got my T1 turbo's today!!! these will be rebuilt and heat coated hot side and powder coated in the boost side!

I pulled my pistons today. and as I expected the ring gap was to small!!! only 0.012 inches! new rings it is!!!
Well if they are too small why not just open them up to where you want em? Aren't you going with file fit rings anyway?
i assume the block is getting honed anyways? good looking out on the new rings. Also, if i had to make a guess, this is a 10:1cr engine. low boost or alky injection would be required. That or running race fuel or e85.

2 small t1 turbos might work alright but i dont think they will be happy in the upper rpms. Remember, each one of these turbos will be driven by 1.75L. Thats right about honda territory. I know honda guys would never be caught dead with a turbo that smalll. Why? Because they are reving pretty high and make more power than a NA 2.2 ever made.. so they require a bigger turbo.
Im all for trying twin t1 turbos, even if they are a little bigger than the stock VR4 turbos. Something to remember is that the g72 quickly maxes out the stock VR4 turbos.. and that is a 3.0. You have a 3.5L.
I love your intake and i support the 52mm throttle bodys but i dont support 2inch pipping and small throttle bodys in the name of keeping velocity up. The velocity will be there even with 2.5inch piping and 58mm throttle bodys.
Eds car has bigger intakes and 80mm throttle bodys. We drove that thing for a week straight all across the country. That being said, it was really responsive to throttle tip-in but if he can do it with twin 80s, i think you can handle twin 58mm or even bigger. I think 60mm throttle bodys came on the 3000gt and 4g63 motors. You will make more power in NA form with the bigger throttles and your turbos will spool earlier as an effect.
anyways, i dont think you will see the power you would like to see if you stick with the t1 turbos. 3000gt guys build the 3.5 all the time. You are blessed to be able to follow their footsteps and see what they do to make what power. The car will be a riot either way but i think it will be a torque machine that chokes out in the high rpm if you do stick with the smaller turbos.
well the goal is a cruzer/part time drag car. I really don't want to go high up in the RPM range. I just want a fun car to drive and the twins are more for show than go!LOL yes they will be good at stop light jumping and also at my 1/8 mile drag strip. I just thinkk it will be a fun car to drive!
my worry is that they might spool to soon
it's all good. the turbo's and BOV's were free!!!! and if I don't like them the car will be set up and a turbo upgrade will be a simple swap. no loss but plenty to gain!
I haven't made the measurements yet, but I think we can increase the size of the combustion chamber and drop that compression ratio some... I know the 24v SOHC heads respond REAL well to unshrouding the valves. I suspect the DOHC heads will as well.
and that Ed is why your getting my heads!!! port polish and combustion chamber mods!
I am so glad I replaced the rings in this motor!!! cyl #1 and cyl #4 were so carboned up that the top ring was locked into the ring land! it took a bit of work to get the compression rings out without damaging the piston. other than that all is well. I file fit the rings. .035 on top and .032 on the 2nd. now I have a great deal of cleaning to do before assembly!!!
Looks like the head gasket was leaking,I pulled my pistons today. and as I expected the ring gap was to small!!! only 0.012 inches! new rings it is!!!

yea, it was!!!LOL that kind-a happend when it lost it's timing belt!!! 20 of the 24 valves were bent!!! pistons survived!!!I was amazed!!!Looks like the head gasket was leaking,
I bent all the valves in my SOHC 24v and the pistons were barely scratched. Piston > valve stem lol
LOL!!! yea, I had a couple of valve stems that were shaped like a "Z"!!! had to use a hammer to push them back so i could get them out! now I need to just install the new guides.valves,and seals. then get Ed to port them and I am done with the long block!!!!
Rockauto.com FTW on those parts. I have all new valves ready to go for my 2nd set of heads for cheap.
yea, I got mine too! valves, guides, and seals. as well as a full gasket set. just have to save up for the heads. I will also have Ed port my exhaust housing on the turbos.
A note on this. For a while I ran twin 58mm TBs and they were MUCH touchier than the twin 80mm TBs w/progressive linkage...
i bet the progressive linkages are what helped. stock 58mm's would have a stock linkage profile so I could see it being touchy.
I'm not seeing how those turbos are too small... yet. I've convinced myself they're a good size in pairs. I'm curious to see where they spool. If boost is coming in at 4000+ on a 3.5 motor, I may rethink using them on a 3.0.
For my sometime in the future N/A twin TB build, I'm just gonna use a pair of 48s I have, those should be "enough" really to hit 300HP or so, and I doubt my build will gain more than a hp going bigger unless I'm close to 300ish. I'm aiming for mid 200s and perfect DDability still.
I have an early motor and late motor, slider cams fatter rings, and roller cams thinner rings. I wanna just port the roller heads for N/A and slap those on at first, and rebuild the later bottom end, possibly stroking it a bit to 3.2. Then the earlier bottom end, which also might be lower compression (though you know how accurate all this stuff is) may get built for turbo duty, since it has beefier ring package. Also I can do some trick sh!t with the slider cam, like fatter followers... then that will be looking for a vehicle to live in.... possibly something that didn't got a 3.0, like a lancer, or something comfy like a dysentry, or maybe a 2nd gen AWD van.
DD1: '02 T&C Ltd, 3.8 AWD. DD2: '15 Versa Note SV, replacing.. DDx: '14 Versa Note SV << freshly killded :( ....... Projects: '88 Voyager 3.0, Auto with shift kit, timing advance, walker sound FX muffler on 15" pumpers wrapped in 215/65/R15 H rated Nexens.... and a '95 phord escort wagon PnP head << Both may need to go :( ..... I like 3.0s ... so??? ... stop looking at me like I've got two heads!
I may be forced to use a single throttle body. as this motor keeps coming together less and less room become availible. so i may not have to worry about it.
