Turbo upgrade

Ok so I am geting my car ready to do a turbo in it sometime this summer.

I have a 95 civic Ex coupe w/D16Z6 engine.

so far i have done the folowing upgrades on the engine
________________________________________________
AEM fuel rail,Fuel presure regulator, and Fuel filter.

AEN Short Ram air intake

AEM cam gear.

AEM power pully kit.

MSD Sport Compact Ignition system.

SS Header
________________________________________________
Things I know i need to get.
3" cat back exaust system.
some kind of engine management system.

The turbo i will get will come in a kit with BOV and intercooler.

1st Question:
Am I going to have any problems with geting a 3" exaust for the time before i get the turbo?

2nd Question:
What turbo would you recomend for this setup?

3rd Question:
What turbo exaust system would you recomend?

Any other bit of advice you would give someone going turbo for the first time?

gee, just about everything u bought already was a complete waste of money. the fuel rail, regulator, and filter will serve almost no purpose for a bolt on kit with no internal mods and stock injectors.

the header is obviously of no use once the kit goes in.

as for ignition, the MSD is pretty much useless without a blaster coil.

the short ram may or may not be compatible with the turbo.

cam gear on an SOHC motor is wasted money... especially on turbo since u cant dial out the intake and exhaust valve overlap.


as for exhaust, your best bet is Thermal. they make a 3" setup. also, no use going 3" on the exhaust since your catalytic converter is only 2" diameter. think about a higher flow cat.

as for the turbo size, go with a Garrett T3, with a .50 A/R trim compressor, and a .48 A/R trim exhaust with a standard turbine. this will allow the motor to produce boost at a lower rpm and still have enough flow on the turbine side to support 7000rpm on a 1.6 litre motor.

full boost without a boost control setup should hit around 2500-3000rpm, compared to a T3/T4 hybrid (.60 A/R trim compressor, .63 A/R trim exhaust) which hits full boost at 4500 rpm. in other words, T3/T4 is complete overkill for a 1.6 litre motor.

Fuel system a waste???:confused:
I though that if you installed a turbo the stock fuel system is not good enough to suply what is needed with the turbo. wouldnt i need a better fuel system so that I reduce the chances of detination from running lean?
doesnt my engine run 1:1 on the fuel system? 1lb of presure for 1lb of boost? maybe im way off but i dont see how upgrading the fuel delivery system would be a waste.

As for the MSD i do have a blaster2 coil.

short ram should work fine for the turbo, why wouldnt it? as long as its the right diamiter and not too long it should work.

I am planing on doing a racing cat with the 3" otherwise what good would it be to get it?

Thanks for the info on the turbo. I am guessing i would have to go with a custom built turbo to get what you are saying, is that right?

upgrading the fuel system isnt a waste.....you just upgraded the wrong parts. the stock fuel rail is capable of handling more then you'll ever squeeze from that engine without totally rebuilding it into an unreliable full race car. as for the fuel pressure regulator... your gonna need a hell of a lot more then a 1:1 rate most people i know are running 10:1 - 12:1 depending on application. god i wish it was 1:1!! seeing that spike into the 100psi+ off the gauge mark is not a very comforting sight (speaking as a passenger and not even the owner!! i could imagine thier fear)

besides most kits come with all the stuff you need anyway like the new pump and regulator and some with injectors. if you wanna get something to upgrade the fuel system get a stand alone or at least a piggyback for some fuel correction.

the short ram might work if you can cut it and jam it down in there.

as for the exhaust, just buy some earplugs, a gas mask and a police scanner and run an open downpipe :flipa:

the regulator u got is not the right one. as for the rail, it's prolly too big to run the fuel pressures you need on stock injectors. make sure u have the old one handy if u run into problems.

for boost fuel, you'll need a high flow fuel pump, usually comes with the kit... and an FMU, which comes with most kits. depending on the brand, it'll either be additional injectors or a Vortech/Cartech FMU.

like the other guy said, you'll need much more than a 1:1 boost fuel ratio to support it on stock injectors. more like 12:1.

As for the short ram, the turbo system usually comes with a pipe and filter, also. the short ram may be made to fit, but it may not be configured to fit. it depends on the bends in the pipe and how it can be situated.

what you SHOULD have upgraded is your injectors only, since u bought a kit. the kits usually come with everything else. or, to really have done something well, u should have spent money on strengthened internals to run more boost. Fuel rail=$120 Fuel regulator=$100 (AEM), $50 (B&M) Fuel filter=$80 (AEM) SS DC Header=$350 AEM Short Ram=$100.

approximately $800 on wasted parts... if you did some shoppin around, you coulda got a set of connecting rods and pistons and possibly a cylinder brace to beef up the bottom end for more boost. you'd had to have done the installs, but it would have been a much better way to spend your money.

or you could have gotten a turbo cam and a new clutch, which you'll definitely need.

or a Quaife ATB differential to make both wheels lock up when launching, plus divert torque tot he outer wheel to improve cornering performance. the Quaife would have been a damn good part to buy.

you want engine management? buy my haltech

I guess I need to explain that I am not looking to make my car into a 12 second car. This is my daily driver and I just want to add a little umph, but I want to do it right.

So defiantly no on the down pipe only

Why would the AEM fuel pressure reg an incorrect one? as long as i can adjust it i should be ok, right? or why not? I want to understand this so I can get the right parts and do it right.

As for the 1:1 fuel ratio I was just meaning that is stock. I didn’t expect to be able to run boost that way, but knowing it would require more fuel under boost is why I decided to go with the upgrades in the first place. I also read somewhere that my stock FI would be ok for a lot more power then I was going to put out. but from what I read here it sounds like that is not possible.
It sounds like I can’t keep the fuel stuff I have but just need to put in new injectors.

Sorry if I sound stupid I just want to do this right the first time.

the AEM fuel pressure regulator is NOT a boost dependant regulator.


you really need to just wad up enough cash, and drop your car off at a tuner to let them just do the work as they see fit and learn as they do it in front of you
