As above anyone fitted a 20g to a type r v3 without being forged and standard gearbox and how long it last? cheers rob

 

Don't think 5 speed box will hold out well, also if you have it mapped at low boost to preserve engine and box you would just have a laggy car for no real reason would be much better mapped on smaller turbo 16g would make most of what you have and be much better drive

 

its only a w,e car so if it went wouldn t be end of the world. im mapped to 300 ish already but want more .

what about 18g anyone got 1 on a type r v3?

 

i had an 18g on my version 4 wrx with the standard box and it was fine for a good year but when i went to a 20g my box went to and no i have a six speed

 

oh and i had a forged engine for both turbos

 

to be there i would get your self a nice vf35 on there and have a nice quick 340hp

 

was just gonna write on here what would see me to a good 350hp?

how long box last with 20g lol

 

anyone

 

well mines running 360bhp and the box well new one going in asap lol

 

Gearboxes are a lottery TBH, I ran my 20G on my TY752 box now for a long time years infact and it never let go, trackdays included. Mechanical sympathy goes a long way though.

 

ok when u say mechanical sympathy does this mean launching or smashing through gear s ect ? how the 20g feel on that box with the ratios ect? cheers dunk

 

Launching or smashing through gears isn't being very sympathetic lol

With the close ratio box I was always in the power band, acceleration was very quick it felt pretty rapid TBH.

I'm not saying you will get away with it though, it might last a day, week month but it will go sometime thats for sure, previous use has alot to answer for as well.

 

but u said yours last a good while. im thinking of throwin 1 on see what happens lol il just be carefull with the launching lol


sonic vr6 are u getting probs with your box then?

 

you could say that got new one lined up i've lost 2nd and now pop's out of 1st lol but got one fro 350 fitted going to be alot nicer to the next one lol oh and wines in 5th lol the hole car's only done 50k

 

ive got an 18g on my v4 sti ra and its an awesome turbo, very responsive, the 20g is only better at 7k plus, the 18g beats it power and torque wise all the way upto those revs. my gearbox is still ok and ive been doing some sprint type events and i rag it including launches

 

it's a lottery on them i think i was just unlucky

 

20G on a V4 with standard internals @ 405bhp & a TY754 box with hard launches & not had a problem. Hookie ran the same power through it too & god knows what power Banny ran it at before him..!
It's torque that kills things & the 20G isn't very torquey..

 

is this on a 52 box mate oh maybe il go for 18 g then. what power u make

 

Not even a lottery on the gearboxes, enough TY754's have gone with 300lbs of torque through them, that includes STI boxes with hardened gear sets, then your engine really does have its life reduced running above 350bhp, the rods are weak and tend just to let go, you dont even have to be ragging it, just cruising down the road will do it, pop, bang, smoke, fire even, and classics are reknown not to have strong rods again its luck of the draw but its also big borrowed time.
I would stick with a nice responsive turbo and run 340/350bhp, you will just obliterate these big laggy turbo'd cars on the road, especially in the twisty stuff where you need the quick pick up

hmmm 400 in a type r would be so much fun i just don t wanna blow it up 1st week

 

It will cost you about 10k to do it properly, you can buy a spec c with 26k on the clock (one on pistonheads) for that, and its a quicker/better handling/more enjoyable car

Tony

 

tony what about a 18g? what ever happened to splitpin?

 

tony u and your spec cs lol u must miss your type r

 

tony know's his stuff buy the way i got mine all checked out they new the car and said that it was built for more power but the fmic had been taken off the timer and the boost controller basicly raped when the bloke part ex'd it lol they even new the spoiler was adjustable i had no idea 22b one buy the way will post some pic's when rain stop's

 

I still have my v5 STI Type R just need to get it back on the road, got some time off coming up so will replace the fuel line thats fubar just hope the weather is nice

Tony

 

see so u do miss your type r admit it its better more fun than spec c ..lol

 

2 different cars really, the Spec C is a nicer place to be, more fun to drive, but the type R looks more agressive and 3 door scoobs are nice

Tony

 

Don't worry, I've got a reconned TY752 gearbox on eBay at the mo waiting for you!
As everyone says a nice minimum lag 350hp car is pretty balanced.

If I did it again I'd just buy a GT30 & not bother with journal bearing turbos.
Just my thoughts

 

what an chuck it straight on a type r lol i think i gotta change brakes 1st these 4 pots are no good when u wanna stop quick. so brakes then big turbo,injectors ect

 

Mines running 340/320 on standard vf23 turbo and box. No probs so far.
Dont see the point in getting a more laggy 18g or 20g just for a few more horses.
Especially if you have standard internals.
