Nice!

What ever happened to your Colt project?

GRNDSM

Hi guys, I am almost back working on my TR7! Over last few years, I have a few “distractions”. Most notable being my ’93 Summit. But it is now done and I am having a blast with it!

However, before I can resume ...

GRNDSM

Where are you located?

GRNDSM

NM, guys, this isn't happening...

GRNDSM

Hi Guys,

Long time no visit. For the last 10 months or so, I have been focusing on my AWD Summit 4G63t project. But I am still around and my TR7 is "next" in que of projects...

Myself and a couple of other New England DSM members want to test the waters about bringing back "DSM powered" class to ...

GRNDSM

Lets clarify something:

-EVO3 16G is a direct bolt-in for DSM (this a very good and popular turbo)
-EVO8 16G is bigger but it is pointing in the "wrong" direction, so it is vertually impossible to install it in a DSM. However, it is perfect for RWD 4g63 configuration!

Check out my site on my EVO8 ...

GRNDSM

Are those 4 or 5 lug rims?

GRNDSM

EVO8 16G turbos are closer to the old school 20Gs and you can pick them up for around $200, usually with low miles... However, install isn't trevial and it will require at the very minimal alternator relocation (good idea in any case

).

GRNDSM

What's crappy about the stock tranny?

It isn't very strong. 350ft*lbs of torque is about as much as they can take. And being designed for a low revving 2.6 engines, Starion trannies do not like to shift at high RPMs.

Also, to have a fighting chance get the 88/89 tranny, they are stronger and ...

GRNDSM

A typical tranny adaptor plate will cost you $300-$500. Plus, you will have to figure out clutch and starter (since plate will add extra space). What is the point of investing all that effort into a crappy tranny?

If you are going to go through the trouble of adapting a tranny, get something good ...

GRNDSM

You can definitely clean up factory harness to look good!

As for MAF, you can ether go with 2G or EVO 8-9, they look nicer and flow a lot more than 1G. Or you can use GM MAF. Now, you do not even need a tranlator if you get V3 DSM Link.

GRNDSM

Are you saying I should just toss all the DOHC stuff onto the SOHC block, without making sure all specs are within tolerances, or replace bearings and other wear items while I'm in there?

How did you possibly got this from what I said? :?:

I said 4G63T that means a turbo/DOHC motor... Do not ...

GRNDSM

I have seen way too many failed 4G63 "rebild jobs"... unless I know and trust the builder AND the machine shop that does the machining. I would take a 100k miles "junk yard motor" over some random rebuilt motor.

My point, do not rebuild 4G63T, unless it needs it! It is hard to build it better than ...

GRNDSM

The obsolute cheapers way to do such conversion, is to use a narrow-block tranny (from a truck) with Starion shifter extention. But that isn't the strongest tranny... So you will have to keep your 4G63 down to under 300hp or so. And isn't easy to do

.

GRNDSM

With your legs just inches behing the bumper, do you blame them?

I would hate to rear end a truck with this thing

Of course, I woudn't want to rear end a truck in any vehicle

.

GRNDSM

Put me as another vote for DSM link. It is easy and it is VERY effective!

Swapping engines is enough of a challenge to also take on a task of becoming a tuning expert.

GRNDSM

Very cool project, Smog! This beats my Summit wagon as the ultimate sleeper

But we need engine bay photos!

GRNDSM

Nice to see you here, Ron

.

Bill, can we try to have this double as a scatter shield, or do they reject aluminum, no matter how thick it is?

GRNDSM

Thats not just CA, thats any car in general. You can not legally remove OR DISABLE an emission device that is on the emission label under your hood. You can be fined up to $25,000 per vehicle (or maybe per device-- not sure) for this if the EPA so chooses to mess with you. The only exception I can ...

GRNDSM

Nice car!

That is one thick manifold spacer! How thick is it and where did you get it?

I was able to get away with 1/2" (12.7mm) spacer after I ground the block and the turbine housing.

GRNDSM

Thanks!

That is the "Ebay" EVO7-9 manifold that sells for around $150 with 02 housing. I do not think that it will last very long before it will crack, but I do not plan on puttin much more than 500-1000 miles on this turbo. So it should serve me just fine.

However, you can buy much better ...

GRNDSM

The car looks awesome!

I find it funny that front syspension looks just like my 80 TR7!!!

GRNDSM

Yep, I got my first DSM (90 GSX) back in '91. Like I said, it was a very old information

. Long before I even heard about "wide and narrow" blocks!

GRNDSM

You might want to search as this question come-up fairly often. There is really no advantage in EVO8-9 motors over the DSM motors, but they are a LOT more expensive...

GRNDSM

I'm pretty sure the 2.0 Starions were all wideblocks. Not sure where you guys are hearing otherwise.

That information was quite old :oops: Back in the mid 90's I talked to a DSMer from Australia (on Talon Digest) about 2.0L Starions. We both thought that such tranny would work for RWD conversion ...

GRNDSM

Bryan,

From I understand, you have a regular "narrow" bell housing pattern, so you tranny should bould right up! But is should be easy enough to check

.

GRNDSM

Looks awesome, Bill! I gave up on the bulkhead idea, figuring that it will cost too much

.

