The 18R-GTE reference manual ...

It could be done easy enough IF you have decent engine management and a good tune. Otherwise engine go bang.

engine management would be a microtech LTX-8 or 10

thats what i had in mind with a motec and kkr 430 turbo, is the cutom plenum really necessary?

i want a powerful 18rgt but it doesn't have to win horse power hero's or anything.

my budget isn't near that of say justins

what and a motec puter is with in your budget??

i just want something to cruise around it with a bit more balls than a standered 18RG

i could tell you the answer to your questions about the custom plenum but that would be like feeding a adult with a baby spoon,

check out the whole thread its on the 1st page off memory

Been meaning to post pics of the 3inch stainless dump and final wastegate plumbing...looks like a piece of medical gear it's so tidy

Wiring issues all sorted and it's running well....sounds hell tough with just a 3 inch hotdog.

Just sorting a few annoying issues like getting a rad hose that'll fit. Hope to get it to the exhaust shop next week and then to the tuner next door.

Progress is good...

g series diff with all the right mounts to go into the '23

Well we hit the dyno today for a tune session....hmmm ran out of injectors by 4K with 160hp at the treads and the curve only just starting to really ramp up.

Good news was useable boost as low as 1600rpm which surprised even me looking at the size of the turbine....gotta love our manifold design

Revs just sooooo smooth, feels like a 16v.

Gonna drop in some 13BT injectors if they'll fit this evening...otherwise on the search for 7MGTE i reckon...anyone?

[timbosaurus]

Beat you to the punch Steve...well kinda. I have a 22R cranked 18RGT on the stand and pretty well ready to go....

...Touch wood it should be installed in it's new home and grunting away within the month.

haha... was just looking back on this thread.

Justen... it's only 4 months overdue! not many of us can say our projects is that close to being on time! Hell... mine's 4 YEARS overdue!

Fark tell me about it.....no need to actually as the missus pointed in out every arvo she got home from work :-) Still, appears to have been worth the wait...just need those big injectors badly.

Injectors?... pfft! I've got a set of solex's back in qld you can convert to blow-thru if u like?

The 2T and 3T cranks are forged.

really? are you sayin that the stock one are or you can get them? and if you start to polish them or gring them will it change the strength of it at all?

[Steve M]

18R, 18RG and 21-22R cranks are also forged.
I wouldn't mind betting that just about all recent (last 25 years) petrol engines are probably forged cranks.
I speak of the stock ones. That's not to say that an aftermarket forged crank might not be a better item.

- you can get biggish injectors pretty cheap from Ebay motors! Do a search for DSM injectors, and pick out the 1st gen (often refered to as "1G") on the ebay motors site..... the 1G DSM injectors are 450cc/min and single point spray pattern which is perfect for the 18R-G head. Usually cost US$100/set4
The later model DSM injectors are a different spray pattern (better spread for multivalve head), and will give too much wash on the port walls of the 18RG head.

Otherwise the RX7 injectors are plentiful there too, and cheaper than australia.

[JustenGT8]

Yup all good thanks Witzl...lined up some series IV 13BT injectors which should slot straight in....back to dyno.

The final parts shots. A good dump like this is part of the key to getting 10psi boost from the monster turbo under 3000rpm and useable boost from 1600rpm.
