Upgrade path for a pre-modded/new to me VR4...

[MrVito]

This thread is intended largely for me to jot down things that I think of in odd hours of the morning, and hopefully will see some insightful input that I've not considered, so please, comment away.


I'm picking up my Galant VR4 this weekend, #1102/2000. The car has a freshly rebuilt head (had a chip on one of the valve in cylinder #3, new valves, valve guides, etc), new timing belt, still has balance shafts, new BS belt, new HG, and all other associated work with removing the head. It currently has an Evo 3 mani, slowboy ported 16g w/ 34mm wastegate, ported dump tube, 3" dp, tp, exhaust. The car comes with a brand new 2g maf uninstalled, and is running on a n entirely stock fuel system. The clutch is shot, and is the first thing on the to-do list for the car. Car also has a new clutch pedal assembly, clutch master and slave cylinders.

I don't intend on doing anything ridiculous with the car, I would like to eventually run 12-14 psi for daily driving, and have a high boost setting of 18psi. Before running higher boost, I fully intend on getting a wideband and datalogger though.

I'm currently trying to decide between the ACT 2100 and 2600 clutches, since the car will see very limited track time and will mostly be a daily driver. I will of course be doing a new pivot ball and clutch fork while the tranny is off, no point in having to pull it again later right?

I'm also trying to decide if I should just pick up a set of 550cc injectors, a Walbro 190, AFPR, install the 2g maf, and run the car like that, or pick up some 650's, afpr, Walbro 255, and a DSM link. As far as searching has shown me, I'll be fine with the 550's on the 16g at stock boost levels, but some people have stated that I'd be running rich at idle. Since the car is likely going to be a daily(ish) driver, I'm leaning more towards larger injectors and the DSM Link both for peace of mind, and an added "buffer zone" as far as fuel supply is concerned.

I'm also wondering if the DSM Link/ 650 combo will lead to better mpg for the daily commute as opposed just running the 550's with the 2G maf, any ideas/opinions/experiences in this department would be greatly appreciated.

Will post pics and more info on the car after she comes home!

(I don't think I violated and of the "Newbie Posting Rules" with this thread, however if I did, I apologize in advance)

After more searching, would 650's or 750's be a better option if I go with the "larger' fuel setup, as I'm not sure I'd be able to keep from going higher than 18psi after getting to drive the car with more power. Going fast is a wicked temptation, but I'd rather be cautious and not melt a motor.

If you do plan on getting link there is no point in getting 550's when you can pay a little more for some 7's or bigger and have them idling like stock with link.

Cool thank you, that is what I was wondering.

I'm waiting to actually post on there until 1102 is in my possession, we're doing the title/keys today, but I have to wait until this weekend to go get the trailer to get the car. Pretty sure it's the pivot ball that is hosed, since right now there is almost no clutch pedal resistance and can only shift her while shes turned off, ie, no driving her home

We ran up to 26psi on the Evo16g with 750's with no issues, so I'd say for your goals those are more than enough. As far as MPG goes, I'm not entirely sure what effect DSMLink would have. I know that the "tuning" you do with DSMLink does not take effect at partial throttle, but I am almost positive that the global settings do take effect regardless of throttle position, as DSMLink'd cars can idle and drive like stock with larger injectors. I'll go out on a limb here and say that the Link/650(or 750) combo would give you similar if not better MPG than the 550/2gmaf would. Definitely do the pivot ball/fork maintenance while you have the tranny out, no reason not to. You might also want to consider removing the balance shafts, not only do they rob power, but if your balance shaft belt breaks it can take out your timing belt with it, which is, needless to say, a huge pain in the ass. I never found the 2600 to be that stiff of a clutch, but then again my civic DD clutch felt like a toy compared to it, if you really are keeping boost levels/power output low like you said, a 2100 should be ok, but there's always the issue of what happens when you want more .

I don't you broke any rules, BTW. Coherent sentences? Check. Paragraph structures? Check. Punctuation? Check. You're already following more rules than about 80% of posts in this section

Awesome, thank you very much for the info. I used to have an Ogura Twin Disc clutch setup on one of my SR Swapped S14's, and I'm thinking that the pedal would probably be about the same as the 2600, but I've no experience to back that up.I do think that some of our local DSM guys are running the 2600, I'll have to talk with them and see what they think, thanks again!

When I had the 550 injectors in with 255 pump and N/T FPR and the 2g MAF I got horrible gas mileage. When I upgraded to 1000cc Delphi injectors with DSMLink, there was no comparison. They idle like stock, the forums are a ton of help, and drive like a completely stock car until WOT.

I have a KYClutch 2600 pressure plate and 6 puck ceramic disc in my GSX and I drive the car daily with 20 psi and the only complaint that I have is the ball of my foot gets a little soar after a long cruise/drive with some buddies or in heavy traffic.

Well, Bill of Sale and title have been signed, the car is now legally mine! Just have to see if I can borrow a friends truck and trailer now to get it across town

My Boy just picked up a 91 Belize green 637/2000 and he got the Original Key Fob with it .........

WOW! The key Fob's are VERY hard to find, I have been told that there is someone to contact to get a new one issued, but I have no idea who/where this person is. Is your friends car white, green, or black?

 

[TheBoz]

The Key FOB is the coolest. I wish my car came with one. Check out the GVR4 forums you will find all the very specific info there. Good people over there also. Congrats on the buy.

Theres a Guy on Galant vr4. that makes replica's, key fobs AND dash plaques. uhm My friends car is a Belize Green 637/2000, my other friends is 74/2000 Nile Black, and Mine is 352/1000 Summit White
