SS autochrome manifold question.. on installing

[sil820]

im installing the ss autochrome exhaust manifold but i cant get three bolts on becuase there to close to the tubes. how should i go around this? will this cause an exhaust leak??? how should i install this? one more question..what fuel injectors should i order for the RB20det.. i kno there side feed...what impedance do i get.. and so on... i have turbo upgrade...so i was thinkin something 550cc

were those nuts supplied by SS autochrome?

but if they weren't, you could always try to get a smaller head bolt at the store. Try to get those on though, cause it will be an exhaust leak.

not sure on injectors. cant FC Rx7 injectors work? also, what are you gonna use to tune them? (curious)

[sil820]

damn it doesnt look like anything will fit... ill take pix soon.. ss autochrome didnt provide me with any nuts. i will be using an emange setup

yo rb20det injectors are top feed buddy. i just installed some supra mk3 440cc injectors on my rb20det this weekend. easy install and u can get those injectors for cheap. 440cc theoritically for our 6cyl beasts are good up to 400hp.

and yes u need to bolt everything tightley or expect an exhaust leak cuz im running 15psi now already i blown an exhaust manifold gasket on the stock manifold. TIGHTEN EVERYTHING!!

stock series 5 RX7 injectors are 550cc and will bolt right in. No resistors required. But unless you are building bottom end you wont need more than 440cc. I use stock GTR injectors which are 440cc and gtr resistor pack.

Also - how do those SSautochrome manifolds hold up. Super low price, so i was just wondering if they are notorious for cracking and what kind of HP they can flow and how much difference from stock? Did you get the top mount one?? and is it in a 240?? How does it fit? clears hood and steering, etc.??

From what I've heard if you brace the top to the head it won't crack at all. They don't look like they will clear the hood but always do.

Rx-7 injectors are direct bolt in!? I'll remember that when I go get a turbo upgrade. Never heard of a series 5 Rx-7 though.... do you mean 3rd gen?

naw - its one of the versions of FC. I think they were only in Japan. I looked for them forever - but finally got my gtr injectors and like 2 days later there they were on ebay. Oh well, i dont think i'll be needing 550.....not on this one at least.

i hear alot of people knocking on ss autochrome but honestly i have bought there kit and its fine the welds are crappy but other than that know problems i bought the "super" turbo kit they have on ebay and its great so everyone that is talking about them is mainly just saying what they here iam sure some people that have had problems but there are some who do and some who dont but i went ahead and tried it just to take the chance and i was happy with it and yes its a good idea to brace the collecter a lil better but that is with any top mount
