The reason I made this thread was to try to get some useful info as all of the older threads only have tidbits here and there, while I do appreciate banter and suggestions of shoe horning V8s into cars, for the sake of someone trying to make a decision on this topic - is the general consensus that you really don't need to convert to solid lifters unless you're chasing wild above average power and rpms?

options - 

Stick with hydro lifters possibly make 450kw at 7500rpms assuming all the right supporting mods for that goal

Spend the $600-800 for the Solid lifters and find out how hard it is to set the clearances and what else needs replacing around them

Neo head - possibly will cost more depending on the head prices at the time

Throw away RB or buy a BMW 😆

There's a lot of the solid kits getting around from different manufacturers so someone must be doing the conversion

Haha that is a wild idea, how about a banged up R33 and a case of beer? Mates rates? 😁

No more 90s JDMs for me, just want 4 door cars that won't attract cops.

Wouldn't mind a Hako or a 240Z all motor but modernised (big comp, big cams, ABS, DBW, dis dat).

You can definitely do 450kW on the RB25 non-NEO head, plenty have.

The $600 to $800 conversion will end up costing you much more I suspect, I believe you will require machining.

NEO head has the lowest barrier to entry.

 

My 2c?  buy a BMW 😆

as hydro lifters/ head will do 450kw no probs - went through many race engines at that power and 7.5 - 8 K rpm and the head was never the problem  especially if a street car you not going to push it hard enough consistently enough either

solid lifter conversion is big $$ not $600 - $800, do this and that and put em in

I know someone doing nearly 800kw on poncams 😉  well a few tbh

The way I see it is if people are happy to spend 10's of thousands of dollars on a build, a couple of thousand to get it engineered is good insurance 

The funny part is, an engineer's cert still doesn't actually make the car legal. Interesting part on that :/

IE, even some cars from the factory are defectable as they sit in the showroom. So even stock doesn't mean legal. :)

btw... here's a fun quote I got back in the day (using a NEO head and going shimless):

a bit different initial requirement

 

 

Just had a chance to have a read of this, exactly the type of info I was after thanks for that! Amazing that thread never showed up in search

Yeah I'm definitely getting swayed away from the solid conversion, plenty of people getting impressive results without it

And the rules change with time ...but speaking to the premise you raise here, some of us old farts will remember seeing every police motorbike with a rubber rear mudflap extension, fitted to the end of the rear mudguard. This was due to an ADR that required the rear mudguard to extend lower than the rear axle (iirc 15 degrees lower as measured at the axle center line)...it was changed in '89 updates, but basically before that date, any road going motorbike was technically 'illegal' (unroadworthy) ...the whole area is a real prickly pear... 😃

Things change over time but all that matters though is that the vehicle is compliant with the rules that were in place for the year when it was constructed. 

Go back far enough, cars didn't have seatbelts or catalytic converters. You can still legally drive them without a seatbelt or cat fitted.

It's not like vehicles need to be updated every year to match the updated ADR's to stay road legal.

I'd say the most common scenario is the car's build has 2 stages, all work that can be engineered is done first. The car is passed then the second round of mods start, all the ones that can't be engineered lol.

It still doesn't matter to the eye of the law. It's all those annoying grey areas. Engineer the car under a specific area, but that same thing is still illegal elsewhere. Hence, still not legal.

We are talking about different things, all I'm saying is there are plenty of people out there that don't stop modifying their car after it has been engineered.

Poncam the world

If it's for a SR20, make sure it's not the American Poncams, might as well call them Poocams. Had a set in a friend's car, all scuffed up after a few track days. Like the metallurgy Tomei USA used is junk. Went back to JDM OG Tomei Poncams, no issues till now.

 

Tomei USA is not the real OG Tomei.

 

Random rant over, fk the US of A, bunch of c u n t s.

It's unfortunate what Tomei USA has done to Tomei's name in general. I'm very weary of ordering parts from them now. I only order direct from a Japanse source (e.g Nengun). At least their logos are different, so you end up knowing what you have.

I have personally seen a Tomei USA RB26 cam that didn't even fit the head. Kind of nuts to me that it was even possible for that to happen but such is life.

There's two UP Garages in the US. One is a US branch of the Japanese company which sells things they brought over at tremendous markup. The other is University Place Garage/Fairlady Motors which is a shop best known for putting VCAM in RBs and trying to convince people to stop putting in 800hp of turbo on a 2.5L motor.

I guess that's what happens when someone can't convert metric to freedom units to machine something. 😛

Remember when those donkeys kept using freedom units and smashed that satellite to bits on the moon?

NASA has their brain switched on and uses the metric system.

    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
