having attempted to use this "tomei solid lifter conversion" i highly dont reccomend it.. i know of some brand new tomei buckets and type B valve springs if someone else wants to have a go..

extremely unhappy with the fact that they required such large lashcap style shims 5-6mm+, was easier and cheaper to have JHH convert the hydrolic lifters to solid.

that was the case in the head we went to set it up on anyway.

Very frustrating to read these threads and not get the ending. Did the Tomei man get his engine to run properly, make decent power?

I take it you would be recommending Poncams as a simpler job with good power for the street?

Really depends on the setup and what your aiming for. if you want to do the solid lifter conversion while rebuilding the motor i highly reccomend getting JHH to do it for you great workmanship and excellant porting.

however i wouldnt reccomend the solid lifter conversion if you arent goin to take advantage of having it done.

Who is JHH???

John Hill engineering here in Brisbane.

I am with cartman, the tomei conversion is a donkey f**k. John did my conversion and head work and couldnt be happier.

my understanding is when going to a solid lifter from a hydraulic is that you will require new Valve's as they are an extra 5 mm longer to suit a solid conversion and take up the extra spacing or shim thickness required.

I went through all this when i installed hks 256 deg in and 264 deg ex cams with upgraded valve springs.

My lifters bleed out after a while when the engine is not running from the extra tension in the springs. I explained this to my engine builder who at the time has not done any upgrade's on a 25 b4. I was going to convert to solids to try and illiminate the proble but then engine was together and thats when i found out that you require different lenth valves to suit

What was the cost for the conversion FineLine??? Also any idea of freight costs from Tassie to Bribane??

Dont hold a gun to my head because i really cant recall the pricing but i believe it was somewhere around the 6/700 dollar range for the conversion, My bill was a fair bit more than that because i did some o/s valves, heavier springs and some major port work to boot.

It worked out far less expensive than going to a 26 head because i already had a greddy plenum and himount manifold etc to suit the 25.

Plus throw in the cost of buying a 26 head and you soon realise its very good value to convert the 25 head to solids.

Sounds like you have done what im planning on. Was he good to deal with? Any chance I could have a spec list of your setup and how much it can flow? Am now looking at bigger cams but not sure whats "to big". It will be on a 25/30 with T51r and a 8200 - 8500 rev limit.

both john & will @ jhh are both champs. john is semi retired now i believe so its mainly will and another bloke there.

will is just like john though, he recently did a big head for me and it came out spot on how i wanted it, perfect

noels (fineline) only got baby poncams in his head, he also runs a 35r .82rear, i'd be looking at 260-280deg 10.5+ lift for ur setup, but depends on how much coin u want to throw at it. the head i got done has 1mm valves both sides, dual springs, ti retainers, bronze gudes, big port work, intake 270 10.8 exhaust 280 10.8. its on a 26/30 with a t51r kai, rev limit will be where it stops making power. no numbers yet as its waiting engine mounts to go back in

I see what you mean Cartman. Just by sitting the type B spring and solid lifter in the head its easy to see that its going to need a fairly decent sized shim in there. Might just put them aside for another build that may come along lol.

    • Ducan , yeah sure mate , the unit is https://www.carlinkit.com/ambient TBox Ambient -  plugs straight into the USB C and it runs as a android  unit and you can link your phone to it via Bluetooth , but it only allows for one phone at a time. you can download and apk files you want and load it on there , I downloaded a basic maps apk (OsmAnd+ — Maps & GPS Offline) so I can run navigation without data usage , its not as good at google or wazes but it works fine for what I need. I can put up screen shots if you like. Cheers Pac   
    • Hey Team , just got the Fujitsubo unit installed , not a big db difference but it does sound better across the rpm range , I have the front pipe on order I'll post a video with sounds when that has also been installed.
    • The gearbox in my R32 GTS4 (now with RB25DET) has just over 300k on it . Life includes some track time. Has had one change of oil in its lifetime. I rev match on down changes. I don't have any problems with synchros or gear crunching.
    • Currently advertised with some A4 flyers up at work for $30k ono Will detail it next week, and get some good picks for carsales, then put the cover back on and put it back on the tender until someone comes to look at it No real hurry to sell, in saying this I would like it gone with in 6 months as I am retiring in May 25 and lose the ability to store the car undercover in a secured site, plus as we are moving out of Sydney the potential buyers market will be more limited https://www.sau.com.au/forums/topic/485907-2002-vx-ss-commodore-30000-ono/
