4G64t in a 90 MM. Cranks won't run.
DSMLink is installed
I have fuel pressure, I have spark
is there something I am missing with the 4g64/4g63t?
I have the timing marks set on the head as stock and the block tdc
I have a 5degree reading on dsmlink for timing when I crank it over
-Thanks Ryan

90 mm bottom end/94gsxhead
The question is - Where do I set the timing marks if I am using the gsx cam gears? My understanding is the marks are a tooth or two off...??

Not up and running yet

I actually just got the block back from the engine builder as there was a bearing problem. Then we had a bolt for the mains snap... but it should start going together next week, I have a feeling it will be a while with many more issues before it is up and running...

For some reason the early first gen was not available anywhere I only found one place that had them. The 90-92's are larger than all of the later years.

Thanks, I did finally find some. Hard to believe no one had these things! Not even ACL or Clevite direct...

I need to find first gen bearings main and rod- 1990 4g64 can anyone direct me to a site or store that has these? I'm running out of places to try

My legacy had a similar issue and the problem ended up being a toasted turbo- there was a ton of play when I checked the impellers. I would check there.

THANKS Mike!!

F1 racing offers a stage 2 and stage 3 clutch for the trucks stock setup, has anyone tried either of these?

Mike, Do you have a part number or what the original vehicle would be used as a reference? I just need to make sure what I get I can remember how to find it a year or two later when I need a new one since looking up a mighty max wont work lol. Thanks.

As for the 500hp - I am talking bhp not whp and ...

NJ, and what I should have asked is based on my research, is it really as simple as using a stage 2 starion 2.6 clutch? or am I way off?

Can anyone direct me to how to search for a clutch?

Thanks!! That was what I was hoping to hear.

basically I have found 590cc is bare min for 300Hp and 880cc is bar min for 450Hp (these Hp ratings would be at the flywheel)

So the question stands- can I run 850cc or 950cc and run well tuned down to put out about 250-300Hp

economic yet good performance

The DSM link allows for toggle between ...

prob should have posted in electrical....

I live in an emission control state. I am not sure what injectors to run.
I see guys runnin 510's up
I have big 16g, front mount, and most likely going with walboro 255

I was thinking of a few options but not sure what the effects would be on

A) driveability
B) emissions standards
C) Hp

options ...

This may be turning into my build page lol. wiseco pistons ordered and on 4 week delay, eagle rods are on the way as well as acl race bearings.

parts are the hold up- pistons are now special order 4 week wait- and just found out this morning that crower lists the rods but does not have them so now I am working on the eagle rods, should have an answer today.

I am also in need of the 94 galant parts.

Trust me I want it done already and the ...

Great info. Thanks!
Here is a link to the rods I am looking at and the company I have been dealing with...

its a 90 ram 50/MM so 6bolt wideblock, ended up going with the wiseco pistons with 21mm pins (6bolt) and just heard back from crower that the 4g63 6bolt rods will work... I am just worried about rubbing issues.

Thanks everyone, very helpful- think I'm sold

use these, they have held up very well for me. they're in my Blue motor and now they're in my Red motor. My machinist changes the small end bushings while they were out.

Thanks for the ...

I take it you are planning to install a dohc head on the 4g64 and turbocharge it, correct? If this is correct, you can use aftermaket 4g63 rods w/o any issues, unless the bottom of the cylinders need to be clearanced. What Mike was saying, is that if you use a 4g64 crank in the 4g63 block, you will ...

I am thinking of using DSM Link ($500)

any opinions?
cost and user friendliness are my main concerns...

-Crane

Ok so in order to avoid rubbing issues I need to use the stock 4g64 rods? What is the power limit of stock rods? I want reliability and driveability but still kick some ass.

The truck so far-

Air ride with link suspension in rear
Stereo with 9.2 cubic foot enclosure
GM mirrors
custom hood ...

I have read many things on here and other places on the web with conflicting information- Rods?

Are the 4g64 rods the same as the 4g63t rods? I hear yes... but I also hear the 4g63t rods on some builds rub the side walls... I am trying to order some crower rods and noone seems to have an answer on ...

Personal update, visa/mastercard loves me. Ordered Wiseco pistons, crower rods, and 16g turbo upgrade.

Most likely going to use DSM Link considering the price.

still need thermostat housing and galant parts

Sorry for no pics keeping the project under wraps- its a 90 ram 50 with air-ride and BIG ...

Does anyone have a part number for the 4g37 thermostat housing? I am having trouble locating one.

I have a 1990 MM and wanted to know if anyone has tried to run a stock bottom end with the 4g63t 1g head? Between finances and wanting to show the truck this year since paint should be done in the next month. I was thinking I would do the bottom end during the next winter. Has anyone done this? I ...

OK great thanks for the info

Thanks for the info. So your saying the 2.0 ecu will work fine on the converted 2.4? Won't the ignition timing be off?

Hey everyone/anyone,
Ive got a 90 d50/max 4G64 narrow and I picked up a 94 talon 4G63t head but before I go on and start getting more parts to do the swap I need help to figure out what ecu to use. Im in NJ and we cant get around state inspection plugging into the factory ecu to keep it street ...
