What Can This Turbo Do? T3/rx7 Hybrid...

[Roy]

^ yes and it was a very laggy thing

the highflow

Ive asked my boss about these rx7 style highflows and he swears at them

x jms owner so he would have experience with that s13 wt rb20

Well in 2001 two JMS cars rocked up to a UAS day at Wakefield, the S13 with RB20 with this turbo setup was not laggy. The combo of the engine and the nutter driver had me kind of thinking i was too young to die Like i said, i walked away doing my numbers about wanting that turbo for my car....but at the time my car was way too std to be worrying about a turbo upgrade

The bearings and seals are all brand new, and yeah i never said i would buy it, i just wanted to ask.

THANKS

And there is 20 different ways to high flow a turbo.

What makes you think this is done exactly the same as the one you were looking at?

I still don't have my specs to tell hows its going to perform either?

[WogsRus]

i'm working on the specs

Settle Kettle How many Skyline high flows have you heard about using Hitachi/RX7 bits? I only know of one place and thats ATS, so odds are its from the same place and very similar spec...im just answering the guys question

As for specs..all very interesting but i would trust seat of the pants experience over a few charts everytime

the TD06 was a much better setup

according to those in the know

so happy dance for Roy

ps I missed out on a TD06 25g setup for my new car Roy

Im very Emo it went super cheap to grrrrrrr

OK got some close up pics and some more info, but in reality the guy has no idea about it.

How does one find out what trim a compressor/turbone wheel is?

REPLY for my email:

""""""""""""""Turbo has beeen run, i used it for about 2-3 months on my car at around 12psi.

I do not know the A/R

Compressor Size (mm) : The inlet is 2 and a quarter inches ?

Compressor Trim: i do not know what this means

Compressor Cover Ratio and what it's off: Cover is from a series 4/5 Rx7

Turbine Size (mm) : i do not know what this means

Turbine Trim: i do not know what this means

Turbine housing Ratio and what it's off: Exaust housing is from a skyline. I have a rb20 standard turbo and the exaust housing look the same except this one has a much lager exaust wheel.

I will take some more photos tonight. here is the photos i had when it was rebuilt tho and 2 pictures of a standard rb20 turbo, so you can see the diference in the exaust wheel.

the person who build it said 300 hp would be achevable, however i was never dynod or tuned so i can confurm anything.

Im sorry i do not have much details, im not verry good with turbos."""""""""""""""""""""""""""""

300Hp seams a bit low, but i recon this might be ok. I know what you guys think but do these pics help any more at all????

[paulr33]

if it was a good turbo then he would have kept it and got it tuned etc

i suspect he is selling it cos it sucks. rotaries flow completely different to std piston engines so you may find its laggy as a bitch

and then when it comes on, it might be ok. he might have had issues with it surging its ass off while ramping on boost (who knows, and thats the honest truth). i mean its your call. whats the total cost to fit this turbo to your car?

[WogsRus]

ALSO found this, apparantly same front

http://www.boostcruising.com/forums/lofive...hp/t112508.html

Cost of teh turbo to bolt up including turbo is $200. with warranty left on the reco job. He is selling as he has no idea about car by the looks of things and crashed the car.

[WogsRus]

If the rear cover is same as an Rb20 turbo high flowed the rear should be ok? Correct?

Still not saying i'll buy it, just want to know if the pictures help at all?

[WogsRus]

One other thing i noticed, is that the front turbo compressor looks totaly different to the stock HT18S-2S turbo form the Rx7, so humm who knows.

[Tangles]

nothing wrong being a black sheep.

Ive heard of rx7/rb25 highflows doing a good job... word of mouth tho

if its $200, then buy it. if its a dog once installed then send it to Slide and have it redone. will still come in at same price roughly to a new slide highflow. as i said before. sometimes youve got to take a gamble and go by your gut feel.

[Ceffy_SA]

I have one on my Rb20 cefiro engine, its a HT18S off a S4 Rx7 which has been rebuily by ATS at some point. The turbo also has a Rb20 exhaust housing that has been modified to fit onto the turbo still keeping the original steel turbine though. It has made 160RWKW on 10psi and full boost (18psi) comes in around 3000-3200rpm, turbo spool up isnt the best though. My car has been off the road for some time so i haven't been able to dyno it at 18psi, not a bad turbo though, i only paid $500 for mine.

[Devils_Advocate21]

Surely he would have a sheet from the reco of the turbo on what they did, and IF they replaced the core/wheels on it, the only way to measure wheel sizes is to remove one housing at a time grab some verniers and measure the outside of the wheels. That said id say 300hp would be acceptable for a turbo of that nature but not too much more.

Just remember although it is good to try something different, your paying dyno time aswell for tune etc. If your not happy with it thats going to waste your money, im pretty sure thats what people are trying to say about unknown hybrids vs A brand you can trust, its a gamble at the end of the day, but one that costs money

Good luck with it

[WogsRus]

thanks guys, tunning is not a worry so much, just trying to get more details on the dam thing. Still cheep to buy and get slide to fix her up.

[discopotato03]

I would ring Aron up and tell him or show him pics of the thing before buying it . If the turbines exducer diametre is larger than the turbine he uses then the exhaust housings no good . For a bolt on he'd probably prefer the compressor housing from a std RB20 or 25 turbo .

Guys there really is nothing magic about the Hitachi bush bearing cartridge . Dimensionally tis very similar/same as a Garrett T3 and probably made under license - nothing special .

At a guess I'd say JMS used a combination of parts to have a "turbo" made because the bits were lying around . I think years ago I tracked down the people who dynoed that car with that Hi Flow and they admitted that is was surgy and laggy and only made some Ok numbers at higher revs . In its final form I believe that car had some form of rotary Jap aftermarket IHI turbo fitted and being developed from a proper set of components worked to a degree though if memory serves me correctly the turbine housing was rather large .

My advice is don't buy anything with an 8/16 blade T04B compressor because any turbine worth having won't work even passably with it .

A .

[WogsRus]

thanks guys, well go some more details. originaly the tubo was setup for an R31, but ran on a Rb20. The turbo was built, recoed by ATS in vic, so i'll be giving them a call soon.

Thanks for all the advice guys, i'm going to send the pic to Aaron and see what he says, but the turbo is as new, in teh sence of a rebuild. The guys tells me, if it's true, that the turbo was ran for 3 months after rebuild, and then the engine died so he is goind to a different engine.

Anyway will see what i do, might be worth a try. Wait to see what else i can dig up.

[R32_Matt]

is it a bush or ball bearing core?

does the owner know. You dont wanna buy it and then starve the bearings cause its a bush bearing, or flood the bearings cause its a ball bearing!

[WogsRus]

it's a bush bearing 360 deg thrust.
