Yeah i have the JDM spec Type-R and i was wondering about boosting it. Anyone out there that has a boosted Type-R please give me some input. I wanted to boost it on non stock internals of-course like 8.5/9.2 CP pistons, stock Intake mani., Turbo exhaust mani., larger oil pan etc etc etc. The only thing is i want this to be a daily driver i would only be running it at about 5-7 PSI for normal everyday. So could i have it as a daily driver? what else should i do to prep the engine? and just any other input that you guys could give me would be great. Thanks

 

if you are goin to stay at 5-7 psi, why change the internals. my good friend has a drag kit on his 01 type r and had stock internals for over a year with the fmu. if you arent going with boost over that why change the internals?

 

a friend of mine had a stock Type R boosted on stock internals and made 400whp on a daily driver

Why so low of a compression???

One would only hope

Thats a big requirement for any boosted setup..


I would say that you have alot of learning to do about turbo setups before trying to build one yourself..

I think the compression is fine....but the rest of your statements I agree with.

8.5:1 is too low for anything, 9.2:1 is still kinda low but acceptable.. I perfer 9.5:1-10:1 for boosted applications..

 

why a 10:1, to still give you the low end torque? i know the buicks i am used to were 8.5:1 but they have 2 more cylinders. i was always told on honda's 9:1 is good. there has to be a reason 10:1 is better. my question is, is it for low end? like coming off of a red light? my 1.6 has no *** anyway, it is very high strung so i know that is the trade off.

 

i boosted my 01 r at 6psi had it running at six psi just for like 2-3 weeks went to the track on 195/50/15 toyo tires...full interior ran a 13.3....my car was making 261whp at that time....

losts of fun with boost

Sure, you do get more lowend/off boost power but also you don't need as much boost to make the same power.. Tuning is more important with higher boost but in my opinion its worth the benefit to go with higher compression..

The motors that I build I shoot for 9.5:1 compression for boost..

thats on a 4 cylinder correct?
again goin back to the buicks with 8.5:1 they dont need the off boost power. OR would a buick benefit from a 9.5:1 engine? now you got me thinking as i am looking to build another 3.8L. he hee.

Yep.. This is on a 4 cylinder.. I think any motor would benefit from a little higher compression with boost..

 

sweet thanks for the info. you now have me thinking. take care man.

 

I agree with Tgraves, I am running 9.8:1 CP pistons and have no problems and I have plenty of power with lower boost some people just like to say that they are pushin 20+ psi but not really makin power because they are only running 8.5:1 or so

Im running 10:1 compression on my B16 and I just finished breaking the engine in so ill let you all know how it works out with boost next week..

 

sweet man keep us posted.

 

9.8:1 making 10psi and runs just fine.<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by boostedcivicsir &raquo;</TD></TR><TR><TD CLASS="quote">

Talk About Thread Hijacking.</TD></TR></TABLE>A big reason for this is the design of the heads, pistons, cam(s) and the fuel injection system. You can run 9.5:1 on a GN but be ready for detonation. Unless you have a nice set of aluminum heads. Either that or you better be running stock boost with some good *** gas.

 

&lt;-- ran 10:1 comp in a H-series for a while..... blew it, but comp wasnt the issue, i was ......

PS: the rebuild has 9.8:1

 

Thanks for all of the help. Also i was shooting for 5-7 PSI only for when im driving and then just up the boost when neccesary. So would stock internals work with that? Just to be safe i wont use stock internals . What would be the most (NOT meaning DD) PSI i could run on the 8.1 CP, 9.1CP, and 10.1 CP pistons. Thanks in advance

 

5-7 psi is completly fine on stock internals. I would said say the $$$ u use for internals on tunning.

this is the things i am after....
i had no problem running torco 118 nitrous blend in my car before but it was stock compression with 28 psi. thanks for any info on the buicks.

 

I just had my JRSC'd R tuned on 10 psi w/ stock internals & made 258 whp & 173 whl tq. Not a turbo set up but hope this will help U make a decision on compression.

Who cares what psi your running, its what power is the motor putting out that matters.. With 8:1 compression you can run more boost than on 10:1 but still be at the same power level..

 

i think that b18c's have turbos stock.

Uhhh.. You know, I think your right.. Arent all type-r's boosted..

Put on your flame suit noob..

WOW, you wasted your first post on a response like that..
