adjsut the clutch, find some real clamps, replace the starter (sounds like a clutch issue) and re-adjust the throttle cable, where it attaches to the intake manifold, so all the slack is out of the cable, but yet not pulling on the cable. You'll be set.

Re: Make slowboy not so slow
 
I don't know about dsms' throttle cable, but you should leave the adjustment for the cable-jacket loose, let the car warm up then tighten it down with a little slack in the cable itself. Maybe when the car warms up, it's tightening up the cable enough to let the TB hang open a bit. just a suggestion.

And working out the bugs after doing an engine swap is the best part, because the hard work is over!

Yea we did that with the cable. I think the throttle body is sticky and wont close all the way. Also the FIAV might be crap, so I would try another throttle body and see if that fixes the high and bouncing idle.

We made lots of progress on the car, and Im glad it started... Ive never heard a race motor before but should they sound any different than a stock motor? It seems to be more buzzy and mechanical sounding. Its hard to explain, it just doesnt sound as smooth as it should.

Best times were definetly at the bars and not in the garage. haha

I had the same issue with the throttle cable on the 6 bolt swap I just did. They must get positioned slightly different and I had to move the throttle cable in slightly at the cruise control unit. I was out of adjustment at the cable mount on the intake manifold. It just barely wouldn't close all the way.

Solid lifters as opposed to hydraulic? I know nothing about 4g63 heads.

Re: Make slowboy not so slow
 
He reused his 2g lifters, I think the head only has a massive port and angle job along with oversized valves and diff springs. The block is built too though.

I have plenty of adjustment on the intake mani bracket, maybe 1/2" either way right now. At first I had it too tight so it was stuck open at 1 or 2%, then we loosen it up and it goes back to .1%, I'll try loosening it a tiny bit more and use more pb blaster on the springy thing that was sticky before.

As for replacing the starter, I'm pretty sure it's not bad. It's the same one that's always been on my car and it never did that once ever, so I think there's something wrong with the way I put it back on maybe.

I think the throttle body may be bad as well. My friend gave it to me for free, but it was really dirty when I got it, plus I think it was too close to something when he was porting, because there were little metal shavings on it before I cleaned it up. Maybe I'll get a new one from TKR since he has a few for sale if nothing else fixed the idling issue.

Re: Make slowboy not so slow
 
make sure its on there straight, or that you used 2 bolts to hold the starter on..

Re: Make slowboy not so slow
 
Good to hear man!

Like JET said, play with the adjustment of the cable as it mounts to the IM. I remember on my car having to do something goofy as well, but nothing crazy. Also if the car has cruise control, play with extra mess of throttle cables that mount just behind the TB elbow, mine got schmucked when the 6-bolt was going in and it caused similar issues to what you are describing.

asshanson 12-17-2007 01:38 PM

Re: Make slowboy not so slow
 
Just started it up again after going to lunch, so the car was basically warm from the trip there. Anyway, it started right up and idled at 850rpm. Also, the clutch pedal keeps grabbing higher and higher each time I drive it, maybe things are getting broken in and adjusting slightly? Fuel trims adjusting which may affect idle? I'm just throwing out random guesses here.

The throttle seems to go back to 0% every time now, hopefully it stays that way. Since several of these parts haven't been used in 2 or 3 years, maybe they just needed a little wearing in.

1ViciousGSX 12-17-2007 06:20 PM

Re: Make slowboy not so slow
 
Check your clutch rod adjustment, 2g's are notorious for ghost pedal which will cause it to pump up.

asshanson 12-18-2007 02:43 AM

Re: Make slowboy not so slow
 
Well I risked the 4 hour drive back up to the cities, and the car made it. Not without a couple problems though. First, I think my valve cover is leaking really bad, it started losing oil somewhere on the timing belt side, so I have an oily engine bay on that side now. I had to put in a quart half-way up here. It may just be a gasket issue, or the valve cover may be warped too since it didn't fit quite right on the new motor, rocked a little back and forth without screws.

