project M30 TT

[ttinfinitiM30]

thanx for the direction. if im not mistaken then this is the device that allows the fuel pressure regulator to run on a vaccum line even with a boosted engine. since there is boost instead of vaccum inside the engine it reqires a different way to power all vaccum operated items. like the brake booster needing a one way valve in the vaccum line to allow the vaccum to remain in the booster and keep the boost out. this just adds to the list of things ill need to get

[infiniti m300x]

you need any part #'s let me know

[ttinfinitiM30]

well i spent some time at the junk yard looking for racks. what ive concluded is that ill be going for the Q45 rack. its angles almost straight back so i should have plenty of clearence around the turbo, it might be a bit in the way of teh down pipe but far enough away to allow a custom downpipe to fit. havent gotten it yet cause the bolts are froze tight but itl only cost me 25 from the yard cause its a U-pull it yard. i jus need to get back there with a big a$$ breaker bar and 22mm socket to get it free. as for the mounts i still havent had any lucck getting a hold on j30 mounts. emailed the few ppl parting out their J's on this site but noothing material yet. if ANYONE has mounts they can part with please let me know. till then ill jus be waiting

[infiniti m300x]

I found some mounts on ebay for 120 shipped. I can give you the info if u want it

[ttinfinitiM30]

thanx but right now i got a set on the way for 35.

[ttinfinitiM30]

update....

i got a set of j30 mounts... they mount up like they were ment for it. the thing i gotta do now is grind off hte little alignment nub on the metal part of the rubber mount to make it fit o so pretty

here... see

its a little close to the turbo inlet but 95-j30t got his working so no biggy.

unfourtinatly i still havent gotten another rack yet so gonna wait for that b4 much other work gets done. besides i got another project that is keeping me busy for now. i wanna finish that b4 any other big work on the TT.

[95-J30tt]

i have an idea that i came up with over the past week for the turbo exhaust hitting the column, i think it would work for both setups, i havent tested it yet but i will try it next weekend....... i'm going to take out the turbo exhaust, and take it to a muffler shop, and get it redone to fit around the column, so basically i'll be redoing the downpipe on the driver side.....

for your setup, i think the best way to go about that problem is using the same method, but hook up two pipes (one exhaust pipe on either side of column, in a shape almost like an O around the column), i'm not sure if i'm making sence, or if that method works.... but take a look at the steering column and find out a way to get the exhaust around it from either side

i think that this method would save money, and might very well work if it is done right, but make sure you put a heat shield on the custom down pipes

[ttinfinitiM30]

i think that would look really cool but would b realy hard to make, and as the engine rocks around... there would need to b enough room there for that to happen. my origanal rack sits between the exhaust and inlet housings of the turbo. dose the j's rack angle more to the rear?? the m30s is relativly upward

theres a guy over seas that did the TT swap into a 240. he sayed he made a custom down pipe to solve the problem. his post is in the 240 section somwhere. but i think ud be fine with a custom downpipe. thats gonna be my plan caus i dont think ill find any exhasut for my car and this engine

[95-J30tt]

any updates yet?, i cant wait to hear news about your project man, i hope that all is going well

[ttinfinitiM30]

srry guys nothing new for the TT. it got cold and i hit the hibernation button on my alarm clock.

my other project is moving a bit faster tho. its a mazda mx6 that i hit the wall with after a tire blew out in the middle of a high speed lane change. im welding up a semi tubed front end on it. jus for the damaged areas. im looking to have that complete b4 much more on the TT.

ill be posting as soon as i get another steering rack for it, one from a j30 or one from a Q45. altho i tihnk they might b the same. teh delay is that the Q45 one i can get for bout $20 from a u pull it yard and the j30 is bout $60 from a they pull it yard.. im not wanting to spend the extra to buy somthing as a test fit and that may jus go bad after 100miles. so im waiting for warmer weather to get the $20 rack. someday ill finally see the light. but till then ill jus be hiting the snooze on that clock.

