and basically you're saying the GA15 head can rev higher?
The listing on E-bay said "JDM GA15DE", but the pictures showed a GA16I... yes they had pics of a GA16I with TBI.
I E-mailed them and they sent back that it was not a GA15DE they said it was a GA15E. At that point I decided to buy it, and when it arrived it was not like the description or the pictures. What I have most resembles the second one, but without the air box and only 50% of the accesories. I have already contacted them and they offered to return my money, but I have already gone through too much hassle to be picky about which intake manifold it has. I have decided to just use what I have and wish that I had the JDM MPFI manifold
And on the revving higher, I missinturpreted the info on bore/stroke, the GA15 has less bore than the GA16, I thought it had less stroke. So actually it should be the same as the GA16 for the Revvs. Ah well, I still think it will do great in the Pulsar with my MPFI.

ok, reason i was wondering if it would rev higher is if the valvetrain is stronger, therefore handling higher revs. how much did the engine cost you? and did they say you had to pay the return shipping? cuz if not, it may be worth getting the money back and ordering the first one there for the MPFI manifold.

$475 to my door, they did not say about the return shipping, anyway I could just buy the GA15E shipped for around $700, and that way I would have a spare engine...
I'd bet there are several people who have bought the GA15E from E-bay, and pulled the MFPI manifold off, and threw it away, or have it lying around.
As for the Mechanical lifters I do not think that they are any stronger than the Hydraullic lifters, but people who race small block chevy's tend to run solid lifters. I think you get better lift with the mechanical lifters even with lower oil pressure.
In any case it is too late to ship the engine back as I have allready stripped off the manifolds and am getting it ready to drop in the Pulsar.
Got it all together again, and have Just about worked out all the bugs. I am very pleased with the results, and now that I have gotten the O2 sensor loop to close it lookes like the mileage has gone way up! (Looks like almost 37MPG) When I go through the first tank and clock the mileage I will post back with the actual numbers.
I have all the info on the wiring, and the drawing for the TPS adapter, and am compiling a list of things needed to make the whole swap.
When I get 100% complete I will post a full write-up with pictures so that anyone can do this too.

you could mount a sr20de TB on the mpfi intake..all you have to do is bore out he manifold to match the TB...helps with throttle response! had it on my sentra with cams and exhaust..was a blast!
and great job with the Hoe-E-M modification! this is one of my favorite types of modifications!

Does said SR20DE TB hook up to the same TPS and coolant lines? What about the Rubber tube from MAF to TB? I think this might be fun to try too!
I just drove it to see the back pressure; it is 5-6 PSI at the exhaust manifold from 4,000RPM-redline at full throttle. What is considered normal?
I don't really know, but it could be too high, I should do some more research...
I know the pulsar is lighter than the sentra, but it is so much quicker than the sentra there is almost no comparison. I am going to do some more searching and see what I find...
With open CAT it is now around 0.75 PSI max, so I have Identified the problem as the muffler. I will be putting on a inexpensive turbo muffler, and I should gain all the flow back.

i have used this site several times in the past(i am notorious for my side exit exhuast on my b13!)have made couple others...they have good prices and ship fast!

i had to mount the tps in reverse and the coolant lines match(i had done the coolant line by pass mod....) only other thing i had to do was "gently" bend the vacuum line on the intake on the side where the tps mounts and trimmed the connector so it would fit on (was quite easy)
the rubber hose to the tb between the maf i took a sauce pot and heated up about 2" of water to boiling put the end of the hose in there for a few minutes to heat it up and then slipped it onto the tb...its a tight fit but it goes on took two tries the first time to get it right...lol it will hold the shape just fine after it cools down on the TB.
