Curious on the reason for the RHD conversion.

That's a pretty big turbo. I'll be very interested to see how it goes on top of the RB30. Should be fun :)

the reason i wanted to do RHD is cuz i go to alot of car shows an it will put me in a diff class, plus ill get alot of attention. an its diff.

yea i know the turbo is not gonna fit im gonna either cut a whole in the hood or put some big spacers in there

Lots of great potential. Here's some questions for ya:

Sorry if I missed it, I'm assuming you're using the 25 head? Are the mounts any different for the 30 block or are you using the 25 mounts? Where/what specifics are you getting done to the head? (who makes the springs/valves/retainers... keeping hydro lifters?) What engine management?

That's definitely a gigantor turbo... but with the RHD, might have more clearance?

Also, any more pics of the import model? And LOL at her standing by the detailing supplies... could probably use her to dust your car! ;)

P.S. It looks like your car might've been saved, if it didn't have that turbo blanket. I had one catch on fire on my 25 briefly, due to a leaky fitting on my Holset, but luckily caught it in time before it did any real damage.

oohh sorry bout that but im using the rb26 head with BC 1mm oversized valves, springs and retainers. im using kelfold 272 cams. the mounts are gonna be a lil diff cuz of the block size but i dont know what im gonna do as far as what i using yet. im using power fc ecu with the car.

with it being RHD i can have a bigger DP (good for :chuckle: )

i have few more pic of diff models at that car show... the car is fine didnt mess up the are anything, luckily but not luckily i was at a gas station, hehe. the turbo blanket was gone tho saved my turbo..

As far as mounts/hood clearance, if you using a stock RB25 sump and Mack mounts.. you can get it to fit pretty decent. I ended up making some 7/8" tall solid pucks on Mack mounts. I have 1/16" of clearance from my sump to crossmember in an S-13. I had to shave my Rb26 aluminum cam cover, cut the supports out of the hood and it still barely touches with the timing cover on... its a tall b****. Now I believe an s-14 has a less sloping hood line, so you should be able to clear with above said mods.

Really there is no other way to get my RB30 to sit lower unless I go dry sump, or make/modify my steering rack/crossmember.

What are your goals for this car? This is a show/dyno queen? a Driver/racer or all of the above?

Nice heels too btw. ;)

thanks for the tips... my goals are to get are 800whp(for dyno numbers, drive around on 650ish) but be a DD and next year get the body done and become a car show ready DD car. i will be racing the s*** out of it tho i love racing so you'll se a lot of vidz from me. and prob a lot of tuning vidz to cuz i love tuning cars on E85.

is your motors stock? what is ur setup?

The reason I asked about the RHD conversion is you will have a lot more room and could lower the manifold's flange with some hacking/welding. Stec who a few of you on here know fit a HX52 top mounted under his hood (S14) with no spacers. He did have to notch the hood frame a little though.

I'm not a big fan of RHD for the "cool" factor, but obviously I'm a little disillusioned to it being here. I guess if I didn't see it every day, it might be different.

well that is a good point on the turbo mani. after all this hard work on the RHD i will not be doing it again i will buy one done if i do it again. i see a few S body but more skylines. which are highly illegal an dont want mines taken up. as far as a head turner thats what it will be. but b4 when i was thinking about doing it alot people didnt agree with doing it but, its one of those things that i had to do it to say i wish i woulda did it, you know??

Yeah your right, you have to design your own. :) If you ever want I can get you a set with the specs I used.

Honestly the car is running GREAT roughly 3k hard miles on it after the rebuild. I need to get back to the dyno since I recently made a new 3.5" turbo back exhaust, the car took another 5-10% VE from 4800-7000 rpm to maintain my previous 11.2-11.4 a/f. I might be going next week as long as the weather forecast stays nice. (my ET streets are pretty bald)

My turbo got so much more responsive with the ~.3liters of added displacement from where I was. I'm considering pushing the stock rods in the spring with some e85 and another ~8 psi. I will see.

How long do you think till you start her up?

did you get your crank balanced? how big is you current turbo? u still on 20psi? you will love E85, i have not been back to pump gas since 2006( in sports car) the power and torque diff is def felt. im hoping to get her started in like 2-3 weeks im hoping to get motor in car by next week. i have it wired for LHD and now have to go back an rewire for RHD then wire the chassis aswell then that should be it, i hope.

Cranks not balanced just pistons and rods. I run a PTE6765 cast wheels (its older) yes still at 20 psi boost cut is at 21 I'm running an internal map so I'm clapped out right now, until I get a gm 3 bar external.

J2fast and Shocker, did both of you use the stock S-chassis crossmember, or swap in 1 from r32/r33?

Anybody know the actual differences between the RB30, 26, and 25 blocks? (could possibly just build a stroker from the others to 27/29?)

im using the r33 gts crossmember which i believe is the lowest Nissan crossmember. the blocks are diff sizes from 30 and the 26/25.

Your gonna either need to cut a huge hole in your hood (not ideal) or get a new lower mount/ forward facing manifold. Dude you have an extremely custom setup ditch that manifold and get a custom one made to fit your setup.

well im back an finally got things back going again, came to a stop due to couldn't find motor mounts and shims. so i got some shims( thanks to rawbrokerage). so motor is put together now. i drop the motor in the car and had issues with trying to get the tranny to line up( rb26 tranny). got that fixed. the i went to the local auto store n found the smallest mounts they had and they are gonna have to work. now im in the process of redoing all my plumbing, then i have to redo my wire harness for the RHD wire harness. ill post some pictures up when i get back to the shop tonight.