GRNDSM

The first photo is your charcoal canister. It is a vent for your gas tank and it is mainly there for emissions control (fuel vapor). Many enthusiasts get rid of it, but then you must decide what to do with your gas tank vent. You can ether vent it out (that will cause fuel smell) or plug it up (this ...

GRNDSM

But we got this thing called EPA and government and stuff, with rules and stuff like that, and they like 'bling'

Everyone else got around this by labelling their intakes as "off road use only" ;). Another way to look at it: out of 10-20 companies that make different intakes for DSMs, there isn't ...

GRNDSM

Bill, you will be hard pressed to find a DSMer running a functionning EGR system since the mid '90's (myself included) and I am yet to hear about any problems with it.

As for fuel economy, the last time that I drove my Green Machine to the shootout, I got 31 mpg on the highway (the car was running ...

GRNDSM

As always, very nice work, Bill!

I am especially impressed with the amount of dedication and effort you dedicated to the EGR system, which almost no one uses! I have a fundamental problem with the EGR system: it makes a mess your intake system and it is the cause of most idle problems in DSMs!

I ...

GRNDSM

Well, it isn't about power when it comes to trannies, all they see is torque. And you can build a low torque/high hp 4G63 engine

.

GRNDSM

Dan Buschur (Dave brother), was working on one back in '96/'97. Unfortunately, he abandoned the projected

. But for a while, there were some really neat pictures of 4G63 in a caged knotchback Mustang!

He was going to use powerglide tranny.

GRNDSM

You are going to point at a Subaru as an example of something done right? This is Mitsu forum, Subarus SUCK!

Also notice that any serius Subaru enthusiats convert their cars to a conventional front mount I/C

.

GRNDSM

Really? I dislike it... A LOT!

It looks like something you do because you have to, rather than because it is a good idea. I/C location is also pretty bad.

I would do everything possible to keep stock hood profile! But it might not be possible, depending on hood height.

GRNDSM

Here is a link to the Mitsu powered Spitfire.

BTW, does anyone else find irony in Mitsu powered Spitfire? WW2 reference

GRNDSM

Now we are talking about something very dear and near my hart: 4G63 in an old British convertible. If you guys are not familiar with my TR7 project, check out: www.reitmanracing.com

If you were gong to do this to Sunbeam Tiger, I would say you are crazy for even considering it (sort of like putting ...

GRNDSM

Why do you drive your Miata in the snow?

But seriously, what is the limitation of that Miata rear end?

GRNDSM

Wow, that is a two door sedan! Pretty neat. But I have seen enough friends with VWs/AUDIs which had endless electrical problems, so I would never touch one. And they make fun of British car's electrical systems

GRNDSM

The driveshaft is the easieast part of this project! Just any driveshaft shaft (there are a LOT of them!) can combine two shafts to your length for under $200.

94+ Miata had a stronger rear end and had an option for a decent Torsen LSD.

I have 94 Miata rear end for my TR7 project, but I still ...

GRNDSM

My guestimate is that it will cost you at least 2 times more to adapt an EVO8 engine vs the DSM engine. Unless you just HAVE to have the EVO8 engine, I would sell it buy a cheaper DSM 4G63...

GRNDSM

Looks great, Bill!

GRNDSM

From www.DSMtimes.org

-number of sub 10 sec FWD DSMs: 6
-number of sub 10 sec AWD DSMs: 56

Is that enough of an explanation as to why not many companies offer FWD twin disc clutch KITs ? ;)

Matt, I checked compclutch site but didn't seen any Mitsu (FWD or AWD) twin disc options. Is it something ...

GRNDSM

No, 1G heads do not have such provision. In the mid to late 90's, people used to install 1G heads on 2G fairly often. This was before RRE/Magnus (I forget who was first), came out with a way to wire-in 1G CAS. Anyway, they had to weld in bosses in 1G heads for 2G CAS.

GRNDSM

And do you not get a "base" setting by a verture of installing it?

I am pretty sure he was talking about adjusting it as means of tuning...

GRNDSM

jeffball610 wrote:Pretty cool. Does it allow you to adjust your ignition timing at all?

Why should that matter? By now, everyone should be using DSM Link or some other engine management system to take care of timing

.

GRNDSM

Bill,

Personally, I already have a FWD ACT FW so I would prefer to stick with it. But looking at what should be best for your project, I think that AWD FW would be a better option.

I spent several hours searching and I haven’t been able to find any other twin disc clutch available for the FWD FW ...

GRNDSM

Theoretically, you are correct, Bill. But there are other factors:

The "narrow" feature of the "narrow" engine has not been a problem for anyone, so it is a non-issue. My problem with "wide" blocks is that you MUST start by rebuilding an engine, which automatically adds $1000-$3000 to your project ...

GRNDSM

I just ran 145mph on 2800lbs car using FP 3565 HTA (a varient of GT35R). that takes 600+ whp to atchieve that trap speed.

We tried dynoing the car this past Wed, but ran into some difficulties... We will give it another shot next Wed.

GRNDSM

The narrow block is okay , but the wide block has a taller block and allows the use of longer rods for the higher horsepower levels, so its to the builders advantage to build the wide block with

I let my feeling known about 2.4L engine in another thread, so there is no need to get off topic here ...
