Heavy Throttle Turbo Kit

[240SXer]

I'm curious if the Heavy Throttle Stage 1 turbo kit for the SR20DET is any good. I was thinking that maybe i'd want to go with a larger turbo, but all I'll ever want (or at least for a while) is to be able to run in the 12s on Street tires. I'm fairly sure I could do that with around 320whp. But anyway, the kit is $2,325 and it comes with all this stuff:

HT Custom Turbo Upgrade Kit Stage I:

Forced Performance Big28 turboJWT custom tuned ECUDENSO 550cc injectorsZ32 MAF w/ filter and install kit

------------------------This turbo upgrade will provide 320 RWHP with appropriate mods. Brand-name components ensure reliability and quality. Complete bolt-on kit including everything necessary to install on the stock manifold. Required upgrades include FMIC, high-flow exhaust and fuel pump. Recommended upgrades include metal head gasket, Trust turbo Extension, higher pressure BOV and upgraded radiator. Please call for availability, some components may be on backorder. ------------------------

Opinions?

What else would be needed? I'm sure a fuel pressure regulator, maybe a fuel computer? Or would the JWT ecu be able to work good with 550cc?

Seems like a lot of money for only 320hp...get a big 16 or even 20g for 500-600, an safc and injectors, and the ebay manifold...wouldn't cost much at all to get the manifold altered at any machine shop...then you don't have a ecu tuned only for your current setup, and you won't have to keep getting it changed...and if you go with the 20g then you'll get your 320hp at low boost and if you want to upgrade its good until 400hp+...

i don't know of anyone that makes a 16G for the Sr motors, you're in DSM world, lol.

that setup seems a bit overpriced, but not too bad. i know for a fact that it will make the power they advertise as i have a friend that pieced together the same basic setup and made 317rwhp and 324tq or something like that.

[240SXer]

At what boost? I want to put down as much as I can on pump gas (91)

[Tai Mai Shu]

BIG28 sucks!

Yeah i didn't know if anyone used the 16g on a sr...but all the same there's no reason they couldn't...the 20g isn't made for sr's either, just so happens there's a manifold to fit...the DSMers got good turbo's man, if it works good on a 2.0l 4g63 it should work just as good or better on a 2.0l SR20...why re-invent the wheel?

Don't see how the big28 is worth the money IMO...

Just get forced performance to make you a big 28 for $800 like they make them for all the DSM guys. You just send 'em you T25 and poof, you have a big28 that bolts on, no custom manifold required. C'mon the Fp Big28 is a great turbo. I have a friend with it on his 2G DSM and it's pretty much nasty. I'd certainly take a big28 over a 16G. And the 20G is pretty over-rated. It doesn't really have a very good turbine on it.

Then, get an AFC, 550's, a MAF, and be done. That way he can upgrade later on if he wants, and not be stuck with a manifold that only works with Mitsu style turbos. Not to mention the fact that he'd have to get a custom O2 pipe if he had a mitsu turbo, everyone neglected to say that.

you can get just the BigT28 turbo from HT for about the same price as FP. And they give you a core charge too. This is the way that I am going because i still want to utilize the quick spool up time as I will still be daily driving. I have heard stories of up to 350+ with them, but not actually seen it yet... we shall find out soon enough.

[ride4lame]

i would say peice your turbo upgrade together, you will fall into deals on things, that always happens. and also the ecu re-tune has to be redone anytime you change things...i would find a turbo, get either an safc or power fc and go from there.

You don't think the Big28 is a little over priced? It's cutting close to Gt25r prices and we all know which is the better of those two... Don't forget to add the not included $100 porting price...that's $900 total (while it's on sale). A GT25r from cheapturbos.com costs $1089...still needs an actuator though.

not to mention cutting the motor mount, and new piping setup for the hotpipe/intake pipe.... and the spoolup isn't too impressive IMO. i've ridden in a friend's GT25R equipped SR and it still felt laggy. given his car makes more power than i ever will, but for something that retains excellent spoolup and can make right at what i want power wise the Big 28 is perfect.

[Dori Dori]

Where did you hear that you had to cut up the motor mount?

I don't disagree that the big t28 is a good turbo...no doubt. But the price is a little steep. I think with the introduction of the Gt turbos, they should drop that bad boys price down about another $100. Just my opinion.

[Tai Mai Shu]

Lets put this in perspective....GT25R great if your tring to reach 350-400 even 450 with cams and the .86arWant only 300-350? get a S15bb and some cams...no biggyFP Big28 sucks I have been around enough to figure this much out....*new info*if you can ring up the cash for cams and the "disco potatoe" its not sappose to be half bad as by Secret Services, It would be interesting to see what it could do in the hands of a caplable tuner....

[240SXer]

I just want whatever power will be required for consistant 12s on street tires. I'd assume that would be in the 300-350whp range. Maybe more, but i'd doubt it. S15bb is a good turbo, I thought that was pretty much the same as a Big 28 though, Phase2 has S15bbs for like $900. Sounds like about the same price as the big28. I want a turbo that will be good for street. If I were to just get a Big28/S15bb, what's the highest boost I can run on my stock injectors? Will that boost give me more power than I have at my current max boost with the t25?

[TruboostPerformance]

I would say piece it together too, but only if you want to spend time on it, but you do save cash, I did my T3/T4 upgrade for 650.00 but I did already have a manifold that I just custom fabbed to except a T3 flange. Other than that I am runnin stock injectors and mafs so far they are hanging, but a good idea is to upgrade injectors and mafs too.

[Tai Mai Shu]

Yeah, dont expect to dip into the 12's without injectors and MAF. You would be better off with an S15bb its alot better just dont get used ones...Rember FP Big 28 is just a rebuilt T25....

[GTS4-R]

T3/T4....enjuku makes a kit....with a header and extrenal wastegate for 2799.....or CTC Motorsports...3000 with header

[GTS4-R]

ps./....over 500 HP pontenial

[solaris22]

500hp on a t3/t4? huh?

[GTS4-R]

http://www.enjukuracing.com ...... Ken is making 544HP on the t3/t4 kit

[solaris22]

you mean T3/T04E

[GraySilvia]

Actually, FYI, they had to put a slightly larger turbo on their race car to make that much hp.

Go look at the website..... they are still running the T3/T04E and made 544RWHP....I actually have the next enjuku turbo kit coming to me.... just waitin on Hotshot for the header....

[EnvyMy240]

where can u find 16-20g turbos for sale?

[VitaminT]

jspec.com has used ones on their website. I do not know if they actually have any or how many.

[91 240]

Actually, Enjuku's 544hp run was on a Precision SC61 turbo. ReRead. Or ask.

[240SXer]

So a S15bb could make 350whp pretty easily? I know i'm gonna need MAF and Injectors, I want to run in the 12s, but I also want it to be as fast as possible on pump gas. I don't know how turbos work with that.

well regardless, they put down 496RWHP on the T3/T04E i know that for sure...so the kit does have a 500HP potential

nope, 350 would be a max power with crazy cams and valves and higher redline and lots of high priced tuning. The S15 BB T28 isnt about max power though, it spools very very very very fast.

The disco potato turbo is stupid, if you have ever seen it on SCC's car, they only got it up to ~270hp. What a deal, twice the price and a lesser power curve than the s15 T28.
