I'm considering, in about a year, buying an inlinepro turbo kit. I have a MY01 with 50k miles. Only mod will be HKS Hi-Power cat back exhaust (comes in this thursday). What i'm wondering is what do I need to do in the mean time to prepare for the kit? I had a 98 S/C civic and it really wasn't done correctly (not by me) so I want to be ultra careful this time. I plan on getting the inlinepro kit with all the extras (HG, EMS, injectors, etc). I currently have a stock clutch and 50k miles on the diff. When I get the kit I plan on installing it myself as I feel i'm technically inclined enough to do so. After the install I plan to go straight to a tuner. Now, since i'm spending phat cash on the kit, I want at least 20psi. What I need to know is what things should I do in preparation for this? As in diff, cluch, axles, driveshaft? Also, if I order the HG first and run it before the turbo goes on, what differences will I notice with the lower compression?

 

I think you sould re evaluate your goals. Rather than just saying I WANT 20PSI. FIRST and formost a bone stock F20c isnt going to handle 20psi. Second sure some have run 20 psi with just a hg but i doubt that it will be reliable in the long run. But then again while talking reliablily i was only running 6psi when my #1 cyl top piston ring failed and scored my cyl so you cant ever tell when something is going to go wrong.

Running NA with a 3mm hg is not somthing that most people do, but i believe it can be done harmlessly(the only down side being a loss of hp). Most get it done while putting the kit on or get it put on after. Running that much boost with just a hg IMO is a bad idea. But its your engine. Like i said some get away with it and some dont.

If you are stuck with 20psi on the brain then 20psi SHOULD put you close if not over 500whp. Your stock clutch WILL NOT handle that kind of power. Most will barely handle 350hp. Then there is the rear end to consider. Some have kept the stock rear diff w/high hp and never had a problem. While others (like me) have blown diff after diff while still NA.

Im not really an expert on some of these matters so someone chime in if im wrong.

 

This is exactly the input I am looking for. I say I want 20psi, but you're right, I have no clue what I want yet. Me going turbo is so far in the future (about a year) nothing is certain yet.

What should I look for in possibly building/making the diff stronger. I've seen some ppl talk about a silvia rear end. I'm assuming this is no "bolt on" deal, what's involved and what other options do I have?

Also what should I look for in a new clutch. This car will be my daily driver. I've driven an s2k with a stage 2 clutch and actually like it.

 

If I were you I wouldn't do anything.

A lot of things can change in a year.

 

to be honest.. 20psi is pretty high on a stock block...you will have to upgarde alot of parts for that.. like fuel pump, you will need a new exhaust 3' and tons of other things. if I was you.. i would stick to the 13-15psi.. you can get great gains from that

 

At 13-15psi I assume i'll still need at least a stage 2 clutch? And what about the diff?



It'll probably be less than a year, I work at a tax software company and tax season = overtime = phat cash so that's probably when i'll do it.

 

Tsk Tsk Tsk. Come on you guys, don't feed him information that is false.

My engine: stock + headgasket

My tune: 19.5 psi in February. It's about 18 now that its much warmer out.

Issues: Zero

It's all in the tune. And please, people need to stop relating HP to boost pressure. They are only partially related.


Robodeath, your best bet is to pick a HP target. Work backwards from there and figure out what you want in terms of power delivery, sound (exhaust), turbo application (drag, street, autocross), money, and that will help you to determine which turbo, kit, and options are a best fit for you.

When you say you want 20psi, that isn't really very descriptive. 20 psi on my setup is VERY VERY different than 20 psi on a Lovefab GT1 setup. A difference of maybe 100 HP.

 

i understand what u are saying.. but just because you did not have any issues with 20psi doesnt mean every other person wanting to run 20psi on stock block well have the same luck.. all i am trying to say is.. 20psi on a stock block can be done if done right.. but if not tuned and with out the right parts .. it will be one walking time bomb...

 

5psi without correct tuning is a time bomb.

Tuning ≠ Luck

 

its all about tuning and having someone that knows the S
