The Turbo Project Begins! - Toyota Nation Forum : Toyota Car and Truck Forums

ericlee303 · 05-12-2002, 11:50 AM

I am on a mission to turbo my B18B Integra.
Unlike our 4AGZE project, I am in no rush to get this one done, as the car is already semi-fast. My bro and I found a junkyard with a couple of turbos in it, including one from a Mazda 626 (IHI).

The owner wants $100CDN which includes downpipe.

Does anyone suggest another turbo, and is this thing worth $100?

$100 is a good price

get the downpipe for sure and even take some of the charge piping.

you will want the intercooler from that mx6 as well, as it is a very pretty unit, only thing is that the re-bar has to come off... which could take 2 hrs approx. but it is worth it, sounds like this guy will charge you like $30 for the intercooler so yah it is pretty good

those turbos usually go for $150-$175,

its a nice unit capable of 6-8 psi.

here is more fire to fuel your turbo project, and yah... it really got me going, but too bad i have no cash.

i talked to this guy before, he is pretty cool, and knows his stuff...(after he blew 3 engines, ahhahha)

Yeah, cash is kind of a problem right now too, as I put myself into debt by replacing all of my suspension. I'm not too cool with that.

But like I said, I'll take my time on this one and maybe if I'm ghetto enough, I can get this done by fall.

Thanks Andrew!

I don't know much about the IHI turbos as far as specs go, but their good turbos.

You can find all kinds of turbos at junkyards. Garrett/AiResearch (T3), IHI (Ishi Warner), KKK, Mitsubishi (TD04H , TD05H), Toyota (CT26, CT20), Volvo, etc...

Just make sure theres no play in the shaft, the compressor and turbine wheel spins fine, no signs of oil leakage, compressor and turbine wheels are in good shape (no signs of damage), and no cracks in the housings (sometimes the turbine housing is cracked).

Most of the turbos i've seen on B18B / B18C are Garrett T04/T3 hybrids, but they usually just buy a kit (Drag turbo kit or something).

i'll be interested as to how it goes!
i _may_ be doing the same thing...or b16 swap...who knows!! :grin:

goodcookiedrift · 05-12-2002, 11:25 PM

yeah butare those turbos ball bearing? to be honest, a non-ball bearing turbo may not be the best because of all the associated lag.

I know that probably 99% of all t3 and t3/t4 turbos on those hondas are ball bearing...

eric if you're super serious, i can get my friend in australia to hook up a ball bearing t25 off of a stock r33gtst or a t3 ball bearing off of an s15.

The turbo is a great little turbo, might be a touch small for a B18, but will spool fast so a great street machine. The turbo is capable of 18 psi if you want! 100 dollars is what I paid for mine, and that seems like a good price Eric. Hope things work out for ya!

ericlee303 · 05-13-2002, 09:47 AM

Hey Sam, if your turbo was only $100 I'd rather buy one from whoever you bought it from (your mech?) because I know it would be in good condition. I'll keep in touch with you. Can you email me your phone number to eric.lee@gm.com?

SE V6 · 05-16-2002, 11:46 AM

It all depends what you want to get out of your car. How much hp are you looking to gain and how fast do you want to go in the 1/4 mile? These will determine what turbo to use.

Good luck!

BluSleeper19 · 06-20-2002, 01:17 AM

I like the 14b off of the first gen talons, they boost very quickly and they last a lot longer than any turbo i have seen. you can run the boost from 0 to 16 easy, capible of handling 350 hp. Zach

jdm_rex · 05-18-2004, 09:02 AM

ihi is the same thing that the apexi kit comes with just a upgraded version...the thing was capable of producing up to 300 hp..$100 bucks is worth the turbo..

neil85AE86 · 05-31-2004, 02:54 PM

the probe/mx6/626 IHI's are very small turbo, even tho they were installed on 2.2L engines, the engines they were installed on were 8 valve, with very low compression and very low volumetric efficiency compared to a B18, and the HP peak was around 4800 rpm. I have a copy of the engineering guide from IHI, as well as the compressor maps, the one you are looking at is rated for a maximum of around 160HP, which is conservative. The mx6 guys can squeeze 200 whp out of this unit when running at boost levels beyond the efficiency range of that turbo, which is only good for short stints.

Stay away from the RHB5 series period, in general their turbine is just too small for your B18, and just barely big enough for my 4age. If it spools quick on my 4ag, it will spool way too quick on your B18 and probably choke up around 5500 rpm.

A good junk yard turbo for your car would be a garrett air research T3 from a Mercury Merkur/cougar or Ford T-bird up to and including 1986. Be careful, some of them came with an IHI, make sure you get the garrett. These are either 60/48 or 60/63 trim units, it will still spool well on your B18 and will make upto around 300 HP at the wheels, and can run upto ~20 psi ( the 48 will spool quicker, the 60 will perform a little better at high rpm, the 60 is on the auto transmission models )

Definitely look at turboedit or uberdata for that car.

Good luck! Should make for a very fun ride.

Best wishes from Russia to all!

I’ve got a problem and would find some help here.

I’m going to blow one 1,5 liter engine and I must find suitable turbocharger. The idea is: to build a gasoline engine with a disiel character. I don’t wont “turn” it up to 3000 or 4000 rpm to reach the peak of a pressure, so I need a turbocharger which could give me pressure about 0,7 bar at 5 lb/min air flow ( it corresponds to 2000 rpm). Garrett GT12 is suitable for this purpose, but it is very rare and expensive here in Moscow. KKK K03 looks good too. Mitsubishi TD025 seems suitable, but I haven`t got its compressor map to be completely sure… Has anybody compressor flow maps of Toyota`s or IHI turbochargers? I would be very-very grateful for helping me…

Sorry for my English.

neil85AE86 · 08-02-2004, 08:04 AM

hmm... I understand what you are trying to do, the problem is to get the kind of performance you are after you'll need a very small turbine so you'll be boosting all the time, which will make for a really inefficient setup.

Some Isuzu have an IHI RHB5 with a pretty small compressor that is rated at about 130 HP or so, it might do what you need but I think the turbine side will be a little big. This has the same turbine as the turbo I'm using on my 1.6, I can get 5 psi by about 2700 RPM, if I mess with the timing, and restrict the inlet side (TVIS) I can get it down to 2300 or so.

You might want to find an IHI off an older suzuki 3 cylinder turbo.

kindly_spirit · 08-03-2004, 04:56 AM

Neil, thank you for your recommendation. I haven’t found compressor map for IHI RHB5 in the web and IHI gives some data for RHF series only. You have written above that you have got both of compressor map and a copy of the engineering guide from IHI, could you share it with me, please? (my e-mail: bluckwind@list.ru)
You see, I don’t wont to get a huge power in my project at high RPMs, but I would get a good flat torque from 2000 up to 5000-6000 rpm. So I have to get a peak pressure of the boost (0,7 bar / about 10 psi) and then to keep it constant, cutting it with wastegate. Something like that: http://not2fast.wryday.com/turbo/maps/k26_map.jpg

Meanwhile, I must not get into a surge zone at the low air consumptions. According my calculations, I’ve got 1.35 m3/min at 2000 rpm and 3.71 m3/min at 5500 rpm, the boost pressure ratio is constant – 1.71. Let’s look at this IHI data:

I suppose, RHF3 is the most suitable of all other: I can give it PR 1.7 already at 1.3-1.5 m3/min and at 3.7-4.5 m3/min I’ll be in the zone of quite good compressor efficient. What do you think?
Vladimir.
