Hi i have done abit of reasearch on considering going 2.35 as this seems to be the way forward to get over 650hp safely. Could someone who has ventured down this route please shine some lights on costs eg how much for shortmotor? Race heads? Ecu? Turbo? Etc etc. Any help would be much appreciated. Thanks

LOTS. I looked into this and it was getting near 10K!!!!

If you need the whole kit and kaboole then you can easily kiss goodbye to 20K
Especially if you need ecu,rotated kit and turbo plus engine with race cams etc

Lol cheers lads sounds like 10k would just tickle the idea i suppose i would get some ££££ back for my old bits. And what would be the limits of this type of block? Bhp/torque.. peak power?

im up to 645bhp so far on a 2.35, will be mapping for nos and race fuel this week...

BILLETBEANZ

iTrader: (1)

Very impressive banny Are you expecting to go past 800 on race fuel?? What box you using ?

banny sti

iTrader: (68)

Nah nowhere 800 as the turbo wont flow enough for that, anything over 700 will be nice and its on a UK hawkeye 6 speed box

F1 CJE UK

iTrader: (8)

very easy to spend 10k-20k + the cost of adding a 6 speed to your WRX

BILLETBEANZ

iTrader: (1)

Cheers buddy.. do people use the hawkeye sti 6 speed because of its longer ratios? Or would a normal 6 speed do the trick?

stonejedi

iTrader: (51)

To answer your question a lot of cash,dedication and patience is needed.as above for the block and head rebuild.you don't really need a billet crank unless you can afford it what was not mentioned was after Market ecu,turbo,rotated kit,parallel fuel rail set up,external fuel pump Etc etc etc..........

stonejedi

Any Subaru impreza sti 6 speed gear box will do the job with the right clutch.

Cheers mate. Im in two minds now i have a spare type r shell do i build this from scratch or do i sell the bits out of my current type r and keep the bits i need.. hmmm decisions decisions.. im thinking selling my current type r which aint no shambles at 515hp built by ET to raise funds for the 2.35 as this is defo the way i want to go.. hmmmmm any input on what i should do??

Hi there

You should ask yourself if you are need 2.35L.If you are already running nice bhp and in classic have 500bhp is great

In most cases 2.1L is good option,but if is budget yes 2.35L is without the doubts best option

About the cots,depends on parts used and would speak with engine builders here and ask them about the prices

As above Billet crank is luxus what you will don't need,standard crank is good enough for high bhp

I would buy parts from USA where cost lot less like here and you will save money on other bits

We are going with 2.35L too,but engine/heads and everything about that has been specced by Neil@Slowboy racing and really I would suggest speak with few people about the best option like is MartynJ@ET,Paul@Zen,Neil@Slowboy racing etc

As Jura said with 515 bhp already I would of thought that kind of power in a classic Subaru frame would be wickedly quick on the streets so the question you have to ask yourself is the extra outlay to build a 2.35 really worth it?

BILLETBEANZ

iTrader: (1)

Cheers lads for the advise, 515hp is mental for a road car i couldnt agree more but having just got 3 point totalling 9 now im turning to track use stricktly so the need for extra power is being explored. What would be the difference in running 2.1 to 2.35? Is there a great difference in peak tollerence between the two?

Just to throw another mad idea in, have you seen JGM's 3 litre 6 cylinder build in projects????

jura11

iTrader: (7)

On track you don't need too much power(if power sometimes helps),on some tracks you will need more spool than power,on drag strip would say yes,power is everything,but still would rather spend money elsewhere like on suspension upgrades and good wheel alignment

2.1 vs 2.35,peak tolerance/power,depends on turbo which is used,with 35r I would suspect will be laggy without the AVCS,with AVCS should be spool better,but not as on 2.35L

If you will be using properly sized turbo like 30r or Twin scroll 30r/Borg Warner EFR range I wold say on 2.1 will be OK,but still on 2.35L will be better

Depends on your targets and on budget,from this I would choose,if 2.1L will be good and cheaper option or 2.35L will be better option on longer run

As many people here suggest,speak first with tuners which building the engines

Cheers Jura your advise is much appreciated, after a good long thought ive decided to part with my current spec type R, sell this as a whole car as it would be a shame to break it after just throwing almost 7k at it and start fresh once it has sold.

Spoke to ET and a 2.1 with avcs heads might just meet my requiremnents so possibly go down this route with abit of nos if required.

Will be posting a for sale add soon for my current spec type R so if anybody is intrested in a 515hp ET built type R please do get in touch.

Cheers lads for all the advise you have been great as always.

resurrecting this thread as im on the hunt for my 05 sti to go to a forged 2.1. I really know nothing about this part of tuning side so any help would be appreciated. my car is running 440 on meth but I want more torque for a more aggressive feel. whats the cost of a 2.1? will this be the right way to go etc?? any advice is welcome
thanks

It's a slippery slope craigyp when you start a engine project,but yes 2.1 would be a less problematic way of doing it as you just get the stroker kit,lateral performance do a good kit at good money,and you use your existing block,but if it's an improvement in torque your looking for really you should be looking at doing headwork and cams as well to release the extra torque and rev range.££££ good luck with any decision you make.SJ.

Hi Craig

Depends how much bhp you are want and if for you will be enough 550bhp build 2.1L or do you want in future go with bigger turbo etc.

If you are looking for build 2.1L then I would speak like over here MartynJ or AlanJ about their 2.1L options

2.1L and MDX321T is great combo and with right supporting mods you will have matched toque and bhp figure like in our case 490/480 or 452/440

About the cost of the 2.1L,have look on this