You can easily find out the year of your motor, just get the engine serial number, call up nissan. they have a database. they will tell you exactly down to the date it was manufactured. thats how i found out i had a 92

heres the story im not 100% on what year engine ive got. so ive been looking at the 1994 FSM and most of it has been linning up. it lables the PRVR control soledoid valve to be what it is. and yes it is yellow with a black/red.

the maf pictured has a 4 pin setup like the schematic decribes so im gonna try it unless someone who knows says otherwise. in that bunch i have 2 black wires 2 white wires and 1 orange wire. the black and white wires are for the maf but i havent found out the orange. im thinking and air inlet temp sensor.

and theres another set of four wires that im unsure what they do, there not found on the 94 scematic so im thinking its older but also dont have a good copy of the earlier diagrams. its located on my first pic of the harness underneith the blue I in INJ. its got 2 bk/rd wires, 1 G, and 1 br. its also located on the back side of the engine pasenger side. (sorry dont have a better pic)

thnx for the help

Whats up guy? I hear you on the whole hibernation thing. I just ripped into my M today. I now have the engine bay soaking overnite for a major powerwash tomorrow, oil and power steering fluid everywhere. As I look at the bay I ask myself and now you, is it possible to use the crossmember and steering rack from the zx. That would resolve the oil pan issue. It looks like the bolt holes are exactly the same width apart every way. Or don't you know either. What are you doing for the suspension? I heard that the s13 coilover kit will work. Is that right from what you know. I guess that's all for now. later

[brandonjustice93J30]

I was taking a moment to update myself on the ongoing turbo projects and seen where 95-J30tt said hopefully soon there would be another sleeper J. I get my new house and garage at the end of June/beginning of July... hopefully....and as soon as I get a couple bonus checks and get another daily driver to go back and forth to work. I'll be starting the J project and reviving the spyder. SO I'll have a full summer/fall/winter/spring ahead of me, starting with the spyder first and then the J. I havent decided to go ahead and drive the J into the ground and wait to do anything til it dies, get the spyder running again first so I can enjoy it for a season and then start the J the next fall or start sooner.

But it's great to see how much teamwork and support has been going on with the existing projects. I'm sure I'll appreciate the resources once I get started. Keep up the good work and documentation. Thanks.

Brandon, are you planning on putting in a VG30DETT.

I really think you shoudl consier swapping a VH45. I know someone in indy that will get rid of a nice VH45 for a good price. I think the VH would be an easier swap than a twin turbo, personally.

[gr8scott72]

I've always thought it would be cool to swap in a KA or SR into the J and pump it up to around 350 whp.

[elwesso]

or put in a VH45 N/A and have 320.....

[gr8scott72]

I think it would take a lot more money to get the VH to 320 whp than either a SR or KA. Maybe I'm wrong.

[elwesso]

didnt realize we were talking about WHP...

Still, VH's can be had for about 1/2 to 1/3 of SR's...

[brandonjustice93J30]

hrrrm..interesting thought. I did at one time see an engine from an M45 once on E-bay and gave me the thought of dropping a VH in there.

I know they had the 4.1 in the J's available overseas...wonder how many mods would be necessary to just drop one in???

I'll have to keep that in mind though once I actually start the project, because given, sound coming from the bov's would be great...but the low grumble of a V8 would be nice too.

[elwesso]

Heres what does it for me.

The VH has the same-ish HP as a stock twin turbo, it weighs less (something like 100lbs), and it can handle a great deal of power down the road... PLus I think a lot of the clearance issues you have with doing a twin turbo wont be an issue for the VH.

I think it would be an easier and more worthy swap.

