DET or Turbo Kit?

right now, im thinking of swapping in the sr20de with lower miles and putting a turbo kit on or just getting the sr20det. which do you think would be cheaper and more reliable?

Get the regular DE then turbo it with a Fmax Stage 1 or 2 if you want more power. You'll have to get some custom piping done but you'd have to do that anyway with the DET.

would that be cheaper than the getting the DET? with installation i mean. and do you have the fmax site address?

no clue on prices, but go here http://www.f-max.com/NISSAN.htm

yeh, I might consider turbocharing my G too, considering the sloooooooooooooooooooooooooooooow acceleration I'm getting from it now. mine's a AT so, other than turbo or NOS, its basically hopless. :cool:

Jason, what custom piping are necessary for SR20DET swap?

Thanks

I would rather get the DET motor...the turbo kit will cost MORE than the motor and why not just get something that's already turboed with the proper internals?
From me, DET motors, fully compression tested, leaked down is $1500 plus shipping. That's not including ECU/harness but you can use your factory ones with the help of a fuel controller or tuned ECU by JWT or others.
hmmmm....i must have type the above info 2 million times...hehehe...and then P10DET will reply saying that it's cheaper to get a DE and then turbo it IF you wanna do all out 500hp car...(which is not desireable for street or track....only if you are interested in going in a straight line for 12secs or so...)

Unless you want to cut a hole in your hood for the top mount IC, you will need to get pipes for a front mount IC. You will also need a turbo downpipe regardless.

Or, wait for HotShot to come out with the DET installation kit I'm prototyping for the P10. :D

If you have a P11, you will need to get pipes made up.

I agree.

Actually, I think the threshold is going over about 250-260 hp and doing a rebuild on the engine. Around 250-260 is when you have to replace the turbo, exhaust manifold, MAF, and injectors. This only matters if you are going to do a rebuild though. That is the important thing you didn't mention. If you aren't doing a rebuild, the DET is still the better place to start.

The rebuild is the key. If you're rebuilding, you end up paying $1000 extra for the DET and all you get are piston coolers and sodium filled valves. JWT can do the piston coolers for $250 and Swain can coat the valve faces for less than $200 and that will be as effective as the sodium filled valves.

So, it's a matter of hp *and* doing a rebuild. :D

well, even if i do get the sr20det, shouldnt i replace the turbo anyways? cause ive heard most arent reliable.

George,

Do you have a good idea of when the HotShot G20 DET install kit will be ready?

Thanks

Cutting a hole in the hood because of clearance issues or because of effeciency issues?

They can be rebuilt.

It's a crap shoot regarding getting a good turbo. Fortunately for me a friend in SoCal went o Soken and found one in excellent shape for me. :D

No I don't yet. I just finished making the pipes and getting my car running. I don't know if I will send my current pipes or make another set to send to HS to make jigs from. I'm leaning towards making another set since I think I can do a little better job (this was my first attempt, but they came out better than most anyway).

I'll probably be some time in the fall as the earliest, but I can't even say that. I don't know what John's schedule is like. Right now he can sell all the headers he can make. I think by sending him completed pipes though will help the process. I'm sure it will depend somewhat upon demand.

SR20DET are VERY reliable..just keep in mind that since it's a turbo, you have to change oil at the suggested time, maintaining wise, it's not as scary as people think
about the Turbo upgrade, unless you are thinking about making your DET a power monster...(which at stock ratings with fine tuning can you get 250hp...THAT'S very powerful by any standard)
you would need to get a bigger turbo...meaning a new manifold meaning $$$. or you can get the HKS GT2530 ball bearing turbo which mounts right on the factory manifold...but are you prepared to pay $2475 list price for that? if you are, go for it, 300HP+ with that turbo alone.
what i am saying is, get the motor from me if you decided..i'll do everything i can visually to insure the motor is a good one (most poeple dont even have people checkingout the motor before sending itout) and once you get the DET in, if you want more power, we'll go from there

Oh efficiency, totally, or technically, effectiveness.

The TMIC is only effective at all (with no openning in the hood) due to radiation of heat, but it can quickly become a heat sink.

A FMIC is the way to go, but you can install a hood scoop and create a seal between the TMIC and the openning in the hood. Almost everyone I know who has installed the TMIC has converted to FMIC. The FMIC is much more effective.

thanks for the insight guys. ive decided to go with the det, but i know i wont be getting it for a while. how much do you think getting the det and all the parts i need will cost me? damnit... got to get a job now. :bloated:

Not true Luke. Over 250 or 260 hp you *have* to upgrade the MAF and injectors as well. But, you're right, you don't have to replace the manifold. It's a cool turbo though. :D

Boy guys, this is a big plus, buying from Luke. Like I said, buying a DET is a bit of a crap shoot because too many turbos are shot. If Luke will check them all out in advance for you, there is no reason to look anywhere else. Just have patience though since he will probably reject a number of them.

George, thanks for your replies. You are definitely an asset for the G20 community.

HKS does claim with their ball bearing turbo, u can get 300HP with just that...i dotnknow about the MAF, but i think the factory DET motors, comes with 370cc injectors and that should be okay for the HKS turbo...anyway, if you do have enough money for that turbo, just upgrade everything else while you're at it hehehe.
after my swap goes in, i amjust gonna save up for that turbo and my engine would be complete for me. sat in a silvia with a big GT3037 turbo...man!!! so damn smooth and virtually no lag cuz of the ball bearing system..that car dynoed at only 320hp or so...but the pick up is amazing exiting corners....yummy

The turbo is good for it, but the MAF and injectors are not. You might make it with the injectors, but they would be constantly open and that is way into the danger zone. The MAF definitely isn't good for that. You'll need a Cobra MAF.

Oh many, you really should hook up with the SoCal SERCA folks. Aaron LeBeau just completed the assembly of his F-Max Stage III with equal lengh runners and merge collector (SS BTW) on the manifold with a 3037. All accounts have been quite impressive.

MMMM Turbo!
