It will give gains, but you wont hit 600 It will give gains but it wont get you to 600 imo. You will also sacrifice low down and you will be adding extra volume if you port match it, more so if you port the plenum runners depending and how its done I think the only time youre going to see about 100hp gains is if the car is making well over 1k kw I do have a spare set that I was going to test with, but i dont actually think there is anything worth getting going larger. I did a fair few S14/S15 and the standard TB is fairly small, I went to 60 and in some cases 64mm which is significant over the stock unit. You can also get some weird ratio changes. I think 20kw will be a stretch on a roller dyno. If I had it apart I might mill the shafts a little and not expect much, I think the stock size is still pretty good for a street/track car even with larger capacity. I might change diameter it if its a drag only car

old solution was to add a spacer

I have also noticed nozzles getting clogged over time. It seems that the brass is reacting and corroding with meth/alcohol. It doesnt seem to be as much of a problem with just water, unless you are using an alloy water reservoir I have considered mixing a lube in with the meth or using glycerin with the water before mixing them together.

If I was given N1 manifolds I would use them, but I would not pay for them since the difference is so minor and can be done with about 30 mins and a die grinder. If you go larger in I.D generally you will loose port speed and incur lag. Sometimes with no appreciable top end gain. You can make up some of it with collector design but with low mounts you are limited.

look like -7 possible that at some point one broke and was replaced or they were from different batches which is perfectly fine.

I would be careful selling this as a hks bov, according to this it is probably a copy: http://my.is/forums/f114/compared-fake-hks-bov-real-hks-bov-new-type-4-fakes-434959/

so how do you get the extra 30% off? Currently its 10% off what am I missing?

3 speed!?6 Ahh os 1st to 3rd, stock 4th and 5th.

How come you chose to run them straight off of your plenum instead of run the plenum size you wanted and have the heat exchanger seperate?

No doubt the twin 6258 spools well for an 800 hp set up, but if youre comparing it to the dog shit 100% stock car that is lazy below 4k rpm its sort of unfair. An rb26 that has stock turbos can build 5psi no prob at 2k rpm when basic mods are done. Mine would toot around in 5th grear with 255/35/18's at 60kph. 6258 are atleast 100hp each more and with runners that are not optimal for low power/rpm/boost tootleing around. No way would it have factory type drivability which is of concern for most who like in a major metro city in australia which does not have the open type roads America has.

Doubt it will be amazing. The s4 rx7 had this, made no real difference on stock to to4s internals.

4.363 2 way $780 possibly tomei, maybe kaaz too (should have under 4k klm) sold
