yea i want to know if a drag3 turbo kit for a 99-00 si ,will it fit for a 2000 type r

 

yes

 

do they use the same downpipes? or do they make a separate one for the Si?
becuase the b16a will be shorter if its made correctly.

 

yep.

 

This may be a stupid question, but does that also mean that the greddy kit for an SI or even the GSR will also work for an ITR, since they don't have a kit for one, or is that a bad idea due to the different engines.

 

i think the downpipes will be the same if not really close.
as for the greddy kit , the one for the Si shoudl work but not the GSR, GSR's are *** backwards

 

Ever tried to fit a b16a header on a b18?

 

No.

The drag kit's downpipe is pretty much just a down and out... no flanges, nothing. Made to be custom fitted to any exhaust, etc. No flexpipe, no cat, etc is included. The greddy kit is made to boltup to the specific car's exhaust.

 

Is boosting the R a stupid idea.. and if you do a low enough psi... will the car still be reliable as it would be if it were n/a??? I know its a hard question to answer.

 

stupid? sure but damn its a lot of fun
reliable, might be......depends on the tuning

 

I have a b16 jdm heaqder on my r.....its shorter i think....i didnt really measure it

 

i bought my JDm 4/1 off a buy that had it on a b16 in an Si , so i know they fit, it might be a little off DP widse, but itf its a good dea grab it .

Boosting Rs is a stupid idea, stick NA , youll like it better

 

I'm wondering if Steve meant a b16 header on a b18c1 (gsr) head?
