonation problems, though, that stopped when i put my front mount on. My speculation is that the FMIC cooled the charge temp. E-mail/PM me if you need some help boostin the teggy!

 

You made a comment about Supercharging your gsr. i think that's a GREAT idea. This is just my OPINION, but here's how i view the integra engines. LS=turbo, GSR=supercharge, ITR=All Motor. The jackson racing supercharger is perfect for the gsr engine, it responds so well and they just work great. plus its more sleeperish w/o that intercooler, and the cool sound of the 'whine' is sweet.

 

actually the pro-charger kit is so much better then the jrsc. it is such a sweet setup, and the power is incredible from that kit.

 

Boost and compression are directly related, if most guys have not figured it out yet than they should just quit typing and read more ****.

 

One of my buddy have a Turbo GSR, It pulls very hard. I test drive it and I didn't like the tranny. Shift every 1-2 second. But he swap it out for an LS tranny.
