i can get a almost new t-78 kit, everything but the intercooler for 3 g's. some1 told me msrp on that is 3900. does that sound right guys?

i was only looking for about 350 to 450 hp. is it not worth it to buy such a big turbo thats gonna take longer to spool? maybe somtime in the future if i fall into some more money i would go for more hp, but i dont think its gonna be for a while.

arent t-78's used for like 700 or 800 hp setups?

what rpm does the t-78 start to spool hard?

i would appreciate your opinions, thanx

t78 is a lot.

you need a good street port (at least) full exaust, good fuel set up, and of course without mention a stand alone ecu.

if you are only looking for 350-400 rwhp its possible doing this w/ stock turbos. if you are going to work on your car a lot, have extra cash, and have a higher goal then 350-400rwhp then go for the t78.

do a search and you will find a lot of info on this turbo. also look in the sigle turbo section.

all that is covered, i have been plannig for a new motor and all that for a long time.
either way, i want a better turbo or turbos than stock, ive already decided this.. all i need to know is if that turbo is unecessarily big for 350 to 400 hp , maybe 450.

L8NightDrifter

this is urgent because i have a chance to buy this b4 its put up for sale..i have only a couple days to decide...

btw is that even a good deal? 3 g's? is msrp 3900?

Enconsiderate

i do think that is way overkill for 350-400 rwhp. if your going to start modding your car and eventually go over that then yay go for it. also be aware that to get the most out of the t78 you will have to start moving out of pump gas.

oh i forgot to mention you need a IC too.

personaly I would not go for that set up to acheive 350-400 rwhp. i would spend my cash other ways to achieve that goal. Like I said, it is achievable on stock twins. (at least the 350 rwhp)

in the end its your cash, good luck.

Well, as everyone has stated. You need an IC, fuel system, ECU, porting, etc... for a T-78. All that is a pretty penny in itself. As for price of the kit, I know of two places that are cheaper than 3900.00:

First one is the Rx-7 store. I think it retails for like 3399.00 + shipping. Not to bad though. Just call first to make sure they have the parts in stock first. If you order from this store, you won't get "janked."

The Second one is RevHighOnline. The place is cheaper here but I'm not to familar with the quality of the site or know anyone who has used this. The kit in this site is for like 3240.00 + shipping. Anyways, as u look through this, all the Greddy products are cheaper than all other sites. Everything else is more expensive.

You also need more money for everything else. Just in case u didn't know.

i really need to upgrade gas to run t-78? dam i dont think i want it..
like i said, ive alredy decided i dont want to stick with the stock twins, what kind of turbo set ups do you think i should look into for the amount of hp i want? i think i might want to get one big enuf for 450 to 500 hp incase i want to go faster when i have more money..

lol and i know i need a ic thanx

L8NightDrifter

thanx a lot man. if msrp is only around 33 or 34 than i definately dont want it, i thought if i was getting like a hellava deal, then i would want it..

L8NightDrifter

wth, why has my thread been moved? what does that mean?

teeter

buy my single turbo kit for a quick spooling 400 hp capable turbo...for only 2k and use the other 1k for somekind of other cool parts.

see the forsale parts section. t04s

your gonna have to upgrade your fuel system for almost anything over 300 rwhp. you should learn a lot more about these cars before you throw yourself into a single turbo. stick with a near stock car for now, and do the reliability mods. do things gradually. this way you dont total your car the first time you slam on the gas in a single turbo rx7 like 50 percent of the new to single turbo people do.

rx7f4n4tic

for that kind of power get a gt35/40 or a gt35r, again any way you go you WILL need fuel/exhaust/intake/IC/standalone. Porting helps a bunch too ;p

Enconsiderate

if you want something that spools quick and has your target hp#'s I say get the apexi rx6. i think that would be perfect in your case.

oh and when i mentioned the different gas I didn't mean you could not use the t78 with pump. what i was saying is to turn up the boost over approx 14-15psi you will have to use higher octane gas, hence to benefit from the t78 you need better gas.

thread is getting moved since this is a single turbo ques. its going to the single turbo sec.

The msrp on the t-78 turbo kit is $4500 but these place like rx7store and high rev sell them below msrp.The other members are right you have to upgrade your injectors if you want to go single turbo and boost more.

