View Full Version : EVO vs DSM

I'm going to try and compile a list of similarities and differences regarding the two models. This is going to be aside from the obvious superficial differences. Feel free to ask questions or provide further insight :thumb

Here's what I have so far:

*The MAS contains one giant honeycomb, so no (partial) removal would be easy.

*The MAS does retain the large calibration screw that can be backed out flush after digging out the blob of silicone. Refer to RRE (http://www.roadraceengineering.com/eclipsetech/2gmasadjustment.htm)'s site

*The boost control solenoid does not have the small restrictor in it that is typically removed anyways.

*The clutch slave cylinder has the restrictor and spring in place that is easily removed to allow quicker (dis)engagement.

*The reservoir for the clutch and brake fluids are combined into one, but are still divided within the reservoir itself.

*Gearing is much different. First redlines at 37, second at 56, third at 78, fourth at 108 and fifth is around 155. It appears to be geared well for runs up to about 100-110, beyond that, acceleration tapers. I'm well into fourth by the end of the quarter, barely hitting 100MPH trap speeds.

*The radiator cap is 1.1 bar. A nice, direct-fit upgrade for your stock 0.9 bar on the DSM.

*The stock BOV/CBV is a direct 2G replacement and (despite being plastic) will not leak at 12 PSI. I haven't tested it myself, but others are claiming it'll hold up into the low 20's.

*The vacuum line going to the BCS has two in-line metal restrictors similar to the plastic one found in a 2G (1G?).

*There is an external air cooler for the engine oil--been absent since the 90 model year.

*Magnetic drain plug for the transmission.

*The front diff and viscous coupling are located in the transfer case rather than the transmission itself.

*Two coil packs reside under the spark plug cover. Each fires directly to one plug (2 and 4) and has one wire to another (1 and 3).

This is just what I've run across recently. I plan on looking more in depth in the near future. New items will be listed in yellow.

Jamie,
How are you liking your new ride.

They are fun that's for sure.

It's the best! I've never had so much enjoyment from driving a car. Whether I'm on the gas or just cruising, it feels perfect :Woohoo

Here's the torque and horsepower curve:

Here's another:

And another:

Wanna see why is doesn't make torque above 5k? Look at the A/F ratio:

Be careful powershifting in the EVO; the clutch disk is designed to slip.

Actually, to race an EVO, you have to shift at ~5k in first 3 gears and when leaving fourth, you have to rev quite a bit higher due to the massive gap in gearing. Most gearshifts only drop the rpms by 1k~1.5k.

Final Drive: 4.529 <---- Can you say short?

1st: 2.928
2nd: 1.950
3rd: 1.407
4th: 1.031
5th: 0.720

EVO exhaust valves are hollow but the intake valves are the same as DSM.
The intake ports are slightly larger than DSM stuff but the exhaust is pretty much the same.
EVO pistons feature an offset wrist pin, or so I am told by several other shops, for increased longevity and an altered piston dwell curve.
EVO pinout is extremely similar to 2G; the connectors are the same. There are a few switched wires and some additional emissions stuff. The fuel pump has dual mode as per Supra mkiv.
Fuel pumps are similar. Both can use a GSS342 as upgrade although I believe the EVO pump is slightly larger.
EVO's have 560 cc injectors that should drop into a DSM.
EVO has smaller valvesprings with what appears to be the same retainers.

uses same camshaft position sensors and wiring as the newer 2g's.

Based on part numbers...

Timing belts are the same also. will be stronger on new model's coming out (100k change).

Lifters are the revised version and also work in a DSM.

It "looks" like the throttle body would work also, fits the same way a 2g one would. Not for sure though.

The throttle cable is a non-cruise control style and should also work in a DSM. (based on MR)

I will look into the part numbers more... see what I can find.

100K change for the stronger one... the interval is already 105K silly ;) The new MIVEC head for '06 has a reinforced design to deal with the increased strain that should be a nice upgrade if you don't want the PE version.

The throttle body is about 60mm (same as a 1G) with similar sensors, bolt pattern, etc... but isn't worth paying 10 times the market price for something that may fit. I don't know about the associated throttle cable as it's meant to sit on the opposite side of the engine bay. Just go with what fits--2G spyder w/o cruise.

Thanks for the info. My friend just wrecked his. Going to try and interchange some stuff.

This thread is so dated it's not even funny. Don't bother trying to find stuff to swap from EVO to DSM or vise-versa.

You can swap pistons and rods into a 7 bolt w/ no machine work. The BOV is well worth it, holds 20 no problem. Brembos are a nice swap also for the dsms from the evo. many swapable parts...Also if you are shifting you evo @ 5k for racing, you need to work on that. I shift out at 7500 right before the rev limiter kicks in. And my stock clutch lasted 30k so obviously I am doing something right. No Grinds in the tranyy either.

evo rocker arms can be used in a dsm.

Brembos need an adapter bracket to fit DSMs. I just laugh at progress - outside of hp, the spec sheet for an EVO VIII and Galant VR-4 are almost identical. Not to say that the EVO isn't better, but it doesn't look that way on paper.

This is great.. but how can used in a dsm? please provide more details. thanks

Seriously? Bring back a 4yr old thread then ask how to swap rockers. My guess is that they will add 100whp because they are sourced from an evolution.

Send a PM to original poster/moderator, EvolvedDSM, and he will be more than happy to answer all your EVO vs DSM part needs.