Also, I'm having a super weird problem with fuel, and it seems ECU related. Under mild acceleration or < 5 lbs boost the car operates great. However, it starts to act up big time when it stays constant throttle for more than 10 seconds or so, then something triggers and it runs like crap. It gets really bogged down it seems like, and shudders a lot, and I thought something in the drivetrain was loose, then noticed my A/F gauge was stuck at lean, not blinking back and forth like usual. Giving more gas and trying to accelerate doesn't fix the problem, it's stuck in this mode. However, putting it into neutral for a few seconds, the light blinks to rich for a second like usual, then i can shift back into gear and cruise normally. A few seconds later, it suddenly triggers back to crap mode. However, if I constantly fluctuate the throttle a few percent, it doesn't get into this mode. Any ideas?????

Re: Make slowboy not so slow
 
This stuttering problem sounds like the issue I had with my car and ESchwanz continues to have. Pull power to the ECU for a minute, then it should go away for a while.

FattyBoomBatty 12-18-2007 09:17 AM

Re: Make slowboy not so slow
 
could that be from a really bad TPS?

FattyBoomBatty 12-18-2007 09:52 AM

Re: Make slowboy not so slow
 
I'm actually also wondering about your grounds. Seems to me that things attatched to your engine aren't working properly, perhaps the engine isn't grounded very well? starter engaging and disengaging and other weird problems. I dunno.

Thanks, I'll check them, that sounds pretty reasonable actually. I had one leftover ground cable when I was done, not sure where it goes.

Also, is the TPS adjustable, sort of like the CAS? Because when I bolted it back on I just put it to the middle of the slots, not sure how to set it correctly.

Halon 12-18-2007 05:22 PM

Re: Make slowboy not so slow
 
If you have a means to log, you should be able to adjust the TPS so that at full throttle you see 100%.

asshanson 12-22-2007 07:39 PM

Re: Make slowboy not so slow
 
Got the oil leak fixed, found out I had a bad valve cover and MAP fixed it all up (also realized I forgot to switch the injector pins). The problem with the stuttering/lean mode went away for a day, but on my way back home today it happened again. So I disconnected the battery power for a minute and it fixed the problem. This is going to be annoying if I have to disconnect my battery every couple of days. Scheides, did dsmlink fix the problem on your old 2g?

My gas mileage is so awesome now, I love it. Normally I got around 270 miles per tank, I'm at almost 300 now and it's just below the quarter full mark. Granted it was 100% highway, but I'm guessing it'll turn out to be 28mpg or so, about 4-5 increase.

Also, when I used to cruise on the highway, it would sometimes have to get into a pound of boost to maintain 75 up a hill, but now it never gets above the 10 in vacuum, maybe why I'm getting better highway mileage.

Anyway, just need to fix the high idle and adjust the throttle position sensor now, plus little things like a boost leak test. It's still pretty driveable in the current condition though, it'll be a few weeks before I get to fix everything.

Re: Make slowboy not so slow
 
Glad to hear its running better for you boss!

asshanson 12-26-2007 01:19 PM

Re: Make slowboy not so slow
 
Confirmed, I got 28 mpg on the way to Iowa. Since the roads were bad my average speed was probably 60, on the way back the average was probably low 70s, I think it'll be about 25 mpg, which is still a few better than before.

Anyway, I was wondering about the MDP (or MAP) sensor. A few people have told me to keep it until I get dsmlink, but a few have said it's not necessary. I did some looking around and RRE and a few other places say it's just for EGR monitoring, which I don't have any more. A few other places say it's for idle control.

What I'm thinking is I didn't seal the vacuum line to the tiny MDP sensor nipple and it caused a huge boost leak (P port of TB), which may explain why my car doesn't want to idle below 1300rpm. Any thoughts?

Re: Make slowboy not so slow
 
I never fixed the stuttering problem with my 2G; I never had DSMlink to play with, I ended up selling the car before that was fixed :(

Boost leak test is a BIG thing, not a small thing. Do this sooner than later--you're welcome to come use my air compressor and tester if you want!

