Installing Tomei Procams, Gears, Lifters, Shims And Garrett Turbo,

[Cartman]

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..

What was the problem???

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???

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.

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

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

hrmmm. very informative.. i spose any confidant head guy could set it up with 26 gear in it.. but if you are going to so much trouble we may aswell just use a 26 head........

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.

Hmmm 600-700 really isn't that bad of a price.

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.

ok cool. just off the top of your head, whats the process involved in the conversion using oem nissan bits?

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

[FineLine]

Best give them a call and talk to them yourself.

07 32086533. John most likely will not be there (gone fishin) Just ask for will.

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.
