Is Jam manifold still for sale?

You can port the stock one out quite a bit which helps. The JAM manifolds are good but you have to remember they are a 20 year old manifold now.

Ok thanks for your time and information

I m confused so i will try to find a Jam unit because I want to look stock user bonnet....i believe it is stronger and flows much better than stock with stock boost level....

They don't crack easily. But they do crack, any manifold is prone to cracking. 

Thanks for all the useful info

So no one suggest Jam manifold because they crack easily like stock

The one I have has two small cracks which need to be repaired. The cracks don't affect the performance, but after so many heat cycles the crack may spread and ruin the manifold. 

Can you send me some pics please.I want to inspect the cracks because I want to buy one and I want to know if they are repairable.

Thanks a lot

Yes ive got one that was heavily cracked. repairing them is a time consuming job as the cracks all need ground out completely, then it needs preheated, then welded with high nickel content filler wire or rod. then you need to let it cool down slowly then grind anything else back  and repeat each time.

I think ive got pictures somewhere, but just had a quick look but not quite sure where they are. however a cracked jam manifold looks just like a normal cracked ct9 manifold i guess.

So it's waste of time and money....what boost pressure do you run?maybe they hold easily the stock boost!

Thanks for reply Bean

They still crack at the collector like the original though. 

Only at the collector or they crack outside?does the cracked collector affect?

This is my one t hey don't crack like oem manifold's as the restriction is gone so there's less heat build up  in terms of price you'll  be looking at £300++++ if you can find  some sold previously on the jap auctions  for mental money 

Thanks for reply Matty gt....so they are better than stock ones because they don't have restrictions.Pobably you get better performance with one of them.

That's why I'm trying to find a jam manifold

Yes it does....no matter just drop them on

Are jam manifold reliable?Or the they crack like stock ones?

And how much is a normal price for o e of them?

Thanks

If it's completely stock it will restrict boost in 1st and 2nd gear untill you bypass the hi low function.

Cheers nick 

It is nothing to do with restriction....it happens to all gears

Thanks

As title....i am a stock ep91 glanza owner

When I push the throttle it boost fine(three lights on tacho an a lot of power and torgue) utlil 5000 5500 rpm the boost lows down (two lights on tacho and less power and torgue)

Any suggestions

5th gear is long enough for 150+ mph lol

I know but I want to reduce highway traveling rpm.....c 56 box 5th ratio is 0.815:1 I want to swap 5th gears from mr2 spyder or celica gt 0.725:1 ratio but I don't know if the gears are suitable!

???

Are the internals of the boxes interchangeable between them?

Also is there any 5th gear with longer final suitable for these gboxes?