JET 12-26-2007 01:23 PM

Put a screw in the hose to block it off.

I hope a new ECU and dsmlink fix it I guess. However, I think I will take you up on that boost test offer after I get back from vacation.

Maybe tomorrow I will cap the TB ports and see if that fixes the idle (or see if the car works fine without the MDP sensor attached).

asshanson 01-08-2008 02:06 PM

Re: Make slowboy not so slow
 
Ok, so the guy who sold me the motor is trying to get out of cars completely, so he wants to sell me his mildly modded 95 gsx (exhaust, fmic, few gauges, etc). The car comes with all of his Mitsu parts, including a shep tranny, a big holset turbo, and a bunch of random parts that I don't know what to do with but could sell eventually.

He's letting it go for dirt cheap, but I don't have the space for an extra car for a couple months while I steal parts off the car and return it to almost 100% stock and sell it.

Anyone willing to rent a garage spot to me for a few months while I work on this thing? The closer to downtown the better, but that's not a huge deal since it would be mostly weekends I'd work on it. I'd probably pick up the car mid January.

FattyBoomBatty 01-08-2008 02:47 PM

Re: Make slowboy not so slow
 
check warehouses around you. I'm storing my car in an old warehouse here in moorhead for like 35 bucks a month, plus they let me work on it. If there was something like that near downtown (there must be something) then I'd do that.

Thanks Pete for renting me the garage spot for a few months. It will be great to have a real spot to work on the car(s).

So I'm ditching my s20g for something bigger now that I have the 2.3 motor. I've heard a lot of people talk about the 60-1, 61, and GT35R. How quickly will these spool on my motor (9.0 compression)?

Thanks,
Andrew

Which one? I hate the numbering places some places use. It should be like SCM6176RHPS, SC6169RE or something like that.

asshanson 01-11-2008 04:27 PM

Re: Make slowboy not so slow
 
How does a GT35RLSP compare to those two?

Is the 2nd number the exhaust wheel size, like 76mm or 69mm, etc?

JET 01-11-2008 04:36 PM

Re: Make slowboy not so slow
 
Those are just 2 examples, there are a ton of different numbers. SC means garrett style housing, SCM is Mitsu housing. 61 is the compressor wheel size, 76 is the exhaust wheel size. The end numbers describe the housings, ported, size of housing, etc.

Shane@DBPerformance 01-12-2008 01:57 PM

Re: Make slowboy not so slow
 
PTE used to make a GT3561 turbo and it used that numbering scheme. It wasn't one really sold much or usually listed for sale. It was pretty much a real non-ball bearing GT35R, not part of the normal SC61 family. GT35R exhaust wheel, GT35R/61mm compressor wheel, GT journal bearing center section. Momin has one on his 1G.

Re: Make slowboy not so slow
 
buy mattd's setup!

I would stay away from an internally gated setup, they tend to suck on pump gas. Plan on dsmlink at the same time. I had an internally gated gt35r on my 2g and it sucked, especially with an afc. On boost onset, it would spike an extra 3 or 4 psi and then settle down to where I had wanted it. This spike would cause knock if set too high, greatly limiting the amount of power the car would put out on pump. With link I probably could have pulled out some timing tocut that down, but ultimately an externally gated setup is 100% the way to go.

asshanson 01-14-2008 11:31 AM

Re: Make slowboy not so slow
 
I picked up that car last night, didn't go so well. At first it was driving fine, but then on the highway the battery light, check engine light, and brake light all came on at once for a minute, then they all went off. I thought it was strange, but kept driving. Occasionally they would flash for a second, but remained off most of the time.

30 miles down the road the car just does a clunk clunk and dies hard. The motor supposedly had rod knock so I thought the motor was toast, but now I'm thinking maybe the alternator was dead. The lights were pretty dim too.

I'll know in a week or so when I get the motor out i guess.
