cast manifold worth a look for na-t

just seen this on supraforums might be a cheap alternative to the xs power one and should be by the look of it less clearance issues

Why oh why do these people make such a small wastegate hole periphery? It's asking for a gasket blow out, they should have made the land area much wider, and three bolt. Hopefully the material spec will help negate any distortion. I would love to see one in the flesh. It sure is looking like it will be a lot more reliable than the Chinese tubular stuff. I wonder if there are any issues on a RHD car?

Looks good may be tempted to go na-t now

i think it works out around £250 maybe less so if it is decent it might be worth the chance it should help with clearence issues though and i know you cant tell on the pics but it also looks like it shouldnt have dizzy issues either

If I was doing an NA-T I would look at something like that and possibly weld/seal up the wastegate port and look at a small internally gated turbo

wez that is a very good idea that would deffo keep it very simple

Yea, a nice GT3071R would be perfect for that - super spool as well.

It's designed for a vvti 2jz-ge, would it still work?

Doesn't look like it would fit a non-VVTi with a distributor.

I dunno i think you might just get away with it tbh. It does sit quite low and central to the head.

Be worth a try, either that or find yourself a VVTI GE

Also depends if the bolt pattern is the same of the VVTi

True!

Interesting to find out as the vvti ge's have a very different style of manifold compared to non.

At first I thought that was ridiculous, but actually a vvti NA-T conversion would have some pros. The wiring would probably be a PITA, but replacement engines would be cheap and plentiful, and it would most likely make for a very responsive setup with decent economy. Hmmm...

I'd still rather a good tubular manifold though, someone pointed out not so long ago how crap log manifolds sound compared to tubular, quite a difference.
