13G on a 420A

[Heartless]

First off I have spent the morning searching and I was not able to find any info on someone installing a 13G on a 420A. I have an extra 13G laying around off of a 1G auto and was thinking about putting it on my 96. I know everyone is gonna tell me not to waste my time and get at least a 14b but I already have the 13G and its free! So my question in being is: would it be reasonable to run 10psi on a stock motor (with 115,000 miles on it, good compression, and a recent headgasket change)without any problems? (also assuming I get at least an FMU if not an SFMU)

I wouldnt run 10psi. Run up to 8psi and you will be fine. I would use the 13g since you already have it. You can always swap it out for a 14b or 16g if you ever want to upgrade. Go ahead and get the SFMU. The FMU are crap and dont work well at all. I was able to get a pretty good tune with the SFMU and some 310cc injectors.

Thanks for the info I'll get the SFMU and some 310 injectors and get started!

Sell the 13G on eBay and find a good used T25.

The turbine housing will flow much more because it's 6cm2 versus the off-centered 5cm2 of the 13G (better for the 9.6:1 compression on the 420A), and the T25's compressor housing can be clocked 360* if you redrill the holes for the wastegate actuator. The T25 also doesn't require a j-pipe on the compressor outlet, and a piece of 1/4" metal brake / fuel line can be used for your oil supply line (no banjo fittings).

I've been kicking around the idea of boosting my GS using a T25....if not, I'm going to look for a clean 2G GST this summer for a daily driver; although I enjoy the cheap insurance of the GS!

The t25 sucks. Why the hell would he do that. I think the 13g is better than that. And if not it would be easier upgraded to a 14b or 16g. Much easier than upgrading from the t25

true ...T25 is not the best turbo by a long shot for DSMs...

but flows so littile, it perfect for the 420a....

but since you have a 13G stick with that...

you can find install kits 14B online easily...