L8NightDrifter

i appreciate the concern buddy but, ive already driven it stock for quite some time. and i have spent a long time learning exactly what im getting into. im still kinda nubish but im well aware of how much money i have to spend and how problematic my car is. and im well aware that i have to upgrade my fuel system and reliability mods. ive been saving up for years and plan to waste quite a bit of money on my car this year. and ive owned a modified gsxr750 and driven a few very fast cars, im not gonna total my freeking car (knock on wood)

the ppl that posted after your post is exactly the help i was looking for. i dont know how many times i said that ive already decided to upgrade from the stock twins, plz dont post if your not gonna try to answer my questions

oh and for every1 else saying to port my motor, ive already spoken with pettit about doing the labor for me, buliding the motor as well as installing the other things and tuning.. so ive already decided to port my motor but i only chose pettit in FL because i heard they do good work, if any1 has heard anything bad about pettit plz let me know. i havent decided for sure to bring my car there, they are the only shop ive consulted with about my car. and if any1 knows of a shop that is more reputable than pettit plz let me know also. i know of all the shops, or most of them i just dont know what their reputations are

Black97VR4

KDR is good. RX-7 Store is good. Gotham Racing is good. Lots of places are great shops. Personally I would pick one fairly close to you.

And open your mind up to several different choices in turbos. The Greddy kits are really nice but the newer kits like the R85 and GT40R might just be the way to go now as they are becoming more and more popular and people are starting to get good numbers out them.

L8NightDrifter

lol i would want to pick a shop close to me, but since all shops are many states away i just want to pick the most reputable shop to do the original work, since i would prolly have some local shops without too much rotory experience do minor stuff when i run into some prblems i live in MN btw so if any1 knows a a shop with a great reputation near me that i might have overlooked, then plz post

If you want only 350-400rwhp then you could go with the t-78 and run at 14-15psi, 15 should take you over 400 though some what. I have a stock motor with a t-78 but mine has a upgraded wheel so it spools up a lil faster than a normal t-78. I get full boost at 4300-4500rpm. If your going to run higher boost you need a street port though. Its a damn good turbo and it pulls like hell if lag doesn't really bother you, which shouldn't because it is so overrated then go with the t-78 later on if you feel like it you could just turn up the boost have it retuned and get more than 400. Most i've ever seen out of a t-78 was 503rwhp at 19psi on a large port with race gas, in theory i think the t-78 could flow 600+. Its a great turbo buy it but if you want faster spolling go with a hks t04e or do bnr upgrades to the stock twins.

L8NightDrifter

i was planning on getting a street port. i have over 75,000 miles on my stock daily driven fd so im due for a rebuild. how much does it cost to upgrade the wheel dealy? and where can i find some info about that? like who does it?

i only say i want 350 to 400 hp kuzz i hear you run into many more probles more frequently when you go higher. im gonna get all the fuel mods and crap so i guess i could just get it tuned for a higher setting too and just turn up the boost if i wanted to go fast, but the only reason i dont want to is FEAR. i cant afford to deal with a blown motor i dont know how to fix anything myself. i bought a step by step video on overhauling a 13b, but i dont trust my work lol. realistically i prolly wont even go over 350hp kuzz im so scared, but there are a lot of friends of mine and local guys that have 500+hp street hondas, and i want to be able to atleast keep up with them

importrx7

**** them and there hondas, you're in a rx-7, a rare bad *** car, no matter what you do to a civic its always going to be a civic and there motor at 500 isn't reliable for ****. There are RICE, and 7's aren't

L8NightDrifter

lolololz!!!! i never meet such a honda hater, it woulda been better if you answered my questions about the reliability of going over 300 hp...

and btw ive seen a reliable 550 hp turbo type r, races it all the dam time, daily drives it, took it to cali and back, put over 20,000 hard driven miles on it with no probs yet, ran a 10.1 full interior no rollcage. its in a hb btw. and this guy owned a maxed out fc for years b4 building his hb, he said he wont ever sell the fc, but the fc will never hang with the hb.

ive owned many hondas for daily drivers, they are so reliable, especially the sohc's i drove my crx on redline for years and tried to kill it, it was still pulling hard when i threw it out kuzz of the rust with almost 200,000 miles.

i personally cant do without a RWD car, i just think fwd really sucks, i hate when the front wheels spin, its like pointless and when they are fast, they put those big nasty slicks on front eeww..and its just not fun to break traction in a fwd.

but you gotta admit, you dont even need a lot of hp in a 2000 lb car, it just goes. and hondas like rotories have the best hp per litre ratios, its just that they last longer

SideWindeRx7

use water injection and run a conservitive timing map ... you wont have to run 100+ oct gas all the time if you want to boost 20+

L8NightDrifter

?? im not sure what this means, i was never planning on moving out of pump gas. i beleive the question was "is it true that going over 350 hp will run into problems much more frequently and have a good chance of blowing my motor?"

and btw that 10.1 hb runs on 92 octane

importrx7

Anytime you mod a car you increased the chances of something breaking, once you start to go over 400 you really kill what reliablity you had left. You could get lucky but once you start modding **** can just start to go wrong left and right.

L8NightDrifter

thanx for all the help, after seeing what some of the heavily modded fd's are going for on the forum, ive decided to take my money and try to buy one that is already fast, then ill prolly end up doing some minor work on my stocker and selling it.. of course thats only if another good deal comes a long soon, otherwise my patients will prolly get the better of me and ill spend the money on my stocker
