I was wonder what would be the best turbo to use? i have heard i can use a DSM one or a Saab one. Any others.?? Also what intercoolers could i use? I want to use a FMIC. Can i use the Izuzu NPR or a Saab one? once again afre there any others? Does anybody have the site for the junkyard turbos?

 

The NPR intercooler comes in two flavors, large and small. I intend to use the small NPR IC on my next RX-7, it is a practical size for a stock and upgraded stock Turbo II turbos and can support the power levels I need it for. It may be somewhat big for some DSM turbos or some of the other 'little' turbos, and it may or may not fit the 5G body. The large NPR intercooler is HUGE, avoid those, you will get serious pressure drop if you can even fit it.

That Saab Viggen one looks nice, but I don't know any details. $175 new from the dealer just sounds sweet to me.

If you feel like it, you could probably squeeze in an RX-7 TII intercooler as a front mount. Welding two together and front mounting them is a common RX-7 trick, but I have no idea if that would be OK in a 5G Civic body.http://www.homemadeturbo.com

 

get a old skool starion fmic. its big, front mount and cheap from junkyards.

 

Ive read that the T3/T4 or T25 are pretty good turbos to use with hondas. Also, if you can find an IHI turbo, that would be choice. As for intercoolers, the best custom fab ones ive seen are the Starion FMIC. Pretty big, can have the end tanks re located and welded on the sides for easy charge pipe line up and looks very :thumbup: sittin behind the front bumper. Just my .02

 

I don't know, I've heard some really nasty things about the Starion front mount.

 

Really? like what?

 

I'll see if I can dig something up.

In short, all the guys over on RX7club think they're trash.

Edit: Ok, after a little searching most just complain that they are too small with too large of a pressure drop. This may not be an issue with 14B's and T25's, but if you look to upgrade, there may be better choices.

 

could i use BMW E30 E28 E34 intercooler?

 

that IC looks ugly... but well i guess if ur going budget turbo then it'd be arite.

i dont know much about turbos or anything but i saw this custom IC on ebay. it LOOKS real nice, but i wouldn't know much about performance n stuff.

damn i wish i had enough money to even THINK about turbo

 

You're going to need a manifold so you can cut the flanges off to fab one of your own. All the non-Turbonetics turbo's I'm going to mention have the same flange, so it doesn't matter which car is the donor. You'll need a BOV, and the 1g DSM bov is an outstanding performer, and a dirt-cheap part. Don't buy a Greddy, you don't need it. I have a 1g BOV easily holding back 20 PSI on my 2g DSM. It sounds great, works great, and was $25. Get the DSM injectors off the same car that the turbo came from, and you'll be able to convert your fuel system with the right sized injectors for the fuel you'll need to deliver. Get a Walbro in-tank fuel pump.

The Starion FMIC is junk. It literally doesn't out-perform the 2g DSM side-mount IC... which is 1/4 the size. It looks great, but all the guys on the DSM boards that install it wind up complaining about it because it doesn't flow all that well, and it still heat-soaks. It's not worth cutting your car up for this IC. Also stay away from 1g DSM intercoolers.

Supra SMIC's work beautifully on DSMs because they flow enough for 500hp setups, and the pressure drop is really reasonable. They're much less prone to heat soaking than the 2g, and the inlet and outlet pipes are larger.

A Garrett T2small (T-25) would be a good turbo for a Honda. It flows about 405cfm with a 6cm exhaust housing... just like the 14b does, but it spools slightly faster. 95-99 cars that came with a T-25 are set at 11 PSI from the factory. A 2.0L engine spools that thing at 2100RPMs up to full boost, and the quicker that comes on, the better. This turbo is efficient to no greater than 14PSI.

The 14b has a lot of room for porting the exhaust housing and internal wastegate ports, and you CAN achieve 500cfm from it, but I think it would be laggy on a 1.6L SOHC Honda. The 14b that comes on the manual 90-94 cars is really good for top end, but it's more efficient in the 11-15 PSI range, and you don't need to push stock Honda internals anywhere near that hard. It may not be as efficient at lower pressures than the T-25 is, but people are running as much as 18PSI on it. It flows better at higher pressures than the T25 does.

I'd think a Mitsubishi 13c from a 90-94 automatic Talon/Eclipse/Laser, or a Dodge Colt turbo hatchback would be a better turbo if you want really fast spool-up, and low cost. It flows 360cfm which is more than enough for a SOHC Honda head, and there's lots of room for porting on it as well, unlike the T-25. The Colt has a 1.6L 4g61 engine and it greatly out-flows a 1.6L Honda, but that fact doesn't really matter. They're both 1.6L's, and RPM for RPM, their volumetric efficiency is a closer match for that turbo. The smaller exhaust housing will spin that thing up so fast you could be seeing full boost by 2400rpms. If that's where you start making power, you could be long gone before the guy next to you spools his plunderous T3/T4.

I have 2 16g's sitting around that I'd let go cheap. One's pretty heavily ported. The other isn't and only has about 5000 miles on it. They flow 505cfm unported and are efficient to 18-20 PSI, but once you exceed your turbo's efficiency, it's pointless to go higher. This turbo is most efficient around 16PSI. What's really pointless is putting THIS turbo on a 1.6L Honda.

I think T3/T4's are too big for Hondas. Some people have them working great on their setups, but when I see the horsepower numbers, they don't impress me. That T3/T4 is good for 450hp on a DSM, and I've never seen a Honda do that with a T3/T4. I've read about it, but with as many people as there are using it, I'd expect to have seen it by now. Nada. Lagmaster. Dual-Bearing cartridge or not... The wheel is too heavy.

Here's a picture comparison of a T25 next to a small 16g. The small 16g uses the same compressor and exhaust housing as a 14b, they just have different compressor wheels. A 14b's compressor blades are evenly spaced, and a 16g's comressor wheel is like the one in the picture. That's about the only way to tell the difference between the two.

Try message boards like DSMTrader.com and thepartstrader.com and you'll be able to find the parts you need inexpensively, without stepping foot in a junkyard. Good luck.
