i tried searching but couldnt find any info...has anyone ever tried out the revhard t4 manifold for 4g63? i know rechard is pretty good as far as honda parts go but ive never really heard of anyone running their manifold on a dsm..

up..anyone?...im looking for something other then the newer t4 manifold out thats looks like a big block of metal....also considering SFP but came across this..

url?

heres a link...its close to the bottom of the page...the picture is coming up as a red X but i emailed revhard to see whats up with it

http://www.revhard.com/parts.html

I've heard that revhard products arn't very good, their exhaust manifolds don't withstand heat very well. But I do know that South Florida Performance makes some real quality products. Here's a link:

I still don't understand why u don't go with the HKS exhaust mani, just cause it looks like a POS doesn't mean that it is.

i never said anything about the hks manifold...im talking about the newer released t4 manifold that i dont like....if you can find an hks for a reasonable price or even find one at all, send it my way.

spf are an on/off product quality from what ive heard...sometimes you get a beautiful manifold...other times it looks and fits bad..i dont really want to go through sending manifolds back and forth till i get one that is right.

well i dont think you have any other options

I have had at one point or another all three manifolds, SFP, Revhard and HKS. The best out of the bunch by FAR is the HKS. Next on the list is the Revhard (cast iron won't crack) in a nice package (clean turbo placement). I think the SFP ties with the Revhard...

The HKS is SOOO great because it is a tangical divided runner that uses split exhaust pulses (4+1 and 2+3) and the placement of the wastegate passage. TRY and find another manifod (even a tubular) for under $1K that has the 4+1 and 2+3 design, you can't find them for under $1K...and the ones you can have will have a shitty wastegate placement. If ultimate power (+750hp) is your goal, there is no other alternative to the HKS. If you want an HKS I have access to 3 of them. I can get one to your doorstep for $2250, and it'll take 3 weeks min.

Wait for another couple months and I will have access some HKS recasts (there was no patent on the HKS manifold) for $1200...recast in STAINLESS STEEL!!! Better than the original HKS. This is the manifold I will be running on my car when they are done.

2250..ouch...my goal is around 500-550 wheel hp, so i think maybe one of the other above mentioned would better suit my budget and needs...1200 isnt too bad at all for the hks recasts in SS that you are talking about...maybe ill go with a revhard or SFP for now and once the recasts come out maybe invest in one...thanx for the input

I hope you've read some of the performance upgrade recipes because judging by your profile you're a long long long ways off from needing a new manifold, if ever.

umm...i just sold my 650rwhp supra that i built from the bottom up. granted i dont have alot of experience with dsm's having only owned one 95 gst in the past but all cars are basically the same and i dont need people making assumtions about what i need for my car.

Yeah, you're right. Naturally aspirated and turbocharged cars are pretty much the same. I'm not making assumptions, I was just trying to make sure you had looked into exhaust manifolds and at what point people actually upgrade. Hmm...10's?

what the #### are you talking about? my old 94 supra, turbo...my old 95 eclipse, turbo...my 92 laser i have now, turbo...nothing n/a about any of those cars

and yeah ive looked at what people are running, only thing is the majority of people dont go with a t4 manifold and turbo setup, especially the revhard manifold that i am asking about...didnt know i had to get critized on asking a question about if anyone has tried out a revhard manifold by someone that obviously has no knowlageable input on the subject...

Thus my reply. Enjoy w/ your fully built car. Please post dyno graphs when all is done as well as the time slip of the 9 or 10 sec. pass in your beast.

ohh yeah your totally correct...all cars are build on totally opposite platforms...among the cars ive had last time i checked they've all had pistions, rods, a crank, fuel injectors, intake and exhaust manifolds, ect....and all run on the same principals....whats so different about having a turbo stuck on the exhaust pushing more air into the engine, doesnt take a rocket scientist to figure stuff out. but thats not even the point here, i still wondering why i am even bothing responding to someone like yourself

dont come in and hate on other people's threads just cause you think your a badass...its not kool.

I didn't "hate," I simply made a polite reply to be sure that you had looked into it, to which you made an assanine comment that i was compelled to keep replying to. Again, Good luck. Be sure to treat your I4 turbo motor with the same principles as you would treat a V8. That'll make it real fast.

yo gritsak, take it easy mo!! I respect ur question and i'm just trying to help out. Did u do research on anyother turbo's than just a T4, i'm sure u have. Cause i was also gonna do a T4 setup but it was gonna be too much of a bioch. Plus ur gonna need NO2 to get that turbo spooling. Unless of course this is gonna be a pure drag car.

Supra heh, not too shabby.

you dont always need n20 to spool a turbo, maybe he did his research and went with a t3/t4 dual ball bearing set up like I did, with proper tuning you should see almost instant boost I believe it was 2000 RPM for close to full boost (15-17) cant remeber which. anyways I am curious about which manifold you are going to go with because I am in the same boat, looked at quite a few cast ones and also the florida shops but he told me 18 months to get one.

You dont need a full T4 setup on dsm's to fun 500 hp? I know people running t3/t4 setups making 500+ whp. so why do you need this setup again?

im going with a full t4 setup so that i dont have to upgrade my manifold in the future...i am used to full boost by 4500-5000 like i had with my supra..lag is overrated IMO and i dont mind having a manily top end power range.

i didnt intend this thread to end up bickering between people...all i wanted to know was if anyone has any experience or opinions on the revhard t4 manifold....what i do with my car and my setup should be my choice...i dont need people telling me what i should and shouldnt do, i know enough about cars and turbo setups to know what my needs are so unless you have some input on the actual question i asked please take your comments to another thread...thanx

rev hard is run by miles bautista(he uses the same components on his own car), the maniflods are either cast, or tubular. i had a rev hard kit on my b16a civic si. the fit to finish was very nice, with the cast manifold. it never cracked.

my opinion rev hard makes a good kit. they were one of the firsts in the early 90's to start producing kits for imports.

yeah ive heard pretty decent things about their kits for hondas..i was even considering getting one for my gsr....i havent heard an awful lot about them with the dsm crowd though (as far as their manifold) i think just recently more people are starting to consider switching from mitsu and mitsu/hyrid turbos to go for the t3/t4 and straight t4 setups....seems like theres alot more variety this way and not to mention alot more and cheap turbos available that can produce big HP

i plan my next turbo to be a mitsu/hybrid, but i have been considering the full garret kit from agp turbo.

how much different is the full T4 from say the GT series turbos?

I completly agree with the lag issue!

Secondly, Welcome to the wonderful world od DSM's. Most talk of what they do not know. And will argue about it as well.

I cannot remember whom it was made by, but there is another cast HKS knock off out there, that might suit your needs.