[ttinfinitiM30]

aaarrhh sorry ppl for the long wait... ive had several things occuping me recently like my pops passing RIP, then laying down a bike on the highway... but now im getting back into action with the ol M. i jus got the grunt of my work on the mazda done and am jus now waiting for a headlight for it. as soon as i get one the m is comming back in full force, first ill be getting that dam power steering rack figured out then from there, engines comming out for the drain pan modifications and some assembly of wat i took apart.. then if all goes well, it'll b going in for its final aproach.

infinitim300x the idea of using the 300's crossmember sounds great. but u called the fact that i dont know. thats where using a front clip in the swap would be great. if the crossmember would bolt up then that would make the job easy. im gonna be using the M's tho cause thats all i gotand ill find a way to make it work. using the crossmember from the 300 might also open the door for suspension upgrade to the 300's. and yes u r correct the s13 suspension has been used by several m owners, but its not just a bolt on theres a bit of moding involved, theres a step by step on the other m30 forum. but im first jus gonna get the engine done first then ill be looking to upgrade the body. hope u try to use the crossmemberin ur project .. if not ill have the solution for u in bout a month or so.till then

[ttinfinitiM30]

ohhh.... wat a shame. i got a j30 rack today, and layed on my back fighting it to slide under the engine/tranns. but as it got close i realized that the dam thing still wont fit around the drivers side turbo. i was really hoping to not have to do any welding to this project. but well i jus may need to. so if any1 has any other ideas please let me know. if no one has an idea then im jus gonna go and buy a rack from some random car that has the dimmentions i need and cut chop and weld to make it fit.

oh and jus so u know the j30 rack for one is too large from end to end (but thats jus tierod swapping) and the steering shaft input is interfering with the turbo....its jus not quite enough

[ca18datsun510]

s13 suspension is bolt on.

[ttinfinitiM30]

ok this is a link of the other site. the only mod was to drill a hole.http://f31club.com/s13_sus.html

[ca18datsun510]

yeah.

his ****s not safe.

if you are using the s13 steering rack, s13 inner/outer tie rods are fine.

if you retain the m rack, use s14 inner/outer tie rods. you will have more thread engagement and it will be much safer.

also, if your car is as low as his you are gonna have **** steering with that angle on your tie rods. use some spl or similiar.

[ttinfinitiM30]

so ur saying the rack from the s13 fits the m?? do u know if it is any wider than the M's rack? i mean the center part of it, not end to end.

dose the s14 rack fit?? maybe

[ca18datsun510]

the s13 and s14 racks are the same. cept for the s13 hicas rack.

they will fit the m30 if you use the s13 or 14 front crossmember. which puts you out of the v6.

m30 rack itself is narrower then the s13/14 rack.

[infiniti m300x]

Do you have the transmission installed with the drive shaft connected to the rearend? Curious, cause I finally dropped the motor in my M last night. Been busy with SPL competitions all summer. The reason I'm asking is cause I would like to know how far the motor is to be away from the firewall. Useing the 300 crossmember isn't going to be cut and dry FYI. It looks as if I need to move the member forward 3 inches, because the top drive side is hitting the brake fluid resevior and lines, and the mounts are that far away from making connection. But I know that won't work cause the suspension parts won't match up. I'm debating on welding some steel to the member and drilling holes for the mounts. But then again I want to make sure the motor is as far back as it can go. I'm seeming to not have problems with the steering column as of yet, however I cant fit the rack in due to the oil pan needing to go back an inch. I feel I have made a major accomplishment, however I know getting the motor in is a very small feat compared to the battle I face. I hope all is going well with your M. When we get these done we'll have to link up @ some point.

[ttinfinitiM30]

ooo....so ur using the 300 crossmember. the point of reference ive been using for the location of my motor has been the engine fan in the fan shroud. sorry dont have it in right now for the firewall measurement but if u try and fit the radiator and fan shroud in then it should give u a good idea where u need to go. i still havent gotten a driveshaft made yet but thats towards the end of my list. its important to have the engine sitting in a good place before u get the driveshaft done. any good driveshaft shop should b able to make u a shaft to fit what u need. maby instead of slapping in blank steel on ur xmember it might be possable to frankenstein the crossmember. cut off the sides where the mounting holes are, from the m's xmember and weld them in place on the 300 member. i dont know if it would work but it might be an idea to look at. but before u start welding anything id try to get teh steering figured out cause u may need to do sumthin crazy to that.what im looking into is removing the stock steering mounts and lowering the rack a few inches. if im lucky then that will be my answer to getting around that turbo.goodluck and keep up the progress
